A comparative study of PF-06438179/GP1111 (an infliximab biosimilar) and reference infliximab in patients with moderate to severe active rheumatoid arthritis: A subgroup analysis.

ABSTRACT:

Aim

PF-06438179/GP1111 (PF-SZ-IFX) is a biosimilar of reference infliximab (Remicade^® ). This analysis compared the efficacy of PF-SZ-IFX and reference infliximab sourced from the European Union (IFX-EU) in patient subgroups from a randomized, comparative study of PF-SZ-IFX versus IFX-EU.

Methods

Patients with rheumatoid arthritis were randomized 1:1 to PF-SZ-IFX (n = 324) or IFX-EU (n = 326); study drug (3 mg/kg) was administered intravenously at weeks 0, 2, and 6, then every 8 weeks thereafter. Subgroup analyses of efficacy endpoints such as American College of Rheumatology criteria for ≥20% clinical improvement (ACR20), change in high-sensitivity C-reactive protein (hs-CRP), and change in Disease Activity Score in 28 joints, four components based on hs-CRP (DAS
