General information about the trial
|
|||
Main objective of the trial |
1. To explore the antitumor activity of the association of R2-B in terms of complete response (CR) in patients with relapsed/refractory MCL to a first line of therapy.
2. To evaluate the efficacy of a maintenance treatment with Lenalidomide for 18 months from the end of R2-B (from month 7 to 24) for those responding (CR or PR) to the induction, in terms of progression free survival (maPFS).

Protection of trial subjects |
INDUCTION PHASE
Lenalidomide dose modification according to hematological and extrahematological toxicity is allowed. Patients who can not tolerate the dose of 5 mg daily will prosecute the induction phase only with Rituximab and Bendamustine.
If Lenalidomide dosing was halted during the previous cycle and was restarted with a one-level dose reduction without requiring an interruption for the remainder of the cycle, then that reduced dose level will be initiated on day 1 of the new cycle. There will be no more than one dose reduction from one cycle to the next. No dose (re-)escalation is permitted at any time.
Those patients for whom Lenalidomide dose reduction is not sufficient and require also a reduction in the dose of Bendamustine, they will interrupt treatment, they will be considered failure and they will be treated according to the single centre policy. Bendamustine dose reduction is not allowed.
Rituximab dose reduction is not planned.
CONSOLIDATION PHASE
Lenalidomide dose modification according to hematological and extrahematological toxicity is allowed. The minimum dose permitted is 5 mg daily. Patients who can not tolerate this dose will interrupt treatment. If Lenalidomide dosing was halted during the previous cycle and was restarted with a one-level dose reduction without requiring an interruption for the remainder of the cycle, then that reduced dose level will be initiated on day 1 of the new cycle. There will be no more than one dose reduction from one cycle to the next. No dose (re-)escalation is permitted at any time.
Rituximab dose reduction is not planned.
MAINTENANCE PHASE
Permitted lenalidomide dose modifications during the maintenance phase are similar to those in the consolidation phase.

Arm description |
R2-B treatment will be repeated for two cycles every 28 days, then patients will be evaluated for response; in case of CR, PR or SD, they will prosecute treatment for further two cycles. Patients after the end of the induction phase who achieve less than PR will be treated according to best clinical practice but they will be included in the intention-to-treat population. Patients in CR and PR at the end of the induction phase, will continue therapy with a consolidation phase, that includes combination therapy with Lenalidomide and Rituximab (R2) every 28 days for 2 cycles. Patients after the end of the consolidation phase who achieve less than PR will be treated according to best clinical practice but they will be included in the intention-to-treat population. Patients in CR or PR at the end of the consolidation treatment will continue to a maintenance phase with Lenalidomide until disease progression or unacceptable toxicity up to 18 months, with 28-days cycles | ||||||||||||||||
