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, 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. Switching between GP2015 and reference etanercept had no impact on clinical efficacy, tolerability or immunogenicity. The role of reference etanercept in the management of inflammatory autoimmune conditions is well established and GP2015 provides an effective biosimilar alternative for patients requiring etanercept therapy.
