Conditions: Cutaneous T Cell Lymphoma

Details and patient eligibility

About

The main objective of the trial is to investigate whether oral treatment of patients suffering from cutaneous T cell lymphoma with dimethylfumarate is leading to a significant improvement of modified severity assessment tool (mSWAT) values in the skin after 24 weeks of treatment (primary endpoint). Secondary endpoints are dermatologic life quality index, itching and pain measured by a NRS and the blood involvement if applicable.

Primary: safety and efficacy of DMF treatment in CTCL Secondary: Dermatologic Life Quality index, NRS for itching and pain, blood involvement if appl.
