History
Efficacy was evaluated in AGAVE-201 (NCT04710576), a randomized, open-label, multicenter trial investigating three dosages of axatilimab in people with recurrent or refractory chronic graft-versus-host disease who had received at least two lines of systemic therapy and required additional treatment. Axatilimab was evaluated in an open-label single arm clinical trial of 79 participants with chronic graft-versus-host disease who had received at least two prior systemic treatments and required additional treatment. All participants received axatilimab 0.3 mg/kg every two weeks, until chronic graft-versus-host disease progression or unacceptable toxicity. The US Food and Drug Administration (FDA) approved axatilimab based on evidence of safety and efficacy from a clinical trial which included a total of 79 participants with chronic graft-versus-host disease after failure of two prior lines of systemic therapy. The trial was conducted at 55 sites in 13 countries, including Australia, Belgium, Canada, Germany, Greece, France, Israel, Italy, Spain, South Korea, Taiwan, the United Kingdom, and the United States. There were 24 sites in the United States. Out of 79 participants, at the approved dose of 0.3 mg/kg every two weeks, 37 participants were enrolled in the United States, and 43 participants at the trial sites outside of the United States.
The FDA granted the application for axatilimab orphan drug and fast track designations for the treatment of chronic graft-versus-host disease.
