GENERIC NAME: abatacept
BRAND NAME: Orencia
DRUG CLASS AND MECHANISM: Abatacept is an injectable, synthetic (man-made) protein produced by recombinant DNA technology that is used for treating rheumatoid arthritis. It is an immunesuppressant, a drug that suppresses the immune system that is similar to alefacept (Amevive) and belatacept (Nulojix). The immune system is responsible for protecting the body against foreign invaders, for example, infectious agents such as bacteria. In patients with rheumatoid arthritis, however, the immune system attacks and destroys normal tissue in and around the joints, causing pain, inflammation and damage to bone and cartilage. T-lymphocytes are important cells of the immune system. Patients with rheumatoid arthritis have increased numbers of T-lymphocytes within the joints that are inflamed. The T-lymphocytes are "activated," that is, they multiply and release chemicals that promote the destruction of tissues surrounding the joints and cause the signs and symptoms of rheumatoid arthritis. Abatacept acts like an antibody and attaches to a protein on the surface of T-lymphocytes. By attaching to the protein, abatacept prevents the activation of the T-lymphocytes and blocks both the production of new T-lymphocytes and the production of the chemicals that destroy tissue and cause the symptoms and signs of arthritis. Abatacept relieves the symptoms and signs of arthritis and is a disease-modifying antirheumatic drug (DMARD) because it slows the damage to bones and cartilage and improves physical function. Abatacept was approved by the FDA in December 2005.
