Important milestone achieved as part of the Company’s new corporate strategy to develop treatments for immuno-inflammatory diseases

Topline results anticipated in early Q1 2022

BRIDGEWATER, NJ, USA I October 19, 2021 I VYNE Therapeutics Inc. (Nasdaq: VYNE) (“VYNE” or the “Company”) today announced that it has enrolled the first patient in its Phase 1b/2a clinical trial evaluating FMX114 for the treatment of mild-to-moderate atopic dermatitis (AD).

FMX114 is VYNE’s proprietary investigational combination gel formulation of tofacitinib and fingolimod. The product is being developed to address both the source and cause of inflammation in AD by developing a distinct combination of tofacitinib (a Janus kinase inhibitor aimed at reducing inflammation by inhibiting cytokine release from inflammatory cells) and fingolimod (a Sphingosine 1-phosphate receptor modulator) which approaches the reduction of inflammation by inhibiting migration of inflammatory cells, and in addition may also directly support skin barrier recovery. FMX114 has the potential to be the first topical combination JAK inhibitor for the treatment of AD as well as the first topical product in clinical development that utilizes the sphingosine 1-phosphate receptor mode of action.

The planned 25 patient Phase 2a study comparing the safety and efficacy of FMX114 gel with vehicle gel will also incorporate a preliminary Phase 1b evaluation of the safety and pharmacokinetics of FMX114 in 6 patients with mild to moderate atopic dermatitis for up to two weeks.

Dr. Iain Stuart, Chief Scientific Officer of VYNE, stated, “With FMX114, VYNE is further leveraging our extensive drug development capabilities by providing another unique targeted therapy with difficult-to-formulate active ingredients. FMX114 has been specifically designed to mitigate systemic exposure to tofacitinib and fingolimod while concentrating their respective anti-inflammatory and barrier repair properties in the skin. In light of the FDA’s recent review of the oral JAK inhibitor class for the treatment of several systemic autoimmune diseases, we believe it’s important to characterize the preliminary safety and pharmacokinetic profile of FMX114. The Phase 1b portion of the study will generate meaningful data as we advance the product into the Phase 2a portion for broader safety and efficacy evaluation.”

“FMX114 is an important addition to VYNE’s clinical development pipeline, and we are pleased to have enrolled the first patient in this trial,” said David Domzalski, Chief Executive Officer of VYNE. “Advancement of this innovative combination product is consistent with our corporate mission to improve the lives of patients by developing proprietary and differentiated therapies. We look forward to providing additional updates on the progress of our FMX114 program and anticipate topline results early in the first quarter of next year.”

The Phase 1b/2a study is a randomized, double-blinded trial designed to compare the safety and efficacy of FMX114 gel with vehicle gel. The study is expected to enroll 31 subjects, with each subject serving as their own control. The enrollment criteria specifies that subjects must have two comparable target AD lesions for treatment upon entry. Participants will have FMX114 gel applied to one of these lesions and vehicle gel to the other. Six subjects will be initially treated twice daily with FMX114 and vehicle for up to two weeks to evaluate preliminary safety of FMX114 and the pharmacokinetics of tofacitinib, fingolimod and fingolimod 1-phosphate. A further 25 subjects will receive FMX114 and vehicle treatment applied twice daily for four weeks in a double-blinded phase of the study to further evaluate safety, pharmacokinetics and efficacy. After completion of this phase, these subjects may continue into a two-week open-label treatment phase and will be able to apply the active drug to both lesions.

About Atopic Dermatitis
Atopic dermatitis (AD) is a chronic, severe form of eczema that is characterized by the appearance of dry, red, and itchy skin. AD most commonly affects the cheeks, arms, and legs. Flare ups often occur and symptoms can worsen leading to more-intense itching and more open sores. AD flares are triggered by stress, temperature changes, sweat, various skin irritants, and allergies. AD can have a wide-ranging impact on quality of life and there is a substantial monetary burden from direct and indirect costs to this patient population. While AD happens most often in children, it can develop at any point in a person’s lifetime and affects approximately 30 million people in the U.S. alone. Approximately 22 million of those diagnosed are on treatment, with 19 million registering mild to moderate disease. The rashes tend to flare and go away, but then come back again. According to Symphony Health data, there were over 7 million prescriptions written in 2019 alone for the treatment of AD.
