Combination of Anti-thymocyte Globulin with Post-transplant Cyclophosphamide for GVHD Prophylaxis in Patients Undergoing Haploidentical Hematopoietic Stem Cell Transplantation: Systematic Review and Meta-analysis.
A new strategy combining anti-thymocyte globulin with post-transplant cyclophosphamide (ATG/PTCy) for graft-versus-host disease (GVHD) prevention was developed. This study aims to perform a systematic review and meta-analysis of studies comparing ATG/PTCy with ATG or PTCy in patients with hematological malignancies undergoing haploidentical hematopoietic stem cell transplantation. Meta-analysis was conducted with Review Manager version 5.4; pooled risk ratios (RRs) and hazard ratios (HRs) were calculated for dichotomous data and time-to-event data, respectively. A fixed-effects model was used if there was no significant heterogeneity. Literature search and study selection identified 14 eligible studies, including both randomized controlled trial and retrospective comparative studies. Different dosage adjustment strategies were applied; the total dose was 2.5-10 mg/kg for ATG and 29-100 mg/kg for PTCy. Meta-analysis results suggest that ATG/PTCy is associated with significantly lower risk of grades II-IV acute GVHD compared with ATG (RR 0.52; 95% CI: 0.41-0.65; P < .00001) and PTCy (RR 0.53; 95% CI: 0.34-0.83; P = .005) without increasing risk of disease relapse. In addition, ATG/PTCy is associated with significantly better overall survival and GVHD-free/relapse-free survival than ATG and PTCy. Future research is required to further establish the benefits of ATG/PTCy and determine the optimal dosage adjustment strategies.
Background: Haploidentical stem cell transplantation (haplo-HSCT) is associated with higher incidences of graft-versus-host disease (GVHD). A new strategy combining anti-thymocyte globulin with post-transplant cyclophosphamide (ATG/PTCy) for GVHD prevention has been developed, but its benefits and risks remain unclear.
Objective: This study aims to performs a systematic review and meta-analysis of studies comparing ATG/PTCy with ATG or PTCy in patients with hematological malignancies undergoing haplo-HSCT.
Study design: Literature search was performed in databases including Ovid Medline, Embase, Cochrane Library and China Biology Medicine (CBM). Two investigators independently screened eligible studies and extracted data. Meta-analysis was conducted with Review Manager version 5.4; pooled hazard ratios (HRs) for time-to-event outcomes were obtained using a generic inverse-variance method, and pooled risk ratios (RRs) for dichotomous data were obtained using the Mantel-Haenszel method. A fixed-effects model was adopted if there was no significant heterogeneity. The primary outcome is incidence of acute GVHD.
Results: Literature search and study selection identified 14 eligible studies, including both 1 randomized controlled trial and 13 retrospective comparative studies. Different dosage adjustment strategies were applied; the total dose was 2.5-10 mg/kg for ATG and 29-100 mg/kg for PTCy. Meta-analysis results suggest that ATG/PTCy is associated with significantly lower risk of grades II-IV acute GVHD compared with ATG (RR 0.52; 95% CI: 0.41-0.65; P < .00001) and PTCy (RR 0.53; 95% CI: 0.34-0.83; P = .005) without increasing risk of disease relapse. In addition, ATG/PTCy is associated with significantly lower risk of grades III-IV acute GVHD (RR 0.33; 95% CI: 0.23-0.49; P < .00001) and chronic GVHD (RR 0.65; 95% CI: 0.51-0.81; P = .0002) in comparison with ATG. Further analyses suggest that ATG/PTCy is associated with significantly better overall survival and GVHD-free/relapse-free survival than ATG and PTCy, but the risks of cytomegalovirus (RR 1.42; 95% CI: 1.03-1.95; P = .03) and Epstein Barr Virus (RR 3.17; 95% CI: 1.61-6.23; P = .0008) reactivation are higher when compared with PTCy.
Conclusions: Our results suggest that the combination of ATG with PTCy for GVHD prevention in haplo-HSCT is associated with improved efficacy but higher risk of infection. Future research is required to further establish the benefits and risks of ATG/PTCy and determine the optimal dosage adjustment strategies.
