Etanercept MOA: Overview

Etanercept is indicated for the treatment of moderately to severely active rheumatoid arthritis in adults and in chronic moderate to severe plaque psoriasis in patients 4 years of age and older. It is also used to manage signs and symptoms of polyarticular idiopathic arthritis in those aged 2 years and older.

Etanercept Mechanism of Action

Etanercept is also used to manage the symptoms of psoriatic arthritis and ankylosing spondylitis. 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. It is used to treat or manage a variety of inflammatory conditions including rheumatoid arthritis (RA), ankylosing spondylitis (AS), and juvenile idiopathic poly-articular arthritis (JIA).

Etanercept Biosimilars Guidelines: Marketed Drugs

GP 2015: Sandoz
GP2015 is the second biosimilar of the reference p75 TNF receptor-Fc fusion protein etanercept. It is approved for use in all indications for which reference etanercept is approved, including rheumatoid arthritis, juvenile idiopathic arthritis, and psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, plaque psoriasis and paediatric plaque psoriasis. GP2015 has similar physiochemical and pharmacodynamic properties to those of reference etanercept, and the pharmacokinetic biosimilarity of the agents has been shown in healthy volunteers. GP2015 demonstrated clinical efficacy equivalent to that of reference etanercept in patients with moderate-to-severe plaque psoriasis; the tolerability, safety and immunogenicity profiles of the two agents were also generally similar.

Etanercept Biosimilars Companies: Emerging Drugs

CHS-0214: Coherus BioSciences
​CHS-0214 is being developed in phase III stage of development. Coherus BioSciences (CHRS) and Baxalta (BXLT) announced that CHS-0214, a proposed biosimilar of Enbrel, met its primary endpoint in a confirmatory, double-blind, randomized, and controlled, two-part clinical study. This ongoing study is evaluating the efficacy and safety of CHS-0214 compared to Enbrel in patients with moderate-to-severe rheumatoid arthritis that is inadequately controlled with methotrexate alone
