Trial or other data

Sep 20In two identical PIII trials (CAMP-1 and CAMP-2; n=582), topical application of cantharidin, an extract from blister beetles, every 21 days for a maximum of 4 treatments resulted in higher rates of complete lesion clearance compared to vehicle (46.3% vs. 18% and 54.0% vs. 13%, respectively) [5].
Mar 19Further data from CAMP-1 and CAMP-2 trials in 528 pts with MC. Pts were treated once every 3 weeks for up to a total of 12 weeks with VP-102 (a topical treatment containing a solution of 0.7% cantharidin in a single-use applicator). By the end of the study, 46% of treated pts in CAMP-1 and 54% of treated pts in CAMP-2 had complete clearance of all treatable molluscum lesionsvs. placebo; 18% and 13%, respectively. VP-102 performed similarly in the mean reduction of the number of lesions: 69% and 83% reduction in CAMP-1 and CAMP-2. Placebo patients in CAMP-1 had a 20% increase in lesions, while those in CAMP-2 had a 19% reduction.[2,3]
Jan 19PII Innovate open-label trial (VP-102-103; NCT03186378) that evaluated the safety, efficacy and systemic exposure of VP 102 completed in 33 children. with MC in the US.
Jan 19Topline data from the phase III CAMP-1 and CAMP-2 trials showed complete clearance of of all treatable molluscum lesions at day 84 when treated with VP 102 vs. 18% and 13% of pts in the placebo groups (p < 0.0001). Pts treated with VP 102 had a 69% and 83% mean reduction in the number of molluscum lesions, in CAMP-1 and CAMP-2 trials, respectively vs. 20% and 19% for pts on placebo. In these trials, VP 102 was generally safe and well-tolerated, with mild to moderate side-effects which were; application site vesicles, pain , pruritus, erythema, scab, discolouration and dryness. No treatment-related serious adverse events were observed.[2]
Sep 18Positive safety and efficacy results announced from PII Innovate open-label trial (VP-102-103; NCT03186378). A median reduction in molluscum lesions of 98% vs. baseline across all patients were observed, and 50% of pts who completed the trial showed complete clearance of their treatable molluscum lesions, at the end of week 12.[2]
Mar 18A double-blind, parallel, prospective, randomised PIII trial is initiated to evaluate the safety and efficacy of VP 102 in pts with molluscum contagiosum (CAMP-1, NCT03377790). The trial recruited 266 pts in the US.[2]
Feb 18PIII CAMP-2 double-blind, parallel, prospective, randomised trial (NCT03377803; VP102-102) initiated to evaluate the safety and efficacy of VP 102 in pts with MC. The trial recruited 262 pts in the US.[2]
