Primary Outcome Measures
NameTimeMethod
Main Objective: The primary objective of this phase II study is to assess the efficacy of lenalidomide in combination with rituximab in relapsed/refractory PCNSL as measured by the objective response rate (CR + Cru + PR) at the end of the 8 cycles of induction therapy. Therapeutic responses will be evaluated according to the IPCG recommendations;Secondary Objective: -Tolerance and toxicity<br>-Duration of response<br>-PFS at one year<br>-Overall survival<br>-Quality of life<br>;Primary end point(s): Objective response rate (CR + CRu + PR) at the end of the induction treatment according to the international study group for PCNSL (IPCG) criteria.<br>;Timepoint(s) of evaluation of this end point: At the end of the induction treatment (nine months)
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): -The safety of the association during induction and maintenance therapy in a population of PCNSL (NCI V4)<br>-The duration of response<br>-PFS at one year from the date of inclusion to the date of progression of the disease or death<br>-OS from the date of inclusion to the date of death<br>-Quality of life using QLQ-C30 EORTC;Timepoint(s) of evaluation of this end point: -Tolerance and toxicity during induction and maintenance therapy<br>-Duration of response<br>-PFS at one year<br>-Overall survival (date of death)<br>-Quality of life at the end of induction and maintenance therapy<br>
