Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, multicenter, open label, non-randomized, phase I/II-study to define safety and efficacy of BRL combination in relapsed/refractory patients and to recommend a safe and efficacious dose for future phase II/III study.

Hypothesis: The simultaneous administration of BRL in relapsed CLL is feasible, safe and efficient.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

As too its mechanism of action lenalidomide seems to work rather by immunomodulation than by a direct anti-proliferative activity against CLL cells. Lenalidomide stimulates T- and NK-cells, modulates the tumour microenvironment in CLL and inhibits bone marrow angiogenesis. There is a rationale to combine lenalidomide with the alpha-CD20 mAb rituximab because lenalidomide enhances NK cell mediated antibody dependent cytotoxicity of rituximab treated NHL cells. On the other hand, there is increasing evidence that the combination of chemotherapy (FC) and rituximab results in highest response rates and longest progression-free survival in treatment naive and relapsed CLL. Besides FCR the combination of bendamustine, a hybrid alkylating agent with properties of a purine-analogue, with rituximab (BR) seems to be very active in relapsed and treatment-naive CLL based on results of a phase II trial of the GCLLSG. Preliminary results with lenalidomide showed a promising response rate of 32% including high risk patients. Thus, the combination of BRL could improve the therapeutic activity in high risk CLL by combining two immunomodulatory with a classic cytotoxic principle.
