Avonex is an interferon, a type of protein produced by the body to help protect you against infections. Avonex is similar to the interferons produced by your body. Avonex has been authorized by the US Food and Drug Administration, Health Canada, and by 69 other countries for the treatment of multiple sclerosis (MS), a disease of the immune system that damages the brain and spinal cord. Avonex may be useful in the treatment of ulcerative colitis (UC), because UC is also a disease of the immune system.

The purpose of this study is to determine if Avonex, a drug currently used to treat MS, can reduce or eliminate the symptoms of your type of UC (bleeding, abdominal pain, diarrhea, constipation, irregular bowel movements, and other symptoms) and reduce the inflammation or heal the inside of the colon that is affected by UC. This study will also determine the side effects of Avonex treatment and how well Avonex treatment is tolerated by patients with UC.
