"cGVHD is a highly underserved area in dire need of innovative new therapeutic options," said
"The compelling data reported today demonstrate durable responses across all dose levels in several organs, including multiple organ-specific complete responses, and continue to support axatilimab's potential to serve as a novel, safe, and effective therapy for patients with cGVHD," said
Axatilimab was generally safe and well-tolerated. The most common observed adverse events were consistent with on-target effects on liver enzyme pharmacology. There was no incidence of cytomegalovirus (CMV) or other viral reactivation and no apparent increases in risk for infection. Enrollment remains ongoing in the Phase 2 portion of the Phase 1/2 trial at a dose of 1 mg/kg every two weeks.
The Company plans to commence a pivotal Phase 2 trial, AGAVE-201, to assess the safety and efficacy of different doses and schedules of axatilimab for the treatment of patients with cGVHD. The primary endpoint will assess objective response rate based on the 2014
About Chronic Graft Versus Host Disease
Chronic graft versus host disease (cGVHD), an immune response of the donor-derived hematopoietic cells against recipient tissues, is a serious, potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation (HSCT) which can last for years. cGVHD is estimated to develop in approximately 40% of transplant recipients, and affects approximately 14,000 patients in the
Axatilimab is an investigational monoclonal antibody that targets colony stimulating factor-1 receptor, or CSF-1R, a cell surface protein thought to control the survival and function of monocytes and macrophages. In pre-clinical models, inhibition of signaling through the CSF-1 receptor has been shown to reduce the number of disease-mediating macrophages along with their monocyte precursors, and block the development of cutaneous and pulmonary cGVHD. Axatilimab is currently being evaluated in a Phase 1/2 clinical trial in patients with cGVHD, and has demonstrated compelling clinical activity and a well-tolerated safety profile. Syndax plans to commence a pivotal trial, AGAVE-201, by the end of 2020.
