Study Arms (1)

Prevention of GVHD: Cyclophosphamide, Abatacept, Vedolizumab, Ruxolitinib

EXPERIMENTAL

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

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

Interventions

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.

Prevention of GVHD: Cyclophosphamide, Abatacept, Vedolizumab, Ruxolitinib

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • \. Patients under the age of 21 years with following diseases:

  • myeloblastic,
  • biphenotypic,
  • bilinear leukemia,
  • malignant lymphoma,
  • myelodysplastic syndrome,

You may not qualify if:

  • Clinical status:
  • Lansky/Karnowski index \<70% (supplement No.1)
  • Heart function: left ventricular ejection fraction \<40% according to ultrasound of the heart1
  • Kidney function: clearance of endogenous creatinine \< 70 ml / min
  • Liver function: total bilirubin, ALT, AST, ALP \> 2 norms
  • Lung function: lung capacity \<50%, for children who cannot carry out of respiratory function - oxygen saturation during pulse oximetry \<92%
  • Uncontrolled viral, fungal or bacterial infection.
  • Mental illness of the patient or caregivers, making it impossible to realize the essence of the study and compromising compliance with medical appointments and sanitary and hygienic regime 1 These patients may receive treatment according to the protocol, but the results will be evaluated separately
