Genotype-guided Targeted Agents Plus EZH2i for Primary Refractory PTCL

Официальное название

Genotype-guided Targeted Agents in Combination With EZH2 Inhibitor, Zeprumetostat for Primary Refractory Peripheral T-cell Lymphoma (PTCL), a Prospective, Open-label, Multi-center Study

Обзор

To evaluate the safety and efficacy of Zeprumetostat-based combination therapy, selected according to genotyping results, in patients with primary refractory peripheral T-cell lymphoma (PTCL).

Подробное описание

Peripheral T-cell lymphoma (PTCL) is a distinct and heterogeneous histopathologic subtype of non-Hodgkin lymphoma (NHL), accounting for \~10%. Patients with PTCL still have poor treatment response and prognosis under conventional CHOP regimen. Clinical outcomes of refractory patients are even poorer. Targeted drugs are warranted in this group of patients to improve survival. This prospective, multi-center, open-label study will evaluate the efficacy and safety of targeted drug in combination with Zeprumetostat, an EZH2 inhibitor in treatment of primary refractory peripheral peripheral T-cell lymphoma.
