Sandoz presents new long-term and switching data for biosimilars Zessly® (infliximab) and Erelzi® (etanercept) in rheumatoid arthritis

In This Article:

  • Zessly® (infliximab) matched the reference medicine in terms of safety and efficacy at 54 weeks, even in patients who switched from the reference medicine to Zessly[1]

  • Switching from the reference medicine to Erelzi® (etanercept) did not impact efficacy and safety in patients with moderate to severe rheumatoid arthritis at 48 weeks[2]

  • Nearly 320 million people in Europe are expected to have limited access to disease-modifying anti-rheumatic medicines, underscoring the value of Zessly and Erelzi[3]

Holzkirchen, June 15, 2018 - Sandoz, a Novartis division and the pioneer and global leader in biosimilars, today announced the presentation of two long-term, Phase III studies: one each for biosimilar Zessly® (infliximab)[4],[5] and biosimilar Erelzi® (etanercept).[6],[7]

Research from the 54-week REFLECTIONS B537-02 study of Zessly and the 48-week EQUIRA study of Erelzi showed that each biosimilar matched its reference biologic in terms of safety, efficacy and quality, reinforcing previously-presented findings.[1],[2],[8].[9] The research also indicated that switching from the reference medicine to the biosimilar did not affect safety, efficacy or immunogenicity.[1],[2] Both studies are being presented at the Annual European Congress of Rheumatology (EULAR) in Amsterdam.

"We are very pleased with these data, which reinforce what well over 10 years of science and real-world evidence in Europe have shown - that biosimilars match their reference medicines in terms of safety, efficacy and quality," said Mark Levick, MD, PhD, Global Head of Development, Biopharmaceuticals, Sandoz. "It is our hope that these studies will help healthcare providers and patients have confidence that switching to Zessly or Erelzi will continue to deliver the benefits they are receiving from their existing treatment."

About the Zessly® (infliximab) Research (Poster FRI0137; 15 June, 11:45 - 13:30 CET) "Efficacy, Safety and Immunogenicity from Week 30 to Week 54 in a Randomised, Double-Blind, Phase III Study Comparing an Infliximab Biosimilar (PF-06438179/GP1111) with Reference Infliximab"

REFLECTIONS B537-02 is a Phase III, double-blind, parallel-group, confirmatory study of Sandoz biosimilar Zessly (infliximab) versus reference Remicade®* (infliximab) in combination with methotrexate in 650 biologic-naïve, adult patients with moderately to severely active rheumatoid arthritis who had an inadequate response to methotrexate therapy alone.[8]

The study met its primary endpoint, a >=20% improvement in American College of Rheumatology (ACR) response (ACR 20) at Week 14. The research demonstrated that there were no clinically-meaningful differences from 30 to 54 weeks in terms of safety, efficacy and immunogenicity between patients with rheumatoid arthritis remaining on Sandoz infliximab and reference infliximab. The same results were found when patients on reference infliximab were blindly re-randomized to switch to Sandoz infliximab or remained on reference therapy.[1]
