A Phase 3 Molluscum Contagiosum Efficacy and Safety Study

This is a phase 3 multi-center, randomized, double-blind, vehicle-controlled, parallel group study to be conducted in up to approximately 850 subjects 6 months of age and older with molluscum contagiosum (MC). After obtaining informed consent/assent, subjects who satisfy entry criteria will be randomized 1:1 (active:vehicle). Subjects receiving current treatment for MC at the time of the Screening Visit will enter a wash out period of up to 14 days prior to randomization.

Subjects or their caregivers will apply treatment once daily to all lesions identified at Baseline and new lesions that arise during treatment for a minimum of 4 weeks and up to 12 weeks. If the investigator determines all lesions are cleared at a visit, the treatment may stop. If treatment is stopped due to clearance, subjects will continue regularly scheduled visits through Week 24/ET2. Study drug will be dispensed through Week 12/ET1 in case of lesion recurrence between study visits. At each visit subsequent to stopping treatment due to clearance, the investigator will determine if new lesions have occurred since the last visit, and if so, the subject or caregiver will be instructed by the investigator to re-initiate treatment. If the subject or caregiver see new lesions or re-occurrence of lesions in between visits, they should treat these lesions until the next visit. No study drug will be provided after the Week 12 visit. The subject or caregiver will apply study drug to the individual lesions. Periocular lesions will be treated if the lesions are at least 2 cm from the edge of the eye. Subjects will visit the clinic in person at Screening/Baseline, Week 2, Week 4 (unless visit is performed remotely), Week 8, Week 12, and Week 24.

• Have more than one other family member participating in this study (NI-MC304);
• Have at least 1 family member currently participating in a study, other than this study, with a berdazimer containing product (i.e. SB204, SB206, SB208, SB414);
• Have participated in any other trial of an interventional investigational drug or device within 14 days or concurrent participation in another interventional research study;
• History or presence of clinically significant medical, psychiatric, or emotional condition that, in opinion of the investigator, would compromise the safety of the subject or the quality of the data.
