About Mycosis Fungoides

Mycosis fungoides (MF) accounts for almost 50% of all primary cutaneous lymphomas, a form of non-Hodgkin’s lymphoma. The cause of MF remains unknown and there are no curative treatments. MF has an indolent clinical course, slowly progressing from patches to thicker plaques and eventually to tumors over years or decades. Signs include rash, patch and plaques with severe itch. MF typically affects older adults (median age at diagnosis: 55-60 years) with male predominance.


LEDAGA® gel is an alkylating drug indicated for the topical treatment of MF-CTCL in adult patients. LEDAGA® is a gel which is applied topically once a day. The drug has been approved by the European Commission (for the treatment of MF-CTCL in adult patients). Since June 2019, LEDAGA® is commercialized in almost 30 countries including Europe, Canada, Latin America.
