ClinicalTrials.gov Identifier: NCT03826628

Brief Summary:
The study aims to compare the safety and efficacy of two different strengths of Rapamycin cream, topical and placebo over 26 weeks in the treatment of facial angiofibroma (FA) associated with Tuberous Sclerosis Complex (TSC).

Condition or disease Intervention/treatment Phase
Facial Angiofibroma Tuberous Sclerosis Drug: rapamycin Drug: placebo Phase 2 Phase 3

Detailed Description:

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).

Primary Outcome Measures :
  1. Percentage of participants obtaining successful treatment [ Time Frame: After 26 weeks treatment ]
    Success on the Investigator Global Assessment (IGA) scale is defined as clear or almost clear with an improvement of at least two grades from baseline


Secondary Outcome Measures :
  1. Time to treatment success [ Time Frame: From first dose to 26 weeks ]
    The time elapsed from the first dose to the time of treatment success, according to the IGA scale

  2. Change from baseline in IGA [ Time Frame: At baseline and after 26 weeks treatment ]
    The change in grading on the IGA scale from baseline

  3. Change from baseline in FASI [ Time Frame: At baseline and after 26 weeks treatment ]
    The change in grading on the Facial Angiofibroma Severity Index (FASI) from baseline

  4. Subjective (participant or parent/caregiver) improvement rating [ Time Frame: After 26 weeks treatment ]
    Percentage improvement in FA since beginning treatment, as assessed by the participant or parent/caregiver

  5. Objective (clinician) improvement rating [ Time Frame: After 26 weeks treatment ]
    Percentage improvement in FA since beginning treatment, as assessed by the clinician

  6. Categorical Change in FA [ Time Frame: After 26 weeks treatment ]
    Change in FA since beginning treatment on a 5-point scale, as assessed by the participant or parent/caregiver
