NCT ID NCT07728708

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

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 can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

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.
