About

The purpose of this study is to compare the efficacy of R2-miniCHOP (Sub-cutaneous Rituximab-miniCHOP + lenalidomide) and R-miniCHOP (Sub-cutaneous Rituximab-miniCHOP) in patients aged 80 years old or more with not previously treated cluster of differentiation antigen 20 positive (CD20+) diffuse large B-cell lymphoma as measured by the overall survival (OS).The SENIOR trial will evaluate the tolerance and efficacy of the combination of the R2-miniCHOP regimen and compare this experimental arm to the standard R-miniCHOP regimen.The statistical plan is based on the hypothesis of an increase by 15% of the 2y-OS in favor of the experimental arm, as compared to the reference arm (R-miniCHOP).

Full description

The purpose of this study is to compare the efficacy of R2-miniCHOP (Sub-cutaneous Rituximab-miniCHOP + lenalidomide) and R-miniCHOP (Sub-cutaneous Rituximab-miniCHOP) in patients aged 80 years old or more with not previously treated cluster of differentiation antigen 20 positive (CD20+) diffuse large B-cell lymphoma as measured by the overall survival (OS).

Primary endpoint of the study is to compare the efficacy of R2-miniCHOP (Sub-cutaneous Rituximab-miniCHOP + lenalidomide) and R-miniCHOP ((Sub-cutaneous Rituximab-miniCHOP) in patients of 80 years old or more with not previously treated CD20+ diffuse large B-cell lymphoma as measured by the overall survival (OS).

Secondary endpoints are:

• To evaluate the efficacy and the safety of R2-miniCHOP as measured by the PFS (Progression Free Survival), EFS (Event Free Survival), the DoR (duration of response), the DFS (disease free survival), response rate at the end of the treatment, the additional toxicities
• To evaluate the simplified scale prognostic impact (IADL, MNA, G8, CIRS-G)
• To assess the quality of life before and after treatment This study is a multicentric, phase III, open-label, randomized (1:1) trial evaluating the efficacy of R2-miniCHOP in patients aged of 80 years or more with non-previously treated CD20+ diffuse large B-cell lymphoma (age-adjusted IPI= 0 to 3), Ann Arbor stage II to IV with a performance status ECOG from 0 to 2.

This study includes a run in phase to assess feasibility, safety and tolerance of subcutaneous rituximab injections and oral lenalidomide (10 mg D1-D14) in combination with dose-reduced intensity CHOP regimen.

Enrollment: 250 patients
