Spots Global Cancer Trial Database for Topical Sirolimus in Cutaneous Lymphatic Malformations

Study Description

Brief Summary: Cutaneous microcystic lymphatic malformations (CMLMs) are rare conditions of children and adults resulting from abnormal embryologic development of lymphatic vessels. They present as clusters of vesicles full of lymph and blood of various extent. They ooze and bleed, inducing maceration, esthetic impairment, scars, pain, bacterial infections and impaired quality of life. Currently, treatments for CMLMs are disappointing, and their management is challenging. Sirolimus is an inhibitor of mammalian target of rapamycin (mTOR), a serine/threonine protein kinase involved in cell growth and proliferation, cellular metabolism, autophagy and angio-lymphangiogenesis. Topical sirolimus, known to be efficient and well tolerated in cutaneous angiofibromas linked to tuberous sclerosis, has recently been reported effective in few reports of patients with CMLMs. The objective of this trial is to compare the efficacy and safety of a 12-week application of 0.1% topical sirolimus versus topical vehicle in CMLMs in children and adults.

Detailed Description: This blinded multicentre split body randomized controlled phase 2 trial aims to include 50 patients ≥ 6 years old who have a primary CMLM without an underlying malformation. The CMLM will be divided into 2 equal areas of the same severity that will be randomly allocated to 0.1% topical sirolimus or topical vehicle for 12 weeks. During the double-blind 12-week period, both topical products will be applied by a nurse to avoid inter-group contamination and for better compliance. At the end of the 12-week period, the patient/parent will treat the whole area of CMLM with 0.1% topical sirolimus on remaining lesions, for 8 more weeks. Patients will also be seen at week 20 (treatment will be stopped) and at month 12 to evaluate long-term efficacy.
