VYNE Therapeutics Announces FDA Clearance of IND Application for VYN202, a Novel BD2-Selective BET Inhibitor

In preclinical studies, VYN202 achieved consistent reductions in pro-inflammatory and disease-related biomarkers and improvements in disease severity across a variety of inflammatory and fibrotic models

Phase 1a SAD/MAD trial expected to start this quarter

BRIDGEWATER, N.J., May 06, 2024 (GLOBE NEWSWIRE) -- VYNE Therapeutics Inc. (Nasdaq: VYNE) (“VYNE” or the “Company”), a clinical-stage biopharmaceutical company developing proprietary, innovative and differentiated therapies for the treatment of immuno-inflammatory conditions, today announced the clearance of its Investigational New Drug application (“IND”) by the U.S. Food and Drug Administration for VYN202, an oral BD2-selective BET inhibitor. VYNE plans to initiate a first-in-human Phase 1a single ascending dose/multiple ascending dose (“SAD/MAD”) trial in healthy volunteers this quarter and expects to report top line results from the SAD/MAD trial in the second half of this year.

“VYN202 is a highly selective and potent orally administered BET inhibitor that we believe has significant potential as a treatment option for autoimmune diseases. Clearance of the IND for VYN202 marks a major step forward in this effort,” said David Domzalski, President and CEO of VYNE. “We look forward to initiating the Phase 1a trial in the coming weeks to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of VYN202.”

The VYN202 Phase 1a trial is a double-blind, placebo-controlled study in healthy volunteers and consists of SAD and MAD components. The study is expected to enroll approximately 64 healthy adult subjects into five SAD and three MAD cohorts to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of VYN202. If the Phase 1a portion of the trial is successfully completed, VYNE plans to initiate Phase 1b trials in subjects with moderate-to-severe plaque psoriasis and moderate-to-severe adult-onset rheumatoid arthritis, with top line results anticipated in the second half of 2025.

About VYN202

VYN202 is an innovative, oral small molecule BD2-selective BET inhibitor that has been designed to achieve class-leading selectivity (BD2 vs. BD1), maximum potency versus BD2 and optimal oral bioavailability. By maximizing BD2 selectivity, VYNE believes 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, in which the damaging effects of unrestricted inflammatory signaling activity is common. VYN202 is structurally distinct from VYNE’s pan-BET inhibitor (VYN201) and covered by distinct PCT and provisional composition of matter patent applications directed to new chemical entities and their uses.

About BET Inhibitors

BET proteins play a key role in regulating gene transcription via epigenetic interactions (“reading”), and recent research has identified a key role for these proteins in regulating B cell and T cell activation and subsequent inflammatory processes. As epigenetic readers, BET proteins regulate the recruitment of transcriptional factors that are key to the production of several pro-inflammatory cytokines. BET inhibitors have the potential to treat a range of immuno-inflammatory and fibrotic diseases by blocking pro-inflammatory cytokine transcription with additional potential in myeloproliferative neoplastic disorders.

About VYNE Therapeutics Inc.

VYNE’s mission is to improve the lives of patients by developing proprietary, innovative and differentiated therapies for the treatment of immuno-inflammatory conditions. The Company’s unique and proprietary bromodomain & extra-terminal (BET) domain inhibitors, which comprise its InhiBET™ platform, include a locally administered pan-BD BET inhibitor (VYN201) and an orally available BD2-selective BET inhibitor (VYN202) that were licensed from Tay Therapeutics Limited.
