Clinical Trial Summary

This is a phase 2 multi-center, randomized, double-blind, vehicle-controlled ascending dose study to be conducted in non-immunocompromised subjects with molluscum contagiosum.

Description:

This is a phase 2 multi-center, randomized, double-blind, vehicle-controlled ascending dose study to be conducted in up to approximately 192 or 256 non-immunocompromised subjects with molluscum contagiosum. Subjects who satisfy entry criteria will be randomized 3:1 to ascending, sequential dose cohorts of SB206. The highest tolerated dose will also be run in a cohort once daily. Approximately 64 subjects will be randomized to each cohort. Subjects will be treated once daily, twice daily or three times a week for up to 12 weeks. After 30 subjects randomized in a cohort have completed 2 weeks of treatment, the Data Safety Monitoring Board (DSMB) will review the available unblinded safety and tolerability data. The DSMB will determine if the data supports escalating to the next highest dose for the next cohort or if the data shows the dose is not tolerable decreasing to the next lower dose or frequency for the next cohort.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of Subjects Achieving Complete Clearance 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	Proportion of Subjects Achieving Complete Clearance at Each Visit	Proportion of subjects achieving complete clearance of all treated molluscum contagiosum lesions at each visit.	Week 1; Week 2; Week 4; Week 8; Week 12
Secondary	Time to First Complete Clearance	Median time to reach first complete clearance of all molluscum contagiosum lesions (Kaplan-Meier estimate)	Week 12
Secondary	Proportion of Subjects Achieving 75% Reduction at Each Visit	Proportion of subjects achieving 75% reduction from baseline in number of molluscum contagiosum at each visit	Week 1, Week 2, Week 4, Week 8, Week 12
Secondary	Mean Change in Molluscum Contagiosum at Each Visit	Mean change from baseline in number of molluscum contagiosum lesions at each visit	Week 1, Week 2, Week 4, Week 8, Week 12
Secondary	Percent Change in Molluscum Contagiosum at Each Visit	Percent change from baseline in number of molluscum contagiosum lesions at each visit	Week 1, Week 2, Week 4, Week 8, Week 12
