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.

- Negative serum pregnancy test one week prior to treatment (required for female patients before and <2 years after onset of menopause)
- Patient's written informed consent
Exclusion Criteria:
- Clinically significant auto-immune cytopenia or clinically significant hemolytic anaemia with suspicion of immune origin, even if Coombs test is negative
- Active secondary malignancy requiring treatment (except basal cell carcinoma or tumour curatively treated by surgery)
- Medical condition requiring prolonged use of oral corticosteroids (> 1 month)
- Cerebral dysfunction, legal incapacity

- Active infection or severe infection (WHO 4th degree) within the last three months before inclusion to the study
- Participation in any other clinical trial during this study
- Known hypersensitivity to any of the study medications (Fludarabine, Cyclophosphamide, Mitoxantrone or Alemtuzumab)
- Patients who have already received more than 60% of the recommended maximum cumulative dose of an anthracycline (Epirubicine, Adriamycine or Mitoxantrone).
This maximum cumulative dose is defined for the individual substances as follows:

- Patients who received prior treatment with Alemtuzumab alone or in combination with a purine analogue and who did not achieve a PR that lasted at least 6 months
- Patients who are employees of the Sponsor (University of Cologne) or the study sites.
