Study of Tazemetostat in Newly Diagnosed Diffuse Large B Cell and Follicular Lymphoma Patients Treated by Chemiotherapy

Registration Number
NCT02889523
Lead Sponsor
The Lymphoma Academic Research Organisation
Brief Summary

Phase I of the study is designed to determine the recommended phase II dose (RP2D) for tazemetostat in patients treated with 8 cycles of R-CHOP 21.

Phase II of the study is designed to determine the safety and the efficacy of tazemetostat in DLBCL and FL patients :
...

Detailed Description

Phase I:

Up to 18 patients will be recruited, using a conventional dose-escalation algorithm (3+3 patients per dose level) to identify the maximum tolerated dose (MTD) which will be deemed the RP2D. Patients will receive 8 cycles of RCHOP every 21 days and tazemetostat every day, starting on day 2 of cycle 1.
