11 DESCRIPTION Adalimumab-atto is a tumor necrosis factor blocker. Adalimumab-atto is a recombinant human IgG1 monoclonal antibody with human derived heavy and light chain variable regions and human IgG1:k constant regions. Adalimumab-atto is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary (CHO)) expression system and is purified by a process that includes...
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Adalimumab products bind specifically to TNF-alpha and block its interaction with the p55 and p75 cell surface TNF receptors. Adalimumab products also lyse surface TNF expressing cells in vitro in the presence of complement. Adalimumab products do not bind or inactivate lymphotoxin (TNF-beta). TNF is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Elevated concentrations of TNF are found in the synovial fluid of patients with RA, JIA, PsA, and AS and play an important role in both the pathologic inflammation and the joint destruction that are hallmarks of these diseases. Increased concentrations of TNF are also found in psoriasis plaques.

- 7 DRUG INTERACTIONS Abatacept: Increased risk of serious infection. ( 5.1 , 5.11 , 7.2 ) Anakinra: Increased risk of serious infection. ( 5.1 , 5.7 , 7.2 ) Live vaccines: Avoid use with AMJEVITA. ( 5.10 , 7.3 ) 7.1 Methotrexate Adalimumab has been studied in rheumatoid arthritis (RA) patients taking concomitant methotrexate (MTX). Although MTX reduced the apparent clearance of adalimumab, the data do not suggest the need for dose adjustment of either AMJEVITA or MTX [see Clinical Pharmacology (12.3) ] . 7.
