VYNE Therapeutics announced positive results from the multiple ascending dose (MAD) portion of its Phase 1a trial for VYN202, a novel BD2-selective BET inhibitor. The study demonstrated a favorable safety and tolerability profilewith no serious adverse events or drug-related issues historically associated with earlier BET inhibitors.
Key findings include: favorable pharmacokinetics supporting once-daily dosing, dose-dependent exposure reaching steady state after 7 doses, and robust pharmacodynamic activity. The drug showed no interaction with methotrexate and demonstrated dose-dependent increases in target engagement biomarker HEXIM-11, with maximal effect at 0.5mg to 1.0 mg QD. VYN202 also inhibited multiple inflammatory biomarkers related to Th17 and Th1/myeloid activity.
