VYN202 has been designed to achieve class-leading potency and BD2-selectivity

Trial will evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of VYN202 in healthy volunteers; top-line data expected in 2H’24

BRIDGEWATER, N.J., June 13, 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 that the first healthy volunteers have been dosed in the Phase 1a trial of VYN202. VYN202 is an oral small molecule BD2-selective bromodomain and extra-terminal domain (BET) inhibitor that is being developed for the treatment of immuno-inflammatory diseases. Top-line data are expected in the second half of 2024.

“We are pleased to announce the initiation of the first-in-human clinical trial of VYN202, a highly selective and potent orally administered BET inhibitor. In preclinical testing, VYN202 achieved consistent improvements in disease severity across a variety of inflammatory and fibrotic models as well as reductions in pro-inflammatory and disease-related biomarkers,” said David Domzalski, President and CEO of VYNE. “We believe VYN202 has significant potential as a treatment option for a broad range of immune-mediated diseases, and we look forward to reporting top-line data from the Phase 1a trial in the second half of this year.”

The Phase 1a trial is a first-in-human double-blind, placebo-controlled study in healthy volunteers and consists of single ascending dose (SAD) and multiple ascending dose (MAD) components. The trial is currently 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.

“Early generation BET inhibitors show similar affinity to both BD1 and BD2 bromodomains of BET proteins that has been implicated in both gastrointestinal and hematologic dose limiting toxicities,” said Dr. Iain Stuart, Chief Scientific Officer of VYNE. “We believe VYN202’s high potency and selectivity towards the BD2 bromodomain of BET proteins may result in an improved benefit-risk profile when treating immuno-inflammatory diseases. Following highly encouraging preclinical data, we are eager to evaluate the clinical safety, tolerability, pharmacokinetics and pharmacodynamics of VYN202 to further inform our future clinical development plans.”

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.
