Clinical Trial Summary

Cantharidin is cited in the dermatology and pediatric literature as a valuable treatment option. Treatment is often available in private practice offices, where a prescribing physician may offer a non-FDA approved treatment on an individualized basis. The situation is different in many hospital and academic settings, such as our own for example, where the formulary is defined through a FDA-approved indication. The absence of an indication precludes its addition to many hospital formularies, thus limiting the options available to a prescribing physician and denying patient access to a treatment offered in the private practice setting. An indication and formulary status require controlled clinical trials on the safety and efficacy of cantharidin in MC. The objective of this trial is to see if this commercially-viable cantharidin formulation has a comparable safety and efficacy profile as formulations previously studied under conditions which most closely match the what has been historically done in the clinic.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Total Lesion Clearance	100% reduction in baseline lesion count	Assessed at each visit, until final visit on week 12
Secondary	Number of Subjects Who Achieve a Clearance of at Least 90% of Their Molluscum Lesions		At study completion, up to 12 weeks
Secondary	Change in the Total Children's Dermatology Life Quality Index Score	Change in the Total Children's Dermatology Life Quality Index (CDLQI) given Visit 1 prior to the first treatment and at the last study visit, up to 12 weeks. The CDLQI examines how the patient feels about the symptoms and treatment, as well as how it affects leisure, school, personal relationships, sleep, clothing choices. A total score is calculated.; The total score for the CDLQI scores range: 0-1 = no effect on child's life 2-6 = small effect 7-12 = moderate effect 13-18 = very large effect 19-30 = extremely large effect	Baseline (At beginning of study, before treatment) and end of study (at study completion, week 12 or at earlier visit if all lesions have cleared)
Secondary	Number of Patients Achieving Complete Lesion Clearance Compared to Prior Study (NCT02665260)	Comparison of the number of subjects achieving complete lesion clearance at study completion (up to 12 weeks) to the same measure obtained in our previous study (NCT02665260)	At study completion, up to 12 weeks
