Kineret®

Class: Biologic Therapy

Generic Name: anakinra

Trade Name: Kineret®

How is this drug used? Kineret is approved for adults to reduce the signs and symptoms and slow the damage of moderate to severe rheumatoid arthritis (RA) when one or more other drugs have not worked, and to treat people with Neonatal-Onset Multisystem Inflammatory Disease (NOMID).

What is the mechanism of action? Kineret is an immunosuppressant that 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, Kineret blocks the action of a certain protein to decrease the proliferation of rapidly dividing cells that cause inflammation.

How is Kineret given (administered)? Kineret is administered daily by subcutaneous injection at approximately the same time every day. Dosage frequency may be altered if you have kidney problems. Call your healthcare provider if you miss a dose to be informed on when you will administer your next injection.

How are patients monitored? Patients should have complete blood counts (CBC), including platelet counts, before treatment with Kineret, then monthly for three months, then every three months thereafter for one year.
