Verrica Pharmaceuticals presents results from Phase 3 clinical trials of VP-102

Verrica Pharmaceuticals presented data from the company’s pivotal Phase 3 CAMP-1 and CAMP-2 trials of lead product candidate, VP-102, at the American Academy of Dermatology annual meeting being held in Washington, DC from March 1-5. Both trials of VP-102 in patients with molluscum contagiosum successfully met their primary endpoints. In each trial, a clinically and statistically significant proportion of patients treated with VP-102 demonstrated complete clearance of all treatable molluscum lesions in 12 weeks. On average, molluscum can take approximately 13 months to resolve without treatment, and in some cases can remain unresolved for several years. The two randomized, double-blind, multicenter, placebo-controlled trials evaluated the efficacy of dermal application of VP-102 compared to placebo in subjects with molluscum. In total, the trials enrolled 528 subjects two years of age and older with molluscum at 31 centers in the U.S. Subjects were treated once every 21 days with topical solution of 0.7% cantharidin for up to four applications. Complete clearance of molluscum lesions was evaluated by assessment of the number of lesions at study visits over 12 weeks. Results from CAMP-1 and CAMP-2 showed 46% and 54% of subjects treated with VP-102, respectively, achieved complete clearance of all treatable molluscum lesions at the end of the trials versus 18% and 13% of subjects in the placebo groups. By Day 84, VP-102 treated subjects had a 69% and 83% mean reduction in the number of molluscum lesions, a pre-specified endpoint, in CAMP-1 and CAMP-2 respectively, compared to a 20% increase and a 19% reduction for subjects on placebo. VP-102 was well-tolerated in both trials, with no serious adverse events reported in VP-102 treated subjects. The most frequently reported adverse events were application site reactions that are well-known, reversible side effects related to the mechanism of action of cantharidin, a blistering agent, which is the active ingredient in VP-102. There were no treatment-related serious adverse events reported in CAMP-1 or CAMP-2. Verrica previously announced topline results from both trials on January 3, 2019. Based on the positive results, the company plans to submit a New Drug Application for VP-102 in the second half of 2019. If approved, VP-102 would be the first FDA-approved treatment for molluscum contagiosum.
