Study of Lenalidomide Maintenance Versus Placebo in Responding Elderly Patients With DLBCL and Treated With R-CHOP

• Status: Completed
• Trial end date: 2019-09-01
• Target enrollment: 0
• Participant gender: All

Summary

This study is designed as a phase III, randomized, double-blind, placebo-controlled trial to explore the effect of maintenance therapy with lenalidomide versus placebo on progression-free survival (PFS) in patients treated with R-CHOP responding to induction therapy

For the primary efficacy variable, PFS, an improvement in median PFS from 38.6 months for Treatment Arm B to 54 months for Treatment Arm A (corresponding to a 2-year PFS of 65% vs 73.6%), is considered clinically relevant.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No
