A Phase 3 Efficacy & Safety of SB206 & Vehicle Gel for the Treatment of MC (B-SIMPLE2)

A Phase 3 Multi-Center, Randomized, Double-Blind, Vehicle-Controlled, Parallel Group Study Comparing the Efficacy and Safety of SB206 and Vehicle Gel Once Daily in the Treatment of Molluscum Contagiosum

This is a Phase 3 multi-center, randomized, double-blind, vehicle-controlled, parallel group study to be conducted in up to approximately 340 subjects ≥6 months of age with MC. Subjects or their caregivers will apply SB206 12% or Vehicle Gel once daily for a minimum of 4 weeks and up to 12 weeks to all lesions identified at Baseline and new treatable lesions that arise during the course of the study.

Study Overview

• Status: Completed
• Conditions: Molluscum Contagiosum
• Intervention / Treatment: Drug: SB206 12%; Drug: Placebo

Detailed Description

This is a Phase 3 multi-center, randomized, double-blind, vehicle-controlled, parallel group study to be conducted in approximately 340 subjects with MC. After obtaining informed consent/assent, subjects who satisfy entry criteria will be randomized 2:1 (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 SB206 12% or Vehicle Gel once daily for a minimum of 4 weeks and up to 12 weeks to all lesions identified at Baseline and new treatable lesions that arise during the course of the study. Subjects or their caregivers will continue to treat the area until the next scheduled visit even if the lesion(s) clear. If the investigator determines all lesions are cleared at a clinic visit, the treatment may stop. Subjects will visit the clinic at Screening/Baseline, Week 2, Week 4, Week 8, Week 12. In addition, subjects will be seen in the clinic for a safety follow-up at Week 24.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Complete Clearance of All Treatable MC at Week 12	Percent (proportion) of subjects with complete clearance of all treatable MC at Week 12. This was measured by dividing the number of subjects who showed complete clearance by the number in that treatment group (this represents our primary outcome variable).	12 Weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Complete Clearance of All Treatable MC at Week 8	Percent (proportion) of subjects with complete clearance of all treatable MC at Week 8. This was measured by dividing the number of subjects who showed complete clearance at week 8 by the number in that treatment group (this represents our secondary outcome variable).	8 Weeks
