About the Clinical Study

This is a multi-center phase 2 open label clinical study evaluating the safety and effectiveness QTORIN™  rapamycin 3.9% for the treatment of microcystic lymphatic malformations. Having worked closely with patient advocacy groups to identify the most burdensome symptoms of microcystic lymphatic malformations, the clinical study will determine if QTORIN™ rapamycin 3.9% rapamycin is safe and effective in treating key symptoms of microcystic lymphatic malformations including leaking and bleeding.

About Microcystic Lymphatic Malformations

Microcystic Lymphatic Malformations (Micro LM) is a rare genetic disease of the lymphatic system driven by a genetic defect in the PI3K/AKT/mTOR pathway. Micro LMs often have a cutaneous component and clinically present with lymphorrhea, bleeding, pain, and functional deficits. Infections of malformations can occur and may lead to cellulitis of surrounding tissues or severe, life-threatening infections. While most individuals are diagnosed early in life, the disease can become more pronounced as an individual ages and goes through puberty.

There are no FDA approved treatment for Microcystic Lymphatic Malformations.

About  QTORIN rapamycin 3.9%

QTORIN™ rapamycin 3.9%  is a novel targeted topical formulation of rapamycin , an mTOR inhibitor, being studied for Microcystic Lymphatic Malformations a serious and lifelong genetic disease with no FDA approved therapies.

QTORIN™ rapamycin 3.9% has been awarded both FDA Orphan Drug Designation and Fast Track Designation for its Microcystic Lymphatic Malformations research program.
