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

Phase 2

Recruiting

• Conditions: T Cell Lymphoma
• Interventions: Drug: Chidamide combined with BEAM

• Registration Number: NCT05367856
• Lead Sponsor: Ruijin Hospital

Brief Summary

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.

Detailed Description

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.

• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Chi-BEAM	Chidamide combined with BEAM	Patients in this arm will receive Chidamide Combined With BEAM(Carmustine, Etoposide Cytarabine and Melphalan) as Pretreatment Regimen of ASCT.

Primary Outcome Measures

Name	Time	Method
Progression free survival	Baseline up to data cut-off (up to approximately 2 years)	Progression-free survival was defined as the time from the date of ASCT until the date of the first documented day of disease progression or relapse, using 2014 Lugano criteria, or death from an cause, whichever occurred first.

Secondary Outcome Measures

Name	Time	Method
Overall survival	Baseline up to data cut-off (up to approximately 2 years)	Overall survival was defined as the time from the date of ASCT to the date of death from any cause.
Complete remission rate	3 months after the transplantation	Percentage of participants with complete response was determined on 2014 Lugano criteria.
The time of hematopoietic reconstruction	2 months after the transplantation	The first day of neutrophils ≥0.5×109/L for 3 consecutive days was the time of successful implantation of granulocytes. Platelet ≥20.0×109/L for 7 consecutive days and the first day after platelet infusion was considered as the successful time of megakaryocytes implantation.
Transplantation-related adverse reactions	Baseline up to data cut-off (up to approximately 4 years)	Transplantation-related adverse reactions are any untoward medical occurrence in a participant which is related to ASCT.
