Adalimumab is a monoclonal anti-tumor necrosis factor alpha antibody used in the treatment of a wide variety of inflammatory conditions such as rheumatoid arthritis, Crohn's disease, and ankylosing spondylitis.
Adalimumab binds with specificity to tumor necrosis factor-alpha (TNF-alpha) and inhibits its interaction with the p55 and p75 cell surface TNF receptors. Adalimumab also lyses surface tumor necrosis factor expressing cells in vitro when in the presence of complement. Adalimumab does not bind or inactivate lymphotoxin (Tumor necrosis factor-beta). TNF is a naturally occurring cytokine that plays a role in normal inflammatory and immune responses. Increased levels of TNF are found in the joint synovial fluid of rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis patients, and play an imperative role in pathologic inflammation and joint destruction that are major complications of these diseases. Increased levels of TNF are also measured in psoriasis plaques. In plaque psoriasis, treatment with adalimumab may decrease the epidermal thickness and inflammatory cell infiltration. The relationship between these pharmacodynamics and the mechanism(s) by which adalimumab achieves its clinical effects is not known. Additionally, adalimumab alters biological responses that are induced/regulated by TNF, including changes in the levels of adhesion molecules responsible for leukocyte migration during inflammation (ELAM-1, VCAM-1, and ICAM-1 with an IC50 of 1-2 X 10-10M).
Adalimumab is indicated for the following conditions: Adalimumab has also been used off-label to treat Pyoderma gangrenosum.
