Formycon presents clinical data on ustekinumab biosimilar FYB202 at the ECCO Congress in Berlin

Planegg-Martinsried, Germany – Formycon AG (FSE: FYB, Prime Standard, “Formycon”) will present an overview of the comparative data of the ustekinumab biosimilar FYB202 at this year’s Congress of the European Crohn’s and Colitis Organisation (ECCO), taking place in Berlin, Germany, from February 19 to 22, 2025. The poster presentation summarizes the clinical phase I and phase III study results and is complemented by advanced analytical laboratory data demonstrating the comparability of FYB202 with the reference product Stelara ®1 . Using a comprehensive set of analytical methods, the relevant quality characteristics of FYB202 were first examined and its functional comparability with the reference product was assessed in terms of the main mechanism of action using IL-12 and IL-23 binding tests and bioassays. FYB202 was found to be analytically comparable to the reference ustekinumab with respect to physicochemical and biological properties, including structure, function, purity and potency. The therapeutic equivalence of FYB202 was demonstrated in a Phase I pharmacokinetics (PK) study in 491 healthy volunteers and in a Phase III efficacy study in 392 patients with moderate to severe plaque psoriasis. Based on a totality of evidence approach, these results allow for extrapolation to other approved indications of the reference drug and confirm that FYB202 has a comparable clinical performance to Stelara ® in all indications, making it a safe and highly effective alternative for patients treated with ustekinumab. Presentation details: Session: Guided poster session, February 21, 2025, 12:40 pm – 1:40 pm CET Poster-ID: P0879 Title: The Totality of Evidence for FYB202 – an EU-approved and US-licensed Biosimilar to Reference Ustekinumab Room: Poster Exhibition Area Date: February 19-22, 2025 FYB202 is an interleukin inhibitor that can be used in dermatology to treat psoriasis and in gastroenterology to treat chronic inflammatory bowel disease. The biosimilar received marketing authorization from the EMA and the FDA in September 2024, and from Health Canada and the UK’s MHRA in January 2025. 1) Stelara ® is a registered trademark of Johnson & Johnson About Formycon: Formycon AG (FSE: FYB) is a leading, independent developer of high-quality biosimilars, follow-on products of biopharmaceutical medicines.

Further information can be found at: https://www.formycon.com/ About Biosimilars: Since their introduction in the 1980s, biopharmaceutical drugs have revolutionized the treatment of serious and chronic diseases. By 2032, many of these drugs will lose their patent protection – including 45 blockbusters with an estimated total annual global turnover of more than 200 billion US dollars. Biosimilars are successor products to biopharmaceutical drugs for which market exclusivity has expired. They are approved in highly regulated markets such as the EU, the USA, Canada, Japan and Australia in accordance with strict regulatory procedures. Biosimilars create competition and thus give more patients access to biopharmaceutical therapies. At the same time, they reduce costs for healthcare providers. Global sales of biosimilars currently amount to around 21 billion US dollars. Analysts assume that sales could rise to over 74 billion US dollars by 2030.
