Vyome Therapeutics Achieves Positive Results in Phase 2 Trial of VB-1953

June 17, 2020

Catawba Research is proud to have served as the CRO for Vyome Therapeutics on their successful Phase 2 Trial of VB-1953 for Moderate to Severe Acne. Needless to say, Catawba Research is excited for our client and honored to be by their side.

Vyome Therapeutics is a clinical-stage company developing locally-acting, next generation therapeutics for immuno-inflammatory diseases. The group recently announced positive data from its Phase 2 trial of VB-1953, a first-in-class topical bactericidal and TLR-MD2 inhibitor being developed for the treatment of moderate to severe inflammatory facial acne vulgaris.

Catawba Research CEO, Zaidoon Al-Zubaidy, shared his excitement in seeing Vyome meet this amazing milestone.  “When our Sponsors succeed, we do, too.  I couldn’t be prouder of our team behind the trial and of our relationship with Vyome Therapeutics.  We look forward to working with them in the future and continue to support them in moving this valuable product to market.”

Results from the trial demonstrated a statistically significant difference in the primary endpoint, the mean absolute change in inflammatory lesions at week 12, for VB 1953 when applied once a day (QD) vs. combined vehicle group (p <0.012). In the comparison between the VB-1953 QD arm versus vehicle QD, the mean absolute change in the inflammatory lesions at week 12 in the intent to treat (ITT) group showed 20.4 and 17.8 respectively, with p<0.003, and 20.4 and 16.6 respectively in per protocol group with p<0.001. In addition, VB-1953 exhibited an excellent safety profile and there were no drug related adverse or serious adverse events.

“These results demonstrate that VB-1953, with its dual mechanism of action directly killing resistant and non-resistant C. acnes strains while blocking inflammation through TLR-MD2 inhibition, has the potential to become a safe and effective topical treatment for facial acne and an alternative to oral, systemic drugs,” Dr. Shiladitya Sengupta, Scientific Co-Founder of Vyome, said in a press release issued by the company.

The Phase 2 randomized, multicenter, double-blind, dose-ranging study was designed to evaluate the safety and efficacy of VB-1953 topical gel when applied once daily and twice daily for 12 weeks in subjects with moderate to severe inflammatory facial acne vulgaris. Vyome enrolled 471 patients across 13 trial sites in the U.S.  Once daily application was found to be as effective as twice daily application in the mean absolute change in the inflammatory lesions.

In the press release, Venkat Nelabhotla, Chief Executive Officer of Vyome Therapeutics, added, “We are very pleased to have met the primary endpoint of the study, and to demonstrate the continued safety of the molecule. Patients need a highly effective drug, and our data shows a very high response, which is encouraging as we plan to advance to Phase 3 with a once daily dose. We look forward to delivering a next-generation solution to patients.”

Although the study was not powered to test for significance in secondary end points, the drug (VB-1953 QD group) achieved a 66.6% mean reduction in inflammatory lesions at week 12 with p<0.020 in ITT and p<0.004 per protocol group versus vehicle group, and a 49.6% successful improvement in the IGA score (minimum two-grade improvement and achieving clear or almost clear IGA score at week 12) with p<0.361 in ITT group and p<0.069 per protocol group versus vehicle group.  

About VB-1953
Vyome’s lead clinical drug candidate, VB-1953, is a first-in-class, topical, bactericidal small molecule with a novel mechanism of action in acne. VB-1953 reduces inflammatory lesions in C. acnes by blocking inflammatory cytokine production through TLR-MD2 inhibition and has demonstrated the ability to treat antibiotic-resistant C. acnes strains. VB-1953 is the first bactericidal drug candidate to be tested for the treatment of C. acnes. VB-1953 is delivered topically with a microtechnology gel system that ensures the drug is retained at the site of infection and minimizes systemic exposure. Acne caused by antibacterial-resistant C.acnes currently poses an emerging and unmet need for patients worldwide, with a potential $2B market opportunity in the US alone.
