Bevacizumab biosimilar(Bio-Thera Solutions, Ltd.)

Comparable clinical efficacy and safety in Treatment Period 2 (TP2, Week 24-48) is maintained after switch from reference tocilizumab to TOFIDENCE (BAT1806/BIIB800) Phase 3 clinical data in totality demonstrates biosimilarity between TOFIDENCE (BAT1806/BIIB800) and reference tocilizumab before and after switching.1,2 GUANGZHOU, China, Sept. 11, 2024 /PRNewswire/ -- Bio-Thera Solutions, Ltd. today announced, in collaboration with Biogen, the publication in the journal Arthritis Research & Therapy of results from Treatment Period 2 (TP2; study weeks 24-48) of a Phase 3 clinical study evaluating BAT1806/BIIB800, an approved biosimilar to Actemra®/RoActemra®3 (tocilizumab). BAT1806/BIIB800 is currently commercialized under the brand name TOFIDENCE™4. In the Phase 3, multicenter, multiregional, double-blind, active-controlled, clinical equivalence study, participants with active rheumatoid arthritis (RA) despite treatment with methotrexate were randomized (1:1:2) to intravenous (iv) administration of 8 mg/kg reference tocilizumab (TCZ) every 4 weeks to week 48 (TCZ group), or TCZ to week 24 followed by BAT1806/BIIB800 to week 48 (TCZ to BAT1806/BIIB800 group), or BAT1806/BIIB800 to week 48 (BAT1806/BIIB800 group)1,2. Efficacy in TP2 of the study was evaluated using American College of Rheumatology (ACR) response criteria (ACR20/50/70) and change from baseline in Disease Activity Score on 28 joints (DAS28)2. Pharmacokinetics, safety, and immunogenicity were also evaluated. TP2 analysis also assessed the possible impact of a single treatment switch from TCZ to BAT1806/BIIB800 after week 24, reflecting clinical practice where multiple treatment switches occur. Results from TP2 of the Phase 3 study demonstrated maintenance of comparable clinical efficacy, safety, immunogenicity and PK following switch to BAT1806/BIIB800 from TCZ, in patients with Rheumatoid Arthritis and an inadequate response to methotrexate. "We are pleased to publish the switching data of TOFIDENCE (BAT1806/BIIB800) from reference tocilizumab that strongly supports its biosimilarity to tocilizumab for a long-term period in treating patients with active rheumatoid arthritis and an inadequate response to MTX," said Dr Xiaolei Yang, Executive Medical Director for Rheumatology and Immunology at Bio-Thera. "We hope the study results help allay any concerns over safety and efficacy of TOFIDENCE (BAT1806/BIIB800) for use in patients who were previously treated with reference product." Bio-Thera Solutions, Ltd. and Biogen entered into a commercialization and license agreement to develop, manufacture and commercialize TOFIDENCE (BAT1806/BIIB800) on April 8th, 2021. Biogen has exclusive regulatory, manufacturing and commercial rights to TOFIDENCE (BAT1806/BIIB800) in all countries excluding China (including Hong Kong, Macau and Taiwan). BAT1806/BIIB800 TP2 Analysis Of 621 randomized participants, 577 (92.9%) completed Treatment Period 1 (TP1, Week 0-24) and entered TP2 (TCZ: N = 145 [93.5%]; TCZ to BAT1806/BIIB800: N = 142 [92.2%]; BAT1806/BIIB800: N = 290 [92.9%])1,2. Proportions of ACR20 responders were similar between treatment groups throughout TP2 (87.8%, 90.3%, and 90.4%, respectively, at week 48), as were proportions of ACR50 and ACR70 responders, and reduction in DAS28. Drug trough levels and antidrug antibody incidences were comparable between the treatment groups. Adverse events were balanced across the treatment groups and no fatal events were reported. In TP2, efficacy, safety, immunogenicity, and pharmacokinetic profiles were comparable between the TCZ, TCZ to BAT1806/BIIB800, and BAT1806/BIIB800 groups. These longer-term findings reinforce the results reported for TP1 and further support biosimilarity.
