New drug duo aims to tame Graft-Versus-Host disease
NCT ID NCT06388564
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 trial tests whether adding axatilimab to the standard drug ruxolitinib works better for people newly diagnosed with moderate to severe chronic graft-versus-host disease (cGVHD), a complication after stem cell transplant. About 130 participants aged 12 and older will receive the combination or standard care. The main goal is to see if the combination leads to a complete or partial response within 6 months without needing new therapy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- axatilimab and ruxolitinib
- What this could lead to
- If successful, this combination could offer a more effective first-line treatment for chronic graft-versus-host disease, potentially reducing the need for long-term steroids.
- What could go wrong
- This is an early Phase 2 trial with only 130 participants, so results may not apply to everyone. Side effects from the drug combination are possible, and the study is not yet complete.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * ≥ 12 years of age at the time of informed consent. * New-onset moderate or severe cGVHD, as defined by the 2014 NIH Consensus Development Project Criteria for Clinical Trials in cGVHD, requiring systemic therapy. * History of 1 allo-SCT (any type of stem cell donor, any conditioning regimen, and source of hematopoietic stem cells). * Adequate hematologic function independent of platelet transfusion and growth factors for at least 7 days prior to study entry: ANC ≥ 0.75 × 109/L and platelet count ≥ 20 × 109/L. * Willingness to avoid pregnancy or fathering children. Exclusion Criteria: * Received more than 1 prior allo-SCT. Prior autologous HCT is allowed. * Has overlap cGVHD, defined as simultaneous presence of features or characteristics of aGVHD in a patient with cGVHD. * Received previous systemic treatment for cGVHD, including systemic corticosteroids and extracorporeal photopheresis. * Received systemic corticosteroids within 2 weeks prior to C1D1, regardless of indication. * Initiated systemic treatment with CNIs or mTOR inhibitors within 2 weeks prior to C1D1. * Prior treatment with a JAK inhibitor within 8 weeks before randomization. Participants who received a JAK inhibitor for the treatment of aGVHD are eligible only if they achieved a response (CR or PR) to JAK inhibitor treatment and did not discontinue due to toxicity. * Evidence of relapse of the primary hematologic disease or treatment for relapse after the allo-SCT was performed, including DLIs for the treatment of molecular relapse. * History of acute or chronic pancreatitis. * History of thromboembolic events (such as deep vein thrombosis, pulmonary embolism, stroke, myocardial infarction) in the 6 months prior to study entry. * Active symptomatic myositis. * Severe renal impairment, that is, estimated CrCl \< 30 mL/min measured or calculated by Cockcroft-Gault equation in adults and Schwartz formula in pediatric participants, or end-stage renal disease on dialysis. Participants with CrCl of 30 to 59 mL/min on treatment with fluconazole are not eligible. * Impaired liver function, defined as total bilirubin \> 1.5 × ULN and/or ALT and AST \> 3 × ULN in participants with no evidence of liver cGVHD. * Currently active significant cardiac disease, such as uncontrolled arrhythmias, uncontrolled hypertension, or Class 3 or 4 congestive heart failure as defined by New York Heart Association, or a history of myocardial infarction or unstable angina within 6 months prior to randomization. * Pregnant or breastfeeding. Other protocol-defined Inclusion/Exclusion Criteria may apply.
