PART I

ITEM 1. BUSINESS

Overview

We are a therapeutics company developing and commercializing medications for the treatment of dermatologic diseases, including skin cancers. Currently, our commercial product and portfolio of product candidates are clinician administered therapies in areas of high unmet need. This product portfolio consists of one product with an approved indication for molluscum contagiosum, or molluscum, with the potential for several follow-on indications, as well as additional pipeline product candidates. Our commercial product, YCANTH (VP-102), was approved by the U.S. Food and Drug Administration, or FDA, in July 2023 for the treatment of molluscum in adult and pediatric patients two years of age and older. YCANTH (VP-102) is a proprietary drug-device combination that contains a GMP-controlled formulation of cantharidin. We are currently developing YCANTH (VP-102) for a potential follow-on indication for the treatment of common warts. Our second development candidate, VP-315 (ruxotemitide), is an oncolytic peptide-based injectable therapy for the potential treatment of dermatology oncologic conditions, including basal cell carcinoma, or BCC.

We are currently focusing our efforts and financial resources on (i) the commercialization of YCANTH (VP-102) for the treatment of molluscum, (ii) the development of YCANTH (VP-102) for the treatment of common warts and (iii) the development of VP-315 for the treatment of BCC.

YCANTH (VP-102)

Commercial - Treatment of Molluscum

On July 21, 2023, YCANTH (VP-102) (cantharidin) 0.7% topical solution was the first product approved by the FDA for the treatment of molluscum in adult and pediatric patients two years of age and older. We commercially launched YCANTH (VP-102) in August 2023 in the United States for the treatment of molluscum. We have built a specialized sales organization consisting of approximately 40 field employee sales representatives as of December 31, 2025, in the United States focused on pediatric dermatologists, dermatologists, pediatricians and select other primary care health care providers, or HCPs.

Molluscum is a highly contagious common skin disease caused by a pox virus that produces multiple raised flesh-colored papules, or skin lesions. Molluscum typically presents with 10 to 30 lesions and can present with over 100 lesions. If left untreated, molluscum lesions persist for an average of 13 months, with cases remaining unresolved for up to five years. The symptoms of molluscum tend to cause considerable anxiety, and parents frequently seek treatment due to its highly contagious nature and physical appearance.

We estimate approximately 6 million people in the United States have molluscum of which we estimate that approximately 1 million are diagnosed annually. Molluscum has a 5% to 11% prevalence rate in children with the greatest incidence in individuals aged one to 14 years old. Accordingly, we estimate this represents a total addressable U.S. market of over $1 billion. We believe that the molluscum prevalence rate in the European Union and Asia is comparable to the United States.

In March 2024, YCANTH’s (VP-102) active pharmaceutical ingredient, or API, received New Chemical Entity (NCE) status and a listing in the Orange Book from the FDA, providing a minimum five years of regulatory exclusivity. We are continuing to explore the potential for YCANTH (VP-102) to obtain pediatric exclusivity in common warts. The Orange Book is an FDA publication that provides a list of drugs approved as safe and effective and also serves as the regulatory resource for information on drug marketing availability, bioequivalence, drug substitution, and patent and exclusivity data. The Orange Book also lists patents covering those drugs, approved methods of their use and regulatory exclusivity to which they may be entitled.

Physicians obtain YCANTH (VP-102) in two primary ways: 1) through a "white bag" service from a retail independent or specialty pharmacy or 2) on a buy and bill basis through our distribution partners. Effective April 1, 2024, YCANTH (VP-102) is reimbursed under a permanent J-code (J7354). J-codes are a type of Healthcare Common Procedure Coding System Level II code commonly used to designate non-orally administered drugs and other medical devices. J-codes help determine how managed care organizations reimburse Medical Providers. To date, we have reached approximately 250 million covered lives in the United States through positive insurance payor coverage decisions.

On September 19, 2025, Torii Pharmaceutical Co. Ltd., or Torii, received approval from the Japanese Ministry of Health, Labour and Welfare, or MHLW, for YCANTH (TO-208) for the treatment of molluscum. Torii became a wholly-owned subsidiary of Shionogi & Co., Ltd., on September 1, 2025.

On October 20, 2025, we announced the Committee for Medicinal Products for Human Use of the European Medicines Agency provided positive feedback that supports the filing of a Marketing Authorization Application for YCANTH (VP-102), as a treatment for molluscum in the European Union. We currently retain all global rights to YCANTH (VP-102) outside of Japan and we are currently exploring non-dilutive partnerships to fund development and commercialization for YCANTH (VP-102) for the treatment of molluscum in additional geographic regions outside of the United States and Japan.

On February 9, 2026, Torii announced the launch of YCANTH in Japan as a new treatment option for molluscum in children over 2 years of age.

Pipeline - Treatment of Common Warts

We are also developing YCANTH (VP-102) for the treatment of common warts. Common warts typically result in greater than one lesion. We estimate approximately 22 million people in the United States have common warts, and the total addressable U.S. market to be over $1 billion with an estimated two million patient visits for common warts each year. In the United States, approximately 50% of the patients who seek treatment for common warts are children, and approximately 25% of common warts patients are treated by pediatricians. We believe the common wart patient opportunity in the European Union and Asia is comparable to the United States. There are currently no FDA-approved products indicated for the treatment of common warts. While common warts can be treated with slow acting, over-the-counter products, the warts tend to be highly refractory and a cause for multiple consultations. We believe cantharidin’s role as a widely recognized and effective blistering agent for the treatment of skin lesions, coupled with YCANTH (VP-102)’s safety and efficacy data in clinical trials for the treatment of molluscum and common warts and along with the convenient ease of administration, will allow YCANTH (VP-102) to address many of the shortcomings associated with current over-the-counter therapies.

In June 2019, we announced positive topline results from our COVE-1 Phase 2 open label clinical trial of YCANTH (VP-102) for the treatment of common warts. COVE-1 included two cohorts that evaluated the safety and efficacy of YCANTH (VP-102) in subjects with up to six warts. We held a Type C meeting with FDA on our clinical development plan for YCANTH (VP-102) common warts indication on November 6, 2023. The meeting resulted in gaining alignment on the design of our pivotal Phase 3 clinical development plan to evaluate YCANTH (VP-102) for the treatment of common warts. We have entered into a collaboration and license agreement with Torii Pharmaceutical Co., Ltd., or Torii, pursuant to which Verrica and Torii will equally split the cost of this Phase 3 clinical program, with Torii paying the first $40.0 million of costs when due and us repaying the costs over time, as discussed below. The Phase 3 program, or the Program, commenced in 2025, with the first patient dosed in the United States in December 2025.

VP-315

Pipeline - Treatment of Basal Cell Carcinoma (BCC)

We are also developing VP-315 for the treatment of BCC and potentially additional dermatological oncology indications. We obtained an exclusive worldwide license from Lytix BioPharma AS, or Lytix, to develop and commercialize VP-315 for dermatologic oncology indications, including squamous cell carcinoma, non-metastatic melanoma and non-metastatic Merkel cell carcinoma, and we intend to focus initially on BCC as the lead indication for development. BCC is the most common form of cancer in the U.S., and incidence is rising worldwide. There are approximately 3.6 million diagnoses of BCCs in the U.S. each year, with a high unmet need for new treatment options. More than one out of every three new cancers are skin cancers, and the vast majority are BCCs. In 2021, the estimated global BCC market was $6.7 billion, which is expected to grow to $11.5 billion in 2028. Mohs micrographic surgery is considered the most effective technique for treating BCCs with over 700,000 procedures in the United States annually. We believe VP-315 has the potential to be a non-surgical alternative or neoadjuvant therapy for the treatment of BCC.

The FDA accepted our Investigational New Drug application, or IND, for VP-315 in November 2021. In April 2022, we dosed the first patient in Part 1 of a three-part Phase 2, multicenter, open-label, dose-escalation proof-of-concept trial with a safety run-in designed to assess the safety, pharmacokinetics, and efficacy in subjects with biopsy proven BCC.

In Part 1 of the trial, VP-315 demonstrated a favorable safety and tolerability profile with no reported serious adverse events. We initiated Part 2 of the trial in April 2023. In June 2023, the protocol was amended to remove Part 3 of

5

Table of Contents

the trial and to expand Part 2. The trial enrolled 92 adult subjects with a histological diagnosis of BCC in at least one eligible target lesion.

Part 2 efficacy data showed that approximately 51% of tumors achieved complete histologic clearance. All tumors treated had a reduction in tumor size. Overall tumor size reduction was 86%. Tumor size reduction in subjects who still had any residual tumor was 71%. In November 2024, we also reported additional data based upon a post-hoc analysis of the data from the Study and announced a calculated objective response rate of 97%, with ORR defined as the percentage of study subjects who do not demonstrate disease progression and who experience at least a 30% level of tumor reduction along with partial or complete response following treatment.

In March 2025, we obtained positive feedback from the FDA from the end-of-Phase 2, or EOP2, meeting that supports an efficient Phase 3 program and path to registration for VP-315. This includes two Phase 3 studies, referred to herein as the VP-315 Program, of approximately 100 subjects each in placebo-controlled studies with a primary endpoint of complete clearance at week 14. Additional long-term follow-up studies will all be deferred to post approval commitments. We believe these data, coupled with the EOP2 regulatory feedback, further support the clinical efficacy and histologic clearance observed in the Phase 2 BCC trial. These data support the advancement of the VP-315 Program and we have initiated clinical and chemistry, manufacturing and controls, or CMC, activities to prepare commencement of Phase 3 clinical trials. We may also pursue non-dilutive strategic partnerships to help fund the development and commercialization of VP-315.

In November 2025, we presented additional data at the Society for Immunotherapy of Cancer 40th Annual Meeting, which showed that VP-315 induced a robust local immune response with both cell-mediated and humoral components, effectively shifting the tumor microenvironment from an immunosuppressive to an anti-tumor state, and additional data regarding the histologic assessment in non-injected lesions that suggests a potential abscopal-like effect. Since that presentation, we continued to evaluate the abscopal response in 14 observed but not treated lesions in the Phase 2 study, noting that 3 out of these 14 lesions had complete histologic clearance and that there was a 67% overall reduction in tumor size across all 14 lesions. If this overall product profile could be demonstrated in pivotal Phase 3 testing, we believe VP-315 has the potential to emerge as a non-surgical, immunotherapy treatment option for basal cell carcinoma and other skin cancers.

License Agreements

Torii Pharmaceutical Co., LTD

On March 17, 2021, we entered into a collaboration and license agreement, or the Torii Agreement, with Torii pursuant to which we granted Torii an exclusive license to develop and commercialize our product candidates that contain cantharidin for the treatment of molluscum and common warts in Japan. Additionally, we granted Torii a right of first negotiation with respect to additional indications for the licensed products and certain additional products for use in the licensed field, in each case in Japan. Pursuant to the Torii Agreement, we received payments from Torii of $0.5 million in December 2020 and $11.5 million in April 2021. On July 25, 2022, Torii dosed the first patient in its Phase 3 trial of YCANTH (VP-102) (referred to as TO-208 in Japan) for molluscum in Japan, triggering an $8.0 million milestone payment recognized as license and collaboration revenue for the year ended December 31, 2022.

On May 14, 2024, we entered into the First Amendment to the Torii Agreement, or the First Amendment. Pursuant to the First Amendment, Verrica and Torii will equally split the cost of the global Phase 3 clinical trials of YCANTH (VP-102) for the treatment of common warts, or the Program, with Torii paying all of the costs when due and Verrica will repay half of the costs of the Program to Torii following the conclusion of the trial, or the Company Portion. The Company Portion accrues interest annually at the greater of (i) the one-month SOFR plus 2% and (ii) 6%. Torii has the right to offset the Company Portion plus applicable interest against certain of the milestone-based payments and transfer price payments that would otherwise be due to us under the terms of the Torii Agreement. In addition, if Torii has not received payment or other recoupment in full of the Company Portion plus applicable interest within 60 months after the date on which Torii made its first payment for the Program costs, Torii may invoice us for the remaining Company Portion plus applicable interest. Torii may recoup our share of the costs plus applicable interest against certain development milestone payments and transfer price payments in the Torii Agreement. The first patient in the Program was dosed in December 2025.

In conjunction with the First Amendment, we issued Torii a warrant to purchase up to 50,000 shares of our common stock at an exercise price per share of $95.60. The warrant has a term of ten years from the date of issuance and is exercisable only with respect to the shares that have vested as of the date of exercise. One-third of the shares underlying the

Table of Contents

warrant vested in December 2025 when the first patient was dosed in the Program, and the remaining vesting will occur one-third on the date that the database lock with respect to the Program occurs and one-third on the date we submit an NDA to the FDA for YCANTH (VP-102) for the treatment of common warts.

On June 27, 2025, we entered into the Second Amendment to the Torii Agreement, or the Second Amendment, which further revised the details of the cost sharing arrangement initially negotiated as part of the First Amendment. The Second Amendment among other things provided for the acceleration of an $8.0 million milestone fee payment that was received in July 2025. Pursuant to the Second Amendment, in September 2025, Torii also paid us a $10.0 million milestone payment upon the approval of TO-208, referred to as YCANTH in the U.S., for molluscum in Japan, in cash, rather than as an offset to costs of the Program as originally contemplated under the First Amendment. Torii will be paying the first $40.0 million of out-of-pocket costs when due, with us repaying to Torii half of such costs over time. Consistent with the First Amendment, to repay its portion of the costs of the Program, we will offset amounts otherwise due from Torii for certain transfer price payments, future royalties and remaining development milestones. To the extent the cost of the Program exceeds $40.0 million, we will pay such excess costs, up to a specified maximum amount, and Torii will repay to us half of such costs. The Second Amendment also sets forth that we will initiate a manufacturing transfer to Torii, which is expected to take several years, that will allow Torii to produce YCANTH (TO-208) applicators to be sold in Japan. In the interim, Torii will continue to purchase applicators from us. After the transfer of at least one component of the manufacturing process, we will begin earning royalties related to net sales in Japan of applicators manufactured by Torii and/or its manufacturing partners in lieu of the transfer price for completed applicators.

Lytix BioPharma AS

In August 2020, we entered into an exclusive license agreement with Lytix pursuant to which we obtained an exclusive worldwide license for certain technology of Lytix to develop VP-315 for use in all malignant and pre-malignant dermatological indications, other than metastatic melanoma and metastatic Merkel cell carcinoma.

Our Product: YCANTH (VP-102) for the Treatment of Molluscum

YCANTH (VP-102) is the first FDA-approved product for the treatment of molluscum and its API has been characterized as a NCE, with five years of non-patent regulatory exclusivity associated with that designation. YCANTH (VP-102) is a proprietary drug-device combination of a novel 0.7% w/v topical solution of cantharidin administered through our single-use precision applicator. YCANTH (VP-102) is currently reimbursed either under an assigned permanent J-code (J7354), which was published in April 2024, or under the pharmacy benefit. To date, we have reached approximately 250 million covered lives in the United States through positive insurance payor coverage decisions.

Table of Contents

We have designed YCANTH (VP-102) to address the significant limitations of previously available compounded cantharidin formulations for the treatment of molluscum, with respect to safety, purity, efficacy, stability, and ease of administration. YCANTH (VP-102) contains the first GMP-controlled formulation of cantharidin with a defined pharmaceutical batch process and an API that is greater than 99% pure.

Our proprietary single-use applicator allows for precise application to each lesion. Our applicator contains a sealed glass ampule providing long-term room temperature stability without the changes in concentration due to evaporation, commonly seen in compounded formulations of cantharidin.

Commercial Strategy:

We commercialized YCANTH (VP-102) in the United States by building a specialized sales organization focused on pediatric dermatologists, dermatologists, pediatricians and select other primary care HCPs. In the future, we may commercialize YCANTH (VP-102) for additional geographic regions, independently or with a strategic partner. On March 17, 2021, we entered into the Torii Agreement, pursuant to which we granted Torii an exclusive license to develop and commercialize our product candidates that contain a topical formulation of cantharidin for the treatment of molluscum and common warts in Japan, including YCANTH (VP-102). Additionally, we granted Torii a right of first negotiation with respect to additional indications for the licensed products and certain additional products for use in the licensed field, in each case in Japan.

Marketing Strategy:

We are focused on expanding product awareness and adoption of YCANTH (VP-102) across both healthcare professionals, or HCPs, and consumer segments. HCP marketing initiatives focus on driving adoption through targeted initiatives like peer-to-peer education, data-driven digital advertising, and customized sales representative programs tailored to practice needs such as understanding insurance coverage and product acquisition. Consumer marketing initiatives focus on disease education and awareness of YCANTH as the only HCP-administered, FDA-approved treatment option through social media and print advertising.

Sales and Distribution Strategy:

We have built a specialized sales organization in the United States focused on pediatric dermatologists, dermatologists, pediatricians, and select other primary care HCPs.

We believe our scientifically oriented, customer-focused team currently comprising approximately 40 field sales representatives and contractors allows us to reach the pediatric dermatologists and high decile dermatologists, pediatricians, and primary care HCPs in the United States as potential users of YCANTH (VP-102).

Physicians obtain YCANTH (VP-102) in two primary ways: 1) through a "white bag" service from retail independent or specialty pharmacies or 2) on a buy and bill basis through our wholesale distribution partners. In the fourth quarter of 2025, we launched YCANTH-Rx, a non-dispensing pharmacy, in order to streamline and simplify the provider experience by allowing offices to send YCANTH prescriptions to the same place, regardless of the patient's insurance coverage, for triage to an in-network dispensing pharmacy.

Market Access:

Our cross functional, payer and reimbursement account team has focused efforts in all channels, including, commercial, Medicaid and Managed Medicaid. Since launch, the team has secured coverage for YCANTH (VP-102) in approximately 250 million lives in the United States, with assignment to either the pharmacy benefit or medical benefit. Following the review of our application to Centers for Medicare & Medicaid Services, or CMS, Healthcare Common Procedure Coding System, or HCPCS, Application and the fourth quarter 2023 Drug and Biological HCPCS code application review cycle YCANTH (VP-102) we received a new HCPCS Level II code J7354, "Cantharidin for topical administration, 0.7%, single unit dose applicator (3.2 mg)" with an effective date of April 1, 2024.

Manufacture of Commercial Supply:

We do not have any manufacturing facilities. We rely on, and expect to continue to rely on, third parties for the manufacture of YCANTH (VP-102) and our product candidates for preclinical studies, clinical trials and for the

Table of Contents

commercial supply of our drug products. Manufacturing of the API for YCANTH (VP-102) and our cantharidin-based product candidates require a raw material that is derived from a natural source.

To date, we have obtained naturally-sourced cantharidin directly or indirectly from our supplier based in the People’s Republic of China. On July 16, 2018, we entered into a Supply Agreement, or the Supply Agreement, with Funing County Development Brucea Javanica Professional Cooperatives, or the Supplier, pursuant to which the Supplier has agreed to supply naturally-sourced cantharidin to us for a specified fixed price. Pursuant to the Supply Agreement, the Supplier agreed that it will not supply cantharidin, any beetles or other raw material from which cantharidin is derived to any other customer in North America, subject to specified minimum annual purchase orders and forecasts. However, as we did not purchase the specified minimum for the year ended December 31, 2024, this exclusivity provision no longer applies. As of December 31, 2025, we held inventories of approximately 150,000 finished drug product applicators in various stages of completion. With regards to the cantharidin API, we possessed total inventories in a combination of raw cantharidin and GMP API adequate to produce over 17 million additional finished drug product applicators in the United States. Our drug product contract manufacturers and primary packaging vendor are all US-based, FDA-registered establishments and have a history of supplying products to the pharmaceutical industry.

Competition:

The key competitive advantages of YCANTH (VP-102) are derived from its efficacy, safety, convenience, pricing, and stability. With respect to YCANTH (VP-102) for the treatment of molluscum, we are primarily competing with historical tendency of HCPs to watch-and-wait along with remedies such as unapproved topical products, natural oils, off-label drugs, natural remedies and compounded unstandardized cantharidin along with certain procedures including curettage, cryotherapy, and laser surgery.

In January 2024, the FDA also approved ZelsuvmiTM (berdazimer gel) for the treatment of molluscum in patients 1 year and older. Zelsuvmi launched in July 2025 and is prescribed for at-home use to be applied by a patient or caregiver once daily for up to 12 weeks.

Clinical Development Programs

YCANTH (VP-102) for the Treatment of Common Warts

We are also developing YCANTH (VP-102) for the treatment of common warts. Published studies and clinical use provide support for cantharidin as a safe and effective treatment for common warts. We believe that YCANTH (VP-102) has the potential to address many of the shortcomings associated with current therapies, including pain and discomfort, scarring, and lack of effectiveness. In addition, we believe YCANTH’s (VP-102) convenient ease of administration will differentiate it from existing alternative unapproved therapies.

We conducted an open-label Phase 2 clinical trial (COVE-1) to evaluate the efficacy, safety, and tolerability of YCANTH (VP-102) in subjects with up to six common warts. In this study, there were two cohorts. Cohort 1 was conducted at a single site with 21 subjects aged 2 years and older receiving up to 4 treatments with YCANTH (VP-102) at least 14 days between treatments with longer treatment intervals allowed at the discretion of the investigator depending on a specific subject’s clinical response. Cohort 2 was conducted at four sites with 35 subjects age 12 years and older receiving up to 4 treatments with YCANTH (VP-102) every 21 days. Paring of warts, a technique commonly used by dermatologists to prepare the wart for treatment, was allowed in Cohort 2 to remove any adherent thick scale from a wart prior to application of YCANTH (VP-102). The primary objective of both cohorts was to evaluate the efficacy of up to 4 dermal applications of YCANTH (VP-102) when applied to common warts by assessing the proportion of subjects achieving complete clearance of all treatable warts at Day 84. Complete clearance of warts at Day 84 for Cohort 1 was observed in 19.0% of subjects, and for Cohort 2 complete clearance was observed in 51.4% of subjects. By Day 84, there was a mean decrease from baseline in the number of warts of 31.2% for Cohort 1 subjects and 53.8% for Cohort 2 subjects. In both cohorts, the most frequently reported adverse events were anticipated application site skin reactions that were primarily mild or moderate in intensity, including vesicles, pain, erythema, pruritus, scabbing, dryness, edema, and post-inflammatory pigmentation changes. There were no deaths or serious adverse events reported, and there were no adverse events leading to trial drug discontinuation.

Trial and Status Formulation Trial Design Trial Objectives

Based on results of our Phase 2 trial, we designed a Phase 3 program of YCANTH (VP-102) for the treatment of common warts. We held a Type C meeting with FDA on our clinical development plan for YCANTH (VP-102) common warts indication on November 6, 2023. The meeting resulted in gaining alignment on the design of a pivotal Phase 3 clinical development plan to evaluate YCANTH (VP-102) for the treatment of common warts. The Phase 3 program commenced in late 2025, with the first patient dosed in the United States in December 2025.

VP-315 for the Treatment of Basal Cell Carcinoma (BCC)

We are developing our product candidate, VP-315, for the treatment of BCC and potentially additional dermatological oncology indications. The FDA accepted our IND in November 2021. We dosed the first patient in a Phase 2 trial of VP-315 in BCC in April 2022. The Phase 2 trial was a three-part, open-label, multicenter, dose-escalation, proof-of-concept trial of VP-315 when administered intratumorally to adults with biopsy-proven BCC. Part 1 of the trial was designed to evaluate VP-315’s safety profile when administered in escalating doses to individual subjects. Part 2 was designed to confirm the exploratory dose from Part 1 and determine the optimal therapeutic regimen.

We enrolled 10 patients in Part 1 of the trial. In Part 1, VP-315 demonstrated a favorable safety and tolerability profile with no reported serious adverse events. We initiated Part 2 of the trial in April 2023. In June 2023, the protocol was amended to remove an originally anticipated Part 3 of the trial by expanding Part 2. We dosed the last patient in December 2023.

In total, the trial enrolled 92 adult subjects with a histological diagnosis of BCC in at least one eligible target lesion. Both clinical and histological clearance of treated lesion(s) at excision were assessed. Part 2 efficacy data showed that approximately 51% of tumors achieved complete histologic clearance. All tumors treated had a reduction in tumor size. Overall tumor size reduction was 86%. Tumor size reduction in subjects who still had any residual tumor was 71%. The most frequently reported treatment emergent adverse events, or TEAEs, were typically mild or moderate in severity. Most TEAEs that were considered related to study drug were temporary and anticipated as part of the response to treatment. The most frequently reported TEAEs related to the study treatment were documented as expected on the Cutaneous Reaction Assessment form as erythema, induration, swelling, blister formation, desquamation, erosion, ulceration, and necrosis. There were no serious or life-threatening TEAEs or TEAEs leading to death in the study.

In November 2024, we also reported additional data based upon a post-hoc analysis of the data from the Study and announced a calculated ORR (defined as the percentage of study subjects who do not demonstrate disease progression and who experience at least a 30% level of tumor reduction along with partial or complete response following treatment) of 97%.

In November 2025, we presented additional data at the Society for Immunotherapy of Cancer 40th Annual Meeting, which showed that VP-315 induced a robust local immune response with both cell-mediated and humoral components, effectively shifting the tumor microenvironment from an immunosuppressive to an anti-tumor state, and additional data regarding the histologic assessment in non-injected lesions that suggests a potential abscopal-like effect. Since that presentation, we continued to evaluate the abscopal response in 14 observed but not treated lesions in the Phase 2 study, noting that 3 out of these 14 lesions had complete histologic clearance and there was a 67% overall reduction in

10

Table of Contents

tumor size across all 14 lesions. If this overall product profile could be demonstrated in pivotal Phase 3 testing, we believe VP-315 has the potential to emerge as a non-surgical, immunotherapy treatment option for basal cell carcinoma and other skin cancers.

In March 2025, we also obtained feedback from the FDA from the end-of-Phase 2 (EOP2) meeting that supports an efficient Phase 3 program and path to registration for VP-315. This includes two Phase 3 studies of approximately 100 subjects each in placebo-controlled studies with a primary endpoint of complete clearance at week 14. Additional long-term follow up studies will all be deferred to post approval commitments. We believe these data, coupled with the EOP2 regulatory feedback, further support the clinical efficacy and histologic clearance observed in the Phase 2 BCC trial. These data also help inform next steps for the advancement of the VP-315 Program into Phase 3 clinical trials and we are evaluating the cost and logistics for the initiation of the VP-315 Program. We may explore non-dilutive strategic partnerships to help fund the development and commercialization of VP-315.

Competition for Pipeline Products

The pharmaceutical industry is subject to rapidly advancing technologies, intense competition, and a strong emphasis on proprietary products. We face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, compounding facilities, academic institutions, governmental agencies, and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with existing treatments and new treatments that may become available in the future.

With respect to YCANTH (VP-102) for common warts, we will primarily be competing with over-the-counter products, cryotherapy, curettage, laser surgery, or other off-label therapies. There are currently no FDA-approved prescription pharmaceutical therapies for the treatment of common warts.

We are aware of several other product candidates in development as potential treatments for the indications we intend to target for YCANTH. There are a number of other companies developing products for common warts. In addition, other drugs have been used off-label as treatments for common warts.

With respect to VP-315, multiple companies are developing therapies for BCC across various stages of clinical development. While surgery remains the historical standard of care for superficial and nodular BCC, there is increasing interest in non-surgical alternatives given the potential for disfigurement and procedure-related morbidity, including infection, pain and scarring. Several companies are actively conducting clinical trials in superficial and nodular BCC. In addition, companies with FDA-approved therapies for advanced and metastatic cancers are pursuing label expansions to include locally advanced and metastatic BCC, and at least one such company is evaluating its agent in early-stage BCC clinical studies.

Intellectual Property

YCANTH (VP-102) for molluscum, VP-315 for dermatological oncology, and other product candidates

In addition to our five-year regulatory exclusivity for YCANTH (VP-102), the extent of our commercial success depends in part on our ability to obtain and maintain proprietary protection for YCANTH (VP-102), including our proprietary cantharidin formulation and applicator, and any of our current or future product candidates (including VP-315 for dermatological oncology), medical devices, synthetic methodologies, novel discoveries, drug development technologies, and 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 policy is to seek to protect our proprietary position by, among other methods, filing and prosecuting U.S. and foreign patent applications related to YCANTH (VP-102) and our product candidates (including VP-315 for dermatological oncology) and other proprietary technologies, inventions, and improvements that are important to the development and implementation of our business. We also rely on trademarks, trade secrets, know-how, continuing technological innovation, and in-licensing opportunities to develop and maintain our proprietary position.

YCANTH (VP-102)

While we seek broad coverage of YCANTH (VP-102) under our pending patent applications, our granted patents and pending patent applications do not include any claims drawn to the active pharmaceutical agent cantharidin per se or for the broad use of our API alone for the treatment of warts or molluscum. However, our granted patents and pending patent applications do claim, for example, our cantharidin formulations, applicator devices and related accessories, dosing

11

Table of Contents

regimens, methods of preparation including methods of synthesis, and methods of use. Despite these patent filings, there is always a risk that modification of the specific formulation, manufacturing process, method of application of cantharidin to the skin, and/or specific method of use may allow a competitor to avoid infringement of our claims. In addition, patents, if granted, will expire, and we cannot provide any assurance that any additional patents will issue from our pending or any future patent applications.

We currently have three issued United States utility patents covering the cantharidin formulation of YCANTH (VP-102), applicator devices and systems comprising the formulation, and methods of using the same, e.g., for the treatment of molluscum. The first of these U.S. patents will expire on June 11, 2037 (including 745 days of patent term extension, or PTE, granted by the United States Patent and Trademark Office, or USPTO, on June 6, 2025), and the other two will expire on August 22, 2038. We also have an issued U.S. utility patent covering the YCANTH (VP-102) applicator which will expire on February 19, 2041. Additionally, we have granted patents in Australia, Brazil, Canada, Europe, India, Israel, Japan, South Korea, and Mexico covering our proprietary cantharidin formulations, applicator devices and systems comprising the formulations, and methods of using the same. Additionally, we have granted patents in Australia, Brazil, Canada, China, Israel, Japan, and South Korea, as well as an allowed patent application in Europe, covering the YCANTH (VP-102) applicator.

We also currently have two issued United States design patents covering the design of our YCANTH (VP-102) applicator and one issued United States design patent covering the design of our proprietary ampule crush tool. The two issued U.S. design patents covering the design of our YCANTH (VP-102) applicator will expire on October 27, 2035 and July 23, 2039, and the issued United States design patent covering the design of our proprietary ampule crush tool will expire on April 11, 2038. Additionally, we have granted design patents in Australia, Brazil, Canada, China, Europe, Hong Kong, India, Israel, Japan, South Korea, Mexico, and the United Kingdom covering the design of our proprietary ampule crush tool for use with our YCANTH (VP-102) applicator.

In addition, we currently have three United States patents covering methods of preparing and purifying cantharidin, as well as granted patents in Australia, Brazil, Canada, China, Europe, Hong Kong, India, Israel, Japan, South Korea, and Mexico covering methods of preparing cantharidin. Additionally, we have a granted patent in Japan covering methods of purifying cantharidin.

As of February 16, 2026, we have nationalized seven international PCT patent applications for utility patents related to YCANTH (VP-102), six of which have been nationalized in the United States, Australia, Brazil, Canada, China, Europe, Israel, India, Japan, South Korea, and Mexico, and one of which has been nationalized in the United States, Europe, and Japan. Six of these European patent applications have been registered in Hong Kong. These patent applications relate to YCANTH (VP-102), including our proprietary cantharidin formulation and applicator, and other inventions related to YCANTH (VP-102). Our patent applications related to YCANTH (VP-102) include claims relating to (i) our specific formulations and preparations of YCANTH (VP-102), (ii) the design of our proprietary applicator, including both the general design and specific design elements, (iii) claims related to safety features included in the YCANTH (VP-102) formulation, including colorants and bittering agents, (iv) methods of administration of YCANTH (VP-102) for the treatment of skin lesions, and (v) our proprietary ampule crush tool for use with our YCANTH (VP-102) applicator, (vi) methods for the synthesis of cantharidin, (vii) methods for purifying cantharidin and (viii) methods for detecting impurities in cantharidin. Excluding any patent term adjustment and/or patent term extension, any additional utility patents to issue from these patent applications are projected to expire between 2034 and 2041. We cannot provide any assurance as to whether any additional patents will issue from these patent applications or, if any patents do issue, the scope of the claims that will be granted.

VP-315

Pursuant to the Lytix Agreement, we have in-licensed U.S. and international patents and patent applications covering the active pharmaceutical agent of VP-315, formulations thereof, and methods of use. In addition, we have filed an international PCT application and a U.S. non-provisional utility patent application covering our clinical protocol for administering VP-315 for the treatment of skin cancers including BCC. Excluding any patent term adjustment and/or patent term extension, any U.S. or foreign utility patents to issue from our PCT application covering our clinical protocol for administering VP-315 are projected to expire on April 12, 2044; and excluding any patent term adjustment and/or patent term extension, any U.S. utility patents to issue from our U.S. non-provisional utility patent application covering our clinical protocol for administering VP-315 are projected to expire on January 24, 2045. While we seek to protect our clinical protocol for administering VP-315 under our pending patent applications, we cannot provide any assurance as to

12

Table of Contents

whether any patents will issue from these patent applications or, if any patents do issue, the scope of the claims that will be granted.

Patent Term

Individual patents extend for varying periods depending on the date of filing of the patent application or the date of patent issuance and the legal term of patents in the countries in which they are obtained. Generally, utility patents issued from applications in the United States are granted for a term of 20 years from the earliest effective non-provisional filing date. In addition, in certain instances, a patent’s term can be adjusted to recapture a portion of the USPTO's delay in examining and issuing the patent, and extended to recapture a portion of the patent term effectively lost as a result of the FDA regulatory review period of the drug covered by the patent. However, as to the FDA component, the restoration period cannot be longer than five years, the total patent term including the restoration period must not exceed 14 years following FDA approval of the drug, and the extension may only apply to one patent that covers the approved drug (and to only those patent claims covering the approved drug or a method for using it). There can be no assurance that any such patent term adjustment or extension will be obtained. The duration of foreign patents varies in accordance with provisions of applicable local law, but typically is also 20 years from the earliest effective non-provisional filing date. However, the actual protection afforded by a patent varies on a product-by-product basis, from country to country and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory-related extensions, the availability of legal remedies in a particular country, and the validity and enforceability of the patent.

Confidentiality

Furthermore, we rely upon trade secrets, know-how, and continuing technological innovation to develop and maintain our competitive position. We seek to protect our proprietary information, in part, using confidentiality agreements with our commercial partners, collaborators, employees, and consultants and invention assignment agreements with our employees. We also have confidentiality agreements and/or invention assignment agreements with our commercial partners and selected consultants. These agreements are designed to protect our proprietary information and, in the case of the invention assignment agreements, to grant us ownership of technologies that are developed through a relationship with a third party. These agreements may be breached, and we may not have adequate remedies for any such breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our commercial partners, collaborators, employees, and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Torii Collaboration and License Agreement

In August 2020, we entered into an option agreement with Torii for the development and commercialization of our product candidates for the treatment of molluscum and common warts in Japan, including YCANTH (VP-102), or the Option Agreement. Torii paid us $0.5 million to secure the exclusive option.

On March 2, 2021, Torii exercised the exclusive option in the Option Agreement. On March 17, 2021, we entered into the Torii Agreement with Torii, pursuant to which we granted Torii an exclusive license to develop and commercialize our product candidates that contain a topical formulation of cantharidin for the treatment of molluscum and common warts in Japan, including YCANTH (VP-102). Additionally, we granted Torii a right of first negotiation with respect to additional indications for the licensed products and certain additional products for use in the licensed field, in each case in Japan.

Under the Torii Agreement, Torii is responsible for all development activities and specified costs in support of obtaining regulatory approval of the licensed products in Japan, provided that Torii’s activities will be overseen by a joint steering committee. Torii is required to use commercially reasonable efforts to conduct all development necessary to obtain regulatory approval for licensed products in Japan, to obtain and maintain such approvals, and to commercialize licensed products upon receipt of such approvals.

From the inception of the Torii Agreement through December 31, 2025, we have received $38.0 million in milestone revenue from Torii. We are entitled to receive from Torii up to $32.0 million in aggregate payments contingent on achievement of specified regulatory and sales milestones, in addition to tiered transfer price payments for supply of product in the percentage range of the mid-30s to the mid-40s of net sales. The transfer payments shall be payable, on a product-by-product basis, beginning on the first commercial sale of such product and ending on the latest of (a) expiration of the last-to-expire valid claim contained in certain licensed patents in Japan that cover such product, (b) expiration of

13

Table of Contents

regulatory exclusivity for the first indication for such product in Japan, and, (c) (i) with respect to the first product, ten years after first commercial sale of such product, and, (ii) with respect to any other product, the later of (x) ten years after first commercial sale of the first product and (y) five years after first commercial sale of such product. See discussion of the Second Amendment below for detail on the planned transfer of manufacturing for the Japanese market to Torii.

On March 7, 2022, pursuant to the Torii Agreement, we entered into a Clinical Supply Agreement with Torii, whereby we are obligated to supply product to Torii for use in clinical trials and other development activities. We recognized billed and unbilled license and collaboration revenue of $2.3 million and $1.0 million for the years ended December 31, 2025 and 2024, respectively related to supplies and development activity pursuant to this agreement.

The Torii Agreement expires on a product-by-product basis upon expiration of Torii’s obligation under the agreement to make transfer price payments for such product. Torii has the right to terminate the agreement upon specified prior written notice to us. Additionally, either party may terminate the agreement in the event of an uncured material breach of the agreement by, or insolvency of, the other party. We may terminate the agreement in the event that Torii commences a legal action challenging the validity, enforceability or scope of any licensed patents.

On May 14, 2024, we entered into the First Amendment pursuant to which, we and Torii will equally split the cost of the Program, with Torii paying all of the costs when due and we will repay Torii the Company Portion. The Company Portion accrues interest annually at the greater of (i) the one-month SOFR plus 2% and (ii) 6%. Torii has the right to offset the Company Portion plus applicable interest against certain of the milestone-based payments that would otherwise be due to us under the terms of the Torii Agreement. In addition, if Torii has not received payment or other recoupment in full of the Company Portion plus applicable interest within 60 months after the date on which Torii made its first payment for the Program costs, Torii may invoice us for the remaining Company Portion plus applicable interest. Torii may recoup our share of the costs plus applicable interest against certain development milestone payments in the Torii Agreement.

In conjunction with the First Amendment, we issued Torii a warrant to purchase up to 50,000 shares of our common stock at an exercise price per share of $95.60. The warrant has a term of ten years and is exercisable only with respect to the shares that have vested as of the date of exercise. The shares underlying the warrant vested one-third in December 2025 when the first patient was dosed in the Program, with the remaining vesting occurring one-third on the date that the database lock with respect to the Program occurs and one-third on the date the Company submits a new drug application to the FDA for YCANTH (VP-102) for the treatment of common warts.

On June 27, 2025, we entered into the Second Amendment, which further revised the details of the cost sharing arrangement initially negotiated as part of the First Amendment. The Second Amendment, among other things, provided for the acceleration of an $8.0 million milestone fee payment that was received by us in July 2025. Pursuant to the Second Amendment, in September 2025, Torii also paid to us a $10.0 million milestone payment upon the approval of TO-208, referred to as YCANTH in the U.S., for molluscum in Japan, in cash, rather than as an offset to costs of the Program as originally contemplated under the First Amendment. Torii will be paying the first $40.0 million of out-of-pocket costs when due, with Verrica repaying to Torii half of such costs over time. Consistent with the First Amendment, to repay its portion of the costs of the Program, we will offset amounts otherwise due from Torii for certain transfer price payments, future royalties and remaining development milestones. To the extent the cost of the Program exceeds $40.0 million, we will pay such excess costs, up to a specified maximum amount, and Torii will repay to us half of such costs. The Second Amendment also sets forth that we will initiate a manufacturing transfer to Torii, which is expected to take several years, that will allow Torii to produce YCANTH (TO-208) applicators to be sold in Japan. In the interim, Torii will continue to purchase applicators from us. After the transfer of at least one component of the manufacturing process, we will begin earning royalties related to net sales in Japan of applicators manufactured by Torii and/or its manufacturing partners in lieu of the transfer price for completed applicators.

Lytix License Agreement

On August 7, 2020, we entered into the Lytix Agreement, pursuant to which we obtained a worldwide, exclusive, royalty-bearing license, with the right to sublicense, for certain technology of Lytix to research, develop, manufacture, have manufactured, use, sell, have sold, offer for sale, import and otherwise commercialize VP-315 for use in all malignant and pre-malignant dermatological indications, other than metastatic melanoma and metastatic Merkel cell carcinoma. Our right to manufacture the active pharmaceutical ingredient is limited to certain instances, and Lytix is obligated to manufacture and supply our clinical and commercial needs for such active pharmaceutical ingredient. We are obligated to use commercially reasonable efforts to develop and to commercialize the product, which development and commercialization will be overseen by a joint steering committee. Lytix has agreed not to pursue any products in the field of dermatology other than VP-315 for use in metastatic melanoma and metastatic Merkel cell carcinoma. Lytix has granted us an exclusive

14

Table of Contents

option to negotiate for an exclusive license for use of the active ingredient in VP-315 in additional dermatological indications.

In connection with entering the Lytix Agreement, we made an initial payment of $0.3 million. We made additional payments of $2.3 million in February 2021 and $1.0 million in May 2022 upon the achievement by Lytix of a regulatory milestone. Additionally, we are obligated to pay up to $111.0 million contingent on achievement of specified development, regulatory, and sales milestones, and tiered royalties based on worldwide annual net sales ranging in the low double digits to the mid-teens, subject to certain customary reductions. Our obligation to pay royalties expires on a country-by-country and product-by-product basis based on the later of the expiration or abandonment of the last to expire licensed patent covering the active ingredient of VP-315 anywhere in the world and expiration of regulatory exclusivity for VP-315 in such country. Additionally, all upfront fees and milestone-based payments received by us from a sublicensee will be treated as net sales and will be subject to the royalty payment obligations under the Lytix Agreement, and all royalties received by us from a sublicensee shall be shared with Lytix at a rate that was initially 50% but decreases based on the stage of development of VP-315 at the time such sublicense is granted.

The Lytix Agreement expires on a product-by-product and a country-by-country basis upon expiration of the royalty term for such product in such country. At any time after the first anniversary of the execution of the Lytix Agreement, we have the right to terminate the agreement, either on a region-by-region basis or in its entirety, upon specified written notice to Lytix. Lytix may terminate the agreement, either on a region-by-region basis or in its entirety, if we develop or commercialize a competing product in the licensed field, or in its entirety if we challenge the validity, enforceability or scope of any licensed patent, subject in each case to certain cure rights. Either party may terminate the Lytix Agreement in the event of an uncured material breach or insolvency of the other party.

Government Regulation and Product Approval

Government authorities in the United States, at the federal, state and local levels, and in other countries, extensively regulate, among other things, the research, development, testing, manufacture, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, import and export of pharmaceutical products, such as those we are developing. We, along with third-party contractors, are required to navigate the various chemistry, manufacturing and controls, preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval of our product candidates. The processes for obtaining regulatory approvals in the United States and in foreign countries, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources.

United States Government Regulation

In the United States, the FDA regulates drugs under the FDCA and its implementing regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable United States requirements at any time during the drug development process, approval process or after approval, may subject an applicant to a variety of administrative or judicial sanctions, such as the FDA’s refusal to approve pending new drug applications, or NDAs, withdrawal of an approval, imposition of a clinical hold, issuance of warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

The process required by the FDA before a drug may be marketed in the United States generally involves:

•completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s good laboratory practice, or GLP, regulations;

•submission to the FDA of an IND, which must become effective before human clinical trials may begin;

•approval by an independent institutional review board, or IRB, at each clinical site before each clinical trial may be initiated;

•performance of adequate and well-controlled clinical trials in accordance with good clinical practice, or GCP, requirements to establish the safety and efficacy of the proposed drug for each indication;

•submission to the FDA of a new drug application, or NDA, together with payment of the applicable user fee;

15

Table of Contents

•satisfactory completion of an FDA advisory committee review, if applicable;

•satisfactory completion of chemistry, manufacturing and controls testing, an FDA inspection of the manufacturing facility or facilities at which the product is produced to assess compliance with cGMP requirements, and to assure that the facilities, methods and controls are adequate to preserve the drug’s identity, strength, quality and purity;

•satisfactory completion of an FDA inspection of selected clinical sites to assure compliance with GCPs and the integrity of the clinical data; and

•FDA review and approval of the NDA.

Preclinical Studies

Preclinical studies include laboratory evaluation of product chemistry, toxicity and formulation, as well as animal studies to assess potential safety and efficacy. An IND sponsor must submit the results of the nonclinical tests, together with manufacturing information, analytical data and any available clinical data or literature, among other things, to the FDA as part of an IND. Some nonclinical testing may continue even after the IND is submitted. An IND automatically becomes effective and a clinical trial proposed in the IND may begin 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to one or more proposed clinical trials and places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence.

Clinical Trials

Clinical trials involve the administration of the investigational new drug to human subjects under the supervision of qualified investigators in accordance with GCP requirements, which include the requirement that all research subjects provide their informed consent in writing for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, an institutional review board, or IRB, at each participating clinical site, or a central IRB serving such sites, must review and approve the plan for any clinical trial before it commences, and must continue to oversee the clinical trial while it is being conducted. Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health, or NIH, for public dissemination on their ClinicalTrials.gov website.

Human clinical trials are typically conducted in three sequential phases, which may overlap or be combined. In Phase 1, the drug is initially introduced into healthy human subjects or patients with the target disease or condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and, if possible, to gain an initial indication of its effectiveness. In Phase 2, the drug typically is administered to a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage. In Phase 3, the drug is administered to an expanded patient population, generally at geographically dispersed clinical trial sites, in well-controlled clinical trials to generate enough data to statistically evaluate the safety and efficacy of the product for approval, to establish the overall risk-benefit profile of the product and to provide adequate information for the labeling of the product.

In some cases, the FDA may grant conditional approval of an NDA for a product candidate on the sponsor’s agreement to conduct additional clinical trials after NDA approval. In other cases, a sponsor may voluntarily conduct additional clinical trials post approval to gain more information about the drug. Such post approval trials are typically referred to as Phase 4 clinical trials.

Progress reports detailing the results of the clinical trials must be submitted, at least annually, to the FDA, and more frequently if serious adverse events occur. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or at all. Furthermore, the FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at any participating clinical site if the clinical trial is not being conducted in accordance with the IRB's requirements, or if the drug has been associated with unexpected serious harm to patients.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

Marketing Approval

Assuming successful completion of the required clinical testing, the results of the preclinical studies and clinical trials, together with detailed information relating to the product's chemistry, manufacture, controls data and proposed labeling, among other things, are submitted to the FDA as part of an NDA requesting approval to market the product for one or more indications. In most cases, the submission of an NDA is subject to a substantial application user fee. Under the Prescription Drug User Fee Act, or PDUFA, guidelines that are currently in effect, the FDA has a goal of ten months from the date of "filing" of a standard NDA for a new molecular entity to review and act on the submission. This review typically takes twelve months from the date the NDA is submitted to the FDA because the FDA has sixty days from receipt to make a decision as to whether the application has been accepted for filing.

In addition, under the Pediatric Research Equity Act of 2003 as amended and reauthorized, certain NDAs or supplements to an NDA must contain data that are adequate to assess the safety and effectiveness of the drug for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults, or full or partial waivers from the pediatric data requirements.

The FDA also may require submission of a risk evaluation and mitigation strategy, or REMS, plan to ensure that the benefits of the drug outweigh its risks. The REMS plan could include medication guides, physician communication plans, assessment plans, and/or elements to assure safe use, such as restricted distribution methods, patient registries or other risk minimization tools.

The FDA conducts a preliminary review of all NDAs within the first 60 days after submission, before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA may request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA reviews an NDA to determine, among other things, whether the drug is safe and effective and whether the facility in which it is manufactured, processed, packaged or held meets standards designed to assure the product's continued safety, quality and purity.

The FDA may refer an application for a novel drug to an advisory committee. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical trial sites to assure compliance with GCP requirements.

The testing and approval process for an NDA requires substantial time, effort and financial resources, and each may take several years to complete. Data obtained from preclinical and clinical testing are not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. The FDA may not grant approval of an NDA on a timely basis, or at all.

After evaluating the NDA and all related information, including the advisory committee recommendation, if any, and inspection reports regarding the manufacturing facilities and clinical trial sites, the FDA may issue an approval letter, or, in some cases, a complete response letter. A complete response letter generally contains a statement of specific

17

Table of Contents

conditions that must be met in order to secure final approval of the NDA and may require additional chemistry, manufacturing and controls documentation, clinical or preclinical testing in order for the FDA to reconsider the application. Even with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If and when those conditions have been met to the FDA's satisfaction, the FDA will typically issue an approval letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications.

Even if the FDA approves a product, it may limit the approved indications for use of the product, require that contraindications, warnings or precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution and use restrictions or other risk management mechanisms under a REMS, which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes, and additional labeling claims, are subject to further testing requirements, post approval submission, and FDA review and approval.

Orange Book Listing

In seeking approval for a drug through an NDA, applicants are required to list with the FDA certain patents whose claims cover the applicant's product. Upon approval of an NDA, each of the patents listed in the application for the drug is then published in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations, known as the Orange Book. Any applicant who files an Abbreviated New Drug Application, or ANDA, seeking approval of a generic equivalent version of a drug listed in the Orange Book or a 505(b)(2) NDA referencing a drug listed in the Orange Book must certify, for each patent listed in the Orange Book for the referenced drug, to the FDA that (1) no patent information on the drug product that is the subject of the application has been submitted to the FDA, (2) such patent has expired, (3) the date on which such patent expires or (4) such patent is invalid or will not be infringed upon by the manufacture, use or sale of the drug product for which the application is submitted. The fourth certification described above is known as a paragraph IV certification. A notice of the paragraph IV certification must be provided to each owner of the patent that is the subject of the certification and to the holder of the approved NDA to which the ANDA refers. The applicant may also elect to submit a "section viii" statement certifying that its proposed label does not contain (or carves out) any language regarding the patented method-of-use rather than certify to a listed method-of-use patent. This section viii statement does not require notice to the patent holder or NDA owner. There might also be no relevant patent certification.

If the reference NDA holder and patent owners assert a patent challenge directed to one of the Orange Book listed patents within 45 days of the receipt of the paragraph IV certification notice, the FDA is prohibited from approving the application until the earlier of 30 months from the receipt of the paragraph IV certification expiration of the patent, settlement of the lawsuit, or a decision in the infringement case that is favorable to the applicant. Even if the 45 days expire, a patent infringement lawsuit can be brought and could delay market entry, but it would not extend the FDA-related 30-month stay of approval.

The ANDA or 505(b)(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the branded reference drug has expired. Specifically, the holder of the NDA for the listed drug may be entitled to a period of non-patent exclusivity, during which the FDA cannot approve an ANDA or 505(b)(2) application that relies on the listed drug. For example, a pharmaceutical manufacturer may obtain five years of non-patent exclusivity upon NDA approval of a New Chemical Entity, or NCE, which is a drug that contains an active moiety that has not been approved by FDA in any other NDA. An "active moiety" is defined as the molecule or ion responsible for the drug substance's physiological or pharmacologic action. During the five-year exclusivity period, the FDA cannot accept for filing any ANDA seeking approval of a generic version of that drug or any 505(b)(2) NDA for the same active moiety and that relies on the FDA's findings regarding that drug, except that FDA may accept an application for filing after four years if the follow-on applicant makes a paragraph IV certification. This exclusivity period may be extended by an additional six months if certain requirements are met to qualify the product for pediatric exclusivity, including the receipt of a written request from the FDA that we conduct certain pediatric studies, the submission of study reports from such studies to the FDA after receipt of the written request and satisfaction of the conditions specified in the written request.

Post-Approval Requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications, manufacturing changes or other labeling claims, are subject to further testing requirements and prior FDA review and approval. There also are continuing annual program fee requirements for any marketed products.

Even if the FDA approves a product, it may limit the approved indications for use of the product, require that contraindications, warnings or precautions be included in the product labeling, including a boxed warning, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms under a REMS, which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance programs.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and state agencies and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance with cGMP requirements. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon the sponsor and any third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance.

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market or if requested by the Sponsor. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in mandatory revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential FDA enforcement actions include, among other things:

•restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

•fines, warning letters or holds on post-approval clinical trials;

•refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product approvals;

•product seizure or detention, or refusal to permit the import or export of products; or

•injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label, although physicians, in the practice of medicine, may prescribe approved drugs for unapproved indications. Companies may also share truthful and not misleading information that is otherwise consistent with the labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. However, physicians may, in their independent medical judgement, prescribe legally available products for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments but the FDA does restrict manufacturer's communications on the subject of off-label use of their products. Promotional materials distributed by companies must be submitted to the FDA on the date of first use.

In addition, the distribution of prescription pharmaceutical products is subject to the Drug Supply Chain Security Act and state laws that limit the distribution of prescription pharmaceutical product samples and impose requirements to ensure accountability in distribution.

Regulation of Compounding Pharmacies

Compounding is a practice in which a licensed pharmacist, a licensed physician, or in the case of an outsourcing facility, a person under the supervision of a licensed pharmacist, combines, mixes, or alters ingredients of a drug to create a medication tailored to the needs of an individual patient. Although we are not engaged in compounding, the active pharmaceutical ingredient in YCANTH (VP-102) has historically been used in the compounding of topical pharmaceutical products, and we could be subject to competition by compounders subject to the requirements set forth in Sections 503A and 503B of the FDCA.

Section 503A of the FDCA exempts licensed pharmacists or licensed physicians who compound products for identified, individual patients, based on the receipt of a valid prescription order, from the FDCA's new drug approval requirements, cGMP requirements, and the requirement to label products with adequate directions for use, provided certain conditions are met. These conditions include that the pharmacist or physician does not compound regularly or inordinate amounts any drug product that is essentially a copy of a commercially available drug product, unless there is a difference between the compounded product and the commercially available product that is made for an individual patient, and which the prescribing practitioner determines produces a significant difference for that patient. The FDA has interpreted this prohibition to mean that the compounding of a product with the same active pharmaceutical ingredient as a commercially available drug, that has the same, similar, or an easily substitutable dosage strength as the commercially available drug, and that can be used by the same route of administration as the commercially available drug, cannot be conducted under Section 503A usually, very often, or at regular times or intervals, or more frequently or in larger quantities than needed to address unanticipated emergency circumstances, unless the limited exception described above applies.

In addition, compounding under Section 503A may only use bulk drug substances that appear on a list issued by FDA through regulations, and/or that comply with certain other conditions specified in the statute.

Unlike Section 503A, Section 503B of the FDCA allows certain entities to compound drugs that are not necessarily prepared in response to prescriptions for identified, individual patients. Such facilities must register with the FDA as outsourcing facilities, and once registered (including payment of a fee), the outsourcing facility must meet certain conditions in order to be exempt from the FDCA's approval requirements and the requirement to label products with adequate directions for use. Under Section 503B, a drug must be compounded in compliance with cGMP, by or under the direct supervision of a licensed pharmacist in order to be so exempt. The outsourcing facility must also report specific information about the products that it compounds, including a list of all of the products it compounded during the previous six months, and information about the compounded products, such as the source of the active ingredients used to compound pursuant to Section 503B(b)(2). If the outsourcing facility compounds using bulk drug substances, the bulk drug substances must either appear on a list established by the FDA of bulk drug substances for which there is a clinical need or be used to compound drugs that appear on a list established by the FDA of drugs for which there is a shortage. Although the FDA has not yet established a list of bulk drug substances for which there is a clinical need, the FDA has announced an interim policy pursuant to which bulk drug substances may be nominated for inclusion on such list and, provided certain conditions are met, outsourcing facilities may compound with such bulk drug substances pending evaluation of the substances for inclusion on the FDA's list of bulk drug substances for which there is a clinical need. Cantharidin is currently listed among those nominated substances for which bulk drug substance may be used in compounding by outsourcing facilities pending FDA's evaluation. In January 2025, the FDA issued Guidance for Industry addressing the criteria by which the FDA intends to evaluate whether there exists a clinical need for compounding with a bulk drug substance, including, in the case of a bulk drug substance that is a component of an FDA-approved drug, an evaluation of whether there exists an attribute of the approved drug that makes it medically unsuitable to treat certain patients; whether the drug product proposed to be compounded is intended to address that attribute; and whether the drug product proposed to be compounded must be compounded from a bulk drug substance rather than from the finished, FDA-approved drug product. An outsourcing facility would need to satisfy these criteria before being permitted to compound a cantharidin product using bulk cantharidin.

In addition, an outsourcing facility must meet other conditions described in Section 503B, including reporting adverse events and labeling compounded products with certain information. Registered outsourcing facilities are prohibited from selling compounded drugs through a wholesale distributor, or from compounding drugs that are essentially copies of FDA-approved drugs. A drug is "essentially a copy of an approved drug" if it is identical or nearly identical to an approved drug, which the FDA has interpreted to mean that it has the same active ingredient(s), route of administration, dosage form, dosage strength and excipients as the approved drug, or if it has the same active ingredient as an approved drug and there is not a change from the approved drug that produces a clinical difference for an individual patient, as determined by the prescribing practitioner. Registered outsourcing facilities are subject to FDA inspection, and FDA conducts inspections on a risk-based frequency under Section 503B(b)(4) of the FDCA.

Federal and State Fraud and Abuse, Data Privacy and Security, and Transparency Laws and Regulations

In addition to FDA restrictions on marketing of pharmaceutical products, federal and state healthcare laws and regulations restrict business practices in the biopharmaceutical industry. These laws may impact, among other things, our current and future business operations, including our clinical research activities, and proposed sales, marketing and education programs and constrain the business or financial arrangements and relationships with healthcare providers and other parties through which we market, sell and distribute our products for which we obtain marketing approval. These laws include anti-kickback and false claims laws and regulations, data privacy and security, and transparency laws and regulations, including, without limitation, those laws described below.

The federal Anti-Kickback Statute prohibits, among other things, individuals or entities from knowingly and willfully offering, paying, soliciting or receiving remuneration, directly or indirectly, overtly or covertly, in cash or in kind to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term "remuneration" has been broadly interpreted to include anything of value. The federal Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, formulary managers, and other individuals and entities on the other hand. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly and require strict compliance to offer protection. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor.

In addition, a person or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. Further, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act and the civil monetary penalties statute.

The federal civil and criminal false claims laws, including the False Claims Act, prohibit, among other things, any individual or entity from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. A claim includes "any request or demand" for money or property presented to the U.S. government. Several pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of products for unapproved, and thus non-reimbursable, uses.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal statutes that prohibit, among other things, knowingly and willfully executing or attempting to execute a scheme to defraud any healthcare benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their respective implementing regulations, impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization on certain health plans, healthcare clearinghouses and certain healthcare providers, known as covered entities, and their respective business associates, independent contractors that perform certain services involving the use or disclosure of individually identifiable health information and their subcontractors that use, disclose, access, or otherwise process individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorneys' fees and costs associated with pursuing federal civil actions.

The federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children's Health Insurance Program, with specific exceptions, to report annually to CMS information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists, and chiropractors), teaching hospitals, and other

21

Table of Contents

health care professionals (such as physician assistants and nurse practitioners), as well as information regarding ownership and investment interests held by physicians and their immediate family members.

We may also be subject to state and foreign law equivalents of each of the above federal laws; state laws that require manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; state laws that require pharmaceutical companies to comply with the pharmaceutical industry's voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, or that otherwise restrict payments that may be made to healthcare providers; state laws that require reporting of information related to drug pricing; state and local laws that require the registration of pharmaceutical sales representatives; as well as state and foreign laws that govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating in government funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm and the curtailment or restructuring of our operations. To the extent that any of our products are sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.

Coverage and Reimbursement

Market acceptance and sales of any drug products depend in part on coverage and the extent to which adequate reimbursement for drug products is available from third-party payors, including government health administration authorities, managed care organizations and other private health insurers. Coverage and reimbursement for our product also depends on coverage and adequate reimbursement for the procedures using YCANTH (VP-102). A decision by a third-party payor not to cover or separately reimburse for our products could reduce physician utilization of our products. Additionally, in the United States, there is no uniform policy of coverage and reimbursement among third-party payors. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided is made on a payor-by-payor basis. One payor's determination to provide coverage for a drug product does not assure that other payors will also provide coverage, and adequate reimbursement.

CMS has issued a permanent Healthcare Common Procedure Coding System, or HCPCS, Level II code, or J-code, (J7354) for YCANTH, as an FDA-approved treatment for molluscum. Under the HCPCS process, the J-code for YCANTH was published April 1, 2024. J-codes are reimbursement codes used by commercial insurance plans, Medicare, Medicare Advantage, and other government payors for physician-administered drugs and are intended to simplify the claims submission and documentation process, facilitating access for patients.

Additionally, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries, presidential executive orders and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. For example, the U.S. Department of Health and Human Services, or HHS, imposes rebates on many Medicare Part B and Medicare Part D products to penalize price increases that outpace inflation on an annual basis. In addition, HHS has been empowered to negotiate the price of certain single-source drugs that have been on the market for at least seven (7) years and single-source biologics that have been on the market for at least eleven (11) years covered under Medicare as part of the Medicare Drug Price Negotiation Program. Each year up to twenty (20) products will be selected by HHS for the Medicare Drug Price

22

Table of Contents

Negotiation Program. Products subject to the Medicare Drug Price Negotiation Program are expected to experience a significant reduction in reimbursement from the Medicare program on a per unit basis.

Third-party payors determine which medical procedures they will cover and establish reimbursement levels. Even if a third-party payor covers a particular procedure, the resulting reimbursement payment rates may not be adequate. Patients who are treated in-office for a medical condition generally rely on third-party payors to reimburse all or part of the costs associated with the procedure and may be unwilling to undergo such procedures for a treatment using YCANTH (VP-102) in the absence of such coverage and adequate reimbursement.

Reimbursement by a third-party payor for YCANTH (VP-102) and our product candidates may depend upon a number of factors, including the third-party payor's determination that a procedure is safe, effective, and medically necessary; appropriate for the specific patient; cost-effective; supported by peer-reviewed medical journals; included in clinical practice guidelines; and neither cosmetic, experimental, nor investigational.

Further, from time to time, typically on an annual basis, payment rates are updated and revised by third-party payors. Such updates could impact the demand for YCANTH (VP-102) and our other product candidates to the extent that patients are not separately reimbursed for the cost of the products. An example of payment updates is the Medicare program updates to physician payments, which is done on an annual basis. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.

Impact of Healthcare Reform on our Business

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of drug product candidates, restrict or regulate post-approval activities, and affect the profitable sale of drug product candidates.

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the ACA, was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry.

There have been judicial and Congressional challenges and amendments to certain aspects of the ACA. On August 16, 2022, the Inflation Reduction Act of 2022, or IRA, was signed into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the "donut hole" under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. Additionally, on July 4, 2025, the One Big Beautiful Bill Act, or OBBBA, was signed into law, which narrowed access to ACA marketplace exchange enrollment and declined to extend the ACA enhanced advanced premium tax credits that expired at the end of 2025, which, among other provisions in the law, are anticipated to reduce the number of Americans with health insurance. The OBBBA also is expected to reduce Medicaid spending and enrollment by implementing work requirements for some beneficiaries, capping state-directed payments, reducing federal funding, and limiting provider taxes used to fund the program. Congress is considering proposed legislation intended to further reduce healthcare costs with alternatives to replace the expired ACA subsidies. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. It is unclear how such challenges and the healthcare reform measures of the current administration will impact the ACA and our business.

Other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013, and due to subsequent legislative amendments to the statute, will remain in effect until 2032 unless additional Congressional action is taken. These and other laws may result in additional reductions in Medicare and other healthcare funding, which could have an adverse effect on customers for YCANTH (VP-102) or our product candidates, if approved, and, accordingly, our financial operations.

The current administration is pursuing policies to reduce regulations and expenditures across government agencies including at HHS, the FDA, CMS and related agencies. These actions, presently directed by executive orders or memoranda from the Office of Management and Budget, may propose policy changes that create additional uncertainty for our business. For example, the current administration has announced agreements with pharmaceutical companies that require the drug manufacturers to offer, through a direct-to-consumer platform, U.S. patients and Medicaid programs prescription drug Most-Favored Nation pricing equal to or lower than those paid in other developed nations, with additional mandates for direct-to-patient discounts and repatriation of foreign revenues. Other recent actions, for example, include (1) directing agencies to reduce agency workforce and cut programs; (2) directing HHS and other agencies to lower prescription drug costs through a variety of initiatives, including by improving upon the Medicare Drug Price Negotiation Program and establishing Most-Favored-Nation pricing for pharmaceutical products; (3) imposing tariffs on imported pharmaceutical products; and (4) as part of the Make America Healthy Again Commission's Strategy Report released in September 2025, working across government agencies to increase enforcement on direct-to-consumer pharmaceutical advertising. Additionally, the current administration recently called on Congress to enact "The Great Healthcare Plan," to codify and expand Most-Favored Nation pricing, lower government subsidies to private insurance companies, increase healthcare price transparency, expand pharmaceutical drugs available for over-the-counter purchase, and enact restrictions on pharmacy benefit manager payment methodologies, among other things. These actions and policies may significantly reduce U.S. drug prices, potentially impacting manufacturers' global pricing strategies and profitability, while increasing their operational costs and compliance risks. In June 2024, in Loper Bright Enterprises v. Raimondo, or Loper Bright, the U.S. Supreme Court greatly reduced judicial deference to regulatory agencies, which could increase successful legal challenges to federal regulations affecting our operations. Congress may introduce and ultimately pass health care related legislation that could impact the drug approval process and make changes to the Medicare Drug Price Negotiation Program.

At the state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, on January 5, 2024, the FDA approved Florida's Section 804 Importation Program (SIP) proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products covered by those programs.

Employees and Human Capital Resources

As of December 31, 2025, we had 76 full-time employees. All of our employees are located in the United States. None of our employees is represented by a labor union or covered by a collective bargaining agreement. We consider our relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and new employees, advisors and consultants. The principal purposes of our equity incentive plans are to attract, retain and reward personnel through the granting of stock-based compensation awards in order to increase stockholder value and the success of our company by motivating such individuals to perform to the best of their abilities and achieve our objectives.

Insurance

We currently maintain product liability insurance coverage for our products and clinical trials in amounts consistent with industry standards. However, insurance coverage is becoming increasingly expensive, and we may not be able to obtain or maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability.

Corporate Information

We were incorporated under the laws of the State of Delaware on July 3, 2013. Our principal executive offices are located at 44 West Gay Street, Suite 400, West Chester, PA 19380 and our telephone number is (484) 453-3300.

ITEM 1A. RISK FACTORS

You should carefully consider the risks described below, as well as general economic and business risks and the other information in this Annual Report on Form 10-K. The occurrence of any of the events or circumstances described below or other adverse events could have a material adverse effect on our business, results of operations and financial condition and could cause the trading price of our common stock to decline. Additional risks or uncertainties not presently known to us or that we currently deem immaterial may also harm our business.

Risk Factors Summary

Our business is subject to a number of risks and uncertainties, including those risks discussed below. These risks include, among others, the following:

Risks Related to Our Financial Position and Capital Needs

•We have incurred significant losses since our inception. We expect to incur losses until revenue from YCANTH (VP-102) for the treatment of molluscum is sufficient to fund our operations, if ever, and we may never achieve or maintain profitability.

•We will need substantial additional funding to meet our financial obligations and to pursue our business objectives, including the continued commercialization of YCANTH (VP-102) for the treatment of molluscum as well as the development of YCANTH (VP-102) for the treatment of common warts and VP-315 for the treatment of basal cell carcinoma. If we are unable to raise capital when needed, we could be forced to curtail our planned operations and the pursuit of our growth strategy, which could have a material adverse impact on our financial results and future operations.

•We have a limited operating history and limited history of commercializing products, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

•Greater than expected returns of YCANTH (VP-102) may exceed our reserve for returns, which would adversely affect our revenue and operating results.

•While our financial statements have been prepared assuming that we will continue as a going concern, we do not currently have sufficient working capital to fund our planned operations for the next twelve months and substantial doubt exists as to our ability to continue as a going concern.

Risks Related to the Development of Our Product Candidates

•If we are unable to successfully develop, receive regulatory approval for and commercialize any additional product candidates, or experience significant delays in doing so, our business will be harmed.

Risks Related to the Commercialization of Our Product and Other Product Candidates

•We face substantial competition which may result in a smaller than expected commercial opportunity and/or others discovering, developing or commercializing products before or more successfully than we do.

•The success of YCANTH (VP-102) for the treatment of molluscum and our product candidates will depend significantly on coverage and adequate reimbursement or the willingness of patients to pay for these procedures.

•The market for YCANTH (VP-102) for the treatment of molluscum and our product candidates may not be as large as we expect.

Risks Related to Our Dependence on Third Parties

•We currently rely on a third party to supply the raw materials and applicator components used for YCANTH (VP-102) and if we encounter any extended difficulties in procuring, or creating an alternative for those components or our raw material in YCANTH (VP 102) or any of our product candidates, our business operations would be impaired.

•We have entered into, and may seek additional, collaborations with third parties for the development or commercialization of our product candidates. If those collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates.

Risks Related to Our Intellectual Property

•If we are unable to obtain or protect intellectual property rights related to any of our product candidates, we may not be able to compete effectively in our market.

Risks Related to Ownership of Our Common Stock and Our Status as a Public Company

•The trading price of the shares of our common stock may be volatile, and purchasers of our common stock could incur substantial losses.

•If we fail to meet all applicable requirements of Nasdaq and Nasdaq determines to delist our common stock, the delisting could adversely affect the market liquidity of our common stock and the market price of our common stock could decrease.

.

Risks Related to Our Financial Position and Capital Needs

We have incurred significant losses since our inception. We expect to incur losses until revenue from YCANTH (VP-102) is sufficient to fund our operations, if ever, and may never achieve or maintain profitability.

We are a therapeutics company developing and commercializing medications for the treatment of dermatologic diseases, including skin cancers. Since inception, we have incurred significant net losses. We incurred net losses of $17.9 million and $76.6 million for the years ended December 31, 2025 and 2024, respectively. As of December 31, 2025, we had an accumulated deficit of $324.9 million. Since inception, we have financed our operations primarily through the sale of equity and equity-linked securities and through borrowings under loan agreements.

We have devoted substantially all of our financial resources and efforts to the development of our novel topical solution of cantharidin and our product, YCANTH (VP-102), for the treatment of molluscum, including preclinical studies and clinical trials. YCANTH (VP-102) was approved by the Food and Drug Administration, or FDA, for the treatment of molluscum in July 2023. We are also developing YCANTH (VP-102) as a treatment for common warts and VP-315 for the treatment of BCC and potentially additional dermatological oncology indications.

Therefore, we expect to continue to incur significant expenses and operating losses until revenue from YCANTH (VP-102) for the treatment of molluscum is sufficient to fund our operations. Our net losses may fluctuate significantly from quarter to quarter and year to year. Our expenses may increase as we:

•continue to establish our commercialization infrastructure and scale up external manufacturing and distribution capabilities to commercialize YCANTH (VP-102) for the treatment of molluscum and product candidates for which we may obtain regulatory approval;

•continue our ongoing clinical programs evaluating VP-102 for the treatment of common warts and VP-315 for the treatment of BCC and potentially additional dermatological oncology indications;

•pursue regulatory approvals for YCANTH (VP-102) for the treatment of common warts and VP-315 for the treatment of BCC;

•seek to in-license or acquire additional product candidates for other dermatological conditions;

•adapt our regulatory compliance efforts to incorporate requirements applicable to marketed products;

•maintain, expand and protect our intellectual property portfolio;

•hire and retain clinical, manufacturing, commercialization and scientific personnel; and

•incur additional legal, accounting and other expenses in operating as a public company.

To become and remain profitable, we must succeed in commercializing YCANTH (VP-102) for the treatment of molluscum and developing and eventually commercializing product candidates that generate significant revenue. This will require us to be successful in a range of challenging activities, including the continued commercialization of YCANTH (VP-102) for the treatment of molluscum, completing preclinical testing and clinical trials of our product candidates, obtaining regulatory approval, and manufacturing, marketing and selling any product candidates for which we may obtain regulatory approval, as well as discovering and developing additional product candidates. We are only in the preliminary stages of most of these activities. We may never succeed in these activities and, even if we do, may never generate revenue that is significant enough to achieve profitability.

27

Table of Contents

Our revenue will be dependent, in part, upon the size of the markets in the territories for which we have gained or may gain regulatory approval, the accepted price for the product, the ability to obtain coverage and reimbursement, and whether we own the commercial rights for that territory. If the number of our addressable patients is not as significant as we estimate, the indication approved by regulatory authorities is narrower than we expect, or the treatment population is narrowed by competition, physician choice or treatment guidelines, we may not generate significant revenue from sales of such products.

Because of the numerous risks and uncertainties associated with commercialization and product development, we are unable to accurately predict the timing or amount of expenses or when, or if, we will be able to achieve profitability. If we are required by regulatory authorities to perform studies in addition to those expected, or if there are any delays in the initiation and completion of our clinical trials or the development of any of our product candidates, our expenses could increase.

Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, maintain our development efforts, obtain product approvals, diversify our offerings or continue our operations.

We will need substantial additional funding to meet our financial obligations and to pursue our business objectives, including the continued commercialization of YCANTH (VP-102) for the treatment of molluscum as well as the development of YCANTH (VP-102) for the treatment of common warts and VP-315 for the treatment of BCC. If we are unable to raise capital when needed, we could be forced to curtail our planned operations and the pursuit of our growth strategy, which could impact our ability to continue as a going concern.

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory approval and achieve product sales of our product candidates. We expect to continue to incur significant expenses over the next several years as we commercialize YCANTH (VP-102) for the treatment of molluscum, pursue clinical trials and marketing approval for YCANTH (VP-102) for the treatment of common warts and potentially other indications, pursue clinical trials and marketing approval for VP-315 for the treatment of BCC and potentially additional dermatological oncology indications and advance any of our other product candidates we may develop or otherwise acquire. YCANTH (VP-102), for the treatment of molluscum and our product candidates, if approved, may not achieve commercial success. Although YCANTH (VP-102) has been approved by the FDA for the treatment of molluscum, we do not expect to generate substantial revenue from YCANTH (VP-102) in the near term. We have incurred, and expect to continue to incur, significant commercialization expenses related to product sales, marketing, distribution and manufacturing of YCANTH (VP-102) as well as any product candidates for which we receive marketing approval.

Based on our current business plan and current capital resources, consisting of cash and cash equivalents of $30.1 million as of December 31, 2025, combined with the uncertainty regarding the availability of additional funding, we have concluded that there is substantial doubt regarding our ability to continue as a going concern within one year after the date the accompanying financial statements are issued. This estimate is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. If we are unable to obtain sufficient funding, our business, prospects, financial condition and results of operations will be materially and adversely affected and we may be unable to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited financial statements, and it is likely that investors will lose all or a part of their investment. In addition, if there remains substantial doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding to us on commercially reasonable terms or at all.

Changes may occur beyond our control that would cause us to consume our available capital before that time, including changes in and progress of our commercialization activities for YCANTH (VP-102) for the treatment of molluscum, our development activities, acquisitions of additional product candidates, and changes in regulation. Our future capital requirements will depend on many factors, including:

•the progress and success of commercializing YCANTH (VP-102) for the treatment of molluscum in the United States;

28

Table of Contents

•the costs and timing of commercialization activities, including product manufacturing, marketing, sales and distribution, for YCANTH (VP-102) for the treatment of molluscum and any of our product candidates for which we may receive marketing approval;

•the scope, progress, costs and results of our development programs evaluating YCANTH (VP-102) as a potential treatment for common warts, as well as VP-315 for the treatment of BCC;

•the extent to which we develop, in-license or acquire product candidates or technologies;

•the number and development requirements of product candidates that we may pursue;

•the costs, timing and outcome of regulatory review of our product candidates;

•the revenue received from commercial sales of YCANTH (VP-102) for the treatment of molluscum and any of our product candidates for which we receive marketing approval;

•our ability to establish collaborations to commercialize YCANTH (VP-102) for the treatment of molluscum or any of our product candidates outside the United States; and

•the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims.

We will require additional capital to continue to commercialize YCANTH (VP-102) for the treatment of molluscum, and to develop YCANTH (VP-102) for the treatment of common warts, and VP-315 for the treatment of BCC and potentially other dermatological indications. If we receive regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize. Additional funds may not be available on a timely basis, on favorable terms, or at all, and such funds, if raised, may not be sufficient to enable us to continue to implement our long-term business strategy. If we are unable to raise sufficient additional capital, we could be forced to curtail our planned operations and the pursuit of our growth strategy. For example, we have paused the development of VP-102 for the treatment of external genital warts and VP-103 for the treatment of plantar warts due to our cash position.

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate substantial revenue, we may finance our cash needs through a combination of equity offerings, debt financings and license and collaboration agreements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

SEC regulations limit the amount of funds we can raise during any 12-month period pursuant to our shelf registration statement on Form S-3.

SEC regulations limit the amount that companies with a public float of less than $75 million may raise during any 12-month period pursuant to a shelf registration statement on Form S-3, referred to as the baby shelf rules. As of the filing of this Annual Report on Form 10-K, we are subject to such rules. Under these rules, the amount of funds we can raise through primary public offerings of securities in any 12-month period using our registration statement on Form S-3, including our at-the-market equity offering program, will be limited to one-third of the aggregate market value of the shares of our common stock held by our non-affiliates. Therefore, we will be significantly limited in the amount of proceeds we are able to raise by selling shares of our common stock using our Form S-3 until such time as our public float exceeds $75 million. Furthermore, if we are required to file a new registration statement on another form, we may incur additional costs and be subject to delays due to review by the SEC staff.

We have a limited operating history and limited history of commercialization, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

Our operations to date have been largely focused on raising capital and developing YCANTH (VP-102) for the treatment of molluscum and our product candidates, including undertaking preclinical studies and conducting clinical trials. YCANTH (VP-102), which was approved by the FDA for treatment of molluscum in July 2023, is our only approved product and became commercially available in August 2023. We have not yet demonstrated our ability to successfully manufacture a product on a commercial scale, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful commercialization over an extended timeframe. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully commercializing products.

While our financial statements have been prepared assuming that we will continue as a going concern, we do not currently have sufficient working capital to fund our planned operations for the next twelve months and substantial doubt exists as to our ability to continue as a going concern.

While our financial statements have been prepared assuming that we will continue as a going concern, we do not currently have sufficient working capital to fund our planned operations for the next twelve months and substantial doubt exists as to our ability to continue as a going concern. Based on our current business plan and current capital resources, consisting of cash and cash equivalents of $30.1 million as of December 31, 2025, combined with the uncertainty regarding the availability of additional funding, we have concluded that there is substantial doubt regarding our ability to continue as a going concern within one year after the date the accompanying financial statements are issued.

Until we can generate sufficient revenue to fund our operations, we will need to finance future cash needs through public or private equity offerings, license agreements, debt financings or restructurings, collaborations, strategic alliances and marketing or distribution arrangements. The perception of our ability to continue as a going concern may make it more difficult for us to obtain financing for the continuation of our operations and could result in the loss of confidence by investors and employees. If we are unable to obtain sufficient funding, our business, prospects, financial condition and results of operations will be materially and adversely affected, and we may be unable to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our financial statements, and it is likely that investors will lose all or a part of their investment.

Risks Related to the Development of Our Product Candidates

If we are unable to successfully develop, receive regulatory approval for and commercialize any product candidates, or experience significant delays in doing so, our business will be harmed.

We currently have only one product that is approved for commercial sale. We have invested substantially all of our efforts and financial resources in the development of YCANTH (VP-102) for the treatment of molluscum. We are also developing YCANTH (VP-102) as a treatment for common warts, and VP-315 for the treatment of BCC and potentially additional dermatological oncology indications. Our ability to generate substantial revenue from YCANTH (VP-102) for the treatment of molluscum or our product candidates will depend heavily on their successful development, regulatory approval and commercialization. The success of YCANTH (VP-102) for the treatment of molluscum and any product candidates that we develop or otherwise may acquire which receive regulatory approval will depend on several factors, including:

•timely and successful completion of preclinical studies and our clinical trials;

•successful development of, or making arrangements with third-party manufacturers for, our commercial manufacturing processes for YCANTH (VP-102) and any of our product candidates that receive regulatory approval;

•receipt of timely marketing approvals from applicable regulatory authorities;

•commercial sales of YCANTH (VP-102) for the treatment of molluscum and, if approved, our product candidates

•acceptance of YCANTH (VP-102) for the treatment of molluscum and, if approved, our product candidates, by patients, the medical community and third-party payors, for their approved indications;

•our success in educating physicians and patients about the benefits, administration and use of YCANTH (VP-102) for the treatment of molluscum and, if approved, our product candidates;

30

Table of Contents

•the prevalence and severity of adverse events experienced with YCANTH (VP-102) for the treatment of molluscum and our product candidates;

•the availability, perceived advantages, cost, safety and efficacy of alternative treatments for the indications addressed by our product and product candidates;

•our ability to produce YCANTH (VP-102) for the treatment of molluscum and, if approved, our product candidates on a commercial scale;

•obtaining and maintaining patent, trademark and trade secret protection and regulatory exclusivity for our product and product candidates and otherwise protecting our rights in our intellectual property portfolio;

•maintaining compliance with regulatory requirements, including current good manufacturing practices, or cGMPs;

•competing effectively with other procedures; and

•maintaining a continued acceptable safety, tolerability and efficacy profile of the products following approval.

Whether regulatory approval will be granted is unpredictable and depends upon numerous factors, including the substantial discretion of the regulatory authorities. Our product candidates' success in clinical trials is not guaranteed, and even if clinical trials are successful, it will not guarantee regulatory approval. Following submission of an NDA, it may not be accepted for substantive review, or even if it is accepted for substantive review, the FDA or other comparable foreign regulatory authorities may require that we conduct additional studies or clinical trials, provide additional data, take additional manufacturing steps, or require other conditions before they will reconsider or approve our application. If the FDA or other comparable foreign regulatory authorities require additional studies, clinical trials or data, we would incur increased costs and delays in the marketing approval process, which may require us to expend more resources than we have available. In addition, the FDA or other comparable foreign regulatory authorities may not consider sufficient any additional required studies, clinical trials, data or information that we perform and complete or generate, or we may decide to abandon the program.

It is possible that our product candidates will never obtain regulatory approval, even if we expend substantial time and resources seeking such approval. If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our product candidates, which would harm our business.

Clinical product development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

The risk of failure for product candidates is high. It is impossible to predict when or if any of our product candidates will prove effective or safe in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is inherently uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing or at any time during the trial process. The outcome of preclinical testing and early clinical trials may not be predictive of the results of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products.

We cannot assure you that any clinical trial that we have conducted, are currently conducting, or may conduct in the future will demonstrate consistent or adequate efficacy and safety to obtain regulatory approval to market our product candidates.

We may experience delays in ongoing clinical trials for our product candidates, and we do not know whether future clinical trials, if any, will begin on time, need to be redesigned, enroll an adequate number of patients on time or be

31

Table of Contents

completed on schedule, if at all. We may experience numerous unforeseen events during or as a result of clinical trials that could delay or prevent our ability to receive marketing approval or commercialize our product candidates, including:

•regulators or institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;

•we may experience delays in reaching, or failing to reach, agreement on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites or prospective contract research organizations, or CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

•clinical trials of our product candidates may produce negative or inconclusive results, including failure to demonstrate statistical significance, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon product development programs;

•the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate, or participants may drop out of these clinical trials or fail to return for post-treatment follow-up at a higher rate than we anticipate;

•our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators or institutional review boards to suspend or terminate the trials;

•our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;

•regulators or institutional review boards may require that we or our investigators suspend or terminate clinical development for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks;

•the cost of clinical trials of our product candidates may be greater than we anticipate; and

•the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient or inadequate.

We could also encounter delays if a clinical trial is suspended or terminated by us, by the institutional review boards of the institutions in which such trials are being conducted, by the safety review committee for such trial or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. If we are required to conduct additional clinical trials or other testing of our product candidates beyond those we currently contemplate, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not favorable or if there are safety concerns, we may:

•be delayed in obtaining marketing approval for our product candidates;

•not obtain marketing approval at all;
