BRIDGEWATER, N.J., Jan. 10, 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 new biomarker data from the previously completed Phase 1b trial in patients with nonsegmental vitiligo. The data show that BET inhibitor, VYN201, had a positive effect on multiple disease-associated biomarkers.
Positive clinical data from the Phase 1b trial were announced in October 2023. The trial was a 16-week open-label study assessing the safety, tolerability, pharmacokinetics, and exploratory efficacy of once-daily topical VYN201 in 29 patients with a clinical diagnosis of active nonsegmental vitiligo, in three dose cohorts (0.5%, 1.0% and 2.0% strengths). Enrolled subjects had two, non-facial active vitiligo lesions. One lesion, selected for treatment with VYN201, had skin tissue biopsies taken prior to first application of VYN201 and after 8 weeks of treatment. Biopsies were analyzed to quantify the effect of VYN201 on specific biomarkers related to inflammation associated with vitiligo, melanocyte proliferation, and melanogenesis. Exploratory data from the 1.0% and 2.0% cohorts showed that VYN201 treatment demonstrated biological activity and a positive effect on certain key biomarkers relevant to vitiligo disease severity and progression. The magnitude of biomarker modulation was more pronounced in the 2.0% dose cohort than in the 1.0% dose cohort, indicative of an emerging dose-response.
