Announcement
VYNE Therapeutics Inc. announced topline results from its Phase 2b trial evaluating Repibresib gel in nonsegmental vitiligo.
AI Summary
VYNE Therapeutics announced topline results from its Phase 2b trial of Repibresib gel in nonsegmental vitiligo, a condition that causes loss of skin color. The study involved 177 subjects and compared three daily doses (1%, 2%, 3%) to a vehicle gel across 45 sites in North America.
The trial did not meet its main goal of at least 50% improvement in the Facial Vitiligo Area Scoring Index (F-VASI50) or the key secondary goal of 75% improvement (F-VASI75) by week 24. However, the highest 3% dose achieved a 43.6% reduction in facial vitiligo severity versus 25.6% for vehicle and a 28.3% drop in total body score (T-VASI) versus 16.2% for vehicle, both nominally significant.
VYNE noted an unusually strong vehicle effect and higher dropout rates in active arms. The company will end the trial’s extension phase and seek an outside partner to continue developing Repibresib.

Announcement
VYNE Therapeutics Inc today provided a program update for VYN202 following the clinical hold issued by the U.S. Food and Drug Administration (FDA) in April for the Company's Phase 1b clinical trial in the treatment of moderate-to-severe plaque psoriasis.
AI Summary
VYNE Therapeutics Inc. provided an update on its VYN202 program, an oral small molecule BET inhibitor for treating moderate-to-severe plaque psoriasis. The FDA had placed a clinical hold on the Phase 1b trial in April due to testicular toxicity observed in dogs during non-clinical studies. The hold has now been partially lifted, allowing female patients to continue receiving the lower doses of 0.25 mg and 0.5 mg, while the 1 mg dose is suspended because of its lower toxicological safety margin. For male patients, the trial remains on hold until additional data from a 12-week toxicology study in dogs is provided and reviewed. In response, the Company has unblinded the data from the ongoing trial and has decided to stop enrolling additional psoriasis patients as it refocuses VYN202’s development towards other serious immune-mediated diseases.

VYNE Therapeutics Inc announced positive results from the multiple ascending dose ("MAD") portion of its Phase 1a SAD/MAD trial of VYN202.
AI Summary
VYNE Therapeutics Inc. announced positive results from the multiple ascending dose (MAD) portion of its Phase 1a SAD/MAD trial of VYN202. In this trial, healthy volunteers received daily doses of VYN202 for 14 days. The data showed that VYN202 has a good safety profile with no serious or drug-related adverse events, eliminating issues like thrombocytopenia seen with earlier BET inhibitors. The drug reached steady-state levels after seven doses and maintained effective blood concentrations throughout a 24-hour period, supporting its once-daily dosing. It also demonstrated robust effects by engaging its target marker and significantly reducing inflammatory biomarkers associated with immune-mediated disorders. These promising results suggest that VYN202 may offer a new, convenient treatment option for various immune and inflammatory conditions, paving the way for further clinical trials to assess its long-term benefits.

VYNE Therapeutics Inc. announced positive data from the single ascending dose ("SAD") portion of its ongoing Phase 1a trial of VYN202.
AI Summary
VYNE Therapeutics Inc. announced positive results from the single ascending dose (SAD) portion of its ongoing Phase 1a trial for VYN202. In this study, VYN202 was found to be generally well tolerated in healthy volunteers, with no drug-related adverse events reported across all dose groups. The pharmacokinetic data showed that VYN202’s exposure in blood increased in a dose-dependent manner, meeting expectations for plasma and urine concentrations. Additionally, the pharmacodynamic activity was promising, as blood tests revealed increased levels of the marker protein HEXIM1, indicating successful target engagement with BET proteins, and showed an inhibitory effect on certain inflammatory biomarkers related to conditions like psoriasis and rheumatoid arthritis. The trial has now progressed to the multiple ascending dose (MAD) portion, with further results anticipated in Q4 2024.
