Integrating Axatilimab Into cGVHD Care: Insights From AGAVE-201

A panelist discusses how chronic graft-vs-host disease (cGVHD) is a common posttransplant complication with increasing incidence due to peripheral blood stem cell grafts, older patients, and more unrelated donor transplants, which can manifest in multiple organs and is typically treated with corticosteroids as first-line therapy.

A panelist discusses how axatilimab, a humanized IgG4 monoclonal antibody targeting CSF-1 receptors on monocytes and macrophages, showed promising results in the AGAVE-201 trial for treatment-resistant chronic graft-vs-host disease (cGVHD), with high response rates, durable responses, and tolerable adverse effects at the FDA-approved dose of 0.3 mg/kg every 2 weeks.

A panelist discusses how axatilimab demonstrated efficacy in a heavily pretreated patient population with predominantly severe chronic graft-vs-host disease (cGVHD) in the AGAVE-201 trial, with manageable adverse effects including infusion reactions and enzyme elevations that rarely required discontinuation of treatment.

A panelist discusses how axatilimab is particularly effective for patients with bronchiolitis obliterans syndrome, showing response rates of almost 50% with 20% complete responses, and offers the advantage of reliable intravenous delivery despite logistical challenges of infusion center visits.

A panelist discusses how community-based care coordination can be implemented for patients with chronic graft-vs-host disease (cGVHD) on axatilimab, with initial cycles administered at specialized centers followed by local infusions under community oncologist supervision, with periodic assessment visits to evaluate treatment response.

A panelist discusses how advances in chronic graft-vs-host disease (cGVHD) prevention include posttransplant cyclophosphamide showing significant reduction in moderate to severe cGVHD and the promising Precision-T trial using split-dose infusions of regulatory T cells followed by conventional T cells, both demonstrating improved cGVHD-free survival compared with standard prophylaxis.
