maintenance with Alemtuzumab following a induction with combined immunochemotherapy consisting of Fludarabine, cyclophosphamide, mitoxantrone and alemtuzumab

Other Name: Mabcampath

Detailed Description:

As the median survival time of patients with T-PLL is less than 12 months, the treatment of T-PLL is a special challenge.

The overall response rates with conventional chemotherapy or Deoxycoformycin were low (about 30% and 40%), with the monoclonal antibody Alemtuzumab response rates of 50% to 70% were achieved, but the duration of the response was short.

In the previous trial (T PLL 1), the efficacy of the FMC regimen (FMC = Fludarabine, Mitoxantrone and Cyclophosphamide) was tested, a preliminary analysis of 16 patients revealed a response rate of more than 60% after FMC-polychemotherapy and 83% after the subsequent administration of Alemtuzumab.

The goal of the T-PLL2-protocol is to assess if the simultaneous administration of FMC-polychemotherapy and Alemtuzumab with a subsequent Alemtuzumab maintenance therapy is capable of improving the remission rate and the disease-free survival time in patients with T-PLL.
