The primary objective of the study is to determine the presence or absence of systemic cantharidin exposure from a single 24-hour dermal application of VP-102 topical film-forming solution [0.7% (w/v) cantharidin] (VP-102) when applied to molluscum contagiosum (molluscum) lesions on pediatric subjects 2 years old and older. Treatment will continue over the course of 3 additional 21 day intervals allowing for further evaluation of safety, efficacy and impact on quality of life.
