Gedeon Richter announces today that the European Commission (EC) granted marketing authorization for BAT2206 (ustekinumab), a biosimilar – developed by Bio-Thera Solutions Inc. (“Bio-Thera”) – referencing Stelara®. This decision follows a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) on 19 June 2025. Richter will market BAT2206 in Europe under the brand name USYMRO®.

“We are pleased that Richter will further strengthen patient access to biosimilars in Europe through bringing USYMRO® to market. As a result of Bio-Thera’s success in gaining EC approval, Richter is expanding its biosimilar portfolio subsequent to the recent EC approvals of its in-house developed denosumab biosimilars” – said Dr. Erik Bogsch, Head of the Biotechnology Business Unit of Richter.

Bio-Thera and Richter entered into a license and commercialization agreement for USYMRO® (BAT2206) in October 2024. Under the terms of the agreement, Bio-Thera is responsible for the development and manufacturing of the product, and Richter obtained exclusive rights to commercialize the medicine in the EU, the UK and Switzerland and selected other countries.

 

About USYMRO® (ustekinumab)

USYMRO® is a 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 subunit from binding to the IL-12Rβ1 receptor chain of IL-12 (IL-12Rβ1/β2) and IL-23 (IL-12Rβ1/23R) receptor complexes on the surface of immune cells. IL-12 and IL-23 are involved in inflammatory and immune responses, such as natural killer cell activation, CD4+ T-cell differentiation and following relative cytokines stimulated release. Abnormal regulation of IL-12 and IL-23 have been implicated as important contributors to chronic inflammation, including psoriasis, psoriatic arthritis (PsA), and Crohn’s disease (CD). Neutralizing human IL-12 and IL-23 by USYMRO® to prevent the relevant cell signaling in the Th1 or Th17 lineages can effectively block the pathologic processes of these immune disorders.
