Hi KKelly; Here is what I found out about Orencia (Abatacept). Orencia (generic: abatacept) is the first T-cell co-stimulation modulator approved for the treatment of rheumatoid arthritis (RA). It is a fully human soluble fusion protein that works by selectively modulating a co-stimulatory signal which is required for full T-cell activation. Activated T cells play a central role in the inflammatory process leading to the joint inflammation. The cytokines secreted by activated T cells are thought to both initiate and propagate the immunologically driven inflammation associated with RA.
In patients with Lupus, 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 SLE and 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.
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 Lupus and Arthritis. Abatacept slows the damage to bones and cartilage and relieves the symptoms.
Abatacept was approved by the FDA in December, 2005. (Abatacept) Orencia is a 30-minute intravenous infusion.
