Positive data from extended Phase I pharmacokinetics study complete clinical development program Phase I and phase III clinical trial program demonstrated comparable safety and efficacy of FYB202 and the reference drug Stelara® * Submission for regulatory approval in Europe and the U.S. planned for the third quarter of 2023 Munich – Formycon AG (ISIN: DE000A1EWVY8/ WKN: A1EWVY) today announced the successful conclusion of the extended Phase I clinical study comparing the pharmacokinetics of FYB202 and the reference drug Stelara®. As early as August 2022, the primary endpoint was achieved in the randomized, double-blind, multicenter Phase III study (VESPUCCI), demonstrating the comparable efficacy of FYB202 and the reference drug in patients with moderate-to-severe psoriasis vulgaris (plaque psoriasis). The positive results of the Phase I pharmacokinetics study successfully conclude the clinical development program. FYB202 was bioequivalent to the reference drug Stelara® sourced in the EU as well as in the U.S. for all primary endpoint parameters. European and U.S. regulatory submissions are still planned for the third quarter of 2023. Provided successful approval by the respective health agencies, Fresenius Kabi will commercialize FYB202 in key global markets. The active ingredient ustekinumab is a human monoclonal antibody that targets the cytokines interleukin-12 and interleukin-23. Since 2009, the originator medicine has been used to treat various severe inflammatory conditions such as moderate-to-severe psoriasis as well as psoriatic arthritis. Its approved indications were expanded to chronic inflammatory bowel diseases like treatment of Crohn’s disease (2016) and ulcerative colitis (2019). Stelara® achieved a global sales volume of USD 9.7 billion in 2022. [1] Formycon CEO Dr. Stefan Glombitza comments: “The successful conclusion of the development phase of our ustekinumab biosimilar candidate marks a very important milestone for Formycon and highlights the significant progress in our biosimilar pipeline. We are confident that we will provide the authorities with a convincing data package this fall. With FYB202, we can contribute significantly to the treatment options in the growing market segment of inflammatory diseases.” * Stelara® is a registered Trademark of Johnson & Johnson [1] Johnson & Johnson top pharmaceutical products by sales 2022 | Statista.

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.
