For which conditions is this drug approved? Orencia is approved for use in adults with moderate to severe rheumatoid arthritis (RA). This includes patients who have tried other medicines for RA that have not worked well enough. Orencia can be used alone or with other RA treatments, except for RA treatments known as tumor necrosis factor (TNF) antagonists. Orencia can also be used for the treatment children and teenagers, six years of age and older, with moderate to severe polyarticular juvenile idiopathic arthritis (JIA). In patients with JIA, Orencia can be used alone or with methotrexate.
What is the mechanism of action? In patients with RA, Orencia works by suppressing the immune system to prevent it from damaging tissues and joints. The immune system helps protect the body from harmful substances such as infectious agents and bacteria. In people with RA, however, the immune system attacks and destroys normal tissue—namely, the tissue around the joints. This leads to inflammation and damage to the cartilage and bone and causes pain. Specifically, Orencia blocks the action of immune cells called T-lymphocytes to stop these cells from attacking normal tissue.
How is Orencia typically given (administered)? Orencia is given as an intravenous (IV) infusion. Each infusion takes about 30 minutes. After you receive your first dose, you’ll receive a second dose two weeks later and then every four weeks after that. You can also receive Orencia as an injection under your skin. Your doctor may decide that it’s safe for you to give yourself the injection or have a caregiver give them. Your doctor will show you or your caregiver how to give the injections.
How are patients typically monitored? During treatment with Orencia, your doctor will check you regularly for the following:
- Hypersensitivity and severe allergic reaction—including sudden, widespread, and potentially life-threatening reaction
