Clinical Trial Summary

A novel regimen, which is composed of a low dose of ATG (5 mg/kg) and low-dose PTCy (one dose of PTCy, 50mg/kg) for GvHD prophylaxis in Haplo-PBSCT for patients with hematologic malignancies, was designed to decrease the risk of aGvHD and lower the incidence of virus reactivation.

Description:

Acute graft-versus-host disease (aGvHD) is the most important obstacle of haploidentical hematopoietic stem cell transplantation (Haplo-HSCT) for treatment of patients with hematologic malignancies. In the last two decades, the results of Haplo-HSCT have been conspicuously improved due to effective prophylaxis strategies for aGvHD, such as in vivo T cell depletion (TCD) with anti-thymocyte globulin (ATG) or post-transplant cyclophosphamide (PTCy).

The regimens for prophylaxis of GvHD based on rabbit anti-human thymocyte immunoglobin (ATG 10mg/kg, Thymoglobin®, Genzyme Polyclonals S.A.S) effectively prevented the occurrence of grade II-IV aGvHD with an incidence of 33.4%-46%, grade III-IV aGvHD 12%-14.9%, but the reactivation incidences of cytomegalovirus (CMV) and EB virus (EBV) were higher due to a slower immune reconstitution(2-4). The 100-day CIs of CMV and EBV viremia were 61%-64%and over 50%, respectively. Although ATG-based regimens have achieved excellent results, the incidences of aGvHD and the post-transplant virus reactivation are still higher, affecting the long-term survival of the patients.

The regimen of PTCy for prevention of GvHD was developed in 1999 by St. Johns Hopkin's group in Baltimore (1) and had outstanding results with the CIs of 34% grades II-IV and of 6% grades III-IV aGvHD by day 200 in haplo-bone marrow transplantation (Haplo-BMT) (7), respectively. The incidences of viral and fungal infection in Haplo-HSCT with PTCy for GvHD prophylaxis were much lower than ATG based regimens. Ruggeri A（8）et al retrospectively analyzed the effects of different stem cell source (BM vs PBSC) on the transplant results in Haplo-HSCT with PTCy. The results showed that BM was associated with a lower incidence of grades II-IV and grades III-IV acute GVHD (21% vs 38%, P ≤ .01; and 4% vs 14%, P < .01, respectively), which was further confirmed by Bashey A et al' study（9）. These data indicated that PTCy regimen don't have the same effects for GvHD prophylaxis with PBSC graft as compared with BM graft in Haplo-HSCT.

A novel regimen, which is composed of a low dose of ATG (5 mg/kg) and low-dose PTCy (one dose of PTCy, 50mg/kg) for GvHD prophylaxis in Haplo-PBSCT for patients with hematologic malignancies, was designed to decrease the risk of aGvHD and lower the incidence of virus reactivation. A prospective, phase II clinical trial (Clinicaltrials.org NCT03395860) was performed to evaluate the efficacy with low dose ATG followed by low dose PTCy as GvHD prophylaxis.Thirty-two patients diagnosed with hematological malignancies were enrolled in this trial. All patients received myeloablative conditioning regimens except for three patients. The cumulative incidences (CIs) of grades II-IV and III-IV acute GvHD were 19.4% (95% CI, 5.5-33.3%) and 6.9% (95% CI 0-16.3%) by day 100, respectively. The one-year probability of relapse was 25.1% (95% CI, 7.3-42.9%). The one-year probabilities of disease free-survival (DFS) and overall survival (OS) was 59% (95% CI, 33.3%-84.7%) and 78.4% (95% CI, 63%-93.8%), respectively. The CIs of CMV reactivation and EBV reactivation by day 180 were 37.5% (95% CI, 19.8-55.2%) and 40.6% (95% CI, 22.6-58.6%), respectively. The results suggested that low dose ATG with low dose PTCy as GvHD prophylaxis in Haplo-PBSCT had promising activity. A prospective randomized trial is required to compare the efficacies of this regimen with ATG-based or PTCy-based regiments in Haplo-PBSCT.
