Summary

Myelofibrosis (MF) is a myeloproliferative neoplasm causing bone marrow failure and high risk of leukemia transformation. JAK2 inhibitors improve symptoms but do not cure MF. Allogeneic stem cell transplantation (allo-HSCT) is the only potential cure, though limited donor availability restricts access. Haploidentical transplantation shows promise but associated with higher graft failure and treatment related mortality. We recently developed a novel regimen of haplo-SCT for MF. This study aims to investigate this novel protocol in a prospective trial to improve MF outcomes.

PROCEDURE

Haploidentical hematopoietic stem cell transplantation

This is a single-arm study in which all patients will undergo haploidentical hematopoietic stem cell transplantation for the treatment of myelofibrosis. Pre-transplant Evaluation: Evaluation includes status of primary Disease, donor specific antibodies (DSA), organ function (assessments for heart, liver, lungs, kidneys, and the nervous system), and Spleen size. Transplantation Protocol: Conditioning Regimen: Dac/TT/Bu/Flu/ATG regimen: Decitabine 100 mg/m², on day -12. Thiotepa (TT) 5 mg/kg/day, on days -11 and -10. Busulfan 0.8 mg/kg body weight, every 6 hours, on days -8 to -6. Fludarabine 30 mg/m², once daily, on days -6 to -2. Anti-thymocyte globulin (ATG) 2.5 mg/kg body weight, once daily, on days -5 to -2. Transplant Donor: Haploidentical donor. GVHD (Graft-versus-Host Disease) Prophylaxis Regimen: Cyclosporine, mycophenolate mofetil, and short-course methotrexate for GVHD prevention. Graft: Target MNC (Mononuclear Cells): 6-8 × 10⁸/kg. Target CD34+ stem cells: 5 × 10⁶/kg
