Can a skin biopsy reveal how axatilimab fights scarring in chronic GVHD?
NCT ID NCT07728708
First seen Jul 27, 2026 · Last updated Aug 13, 2026 · Updated 3 times
Summary
This study investigates how axatilimab, an FDA-approved drug for chronic graft-versus-host disease (cGVHD), changes immune cells in the skin. Researchers will analyze skin and blood samples from 15 adults with skin cGVHD—10 starting axatilimab and 5 not receiving it—to understand how the drug reduces inflammation and scarring. The goal is to uncover biological markers that could improve future treatments for cGVHD and other fibrotic diseases.
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 successful, this study could reveal how axatilimab reduces skin inflammation and scarring in chronic GVHD, potentially guiding better treatments for this condition and other scarring diseases.
- What could go wrong
- This is a small observational study with only 15 participants, so findings may not apply broadly. It does not test new treatments or directly benefit participants.

Who is studied
Adults with chronic graft-versus-host disease (cGVHD) involving the skin who are receiving care at Northwestern Medicine. The study will enroll participants who are initiating axatilimab as part of routine clinical care and an observational comparison cohort of participants with skin cGVHD who are not initiating axatilimab.

Inclusion Criteria: * Age 18 years or older. * Diagnosis of chronic graft-versus-host disease (cGVHD) with skin involvement. * Planned initiation of axatilimab as part of routine clinical care (axatilimab arm) or not planning initiation of axatilimab as part of routine clinical care (control arm). * Able to undergo a skin biopsy at the time of enrollment. * Able to provide informed consent. Exclusion Criteria: * Unable to provide informed consent. * Contraindication to skin biopsy, including severe thrombocytopenia or other conditions that make skin biopsy unsafe in the judgment of the investigator. * Active uncontrolled infection.
