Dimeric fusion protein consisting of the extracellular ligand-binding portion of the human 75 kilodalton (p75) tumor necrosis factor receptor (TNFR) linked to the Fc portion of human IgG1. The Fc component of etanercept contains the CH2 domain, the CH3 domain and hinge region, but not the CH1 domain of IgG1. Etanercept is produced by recombinant DNA technology in a Chinese hamster ovary (CHO) mammalian cell expression system. It consists of 934 amino acids.

Pharmacology

Indication

Etanercept is indicated for the treatment of moderately to severely active rheumatoid arthritis in adults and chronic moderate to severe plaque psoriasis in adults. It is also used to manage signs and symptoms of polyarticular idiopathic arthritis in those aged 4 to 17 after insufficient response to one or more disease-modifying anti-rheumatic drugs. Etanercept is also used to improve psoriatic arthritis and ankylosing spondylitis.

Associated Conditions

Pharmacodynamics

Etanercept binds specifically to tumor necrosis factor (TNF) and thereby modulates biological processes that are induced or regulated by TNF. Such processes or molecules affected include the level of adhesion molecules expressed, as well as serum levels of cytokines and matrix metalloproteinase-3, also known as stromelysin. In animal models, etanarcept has been demonstrated to affect inflammation, such as in murine collagen-induced arthritis.

Mechanism of action

There are two distinct receptors for TNF (TNFRs), a 55 kilodalton protein (p55) and a 75 kilodalton protein (p75). The biological activity of TNF is dependent upon binding to either cell surface receptor (p75 or p55). Etanercept is a dimeric soluble form of the p75 TNF receptor that can bind to two TNF molecules, thereby effectively removing them from circulation.

TNF is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Increased levels of TNF are found in tissues and fluids of those with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis (AS), and plaque psoriasis.
