Official Title

A Phase 2/3, Multi-Center, Double-Blind, Placebo-Controlled, Randomized, Parallel-Group, Dose-Response Comparison of the Efficacy and Safety of a Topical Rapamycin Cream for the Treatment of Facial Angiofibromas (FA) Associated With Tuberous Sclerosis Complex (TSC) in Patients 6 Years of Age and Over


Topical rapamycin has previously been used to treat FA associated with TSC, reducing erythema, papule size, while flattening lesions and improving skin texture. Topical rapamycin has been reported to be well tolerated. The efficacy and safety of a topical rapamycin cream at two strengths (0.5% and 1.0%) will be assessed during a 26 week double-blind treatment phase with assessments made at clinical visits at baseline, 2, 8, 14, 20 and 26 weeks, and at follow-up (4 weeks after the last dose of study drug).
