• The U.S. Food and Drug Administration (FDA) has accepted Bio-Thera's Biologics License Applications (BLA) for BAT2206 as an interchangeable biosimilar to reference product Stelara^®
• The European Medicines Agency (EMA) has accepted the Marketing Authorization Application (MAA) for BAT2206 as a biosimilar to reference product Stelara^®
• The BAT2206 BLA and MAA are based on a robust analytical, non-clinical and clinical data package comparing BAT2206 to the reference product Stelara^®

GUANGZHOU, China, July 24, 2024 /PRNewswire/ -- Bio-Thera Solutions Inc. (688177:SH), a commercial-stage biopharmaceutical company developing a pipeline of innovative therapies and biosimilars, today announced that the FDA has accepted the BLA for BAT2206, a proposed interchangeable biosimilar to Stelara^® (ustekinumab) seeking a commercial license in the United States of America. In addition, Bio-Thera also announced that the EMA has accepted the MAA for BAT2206 seeking a commercial license in the European Union (EU). A Biologics License Application seeking approval for BAT2206 is also currently under review by the China National Medicinal Product Administration (NMPA).

"The acceptance of both the FDA BLA and the EMA MAA for BAT2206 marks a milestone for Bio-Thera as it is the first ustekinumab biosimilar developed by a Chinese company to be submitted to the FDA or EMA for approval," said Dr. Shengfeng Li, Founder and CEO of Bio-Thera Solutions. "Bio-Thera is committed to helping patients around the world in need of affordable therapeutics like ustekinumab by developing BAT2206 for the global markets."

This BLA/MAA for BAT2206 is based on the totality of evidence comprising a comprehensive analytical, non-clinical and clinical data package. Extensive analytical characterization of the structural, physicochemical, and biological properties of BAT2206 was conducted and supports biosimilarity with the reference product. Additionally, a randomized double-blind, single-dose, three-arm, parallel group Phase 1 study compared the pharmacokinetics, safety and immunogenicity of BAT2206 with both the EU and US reference ustekinumab in healthy volunteers, while a randomized, double-blind, multi-dose, three-arm, parallel group Phase 3 study compared BAT2206 with ustekinumab to establish equivalent efficacy and comparable pharmacokinetic, safety and immunogenicity profiles, in subjects with Moderate to Severe Plaque Psoriasis.

About BAT2206 (ustekinumab)
BAT2206 is a proposed biosimilar to Stelara^® which is a human monoclonal antibody that inhibits the bioactivity of human IL-12 and IL-23 by preventing shared p40 from binding to the IL-12Rβ1 receptor protein expressed on the surface of immune cells. IL-12 and IL-23 are involved in inflammatory and immune responses, such as natural killer cell activation and CD4+ T-cell differentiation and activation. IL-12 and IL-23 have been implicated as important contributors to the chronic inflammation that is a hallmark of Crohn's disease and ulcerative colitis, among many other autoimmune diseases. In the United States, Stelara^® is a currently approved treatment for adult patients with 1) moderate to severe plaque psoriasis (PsO) who are candidates for phototherapy or systemic therapy, 2) active psoriatic arthritis (PsA), 3) moderately to severely active Crohn's disease (CD), 4) moderately to severely active ulcerative colitis.  In pediatric patients 6 years and older Stelara^® is currently approved for the treatment of 1) moderate to severe plaque psoriasis, who are candidates for phototherapy or systemic therapy and 2) active psoriatic arthritis (PsA).
