The role of donor CMV serostatus in the setting of non T-cell depleted haplo-HSCT with post-transplant cyclophosphamide (PT-Cy) has not been specifically addressed so far. Here we analyzed the impact of the donor CMV serological status on the outcome of 983 CMV seropositive (CMV+), acute leukemia patients receiving a first, non T-cell depleted haplo-HSCT registered in the EBMT database. The 1-year NRM was 21.3% (95% CI: 18.4-24.8) and 18.8% (95% CI: 13.8-25.5) in the CMV D+P/R+ and D-/R+ pairs, respectively (p = 0.40). Similarly, 1-year OS was 55.1% (95% CI: 50.1-58.0) and 55.7% (95% CI: 48.0-62.8) in the same groups (p = 0.50). The other main outcomes were comparable. No difference in NRM nor OS was observed after stratification for the intensity of conditioning and multivariate anaysis confirmed the lack of significant association with NRM or OS. In conclusion, the choice of a CMV-seronegative donor did not impair early survival of CMV-seropositive patients with acute leukemia after a first, non T-cell depleted haploidentical HSCT and PT-Cy among this series of 983 consecutive patients. Future research may focus on the assessment of the hierarchy of all the donor variables.

The results of haploidentical stem cell transplantation (haploHCT) for patients with acute lymphoblastic leukemia (ALL) transplanted in active disease remain largely unknown. We retrospectively analyzed adult patients with R/R ALL who underwent haploHCT or matched sibling donor (MSD-HCT) as a first transplantation between 2012 and 2020. The analysis comprised 274 patients, 94 had a haploHCT, and 180 had an MSD-HCT. The median follow-up was 32 months. The median age was 33 (range 18-76) and 37 (18-76) years in the haplo- and MSD-HCT groups, respectively. Post-transplant cyclophosphamide (PTCy) was used in 88% of haploHCT and in 4% of the MSD-HCT group. Graft-versus-host disease grade III-IV was higher in haploHCT than in the MSD-HCT group (18% versus 9%; P = 0.042). The 2-year chronic (c) graft-versus-host disease rates were 17% versus 33% (hazard ratio [HR] = 0.56; P = 0.14), respectively. By multivariate analysis, relapse incidence, and leukemia-free survival were not significatively different between the transplant groups, while nonrelapse mortality (NRM) was significantly higher (25% versus 18% at 2 years; HR = 2.03; P = 0.042) and overall survival (OS) lower (22% versus 38% at 2 years; HR = 1.72; P = 0.009) in the haploHCT group compared with the MSD-HCT group. We conclude that the 2-year OS of R/R ALL patients undergoing MSD transplants is significantly better than in haploHCT with a higher NRM in the latter.

Graft-versus-host disease (GvHD) prophylaxis for unmanipulated haploidentical hematopoietic cell transplantation includes posttransplant cyclophosphamide (PTCy) and anti-thymocyte globulin (ATG). Utilizing data in the European Society for Blood and Marrow Transplantation registry, we compared ATG- versus PTCy-based GvHD prophylaxis in 434 adults with acute lymphoblastic leukemia undergoing haploidentical hematopoietic cell transplantation. Of the 434 patients included in this study, ATG was used in 98 and PTCy in 336.. The median follow-up was approximately 2 years. The baseline characteristics of the patients were similar between the groups except that the ATG group was more likely to have had relapsed/refractory acute lymphoblastic leukemia (P=0.008), had conditioning not including total body irradiation (P<0.001), have had peripheral blood as the source of their grafts (P=0.001) and to have been transplanted in an earlier timeperiod (median year of transplantation: 2011 vs. 2015). The 100-day rates of grade II-IV and III-IV acute GvHD were similar in the ATG and PTCy groups, as were 2-year chronic GvHD rates. On multivariate analysis, leukemia-free survival and overall survival were better with PTCy than with ATG prophylaxis. Relapse incidence was lower in the PTCy group (P=0.03), while non-relapse mortality was not different. Advanced disease and lower performance score were associated with poorer leukemia-free survival and overall survival and advanced disease was associated with inferior GvHD-free/relapse-free survival. Compared to bone marrow grafts, peripheral grafts were associated with higher rates of GvHD. In patients with acute lymphoblastic leukemia undergoing unmanipulated haploidentical hematopoietic cell transplantation, PTCy for GvHD prevention resulted in a lower incidence of relapse and improved leukemia-free survival and overall survival, compared to ATG.
