简要总结
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.
详细描述
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.

结局指标
主要结局
Proportion of Subjects Achieving Complete Clearance at Week 12
时间窗: 12 weeks
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).
次要结局
- Proportion of Subjects Achieving Complete Clearance at Each Visit(Week 1; Week 2; Week 4; Week 8; Week 12)
- Time to First Complete Clearance(Week 12)
- Proportion of Subjects Achieving 75% Reduction at Each Visit(Week 1, Week 2, Week 4, Week 8, Week 12)
- Mean Change in Molluscum Contagiosum at Each Visit(Week 1, Week 2, Week 4, Week 8, Week 12)
- Percent Change in Molluscum Contagiosum at Each Visit(Week 1, Week 2, Week 4, Week 8, Week 12)
