VYNE Therapeutics Announces Development Program for FMX114 Combination Topical Gel for Mild-to-Moderate Atopic Dermatitis
Announces promising preclinical data on FMX114
Phase 2a clinical study in AD expected to begin in 3Q 2021 with top-line results by year end
Further details on FMX114, including clinical development plans, will be discussed on VYNE’s year end 2020 earnings call at 8:30am ET March 4
BRIDGEWATER, N.J., March 01, 2021 (GLOBE NEWSWIRE) -- VYNE Therapeutics Inc. (Nasdaq: VYNE) (“VYNE” or the “Company”) today announced development plans for FMX114, a fixed combination of pan-JAK inhibitor tofacitinib and sphingosine 1-phosphate receptor modulator fingolimod in a topical gel for the potential treatment of mild-to-moderate atopic dermatitis (AD). FMX114, VYNE’s first product candidate designed to target AD, will be evaluated in a Phase 2a proof of concept study expected to begin in 3Q 2021.
“We are excited to announce VYNE’s newest therapeutic candidate FMX114,” said David Domzalski, Chief Executive Officer of VYNE. “FMX114 is a non-steroidal topical treatment that is designed to address the multi-factorial nature of AD by offering a fixed combination multimodal solution to disease management. Advancement of FMX114 supports our strategic objective of building a diversified pipeline of products to address unmet needs of patients. We look forward to initiating the planned Phase 2a clinical trial in Q3 this year with anticipated top-line results by year end.”
Proof of Concept Demonstrated in an Animal Model of AD
FMX114 was evaluated in a well-known nonclinical model in which dorsal depilated BALB-C mice are dosed with 100µl topical dinitrochlorobenzene (DNCB) solution to induce a type 2 inflammatory response in the skin with AD-like pathology. There was a 32-day induction phase followed by 7 days of both DNCB and investigational drug concomitant treatment. Two doses of FMX114 (0.6% tofacitinib + 0.01% fingolimod and 0.3% tofacitinib + 0.02% fingolimod) were compared with tofacitinib monotherapy, fingolimod monotherapy, triamcinolone (steroid) 0.1%, and DNCB control.

FMX114 Development Timeline
VYNE expects to complete IND-enabling nonclinical safety studies for FMX114 by mid-year 2021. The Company intends to initiate a Phase 2a proof of concept clinical study in the third quarter of this year with top line results anticipated by the end of 2021.
FMX114 is a fixed combination of tofacitinib and fingolimod, formulated as a topical gel. As a pan-JAK inhibitor, tofacitinib inhibits phosphorylation and activation signal transducer and activator of transcription proteins (STATs) that act as primary initiators and propagators of Th2-mediated pro-inflammatory cytokine release in AD.1 Fingolimod, when converted to its phosphate form, inhibits activated inflammatory cells such as dendritic and langerhans cells from migrating between the lymph nodes and other tissues by binding to and modulating the activity of sphingosine 1-phosphate receptors (S1PR).2 Further, S1PR modulation with fingolimod imparts a direct effect on upregulating filaggrin and its byproduct natural moisturizing factor which are critical components in improving skin hydration and overall barrier function.3

About Atopic Dermatitis
Atopic dermatitis (also known as atopic eczema) is a chronic, pruritic inflammatory skin condition that typically affects the face, neck, arms, and legs. Atopic dermatitis can start in early infancy and can persist throughout a patient’s lifetime. It can have a wide-ranging impact on quality of life and there is a substantial burden from direct and indirect costs. Approximately 22 million people are diagnosed and treated for atopic dermatitis in the United States, of whom approximately 19 million are estimated to have mild to moderate disease. The cause of atopic dermatitis is not known but is believed to be due to an interaction between susceptibility genes, the environment, defective skin barrier function, and immunologic responses.
