New combo therapy aims to tame chronic GVHD
NCT ID NCT06585774
First seen Jun 24, 2026 · Last updated Sep 16, 2026 · Updated 9 times
Summary
This study tests whether adding axatilimab to standard steroid treatment helps people with moderate to severe chronic graft-versus-host disease (cGVHD), a complication after stem cell transplant. About 240 participants aged 12 and older will receive either axatilimab or a placebo, plus steroids. The main goal is to see if the combination delays disease worsening or death.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- axatilimab (a drug given by IV) plus corticosteroids (steroids)
- What this could lead to
- If it works, this could become a new standard first treatment for chronic GVHD, helping patients live longer without the disease getting worse.
- What could go wrong
- This is an early-stage Phase 3 trial, so results are not guaranteed. The drug may not improve outcomes over steroids alone, and side effects like infections or infusion reactions are possible.
This is an AI summary of the original study and may miss details. Read our disclaimer.

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 allo-HCT from any donor HLA type (related or unrelated donor with any degree of HLA matching) using any graft source (bone marrow, peripheral blood stem cells, or cord blood). Recipients of myeloablative, nonmyeloablative, or reduced-intensity conditioning are eligible. * Adequate hematologic function with ANC ≥ 0.5 × 109/L independent of growth factors for at least 7 days prior to study entry. * Willingness to avoid pregnancy or fathering children. Exclusion Criteria: * Received more than 1 prior allo-HCT. Prior autologous HCT is allowed. * Has overlap cGVHD, defined as simultaneous presence of features or characteristics of aGVHD in a patient with cGVHD. * Received more than 7 days of systemic corticosteroid treatment for cGVHD or unable to begin a prednisone dose ≥ 1.0 mg/kg per day (or methylprednisolone equivalent) for cGVHD. * Received previous systemic treatment for cGVHD, including extracorporeal photopheresis. * Systemic treatment with CNIs or mTOR inhibitors started within 2 weeks prior to C1D1. * Prior treatment with CSF-1R targeted therapies. * Active, uncontrolled bacterial, fungal, parasitic, or viral infection. * Evidence of relapse of the primary hematologic disease or treatment for relapse after the allo-HCT was performed, including DLIs for the treatment of molecular relapse. * History of acute or chronic pancreatitis. * Active symptomatic myositis. * History or current diagnosis of cardiac disease indicating significant risk of safety for participation in the study, such as uncontrolled or significant cardiac disease. * 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 endstage renal disease on dialysis. * 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. * Pregnant or breastfeeding. Other protocol-defined Inclusion/Exclusion Criteria may apply.
