PART I

ITEM 1 - BUSINESS

Overview

We are a clinical-stage biopharmaceutical company focused on developing proprietary, innovative and differentiated therapies for the treatment of immuno-inflammatory conditions.

In August 2021, we entered into a transaction with Tay Therapeutics Ltd. (formerly known as In4Derm Ltd., "Tay") providing us with exclusive worldwide rights to research, develop and commercialize products containing bromodomain and extra-terminal (“BET”) inhibitors for the treatment of any disease, disorder or condition in humans. Through our access to this library of new chemical BET inhibitor compounds, we plan to develop product candidates for a diverse set of indications. Based on preclinical data generated to date, we have chosen to focus our initial efforts for this platform on select therapeutic areas in immuno-inflammatory disease.

Our lead program is VYN201, a locally administered pan-BET inhibitor designed as a “soft” drug to address diseases involving multiple, diverse inflammatory cell signaling pathways while providing low systemic exposure. To date, VYN201 has produced consistent reductions in pro-inflammatory and disease-related biomarkers, improvements in disease severity and a demonstrated local activity through several preclinical models. We believe that these data suggest potential broad utility for VYN201 across multiple routes of administration. In November 2022, we initiated a Phase 1a/b clinical trial evaluating a topical formulation of VYN201 for the treatment of nonsegmental vitiligo. In February 2023, we announced positive preliminary safety data from the Phase 1a portion of the trial. The first nonsegmental vitiligo patient was dosed in the Phase 1b portion of the trial in January 2023 and we expect topline results from this trial in mid-2023.

Our second program is VYN202, a BD2-selective oral small molecule BET inhibitor. VYN202 is in preclinical development for the treatment of immuno-inflammatory indications, and is being designed to achieve class-leading selectivity (BD2 vs. BD1), maximum potency versus BD2 and optimal oral bioavailability. By maximizing BD2 selectivity, we believe VYN202 has the potential to be a more conveniently-administered non-biologic treatment option for both acute control and chronic management of immuno-inflammatory indications, where the damaging effects of unrestricted inflammatory signaling activity is common.

We intend to actively evaluate and enter into strategic partnerships to advance our product candidates through the clinic toward commercialization, and may also partner with leading pharmaceutical companies to advance our molecules in therapeutic areas outside of our core focus in immunology. We believe selectively entering into collaborations has the potential to expand and accelerate the development of our programs and maximize the value of our pipeline.

BET Inhibition and Immuno-Inflammatory Disease

BET proteins are epigenetic enablers of transcription and regulate the expression of specific genes. Each BET protein consists of two bromodomains (BD1 and BD2) and one end terminal domain. BD1 and BD2 enable chromatin remodeling and recruit transcription factors to facilitate gene transcriptions. In certain cases, BET proteins activate oncogenes leading to increased cell proliferation and survival and an increase in solid tumors and hematologic malignancies. BET inhibitors have the potential to downregulate the expression of such oncogenes. These observations have resulted in the generation and clinical investigation of BET inhibitors in several cancer subtypes by pharmaceutical companies, including large pharmaceutical companies. In addition to impacting oncogenetics, BET proteins regulate the expression of many immunity-associated genes and pathways by directing the transcription of a wide range of pro-inflammatory and immunoregulatory genes, leading to increased cytokine expression that activate B cells and T cells and subsequent inflammatory processes. Inhibiting BET proteins prevents the formation of complexes required to facilitate transcription, thereby inhibiting the subsequent translation of the corresponding protein. As such, BET inhibitors could present as an attractive, non-steroidal, therapeutic option for the treatment of immuno-inflammatory diseases.

Our Portfolio of Product Candidates

InhiBET BET Inhibitor Platform

Through our partnership with Tay, we have exclusive worldwide rights to research, develop and commercialize products containing certain BET inhibitor compounds for the treatment of any disease, disorder or condition in humans. See "—Development and License Agreements—Tay License Agreements." Utilizing our InhiBET platform and through our preclinical and clinical activities, we are evaluating the impact that BET inhibitor compounds have on regulating pro-inflammatory cytokines. Based on this evaluation, we are targeting indications whose pathogenesis is linked to the proliferation of these specific cytokines, and we are developing formulations designed to maximize the anti-inflammatory effect of the drug while minimizing safety concerns. Through our InhiBET development platform, we believe we can demonstrate the potential utility of these BET inhibitor compounds and develop therapies for a variety of immuno-inflammatory conditions.

VYN201 - Locally Administered Pan-BD BET Inhibitor

Our lead BET inhibitor candidate in development is VYN201. VYN201 was developed using the InhiBET platform and is a locally administered pan-BD BET inhibitor. It is a first-in-class “soft” pan-BD BET inhibitor that is being developed to address diseases involving multiple, diverse inflammatory cell signaling pathways. Our goal with the VYN201 program is to develop a therapy that delivers a potent, localized anti-inflammatory effect and is rapidly cleared through metabolic processes so as to avoid systemic absorption.

To date, we have conducted several preclinical studies which have demonstrated VYN201's anti-fibrotic and anti-inflammatory activity and the ability to significantly reduce the expression of certain cytokines relevant to certain autoimmune diseases. Based on such data, we believe VYN201 has the potential to be highly versatile by serving as a locally acting therapy with low systemic exposure.

Phase 1a/b Clinical Trial in Nonsegmental Vitiligo

Vitiligo is a chronic autoimmune depigmenting disorder of the skin, characterized by the loss of pigment producing cells known as melanocytes. Vitiligo is the most common depigmenting skin condition, with a prevalence estimated at 0.5-2% of the world population. It is estimated that there are at least 1.9 million patients diagnosed with vitiligo in the United States, with the majority of patients (approximately 90%) suffering from nonsegmental vitiligo. There is currently only one FDA-approved product for the treatment of nonsegmental vitiligo which includes a black box safety warning. Based on preclinical data generated to date, we believe that VYN201 has the potential to offer a targeted, safe and more efficacious treatment option that lowers the disease recurrence rate and is effective for all skin tones and scar types.

In November 2022, we announced the commencement of a Phase 1a/b clinical trial evaluating VYN201 for the treatment of nonsegmental vitiligo. The Phase 1a/b clinical trial is being conducted in U.S.-based clinical centers. In the Phase 1a portion of the clinical trial, single ascending and multiple ascending doses of VYN201 were applied topically once daily to 30 healthy volunteers in five dose cohorts for two weeks with a one-week safety follow-up visit to evaluate the safety, tolerability and pharmacokinetics of VYN201. Evaluated doses included VYN201 0.025%, 0.1%, 0.5%, 1.0% and 2.0% ointment strengths. There were no serious adverse events and no dose adjustments were required. There were no clinically relevant treatment

emergent adverse events, abnormal clinical laboratory results or electrocardiogram findings. No healthy volunteers withdrew from the trial for any reason. Based on these results, we selected 0.5%, 1.0% and 2.0% ointment strengths for evaluation in the ongoing Phase 1b trial evaluating VYN201 in nonsegmental vitiligo patients.

In January 2023, we dosed the first vitiligo patient in the Phase 1b portion of the Phase 1 trial. In the Phase 1b portion, up to 30 patients with a clinical diagnosis of nonsegmental vitiligo will receive VYN201 once daily for up to 16 weeks in three dose cohorts. Exploratory efficacy of VYN201 in nonsegmental vitiligo patients will be assessed, including pharmacodynamic biomarkers and photography. We expect topline results for the Phase 1b portion of the trial in mid-2023.

Vitiligo Preclinical Model

In March 2022, we announced positive preclinical data in an ex vivo skin model of vitiligo.The objectives of this study were to evaluate the potential of VYN201 to (i) reduce Matrix Metalloproteinase-9 (“MMP-9”) secretion (reducing the secretion of MMP-9 allows for melanocyte stabilization and limits loss of melanocytes/depigmentation in vitiligo); (ii) reduce soluble adhesion molecule, E-cadherin (soluble E-cadherin is a biomarker of melanocyte loss due to degradation of matrix-bound E-cadherin by MMP-9); (iii) minimize the loss of melanocytes by assessing melanin pigment content and (iv) affect the expression of genes commonly associated with melanogenesis (melanin synthesis, melanosome maturation and transport). In the preclinical model, VYN201 reduced the expression of key pro-inflammatory biomarkers relevant to the pathogenesis of vitiligo, and demonstrated marked reduction in melanocyte loss. Specifically, VYN201 produced a dose dependent reduction in MMP-9 and soluble E-cadherin and substantially reduced the loss of melanin pigment in the basal layers of skin at the 0.1% and 1% concentrations. In addition, VYN201 significantly upregulated WNT16, a member of the WNT family of genes. The WNT signaling pathway is known to be dysregulated in vitiligo and is believed to play a key role in melanocyte regeneration.

Th17 Inflammation Preclinical Model

Data suggests that T helper 17 (Th17) cells play an important role in the pathogenesis of a diverse group of immune-mediated diseases, including psoriasis, rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease, and asthma, among others. In October 2021, we evaluated the impact of VYN201 on Th17 mediated inflammation in a well-established preclinical animal model and an ex vivo human tissue study. In the animal model, depilated mice were topically dosed with imiquimod cream to induce a Th17 inflammation pathology over a 7-day induction phase. A further 7-day treatment phase evaluated three doses of VYN201 (0.001%, 0.01% and 0.1% concentrations) compared to a class 1 super-potent glucocorticosteroid product positive control (clobetasol propionate 0.05% cream) and vehicle control. Further, an imiquimod-naive control group (healthy control group) was included for VYN201 vehicle treatment. VYN201 significantly reduced the expression of several key pro-inflammatory cytokines relevant to Th17-mediated autoimmune diseases in the animal model and the ex vivo human tissue study. A dose-dependent improvement in the signs and symptoms of inflammation was observed for VYN201 treatment groups and treatment with VYN201 at all concentrations was well-tolerated.

Fibrotic Tissue Preclinical Model

In November 2021, we announced results from a preclinical animal model in which we evaluated VYN201's ability to reduce fibrosis. In the preclinical study, duplicate identical skin incisions were induced on the flanks of hairless mice under anesthesia. The animals were topically dosed once daily with either 100mg VYN201 vehicle, VYN201 1%, or a hydroalcoholic gel (a negative control known to delay healing) until each lesion had completely healed. VYN201 demonstrated improvements in reducing fibrotic tissue mass and overall skin repair outcomes with no negative impact on healing time. Animals treated with VYN201 1% had a statistically significant decrease (improvement) in global external lesion severity score, a comprehensive evaluation of length, width, swelling and visibility of lesions, compared to those treated with hydroalcoholic gel, consistent with the vehicle control. In addition, animals treated with VYN201 1% had a significantly lower global internal lesion severity score than those treated with VYN201 vehicle or hydroalcoholic gel, indicative of an improved internal lesion outcome and a positive effect on reducing the formation of fibrotic tissue mass in the lesion bed.

Rheumatoid Arthritis Preclinical Model

In March 2022, we announced preclinical data showing that intra-articular injections of VYN201 resulted in significant inhibition of inflammation in a validated animal model of rheumatoid arthritis. In the preclinical study, inflammatory arthritis was induced in BALB/c mice by systemically injecting a mixture of four arthritogenic monoclonal antibodies against collagen II at day 1. In addition, the mice received a lipopolysaccharide injection systemically at day 4 to stimulate an acute systemic inflammatory response. Each treatment group (n=7 per group) was injected with either (i) an intra-articular dose of VYN201 vehicle, (ii) an intra-articular dose of VYN201, (iii) an intra-articular dose of dexamethasone (1 mg/kg) or (iv) a systemic dose of dexamethasone (1 mg/kg, via intraperitoneal injection). The intra-articular doses were administered on days 0, 3, 6 and 9 while the dexamethasone systemic injections were given daily beginning at day 0 through 11. For the VYN201 treatment groups, four doses of VYN201 were evaluated (at concentrations ranging from 0.01 to 10 mg/kg). Each animal treated with the

8

Table of Contents

intra-articular injections received the injection in the ankle of one rear paw. The untreated rear paw was assessed to evaluate any potential anti-inflammatory systemic effect. Treatment response was evaluated based on an assessment of paw thickening or swelling (in millimeters) and arthritis scoring based on a five-point composite severity scale of redness, swelling of the ankles and wrists, and paw thickness. Scoring in this model ranges from 0 (normal) to 4 (extensive signs and symptoms of arthritis). VYN201 demonstrated marked inhibition of paw thickening at the 1 and 10 mg/kg doses. At both doses, the inhibition of paw thickening was statistically significant in the treated paw relative to the untreated rear paw on day 12 (p<0.01). In addition, limbs treated with VYN201 at the 1 and 10 mg/kg dose levels had an average arthritis score of 0.57 and 0.67, respectively, or near normal. The arthritis score was significantly lower in the treated paw at both doses relative to the non-treated paws on day 12 (p<0.05).

VYN202 - Selective BET Inhibitor

We are currently evaluating several BD2-selective oral small molecule BET inhibitors for our VYN202 program. Systemic BET inhibitors have historically targeted both BD1 and BD2 less selectively, causing gastrointestinal and hematologic toxicities, such as thrombocytopenia. The compounds that we are currently evaluating for our VYN202 program are being designed to potentially reduce the therapeutic limiting toxicities of BRD4 BET inhibitors currently in development by optimizing BD2 versus BD1 selectivity. By maximizing BD2 selectivity, we believe VYN202 has the potential to present a more conveniently-administered non-biologic treatment option for both acute control and chronic management of immuno-inflammatory indications, where the damaging effects of unrestricted inflammatory signaling activity is common. Following the receipt of positive results from our preclinical activities evaluating these compounds, we intend to exercise our option with respect to the oral molecules. See "—Development and License Agreements—Agreements with Tay Therapeutics" for additional information.

FMX114

FMX114 is our proprietary investigational combination gel formulation of tofacitinib and fingolimod that is designed to address both the source and cause of inflammation in atopic dermatitis ("AD"). On August 10, 2022, we announced that our Phase 2a clinical trial evaluating the safety and efficacy of FMX114 for mild-to-moderate AD did not meet its primary endpoint, which was based on assessments of the absolute and percent change relative to baseline in the atopic dermatitis severity index (“ADSI”) scoring assessment at week 4. In the weeks that followed, we performed additional analyses which showed that while efficacy results for FMX114 were not statistically significant at week 4, FMX114 was statistically superior to vehicle at weeks 1, 2 and 3 in the Phase 2a trial. Additionally, data received from the two-week open label extension during which both AD lesions of participating patients were treated with FMX114 showed that efficacy results continued to develop beyond week 4 of the trial and that the separation of treatment effect for lesions treated with FMX114 as compared to lesions treated with vehicle increased for lesions that had a higher ADSI score at baseline. Accordingly, we believe that FMX114 may have an improved overall treatment effect on patients with more severe disease at baseline and that FMX114 may have increased potential to effectively treat patients with more moderate-to-severe AD. We are evaluating partnering opportunities for this program and intend to focus our resources on the BET inhibitor development programs.

Divestiture of Minocycline Business

On January 12, 2022, we entered into an Asset Purchase Agreement (the “Purchase Agreement”) with Journey Medical Corporation (“Journey”) pursuant to which we divested our Molecule Stabilizing Technology franchise ("MST Franchise"), including AMZEEQ, ZILXI, and FCD105, to Journey (the “Sale”). Pursuant to the Purchase Agreement, we received an upfront payment of $20.0 million and an additional $5.0 million on January 12, 2023, the one-year anniversary of the closing of the transaction. We are also eligible to receive sales milestone payments of up to $450.0 million in the aggregate upon the achievement of specified levels of net sales on a product-by-product basis, beginning with annual net sales exceeding $100,000,000 (with products covered in three categories (1) AMZEEQ (and certain modifications), (2) ZILXI (and certain modifications), and (3) FCD105 and other products covered by the patents being transferred, including certain modifications). In addition, we are entitled to receive certain payments from any licensing or sublicensing of the assets by Journey outside of the United States. The Purchase Agreement includes customary representations and warranties, as well as indemnification rights for breaches of representations, warranties, and covenants, as well as certain other matters, subject to customary deductibles, caps, and other limitations.

Manufacturing

We currently contract with third party manufacturers for all of our required raw materials, active ingredients and finished products for our preclinical research and clinical trials for our product candidates. We currently have no plans to establish our own manufacturing capabilities and plan to continue to rely on third-party manufacturers for any future trials of our product candidates.

We, together with our contract manufacturing organizations ("CMOs") have developed the validation processes, methods, tests and/or controls suitable for the manufacturing of our product candidates and for defining their properties. Development stage quantities of any products that we develop need to be manufactured in facilities, and by processes, that comply with the requirements of the FDA and the regulatory agencies of other jurisdictions in which we may seek approval. We require all of our CMOs to comply with these requirements and currently employ internal and external resources to manage our manufacturing contractors. The relevant manufacturers of our product candidates for our current preclinical and clinical trials have advised us that they are compliant with both the FDA’s Good Laboratory Practices ("GLP") and cGMP.

Development and License Agreements

Agreements with Tay Therapeutics

On April 30, 2021, we entered into an Evaluation and Option Agreement (the “Option Agreement”) with Tay. Tay is a spin-out of the University of Dundee’s School of Life Sciences and has discovered and is developing proprietary BET inhibitors for the treatment of immunology and oncology conditions. Pursuant to the Option Agreement, Tay granted us an exclusive option to obtain certain exclusive worldwide rights to research, develop and commercialize products containing Tay’s BET inhibitor compounds for the treatment of any disease, disorder or condition in humans. Pursuant to the Option Agreement, we agreed to use commercially reasonable efforts to stabilize, develop and manufacture a product with a pan-BD BET inhibitor as its active ingredient and Tay agreed to provide a mutually agreed data package and select an NCE development candidate from its highly selective BET inhibitor compounds (the "Oral BETi Compounds"). We paid a $1.0 million non-refundable cash payment to Tay upon execution of the Option Agreement, 50% of which was to be used by Tay in the development of the Oral BETi Compounds.

Locally Administered Pan-BD BET Inhibitor Program (VYN201)

On August 6, 2021, we exercised our option with respect to the VYN201 program and, on August 9, 2021, the parties entered into a License Agreement (the “VYN201 License Agreement”) granting VYNE a worldwide, exclusive license that is sublicensable through multiple tiers to exploit certain of Tay’s pan-BD BET inhibitor compounds. We have the sole responsibility for development, regulatory, marketing and commercialization activities to be conducted for the licensed products at our sole cost and discretion. We are required to use commercially reasonable efforts to develop and, if approved, commercialize such products. Pursuant to the VYN201 License Agreement, a joint development committee consisting of one representative from each party reviews the progress of the development plan for the licensed products. Pursuant to the VYN201 License Agreement, we may develop a product that contains or incorporates a specific BET inhibitor, whether alone or in combination with other active ingredients, in any form, formulation, presentation, or dosage, and for any mode of administration.

We made a $0.5 million cash payment to Tay in connection with entering into the VYN201 License Agreement. Pursuant to the VYN201 License Agreement, we have agreed to make cash payments to Tay upon the achievement of specified clinical development and regulatory approval milestones with respect to each licensed topical product in the United States of up to $15.75 million for all indications.

Under the original terms of the Option Agreement, the Option was to expire upon the earlier of (i) 14 days following the delivery of an agreed data package and selection of a lead candidate by In4Derm and (ii) June 30, 2022 (the “Option Term”). On June 15, 2022, the parties entered into a letter agreement to extend the Option Term to February 28, 2023. We recently informed Tay that we require additional preclinical data in order to complete our assessment of the Oral BETi Compounds. In consideration of the significant progress made by the parties and our desire to maintain optionality with respect to our right to exercise the Option for the Oral BETi Compounds, the parties entered into a Letter Agreement on February 27, 2023 (the “Letter Agreement”) to extend the Option Term to April 30, 2023. Pursuant to the terms of the Letter Agreement, we agreed to pay Tay a non-refundable fee in the

amount of $250,000 to extend the Option Term. This fee will be deducted from the $4.0 million payable to Tay in the event that we exercise the Option pursuant to the Option Agreement.

In the event that we exercise the Option, the parties will sign a license agreement (the “Oral License Agreement”) and we will pay Tay a $4.0 million upfront cash payment, less the amount paid pursuant to the Letter Agreement. The Oral License Agreement will include cash payments of up to $43.75 million payable to Tay upon the achievement of specified clinical development and regulatory approval milestones with respect to each licensed oral product in the United States for all indications. Tay will be entitled to additional milestones upon the achievement of regulatory approvals in certain jurisdictions outside the U.S. In addition, with respect to any products we commercialize under the Oral License Agreement, we will pay tiered royalties to Tay on net sales of such licensed products by us, our affiliates, or sublicensees, of 5%, 7.5% and 10% based on tiered annual net sales bands subject to specified reductions.

LEO Pharma A/S for Finacea® Foam

In September 2015, Bayer HealthCare AG ("Bayer") began selling in the United States a product branded Finacea® Foam, based on our legacy foam technology. Finacea is a prescription topical drug which was developed through a collaboration between Foamix (our predecessor) and Bayer. Bayer sold the product to LEO Pharma A/S ("LEO") in 2018. Pursuant to the license agreement with LEO for Finacea, we are entitled to receive royalties on net sales of Finacea. In 2022, we received (or became entitled to receive) a total of $0.5 million in royalties from sales of Finacea from LEO.

Intellectual Property

Our intellectual property and proprietary technology are essential to the development of our product candidates. We are committed to protecting our intellectual property rights, core technologies and other know-how through a combination of patents, trademarks, domain names, trade dress, trade secrets, copyrights, non-disclosure and confidentiality agreements, common interest agreements to protect privileged confidential information, licenses, assignments of invention and other contractual arrangements with our employees, scientific advisors, consultants, partners, suppliers, customers and others. Such agreements and rights may however be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets and other proprietary and confidential information may otherwise become known or be independently discovered by competitors. To the extent that our employees, scientific advisors, consultants, partners, or other contractors 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.

Our success will also depend at least in part on not infringing the proprietary rights of third parties. While we are diligent in our efforts to investigate proprietary rights of third parties, no search is completely exhaustive. For example, a relevant patent or published application could escape detection because of unusual terminology or use of terminology that is still evolving in developing technological fields. Also, databases used in the searches may not be entirely complete. It is uncertain whether the issuance of any third party patent would require us to alter our development strategies, alter our processes, obtain licenses or cease certain activities. Our breach of any license agreements or failure to obtain a license to proprietary rights that we may require to develop our current and future product candidates may have a material adverse impact on us. If third parties prepare and file patent applications in the United States that also claim technology to which we have rights, we may have to participate in derivation, interference or other proceedings in the United States Patent and Trademark Office ("USPTO") to determine derivation or priority of invention. We may also have to participate in court proceedings or arbitration to defend and assert our rights. See "Item 1A. Risk Factors—Risks Related to Our Intellectual Property."

Our patent portfolio in relation to our VYN201 BET inhibitor program includes a granted patent in the UK and pending compound and composition patent applications in various jurisdictions worldwide that are licensed by us. In addition, we have filed a PCT application directed to various uses thereof. We have various non-provisional and nationally filed PCT patent applications pending in relation to FMX114 including applications filed in Australia, Brazil, Canada, Europe, Japan and the US. Subject to filing a non-provisional, the PCT's being filed nationally, and the pending patent applications being granted (without terminal disclaimers) and payments of the appropriate maintenance fees, the patent applications in relation to VYN201 will expire in 2040 and 2042 and the patent applications related to FMX114 will expire in 2040, 2041 and 2043.

In addition, in connection with our legacy business, we have various granted patents worldwide owned or licensed by us related to pharmaceutical compositions and their uses, including various foam-based platforms, various gel-based platforms, and other technology.

Patents extend for varying periods according to the date of patent filing or grant and the legal term of patents in various countries where patent protection is obtained. The actual protection afforded by a patent, which can vary from country to

11

Table of Contents

country, depends on the type of patent, the scope of its coverage and the availability of legal remedies in the country. In most countries in which we file, the patent term is 20 years from the earliest date of filing a non-provisional patent application. In the United States, a patent term may be shortened if a patent is terminally disclaimed over another patent or as a result of delays in patent prosecution by the patentee, and a patent’s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the USPTO in granting a patent or by patent term extension, which compensates a patentee for delays at the FDA. The patent term of a European patent is 20 years from its filing date; however, unlike in the United States, the European patent does not grant patent term adjustments. The European Union does have a compensation program similar to patent term extension called supplementary patent certificate that would effectively extend the duration of protection of the product for up to five years. Obtaining a patent term extension in the US or a supplementary patent certificate in the European Union is uncertain and will depend on eligibility and satisfying rigorous criteria in each jurisdiction.

Competition

Our drug development activities face, and will continue to face, intense competition from organizations such as pharmaceutical and biotechnology companies, as well as academic and research institutions and government agencies. Our drug development activities also face, and may continue to face, governmental actions designed to promote generic drug competition and lower prices. Any product candidate that we successfully develop and commercialize will compete with existing treatments, including those that may have achieved broad market acceptance, and any new treatment that may become available in the future.

Many of the companies against which we are competing, or against which we may compete in the future, have significantly greater financial resources and expertise in research and development, manufacturing, and preclinical and clinical development than we do. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and subject registration for clinical trials, as well as in acquiring technologies complementary to, or that may be necessary for, our development programs.

For vitiligo, our primary competitors include topical therapies such as generic and branded versions of calcineurin inhibitors, including Elidel, marketed by Bausch Health; Opzelura, marketed by Incyte Corporation; branded and generic versions of high potency steroids, including Clobex, marketed by Galderma Laboratories, LP; and other treatments including various lasers and ultraviolet light-based therapies. In addition, there are several prescription product candidates under development that could potentially be used to treat vitiligo and compete with VYN201, including but not limited to: topical cerdulatinib, under development by Dermavant Sciences, Inc., and both oral PF-06651600 and oral PF-06700841 under development by Pfizer Inc.

While we have not yet identified an initial indication for VYN202, there is intense competition for the treatment of immuno-inflammatory conditions. VYN202, if approved, will compete with existing treatments and new treatments that may become available in the future.

The commercial opportunity for our product candidates, if approved, could be reduced or eliminated if our competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any drug we may develop. Our competitors also may obtain FDA or other regulatory approval for their product candidates more rapidly than us, which could result in our competitors establishing a strong market position before our product candidates are able to enter the market.

Government Regulation

Our business is subject to extensive government regulation. Regulation by governmental authorities in the United States and other jurisdictions is a significant factor in our research and development activities.

Product approval process in the United States

Review and approval of drugs

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act ("FDCA") and implementing regulations. In general, new drug products require the submission of a NDA and approval thereof by the FDA prior to being marketed in the United States. 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 U.S. requirements at any time during the product development process, approval process or after approval may subject an applicant to a variety of administrative or judicial sanctions and enforcement actions brought by the FDA, the Department of Justice or other governmental entities. Possible sanctions may include the FDA’s refusal to

12

Table of Contents

approve pending NDAs, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement and civil or criminal penalties.

The process required by the FDA prior to marketing and distributing a new drug product in the United States generally involves the following:

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

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

•approval by an independent institutional review board ("IRB") at each clinical site before each trial may be initiated at that site;

•performance of adequate and well-controlled human clinical trials in accordance with Good Clinical Practice ("GCP") requirements to establish the safety and efficacy of the proposed drug for its intended use;

•preparation and submission to the FDA of a NDA or supplemental NDA;

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

•satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the product or components thereof are produced, to assess compliance with cGMP and to assure that the facilities, methods and controls are adequate to preserve the drug’s identity, strength, quality and purity;

•satisfactory completion of FDA audits of clinical trial sites and the sponsor’s clinical trial records to assure compliance with GCPs and the integrity of the clinical data;

•payment of user fees and FDA review and approval of the NDA; and

•compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and Mitigation Strategy ("REMS") and the potential requirement to conduct post-approval studies.

Preclinical studies

Preclinical studies include laboratory evaluation, as well as animal studies to assess the potential safety and efficacy of the product candidate. Preclinical safety tests must be conducted in compliance with the FDA’s GLP regulations. The results of the preclinical tests, together with manufacturing information and analytical data, are submitted to the FDA as part of an IND which must become effective before clinical trials may be commenced.

Clinical trials in support of an NDA

Clinical trials involve the administration of an investigational product to human subjects under the supervision of qualified investigators in accordance with GCP requirements, which include, among other things, the requirement that all research subjects provide their informed consent in writing before their participation in any clinical trial. Clinical trials are conducted under written trial 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. An IND becomes effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to a proposed clinical trial and places the trial on clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin.

In addition, an IRB representing each institution participating in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution, and the IRB must conduct continuing review and reapprove the trial at least annually. The IRB must review and approve, among other things, the trial protocol and informed consent information to be provided to trial subjects. An IRB must operate in compliance with FDA regulations. Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health for public dissemination on their ClinicalTrials.gov website.

13

Table of Contents

Clinical trials are typically conducted in three sequential phases, which, in some cases, may overlap or be combined:

•Phase I: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 early indication of its effectiveness and to determine optimal dosage.

•Phase II: The drug is administered to a limited patient population to identify possible short-term 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.

•Phase III: 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 efficacy and safety 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.

Submission of a NDA to the FDA

The results of the preclinical studies and clinical trials, together with other detailed information, including information on the manufacture, control and composition of the product, are submitted to the FDA as part of a NDA requesting approval to market the product candidate for a proposed indication. Under the Prescription Drug User Fee Act ("PDUFA") as amended, applicants are required to pay fees to the FDA for reviewing an NDA. These user fees, as well as the annual fees required for commercial manufacturing establishments and for approved products, can be substantial. Each NDA submitted to the FDA for approval is reviewed for administrative completeness and reviewability within 60 days following submission of the application. If found complete, the FDA will “file” the NDA, thus triggering a full review of the application. The FDA may refuse to file any NDA that it deems incomplete or not properly reviewable at the time of submission.

Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA has agreed to certain performance goals in the review of NDAs. Most applications for standard review drug products are reviewed within ten to twelve months; most NDAs for priority review drugs are reviewed in six to eight months. The review process for both standard and priority review may be extended by FDA for three additional months to consider certain late-submitted information, or information intended to clarify information already provided in the submission. 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.

Before approving a NDA, the FDA may inspect the facilities at which the product is manufactured or facilities that are significantly involved in the product development and distribution process, and will not approve the product unless cGMP compliance is satisfactory at such facilities. The FDA may deny approval of a NDA if applicable statutory or regulatory criteria are not satisfied, or it may require additional testing or information, which can delay the approval process. FDA approval of any application may include many delays or may never be granted. If a product is approved, the approval will specify the indicated uses for which the product may be marketed in the United States pursuant to that NDA, may require that warning statements be included in the product labeling, may require that additional studies or trials be conducted following approval as a condition of the approval, may impose restrictions and conditions on product distribution, prescribing or dispensing in the form of risk evaluation and mitigation strategies ("REMS"), or may impose other limitations. After evaluating the NDA and all related information, including any advisory committee recommendation, if applicable, and inspection reports regarding the manufacturing facilities and clinical trial sites, the FDA will issue an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and contains a statement of specific conditions that must be met in order to secure final approval of the NDA and may require additional clinical or non-clinical testing in a resubmission to the NDA in order for the FDA to reconsider the application. FDA has committed to reviewing such submissions in two or six months depending on the type of information included in the resubmission. 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.

Table of Contents

Once a product is approved, marketing the product for other indicated uses or making certain manufacturing or other changes requires FDA review and approval of a supplemental NDA or a new NDA, which may require additional clinical data and review fees. In addition, further post-marketing testing and surveillance to monitor the safety or efficacy of a product may be required. Also, product approvals may be withdrawn if compliance with regulatory standards is not maintained or if safety or manufacturing problems occur at any time following approval. In addition, new government requirements may be established that could delay or prevent regulatory approval of our product candidates under development.

Special FDA Expedited Review and Approval Programs

The FDA has various programs, including Fast Track designation, Breakthrough Therapy designation, Accelerated Approval, and Priority Review, which are intended to expedite or simplify the process for the development and FDA review of drugs that are intended for the treatment of serious or life-threatening diseases or conditions and demonstrate the potential to address unmet medical needs. The purpose of these programs is to provide important new drugs to patients earlier than under standard FDA review procedures.

Under the fast track program, the sponsor of a new product candidate may request that FDA designate the product candidate for a specific indication as a fast track drug concurrent with, or after, the filing of the IND for the product candidate. Fast track designation provides opportunities for frequent interactions with the FDA review team to expedite development and review of the product. FDA may initiate review of sections of a fast track drug’s NDA before the application is complete. This rolling review is available if the applicant provides, and FDA approves, a schedule for the submission of the remaining information and the applicant pays applicable user fees. However, FDA’s time period goal for reviewing an application does not begin until the last section of the NDA is submitted.

In addition, a sponsor can request breakthrough therapy designation for a drug if it is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Drugs designated as breakthrough therapies are eligible for intensive guidance from FDA on an efficient drug development program, organizational commitment to the development and review of the product including involvement of senior managers, and, like fast track products, are also eligible for rolling review of the NDA. Both fast track and breakthrough therapy products are also eligible for accelerated approval and/or priority review, if relevant criteria are met.

Under the FDA’s accelerated approval regulations, the FDA may approve a drug for a serious or life-threatening illness that provides meaningful therapeutic benefit to patients over existing treatments based upon a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments.

In clinical trials, a surrogate endpoint is a measurement of laboratory or clinical signs of a disease or condition that substitutes for a direct measurement of how a patient feels, functions, or survives. Surrogate endpoints can often be measured more easily or more rapidly than clinical endpoints. A product candidate approved on this basis is subject to rigorous post-marketing compliance requirements, including the completion of Phase 4 or post-approval clinical trials to confirm the effect on the clinical endpoint. Failure to conduct required post-approval studies, or confirm a clinical benefit during post-marketing studies, will allow FDA to withdraw the drug from the market on an expedited basis. All promotional materials for product candidates approved under accelerated approval regulations are subject to prior review by FDA.

Once a NDA is submitted for a product intended to treat a serious condition, the FDA may assign a priority review designation if FDA determines that the product, if approved, would provide a significant improvement in safety or effectiveness. A priority review means that the goal for the FDA to review an application is six months, rather than the standard review of ten months under current PDUFA guidelines. Under the current PDUFA agreement, for NDAs for new molecular entities, these six- and ten- month review periods are measured from the 60-day filing date rather than the receipt date, which typically adds approximately two months to the timeline for review from the date of submission. Most products that are eligible for fast track and/or breakthrough therapy designation are also likely to be considered appropriate to request and potentially receive a priority review. Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. In addition, the manufacturer of an investigational drug for a serious or life-threatening disease is required to make available, such as by posting on its website, its policy on responding to requests for expanded access. Furthermore, fast track designation, breakthrough therapy designation, accelerated approval and priority review do not change the standards for approval and may not ultimately expedite the development or approval process.

Post-approval requirements

Any drug products for which we receive FDA approval will be subject to continuing regulation by the FDA. Certain requirements include, inter alia, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information on an annual basis or more frequently for specific events, product sampling and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA promotion and advertising requirements. These promotion and advertising requirements include, among others, standards for direct-to-consumer advertising, prohibitions against promoting drugs for uses or patient populations that are not described in the drug’s approved labeling, known as “off-label use,” and other promotional activities, such as those considered to be false or misleading. Failure to comply with FDA requirements can have negative consequences, including the immediate discontinuation of noncomplying materials, adverse publicity, enforcement letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties. Such enforcement may also lead to scrutiny and enforcement by other government and regulatory bodies.

Although physicians may prescribe legally available drugs for off-label uses, manufacturers may not encourage, market or promote such off-label uses. As a result, “off-label promotion” has formed the basis for litigation under the Federal False Claims Act ("FCA") violations of which are subject to significant civil fines and penalties. In addition, under the federal Physician Payments Sunshine Act, manufacturers of certain prescription products are required to disclose annually to the Centers for Medicare & Medicaid Services ("CMS") payments or transfers of value made to “covered recipients” and teaching hospitals, and ownership or investment interests held by covered recipients and their immediate family members. Reportable payments and transfers of value may be direct or indirect, in cash or kind, for any reason, and are required to be disclosed even if the transfers are not related to an approved product. Failure to comply with the Physician Payments Sunshine Act could result in penalties up to $1.15 million per year.

The manufacturing of any of our product candidates, if approved, will be required to comply with applicable FDA manufacturing requirements contained in the FDA’s cGMP regulations. The FDA’s cGMP regulations require, among other things, quality control and quality assurance, as well as the corresponding maintenance of comprehensive records and documentation. Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are also required to register their establishments and list any products they make with the FDA and to comply with related requirements in certain states. These entities are further subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance.

Discovery of problems with a product after approval may result in serious and extensive restrictions or other consequences for a product, manufacturer or holder of an approved NDA, as well as lead to potential market disruptions. These restrictions or consequences may include untitled or warning letters, recalls, suspension of a product until the FDA is assured that quality standards can be met, and continuing oversight of manufacturing by the FDA under a “consent decree,” which frequently includes the imposition of costs and continuing inspections over a period of many years, as well as possible withdrawal of the product from the market. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

The FDA also may require post-marketing testing, or Phase IV testing, as well as REMS to monitor the effects of an approved product or place conditions on an approval that could otherwise restrict the distribution or use of approved products.

Pediatric trials and exclusivity

Even when not pursuing a pediatric indication, under the Pediatric Research Equity Act of 2003, an NDA or supplement thereto must contain data that are adequate to assess the safety and effectiveness of the drug product 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. With enactment of the Food and Drug Administration Safety and Innovation Act (the "FDASIA") in 2012, sponsors must also submit pediatric trial plans prior to the assessment data. Those plans must contain an outline of the proposed pediatric trials the applicant plans to conduct, including trial objectives and design, any deferral or waiver requests, and other information required by regulation. The applicant, the FDA, and the FDA’s internal review committee must then review the information submitted, consult with each other, and agree upon a final plan. The FDA or the applicant may request an amendment to the plan at any time.

16

Table of Contents

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. Additional requirements and procedures relating to deferral requests and requests for extension of deferrals are contained in the FDASIA.

Separately, in the event the FDA makes a written request for pediatric data relating to a drug product, an NDA sponsor who submits such data may be entitled to pediatric exclusivity. Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment of an additional 6 months of marketing protection to the term of any existing regulatory exclusivity, including the non-patent and orphan exclusivity.

Patent term restoration and extension

A patent claiming a new drug product may be eligible for a limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, generally referred to as the “Hatch-Waxman Act,” which permits an extension of the term of a patent for up to five years to compensate patent holders for marketing time lost while developing the product and awaiting government approval during the FDA regulatory review. The basis for the patent extension is the regulatory review period, which is basically composed of two parts, a testing phase and an approval phase, less a reduction, if any, in either part for a period time where there was a finding of lack of due diligence. The restoration period granted can be up to one-half the time between the effective date of an IND and the submission date of an NDA (testing phase), plus the time between the submission date of an NDA and the ultimate approval date (approval phase). Patent term extension cannot be used to extend the remaining term of a patent past a total of 14 years from the product’s approval date. In other words, the total maximum patent life for the product with the patent extension cannot exceed 14 years from the products approval date, which amounts to 14 years of potential marketing time. Only one patent applicable to an approved drug product may be extended, and the application for the extension must be submitted prior to the expiration of the patent in question and within 60 days of FDA approval. A patent that covers multiple drugs for which approval is sought can only be extended in connection with one of the approvals and the scope of the extended patent is limited to the approved drug. The USPTO reviews and approves the application for any patent term extension in consultation with the FDA. The term of a patent which claims a human drug product, a method of using the product, or a method of manufacturing the product may potentially be extended if it satisfies the various conditions including that it is the first permitted commercial marketing or use of the drug.

Review and approval of drug products outside the United States

In addition to regulations in the United States, we are subject to a variety of foreign regulations governing manufacturing, clinical trials, commercial sales and distribution of our future products. Whether or not we obtain FDA approval for a product candidate, we must obtain approval by the comparable regulatory authorities of foreign countries before commencing clinical trials or marketing in those countries. The approval process varies from country to country and can be subject to uncertainties, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

Regulation in the European Economic Area

In the European Economic Area ("EEA") which is composed of the Member States of the European Union plus Norway, Iceland and Liechtenstein, medicinal products can only be commercialized after obtaining a Marketing Authorization ("MA").

There are two types of MAs:

•The Community MA, which is issued by the European Commission through the Centralized Procedure, based on the opinion of the Committee for Medicinal Products for Human Use ("CHMP") of the European Medicines Agency ("EMA") and which is valid throughout the entire territory of the EEA. The Centralized Procedure is mandatory for certain types of products, such as biotechnology medicinal products, orphan medicinal products and medicinal products that contain a new active substance indicated for the treatment of AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune and viral diseases. The Centralized Procedure is optional for products containing a new active substance not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public health in the EU. Under the Centralized Procedure the maximum timeframe for the evaluation of a marketing authorization application ("MAA") is 210 days (excluding clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the CHMP). Accelerated evaluation might be granted by the CHMP in exceptional cases, when the authorization of a medicinal product is of major interest from the point of view of public health and in particular from the viewpoint of therapeutic innovation. Under the accelerated procedure the standard 210 days review period is reduced to 150 days.

17

Table of Contents

•National MAs, which are issued by the competent authorities of the Member States of the EEA and only cover their respective territory, are available for products not falling within the mandatory scope of the Centralized Procedure. Where a product has already been authorized for marketing in a Member State of the EEA, this National MA can be recognized in another Member State through the Mutual Recognition Procedure. If the product has not received a National MA in any Member State at the time of application, it can be approved simultaneously in various Member States through the Decentralized Procedure.

Prior to obtaining an MA in the EEA, applicants have to demonstrate compliance with all measures included in a Pediatric Investigation Plan ("PIP") approved by the EEA regulatory agency, covering all subsets of the pediatric population, unless the EEA regulatory agency has granted (1) a product-specific waiver, (2) a class waiver or (3) a deferral for one or more of the measures included in the PIP.

In the EEA, upon receiving a MA, new chemical entities generally receive eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in the EEA from referencing the innovator’s data to assess a generic application. During the additional two-year period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic product can be marketed until the expiration of the market exclusivity. However, there is no guarantee that a product will be considered by the EEA regulatory agencies to be a new chemical entity, and products may not qualify for data exclusivity.

Pharmaceutical coverage, pricing and reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product and any product candidates for which we obtain regulatory approval. In the United States and other markets, sales of any product, and any product candidates for which we receive regulatory approval for commercial sale, will depend in part on the availability of coverage and adequate reimbursement from third party payors. Third party payors include government health administrative authorities, managed care providers, private health insurers and other organizations. The process for determining whether a payor will provide coverage for a drug product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the drug product. Third party payors may limit coverage to specific drug products on an approved list, or formulary, which might not include all of the FDA-approved drug products for a particular indication.

Third party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. A payor may not consider a product to be medically necessary or cost-effective. Moreover, a payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved, or that other payors will similarly provide similar coverage for the product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.

CMS administers the Medicaid drug rebate program, in which pharmaceutical manufacturers pay quarterly rebates to each state Medicaid agency. Generally, for branded prescription drugs marketed under NDAs, manufacturers are required to rebate the greater of 23.1% of the average manufacturer price or the difference between such price and the best price during a specified period. An additional rebate for products marketed under NDAs is payable if the average manufacturer price increases at a rate higher than inflation, and other methodologies apply to new formulations of existing drugs. In addition, the Affordable Care Act (the "ACA") revised certain definitions used for purposes of calculating the rebates, including the definition of “average manufacturer price.” Various state Medicaid programs have implemented voluntary supplemental drug rebate programs that may provide states with additional manufacturer rebates in exchange for preferred status on a state’s formulary or for patient populations that are not included in the traditional Medicaid drug benefit coverage.

In the European Union, pricing and reimbursement schemes vary widely from country to country. Some countries provide that drug products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies or trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. For example, the European Union provides options for its member states to restrict the range of drug products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. European Union member states may approve a specific price for a drug product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the drug product on the market. Other member states allow companies to fix their own prices for drug products, but monitor and control company profits. The downward pressure on health care costs in general, and particularly on prescription drugs, has become intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert competitive pressure that may reduce pricing within a country. Any country that has price controls or reimbursement limitations for drug products may not allow favorable reimbursement and pricing arrangements.

Healthcare Reform

In March 2010, the then President of the United States signed one of the most significant healthcare reform measures in decades, the ACA. The ACA substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacted the pharmaceutical industry. This comprehensive legislative overhaul was expected to extend coverage to approximately 36 million previously uninsured Americans. The ACA also requires the pharmaceutical industry to share in the costs of reform by increasing Medicaid rebates and expanding Medicaid rebates to cover Medicaid managed care programs, among other things. The ACA also includes funding of pharmaceutical costs for Medicare patients in excess of the prescription drug coverage limit and below the catastrophic coverage threshold.

There have been executive, judicial, Congressional, and political challenges to certain aspects of the ACA. For example, the ACA's individual mandate was repealed by Congress in The Tax Cuts and Jobs Act of 2017 (the “Tax Act”), which was signed into law in December 2017 and became effective January 1, 2019. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas ruled that the individual mandate is a critical and inseverable feature of the ACA, and because it was repealed as part of the Tax Act, the remaining provisions of the ACA are invalid as well. Ultimately, on June 17, 2021, the U.S. Supreme Court held that state and individual plaintiffs did not have standing to challenge the individual mandate provision of the ACA; in so holding, the Supreme Court did not consider larger constitutional questions about the validity of this provision or the validity of the ACA in its entirety. In addition, there have been a number of health reform initiatives by the Biden administration that have impacted the ACA. For example, on August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (“IRA”) 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. It is possible that there will be additional health reform measures. It is unclear how any such challenges, if any, and other efforts to modify, repeal and replace the ACA will impact the ACA.

Further, there has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices, including several recent U.S. Congressional inquiries and federal and state legislation designed to, among other things, increase drug pricing transparency, expedite generic competition, review relationships between pricing and manufacturer patient assistance programs, and reform government program drug reimbursement methodologies. At the federal level, in July 2021, the Biden administration released an executive order that included multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, the U.S. Department of Health and Human Services (“HHS”) released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform. The plan sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. In addition, the IRA, among other things (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare and (ii) imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions will take effect progressively starting in fiscal year 2023, although they may be subject to legal challenges. In addition, the Biden administration released an additional executive order on October 14, 2022, directing HHS to report on how the Center for Medicare and Medicaid Innovation can be further leveraged to test new models for lowering drug costs for Medicare and Medicaid beneficiaries.

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. We anticipate that these and other healthcare reform efforts will continue to result in additional downward pressure on drug pricing. Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments from private payors.

Healthcare Laws

Healthcare providers, physicians and third party payors play a primary role in the recommendation and prescription of drug products that are granted marketing approval. Arrangements with healthcare providers, third party payors and other customers are subject to broadly applicable fraud and abuse and other healthcare laws and regulations. Such restrictions under applicable federal and state healthcare laws and regulations include the following:

•the federal healthcare Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be made, in whole or in part, under a federal healthcare program such as Medicare or Medicaid. The term “remuneration” has been broadly interpreted to include anything of value, including cash, improper discounts, and free or reduced price items and services. The intent standard under the federal Anti-Kickback Statute was amended by ACA to a stricter standard such that a person or entity no longer needs to have actual knowledge of the statute or

19

Table of Contents

specific intent to violate it in order to have committed a violation. Moreover, under the ACA, 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 federal civil FCA. Additionally, many states have similar laws that apply to their state health care programs as well as private payors. Violations of the federal or state anti-kickback laws can result in exclusion from federal and state health care programs and substantial civil and criminal penalties;

•the federal civil and criminal false claims laws and civil monetary penalties laws, including the federal FCA, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, false, fictitious or fraudulent claims for payment from Medicare, Medicaid or other federal healthcare programs, and knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government. Even where pharmaceutical companies do not submit claims directly to payors, they can be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers, promoting a product off-label, marketing products of sub-standard quality, or paying a kickback that results in a claim for items or services. In addition, activities relating to the reporting of wholesaler or estimated retail prices for pharmaceutical products, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state and third-party reimbursement for such products, and the sale and marketing of such products, are subject to scrutiny under this law. Private individuals or whistleblowers can bring FCA “qui tam” actions on behalf of the government and may share in amounts recovered. Proof of intent to deceive is not required to establish liability under the civil False Claims Act;

•the federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA") imposes criminal and civil liability for, among other things, executing or attempting to execute a scheme to defraud any healthcare benefit program, including any third party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements or representations, or making false statements relating to 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 to have committed a violation;

•HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act ("HITECH") and their implementing regulations, which imposes privacy, security, transmission and breach reporting obligations, including mandatory contractual terms, with respect to individually identifiable health information including PHI, upon “covered entities” subject to the law, such as health plans, healthcare clearinghouses and certain healthcare providers, and their respective business associates that perform services on their behalf that involve individually identifiable health information, including PHI. 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 laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. Other federal and state laws, such as the Federal Trade Commission Act, also impose requirements with respect to individuals' personal information;

•the federal Physician Payments Sunshine Act requires certain manufacturers of prescription drugs, devices and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program to annually report to CMS information related to payments and other transfers of value to physicians, dentists, optometrists, podiatrists, chiropractors, certain other healthcare professionals (such as nurse practitioners and physicians assistants), and teaching hospitals, and ownership and investment interests held by physicians and their immediate family members. In addition, Section 6004 of the ACA requires annual reporting of information about drug samples that manufacturers and authorized distributors provide to physicians; and

•analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply more broadly than their U.S. federal analogues, such as to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third party payors, including private insurers; state laws that require drug companies to comply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state and local laws that require the licensure of sales representatives; state laws that require drug manufacturers to report information related to drug pricing or payments and other transfers of value to healthcare providers or marketing expenditures and pricing information; data privacy and security laws and regulations in foreign jurisdictions that may be more stringent than those in the United States

20

(such as the European Union, which adopted the General Data Protection Regulation ("GDPR") which became effective in May 2018); state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts; and state laws related to insurance fraud in the case of claims involving private insurers.

If our operations are found to be in violation of any of the healthcare laws or regulations described above or any other healthcare regulations that apply to us, we may be subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, imprisonment, additional reporting obligations and oversight if we become subject to a corporate integrity agreement or consent decree, reputational harm, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and pursue our strategy.

Environmental, Health and Safety Matters

We are subject to extensive environmental, health and safety laws and regulations in a number of jurisdictions governing, among other things, (i) the use, storage, registration, handling, emission and disposal of chemicals, waste materials and sewage; and (ii) chemical, air, water and ground contamination, air emissions and the cleanup of contaminated sites, including any contamination that results from spills due to our failure to properly dispose of chemicals, waste materials and sewage.

These laws, regulations and permits could potentially require the expenditure by us of significant amounts for compliance or remediation. If we fail to comply with such laws, regulations or permits, we may be subject to fines and other civil, administrative or criminal sanctions, including the revocation of permits and licenses necessary to continue our business activities. In addition, we may be required to pay damages or civil judgments in respect of third party claims, including those relating to personal injury (including exposure to hazardous substances we use, store, handle, transport, manufacture or dispose of), property damage or contribution claims. Some environmental, health and safety laws allow for strict, joint and several liability for remediation costs, regardless of comparative fault. We may be identified as a responsible party under such laws. Such developments could have a material adverse effect on our business, financial condition and results of operations.

In addition, laws and regulations relating to environmental, health and safety matters are often subject to change. In the event of any changes or new laws or regulations, we could be subject to new compliance measures or to penalties for activities which were previously permitted.

The operations of our subcontractors and suppliers are also subject to various laws and regulations relating to environmental, health and safety matters, and their failure to comply with such laws and regulations could have a material adverse effect on our business and reputation, result in an interruption or delay in the development or manufacture of our product candidates, or increase the costs for the development or manufacture of our product candidates.

Human Capital

As of December 31, 2022, we had a total of 12 full-time employees. From time to time, we also retain independent contractors and consultants to support our organization. We believe our internal R&D capabilities coupled with our third-party R&D consultants are well positioned to execute our pipeline strategy in a cost effective manner. None of our employees are represented by a labor union, and we consider our employee relations to be good.

Attracting, retaining and developing employees from a diverse range of backgrounds to support our research, development and clinical activities is an integral part of our human capital strategy and we believe we offer competitive compensation (including salary, incentive bonus, and equity) and benefits packages.

Corporate Information

We were incorporated in October 2011 as a Delaware corporation under the name Tigercat Pharma, Inc. We changed our name to VYNE Therapeutics Inc. in September 2020, following the merger (the "Merger") between Foamix Pharmaceuticals Ltd. ("Foamix") and Menlo Therapeutics Inc. ("Menlo") in March 2020.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the "Securities Act") and as modified by the JOBS Act and a “smaller reporting company,” as defined in Rule 12b-2 of the Exchange Act. As such, we are eligible to take advantage of certain exemptions from various reporting requirements, such as the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, and certain reduced or scaled disclosure requirements available to smaller reporting companies.

ITEM 1A-RISK FACTORS

In conducting our business, we face many risks that may interfere with our business objectives. Some of these risks could materially and adversely affect our business, financial condition and results of operations. In particular, we are subject to various risks resulting from changing economic, political, industry, business and financial conditions. The risks and uncertainties described below are not the only ones we face. You should carefully consider the following factors and other information in this annual report. If any of the negative events referred to below occur, our business, financial condition and results of operations could suffer. In any such case, the trading price of our common stock could decline.

Risk Factors Summary

Our business is subject to numerous risks and uncertainties that you should be aware of in evaluating our business. These risks include, but are not limited to, the following:

•We will need substantial additional funding to fund our operations, and there is substantial doubt about our ability to continue as a going concern. If we cannot obtain substantial additional funding, we could be forced to delay, reduce or terminate our research and development activities which would have a material adverse effect on our financial condition;

•Our business is substantially dependent on the successful development of our BET inhibitor product candidates;

•We may be unable to develop a lead molecule for the VYN202 program and exercise our option to license the applicable BET inhibitor compounds from Tay;

•We may encounter delays in enrolling patients and successfully completing clinical trials for our product candidates, and may even be prevented from commencing such trials due to factors that are largely beyond our control;

•Clinical drug development is very expensive, time-consuming and uncertain. Our clinical trials may fail to adequately demonstrate the safety and efficacy of our current or any future product candidates, which could prevent or delay regulatory approval and commercialization;

•New chemical entities may require more time and resources for development, testing and regulatory approval;

•Our clinical trials may fail to demonstrate the safety and efficacy of our product candidates, or serious adverse or unacceptable side effects may be identified during the development of our product candidates, which could result in the abandonment or limitation of the development of our product candidates or prevent or delay our ability to pursue strategic alternatives for our product candidates;

•Results obtained in non-clinical studies and completed clinical trials may not predict success in later clinical trials;

•Topline and preliminary data from our clinical trials that we announce or publish from time to time may change as additional data become available and are subject to audit and verification procedures that could result in material changes in the final data;

•We have a limited history as a clinical-stage biopharmaceutical company developing product candidates for immuno-inflammatory conditions, which may make it difficult to assess our future viability;

•We may spend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success;

•We are subject to various risks and uncertainties arising out of the completed divestiture of our commercial business;

22

Table of Contents

•We have not obtained regulatory approvals to market our other pipeline product candidates, and we may be delayed in obtaining or fail to obtain such regulatory approvals and to commercialize these product candidates;

•Our failure to successfully in-license, acquire, develop and market additional product candidates or approved products could impair our ability to grow our business;

•We intend to engage in strategic transactions, which could impact our liquidity, increase our expenses and present significant distractions to our management;

•We may decide not to continue developing any of our product candidates at any time during development or of any of our products after approval, which would reduce or eliminate our potential return on investment for those product candidates or products;

•The COVID-19 pandemic could adversely affect our operations, including at ourclinical trial sites, as well as the business or operations of our manufacturers, contract research organizations or other third parties with whom we conduct business;

•We are subject to various U.S. federal, state, local and foreign health care fraud and abuse laws, including anti-kickback, self-referral, false claims and fraud laws, health information privacy and security, and transparency laws, and any violations by us of such laws could result in substantial penalties or other consequences including criminal sanctions, civil penalties, contractual damages, reputational harm, and diminished profits and future earnings. Additionally, any challenge to or investigation into our practices under these laws could cause adverse publicity and be costly to respond to, and thus could harm our business;

•Legislative or regulatory healthcare reforms in the United States may make it more difficult and costly for us to obtain regulatory clearance or approval of our product candidates and to produce, market, and distribute our products after clearance or approval is obtained; and

•The trading price of the shares of our common stock is volatile, and stockholders could incur substantial losses.

Risks Related to our Financial Position and Need for Capital

We will need substantial additional funding to fund our operations, and there is substantial doubt about our ability to continue as a going concern. If we cannot obtain substantial additional funding, we could be forced to delay, reduce or terminate our research and development activities which would have a material adverse effect on our financial condition.

Developing and commercializing biopharmaceutical products and conducting preclinical studies and clinical trials is an expensive and highly uncertain process that takes years to complete. As of December 31, 2022, we had approximately $31.0 million in cash, cash equivalents and restricted cash. We received an additional $5.0 million deferred payment in January 2023 from the sale of our MST Franchise. Based on our current operating plan, we do not have sufficient cash and cash equivalents to fund our anticipated level of operations as they become due during the twelve months following the date of the issuance of the financial statements included herein. Our estimates may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Further, changing circumstances, some of which may be beyond our control, could cause us to consume capital significantly faster than we currently anticipate, and we may need to seek additional funds sooner than planned. The aforementioned factors raise substantial doubt about our ability to continue as a going concern, as reflected in the audit report included with the audited financial statements included elsewhere in this report. In addition, see “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity” for further discussion regarding our liquidity. We may not be able to raise any proceeds from financing transactions. Accordingly, additional funds may not be obtained for our ongoing operations and we may not succeed in our future operations. Unless we are able to raise additional capital to finance our operations, our long-term business plan may not be accomplished, and we may be forced to cease, reduce, or delay operations, including our product candidate programs.

Our future capital requirements depend on many factors, including:

•milestone payments associated with our development programs;

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

•the scope, progress, results and costs of preclinical development, laboratory testing and conducting preclinical and clinical trials for our product candidates;

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

•the extent to which we in-license or acquire additional product candidates and technologies;

23

Table of Contents

•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;

•the impact on the timing of our preclinical studies, on the recruitment, enrollment, conduct and timing of our clinical trials, and on our business, due to the COVID-19 pandemic or any other external or macroeconomic factors;

•our headcount and associated costs as we expand our research and development infrastructure;

•our ability to identify and consummate transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize our product candidates, and earn revenue from such arrangements; and

•the ongoing costs of operating as a public company.

Additional capital may not be available when we need it, on terms that are acceptable to us or at all. If adequate funds are not available to us on a timely basis, we may be required to revise our operating plan in order to:

•delay, limit, reduce or terminate our research and development activities; or

•delay, limit, reduce or terminate preclinical studies, clinical trials or other development activities for our product candidates.

If we raise additional capital through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish certain valuable rights to our product candidates, technologies, future revenue streams or research programs or grant licenses on terms that may not be favorable to us. If we raise additional capital through public or private equity offerings, the ownership interest of our existing shareholders will be diluted and the terms of any new debt securities or equity securities may have a preference over our common stock. In addition, if we issue warrants or preferred stock in connection with our financing activities, such securities may include terms that are unfavorable to our stockholders, including anti-dilution provisions and other preferences. In addition, any holders of preferred stock may receive preferential voting rights that are superior to the voting rights of holders of our common stock. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt or making capital expenditures or specified financial ratios, any of which could restrict our ability to operate our business.

We have incurred significant losses since our inception and we anticipate that we will continue to incur significant losses for the foreseeable future, which could harm our future business prospects.

We have historically incurred substantial net losses, including net losses of $23.2 million and $73.3 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of $662.7 million. We expect our losses to continue as we continue to devote a substantial portion of our resources to our research and development efforts. These losses have had, and will continue to have, an adverse effect on our working capital, total assets, and shareholders’ equity. Because of the numerous risks and uncertainties associated with our research and development, we are unable to predict when we will become profitable, and we may never become profitable. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our inability to achieve and then maintain profitability would negatively affect our business, financial condition, results of operations, and cash flows.

We anticipate that our expenses will increase substantially if and as we:

•continue to develop product candidates and conduct preclinical studies and clinical trials;

•initiate and continue research and development, including preclinical, clinical and discovery efforts for any future product candidates;

•seek to identify additional product candidates;

•seek regulatory approvals for our product candidates that may successfully complete clinical development;

•add operational, financial and management information systems and personnel, including personnel to support our product candidate development and help us comply with our obligations as a public company;

•hire and retain additional personnel, such as clinical, quality control, scientific, and administrative personnel;

•maintain, expand and protect our intellectual property portfolio;

•add equipment and physical infrastructure to support our research and development; and

•acquire or in-license other product candidates and technologies.

Our expenses could increase beyond our expectations if we are required by the U.S. Food and Drug Administration (the “FDA”), or other regulatory authorities to perform clinical trials in addition to those that we currently expect.

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.

24

Table of Contents

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 instructions, 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 under which Cantor Fitzgerald is acting as our sales agent, is 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 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.

In addition, on March 15, 2022, we entered into a purchase agreement (the "Equity Purchase Agreement") with Lincoln Park Capital Fund, LLC ("Lincoln Park") which provides that, upon the terms and subject to the conditions and limitations set forth therein, we have the right, but not the obligation, to sell to Lincoln Park up to $30.0 million of shares of our common stock over the 36-month term of the Equity Purchase Agreement. Upon execution of the Equity Purchase Agreement, we issued 92,644 shares of our common stock to Lincoln Park as commitment shares in accordance with the closing conditions contained within the Equity Purchase Agreement. We may be limited in the amount of shares we can sell pursuant to the terms of the Equity Purchase Agreement. For example, we are prohibited from directing Lincoln Park to purchase shares under the Equity Purchase Agreement if such purchase would result in Lincoln Park beneficially owning more than 9.99% of our total outstanding shares. In addition, under applicable rules of Nasdaq, in no event may we issue or sell to Lincoln Park under the Equity Purchase Agreement shares of our common stock, including the commitment shares, in excess of 19.99% of the shares of our common stock outstanding immediately prior to the execution of the Equity Purchase Agreement (the "Exchange Cap") unless (i) we obtain stockholder approval to issue shares of our common stock in excess of the Exchange Cap or (ii) the average price of all applicable sales of our common stock to Lincoln Park under the Equity Purchase Agreement equals or exceeds the minimum price per share as mandated by Nasdaq rules. If any of the foregoing occur, we will be limited in the amount of proceeds we will be able to raise under the Equity Purchase Agreement which could have a material adverse effect on our financial condition and liquidity.

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

We currently expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. 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, anti-dilution protection or other preferences that adversely affect your rights as a stockholder. Debt 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. In addition, we may opportunistically seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans.

If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs 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, reduce or terminate our product development or grant rights to third parties to develop product candidates that we would otherwise prefer to develop ourselves.

Risks Related to Development of Our Product Candidates

We may be unable to develop a lead molecule for the VYN202 program and exercise our Option to license the applicable Oral BETi Compounds from Tay.

As discussed in "Item 1. Business—Development and License Agreements—Agreements with Tay Therapeutics," under the terms of the Option Agreement, as amended, our Option to exercise our rights with respect to Tay's highly selective BET inhibitor compounds expires on April 30, 2023. We are currently working with Tay to complete our assessment of several compounds that may be suitable for the program. However, we may be unable to select a viable lead molecule in a timely manner or at all. If we are unable to exercise the Option, we may be forced to terminate the program and would have a material adverse effect on our ability to execute our strategy of enhancing our pipeline.

Our product candidates are in early stages of development and may fail in development or suffer delays that materially and adversely affect their commercial viability. If we are unable to complete development of, or commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed.

25

Table of Contents

All of our product candidates are in early stages of development. We only recently commenced a Phase 1a/b clinical trial evaluating our lead candidate, VYN201, for the treatment of nonsegmental vitiligo in November 2022. In addition, our VYN202 program is in preclinical development and may never advance to clinical-stage development. Our ability to achieve and sustain profitability depends on obtaining regulatory approvals for, and successfully commercializing our product candidates, either alone or with third parties, and we cannot guarantee you that we will ever obtain regulatory approval for any of our product candidates. We have limited experience in conducting and managing the clinical trials necessary to obtain regulatory approvals including approval by the FDA. Before obtaining regulatory approval for the commercial distribution of our product candidates, we or an existing or future collaborator must conduct extensive preclinical tests and clinical trials to demonstrate the safety and efficacy in humans of our product candidates.

We may not have the resources to advance the development of our therapeutics candidates if we experience issues that delay or prevent the regulatory approval of, or our ability to commercialize, our product candidates, including:

•negative or inconclusive results from our clinical trials, leading to a decision or requirement to conduct additional preclinical testing or clinical trials or abandon a program;

•preclinical study results, including toxicology data, may show the product candidate to be less effective than desired or to have harmful or problematic side effects;

•product-related side effects experienced by patients in our clinical trials or by individuals using drugs or therapeutics similar to our product candidates;

•our third-party manufacturers’ inability to successfully manufacture our therapeutics in sufficient quantities or at all;

•inability of any third-party contract manufacturer to scale up manufacturing of our product candidates and those of our collaborators to supply the needs of clinical trials;

•delays in enrolling patients in our clinical trials;

•harmful side effects or inability of our product candidates to meet efficacy endpoints during clinical trials;

•inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;

•greater than anticipated costs of our clinical trials;

•manufacturing costs, formulation issues, pricing or reimbursement issues, or other factors that no longer make a product candidate economically feasible;

•delays and changes in regulatory requirements, policy and guidelines, including the imposition of additional regulatory oversight around clinical testing generally or with respect to our technology in particular or as a result of the impacts of the COVID-19 pandemic; and

•varying interpretations of our data by the FDA and similar foreign regulatory agencies.

Our inability to advance or complete the development of our product candidates, or significant delays in doing so, could have a material and adverse effect on our business, financial condition, results of operations and prospects.

Our business is substantially dependent on the successful development of our BET inhibitor product candidates.

In January 2022, we divested our commercial business, the MST Franchise, in order to focus our efforts and resources on drug development. Our current development pipeline primarily consists of our BET inhibitor product candidates, VYN201 and VYN202, which we are developing for the treatment of immuno-inflammatory diseases. The success of our business is dependent on our successful development and/or our ability to pursue strategic initiatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize, these product candidates.

Our ability to successfully progress these candidates may be hampered for many reasons, including:

26

Table of Contents

•a product candidate may in a clinical trial be shown to have harmful side effects or other characteristics that indicate it is unlikely to be effective or otherwise does not meet applicable regulatory criteria;

•competitors may develop alternatives that render our product candidates obsolete or less attractive;

•product candidates we develop may nevertheless be covered by third parties’ patents or other proprietary rights;

•a product candidate may not be capable of being produced in commercial quantities at an acceptable cost, or at all;

•a product candidate may not be accepted as safe and effective by patients, the medical community or third party payors, if applicable;

•creation of intellectual property rights, such as patents, which are necessary to protect our interests in a product candidate, can be challenging in relation to pharmaceutical formulations and their uses with known active pharmaceutical ingredients and generally used combinations of inactive ingredients approved by the FDA;

•intellectual property rights, such as patents, which are necessary to protect our interests in a product candidate, may be difficult to obtain or unobtainable or if obtained may be difficult to enforce or unenforceable; and

•intellectual property rights, such as patents, may fail to provide adequate protection, may be challenged and one or more claims may be revoked or the patent may be held to be invalid.

Furthermore, VYN201 and VYN202 are very early stage programs. The development of these new chemical entities carries even greater risk and a higher probability of failure. Our failure to successfully develop our product candidates will have a material adverse effect on our business and financial condition.

We may encounter delays in enrolling patients and successfully completing clinical trials for our product candidates and may even be prevented from commencing such trials due to factors that are largely beyond our control.

We have in the past experienced and may in the future experience delays in completing clinical trials and in commencing future clinical trials, including due to reasons associated with COVID-19. For example, in 2022, we experienced delays in enrolling patients in our Phase 2a clinical trial evaluating FMX114 for the treatment of atopic dermatitis ("AD"), a program for which we are not currently making any additional investment in, due to COVID-19 related issues. We rely on contract research organizations ("CROs") and clinical trial sites to ensure the proper and timely conduct of our clinical trials. While we have agreements governing the committed activities of our CROs, we have limited influence over their actual performance. A failure of one or more of our clinical trials can occur at any time during the clinical trial process. Clinical trials can be delayed or aborted for a variety of other reasons, including delay or failure to:

•obtain regulatory approval to commence a trial;

•reach agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which may be subject to extensive negotiation and vary significantly among different CROs and trial sites;

•obtain approval from an institutional review board (“IRB”) at each site;

•enlist an adequate number of suitable patients to participate in a trial;

•have patients complete a trial or return for post-treatment follow-up;

•ensure clinical sites observe trial protocol or continue to participate in a trial;

•address any patient safety concerns that arise during the course of a trial;

•address any conflicts with new or existing laws or regulations;

•add a sufficient number of clinical trial sites; or

•manufacture sufficient quantities of the product candidate for use in clinical trials.

Patient enrollment is also a significant factor in the timing of clinical trials and is affected by many factors, including the size and nature of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to available alternatives, including any new drugs or treatments that may be approved for the indications we are investigating.

We may also encounter delays if a clinical trial is suspended or terminated by us, the IRB of the institutions in which such trials are being conducted, by the trial’s data safety monitoring board, or by the FDA. Such authorities may suspend or terminate one or more of our clinical trials due to a number of factors, including our failure to conduct the clinical trial in accordance with relevant regulatory requirements or clinical protocols, inspection of the clinical trial operations or trial site by the FDA resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

If we experience delays in carrying out or completing any clinical trial of our product candidates, the commercial prospects of our product candidates may 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 significantly harm our business and financial condition. 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.

Clinical drug development is very expensive, time-consuming and uncertain. Our clinical trials may fail to adequately demonstrate the safety and efficacy of our current or any future product candidates, which could prevent or delay regulatory approval and commercialization.

Clinical drug development is very expensive, time-consuming and difficult to design and implement, and its outcome is inherently uncertain, particularly as it relates to new chemical entities. Before obtaining regulatory approval for the commercial sale of a product candidate, we must demonstrate through clinical trials that a product candidate is both safe and effective for use in the target indication. Most product candidates that commence clinical trials are never approved by regulatory authorities for commercialization. The clinical trials for these product candidates may take significantly longer than expected to complete. In addition, we, any partner with which we may in the future collaborate, the FDA, an IRB or other regulatory authorities, including state and local agencies and counterpart agencies in foreign countries, may suspend, delay, require modifications to or terminate our clinical trials at any time, for various reasons, including:

•lack of effectiveness of any product candidate during clinical trials or the failure of a product candidate to meet specified endpoints;

•discovery of serious or unexpected side effects experienced by trial participants, toxicities or other safety issues;

•slower than expected rates of subject recruitment and patient enrollment in clinical trials resulting from numerous factors, including COVID-19 or the prevalence of clinical trials for our competitors for their product candidates treating the same indication;

•difficulty in retaining subjects who have initiated participation in a clinical trial but may withdraw at any time due to adverse side effects from the therapy, insufficient efficacy, fatigue with the clinical trial process or for any other reason;

•difficulty in obtaining IRB approval for studies to be conducted at each site;

•delays in manufacturing or obtaining, or inability to manufacture or obtain, sufficient quantities of materials for use in clinical trials;

•inadequacy of or changes in our manufacturing process or the product formulation or method of delivery;

•changes in applicable laws, regulations and regulatory policies;

•delays or failure in reaching agreement on acceptable terms in clinical trial contracts or protocols with prospective CROs, clinical trial sites and other third-party contractors;

•inability to add a sufficient number of clinical trial sites;

•uncertainty regarding proper dosing;

•failure of our CROs or other third-party contractors to comply with contractual and regulatory requirements or to perform their services in a timely or acceptable manner;

•failure by us, our employees, our CROs or their employees or any partner with which we may collaborate or their employees to comply with applicable FDA or other regulatory requirements relating to the conduct of clinical trials or the handling, storage, security and recordkeeping for drug and biologic products;

•scheduling conflicts with participating clinicians and clinical institutions;

•failure to design appropriate clinical trial protocols;

•inability or unwillingness of medical investigators to follow our clinical protocols;

•difficulty in maintaining contact with subjects during or after treatment, which may result in incomplete data; and

•insufficient data to support regulatory approval.

If we experience delays in the completion of, or if we terminate, any of our future clinical trials, our business, financial condition, operating results and prospects would be adversely affected.

New chemical entities may require more time and resources for development, testing and regulatory approval.

Our BET inhibitor program is in the early stages of development, involves a novel therapeutic approach and new chemical entities, requires significant further research and development and regulatory approvals and is subject to the risks of failure inherent in the development of products based on innovative approaches. New chemical entities derived from our InhiBET platform are molecules that have not previously been approved and marketed as therapeutics. As a result, the product candidates from our InhiBET platform may face greater risk of unanticipated safety issues or other side-effects, or may not demonstrate efficacy. Further, the regulatory pathway for our new chemical entities may be more demanding.

Our clinical trials may fail to demonstrate the safety and efficacy of our product candidates, or serious adverse or unacceptable side effects may be identified during the development of our product candidates, which could result in the abandonment or limitation of the development of our product candidates or prevent or delay our ability to pursue strategic alternatives for our product candidates.

If our product candidates are associated with side effects in preclinical studies and/or clinical trials or have characteristics that are unexpected, our development costs could increase or we may need to abandon development activities or limit development to more narrow uses in which the side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. The FDA or an IRB may also require that we suspend, discontinue, or limit our clinical trials based on safety information. Such findings could result in regulatory authorities failing to provide marketing authorization for our product candidates. Many product candidates that initially showed promise in early stage testing have later been found to cause side effects that prevented further development of the product candidate.

Before any potential third-party partners can obtain marketing approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that our product candidates are both safe and effective for use in each target indication, and failures can occur at any stage of testing. Additionally, if we or others identify undesirable side effects caused by our drugs, a number of potentially significant negative consequences could result, including:

•we may need to abandon the development or limit the further development of our product candidates, including in various populations and for certain indications;

•we could be sued and held liable for harm caused to patients;

•our reputation may suffer;

•regulatory authorities may withdraw approval to market such product;

•regulatory authorities may require additional warnings on the product labeling;

•a medication guide outlining the risks of such side effects for distribution to patients may be required; and

•our ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize our product candidates would be harmed.

Any of these events could prevent us from pursuing strategic alternatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize the particular product candidate and could significantly harm our business, results of operations and prospects.

Results obtained in preclinical studies and completed clinical trials may not predict success in later clinical trials.

Success in preclinical testing, such as testing for VYN201, and early clinical trials does not ensure that later clinical trials will be successful, and any other clinical trials that we may conduct may not demonstrate consistent or adequate efficacy and safety to obtain regulatory approval to market our product candidates in any indication. We and other companies in the biopharmaceutical industry have frequently suffered significant setbacks in later clinical trials, even after achieving promising results in earlier non-clinical studies or clinical trials. For example, in August 2022, our Phase 2a clinical trial for FMX114 did not meet its primary endpoint of improving symptoms and severity of AD after four weeks of treatment. In addition, Phase 3 clinical trials often produce unsatisfactory results even though prior clinical trials were successful. Any of these events could prevent us from pursuing strategic alternatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize a particular product candidate and could significantly harm our business, results of operations and prospects.

Topline and preliminary data from our clinical trials that we announce or publish from time to time may change as additional data become available and are subject to audit and verification procedures that could result in material changes in the final data.

We may publicly disclose topline or preliminary data from our clinical trials which are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a complete analysis of all data related to the trial. We also make certain assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the topline or preliminary results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. Accordingly, topline and preliminary data should not be considered complete and should be viewed with caution

29

until the final data are available. We may also disclose interim data from our clinical trials. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as subject enrollment continues and more subject data become available. Adverse differences between interim, topline or preliminary data and final data could significantly harm our reputation and business prospects. Further, disclosure of interim, topline or preliminary data by us or by our competitors could result in volatility in the price of our common stock.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the potential of the particular program, the likelihood of marketing approval or commercialization of the particular product candidate, any approved product, and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is derived from information that is typically extensive, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular program, product candidate or our business.

If the interim, topline or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Our current and future clinical trials or those of any future collaborators may reveal significant adverse events not seen in our preclinical studies and may result in a safety profile that could inhibit regulatory approval or market acceptance of any of our product candidates.

If significant adverse events or other side effects are observed in any of our current or future clinical trials, we may have difficulty recruiting patients to such trials, patients may drop out of our trials, or we may be required to abandon the trials or our development efforts of one or more product candidates altogether. For example, certain BET inhibitors have been linked to tolerability issues, particularly in the gastrointestinal tract. We, the FDA or other applicable regulatory authorities, or an IRB may suspend any clinical trials of any product candidate at any time for various reasons, including a belief that subjects or patients in such trials are being exposed to unacceptable health risks or adverse side effects. Some potential therapeutics developed in the biotechnology industry that initially showed therapeutic promise in early-stage trials have later been found to cause side effects that prevented their further development. Even if the side effects do not preclude the product candidate from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance of the approved therapeutic due to its tolerability versus other therapies. Any of these developments could materially harm our business, financial condition and prospects.

We have a limited history as a clinical-stage biopharmaceutical company developing product candidates for immuno-inflammatory conditions, which may make it difficult to assess our future viability.

Our team has limited experience in developing drugs for the treatment of immuno-inflammatory conditions. 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 history of being a clinical-stage biopharmaceutical company focused on developing drugs in this area. We may also encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business objectives.

We may spend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

We have chosen to evaluate VYN201 in the treatment of nonsegmental vitiligo. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. For example, during 2022, we decided not to pursue further development of FMX114 for the treatment of AD and instead to focus our research and development efforts on VYN201 and VYN202. Our resource allocation decisions may cause us to fail to capitalize on viable commercial drugs or profitable market opportunities. Our spending on current and future development programs and product candidates for specific indications may not yield any commercially viable drugs. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through partnerships, licensing or other arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

We face competition from entities that have developed or may develop product candidates for the diseases addressed by our product candidates, including companies developing novel treatments and technology platforms. If these companies develop

30

Table of Contents

technologies or product candidates more rapidly than we do or their technologies are more effective, our ability to develop and successfully commercialize product candidates may be adversely affected.

The development and commercialization of drugs is extremely competitive. Our product candidates, if approved, will face significant competition and our failure to effectively compete may prevent us from achieving significant market penetration. Most of our competitors have significantly greater resources than we do, and we may not be able to successfully compete. We compete with a variety of multinational biopharmaceutical companies, specialized biotechnology companies and emerging biotechnology companies, as well as with technologies and product candidates being developed at universities and other research institutions. Our competitors have developed, are developing or will develop product candidates and processes competitive with our product candidates and processes. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community and any new treatments, including those based on novel technology platforms that enter the market. We believe that a significant number of products are currently under development, and may become commercially available in the future, for the treatment of conditions for which we are trying, or may try, to develop product candidates. There is intense and rapidly evolving competition in the biotechnology and biopharmaceutical fields. Competition from many sources exists or may arise in the future. Our competitors include larger and better funded biopharmaceutical, biotechnological and therapeutics companies, including companies focused on therapeutics for autoimmune diseases, fibrosis and cancer, as well as numerous small companies. Moreover, we also compete with current and future therapeutics developed at universities and other research institutions. Some of these companies are well-capitalized and, in contrast to us, have significant clinical experience, and may include our existing or future collaborators. In addition, these companies compete with us in recruiting scientific and managerial talent. Our success will depend partially on our ability to develop and commercialize therapeutics that are safer and more effective than competing therapeutics. Our commercial opportunity and success will be reduced or eliminated if competing therapeutics are safer, more effective, or less expensive than the therapeutics we develop.

We have not obtained regulatory approvals to market our product candidates, and we may be delayed in obtaining or fail to obtain such regulatory approvals and to commercialize these product candidates.

The process of developing, obtaining regulatory approval for and commercializing our other product candidates is long, complex, costly and uncertain, and delays or failure can occur at any stage. Furthermore, the research, testing, manufacturing, labeling, marketing, sale and distribution of drugs are subject to extensive and rigorous regulation by the FDA. We are not permitted to market any of our product candidates in the United States until we receive approval of the applicable NDA from the FDA. To gain approval of an NDA or other equivalent regulatory approval, we must provide the FDA with clinical data and other information that demonstrates the continued safety and efficacy of the product for the intended indication.

Even if we believe our clinical trials were successful, the FDA may require that we conduct additional clinical, nonclinical, manufacturing, validation or drug product quality studies and submit that data before considering or reconsidering any NDA we may submit. Depending on the extent of these additional studies, approval of any applications that we submit may be significantly delayed or may require us to expend more resources than we have available. It is also possible that additional studies we conduct may not be considered sufficient by the FDA to provide regulatory approval.

If any of these outcomes occur, we would not receive approval for our other product candidates and may need to discontinue the development of such product candidates.

The COVID-19 pandemic could adversely affect our operations, including at our clinical trial sites, as well as the business or operations of our manufacturers, contract research organizations or other third parties with whom we conduct business.

Our business has been adversely affected by the effects of the COVID-19 pandemic, which has resulted in a variety of restrictions in order to reduce the spread of the disease, which, among other things, direct businesses and governmental agencies to cease non-essential operations at physical locations, prohibit certain non-essential gatherings, and order cessation of non-essential travel. For example, enrollment and other operations related to our Phase 1b/2a clinical trial for FMX114 in Australia were negatively impacted by the COVID-19 pandemic and restrictions imposed by Australian authorities in 2022. In addition, some of our third-party preclinical science partners and manufacturers which we use for the supply of materials for our product candidates or other materials necessary to manufacture drug product to conduct preclinical studies and clinical trials are located in countries affected by COVID-19, particularly in China, and should they experience disruptions, such as lockdowns, temporary closures or suspension of services, we would likely experience delays in advancing these studies and trials. Any delay in the development of our product candidates could have a material adverse effect on our business and results of operations.

31

Even if our product candidates receive marketing approval, we may continue to face future developmental and regulatory difficulties. In addition, we are subject to government regulations and we may experience delays in obtaining required regulatory approvals to market our proposed product candidates.

Even if we receive approval of any regulatory filing for our product candidates, the FDA may grant approval contingent on the performance of additional costly post-approval clinical trials or REMS to monitor the safety or efficacy of the product, which could negatively impact us by reducing revenues or increasing expenses, and cause the product not to be commercially viable. Absence of long-term safety data may further limit the approved uses of products.

The FDA may also approve our product candidates for a more limited indication or a narrower patient population than we originally requested, or may not approve the labeling that we believe is necessary or desirable for the successful commercialization of our product candidates. Furthermore, any such approved product will remain subject to extensive regulatory requirements, including requirements relating to manufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion, distribution and recordkeeping.

If we fail to comply with the regulatory requirements of the FDA, or if we discover previously unknown problems with any approved commercial products, manufacturers or manufacturing processes, we could be subject to administrative or judicially imposed sanctions or other setbacks, which could require us to take corrective actions, including to:

•suspend or impose restrictions on operations, including costly new manufacturing requirements;

•refuse to approve pending applications or supplements to applications;

•suspend any ongoing clinical trials;

•suspend or withdraw marketing approval;
