Adding Itacitinib to Cyclophosphamide and Tacrolimus for the Prevention of Graft Versus Host Disease in Patients Undergoing Hematopoietic Stem Cell Transplants (NCT05364762)

Single Center Pilot Study to Investigate the Efficacy of Adding Itacitinib to Post-Transplant Cyclophosphamide as Graft-Versus-Host Disease Prophylaxis After Reduced Intensity Conditioning Matched Donor Hematopoietic Cell Transplantation With Peripheral Blood Stem Cells as Graft Source

🔵 Active, Not Recruiting Phase2 💊 Investigational Drug / Biologic Sponsor: City of Hope Medical Center

🩺 Plain-English Summary (8th-Grade Level)

This clinical trial evaluates the safety and effectiveness of adding itacitinib to cyclophosphamide and tacrolimus for the prevention of graft versus host disease (GVHD) in patients undergoing hematopoietic stem cell transplant. Itacitinib is an enzyme inhibitor that may regulate the development, proliferation, and activation of immune cells important for GVHD development. Cyclophosphamide and tacrolimus are immunosuppressive agents that may prevent GVHD in patients who receive stem cell transplants. Giving itacitinib in addition to cyclophosphamide and tacrolimus may be more effective at preventing GVHD in patients receiving hematopoietic stem cell transplants.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (29 items) and avoid the listed exclusions (13 items).

Location: City of Hope Medical Center — Duarte, California

Usually NOT eligible if any of the following apply:

  • Exclusion Criteria:
  • Prior allogeneic HCT
  • Chemotherapy, radiation therapy, biological therapy, immunotherapy within 21 days prior to day 1 of protocol therapy
  • Note: Conditioning regimen within 21 days prior to day 1 of protocol therapy is not considered as an exclusion criterion. Patients on maintenance chemotherapy are not excluded
  • Other investigational drugs for treatment of GVHD
