FDA Approves BMS Orencia for Graft Versus Host Disease

Share

FDA has approved a new indication for Bristol-Myers Squibb’s Orencia (abatacept) to be used in combination with certain immunosuppressants to prevent acute graft versus host disease. An agency announcement says the disease occurs when donor bone marrow or stem cells attack the graft recipient.

Orencia may be used in adults and pediatric patients age 2 and older undergoing hematopoietic stem cell transplantation, the notice says. It is the first FDA approval for acute graft versus host disease prevention and incorporated real-world evidence as one component of the determination of clinical effectiveness.

FDA says the safety and efficacy of Orencia in combination with immunosuppressant therapy in patients age 6 and older who underwent stem cell transplantation from a matched or mismatched unrelated donor were evaluated in two studies. Additional evidence of effectiveness was provided by GVHD-2, a registry-based clinical study conducted using real-world data from the Center for International Blood and Marrow Transplant Research in patients who underwent stem cell transplantation from a mismatched unrelated donor.

Orencia received FDA Breakthrough, Orphan Drug, and Priority Review designations for this indication. The development of the drug was partially supported by the agency’s Orphan Products Grants Program.

The notice says Orencia was originally approved by FDA in 2005 to treat adult rheumatoid arthritis. It also is approved to treat polyarticular juvenile idiopathic arthritis and adult psoriatic arthritis.

The review of Orencia for this indication was conducted under Project Orbis, an initiative in the FDA Oncology Center of Excellence that provides a framework for the concurrent submission and review of oncology drugs among international partners. For this review, FDA collaborated with Health Canada, Swissmedic, and the Israeli Ministry of Health.
