EZH2 inhibitors enhance T cell-based immunotherapies, improving lymphoma treatment by reversing immunosuppression and boosting CAR-T cell efficacy, with promising preclinical results leading to ongoing clinical trials.
EZH2 inhibitors may enhance cancer immunotherapies, according to a Weill Cornell Medicine study. Combining T-cell-based immunotherapy with EZH2 inhibition was more effective at shrinking B-cell non-Hodgkin lymphomas (B-NHL) than immunotherapy alone. Pilot studies are underway to test this approach in lymphoma patients.
Valemetostat, a dual EZH1/EZH2 inhibitor, showed activity in relapsed/refractory peripheral T-cell lymphoma (PTCL) patients, with 44% objective response and manageable safety profile, in a phase II trial (VALENTINE-PTCL01).
