Summary

GVHD prevention using a combination of post-transplantation cyclophosphamide in combination with abatacept, vedolizumab and Ruxolitinib in children and young adults with hematoloblastosis after myeloablative conditioning regimen with treosulfan/TBI, etoposide, fludarabine after HSCT from matched unrelated and haploidentical donors

Conditions

Interventions

DRUG

Conditioning regimen: Treosulfan 42 g/m2/course or total body irradiation 12 Gray/course, Etoposide 60 mg/kg , Fludarabine 150

The most significant adverse events limiting the use of HSCT from an unrelated donor are graft-versus-host disease (GVHD) and prolonged immunodeficiency associated with the development of severe infectious complications. The use of post-transplant cyclophosphamide for the prevention of GVHD during allogeneic HSCT from unrelated and haploidentical donors has reduced the incidence of acute clinically significant GVHD in children to 25%, chronic GVHD to 12-30%, but the issue of GVHD control still remains extremely relevant. Emerging data on the use of abatacept, a selective blocker of the costimulatory signal from an antigen-presenting cell, in the prevention of intestinal GVHD and data on the effectiveness of Janus-kinase type 1/2 inhibitors (JAK-1/2) in the treatment and prevention of acute GVHD allow us to justify the use of these drugs in combination with post-transplant cyclophosphamide as a promising pharmacological platform for the prevention of GVHD.
