Syndax/Incyte Plan BLA for Axatilimab

Share

Syndax Pharmaceuticals and Incyte say they plan to file by the end of the year a BLA for axatilimab, for use in adult and pediatric patients with chronic graft-versus-host disease (GVHD) following two or more prior lines of therapy. Just-reported pivotal trial (AGAVE-201) data showed that the therapy met its primary endpoint of overall response rate, according to the companies.

Among responders treated with 0.3 mg/kg of axatilimab, 60% of patients maintained a response at 12 months, Syndax and Incyte say. “Additionally, in the 0.3 mg/kg group, 55% of patients experienced a clinically meaningful improvement in symptoms, as measured by at least a seven-point decrease in the modified Lee chronic GVHD Symptom Scale score,” they add.

“Axatilimab is the first investigational chronic GVHD treatment to target inflammation and fibrosis through the inhibition of disease associated macrophages, and the AGAVE-201 data demonstrates the potentially pronounced impact this mechanism, alone or in combination with standard-of-care therapies already available for the management of this disease, may have on patients suffering from chronic GVHD,” the companies say.
