Trial will evaluate once-daily VYN201 gel in subjects with either active or stable nonsegmental vitiligo
Top-line data from the 24-week double-blind portion of the trial expected in mid-2025
BRIDGEWATER, N.J., June 05, 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 subject has been dosed in a Phase 2b trial evaluating VYN201 in subjects with either active or stable nonsegmental vitiligo. VYN201 is a novel pan-bromodomain and extra-terminal domain (BET) inhibitor designed for local administration. Top-line data from the 24-week vehicle-controlled treatment period are expected in mid-2025.
The randomized, double-blind, vehicle-controlled trial will evaluate the safety and efficacy of once-daily VYN201 topical gel in three dose cohorts (1%, 2% and 3% concentrations) compared to vehicle for 24 weeks. A total of approximately 160 subjects will be randomized at a 1:1:1:1 ratio. Following the 24-week treatment period, subjects in the active treatment arms will continue for an additional 28 weeks, and subjects in the vehicle group will be equally re-randomized to receive VYN201 1%, 2% or 3% gel for an additional 28 weeks. The primary efficacy endpoint of the trial is the proportion of subjects achieving an improvement in Facial Vitiligo Area Scoring Index of at least 50% from baseline (F-VASI50) at week 24 compared to vehicle, with additional secondary endpoints of F-VASI and Total VASI (T-VASI) at weeks 24 and 52.
“Dosing the first subject in the Phase 2b trial for vitiligo is an important milestone for the VYN201 program and our Company,” said David Domzalski, President and CEO of VYNE. “In our prior Phase 1b trial, VYN201 demonstrated a significant clinical response with a rapid onset of action and a favorable safety and tolerability profile, including low systemic exposure. We believe that VYN201 has the potential to become a valuable and differentiated therapy for patients with vitiligo. We look forward to reporting top-line data from the 24-week treatment period in mid-2025.”
About Vitiligo
Vitiligo is a chronic autoimmune depigmenting disorder of the skin, characterized by the loss of pigment producing cells known as melanocytes. Vitiligo is the most common depigmenting skin condition, with a prevalence estimated at 0.5-2.0% of the world population. There is currently only one FDA-approved product for the treatment of vitiligo. Nonsegmental vitiligo is the most common type of vitiligo.
About VYN201
VYN201 is a pan-bromodomain BET inhibitor designed to be locally administered as a “soft” drug to address diseases involving multiple, diverse inflammatory cell signaling pathways, while providing low systemic exposure. In addition to demonstrating clinical proof-of-concept in vitiligo, VYN201 has produced consistent reductions in pro-inflammatory and disease-related biomarkers and improvements in disease severity in several preclinical models (using several different routes of administration).
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.
