Treatment of Relapsed T-cell Acute Lymphoblastic Leukemia or T-lymphoblastic Lymphoma With MabCampath

March 16, 2023 updated by: Nicola Goekbuget, Goethe University

German Multicenter Phase II Trial to Study Effectivity and Feasibility of Alemtuzumab (MabCampath®) in T-ALL and T-Lymphoblastic Lymphomas With Minimal Residual Disease (MRD), in Refractory Relapse or in Primary Failure

This study tests the effectivity and tolerability of treatment with alemtuzumab (MabCampath) in patients with relapsed or refractory T-cell acute lymphoblastic leukemia (T-ALL) or T-lymphoblastic lymphoma. In Arm A, patients with refractory relapse receive a 2 week treatment with MabCampath followed by remission evaluation. In case of insufficient response, treatment with cladribine is added. In Arm B, patients with molecular relapse (minimal residual disease) receive a 4 week treatment with MabCampath followed by remission evaluation. In both arms, treatment is continued in case of response for up to two months.
