T Cell Costimulation Modulator (Abatacept)
Abatacept (
Orencia®) is a new biologic response modifier used to treat moderate to severe rheumatoid
arthritis in people who have not adequately responded to other medications.
Orencia works by inhibiting T cells. T cells are a type of white blood cell (leukocytes) that play an important role in the immune system. Orencia seems to prevent T cells from being active and multiplying too much. It is given as a monthly injection.
