Topical Everolimus in Patients With Tuberous Sclerosis Complex
- Registration Number
- NCT02860494
- Lead Sponsor
- Hospices Civils de Lyon
- Brief Summary
Tuberous sclerosis complex (TSC) is a rare genetic multisystem disorder characterized by the development of hamartomas in several organs (e.g. brain, heart, kidney, liver, lung), and skin in more than 90% of cases. Facial angiofibromas (FA), present in about 80% of patients, are a stigmatizing hallmark of the disease. Everolimus could be a candidate for use as a topical formulation to treat FA. This adaptive seamless Phase II/III study primary objective is to determine the dose of topical everolimus for treatment of FA and evaluate the efficacy and safety of topical everolimus versus placebo in patients with angiofibromas.

Group Intervention Description Topical placebo Placebo Topical placebo will be identical to the everolimus topical formulation. Topical placebo will be applied to the affected areas, once daily, in the evening, for 6 months by the patient or the patient's parents/legal guardians, while observing standardised precautions (avoiding the eyes, washing the hands after application, etc.). Topical everolimus 0.1% Everolimus Everolimus topical formulation will be applied to the affected areas, once daily, in the evening, for 6 months. Dose regimens will be identical, regardless of the dose-strength of the topical formulation. The topical formulation will be applied onto areas of the face affected by FA by the patient or the patient's parents/legal guardians, while observing standardised precautions (avoiding the eyes, washing the hands after application, etc.). Topical everolimus 0.5% Everolimus Everolimus topical formulation will be applied to the affected areas, once daily, in the evening, for 6 months. Dose regimens will be identical, regardless of the dose-strength of the topical formulation. The topical formulation will be applied onto areas of the face affected by FA by the patient or the patient's parents/legal guardians, while observing standardised precautions (avoiding the eyes, washing the hands after application, etc.). Topical everolimus 1% Everolimus Everolimus topical formulation will be applied to the affected areas, once daily, in the evening, for 6 months. Dose regimens will be identical, regardless of the dose-strength of the topical formulation. The topical formulation will be applied onto areas of the face affected by FA by the patient or the patient's parents/legal guardians, while observing standardised precautions (avoiding the eyes, washing the hands after application, etc.).
- Primary Outcome Measures
Name Time Method Facial Angiofibroma Severity Index (FASI) 6 months The FASI is a composite score summing the scores for erythema (0-3), size (0-3) and extension of FA (2:\<50% of the cheek surface; 3:\>50% of the cheek surface). The FASI will be centrally-measured on patient's face photographs by an independent and blinded adjudication committee of 2 dermatologists, with third-dermatologist review for disagreements.
- Secondary Outcome Measures
Name Time Method blood levels of topically applied everolimus 6 months Dermatologist's global assessment of efficacy 6 months using 7-point Likert scale
Dermatological quality of life 6 months using DLQI (Dermatology Life Quality Index) for adults, CDLQI (Children's Dermatology Life Quality Index) for children
FA size 6 months FA size (in millimetres) of the 3 largest targeted FA papules previously identified by the investigator
Patient or parents self-assessment 6 months using 7-point Likert scale
Local tolerance of the topically applied formulation using patient self-assessment 6 months dryness score 6 months assessed by physicians
scaling scores 6 months assessed by physicians
