NCT05618366 | RECRUITING | Lymphoma, Non-Hodgkin

Tazemetostat and Venetoclax in Relapsed/Refractory Non-Hodgkin Lymphoma
Sponsor:

Weill Medical College of Cornell University

Brief Summary:

The goal of this clinical trial is to learn about how a combination of tazemetostat and venetoclax in people with relapsed/refractory Non-Hodgkin Lymphoma (R/R NHL). The main questions that this trial aims to answer are what is the best dose of venetoclax to give with tazemetostat to people with R/R NHL; what types of side effects do people with R/R NHL get when taking venetoclax with tazemetostat; and what effects does this combination have on R/R NHL. Participants will need to take pills by mouth every day and regularly come to the clinic for blood work and imagining to monitor side effects and cancer progression. Participants may receive study drugs for up to 24 months.

Phase

PHASE1

Detailed Description:

This a phase 1, single arm, non-randomized trial of tazemetostat in combination with venetoclax in participants with two types of relapsed/refractory non-Hodgkin lymphoma. The purpose of this study is to evaluate the safety of the combination of tazemetostat and venetoclax in patients with relapsed/refractory (R/R) Follicular Lymphoma (FL) and Diffuse Large B-cell Lymphoma (DLBCL). This trial will be conducted in two parts. To evaluate the safety of the combination of tazemetostat and venetoclax in patients with relapsed/refractory (R/R) Follicular Lymphoma (FL) and Diffuse Large B-cell Lymphoma (DLBCL) we will conduct a phase I trial in two parts. In part one, we will perform a single-arm, open-label sequential dose escalation (3+3) of venetoclax in combination with tazemetostat, given at its recommended phase II dose (RP2D) of 800mg BID, to determine the maximum tolerated dose (MTD) of venetoclax. In part two, we will enroll two expansion cohorts (R/R DLBCL and R/R FL) to further characterize the safety and tolerability of the combination, and to estimate the preliminary efficacy. Up to 18 participants will be enrolled in part 1 and 20 participants will be enrolled in part 2.
