Using ruxolitinib, tacrolimus, and methotrexate to prevent graft versus host disease in young patients after bone marrow transplant

Phase 2a Study of Adding Ruxolitinib With Tacrolimus/Methotrexate Regimen for Graft-versus-Host Disease Prophylaxis in Myeloablative Conditioning Hematopoietic Cell Transplantation in Pediatric and Young Adult Patients

Phase 2 Interventional City of Hope Medical Center · NCT06128070

This study is testing if a combination of three medications can help prevent graft versus host disease in young patients after they receive a bone marrow transplant for certain types of leukemia or blood disorders.

What this trial studies

This phase II trial evaluates the effectiveness and safety of combining ruxolitinib with tacrolimus and methotrexate to prevent graft versus host disease (GVHD) in pediatric and young adult patients undergoing allogeneic hematopoietic cell transplantation for acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome. Ruxolitinib is a kinase inhibitor that blocks inflammatory signals, while tacrolimus and methotrexate are immunosuppressants that help reduce the risk of transplant rejection and GVHD. The study aims to assess the one-year rates of GVHD-free and relapse-free survival, along with secondary outcomes related to acute and chronic GVHD, overall survival, and complications post-transplant.

Who should consider this trial

Good fit: Ideal candidates are pediatric and young adult patients aged 2-22 with hematologic malignancies who are eligible for allogeneic bone marrow transplantation.

Not a fit: Patients who do not have a matched donor or those with severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of graft versus host disease in young patients undergoing bone marrow transplants.

How similar studies have performed: Other studies have explored similar combinations of immunosuppressants for GVHD prevention, showing promising results, but this specific combination is relatively novel.
