A Randomized Clinical Trial Comparing Chi-BEAM With BEAM Regimen Combined With ASCT for the Treatment of ND PTCL

A Randomized Controlled Clinical Trial Comparing Chidamide,Carmustine,Etoposide,Cytarabine and Melphalan With BEAM Regimen Combined With Autologus Hematopoietic Stem Cell Transplantation for the Treatment of Newly Diagnosed PTCL

The goal of this clinical trial is to compare Chi-BEAM With BEAM Regimen Combined With ASCT for the Treatment of ND PTCL.

The main question it aims to answer are:

•Whether Chi-BEAM improves patient survival compared to BEAM group Participants will be given BEAM or Chi-BEAM before ASCT. Researchers will compare the efficacy and safety of the two groups.

This is a prospective, multicenter, randomized controlled, open trial. The primary endpoint was 2-year PFS The secondary endpoint was： 2-year overall survival (OS). CR rate at 3 months post-transplant evaluation Hematopoietic reconstitution time Non-recurrent mortality (NRM)

Inclusion Criteria:

1. Pathologically diagnosed patients with newly treated PTCL (including NT/ K-cell lymphoma), except for ALK (+), have CR or PR after first-line treatment;
2. Renal function needs to be satisfied: creatinine clearance ≥80ml/min, creatinine less than 160μmol/L; Liver function requirements: ALT and AST≤2 times the upper limit of normal; Total bilirubin ≤2 times the upper limit of normal; Lung function should meet: FEV1, FVC, DLCO≥50% predictive value; Cardiac function must be satisfied: left ventricular ejection fraction ≥50%, asymptomatic arrhythmia.
3. Age between 18 and 65 years old, male and female;
4. ECOG physical strength score 0-1;
5. Neutrophil absolute value ≥1.5×109/L, platelets ≥ 70×109/L, hemoglobin ≥ 90g/L; Number of CD34+ cells ≥ 2.0×106/kg body weight;
6. Expected survival time ≥3 months;
7. Voluntarily sign written informed consent.

9. Pregnant and lactating women and women of childbearing age who do not want to take contraceptive measures;
10. The researcher determines that it is not suitable to participate in this study
