Spots Global Cancer Trial Database for Combination of ATG-based Conditioning Regimen and PTCy for GVHD Prevention in Allo-HSCT After PD-1 Blockade

Study Description

Brief Summary: The aim of this study is to evaluate the efficacy and safety of anti-thymocyte globulin combined with PTCy (post-HSCT cyclophosphamide, PTCy) in preventing graft-versus-host disease (GVHD) in allo-HSCT patients after anti-PD-1(anti-programmed cell death protein 1) antibody treatment. In this study, patients with hematological malignancies who needed to receive allo-HSCT after PD-1 antibody treatment were selected as the research subjects. Fludarabine and Busulfan was used as the conditioning regimen, and the dose of ATG (anti-thymocyte globulin, ATG) combined with PTCy was used as the GVHD prevention regimen. The aim of this study is to reduce the incidence of Regimen-Related Toxicity and GVHD without affecting engraftment and relapse, thereby reducing non-relapse mortality and further improving the survival of patients.

Detailed Description: ATG (anti-thymocyte globulin, rabbit; 5 mg/kg, day -5 to -2) was used in matched sibling donor-HSCT. ATG (1.5 mg/kg, day -5; 2.5 mg/kg, day -4; mathematical function was then exploited to determine the total targeted ATG dose on day -3 to -2 based on concentrations of active ATG on day -5 to -4) was used in both haploidentical donor-HSCT and unrelated donor-HSCT. Reduced-dose PTCy regimen: two doses of 14.5 mg/kg Cy were given on days +3 and +4 post-HSCT.
