What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 42 participants in total. It began in 2026-06-01 with a primary completion date of 2028-06-22.

Brief Summary

This phase I trial studies how well biomarker-guided ruxolitinib works for the prevention of chronic graft versus host disease (GVHD) in patients that have undergone allogeneic hematopoietic cell transplant (HCT). Allogeneic HCT is the most effective therapy for patients with high-risk blood and bone marrow malignancies. GVHD is a disease caused when cells from a donated stem cell graft attack the normal tissue of the transplant patient. Symptoms include jaundice, skin rash or blisters, a dry mouth, or dry eyes. In chronic GVHD (cGVHD), symptoms occur more than three months after transplantation. Despite significant advances in how allogeneic HCTs are conducted, cGHVD remains a major limitation to the long-term success of the transplant and can impact patients' quality of life post-transplant. Checking GVHD biomarkers in patients' blood after allogeneic HCT may help doctors predict how likely the patient is to develop cGVHD. This information can be used to help guide patients with high levels to receive cGVHD preventative therapy with ruxolitinib. Ruxolitinib works by blocking some of the enzymes that are needed for the development of cGVHD, which may be an effective way to prevent cGVHD in patients with high levels of GVHD biomarkers.
