Can a new pill tame GVHD after transplant?
NCT ID NCT03139604
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This large Phase 3 study tested whether adding the drug itacitinib to standard steroids helps control acute graft-versus-host disease (GVHD) in people who had a stem cell transplant for blood cancer. About 439 participants received either itacitinib or a placebo along with steroids. The main goal was to see if more people responded to treatment with itacitinib.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- itacitinib (a drug taken by mouth that blocks inflammation)
- What this could lead to
- If it works, this could offer a new first-line treatment option to better control acute graft-versus-host disease after a stem cell transplant.
- What could go wrong
- This is a completed Phase 3 trial, but results are not yet widely reported. The drug may not improve response rates over standard steroids alone, and side effects like infection risk are possible.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Has undergone 1 allo-HSCT from any donor (related or unrelated with any degree of HLA matching) and any donor source (bone marrow, peripheral blood stem cells, or cord blood) for a hematologic malignancy or disorder. Recipients of myeloablative and reduced-intensity conditioning regimens are eligible. * Clinically suspected Grade II to IV aGVHD as per MAGIC criteria, occurring after allo-HSCT and any GVHD prophylaxis regimen. * Evidence of myeloid engraftment. Use of growth factor supplementation is allowed. * Serum creatinine ≤ 2.0 mg/dL or creatinine clearance ≥ 40 mL/min measured or calculated by Cockroft Gault equation. * Willing to avoid pregnancy or fathering children. * Able to give written informed consent and comply with all study visits and procedures. * Able to swallow and retain oral medication. Exclusion Criteria: * Has received more than 1 allo-HSCT. * Has received more than 2 days of systemic corticosteroids for aGVHD. * Presence of GVHD overlap syndrome. * Presence of an active uncontrolled infection. * Known human immunodeficiency virus infection. * Active hepatitis B virus (HBV) or hepatitis C virus infection that requires treatment or at risk for HBV reactivation. * Participants with evidence of relapsed primary disease, or participants who have been treated for relapse after the allo-HSCT was performed. * Any corticosteroid therapy for indications other than GVHD at doses \> 1 mg/kg per day methylprednisolone (or prednisone equivalent) within 7 days of randomization. * Severe organ dysfunction unrelated to underlying GVHD, including: * Cholestatic disorders or unresolved veno-occlusive disease of the liver. * Clinically significant or uncontrolled cardiac disease. * Clinically significant respiratory disease that requires mechanical ventilation support or 50% oxygen. * Currently breast feeding. * Received JAK inhibitor therapy after allo-HSCT for any indication. Treatment with a JAK inhibitor before allo-HSCT is permitted. * Treatment with any other investigational agent, device, or procedure within 21 days (or 5 half-lives, whichever is greater) of enrollment. * Any medical complications or conditions that would, in the investigator's judgment, interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data. * Known allergies, hypersensitivity, or intolerance to any of the study medications, excipients, or similar compounds.
