CAMBRIDGE, Mass. and GUANGZHOU, China, June 03, 2022 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) and Bio-Thera Solutions, Ltd. (688177.SH) today presented positive Phase 3 data for BIIB800 (BAT1806), a biosimilar candidate referencing ACTEMRA®/ROACTEMRA® (tocilizumab), anti-interleukin-6 receptor monoclonal antibody, at the Annual European Congress of Rheumatology (EULAR 2022).
Data from the Phase 3 comparative clinical trial demonstrated that the investigational biosimilar candidate BIIB800 has equivalent efficacy and comparable safety and immunogenicity profile to the reference tocilizumab product. The double-blind 52-week Phase 3 study randomized 621 patients with moderate to severe rheumatoid arthritis to receive either BIIB800 or the reference tocilizumab administered intravenously every 4 weeks at a dose of 8 mg/kg for the first 24 weeks.
The primary endpoints were ACR20* response at week 12 and week 24. The ACR20 response rates in the BIIB800 group and the reference tocilizumab group were 68.97% vs. 64.82% at week 12 and 69.89% vs. 67.94% at week 24. The estimated difference between the two groups were within the pre-defined equivalence margins (4.15% (95% CI - 3.63 to 11.93) at week 12 and 1.94% (90% CI -4.04 to 7.92; 95% CI -5.18 to 9.07) at week 24. The treatment groups were comparable in terms of serum trough tocilizumab levels, incidence of treatment emergent adverse events and anti-drug antibody positivity and hence demonstrated comparable pharmacokinetics, safety and immunogenicity.
“At Biogen, we are advancing development of pipeline of biosimilar candidates like BIIB800 with the goal of optimizing the management of chronic immune mediated inflammatory diseases and helping more patients and healthcare systems across the world to benefit from biologics,” said Mourad Farouk Rezk, MD, Head of Global Medical and Development Biosimilars at Biogen. “Biogen is committed to the scientific progress in the treatment of various immunologic conditions that accelerate our ability to tackle these complex diseases.”
“Bio-Thera is proud to have the Phase 3 data for BIIB800 (BAT1806) presented to doctors, researchers, and patients at the EULAR conference. These results highlight the expertise and commitment of Bio-Thera to develop the highest quality biosimilars of important therapeutic products to expand patient access around the globe,” said Dr. Shengfeng Li, CEO of Bio-Thera Solutions.
The abstract is available online at the website of EULAR 2022 which has been held both virtually through the Congress platform and on-site in Copenhagen, Denmark between June 1-4, 2022.
ACTEMRA®/ ROACTEMRA® is indicated for moderate to severe rheumatoid arthritis in adults as well as juvenile idiopathic polyarthritis, systemic juvenile idiopathic arthritis, giant cell arteritis, chimeric antigen receptor (CAR) T cell-induced cytokine release syndrome, systemic sclerosis-associated interstitial lung disease (approved by FDA) and coronavirus disease 2019 (COVID-19) (under emergency use authorization by FDA), and severe COVID-19 (approved by EMA).
On April 8th, 2021, Biogen and Bio-Thera Solutions, Ltd. entered into a commercialization and license agreement to develop, manufacture and commercialize BIIB800 (BAT1806). Biogen has exclusive regulatory, manufacturing and commercial rights to BIIB800 in all countries excluding China (including Hong Kong, Macau and Taiwan).
About the BIIB800 Phase 3 Trial
The BIIB800 clinical trial was a global, randomized, multicenter, double-blind, parallel-group, Phase 3 active-control study designed to evaluate the efficacy, safety, PK and immunogenicity of BIIB800 compared to ACTEMRA®/ROACTEMRA® in 621 patients with moderate to severe rheumatoid arthritis with inadequate response to methotrexate. Out of the 621 total patients enrolled in the Phase 3 Trial, 253 (40.7%) patients were from China and 368 (59.3%) patients were from Europe.
