Combined Immunochemotherapy in Patients With T-Prolymphocytic Leukemia (T-PLL)
|ClinicalTrials.gov Identifier: NCT01186640|
Recruitment Status : Completed
First Posted : August 23, 2010
Last Update Posted : September 26, 2016
|Condition or disease||Intervention/treatment||Phase|
|T-cell-prolymphocytic Leukemia||Drug: Fludarabine, Mitoxantrone, Cyclophosphamide and Alemtuzumab Drug: Alemtuzumab||Phase 2|
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.

Drug: Fludarabine, Mitoxantrone, Cyclophosphamide and Alemtuzumab
I. First treatment phase: Chemoimmunotherapy A-FMC
10 mg s.c., days 1-3
CR: 10 mg s.c., days 1-3 PR/SD: 30 mg s.c., days 1-3 Fludarabine: 20 mg/m2 i.v., days 1-3 Mitoxantrone: 6 mg/m2 i.v., day 1 Cyclophosphamide: 200 mg/m2 i.v., days 1-3 Repeat day 29, maximum 4 cycles.
