Ruxolitinib to prevent graft-versus-host disease after allogeneic stem cell transplant
Official title: Randomized Pilot Study of Ruxolitinib for Switch-Maintenance Prophylaxis of Graft-versus-Host Disease in Allogeneic Hematopoietic Cell Transplantation After Intermediate-Dose Post-Transplant Cyclophosphamide (Rux Switch-Maintenance in Intermediate PTCY: RuSMa-PTCY) in Comparison to Full-Dose PTCY
Run by Memorial Sloan Kettering Cancer Center · NCT07359859 · Data updated 2026-11-12
This trial will test whether adding ruxolitinib to standard drugs better prevents chronic graft-versus-host disease in adults receiving an allogeneic stem cell transplant for blood cancers.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with a hematologic malignancy in morphologic remission who are planning an allogeneic stem cell transplant from a 7-8/8 HLA-matched related or unrelated donor or a related haploidentical donor, with Karnofsky score ≥70% and appropriate reproductive safety measures, are eligible.
✕Probably not a fit
Patients with active uncontrolled malignancy, poor performance status, incompatible donors, or contraindications to the study drugs or required contraception are unlikely to benefit from this protocol.

What this trial studies
This Phase 2 interventional trial compares two different GVHD prophylaxis regimens in adults undergoing allogeneic hematopoietic stem cell transplantation for hematologic malignancies. Participants will receive one of two prophylaxis approaches that include combinations of post-transplant cyclophosphamide, tacrolimus, mycophenolate mofetil, and ruxolitinib. The primary outcome is the incidence of chronic GVHD up to one year after transplant, with safety and transplant-related outcomes also monitored. The trial is conducted at Memorial Sloan Kettering Cancer Center locations in New Jersey.
Why it matters
Potential benefit: If successful, this approach could reduce the incidence and long-term complications of chronic GVHD for transplant recipients.
How similar studies have gone: Ruxolitinib is approved for treating steroid-refractory GVHD and smaller studies have suggested it may help prevent GVHD, but prophylactic use after allo-HCT remains under investigation.

Inclusion Criteria: * Patients ≥18- years-old at time of consent * Diagnosis: hematologic malignancy in morphologic remission (blasts \<5%, no evidence of extramedullary disease in AML or MDS). Patients with CR with incomplete count recovery (CRp or CRi) or minimal residual disease are allowed. Patients with lymphoma must have a complete or partial response * Donor: related or unrelated 7-8/8 HLA-matched or related haploidentical * Karnofsky score ≥ 70% * Female subjects of childbearing potential (\<50 years old) have a negative serum or urine pregnancy test. Females of childbearing potential are defined as females without prior hysterectomy or who have had any evidence of menses in the past 12 months. °Sexually active females of childbearing potential enrolled in the study must agree to consistently use two forms of accepted methods of contraception during the course of the study and for 3 months after their last dose of the study drug. Effective birth control includes: \*Intrauterine device (IUD) plus one barrier method \*Stable doses of hormonal contraception for at least 3 months (e.g., oral, injectable, implant, transdermal) plus one barrier method \*2 barrier methods. Effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gel that contain a chemical to kill sperm); or \* A vasectomized partner. * For male subjects who are sexually active and who are partners of females of childbearing potential: Agreement to use two forms of contraception as per above and to not donate sperm during the treatment period and for at least 3 months after the last dose of study drug Exclusion Criteria: * Recipient of CD34+ selected or engineered stem cell graft * Treatment with in vivo T cell depletion (e.g. anti-thymocyte globulin) * Patients with an active secondary malignancy or prior malignancy requiring systemic therapy within the past 5 years. Exceptions include adequately treated localized non-melanoma skin cancer (basal cell carcinoma and squamous cell carcinoma), as well as localized prostate cancer considered low risk and stable under treatment or surveillance. * Severely impaired renal function defined by serum creatinine \> 2mg/dL, renal dialysis requirement. * Use of investigational agent within 14 days pre-HCT * Evidence of current uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial infarction within the past 6 months * Uncontrolled psychiatric illness * Female patient who is pregnant or breastfeeding * Known allergy or sensitivity to ruxolitinib
