  • The clinical comparative study met its primary endpoint and showed similar efficacy and comparable safety profile in patients with moderate to severe plaque psoriasis


GUANGZHOU, China, November 29, 2023 /PRNewswire/ -- Bio-Thera Solutions, Ltd. (688177:SH), a commercial-stage biopharmaceutical company developing a pipeline of biosimilars and innovative assets, today announced results from the Phase 3 study of BAT2206, a proposed biosimilar referencing Stelara® (ustekinumab). The primary endpoint of this study was improvement from baseline in Psoriasis Area and Severity Index (PASI) score to Week 12, demonstrating BAT2206 is highly similar with Stelara® in patients with moderate to severe plaque psoriasis.


In the US, Stelara® is currently approved for the treatment of patients 6 years or older with active psoriatic arthritis (PsA), the treatment of patients 6 years or older with moderate to severe plaque psoriasis (Ps) who are candidates for phototherapy or systemic therapy, the treatment of moderately to severely active Crohn’s disease (CD) in adults, and the treatment of moderately to severely active ulcerative colitis (UC) in adults.


The BAT2206 clinical trial was a global, multicenter, randomized, double-blind, parallel-arm, Phase 3 study designed to compare the efficacy, safety, immunogenicity and PK of BAT2206 with Stelara® in 556 patients with moderate to severe plaque psoriasis. More information regarding the BAT2206 Phase 3 clinical trial, including inclusion and exclusion criteria and primary and secondary outcome measures, can be found here:  Results of the study will be presented in a future medical meeting or publication.


“We are pleased to report on our fourth proposed biosimilar with positive Phase 3 study results. These results demonstrate the potential of our proposed ustekinumab biosimilar to be a safe and effective treatment,” said Shengfeng Li, Ph.D., chief executive officer at Bio-Thera Solutions. “Bio-Thera is committed to increasing patient access to innovative medicines through the development of high-quality biosimilars.”


“I’m very pleased to have participated in the successful global Phase 3 study of BAT2206,” commented professor Min Zheng, leading investigator for global phase 3 study of BAT2206.  “BAT2206 will provide a new affordable treatment option for global patients in need. Congratulations to Bio-Thera Solutions."


Bio-Thera entered into a commercialization and license agreement with Hikma for BAT2206 in August 2021. Developed by Bio-Thera, BAT2206 will be commercialized by Hikma in the United States of America. 



About BAT2206 (ustekinumab)

BAT2206 is a proposed biosimilar to Janssen’s 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.
