Axatilimab for Sclerotic Chronic Graft-versus-Host Disease
brief summary
This phase II trial tests how well axatilimab works in treating patients with thickening or hardening (sclerosis) of the skin related to chronic graft-versus-host disease after a donor stem cell transplant. Chronic graft-versus-host disease (cGVHD) remains a major complication of donor stem cell transplants. Sclerosis, while not associated with a higher risk of death, can lead to serious disabilities. Usual treatments for cGVHD can be associated with significant side effects and unsatisfactory outcomes. A monoclonal antibody, like axatilimab, is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Axatilimab blocks a receptor and depletes cells that may be involved in the development of inflammation and fibrosis in cGVHD. Giving axatilimab may improve or prevent worsening of sclerosis related to cGVHD in patients after a donor stem cell transplant.
detailed description
OUTLINE:
Patients receive axatilimab IV over 30 minutes on days 1 and 15 of cycles 1-6 and then on day 1 of remaining cycles. Cycles repeat every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo blood sample collection throughout the study. Additionally, patients may undergo optional skin biopsies and optional skin flexibility assessments throughout the study.
After completion of study treatment, patients are followed up at 30 days then for up to 2 years.
