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.

Conditions

  • Vascular Malformations
  • Lymphatic Malformation

Interventions

DRUG

Topical 0.1% Sirolimus

The formulation is 0.03 g rapamycin, 1.5 g Transcutol, Quantum Satis (QS) 30g Excipial® hydrocream, corresponding to a concentration at 0.1%. The cream will be packaged in 30 ml aluminium tubes.

DRUG

Topical Vehicle

The same vehicle than the one used in the topical 0.1% sirolimus preparation will be used for the other half area of CMLM, i.e. Excipial® hydrocream. It will be packaged to maintain the double blind way of this trial and will be undistinguishable from the sirolimus cream.
