BRIDGEWATER, N.J., Sept. 12, 2024 (GLOBE NEWSWIRE) -- VYNE Therapeutics Inc. (Nasdaq: VYNE) (“VYNE” or the “Company”), a clinical-stage biopharmaceutical company focused on developing differentiated therapies to treat chronic inflammatory and immune-mediated conditions with high unmet need, today announced positive data from the single ascending dose (“SAD”) portion of its ongoing Phase 1a trial of VYN202. The Phase 1a trial is a two-part, double-blind, placebo-controlled dose-escalation study in healthy volunteers consisting of SAD and multiple ascending dose (“MAD”) components to evaluate the safety, tolerability, pharmacokinetics (“PK”) and pharmacodynamics of VYN202. Findings from the SAD portion of the Phase 1a trial to date are as follows:

VYN202 Was Generally Well Tolerated Across All Dose Groups

Single ascending doses of VYN202 across all cohorts were generally well tolerated up to and including the highest planned dose level. There were no serious adverse events, drug-related adverse events, or clinically significant abnormalities in clinical laboratory results or electrocardiogram findings.

VYN202 Demonstrated Dose-Dependent PK

VYN202 also met expected PK parameters, with plasma and urine drug concentrations of VYN202 increasing in a dose-dependent manner across all doses tested.

VYN202 Demonstrated Pharmacodynamic Effects

Participant blood samples were stimulated ex-vivo to assess the pharmacodynamic impact of single doses of VYN202 on key target-engagement and inflammatory biomarkers. Results demonstrated an increase in marker protein HEXIM1, indicative of target engagement of VYN202 with BET proteins1. Additionally, exploratory data from the SAD arm showed that single doses of VYN202 demonstrated biological activity and an inhibitory effect on select inflammatory biomarkers relevant to psoriasis and rheumatoid arthritis.

Phase 1a MAD Portion of Trial Initiated

The primary objectives of the MAD portion of the Phase 1a trial are to assess safety, tolerability, PK and pharmacodynamics of VYN202 over 14 days at different dose levels. Results are expected in Q4 2024.

“These results from our SAD trial mark the first clinical data for our BD2-selective BET inhibitor, VYN202, and represent an important milestone for our Company and the development of our BET inhibitor platform,” said David Domzalski, President and Chief Executive Officer of VYNE. “We look forward to further assessing safety and PK as well as VYN202’s potential to impact several relevant biomarkers following multiple doses, which we expect to disclose next quarter. These data would inform the design of our planned studies in psoriasis and rheumatoid arthritis.”
