[{"type":"text","content":"VYN201 demonstrated positive effect on key biomarkers relevant to vitiligo Data supports VYN201’s rapid onset of action and previously announced positive clinical resultsProgram is on track for Phase 2b initiation in Q2 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. Results from the biomarker analyses include the following: Downregulation of Matrix metalloproteinase-9 (MMP-9) levels: VYN201 induced the downregulation of MMP-9 in biopsied lesional skin after 8 weeks of treatment compared to baseline. MMP-9 is an inflammatory biomarker associated with the detachment and subsequent loss of melanocytes from skin in vitiligo and is elevated in patients with vitiligo. At Week 8, there was a median reduction in MMP-9 of 40.8% in lesional skin compared to baseline for subjects in the 2.0% cohort.Upreg...
