New hope for kids with chronic Graft-Versus-Host disease: axatilimab trial launches
NCT ID NCT07124078
First seen Jun 24, 2026 · Last updated Sep 16, 2026 · Updated 5 times
Summary
This study tests a drug called axatilimab against the best available treatments for children aged 2 to 18 with chronic graft-versus-host disease (cGVHD), a complication after a stem cell transplant. The trial enrolls 60 participants who have already tried at least two other treatments. The goal is to see if axatilimab can improve symptoms better than current options.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- axatilimab
- What this could lead to
- If it works, this could offer a new treatment option for children with chronic graft-versus-host disease who have not responded to other therapies.
- What could go wrong
- This is a mid-stage trial with only 60 participants, so results may not apply to all patients. The drug may not work better than existing options, and side effects 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: * Aged 2 to \< 18 years at the time of randomization. * Active, moderate to severe cGVHD, requiring systemic immune suppression. * Participants with refractory or recurrent cGVHD who have received at least 2 lines of systemic therapy, including corticosteroids and ruxolitinib. * Concomitant use of systemic corticosteroids is allowed. Participants on systemic corticosteroids must be on a stable dose of corticosteroids for at least 2 weeks prior to C1D1. Topical and inhaled corticosteroid agents are allowed. * Participants must accept to be treated with one of the following BAT options on C1D1: CNI (cyclosporine or tacrolimus), ECP, MMF, an mTOR inhibitor (everolimus or sirolimus), rituximab, imatinib, methotrexate, ibrutinib, or pentostatin. * 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. Exclusion Criteria: * Receipt of more than 1 prior allo-HCT. Prior autologous HCT is allowed, including autologous CAR T-cell therapy given before the allo-SCT. * Documented evidence of relapse of the primary hematologic disease or receipt of treatment for relapse after allo-SCT, including DLI for treatment of any malignancy relapse, including molecular relapse. Autologous and allogeneic donor-derived CAR T-cell therapy after allo-SCT are not allowed. Note: Participants who received DLI solely for the management of mixed chimerism or as part of the planned transplant procedure and not for treatment of malignancy relapse (including molecular relapse), are eligible. * Systemic treatment with CNIs or mTOR inhibitors started within 2 weeks prior to C1D1. * Severe renal impairment, that is, GFR \< 30 mL/min/1.73 m2 as estimated using modified Schwartz formula, or end-stage renal disease on dialysis. * Impaired liver function, defined as total bilirubin \> 1.5 × ULN or ALT \> 3 × ULN or AST \> 3 × ULN in participants with no evidence of liver cGVHD. * History of acute or chronic pancreatitis. * Active, symptomatic myositis. * Female adolescent participants who are pregnant or breastfeeding. Other protocol-defined Inclusion/Exclusion Criteria may apply.
