Expanded Approval of Adalimumab for UC
In September 2012, the U.S. Food and Drug Administration (FDA) approved adalimumab (Humira) to treat moderate or severe ulcerative colitis in adults with the condition. This medication also is approved, alone or in combination with other therapies, for the treatment of moderate-to-severe rheumatoid arthritis (RA), psoriasis and psoriatic arthritis, Crohn's disease, ankylosing spondylitis, and juvenile idiopathic arthritis in children over the age of 4.
Adalimumaba tumor necrosis factor (TFN) blocker administered as an injectioncan reduce the inflammation and abnormal immune system responses that cause symptoms of ulcerative colitis. It is approved for use when other medications to treat UC have not been effective, and has been show to help get ulcerative colitis symptoms under control and help keep the disease in remission. In clinical trials, about 1618 percent of patients experienced UC remission with adalimumab, and about 9 percent of these patients achieved sustained remission of symptoms.
To treat moderate-to-severe ulcerative colitis, adalimumab is usually administered as follows:
- Initial dose of 160 mg
- Second dose (2 weeks after the first) of 80 mg
- Maintenance doses of 40 mg every other week in patients who experience clinical remission by 8 weeks of treatment
Side effects of Humira include injection site reactions (redness, itching, swelling, bruising), rash, headache, nausea and upper respiratory infections. TFN blockers, which can impair the immune system’s ability to fight infections, increase the risk for serious infections, including tuberculosis (TB), as well as certain types of cancer.
