• Presentations will highlight positive preclinical and Phase 1b data of novel BET inhibitor, VYN201, in nonsegmental vitiligo

BRIDGEWATER, N.J., May 01, 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 two abstracts reporting results for its novel BET inhibitor, VYN201, have been selected for presentation at the 81st Annual Meeting of the Society for Investigative Dermatology (SID), being held May 15-18, 2024 in Dallas, TX, USA.

“We look forward to sharing our preclinical and Phase 1b data for VYN201 with researchers and clinicians at the upcoming SID Annual Meeting,” said Iain Stuart, Ph.D., Chief Scientific Officer of VYNE. “Our data support the advancement of VYN201 as a differentiated therapy for the potential treatment of nonsegmental vitiligo.”

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.¹ 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 the VYN201 Phase 1b Study in Vitiligo

The Phase 1b trial was a 16-week open-label trial assessing the safety, tolerability, pharmacokinetics, and exploratory efficacy of a once-daily topical formulation of VYN201 in 29 patients with active nonsegmental vitiligo in three dose cohorts (0.5%, 1.0% and 2.0% concentrations). On October 30, 2023, VYNE announced that significant clinical improvement was observed in the 1.0% and 2.0% cohorts, with rapid onset of action and a dose-dependent response. The mean percentage reduction in facial vitiligo area scoring index score from baseline after 16 weeks of treatment was 7.5%, 30.2% and 39.0% for the 0.5%, 1.0% and 2.0% cohorts, respectively. VYN201 was generally well tolerated with no clinically relevant treatment emergent adverse events across all dose cohorts.

About BET Inhibitors

BET proteins play a key role in regulating gene transcription via epigenetic interactions (“reading”), and recent research has determined 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.
