PART I
ITEM 1.BUSINESS
All references in this report to “Dermata,” the “Company,” “we,” “us,” or “our” mean Dermata Therapeutics, Inc. unless stated otherwise or the context otherwise indicates.
Overview
We are a late-stage medical dermatology company focused on identifying, developing, and commercializing innovative pharmaceutical product candidates for the treatment of medical skin diseases and aesthetic applications we believe represent significant market opportunities.
Dermatological diseases such as acne vulgaris (or acne), psoriasis vulgaris (or psoriasis), hyperhidrosis, and various aesthetic indications, affect millions of people worldwide each year which may negatively impact their quality of life and emotional well-being. While there are multiple current treatment options for these indications on the market, we believe that most have significant drawbacks, including underwhelming efficacy, cumbersome application regimens and varying negative side effects, all of which we believe lead to decreased patient compliance. A majority of these indications are first treated with topical therapies, however, many patients frequently switch treatments or discontinue treatment altogether due to patient dissatisfaction. This is primarily due to slow and modest response rates, early tolerability issues, once or twice daily application schedules and long duration of therapy. Given the limitations with current topical therapies, we believe there is a significant opportunity to address the needs of frustrated patients searching for topical products that satisfy their dermatological and lifestyle needs.
Our two product candidates, XYNGARITM (formerly DMT310) and DMT410, both incorporate our proprietary, multifaceted, Spongilla technology to topically treat a variety of dermatological conditions. Our Spongilla technology is derived from a naturally grown freshwater sponge, Spongilla lacustris or Spongilla, which is processed into a powder that is mixed with a fluidizing agent immediately prior to application to form an easily applicable paste. Spongilla is a unique freshwater sponge that only grows in commercial quantities in select regions of the world and under specific environmental conditions, all of which give it its distinctive anti-microbial, anti-inflammatory, and mechanical properties. The combination of these environmental conditions, the proprietary harvesting protocols developed with our exclusive supplier, and our post-harvest processing procedures produce a pharmaceutical product candidate that optimizes the mechanical components as well as the chemical components of the sponge to create a product candidate with multiple mechanisms of action for the treatment of inflammatory skin diseases and aesthetic applications.
We believe our Spongilla technology platform will enable us to develop XYNGARITM as either a single, stand-alone agent, or used together with other dermatology products to target the topical delivery of chemical compounds into the dermis for a variety of dermatology indications. We believe the combination of Spongilla’s mechanical and chemical components (which we believe have demonstrated, in-vitro, anti-microbial and anti-inflammatory properties), add to the versatility of our Spongilla technology platform’s effectiveness as a singular product, in the treatment of a wide variety of medical skin diseases like acne and psoriasis. We also believe the mechanical properties of our Spongilla technology allows for the intradermal delivery of a variety of large molecules, like botulinum toxins, monoclonal antibodies, or dermal fillers, to targeted treatment sites, through topical application without the need for needles.
Our lead product candidate, XYNGARITM, is intended to utilize our Spongilla technology for the once weekly treatment of a variety of skin diseases, with our initial focus being the treatment of acne, which has a U.S. market size of approximately 30 million patients seeking treatment. In November 2024, we completed patient enrollment in the first of two planned Phase 3 clinical trials of XYNGARITM in moderate-to-severe acne. We expect to receive top-line results from the first Phase 3 trial in March 2025. Each Phase 3 study will be double-blind, randomized, placebo controlled, and enroll over 500 patients with moderate to severe acne, age 9 years or older across sites in the United States and Latin America. The primary endpoints include absolute reduction in inflammatory and noninflammatory lesions and the improvement in investigators global assessment (IGA) of acne. Patients will be treated once a week for 12 weeks with either XYNGARITM or placebo and will be evaluated monthly. As requested by the FDA, the second Phase 3 study will be followed by an extension study to follow patients for a 12-month total treatment period.
Table of Contents
Previously XYNGARITM has shown its ability to treat the multiple causes of acne in a Phase 2b study where we initially saw a 45% reduction in inflammatory lesions after four treatments, with XYNGARITM achieving statistically significant improvements at all time points for all three primary endpoints throughout the study (reduction in inflammatory lesions, reduction in non-inflammatory lesions, and improvement in IGA). In addition, based on the multiple mechanisms of action and anti-inflammatory effect seen with the XYNGARITM acne trial, we completed a Phase 1b proof of concept, or POC, trial in psoriasis where we saw encouraging results warranting further investigation upon our receipt of adequate funding.
XYNGARITM consists of two grams of powder processed from the naturally grown freshwater sponge, Spongilla lacustris. The patient mixes the powder with a fluidizing agent (3% hydrogen peroxide) immediately prior to application to form an easy-to-apply paste. The paste is applied like a mud mask and is left on the skin for approximately ten to fifteen minutes, after which time it is washed off with water. Due to the unique combination of XYNGARITM’s mechanical components and chemical components, and based on our Phase 2 acne data, we believe patients will only need to apply XYNGARITM once weekly to produce the desired treatment effect. The mechanical components of the Spongilla powder consist of many microscopic siliceous, needle-like spicules that, when massaged into the skin, penetrate the stratum corneum (the skin’s outermost protective layer) and create microchannels into the dermis where pro-inflammatory cytokines and bacteria reside. We believe that the penetration of the spicules also leads to the opening of microchannels, which allow oxygen to enter pilosebaceous glands, helping to kill C. acnes, which grow in an anaerobic (without oxygen) environment (C. acnes are the bacteria that cause inflammatory lesions in acne patients). The spicules also cause turnover of the top layer of dead skin, thereby increasing collagen production resulting in skin rejuvenation. Additionally, we believe the newly created microchannels provide a conduit for XYNGARITM’s naturally occurring chemical compounds to be delivered to the dermis and pilosebaceous glands, helping to kill the C.acnes and reduce inflammation. In addition to anti-microbial compounds, XYNGARITM also appears to have anti-inflammatory chemical compounds, as demonstrated during in vitro experiments, that inhibit inflammation through the reduction of C.acnes stimulated IL-8 production and by inhibiting IL-17A and IL-17F expression in human cell lines. Also, during in vitro studies of XYNGARITM’s organic compounds, we observed the inhibition of the lipogenesis of sebocytes, which may translate to a reduction in sebum (an oily and waxy substance produced by the human body’s sebaceous glands) production and the oiliness of the skin in patients, which was observed by a number of clinical investigators in our Phase 2 acne studies. We believe the combination of these biological and mechanical effects could be important factors in treating multiple inflammatory skin diseases, as seen in our clinical trials.
Our second product candidate utilizing our Spongilla technology is DMT410. DMT410 is intended to consist of one treatment of our proprietary sponge powder followed by one topical application of botulinum toxin for delivery into the dermis. Currently, botulinum toxin is only approved to be delivered to the dermis by intradermal injections, which can be painful for the patient and time-consuming for the physician. However, we believe DMT410’s ability to topically deliver botulinum toxin into the dermis could have similar levels of efficacy to existing delivery techniques, with fewer tolerability issues, and a quicker application time, possibly replacing the need for intradermal injections. We first tested DMT410 in a Phase 1 POC trial in primary axillary hyperhidrosis patients where we observed 80% of patients achieving a reduction in gravimetric sweat production greater than 50% four weeks after a single treatment. With almost 40% of the hyperhidrosis market currently being treated with intradermal injections of botulinum toxin, we believe there could be significant opportunity for DMT410 to break into this market and replace intradermal injections of botulinum toxin. Based on DMT410’s ability to effectively deliver botulinum toxin to the dermis as observed in the Phase 1 axillary hyperhidrosis trial, we also conducted a Phase 1 POC trial of DMT410 for the treatment of multiple aesthetic skin conditions, including reduction of pore size, sebum production, and fine lines, among others. In November 2021, we announced top-line results from this trial, where we saw promising data that we believed warranted further investigation of DMT410.
On January 17, 2025, we entered into a Clinical Trial Collaboration Agreement (the “Clinical Trial Agreement”) with Revance Therapeutics, Inc., who recently merged with Crown Laboratories, (“Revance”), pursuant to which we in collaboration with Revance intend to conduct a multi-center Phase 2 clinical trial to evaluate the topical application of XYNGARITM, with DAXXIFY® (daxibotulinumtoxinA-lanm), Revance’s botulinum toxin type A, for the treatment of axillary hyperhidrosis (the “Trial”).

Application of XYNGARITM
Image 1: The Spongilla is processed into a fine powder and packaged into 2g pouches with a 6mL bottle of 3% H2O2 (hydrogen peroxide). Once per week, patients mix the powder with hydrogen peroxide, and massage the mixture onto their skin; after 10-15 minutes the product is easily removed with water.
We believe that the current medical and aesthetic dermatology landscape lacks innovative treatment options, with new treatments predominantly being the introduction of reformulations or combinations of old molecules. We believe this lack of innovation provides an ideal opportunity for us to change how patients treat their skin conditions. With our anticipated once weekly treatment schedule and product candidate derived from a natural source, we believe we can become a leader in the space that may improve patient compliance with minimal side effects and a rapid time to treatment effect, as seen in our multiple clinical trials in acne, psoriasis, hyperhidrosis and aesthetic conditions. If we can successfully develop our product candidates, receive FDA approval, develop a concentrated prescribing base of dermatologists, and utilize our management’s prior experience, we believe we have the ability to build a commercial organization to develop and commercialize treatment options in our core areas of focus within the dermatology space.
Our Clinical Development Pipeline and Product Candidates
Our clinical development pipeline currently consists of XYNGARITM and DMT410, each in development for multiple skin diseases and conditions. In the accompanying section we will describe each product candidate, its benefits, and our market strategy for each product candidate. The dates reflected in the below table and sections are estimates only, and there can be no assurances that the events included in the below table or sections will be completed on the anticipated timeline presented, or at all.
XYNGARITM
Moderate-to-Severe Acne. In December 2023, we began enrolling patients in the first of two Phase 3 clinical studies of XYNGARITM for the treatment of moderate-to-severe acne, entitled the Spongilla Treatment of Acne Research (STAR-1) study. Each study will be double blind, randomized, placebo controlled, and enroll over 500 patients, age 9 years or older across sites in the United States and Latin America. The primary endpoints will include the absolute reduction in inflammatory and noninflammatory lesions and the improvement in investigators global assessment (IGA) of acne as were used in our XYNGARITM Phase 2b acne study. Patients will be treated once a week for 12 weeks with either XYNGARITM or placebo and will be evaluated monthly. In November 2024, we completed enrollment of the STAR-1 study with a total of 520 patients. The STAR-1 Phase 3 study is expected to have top-line results in the March of 2025.Previously, we completed a randomized, double-blind, multicenter, placebo-controlled Phase 2b clinical trial of XYNGARITM for the once weekly treatment of moderate-to-severe acne. XYNGARITM showed statistically significant improvement versus placebo for all three endpoints (inflammatory lesion counts, non-inflammatory lesion counts, and IGA), after only four topical treatments and continued to statistically separate from placebo through the end of study at week 12. We believe these results from once weekly applications may favorably position XYNGARITM as a first-in-class product in the market for the treatment of moderate-to-severe acne, if approved.
Mild-to-Moderate Psoriasis. In October 2021, we completed a Phase 1b POC trial of XYNGARITM for the once weekly treatment of mild-to-moderate psoriasis. Plaque psoriasis is a chronic, inflammatory skin disease that comprises approximately 80% of the psoriasis market as of 2019, according to Fortune Business Insights Market Research Report, a majority of patients have mild-to-moderate disease which makes them less likely to receive an approved biologic treatment, that are only indicated for patients with moderate to severe disease, as a first line therapy. Due to the large population of patients who suffer from mild-to-moderate psoriasis, and lack of effective topical therapies for more mild disease, we believe there is a large unmet need for an effective topical product with limited side effects. Based on the data in our Phase 1b POC trial, the in-vitro data of XYNGARI’sTM reduction of IL-17A and IL-17F, and the anti-inflammatory effects we observed in its Phase 2b trial for acne, we believe XYNGARITM may be used as a first-line therapy for patients suffering from mild-to-moderate psoriasis who are not candidates for biologic treatments. In October 2021, we announced top-line results from our Phase 1b POC trial of XYNGARITM for the treatment of 30 mild-to-moderate patients with psoriatic lesions covering between 2% to 30% of their body surface area. Patients were treated with XYNGARITM once a week for 12 weeks. Based on the efficacy, safety and tolerability profile observed in the POC trial, we initiated additional work to better inform our clinical trial design prior to moving into a larger Phase 2, placebo-controlled, clinical trial. We plan to continue development of XYNGARITM for the treatment of psoriasis upon the acquisition of additional financial resources to support such development.

DMT410
We are developing the second product candidate from our Spongilla platform, DMT410, for the topical treatment of skin diseases and aesthetic conditions typically treated with multiple intradermal injections of botulinum toxin. Currently, botulinum toxin must be intradermally injected multiple times to successfully deliver enough botulinum toxin to produce the desired effect in the desired treatment area. While injections are effective for many different diseases and aesthetic conditions, they limit botulinum toxin’s use for additional conditions where injections, especially intradermal injections, are difficult, painful, or otherwise not viable. Some of these conditions include hyperhidrosis, acne, acne scars, and various aesthetic indications, of which DMT410 could be a viable treatment option. DMT410’s treatment regimen uses one application of our XYNGARITM followed by one topical application of botulinum toxin. The Spongilla powder is mixed with a fluidizing agent and is massaged into a patient’s treatment area by the treating physician to enhance spicule penetration to create microchannels into the dermis. After 10 to 15 minutes, the physician removes the Spongilla mask with water. The physician then expresses botulinum toxin from a syringe in precise amounts and onto the patient’s skin. The botulinum toxin is then massaged into the treatment area to take advantage of the microchannels created by the Spongilla’s spicules, which allows the botulinum toxin to penetrate the stratum corneum and enter the dermis. We believe this treatment application will enable the topical delivery of botulinum toxin into the dermis for the treatment of a variety of medical diseases, including for the treatment of hyperhidrosis, acne, and acne scars, as well as improving the skin’s luminosity, brightness, and reducing pore size and count, fine lines, and sebum production. We believe DMT410’s topical delivery of botulinum toxin can greatly increase market opportunities for botulinum toxin due DMT410’s needle-free application, targeted intradermal delivery, thus potentially expanding the aesthetic market for botulinum toxin.
To date, we have completed an open-label Phase 1b POC clinical trial of DMT410 for the treatment of axillary hyperhidrosis and an open-label Phase 1b POC clinical trial in multiple aesthetic skin conditions. The Phase 1b POC trial for axillary hyperhidrosis consisted of 10 patients receiving one treatment of DMT410 to each axilla. Four weeks after one treatment with DMT410, patients exhibited a reduction in sweat production. The clinical endpoints for this trial included (i) percent of patients with greater than 50% reduction in gravimetrically measured sweat production from baseline, (ii) percent of patients with gravimetric sweat production less than 50mg, and (iii) percent change in gravimetric sweat production. Four weeks after one treatment with DMT410, 80% of patients experienced a decrease in gravimetric sweat production greater than 50%, 85% of patients recorded gravimetric sweat production of less than 50mg, and patients had an average decrease in gravimetric sweat production of 75% from baseline. We believe these results demonstrate that DMT410 may aid in the topical delivery of botulinum toxin into the dermis for a treatment effect similar to multiple (estimated 15-20) intradermal injections of botulinum toxin. With DMT410, we believe botulinum toxin may be applied topically to penetrate the skin into the dermis without the need for multiple injections.
We also completed an open-label, ten (10) patient, Phase 1b POC trial of DMT410 for the treatment of multiple aesthetic skin conditions (pore size, Global Aesthetic Improvement, brightness, luminosity, sebum production, fine lines, glabellar lines, forehead lines, and lateral canthal lines) and announced topline results in November 2021. In our Phase 1b POC trial of DMT410, patients received one treatment of DMT410 and were evaluated every four weeks for a total duration of 16 weeks to determine DMT410’s safety and tolerability profile, effectiveness, and its duration of treatment effect. We announced top-line results in November 2021, where we observed an improvement in many of the trial’s endpoints. At week 8, 80% of patients had at least a 25% improvement in their Global Aesthetic and 60% of patients had a 25% improvement in pore size. Also at week 8, 90% of patients had at least a one-point improvement in luminosity and 60% of patients had at least a one-point improvement in brightness. These physicians graded results were supported by objective analysis provided by Canfield Scientific’s VISIA and PRIMOS visual analysis camera systems. Based on these results, we continue to actively discuss partnership opportunities with botulinum toxin companies to continue development of DMT410 in a larger placebo-controlled Phase 2 trial where we can study multiple doses of botulinum toxin applied to the entire face. We believe these results, combined with our results in hyperhidrosis, clearly demonstrate how DMT410’s combination regimen could greatly expand the potential indications for botulinum toxins for aesthetic skin conditions, as well as other dermatologic skin diseases such as hyperhidrosis, acne, or acne scars.

In January 2025, we entered into the Clinical Trial Agreement with Revance pursuant to which we in collaboration with Revance intend to conduct a multi-center Phase 2 clinical trial to evaluate the topical application of XYNGARITM, with DAXXIFY® (daxibotulinumtoxinA-lanm), Revance’s botulinum toxin type A, for the treatment of primary axillary hyperhidrosis. Under the Clinical Trial Agreement, we intend to sponsor, conduct, and fund a Phase 2a clinical trial to evaluate the safety, tolerability and preliminary efficacy of XYNGARITM and DAXXIFY® versus XYNGARITM and placebo in patients with moderate-to-severe axillary hyperhidrosis for 16 weeks. The axillary hyperhidrosis trial is anticipated to be randomized (1:1:1:1), double-blind, dose-ranging, placebo-controlled, and intends to enroll approximately 48 patients across sites in the United States. The endpoints are anticipated to be (i) the percent of patients with greater than 50% reduction in gravimetrically measured sweat production from baseline, (ii) the percent of patients with gravimetric sweat production less than 50mg, and (iii) the mean absolute change from baseline in gravimetrically measured sweat production. Patients are anticipated to be evaluated at four regular intervals. Under the Clinical Trial Agreement, Dermata and Revance will form a joint development committee to facilitate communications between the parties related to the Trial.
There can be no assurance that XYNGARITM or DMT410 will receive FDA approval for any of the foregoing indications.
Our Strategy
We plan on in-licensing, developing and commercializing differentiated medical and aesthetic dermatology product candidates for the treatment of various skin diseases and conditions, which we believe have significant unmet needs in the market. The key components of this strategy are as follows:

The dates reflected in the foregoing are estimates only, and there can be no assurances that the events included will be completed on the anticipated timeline presented, or at all. Further, there can be no assurance that we will be successful in the development of XYNGARITM or DMT410, or any other product candidate we may develop in the future, or that XYNGARITM or DMT410, or any other product candidate we may develop in the future, will receive FDA approval for any indication.
Dermatology Market Overview
We are currently focused on the medical and aesthetic dermatology markets, which include multiple common and undertreated skin diseases and conditions such as acne, psoriasis, hyperhidrosis, and multiple aesthetic skin conditions, some with no currently approved products, including the reduction of fine lines, pore size, sebum production and improvement in luminosity and overall skin quality. We believe these diseases and conditions cause significant negative impacts on patients’ quality of life, including physical and emotional trauma and social stigmatism, causing patients to constantly seek better treatment options to help improve their conditions. We also believe these markets have not experienced the same level of development and advances as other markets, as there have been few innovative topical products recently approved other than reformulations or combinations of existing compounds. We believe our product candidates will be well situated within the market and offer innovative solutions to the underserved medical and aesthetic dermatology markets.
The U.S. medical dermatology market has experienced significant growth in recent years based on the new treatment options and greater patient access to care. Based on current market data, the U.S. medical dermatology market was valued at over $8.3 billion dollars in in 2024 and estimated to be worth over $9.2 billion by 2028.
The American Society of Plastic Surgeons estimates that over 25 million minimally invasive cosmetic procedures were performed in the U.S. in 2023 of which about 9.5 million used botulinum toxin. There are many factors that continue to drive growth in the aesthetics dermatology market such as greater patient acceptance, including from younger patients, and the discretionary cash that patients are willing to spend on aesthetic skin care. We also believe patients have a growing willingness to pay out-of-pocket for effective skin treatments to achieve their desired personal aesthetic look, which further supports the demand and pricing in those markets.
Based on the foregoing, we believe the dermatology market, both aesthetic and medical, offer a low-cost commercialization opportunity compared to many other prescription-based specialty markets, due to the relatively small number of specialists in the dermatology field. According to the American Academy of Dermatology, in 2023 there were approximately 11,000 dermatologists in the U.S., and we plan to target a subset of these dermatologists, who are larger prescribers of competitive products and who treat a large percentage of patients with our approved indications. We believe the combination of prescription based and cash-pay based product lines is an attractive business opportunity, as it incorporates multiple aspects of the dermatology market that move independent of the greater healthcare market.

Background of Our Spongilla Technology
Spongilla Lacustris Overview
Spongilla lacustris, or Spongilla, is a freshwater sponge from the Spongillidea family that grows in freshwater rivers and lakes in commercial quantities in select regions of the world. It becomes dormant during the winter months and regrows each year to growth forms ranging from encrusting, to digitate, to branched, depending on its habitat’s growth conditions. While it grows in many parts of the northern hemisphere, there are only certain locations where it grows in the quantities and of the quality to viably support a commercial pharmaceutical product. One such location is the Volga River in central Russia, where we have signed an exclusive supply agreement with one of the larger known suppliers of Spongilla raw material for XYNGARITM, which we believe provides us with a reliable source of our supply of Spongilla raw material for the foreseeable future. Traditionally, locals would harvest small amounts of Spongilla for its perceived medicinal properties and use it as a folk medicine to treat a variety of inflammatory conditions, including arthritis. Over the last 22 years, our exclusive supplier has refined its harvesting methods and procedures and is now capable of supplying a high-quality raw material that meets our release criteria, year-over-year. Our supplier has the capacity to collect and process large quantities of Spongilla per year. We believe our supplier will be able to supply raw material in the quantities and of the quality necessary to support our clinical and commercial needs. Since entering into the exclusive supply agreement, we have consistently been able to order and receive quantities of raw material to support our ongoing development activities and prepare batches for filing of an NDA.
The traditional use of Spongilla in Russia has provided a large amount of safety data. In 2003, the Russian Ministry of Health indicated that Spongilla had been used by over one million people per year, with few reported safety issues. In 2017, we submitted this safety information, along with various other publications and non-clinical studies, in an Investigational New Drug, or IND, application to the FDA’s Division of Dermatology and Dental Products with reference to the FDA’s Botanical Drug Development Guidance for Industry, or Botanical Guidance. This submission enabled the FDA to approve our IND for XYNGARITM, allowing us to proceed directly into a Phase 2 clinical trial in patients due in part to this historical human exposure. In 2023, the FDA also confirmed that XYNGARITM would be filed under a NDA. While we are still required to complete certain non-clinical and pharmacokinetic studies prior to filing an NDA, we were able to strategically conserve resources while gathering human clinical efficacy and safety data prior to completing such work. We have since completed an End of Phase 2 Meeting with the FDA which provided us the approval to move into our first ongoing Phase 3 study and provided the framework necessary to file an NDA.
Spongilla’s Multiple Mechanism of Actions
The unique properties of Spongilla lacustris not only allows us to reference the FDA’s Botanical Guidance, but also helps ensure the sustainable regrowth of sufficient supply of raw material each year. While Spongilla is technically a part of the animal kingdom, it grows and acts more similarly to a plant in that it can completely regenerate every year, even in harsh environmental conditions. In addition to causing a regrowth of the sponge each year, the harsh environmental conditions in which the sponge lives help contribute to our Spongilla technologies’ multiple mechanisms of actions. Based on knowledge gained from over 22 years of harvesting Spongilla, our supplier can recognize the necessary environmental conditions and Spongilla characteristics to ensure optimal raw material harvest, maximizing the probability that the raw material contains the necessary properties for an effective pharmaceutical product. These properties include both mechanical and chemical components that are naturally occurring parts of the sponge raw material and contribute to our Spongilla technology’s mechanisms of action in the treatment of skin diseases and conditions.
The mechanical components of XYNGARITM come from the Spongilla’s skeletal structure, which is made up of siliceous spicules that are bound together by organic material, as seen in Image 2 below. These spicules are smooth, rod-like shapes which come to a point on each end, and if the Spongilla is harvested under our specified environmental conditions, the spicules can average between 150-300 micrometers in length and about 10-15 micrometers in diameter. While there are other species of freshwater and marine sponges, many of their spicules can be covered in barbs or hooks, as seen in Image 3, which we believe would get stuck in the skin or contain spicules that are blunt on each end, making skin penetration difficult.

Image 3: Sponge Spicules
After harvesting and further processing in the U.S., the form and size of our spicules make them the ideal mechanism to penetrate the stratum corneum, the skins barrier, and temporarily create a micro-channel into the dermis without penetrating subcutaneous tissue, where the larger blood vessels are located. These newly created microchannels temporarily open the skin’s barrier to allow for the targeted delivery of large and small chemical compounds into the dermis. Most topically applied products currently contain penetration enhancers that help force the active molecule through the stratum corneum and into the dermis, such as Dimethyl Sulfoxide (DMSO). However, DMSO is only able to help smaller molecules penetrate and is usually unable to aid larger molecules, such as botulinum toxin, in topical delivery. These penetration enhancers can also cause unwanted side effects such as dry skin or garlic like taste, breath, and body odor. We believe our Spongilla technology is differentiated by enabling the delivery of both small and large molecules through topical application with less irritation and side effects than other topically applied products.
In addition to creating many microchannels in the skin, we believe the penetration of the spicules can open closed comedones, allowing oxygen into the anaerobic environment of the clogged pilosebaceous glands, where C.acnes and other bacteria survive. Lastly, we believe the spicules promote collagen production within the skin which accelerates the skin’s rejuvenation period, thus bringing refreshed skin to the surface at a quicker rate than the skins normal turnover cycle. Typically, the skin takes between three to four weeks to bring a new layer to the surface, while we believe our Spongilla technology may allow this process to complete in less than one week. We believe this decreases the time to treat inflammatory skin diseases and conditions while also enhancing the look of a patient’s skin.
Our Spongilla technology also contains multiple active chemical compounds that we believe may aid in our product candidates’ treatment of multiple dermatology skin diseases and conditions. We believe part of Spongilla’s natural defense mechanism is the creation of organic material to fight off natural enemies present in the water in which it grows. This organic material binds its spicules together to form the skeletal structure of the sponge. Based on multiple in-vitro studies, we believe the organic compounds within the sponge, when separated from the spicules, have both anti-inflammatory and antimicrobial properties. We have observed anti-inflammatory activity including reduction of C. acnes, stimulated IL-8 production, and the downregulation of the production of IL-17A and IL-17F in human cell lines. Additionally, in our in-vitro studies, we observed the inhibition of lipogenesis of sebocytes, which may translate to a reduction in sebum production and oiliness of the skin in patients.
While we believe each of the mechanical or chemical components of our Spongilla technology may be beneficial in treating various diseases, we believe the impact of each mechanism may be greatly enhanced when combined with the other. The large number spicules contained in each treatment create many microchannels through the stratum corneum, allowing for sufficient penetration and delivery of the chemical components into the treatment area to fight inflammation and kill bacteria.
FDA Botanical Drug Development Guidance for Industry
Most currently approved topical dermatology products are reviewed solely by the FDA’s Office of Dermatology and Dental Products and follow a standard approval pathway. However, due to our lead product candidate, XYNGARITM, being derived from a natural source, it will be reviewed by the FDA Office of Dermatology and Dental Products with input from the FDA Botanical Review Division. While Spongilla is not a botanical, the FDA has allowed us to reference the Botanical Guidance for raw material quality control and batch to batch consistency through development and into commercialization. We believe our ability to reference the Botanical Guidance and receive input from the Botanical Review Division on XYNGARITM provides us with key advantages in XYNGARI’sTM regulatory pathway to approval, if achieved. These advantages include being able to move into human clinical studies upon the FDA’s acknowledged receipt of our IND letter and subsequent study may proceed, saving us substantial financial resources to achieve human clinical data. Additionally, while we believe that our sponge contains multiple active chemical compounds, based on our regulatory analysis of the feedback from the FDA and the Botanical Guidance, we believe we are only required to provide identifiable and quantifiable active components to show quality control and batch to batch consistency. We believe this will make it more difficult for potential competitors to replicate XYNGARITM due to their inability to know every component of our product candidate and to show their product is similar in its composition. Thus, we believe a competitor with a similar product or product candidate would have to follow all the manufacturing, development, and regulatory steps we must complete for FDA approval. However, there can be no assurance that we successfully navigate the development of XYNGARITM or that XYNGARITM will receive FDA approval.

Our Product Candidates
XYNGARITM
Our lead product candidate, XYNGARITM, is a unique, once weekly, naturally derived topical product, first being developed for the treatment of moderate-to-severe acne, or acne. It is derived from freshwater Spongilla lacustris, or Spongilla, which grows under certain environmental conditions in select locations throughout the northern hemisphere. Our Spongilla raw materialis harvested by our exclusive partner in Russia abiding by strict protocols based on our supplier’s 22 years of experience and our expertise in an ideal pharmaceutical product. The result of these strict protocols is a consistent chemical structure that is reproducible year after year, which is critical in producing a material able to be used in a pharmaceutical product. After harvesting, the Spongilla is shipped to our manufacturing facility in the U.S. for further processing into a uniform powder before being packaged into sachets. Immediately prior to treatment the patient will mix the powder with a diluent (hydrogen peroxide) to form a paste, which the patient can then apply to the treatment area to treat the multiple facets of their disease. XYNGARITM utilizes the Spongilla’s mechanical spicules to help resurface a patient’s skin while also creating microchannels through the stratum corneum to allow the penetration of the Spongilla’s naturally created organic compounds to help treat various skin diseases. We believe these organic compounds can travel through the newly created microchannels into the dermis and sebaceous glands where both inflammatory and non-inflammatory acne lesions originate. XYNGARITM targets treatment of the multiple facets of acne by combining the substantial mechanical and chemical activity of Spongilla into an easy to apply product that only needs to be applied once weekly. If approved by the FDA, we believe the combination of the mechanical and chemical properties of XYNGARITM has the potential for a more rapid time to treatment effect with fewer treatments, less side effects, and better tolerability than other currently marketed topical acne products.
XYNGARITM for Treatment of Acne
Market Opportunity. Acne is characterized by areas of scaly red skin, non-inflammatory blackheads and whiteheads, inflammatory lesions, papules, and pustules and occasionally cysts and scarring that occur on the face, neck, chest, back, shoulders, and upper arms. It affects approximately 50 million people in the U.S., with an estimated 32.6 million diagnosed cases in the U.S. in 2023, with about 85% of teenagers in the U.S. experiencing some form of acne. The U.S. prescription acne market had approximately $2.6 billion in prescription pharmaceutical sales in 2016 and is expected to reach approximately $3.8 billion in 2026 according to GlobalData Inc. market data.
Most patients experience some form of acne during their teenage years and for some, their acne may diminish over time, or at least tends to decrease by age 25. There is, however, no way to predict how long it will take for acne to disappear entirely, with some individuals suffering from acne well into their 30s, 40s and beyond. While not life-threatening, acne causes significant trauma for those suffering from it due to social stigmas, substantial risk of permanent facial scarring, lowered self-esteem and social withdrawal. Therefore, we believe early and aggressive treatment with an effective, once weekly, topical product may lessen the overall long-term impact of this disease and may lead to an increase in a patient’s quality of life.
Due to acne’s negative impact on a patient’s quality of life and negative impact on facial aesthetic, patients suffering from acne tend to be highly motivated to treat their acne and we believe willing to pay more out-of-pocket for higher priced and highly effective treatment, like XYNGARITM. It is our belief that patients seeking an easy to use and effective topical product will tolerate less favorable reimbursement rates than for other prescription products for other indications, allowing for favorable pricing if we are able to eventually obtain approval for and successfully commercialize XYNGARITM for acne. Furthermore, if approved, we believe that XYNGARITM natural characteristics may allow us to expand our addressable acne market to include those patients who value using naturally derived products, such as XYNGARITM.

The acne market can be broken into three separate classes based on the severity of the acne:
Limitations of Current Standard of Care. While current treatment options may be effective for some patients, there are many limitations and drawbacks of current acne products which cause poor patient compliance. All currently approved topical therapies for the treatment of acne must be applied once or twice a day to allow an accumulation of the active ingredient within the skin to effectively treat the disease. This requirement to apply multiple times per day becomes very onerous and time consuming for patients, causing many patients to fail to comply with the strict application regimen and/or skip multiple treatments. Proper use and application schedules are particularly important for topical acne products and poor patient adherence may lead to reduced treatment effect and ultimately discontinuation of treatment by the patient due to the lack of effect.
Many current acne products, such as retinoids that must be applied at least once or twice-a-day, may cause significant stinging, burning, and peeling after each application. These tolerability issues, which may start occurring after the first application, and the substantial discomfort they cause, lead many patients to discontinue the necessary daily application schedule or the use of the product altogether. It is well known that benzoyl peroxide, or BPO, leads to drying of the skin and that retinoids result in many local skin reactions including erythema, burning, and peeling, after the first treatment. It has been observed in the combination study of adapalene/BPO, where more than 20% of the subjects reported moderate or severe erythema and stinging/burning.
Lastly, most topical products have an unavoidable latency period of 6-8 weeks until patients have a definite improvement in their acne lesions. This means they may have to endure 30 to 60 applications before observing that their acne is improving (assuming a daily, or twice daily regimen), all while dealing with the burning, stinging, and peeling that may accompany these topical products. We believe that teenagers, who make up the largest segment of the acne market, become impatient with the lack of rapid perceived effect leading to premature discontinuation of treatment. The lack of rapid treatment effect, side effects, and onerous application schedules all greatly contribute to patient noncompliance issues and could ultimately lead to treatment failure for current topical therapies. We believe patients are more concerned with rapid efficacy outcomes and low side effects than costs, thus we believe patients will be more willing to pay higher out of pocket costs for a product that has these attributes.
Our Solution for Moderate-to-Severe Acne. If approved, we believe XYNGARI’sTM once weekly application regimen and apparent rapid treatment effect will increase patient compliance, potentially increasing the likelihood of improved acne results. Using our multifaceted, once weekly Spongilla treatment technology, we are developing XYNGARITM to create a paradigm shift in how acne is treated by dermatologists by attempting to make XYNGARITM the preferred treatment option for all acne patients. We have designed XYNGARITM to treat the multiple factors of acne while also attempting to increase patient compliance through ease of use and acceptable tolerability profile.
If approved, we believe XYNGARITM has the potential to remedy many of the negative characteristics associated with current topical therapies for moderate-to-severe acne, including cumbersome treatment regimens, negative side effects (including burning, stinging, itching or dryness, which may occur as early as the first treatment and continue daily thereafter), and delayed time to effectiveness (which may take up to eight weeks). XYNGARITM is designed to be applied only once a week, rather than once or twice a day. We believe a once weekly schedule may be conducive to high patient compliance as it is less onerous for the patient. In addition, in our Phase 2b acne trial, on average, patients experienced an approximately 45% reduction in inflammatory acne lesions after just four treatments, with continued improvement of up to 62% reduction of inflammatory lesions at 12 weeks. Further, approximately 90% of patients had no, or mild, tolerability issues at the end of the 12-week trial and no patients experienced any severe tolerability issues.
Table of Contents
In addition, in our Phase 2b trial we observed that XYNGARITM started showing a statistically significant difference from placebo for all three endpoints after just four treatments while also having a rapid reduction on inflammatory and non-inflammatory lesions. We believe this rapid visible response encouraged patients to continue to comply with the once weekly application schedule leading to a continued reduction in their lesions until the end of trial at week 12. Thus, we believe that a topical product that only needs to be applied once weekly with a quicker time to perceived treatment effect and fewer tolerability issues may result in greater treatment success due to improved patient compliance leading to loyal and repeat users.
XYNGARITM for the Treatment of Mild-to-Moderate Psoriasis
We believe that XYNGARITM could also be an effective treatment for mild-to-moderate psoriasis based on the clinical data received from our Phase 1b POC trial and the in-vitro effect XYNGARITM has shown on the down regulation of IL-17A and IL-17F, as well as its ease of application to mild-to-moderate psoriatic lesions with smaller surface areas.
Psoriasis is characterized by “plaques,” or raised red areas of skin covered with a silver or white layer of dead skin cells referred to as “scales.” Psoriatic plaques can appear on any area of the body, but most often appear on the scalp, knees, elbows, trunk, and limbs, and the plaques are often itchy and sometimes painful. The psoriasis lesions are characterized by hyperproliferation of keratinocytes and a lymphocyte-rich infiltrate consisting primarily of T cells. In the dermis and epidermis, T lymphocytes interact with antigen-presenting cells and secrete Th1 and Th17 cytokines. These activated T cells and the inflammatory cytokines they secrete are believed to induce the skin lesions seen in psoriasis. In addition to the broad anti-inflammatory properties, we have observed in our clinical acne studies, XYNGARI’sTM ability exhibited in-vitro a dose dependent inhibition of both IL-17A and IL-17F, key cytokines implicated in the pathogenesis of psoriasis. Thus, XYNGARITM may provide a method to topically deliver targeted anti-inflammatory therapy directly to psoriatic lesions with good local tolerability in an easy to apply regimen.
Market Opportunity. Currently patients with mild-to-moderate disease are either underdiagnosed, undertreated or untreated. This leaves patients seeking new and effective treatment options. Psoriasis is a chronic, inflammatory skin disorder estimated to affect up to 3.2% of the world’s population with global sales of $14.2 billion in 2020, which is projected to increase to $27.5 billion by 2030. Plaque-type psoriasis is the most common form of psoriasis, occurring in more than 80-90% of cases of psoriasis with approximately 80% of patients experiencing the mild disease form and 20% experiencing moderate-to-severe form of the disease. In addition to the disfigurement caused by psoriatic lesions, patients also may experience pruritus, or itching, which can be particularly common and bothersome for patients. Not only does psoriasis cause direct clinical challenges, but patients also suffer a negative impact on their quality of life. Patients can suffer substantial psychological impacts from their disease, including, social stigmas, feelings of rejections and shame, discrimination in the workplace, and reduced productivity, among many others. These patients are commonly looking for a safe and effective product to treat their disease.
Limitations of Current Standard of Care. Most of the available therapies target moderate-to-severe disease, meaning that mild patients are undertreated with one in five not being happy with their current treatments. The treatments for mild psoriasis patients are mostly generic but are often inadequate to control a patient’s disease. Mild psoriasis patients are first treated with topical therapies, like Vtama, Zoryve, Opzelure, and Eucrisa, due to the reduced systemic exposure. However, patients often feel that topical treatments are one of the negative aspects of psoriasis, which we believe is partly due to the limited options available like, coal tar, retinoids, calcineurin inhibitors and corticosteroids. While topical steroids are a very common treatment, drawbacks include being able to be used only for a short period of time and are associated with Hypothalamic pituitary adrena axis suppression, skin atrophy (thinning), striae (stretch marks), and telangiectasia (spider veins), among other side effects. Furthermore, some of these side effects are irreversible, persisting even after therapy is discontinued. Consequently, high-potency topical steroids are not recommended for chronic use and physicians generally will not prescribe them for treatment on the face. Also, rebound is a known challenge with steroids, where after steroid discontinuation, the psoriasis returns even worse than it was before steroid treatment was initiated.

While biologic therapies, including drugs such as Enbrel, Cosentyx, Humira, and Stelara, are available for treatment of psoriasis, their use remains highly restricted to patients with moderate-to-severe disease. In the U.S., with less than 20% of patients having moderate-to-severe psoriasis, we believe a vast majority of the psoriasis market are left without long-term effective treatment options. While additional data has caused an uptake of biologics, they remain limited due to multiple factors, including being indicated only for use in moderate-to-severe patients, high costs, consequent reimbursement and access restrictions, frequent high patient co-pays, perceived risk of side effects, and patient fear of injection. Additionally, we believe there is room for topical products that treat mild psoriasis to be priced at a premium compared to other topical products for other inflammatory skin diseases like acne. This is based on fact that when comparing the cost of biologic therapy, which can cost $50,000 per year, an effective and safe topical product for mild psoriasis could have a large impact on the market. Therefore, we believe physicians would be more likely to prescribe a topical product for psoriasis long before biologic treatment, and patients experiencing milder psoriasis would prefer using a topical product over a systemic treatment.
Non-biologic systemic therapy options for psoriasis exist, but their use is also limited due to unfavorable side effects. Apremilast (Otezla), an oral PDE4 inhibitor, generated more than $1 billion in sales in all indications in 2019, but has only achieved a small patient share in psoriasis due to limitations on its use to moderate-to-severe patients, its modest symptomatic improvement, and frequent adverse events. We believe there is still a great need to bring to market a product that addresses mild-to-moderate psoriasis.
Due to the shortcomings of existing topical therapies and the lack of options providing robust symptomatic improvement with chronic treatment, especially in the last 25 years, we believe there remains a need for a safe, effective, and easily applicable topical treatment for chronic disease, that has a low risk of side effects, is well tolerated, and can be easily applied on all anatomical areas.
Our solution for Mild-to-Moderate Psoriasis. Similar to the needs of patients with acne, we believe patients suffering with psoriasis might comply better with a treatment that is easy to apply and requires less application time than current treatment options. XYNGARITM, if approved, could be used as a first line therapy for patients with mild-to-moderate psoriasis. We believe the spicules within XYNGARITM will help break up the psoriatic lesions, while the anti-inflammatory components of XYNGARITM assist with the healing of the lesions. Due to the historical use of Spongilla and the human safety data collected to date in our clinical studies, we believe XYNGARITM may be suitable for long term treatment of chronic psoriasis due to its unique treatment effect and acceptable safety and tolerability profile.
In addition to the mechanical effects of XYNGARITM, extracts of the organic material have shown in-vitro to have a dose dependent inhibition of IL-17A and IL-17F secretion. In the dermis and epidermis, T lymphocytes interact with antigen-presenting cells and secrete Th1 and Th17 cytokines, including interferon-gamma (IFN-g), interleukin (IL)-2, IL-17, IL-22, and tumor necrosis factor alpha (TNF-α). These activated T cells and the inflammatory cytokines they secrete are believed to induce the skin lesions seen in psoriasis and be a fundamental contributor in the disease’s immune pathway. We know that there are multiple approved IL-17A inhibitors on the market, such as secukinumab (Cosentyx®, Novartis) and ixekizumab (Taltz®, Eli Lilly and Co.), but these are both biologics and only indicated for patients with moderate-to-severe psoriasis who are candidates for systemic therapy. The limited patient population who are candidates for these biologic treatments is a small percentage of the overall psoriasis market. Therefore, a topical product that can inhibit the IL-17 pathway in the skin with minimal systemic exposure would be an ideal option for both physicians and patients.
Based on clinical and non-clinical data generated to date for XYNGARITM, and anecdotal evidence of XYNGARITM ’s effect on psoriatic lesions, we completed a Phase 1b, open label, POC study in mild-to-moderate psoriasis patients in October 2021. This trial included once weekly treatments of XYNGARITM for 12 weeks in 30 mild-to-moderate psoriasis patients with lesions covering 2% to 30% of their body surface area. The primary endpoints in this trial were the Physician’s Global Assessment, which is a 6-point scale measuring the physician’s assessment of psoriasis severity of the target lesion site, the Psoriasis Area Severity Index scale is also a 6-point scale measuring the psoriatic disease severity taking into account qualitative lesion characteristics (erythema, thickness, and scaling) and degree of surface area involvement and the Pruritus Visual Analog Scale consists of the patient’s measurement of pruritus, or itch, in addition to normal tolerability and safety assessments. We announced top-line results in October 2021, and based on the efficacy, safety and tolerability profile seen in the POC trial we initiated additional work to better inform the clinical trial design prior to moving into a larger Phase 2, placebo-controlled, clinical trial upon the receipt of sufficient financial resources.
DMT400 for the Topical Delivery of Macromolecules
DMT400 is our treatment regimen that utilizes the unique mechanical features of our Spongilla technology to facilitate the intradermal delivery of macromolecules, such as botulinum toxin, monoclonal antibodies, dermal fillers, or vaccines, by topical application rather than with injections. These macromolecules are highly effective and approved for the treatment of multiple medical and aesthetic skin conditions and diseases, but currently are not approved in a topical form because the molecular structures are too large to penetrate the stratum corneum, the skin’s outermost defense barrier. Thus, all current macromolecule treatment options for skin conditions and diseases must be injected, either intramuscularly or intradermally, sometimes requiring numerous injections. We believe that DMT400’s topical application regimen may provide patients with a topical treatment option for both medical and aesthetic dermatology conditions using products previously unavailable to them in a topical treatment.
Table of Contents
Image 4: Siliceous Spicules Microchannels
DMT400 works by first topically applying our proprietary sponge powder to the treatment area wherein the mechanical spicules of the sponge penetrate the skin, thereby creating microchannels into the dermis as seen in Image 4 above. Unlike a derma roller or other microneedle technology, our unique spicules remain in the skin for one to two days allowing the microchannel to remain open rather than close up, as they would after using a derma roller. With the microchannel open for a longer period a macromolecule can be applied topically to the skin and is thus able to penetrate into the dermis. We believe this topical application of a macromolecule can be massaged into the newly created microchannels thereby facilitating the delivery of the macromolecule, through the microchannel and into the dermis, without the need for injections. This targeted delivery to the dermis rather than delivery to the systemic circulation, may decrease the systemic spread of these macromolecules thus potentially reducing side effects seen with injections, while increasing targeted application to where the disease resides.
DMT410 for the Treatment of Primary Axillary Hyperhidrosis
We initially tested our DMT400 treatment with our DMT410 program, which consists of a topical application of our proprietary sponge powder followed by a topical application of botulinum toxin, a macromolecule. DMT410 was initially tested in a Phase 1b POC trial of ten (10) patients with primary axillary hyperhidrosis to determine if our sponge powder could successfully facilitate the intradermal delivery of botulinum toxin and potentially other macromolecules. Based on the results seen from this study we believe we were successful in delivering active botulinum toxin to the dermis for the treatment of primary axillary hyperhidrosis and potentially other skin conditions.
Market Opportunity. Hyperhidrosis is a life-altering disorder of excessive sweating out of proportion with thermoregulatory requirements. While many patients may exhibit this excessive sweating in response to specific triggers, such as emotional stress, others may exhibit symptoms spontaneously. Typically, the diagnosis of hyperhidrosis is based partly on subjective measures that measure how the excessive sweating affects a patient’s quality of life. Physicians also gravimetrically measure the amount of sweat produced, though there is no standardized threshold which defines hyperhidrosis. It is believed to affect an estimated 15 million people in the U.S. alone. The U.S. prescription hyperhidrosis market had approximately $66 million in prescription pharmaceutical sales in 2020, and is expected to reach approximately $282 million in 2030, with almost 40% from injections of BOTOX, according to GlobalData Inc. market data. According to a 2016 update on the prevalence and severity of hyperhidrosis in the U.S., axillary (underarm) hyperhidrosis, is the most common form of the disorder. However, patients are affected by other forms like palmar (hands) and plantar (feet) hyperhidrosis, which we believe DMT410 may be able to treat and avoid the side effects seen in studies of poor administration of intradermal injections.
Table of Contents
Limitations of Current Standards of Care. While the prevalence of hyperhidrosis is significant, treatment options are limited, and many come with unwanted side effects making patient acceptance low. Typical first line therapy is usually with aluminum chloride-based antiperspirants, but many have potential drawbacks. First, daily applications can be time consuming leading to poor compliance among patients. Second, many antiperspirants are irritating to the skin leading to treatment discontinuation. Lastly, topical aluminum chloride treatment has a transient duration of effect and requires frequent reapplication to maintain sweat control. More recently, topical anticholinergics have been investigated and approved, such as Botanix Inc. (formerly developed by Fresh Tracks, Inc.) and Journey Medical Corporation (formerly developed by Dermira, Inc.), but we believe they tend to have the same side effects as systemic anticholinergics which are used off-label. These side effects include dry mouth, dry eyes, blurred vision, headache, urinary retention, among others. The unwanted side effects are often so intolerable that up to one third of patients are forced to withdraw from treatment. If topical or systemic treatments fail, then patients can get intradermal injections of botulinum toxin which has been shown to have a great treatment effect, but treatment is very technique driven, requiring a trained physician to administer the toxin to the thin layer of the dermis. Many times, poor treatment response with botulinum toxin is due to incorrect or insufficient dosing or incorrect administration. Patients may also experience injection site pain or discomfort, which may be accompanied by swelling and bruising. However, for the treatment of palmar hyperhidrosis with intradermal injections of botulinum toxin, the most notable adverse event is transient hand weakness, if administered incorrectly. As a last resort, patients may also seek surgery to treat their hyperhidrosis, if less invasive treatment options fail. While there are treatment options available for hyperhidrosis patients, only about half of affected individuals seek treatment due to social embarrassment associated with the diagnosis of the disease. We believe this leaves a wide gap in the market for a product that combines the efficacy of botulinum toxin with the safety and tolerability profile of topical therapies. We believe DMT410, if successfully commercialized, could address this underserved market opportunity.
Our Solution for Primary Axillary Hyperhidrosis. While primary axillary hyperhidrosis is idiopathic, the mechanism is thought to be neurogenic overactivity of the eccrine (sweat) glands in the affected area. Based on the summary basis for approval of BOTOX, we know that botulinum toxin type A has a clinical effect on hyperhidrosis, which acts by disrupting sympathetic stimulation to the eccrine glands resulting in considerably reduced axillary sweating from four to 12 months. Based on the package insert for BOTOX, intradermal injections of 50 units of BOTOX saw a greater than 50% decrease in axillary sweat production in 81% and 41% of patients treated with BOTOX or placebo, respectively, at four weeks. While intradermal injections of botulinum toxin appear to be very effective, the treatment requires multiple injections into each axilla, which is time consuming for the treating physician and administration is very technique sensitive due to the thin nature of the dermis. Additionally, given the nature of the target tissue being more sensitive, and the number of injections required, it is believed that injection site pain is a major cause for the lack of compliance. Thus, we believe a topical application regimen, capable of penetrating the stratum corneum to deliver botulinum toxin into the dermis, may be able to exhibit similar efficacy with greater compliance and adoption. In a Phase 1b POC study of DMT410 for the treatment of axillary hyperhidrosis, we saw a greater than 50% decrease in axillary sweat production in 80% of patients at week four. This result supports our belief that topical application of botulinum toxin via our Spongilla technology to the dermis could be a viable alternative to intradermal injections. If approved, DMT410 could eliminate the need for intradermal injections of botulinum toxin. Therefore, we believe DMT410 could potentially be a favorable treatment option for patients suffering with primary axillary hyperhidrosis. Additionally, we also believe that DMT410 may be an effective treatment for palmar or plantar hyperhidrosis due to DMT410’s delivery of botulinum toxin to the dermis without the risk of distance spread of toxin to the muscle as with intradermal injections of botulinum toxin. DMT410 could limit the side effects seen with intradermal injections including hand weakness and administration pain. There can be no assurance that DMT410 will receive FDA approval for hyperhidrosis.
DMT410 for the Treatment of Aesthetic Conditions In addition to the use of DMT410 in the treatment of hyperhidrosis and other medical dermatology conditions such as acne, based on the data from our recent Phase 1b POC trial of DMT410 for the treatment of multiple aesthetic skin conditions such as pore size, sebum production, fine lines, luminosity, and brightness of the skin, we believe DMT410 has an opportunity to be used for the treatment of multiple aesthetic skin conditions. Botulinum toxin is known to treat a variety of aesthetic skin conditions, but to achieve these positive effects, the botulinum toxin needs to be delivered to the dermis rather than the muscle to have the desired effect. DMT410’s uniquely sized spicules create microchannels through the stratum corneum and into the dermis that are large enough for botulinum toxin to be delivered to the dermis. However, the spicules are not long enough to reach the muscle layer, which limits the potential distant spread of toxin and potential side effects. Botulinum toxin acts by blocking the release of acetylcholine into the synaptic cleft, where it binds to a cholinergic receptor, thereby inhibiting sympathetic nerve function. This ability to inhibit cholinergic transmission makes it useful to treat indications with glandular hypersecretion, like sebum production or hyperhidrosis, which are partly caused by hyperactive sympathetic nerves. For aesthetic indications, since botulinum toxin must be delivered to the dermis, intradermal injections are typically required but can require numerous injections in order to cover the larger surface area to treat these aesthetic skin conditions as compared to targeted injections to the muscle. Intradermal injections can also be difficult to effectively administer and may be painful for patients. This tends to lead to poor adoption of this therapy, which is why we believe there are currently no approved aesthetic indications utilizing intradermal injections. Additionally, no topical formulations of a botulinum toxin have been approved, likely due to the size of the molecule and its difficulty in penetrating the stratum corneum to reach the dermis. Therefore, with no currently approved intradermal injections or topical applications methods of botulinum toxin for aesthetic skin conditions, we believe there is a large market opportunity for a product that can successfully deliver botulinum toxin by topical application into the dermis to improve a patient’s aesthetic appearance. If approved, we believe DMT410 can address this market.

Limitations of Standards of Care While injections of botulinum toxin into the muscles have been approved for many years for aesthetic treatments such as the reduction of glabellar, lateral canthal or forehead lines, there are many other aesthetic skin conditions, such as enlarged pore size, excess sebum production, fine lines, decreased luminosity, and decreased brightness that botulinum toxin has been demonstrated to improve but a botulinum toxin product, whether via intradermal injections or topical application, has yet to be approved for these indications. This may be because these aesthetic indications typically require botulinum toxin to be delivered to the dermis rather than the muscle, which due to the thin nature of the dermis, can be more difficult than injecting into the muscle. Additionally, the areas of the face requiring intradermal injections are much more sensitive and thus can be more painful for patients. These intradermal aesthetic indications typically require a wider dispersion of botulinum toxin to be delivered to the dermis rather than the few injections into the muscle needed for the deeper facial lines. Some intradermal studies have required 25-30 intradermal injections in the face to deliver sufficient quantities of botulinum toxin to the dermis. With some patients having a fear of needles, a treatment that can avoid the use of needles would be desirable for this population. Additionally, topical application of botulinum toxin has been difficult due to the size of the molecule making it difficult for the botulinum toxin to penetrate the stratum corneum, resulting in many topical applications being ineffective and discontinued. An example is Revance’s RT001 product which did not achieve the primary or other secondary endpoints in a Phase 3 trial for the treatment of crow’s feet and therefore, Revance does not plan to continue development of this program at this time. Another botulinum toxin company, Allergan (now part of AbbVie), purchased a company in 2016 to pursue development of a topical botulinum toxin program. However, we believe Allergan has not conducted any studies with this program. We believe most botulinum toxin companies remain interested in developing a topical means of administering botulinum toxin that is less painful, easy to apply, provides wider coverage of toxin, and limits potential distant spread of toxin, but no product has yet been successfully developed.
Our Solution for the Treatment of Aesthetic Skin Conditions We believe a product candidate like DMT410, which may be able to successfully deliver botulinum toxin to the dermis covering a larger facial area than injections, would provide a new treatment option for a variety of aesthetic skin conditions, such as reduction in pore size, sebum production, and fine lines, and improvement in skin luminosity and brightness, thus potentially expanding the market for uses of botulinum toxin beyond injections into the muscle for treatment of deep lines. We believe DMT410 may be able to provide patients with a topical treatment option without the pain and discomfort typically associated with injections of botulinum toxin. Additionally, we believe administration will be easier and less time consuming for dermatologist, making it an additional value driven treatment option they can offer. While current botulinum toxins are approved for injections into the facial muscles to treat deeper wrinkles such as glabellar lines, lateral canthal lines and forehead lines, there remain many other aesthetic conditions of the face which could greatly benefit from an intradermal administration of botulinum toxin, especially via topical application. Certain aesthetic indications such as reduction in fine lines, pore size, and sebum production, and improvement in luminosity and brightness are typically not treated with injections into the muscles but need botulinum toxin to be delivered to the dermis to have the proper effect. With DMT410’s uniquely sized spicules, we believe it can create numerous microchannels into the dermis allowing a pathway for the topical application of botulinum toxin. Once in the dermis botulinum toxin is able to act on reducing sebum production which in turn may reduce pore size and overall oiliness of the skin. Additionally, botulinum toxin has been demonstrated to have a beneficial effect on the mean volume and depth of facial lines giving the skin a smoother appearance. Therefore, we believe there may be a need for a product, such as DMT410, that can facilitate the topical application of botulinum toxin into the dermis, to treat a variety of these aesthetic skin conditions.
If approved, we believe DMT410 has the potential to expand the market for botulinum toxins’ treatment to multiple additional aesthetic skin conditions. We believe DMT410 can be an effective product at delivering bioactive botulinum toxin with a topical application for treatment of pore size, sebum production, fine lines, luminosity, brightness, overall aesthetic appearance and possibly more. We recently completed a Phase 1b POC trial of DMT410 for the treatment of multiple aesthetic skin conditions where we examined improvements in pore size, sebum product, luminosity, brightness, and Global Aesthetic improvement after one treatment of DMT410. We believe this POC trial produced data which demonstrated that DMT410 was able to deliver botulinum toxin to the dermis and showed a reduction in pore size, reduce sebum production, improved luminosity, improved brightness, and improved the patients’ Global Aesthetics. This study also produced no adverse events and provided acceptable tolerability data with only mild tolerability effects seen fifteen (15) minutes post treatment. We believe this data warrants further development of this program and we are currently seeking a partner who has a botulinum toxin they are looking to develop for aesthetic skin conditions which require delivery of botulinum toxin to the dermis. There can be no assurance that DMT410 will receive FDA approval for any aesthetic indication or that we will be able to find a partner for development.

Clinical Progress of our Lead Product Candidates
XYNGARITM Phase 3 Clinical Trial Program for Acne
In December 2023, we initiated the XYNGARITM Phase 3 clinical program entitled Spongilla Treatment of Acne Research study (STAR). The XYNGARITM Phase 3 clinical program will include two Phase 3 clinical trials to evaluate the efficacy, safety, and tolerability of XYNGARITM in patients with moderate-to-severe facial acne. Each Phase 3 trial will be randomized (2:1), double-blind, placebo-controlled, and will enroll approximately 500-600 patients with moderate-to-severe acne, ages 9 years and older in the United States and Latin America. The primary endpoints are the mean change from baseline in inflammatory and noninflammatory lesion counts and the Investigator Global Assessment (IGA) treatment response rate. IGA is measured on a 5-point scale (0-4), with a treatment response defined as at least a 2-point improvement from baseline and an IGA score of 0 (clear) or 1 (almost clear). Patients will be treated once a week for 12 weeks with either XYNGARITM or placebo and will be evaluated monthly. STAR-1 is the first of two pivotal Phase 3 trials, with top-line results expected in March of 2025. Upon adequate financing, we intend to initiate the second Phase 3 clinical trial, STAR-2, which we expect will be followed by a long-term extension study as required by FDA. If positive, the results from the Phase 3 program will be used to support the filing of an NDA with FDA.
XYNGARITM Phase 2b Clinical Results for Acne
In June 2020, we received results from our randomized, double-blind, placebo-controlled, Phase 2b clinical trial of once weekly treatments for twelve weeks of XYNGARITM for acne. We enrolled 181 moderate-to-severe acne patients at fourteen (14) sites across the U.S. Patients were required to be 12 years of age or older, have at least twenty (20) non-inflammatory lesions, twenty (20) inflammatory lesions, no more than two (2) nodules or cysts and be a moderate or severe (meaning a 3 or 4) on the IGA scale of acne. The IGA scale consists of a 5-point scale, 0-4, with 0 being clear, 1 being almost clear and 4 being severe acne as graded by the treating physician. Patients were randomly divided into two treatment groups, either to receive XYNGARITM or placebo. Patients were required to apply the product, whether XYNGARITM or placebo, to the entire face, once weekly for 12 weeks with the first two weeks of treatment applied in office under the supervision of trained study staff, then the remaining 10 weekly treatments were applied at home by the patient.
The primary clinical endpoints of the trial included the absolute reduction in inflammatory lesions from baseline. The secondary clinical endpoints included:
· the absolute reduction in non-inflammatory lesions from baseline;
· safety and tolerability.
All statistical analyses and data shown for our Phase 2b study are on the intent-to-treat, or ITT, population. The ITT population included all randomized subjects in the group to which they were randomized, regardless of study drug received or if they completed the study. The ITT approach provides an unbiased comparison among the treatment groups.
Table of Contents
The trial was completed in June 2020 and showed a statistically significant and we believe, a clinically meaningful effect for all efficacy endpoints of the trial, namely reduction in inflammatory and non-inflammatory lesions and IGA responders. Notably, the treatment effect for all efficacy endpoints was statistically significant at the four-week mark, after only four treatments, and continued to be statistically significant for week eight and week 12 when compared with placebo. Patients saw a rapid and sustained therapeutics treatment effect in percentage change in inflammatory lesions with a 45% reduction in inflammatory lesions at week four and reached 62% reduction in inflammatory lesions at week 12 compared to 24% and 42% reduction of inflammatory lesions for placebo at weeks four and 12, respectively. The effect on non-inflammatory lesions were also statistically significant after four weeks, with the therapeutic effect of an approximately 36% reduction in non-inflammatory lesions at week four reaching a therapeutic effect of 58% at 12 weeks, which was statistically significant when compared with placebo. In addition, both inflammatory and non-inflammatory percent reduction in lesion counts had P-values of less than 0.001 at week four and week 12 when compared to placebo.
We also saw an early statistically significant separation in IGA with 15% of patients in the XYNGARITM group considered responders on the IGA scale, or who had an IGA score of 0, “clear,” or 1, “almost clear,” after only 4 treatments as compared with just over 2% of patients on placebo. This statistical separation continued for the remainder of the trial where at the completion of the trial, or week 12, 44% of patients in the XYNGARITM group, compared with 17% in the placebo group were IGA responders. This difference was statistically significant with a P-value of less than 0.001.
No reported drug-related severe adverse events were reported in the trial. The drug also appeared to be tolerable by a majority of patients with greater than 92% of patients experiencing no or mild tolerability with no severe dryness, scaling, erythema, or burning/stinging reported at week 12. Of those patients who did report tolerability issues, they also reported that the issues were usually transient and resolved quickly without intervention. Based on this data, after holding an End of Phase 2 Meeting with FDA, we initiated the Phase 3 program in moderate-to-severe acne with the same clinical endpoints and the same formulation of XYNGARITM.
The following diagrams and tables show the absolute reduction of inflammatory and non-inflammatory lesions from baseline until the end of study, or week 12, for both XYNGARITM and placebo (Image 5), and percent reduction of inflammatory and non-inflammatory lesions from baseline until end of study, or week 12, for both XYNGARITM and Placebo (Image 6). Although reduction in non-inflammatory lesions was a secondary endpoint of this trial, it is a required metric for the Phase 3 acne studies necessary for FDA approval.

Additionally, the safety and tolerability profile of XYNGARITM appeared to be acceptable with a small number of patients experiencing treatment emergent adverse events as seen in Image 8 below. In this Phase 2b trial, no subject receiving treatment with XYNGARITM experienced a severe local skin reaction at study end nor did any patient undergo a dose modification. Most tolerability issues were mild and resolved shortly after application without any rescue medication as seen in Image 8 below. Overall, XYNGARITM was generally safe and well tolerated by patients when applied once weekly for 12 weeks.

XYNGARITM Phase 2a Clinical Results for Acne
In 2018 we conducted the first clinical trial of XYNGARITM, a randomized, double-blind, 2x2 factorial, placebo-controlled, Phase 2a clinical trial of XYNGARITM for the treatment of acne. We enrolled 121 patients to evaluate the tolerability, safety, and efficacy of DM XYNGARITM T310 mixed with 3% H2O2 following 12 weeks of topical administration in male and female patients with moderate-to-severe facial acne. The study employed a 2x2 factorial design to assess the contribution of each component of the investigational product (i.e., Spongilla lacustris topical powder and 3% H2O2 USP). This Phase 2a clinical trial employed the same clinical endpoints as our Phase 2b clinical trial of XYNGARITM for the treatment of acne, as discussed above.
Patients were randomly divided into one of four treatment groups, XYNGARITM + 3% H2O2, XYNGARITM + Water, Placebo + 3% H2O2, or Placebo + Water (control). The patients were required to apply the assigned study drug to their entire face up to once weekly for 12 weeks (84 days), beginning on Day 1 and through Day 78 (as applicable). During study center visits on Days 29 and 57, a determination was made for each patient, based on the Investigator’s Global Assessment (IGA) score, as to whether study drug application would continue once weekly or at a lower biweekly frequency (once every 2 weeks). Specifically, patients with an IGA > 1 at the Day 29 or Day 57 visits continued with once weekly study drug applications, while patients with an IGA 1 at these same visits were instructed to subsequently apply their assigned study drug biweekly (see Image 10 below for a presentation of the study drug application frequency algorithm).

Image 10. Application Frequency Algorithm by Study Visit
This Phase 2a trial showed statistically significant and clinically meaningful effects for its endpoint, absolute reduction in inflammatory lesions when comparing XYNGARITM + 3% H2O2 and placebo + water (control) groups at both week 8 and week 12 or end of study. At week 12, XYNGARITM + 3% H2O2 had a 16-lesion reduction from baseline while placebo + water had an 11 lesion reduction from baseline, with a p-value of less than 0.05. Across all the treatment groups, there was a mean decrease from baseline (i.e., improvement) in the inflammatory and non-inflammatory lesion counts at Days 15, 29, 57, and 85. However, there were no statistically significant differences between the XYNGARITM + 3% H2O2 group versus the placebo + water (control) group for the mean changes from baseline in non-inflammatory lesion counts.
We did not observe a statistically significant difference between the XYNGARITM + 3% H2O2 group and the placebo + water (control) group in the percentages of patients with IGA treatment success (IGA score of 1 or 0 and a 2-grade change) or patients with 1-grade or 2-grade improvements from baseline in IGA at any visit. At Day 85 in the XYNGARITM + 3% H2O2, XYNGARITM + water, placebo + 3% H2O2, and placebo + water groups, 29.6%, 20.0%, 27.6%, and 34.5% of patients had IGA treatment responders, respectively; 66.7%, 66.7%, 65.5%, and 55.2% of subjects had a 1-grade improvement from baseline in the IGA, respectively; and 37.0%, 20.0%, 27.6%, and 34.5% of subjects had a 2-grade improvement from baseline in the IGA, respectively.
Analysis of Placebo: After speaking with the clinical investigators in the trial, it was determined that the higher than normal placebo response in non-inflammatory lesions may have been partially due to the stickiness of the placebo, which required patient to scrub their face, resulting in exfoliation of the skin and removal of sebaceous plugs (whiteheads and blackheads), thereby reducing non-inflammatory lesion counts. We believe this caused a placebo response rate that was much higher than the placebo response rates seen in other topical Phase 2 acne trials. As a result of the inadequate placebo, we developed a new proprietary placebo formulation for our Phase 2b clinical trial.
Once weekly vs. Biweekly Treatment Schedule: Due to this being the first time XYNGARITM was studied in moderate-to-severe acne patients for 12 weeks, a conservative study design was chosen to ensure patient tolerability and safety while attempting to maintain efficacy. Therefore, we allowed IGA treatment responders (IGA score of 0 or 1) to move to a biweekly or every other week application schedule as discussed above. This resulted in 3 out of 27 patients in the XYNGARITM + 3% H2O2 group and 0 out of 29 patients in the placebo + water group moving from an IGA score of 1 (treatment responder) at week 8 and regressing to an IGA score of 2 (treatment failure) at week 12. Therefore, our Phase 2b clinical trial of XYNGARITM in moderate-to-severe acne patients incorporated only once weekly applications for 12 weeks with no biweekly option.
No statistical or clinical difference was seen between the placebo + 3% H2O2 and the placebo + water groups, which we believe indicates that 3% H2O2 by itself does not have a treatment effect.

XYNGARITM next steps for acne
After receiving positive feedback and alignment with FDA from our End of Phase 2 meeting in June of 2023 we began enrolling patients in our XYNGARITM Phase 3 STAR-1 clinical trial in moderate-to-severe acne in December 2023.
The XYNGARITM Phase 3 program will include two, multi-center, placebo-controlled trials with identical clinical endpoints as our recent successful Phase 2b clinical trial of XYNGARITM for the treatment of moderate-to-severe acne, followed by a long-term extension study. Once we receive results from the Phase 3 program, assuming positive results, we plan to file an NDA with the FDA shortly thereafter. This Phase 3 program is intended to be designed to demonstrate the safety and efficacy of the treatment of XYNGARITM relative to placebo for the treatment of moderate-to-severe acne. Prior to, or in parallel with our planned Phase 3 program, we intend to continue conducting and complete the additional non-clinical studies necessary to support the filing of an NDA. If XYNGARITM is approved for the treatment of acne, we believe XYNGARITM can eventually be an attractive prescription to over-the-counter switch, or Rx-to-OTC, target, which could provide a substantially larger sales opportunity. There can be no assurance that XYNGARITM will receive FDA approval for the treatment of acne.
XYNGARITM Phase 1a Clinical Results for Psoriasis
We completed a Phase 1a POC trial of XYNGARITM for the treatment of mild-to-moderate psoriasis. This was an open-label, multi-center, 12-week study in 30 mild-to-moderate psoriasis patients with psoriatic lesions covering between 2-30% of body surface area. The trial aimed at evaluating the tolerability, safety, and efficacy of once weekly treatments of XYNGARITM, which consists of 2 grams of Spongilla powder mixed with 6 mL of 3% H2O2. One mild or moderate lesion was selected, and patients were required to apply XYNGARITM to the entire lesion, once weekly for 12 weeks with the first two weeks of treatment applied in office under the supervision of trained staff, then the remaining 10 weekly treatments were applied at home by the patient.
The endpoints in this study included:
All efficacy analyses were performed using the As-Treated population, which consists of all enrolled patients who received at least one dose of study medication and the per protocol population, which consists of all enrolled patients with no significant protocol violations during the study that would affect the efficacy analyses.
Table of Contents
The trial was completed in August 2021 and showed an acceptable safety and tolerability profile that we believe is clinically meaningful and warrants further investigation of XYNGARITM as a potential treatment for mild-to-moderate psoriasis. XYNGARITM was able to achieve a PGA score of 0 or 1 for the target lesion in 29.6% of patients at week 8. XYNGARITM also demonstrated a total PASI score of 0 or 1 for the target lesion in 25.9% of patients at week 8. Notably, XYNGARITM demonstrated a 19.6% reduction from baseline in pruritus (itch) at week 8 with a peek reduction of 22.5%. We believe these findings from a POC trial are encouraging for the potential use of XYNGARITM as an easy to apply topical treatment for mild-to-moderate psoriasis with an acceptable safety and tolerability profile.
No reported drug-related severe adverse events were reported in the trial and only two treatment emergent adverse events were reported, both being application site pruritus. Additionally, the drug also appeared to be tolerated by a majority of patients. Of those patients who did report tolerability issues, they also reported that the issues were usually transient and resolved quickly without intervention.
XYNGARITM next steps for psoriasis
We are pleased with data already seen in our Phase 1 POC trial, especially seeing a reduction in itch as that is one of the main complaints of patients suffering from psoriasis. We are in the process of designing a Phase 2 study of XYNGARITM for the treatment of psoriasis. The Phase 2 study will be a larger randomized, double-blind, placebo control study of XYNGARITM for the treatment of psoriasis. Based on the data from the Phase 1b proof of concept study we are considering adding additional arms to examine once versus twice weekly treatment, potentially enhancing the treatment effect seen in our Phase 1b trial. Additionally, due to the unique nature of psoriasis and the general thickness of psoriatic plaques, we may also examine increasing the application pressure and the length of application. We believe that the thicker psoriatic plaques may require a more intensive treatment compared to the application regimen for acne where there is no thickened skin. We believe XYNGARITM could be a first in class treatment option for psoriasis patients. The XYNGARITM program for psoriasis is currently on hold with further advancement subject to obtaining additional financing and/or a strategic partner. There can be no assurance that XYNGARITM will receive FDA approval for the treatment of psoriasis.
DMT410 Phase 1b-Primary Axillary Hyperhidrosis
In the first quarter of 2019, we completed a Phase 1b, open-label, POC trial of DMT410 for the treatment of moderate-to-severe primary axillary hyperhidrosis. In this study we treated ten (10) patients with one application of our proprietary sponge powder followed by one topical application of BOTOX, reconstituted per label, to each axilla. Patients were followed for 4 weeks after which time their sweat production was measured and compared with baseline measurements.
The endpoints for this trial included:
· percentage change in gravimetric sweat production.
Table of Contents
After 4 weeks, 80% of patients saw a decrease in gravimetric sweat production greater than 50%, 85% of patients had gravimetric sweat production of less than 50mg, and patients had a 75% decrease in gravimetric sweat product from baseline. Based on this clinical data, we believe that we were able to deliver botulinum toxin into the dermis through topical application for the treatment of primary axillary hyperhidrosis. Treatment with DMT410 also had an acceptable safety and tolerability profile.
On January 17, 2025, we entered into the Clinical Trial Agreement with Revance Therapeutics, Inc. (Revance), who recently merged with Crown Laboratories, pursuant to which we in collaboration with Revance intend to conduct a multi-center clinical trial to evaluate the topical application of XYNGARITM, with DAXXIFY®. Under the Clinical Trial Agreement, we intend to sponsor, conduct, and fund a Phase 2a clinical trial to evaluate the safety, tolerability and preliminary efficacy of XYNGARITM and DAXXIFY® versus XYNGARITM and placebo in patients with moderate-to-severe axillary hyperhidrosis for 16 weeks. The Revance Trial is anticipated to be randomized (1:1:1:1), double-blind, placebo-controlled, and intends to enroll approximately 48 patients across sites in the United States. The endpoints are anticipated to be (i) the percent of patients with greater than 50% reduction in gravimetrically measured sweat production from baseline, (ii) the percent of patients with gravimetric sweat production less than 50mg, and (iii) the mean absolute change from baseline in gravimetrically measured sweat production. Patients are anticipated to be evaluated at four regular intervals. Under the Clinical Trial Agreement, we and Revance will form a joint development committee to facilitate communications between the parties related to the Revance Trial. If successful, we plan to explore a broader partnership with Revance to study DMT410 in additional indications. There can be no assurances that DMT410 will receive FDA approval for the treatment of hyperhidrosis.
DMT410 Phase 1b— Aesthetic Conditions
In November 2020, we enrolled our first patient in a Phase 1b open-label, POC trial of DMT410 for the treatment of upper facial lines along with multiple other aesthetic skin conditions that are affected by delivery of toxin to the dermis such as pore size, sebum production, brightness, luminosity, fine lines, and Global Aesthetic Improvement. Due to the fact that we do not own rights to a botulinum toxin product, we were required by the FDA to conduct this trial using an approved indication for BOTOX, upper facial lines, an approved dose for this indication (64 units of botulinum toxin) and an approved route of administration, which is typically injections into the muscle rather than the dermis. However, our primary interest was studying the clinical effect of DMT410 for the aesthetic skin conditions that require delivery of botulinum toxin to the dermis rather than the muscle. This is due to our belief that DMT410 only delivers botulinum toxin to the dermis and not the muscle, thus limiting the botulinum toxin’s effect to aesthetic conditions which arise in the dermis like fine lines, pore size, sebum production, and others. With these constraints, we initiated the POC trial by enrolling ten (10) female patients, age 18 or older, each receiving one treatment of DMT410, consisting of one topical application of our proprietary sponge powder followed by one topical application for BOTOX, reconstituted per label, to the upper face. Patients were followed for sixteen (16) weeks to determine the achievement of our endpoints along with the duration of effect. We also collected safety and tolerability data. We received top-line data from this study in the November 2021, and believe that we achieved results in multiple aesthetic endpoints sufficient to warrant further investigation of DM410 for the treatment of various aesthetic skin conditions.
The endpoints for this trial were:
The efficacy analysis was conducted on the ITT and Per Protocol (PP), meaning all patients completing the study without a major protocol violation, populations. In addition to the physician measured endpoints listed above, we also implemented 2-dimensional VISIA and 3-dimensional PRIMOS imaging technology from Canfield Scientific to provide objective analysis of many of the aesthetic endpoints.
Based on the assessment of forehead, lateral canthal, and glabellar lines, no patient was considered a responder in this study, while some patients did achieve at least a one-grade change throughout the course of the study. This result was not unexpected as BOTOX is only approved for injections into the muscle for these indications and we did not believe that we would see any potential distant spread of toxin outside of the dermis to the muscle. Seeing no potential distant spread of toxin was encouraging for us as it provides important safety data that while DMT410 can be applied over a larger treatment area than injections, it does not appear to travel beyond the dermis which may cause unwanted facial effects.
We believe the real potential of DMT410 lies in the aesthetic endpoints that can be affected by delivering BOTOX to the dermis rather than the muscles. These clinical endpoints include pore size, global aesthetic improvement, brightness, luminosity, and fine lines. The following table (Image 11) shows the improvements in pore size, or a decrease in overall pore size, with patients achieving at least a 25% improvement in pore size, for assessment of GAI, or the overall improvement in skin quality, the with patients achieving at least a 25% improvement in GAI, for assessment of brightness, or the skin’s combined uniformity of color and texture, with patients having at least a 1-point improvement in brightness, and for assessment of luminosity, or the intensity of light area reflected off the face, with patients having at least a 1-point improvement in brightness.

Image 11: Aesthetic Endpoints
In addition to the physician measured endpoints, we also utilized Canfield Scientific’s 2-dimensional VISIA and 3-dimensional PRIMOS imaging technologies to gather additional objective data on some of the key endpoints. Based on the VISIA system patients saw a 14.1% reduction in pore count and a 14.3% reduction in pore area at week 4. Patients also saw a 16.5% reduction in wrinkle count and a 11.5% reduction in wrinkle area at week 4. Using the PRIMOS image analysis patients saw a percent decrease in mean line, which consist of the deeper facial lines, of 12.1% and a percent change in mean roughness, which consists of the superficial fine lines, of 6.5%. We believe the subjective effects seen by the treating physicians were further validated by the objective measures using Canfield camera systems.
No reported drug-related adverse events were reported in the trial. The drug appeared to be well tolerated by patients, with only mild stinging and erythema reported 15 minutes after treatment and no tolerability issues reported at week 4, 8, 12 or 16.
DMT410 next steps for aesthetics
We are very encouraged by the results from our Phase 1b POC trial of DMT410 for the treatment of multiple aesthetic skin conditions. This was designed to be a signal detection trial of DMT410 for the treatment of a variety of aesthetic skin conditions based on the clinical trial design constraints, including the limitation on the quantity of BOTOX that we were able to apply, the clinical endpoints that needed to be included, and the area of the face that could be treated. Even with these limitations we believe that we achieved results sufficient to warrant the continued development of this program as there remains no approved botulinum toxin, whether via injection or topical, to treat many of the endpoints in which we saw a treatment effect. We believe this is further supported by the fact that many of the endpoints saw an improvement by week eight (8) or twelve (12) and started to return towards baseline at week 16. This is consistent with the knowledge that BOTOX lasts for about three (3) months before the effect begins to fade. We believe that if we can conduct a larger Phase 2 clinical trial that consists of multiple doses of botulinum toxin, we will be able to find the optimal dose for the treatment of a variety of aesthetic skin conditions including pore size, sebum production, fine lines, luminosity, brightness, and overall aesthetic improvement. We know that botulinum toxin has shown efficacy of these endpoints but there has been very little research conducted on the optimal dose or administration procedure, likely due to challenges with intradermal injections and the lack of topical applications that can effectively deliver botulinum toxin to a large enough treatment area as required to treat many of these aesthetic skin conditions. We believe DMT410 can meet this need as shown by our Phase 1b data, so we continue to discuss partnership opportunities with Revance and other botulinum toxin companies that may be interested in helping us further develop our DMT410 program for multiple aesthetic skin conditions. There can be no assurances that we are able to successfully negotiate a partnership with a botulinum toxin company for aesthetic skin conditions or that DMT410 will receive FDA approval for the treatment of any aesthetic skin conditions.

Manufacturing
We do not currently own or operate any manufacturing facilities and do not plan to own any in the near future. We have been relying on our third-party partners for the manufacture of our products used in pre-clinical studies and clinical trials and will likely continue to rely on these partners in the near term for the commercial manufacturing of our drug substance and drug product, if our drug product candidates are approved. Manufacturing of the active pharmaceutical ingredient, or API, for our product candidates requires a raw material that is derived from a natural source.
To date, we have obtained naturally sourced Spongilla raw material directly from our supplier based in Russia. In February 2020, we signed an exclusive supply agreement with this supplier of Spongilla raw material. Our supplier has over 22 years of experience collecting and processing Spongilla and has the capacity to collect and process large quantities of Spongilla per year. We believe our supplier is able to and will continue to be able to harvest sufficient quantities of raw material to fulfill our development and potential commercial needs, if a product candidate is approved using this raw material. We received multiple shipments of Spongilla raw material from our supplier during fiscal years 2023 and 2024 containing additional quantities of Spongilla raw material, which we believe will provide us with sufficient quantities of Spongilla to initiate and complete the Phase 3 program in moderate-to-severe acne, complete a Phase 2b trial of DMT410 in axillary hyperhidrosis and support the filing of an NDA for XYNGARITM in acne in the event of successful completion of the two Phase 3 studies. However, we are exploring alternative manufacturing sources in order to ensure that we have access to sufficient manufacturing capacity to meet potential demand for any of our product candidates in a cost-efficient manner. See “Business—Material Agreements— Supply Agreement between Dermata Therapeutics LLC and Reka-Farm LLC” for more information regarding our supply of Spongilla.
Development and commercial quantities of any drug product candidates that we may develop will need to be harvested, manufactured in facilities, and processed in compliance with the requirements of the FDA and the regulatory agencies of other jurisdictions in which we are seeking approval. We currently employ internal resources to manage our manufacturing contractors. The relevant manufacturers of our drug product candidates have advised us that they are in compliance with both current Good Laboratory Practices, or cGLP, and cGMP.
We have relied upon our complete supply chain while supporting our Phase 2 and Phase 3 clinical supply requirements and we are confident that our manufacturers have the ability to scale our processes to support our future commercial requirements. Our suppliers and manufacturers were specifically selected based on the capabilities of their organization, their compliance to regulations, their personnel and the type and capabilities of their equipment. Testing methods for each stage of the manufacturing process form acquisition of raw materials through production of finished drug product have been developed and satisfactorily qualified per the FDA’s phase appropriate regulations relating to clinical materials for human use. Analytical methods and operational procedures related to each stage of our production operations including product release will continue to evolve and be validated as part of our overall development plan for Phase 3 clinical supplies and commercial production.
Commercialization
Given our stage of development, we do not currently have any internal sales, marketing, or distribution infrastructure or capabilities. If approved, we intend to commercialize XYNGARITM, or any other product candidates that we may successfully develop, in the United States by building a specialized sales organization focused on dermatologists or partnering with a company that has an already established sales force focused on dermatologists. We believe a scientifically oriented, customer-focused team of approximately 50-60 sales representatives would allow us to reach our targeted dermatologists in the U.S. with the highest potential for prescribing XYNGARITM. In the future, we may develop and commercialize XYNGARITM for additional geographic regions, independently or with a strategic partner. If XYNGARITM is approved, and we are able to successfully commercialize it, we believe XYNGARITM can eventually become an attractive Rx-to-OTC switch target, which could provide a substantially larger addressable market and an expanded sales opportunity.

Competition
The medical and aesthetic pharmaceutical industries in which we plan to operate are competitive and subject to changes in practice. While we believe that our unique natural technology, knowledge, experience and resources provide us with competitive advantages, we may face competition from many different sources with respect to our current programs or any other product candidates that we may seek to develop or commercialize in the future. Possible competitors may include pharmaceutical companies, academic and medical institutions, governmental agencies and public and private research institutions. These prospective competitors have the ability to effectively commercialize, market and promote approved products, including communicating the effectiveness, safety and value of products to actual and prospective customers.
Many of our prospective competitors have substantially greater manufacturing, financial, research and development, personnel, and marketing resources than we do. Our prospective competitors may also have more experience and expertise in obtaining marketing approvals from the FDA and foreign regulatory authorities. In addition to product development, testing, approval and promotion, other competitive factors in the pharmaceutical industry include industry consolidation, product quality and price, product technology, reputation, customer service and access to technical information. As a result, our prospective competitors may be able to develop competing or superior products and compete more aggressively and sustain their competitive advantage over a longer period of time than us. Our products may be rendered obsolete or may lack economic viability in the face of competition.
The key competitive factors affecting the success of XYNGARITM , if approved, will likely be its efficacy, safety, convenience of administration and delivery, price, and the availability of reimbursement from government and other third-party payors. With respect to XYNGARITM for the treatment of moderate-to-severe acne, if approved, we will primarily be competing with therapies such as other topical products, oral products, in-office procedures, such as laser surgery, off-label drugs, over the counter medication and homeopathic remedies. With regards to XYNGARITM for the treatment of mild-to-moderate psoriasis, if approved, we will face competition from topical therapies, oral therapies, systemic therapies, photo therapies and homeopathic treatments. However, based on our clinical trials, we believe that XYNGARITM has multiple competitive advantages over current treatment alternatives with significantly less adverse side effects. Our main competition in these indications will be with products from Sun Pharmaceuticals Industries Ltd., Sol-Gel Technologies Ltd., Arcutis Biotherapeutics, Inc., Almirall S.A., Galderma S.A., Pfizer Inc. See “Business – Clinical Progress of our Lead Product Candidates” for the results of our completed and ongoing clinical trials. While we are unaware of any potential similar competitive topical products to XYNGARITM for the treatment of acne and psoriasis, it is possible that such potentially similar competitive products are currently being developed.
We are also in early stages of clinical development for DMT410 for treating various medical and aesthetic skin conditions and diseases, and if we obtain marketing approval in the future, we will compete with traditional therapies, such as topical products, oral products, in-office procedures, such as botulinum toxin injections, off-label drugs, over the counter medication and homeopathic remedies, as well as additional new entrants to the applicable markets.
We also expect to face competition in our efforts to identify appropriate collaborators or partners to help commercialize our product candidate portfolio in our target commercial markets.
Intellectual Property
Overview
Our commercial success depends in part on our ability to obtain and maintain proprietary protection for XYNGARITM, DMT400, DMT410 and any of our future product candidates, medical devices, methodologies, assays, drug development technologies, harvesting procedures, know-how; to operate without infringing on or otherwise violating the proprietary rights of others; and to prevent others from infringing or otherwise violating our proprietary rights. Our strategy is to protect our proprietary position by, among other things, filing U.S. and foreign patent applications related to our product candidate and other proprietary technologies, inventions and improvements that are important to the development and implementation of our business. We also rely on trade secrets, trademarks, know-how, continuing technological innovations, exclusivity agreements, nondisclosure and confidentiality agreements, license agreements, assignment of inventions and potential in-licensing opportunities to develop and maintain our proprietary position.
Table of Contents
Patent Portfolio
Our patent estate consists of in-licensed and solely owned patent applications. Typically, we initially file U.S. provisional patent applications and then file applications directly or under the Patent Cooperation Treaty, or PCT, which is an international patent law treaty that provides a unified procedure for filing a single initial patent application to seek patent protection for an invention simultaneously in any one of the designated member jurisdictions and states, including in the U.S. Although a PCT application does not issue as a patent, it allows the applicant to seek protection in any of the member states through national phase applications filed at a later date. We currently have multiple patents and patent applications in our patent portfolio and continue to pursue and seek additional patent coverage of all our product candidates.
XYNGARITM
Our XYNGARITM portfolio includes two families, one in-licensed and one owned by Dermata. The in-licensed family includes patents and patent applications in-licensed from Villani, Inc. related to therapeutic compositions and methods for treating skin conditions. The in-licensed portfolio consists of one pending non-provisional U.S. patent application, two granted U.S. patents, and granted foreign patents in Australia, Brazil, Canada, France, Germany, Ireland, Italy, Mexico, Russia, Singapore, South Korea, Spain, Switzerland, and the United Kingdom. Additionally, the issued foreign patent in Japan, has lapsed and is no longer in force or valid. These in-licensed patents expired between 2022 and 2023 and did not receive any patent term adjustments or extensions. Based on the anticipated timing of any potential FDA approval of XYNGARITM for acne, the patents that expired in 2022 and 2023 are not material to our business, as we do not expect these patents to provide any protection for our product candidates and thus we have provided our licensor with a notice of abandonment for certain licensed patents. We expect our intellectual property portfolio to be protected by any potential NCE exclusivity for XYNGARITM and our other product candidates, the maintaining of our exclusive supply agreement for our raw material requirements, and our continued efforts to protect our proprietary information. We also have an additional Dermata owned family related to XYNGARITM, with a recent patent issuance in the U.S. by the United States Patent and Trademark Office, entitled “Compositions and methods for the treatment of skin conditions” (U.S. Patent No. 12,208,123). We also have applications pending in Australia, and Canada. This family refers to specific attributes of the XYNGARITM API and drug product as well as treatment related attributes for the treatment of acne based on the data received prior to its filing. Patents in this patent family, if granted, are expected to expire in 2041, absent any patent term adjustments or extensions.
DMT410
Our DMT410 portfolio includes two families owned by Dermata. The first family consists of one issued patent in Japan, one allowed application in Australia, a pending non-provisional U.S. patent application, and six pending foreign patent applications in Canada, China, the European Patent Office, Japan, Hong Kong, and South Korea. These patents/patent applications relate to compositions for the treatment of skin diseases using our proprietary sponge powder in combination with multiple types of botulinum toxin for both medical and aesthetic skin conditions and diseases. Patents in this patent family, if granted, are expected to expire in 2039, absent any patent term adjustments or extensions. The second family is related to certain of our clinical methods related to sponge powder and botulinum toxin. This second family consists of two pending US non-provisional applications and additional applications pending in Australia, Canada, the European Patent Office, Japan, and South Korea. Patents in this patent family, if granted are expected to expire in 2041, absent any patent term adjustments or extensions.
DMT400
Our DMT400 portfolio includes three families owned by Dermata. The first family consists of pending applications in the U.S., Canada, and Japan covering our sponge powder in combination with many approved and development stage monoclonal antibodies for the treatment of skin diseases. Patents in this patent family, if granted, are expected to expire in 2039, absent any patent term adjustments or extensions. The second family consists of pending applications in the U.S., Australia, Japan, and South Korea, covering compositions for the treatment of conditions by dermal fillers in combination with our proprietary sponge powder. Patents in this patent family, if granted, are expected to expire in 2040, absent any patent term adjustments or extensions. The third family consists of a pending PCT application filed in January of 2024, covering the compositions for the treatment of conditions by vaccines in combination with our proprietary sponge powder.
Although we believe our patent portfolio offers significant protection for XYNGARITM, DMT410 and DMT400 and additional combination regimens, the protection offered by our patents may be, to some extent, more limited than the protection provided by patents which claim chemical structures which were previously unknown. Accordingly, other parties may compete with us, for example, by independently developing or obtaining competing topical formulations that design around our patent claims, but which may contain the same or similar active ingredients, or by seeking to invalidate our patents.
The term of individual patents depends upon the laws of the countries in which they are obtained. In most countries in which we file, the patent term is 20 years from the earliest priority date of filing of a non-provisional patent application. However, the term of United States patents may be extended for delays incurred due to compliance with the FDA, requirements or by delays encountered during prosecution that are caused by the United States Patent and Trademark Office, or the USPTO. For example, the Hatch-Waxman Act permits a patent term extension for FDA-approved drugs of up to five years beyond the expiration of the patent. The length of the patent term extension is related to the length of time the drug is under regulatory review. Patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, and only one patent applicable to an approved drug may be extended. Similar provisions are available in Europe and other jurisdictions to extend the term of a patent that covers an approved drug. In the future, if and when our product candidates receive FDA approval, we expect to apply for patent term extensions on patents covering those product candidates. We intend to seek patent term extensions in any jurisdiction where these are available and where we also have a patent that may be eligible; however there is no guarantee that the applicable authorities, including the United State Patent and Trademark Office and United States FDA, will agree with our assessment of whether such extensions should be granted, and even if granted, the length of such extensions.

Other Intellectual Property
In addition to patent protection, we also rely heavily on trade secrets, including unpatented know-how, technology innovation, technical specifications and assays and other proprietary information in attempting to develop and maintain our competitive advantage. We believe our ability to protect our unpatented know-how and trade secrets are as important if not more important than our patent portfolio due to the complex nature and lack of expiration associated with such information.
We seek trademark protection in the United States and in certain other jurisdictions where available and when we deem appropriate. We currently have registrations for Dermata in the United States and multiple other jurisdictions. We intend to file applications for trademark registrations in connection with our therapeutic candidates in various jurisdictions, including the United States.
Material Agreements
License Agreement between Dermata Therapeutics, LLC and Villani, Inc.
On March 31, 2017, we entered into a License Agreement (or, the License Agreement) with Villani, Inc. (or, Villani), whereby Villani has granted us an exclusive, sub-licensable, royalty-bearing license (or, the License) under the Licensed Patents (as defined in the License Agreement), to formulate, develop, seek regulatory approval for, make or sell products that contain Spongilla lacustris (alone or in combination with other active or inactive ingredients) for the treatment of diseases, disorders and conditions of the skin, including but not limited to acne, rosacea, psoriasis, atopic dermatitis, seborrheic dermatitis, actinic keratosis and eczema that were developed using certain licensed know-how (or, the Licensed Products). We are responsible for the development (including manufacturing, packaging, non-clinical studies, clinical trials and obtaining regulatory approval) and commercialization (including marketing, promotion, distribution, etc.) for all Licensed Products.
In partial consideration of the License, we forgave our outstanding loan to Villani in the amount of $400,000 and agreed to make future milestone payments to Villani. The milestone payments due to Villani under the License Agreement have been amended to the amounts described below in connection with our entry into the Second License Amendment (as defined below).
The License Agreement may be terminated (i) by either party for material breach with 90 days written notice, or 30 days’ notice if for material payment breach, if such material breach is not cured within such notice period, (ii) immediately upon written notice to either party if either party initiates a voluntary bankruptcy proceeding, dissolves or winds-up its business, (iii) immediately upon written notice to either party if either party becomes subject to involuntary bankruptcy proceedings, if such proceedings are not dismissed or stayed within 90 days.
The License Agreement includes customary terms relating to, among others, indemnification, intellectual property protection, confidentiality, remedies, and warranties.
On June 4, 2019, we entered into a License Amendment and Settlement Agreement (or the First License Amendment) with Villani. Pursuant to the First License Amendment, we made milestone payments to Villani in an aggregate amount of $750,000, and in exchange for certain know-how, we issued to Villani 5,221,156 units of our Series 1c Preferred Units (which units were converted into shares of our Series 1c Preferred Stock in connection with our conversion into a Delaware corporation, which was equal to 5% of our total capitalization (on a fully-diluted basis) at the time of issuance). At the time of issuance, these units were valued at $730,962. We subsequently cancelled the shares of Series 1c Preferred Stock issued to Villani pursuant to the Second License Amendment, as described below. Pursuant to the First License Amendment, we also agreed to make certain milestone payments to Villani, which rates were subsequently amended pursuant to the Second License Amendment, as discussed below.
On July 30, 2021, we entered into a Second Amendment to the License and Settlement Agreement (or, the Second License Amendment), whereby, for the settlement of certain disputes arising under the First License Amendment, we agreed to exchange the shares of Series 1c Preferred Stock owned by Villani for an increase of milestone payments and royalty rates due to Villani under the License Agreement. The resulting royalty rates payable pursuant to the Second License Amendment are equal to single-digit percentages of net sales of Licensed Products and HMW Combination Products (as defined in the License Agreement), subject to certain adjustments as set forth in the Second License Amendment. Royalties are payable on a country-by-country and Licensed Product-by-Licensed Product basis, for the period of time from the effective date of the License Agreement until the later of (i) the expiration of the last to expire valid claim in such country (which expired in 2023), (ii) the expiration of regulatory exclusivity for such Licensed Product in such country, and (iii) 15 years from the date of the first commercial sale of the Licensed Product in such country. Pursuant to the Second License Amendment, if we sublicense the License, we are obligated to pay to Villani a sublicense fee of between 10% and 30% of Sublicense Revenues (as defined in the License Agreement). Such future milestone payments due to Villani (all payable to Villani in cash or in equity, at the option of Villani) are in aggregate amounts of up to $3.5 million in development milestones and $37.0 million in sales milestones. To date, we have paid Villani a total of $1,750,000 in connection with the License Agreement, inclusive of a $750,000 milestone payment and $1.0 million payment upon the closing of our initial public offering.

Clinical Trial Collaboration Agreement between the Company and Revance Therapeutics, Inc.
On January 17, 2025, the Company entered into a Clinical Trial Collaboration Agreement (Clinical Trial Agreement) with Revance Therapeutics, Inc. (Revance), pursuant to which the Company and Revance intend to conduct a multi-center clinical trial (Trial) to evaluate the topical application of XYNGARITM, the Company’s topical Spongilla powder (formerly referred to as DMT310), with DAXXIFY® (daxibotulinumtoxinA-lanm), Revance’s botulinum toxin type A. Pursuant to the terms of the Clinical Trial Agreement, Revance has granted the Company a non-exclusive, worldwide, non-transferable, royalty-free license, with a right to sublicense (subject to limitations), to use certain Revance intellectual property, solely as necessary or useful for the Company to conduct the trial under the Clinical Trial Agreement. The Company has granted Revance a similar license to use XYNGARITM and other compound(s) under the Clinical Trial Agreement. The Clinical Trial Agreement will terminate upon completion of the Trial, the delivery of the data resulting from the Trial and the completion of any statistical analyses of the data resulting from the Trial. Either party may terminate the Clinical Trial Agreement upon a material breach by the other party that remains uncured following 30 days after the date of written notice of such breach. In addition, either party may terminate the Clinical Trial Agreement immediately upon written notice if such party reasonably deems it necessary in order to protect the safety, health or welfare of subjects enrolled in the Trial. The Company has agreed to sponsor, conduct, and fund the Phase 2a clinical trial, but no financial obligations or consideration is contemplated in the Clinical Trial Agreement.
Supply Agreement between the Company and Reka-Farm LLC
On February 27, 2020, we entered into an exclusive Supply Agreement (or, the Supply Agreement) with Reka-Farm, LLC (or, Reka-Farm), whereby Reka-Farm will supply us with the Spongilla raw materials necessary for use in the development of our product candidates. The Supply Agreement has an indefinite term unless and until terminated. For the term of the Supply Agreement, Reka-Farm is prohibited from supplying Spongilla for development and sale of any other product outside of the Russian Federation, other than Cosmetic Products (as defined in the Supply Agreement).
Pursuant to the Supply Agreement, we shall provide Reka-Farm with two-year rolling forecasts of our Spongilla raw material requirements, and such forecasts shall be provided to Reka-Farm on a semi-annual basis, beginning on January 1, 2021 (each, a Forecast). Pursuant to the Supply Agreement, Reka-Farm has guaranteed its ability to supply us with the required amounts of Spongilla as specified in each Forecast for the first 12 months of each Forecast. All Forecasts are non-binding on us. If Reka-Farm is unable to supply us with Spongilla raw material in accordance with a Forecast, all available quantities of Spongilla then available to Reka-Farm shall be made available to us on a first priority basis until all amounts of Spongilla set forth in the Forecast are supplied.
Pursuant to the Supply Agreement, we pay a pre-negotiated price per kilogram for Spongilla supplied by Reka-Farm, and we are required to pay to Reka-Farm a royalty payment of less than one percent of the Net Sales (as defined in the Supply Agreement) of any products we develop containing Spongilla raw material supplied by Reka-Farm.
The Supply Agreement may be terminated (i) by either party for material breach with 90 days written notice, if such material breach is not cured within such notice period and (ii) by us for any reason or no reason upon 90 days written notice to Reka-Farm.
The Supply Agreement includes customary terms relating to, among others, indemnification, intellectual property protection, confidentiality, remedies, warranties, as well as certain quality requirements.
Government Regulation
Our activities and products are significantly regulated by a number of governmental entities, including the U.S. Food and Drug Administration, or FDA, in the United States and by comparable authorities in other countries. These entities regulate, among other things, the research, development, testing, safety, effectiveness, manufacturing, storage, distribution, labeling, documentation, advertising and sale of our products. We must obtain regulatory approval from the FDA and comparable authorities in other countries, as applicable, for our drug candidates before we can commercialize such drugs in the U.S. and foreign jurisdictions. Product development within this regulatory framework takes a number of years and involves the expenditure of substantial resources. Many drug candidates that initially appear promising ultimately do not reach the market because they are found to be unsafe or ineffective when tested. Our inability to commercialize a product would impair our ability to earn future revenues.
The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable requirements at any time during the product development process, approval process or after approval may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls or withdrawals from the market, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

Development of Drugs in the United States
Pre-Clinical Development
Products that we may develop or acquire in the future must be approved by the FDA before they may be legally marketed in the United States. For new chemical entities, the pre-clinical development stage generally involves synthesizing the active component, developing the formulation and determining the manufacturing process, and drug stability as well as carrying out non-human toxicology, pharmacology and drug metabolism studies that support subsequent clinical testing. These pre-clinical laboratory and animal tests are often performed under the FDA’s Good Laboratory Practices regulations. A drug’s sponsor must submit the result of the pre-clinical tests, together with manufacturing information, analytical data and any available clinical data or literature and a proposed clinical protocol to the FDA as part of an IND application, which is a request for authorization from the FDA to administer an investigational drug or biological product to humans. Similar filings are required in other countries. Laboratory and animal tests continue to be performed after an IND is approved.
Clinical Trials
The clinical stage of development can generally be divided into three sequential phases that may overlap: Phase 1, Phase 2, and Phase 3 clinical trials. In Phase 1, generally, small numbers of healthy volunteers are initially exposed to single escalating doses and then multiple escalating doses of the product candidate. The primary purpose of these studies is to assess the metabolism, pharmacologic action and general safety of the drug. Phase 2 trials typically involve studies in disease-affected patients to determine the dose required to produce the desired benefits, common short-term side effects and risks. Phase 2 studies are typically well-controlled, closely monitored, and conducted in a relatively small number of patients, usually involving no more than several hundred subjects. Phase 3 trials are intended to gather the additional information about effectiveness and safety that is needed to evaluate the overall benefit-risk relationship of the drug and to provide an adequate basis for physician labeling. Phase 3 studies usually include from several hundred to several thousand subjects and are closely controlled and monitored. In addition to these Phase 1-3 trials, other trials may be conducted to gather additional safety, pharmacokinetic and pharmacodynamic information. Pharmaceutical products with active ingredients equal or similar to those already approved by the FDA often have more streamlined development programs than compounds entirely new to the agency, often skipping Phase 1 and 2 trials.
A clinical plan must be submitted to the FDA prior to commencement of a clinical trial. If the FDA has concerns about the clinical plan or the safety of the proposed studies, they may suspend or terminate the study at any time. Studies must be conducted in accordance with good clinical practice and reporting of study progress and any adverse experiences is required. Studies are also subject to review by independent institutional review boards responsible for overseeing studies at particular sites and protecting human research study subjects. An independent institutional review board may also suspend or terminate a study once initiated. Accordingly, we cannot be sure that submission of an IND will result in the FDA allowing clinical trials to begin, or that once begun, issues will not arise that could cause the trial to be suspended or terminated.
Post-approval studies, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. Sometimes, these studies are used to gain additional experience from the treatment of patients in the intended therapeutic condition. In certain instances, the FDA may mandate the performance of Phase 4 studies. In other situations, post-approval studies aim to gain additional indications for a medication or develop new dosage forms for a medication.
Chemistry, Controls and Manufacturing Development
Concurrent with clinical trials, companies typically complete additional animal and laboratory studies, develop additional information about the chemistry and physical characteristics of the drug, determine proposed commercial formulations for the drug, and finalize a process for manufacturing the product in commercial quantities in accordance with FDA’s current Good Manufacturing Practices (“cGMP”) requirements. The manufacturing process must consistently produce quality batches of the drug, and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final drug. In addition, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate the effectiveness of the packaging and that the compound does not undergo unacceptable deterioration over its shelf life.

Disclosure of Clinical Trial Information
Sponsors of clinical trials of FDA-regulated products, including biological products, are required to register and disclose certain clinical trial information on the website www.clinicaltrials.gov. Information related to the product, patient population, phase of investigation, trial sites and investigators, and other aspects of a clinical trial are then made public as part of the registration. Sponsors are also obligated to disclose the results of their clinical trials after completion. Disclosure of the results of clinical trials can be delayed in certain circumstances for up to two years after the date of completion of the trial. Competitors may use this publicly available information to gain knowledge regarding the progress of clinical development programs as well as clinical trial design.
Special Protocol Assessment
The Federal Food, Drug, and Cosmetic Act directs the FDA to meet with sponsors, pursuant to a sponsor’s written request, for the purpose of reaching agreement on the design and size of clinical trials intended to form the primary basis of an efficacy claim in a New Drug Application (NDA) or a Biologic Licensing Application (BLA). If an agreement is reached, the FDA will reduce the agreement to writing and make it part of the administrative record. This agreement is called a special protocol assessment (SPA). While the FDA’s guidance on SPAs states that documented SPAs should be considered binding on the review division, the FDA has latitude to change its assessment if certain exceptions apply. Exceptions include public health concerns emerging that were unrecognized at the time of the protocol assessment, identification of a substantial scientific issue essential to the safety or efficacy testing that later comes to light, a sponsor’s failure to follow the protocol agreed upon, or the FDA’s reliance on data, assumptions or information that are determined to be wrong.
Review and Approval in the United States
Following pivotal or Phase 3 trial completion, data are analyzed to determine safety and efficacy. Data are then filed with the FDA in an NDA or BLA, along with proposed labeling for the product and information about the manufacturing and testing processes and facilities that will be used to ensure product quality. In the United States, FDA approval of an NDA or BLA must be obtained before marketing a pharmaceutical product. The NDA or BLA must contain proof of safety, purity, potency, and efficacy, which entails extensive pre-clinical and clinical testing.
The FDA will likely re-analyze the clinical trial data, which could result in extensive discussions between the FDA and us during the review process. The review and evaluation of applications by the FDA is extensive and time consuming and may take several years to complete. The FDA may conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether they comply with current good manufacturing practice requirements and may also audit data from clinical and pre-clinical trials.
There is no assurance that the FDA will act favorably or quickly in making such reviews and significant difficulties or costs may be encountered in our efforts to obtain FDA approvals. The FDA may require that certain contraindications, warnings or precautions be included in the product labeling, or may condition the approval of the NDA or BLA on other changes to the proposed labeling, development of adequate controls and specifications, or a commitment to conduct post-marketing testing or clinical trials and surveillance programs to monitor the safety of approved products that have been commercialized. Further, the FDA may place conditions on approvals including the requirement for a risk evaluation and mitigation strategy, or REMS, to assure the safe use of the drug. If the FDA concludes a REMS is needed, the sponsor of the NDA or BLA must submit a proposed REMS; the FDA will not approve the NDA or BLA without an approved REMS, if required. A REMS could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of products. Product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur.
Orphan Drug Designation
Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States. Orphan product designation must be requested before submitting an NDA or BLA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan product designation does not convey any advantage in or shorten the duration of regulatory review and approval process. In addition to the potential period of exclusivity, orphan designation makes a company eligible for grant funding of up to $400,000 per year for four years to defray costs of clinical trial expenses, tax credits for clinical research expenses and potential exemption from the FDA application user fee.
