Efficacy and Safety of Chidamide Combined With BEAM Pretreatment Regimen in Autologous Transplantation for T-cell Lymphoma

T cell lymphoma (TCL) is a group of highly heterogeneous aggressive non-Hodgkin lymphomas with different pathogenesis and clinical prognosis. Despite the survival benefits of Anthracycline-based chemotherapy bridging autologous stem cell transplantation (ASCT), 40% to 50% of TCL patients fail to respond to treatment and relapse or die within a short period of time. In 2021, a multicenter, single-arm, open Phase II trial of Chidamide combined with BEAC as a pretreatment regimen for ASCT of high-risk and relapsed/refractory lymphoma was presented at the ASH Meeting (NCT03629873). The results confirmed that Chidamide has a good prospect in ASCT. Chi-BEAC can increase 2Y-PFS from 55% to 93.3% and 2Y-OS from 58% to 94% in TCL patients after ASCT compared with the historical control group, with good tolerance.In order to provide a new program for improving survival rate, this single-center, single-arm clinical study will evaluate the efficacy and safety of Chidamide combined with BEAM Pretreatment Regimen in ASCT treatment of TCL patients.
