This is a Phase 2 study to evaluate the efficacy, safety, and tolerability of axatilimab at 3 different dose levels in participants with recurrent or refractory active chronic graft versus host disease (cGVHD) who have received at least 2 prior lines of systemic therapy.
AGAVE-201 is a Phase 2, open-label, randomized, multicenter study to evaluate the efficacy, safety, and tolerability of axatilimab in participants with recurrent or refractory active cGVHD after failure of at least 2 prior lines of systemic therapy due to progression of disease, intolerability, or toxicity. Participants will be randomized to receive 1 of 3 different axatilimab treatment regimens in 28-day treatment cycles for up to 2 years.
Inclusion Criteria: 1. Participants must be 2 years of age or older, at the time of signing the informed consent. 2. Participants who are allogeneic hematopoietic stem cell transplantation (HSCT) recipients with active cGVHD requiring systemic immune suppression. Active cGVHD is defined as the presence of signs and symptoms of cGVHD per 2014 NIH Consensus Development Project on Criteria for Clinical trials in cGVHD. 3. Participants with refractory or recurrent active cGVHD despite at least 2 lines of systemic therapy. * Refractory disease defined as meeting any of the following criteria:…
Axatilimab is a high-affinity antibody targeting the colony stimulating factor 1 receptor (CSF-1R). CSF-1R signaling has been demonstrated in nonclinical studies to be the key regulatory pathway involved in the expansion and infiltration of donor-derived macrophages that mediate the disease processes involved in cGVHD.
