Aflibercept Biosimilar Candidate FYB203 shows comparable efficacy to the reference product Eylea®1 in Phase III Study

MAGELLAN-AMD study demonstrates the comparable efficacy of FYB203 to the reference product Eylea ® in patients with neovascular age-related macular degeneration (nAMD) Primary efficacy endpoint for submission to the U.S. Food and Drug Administration (FDA) achieved in global phase III study Second successful clinical development program in the field of ophthalmological biosimilars highlights Formycon’s strong position in this area Munich – Formycon AG (ISIN: DE000A1EWVY8/ WKN: A1EWVY) today published positive preliminary efficacy and safety data from MAGELLAN-AMD Phase III clinical trial for FYB203, its proposed biosimilar to Eylea ® . The FDA-specific interim analysis of the randomized, double-blind, multi-center phase III study met the primary efficacy endpoint, demonstrating comparable efficacy between FYB203 and the reference medicine Eylea ® in patients with neovascular age-related macular degeneration (nAMD). The primary endpoint of the comparative global Phase III trial measures the change in best corrected visual acuity after eight weeks from baseline. The values obtained for FYB203 and the reference product are within the relevant equivalence limits. In addition, to date, the study was conducted without any clinically relevant differences in terms of safety and immunogenicity. Following the approval and market launch of the ophthalmological biosimilar for Lucentis® (FYB201 marketed as Ongavia® 2 (UK), Ranivisio® 3 (EU), and Cimerli TM4 (US)), Formycon is now announcing, with FYB203, another successful development in the field of ophthalmology, thereby highlighting its strong position in this area. Neovascular age-related macular degeneration (nAMD) is caused by the excessive growth of blood vessels in the retina. The active ingredient aflibercept inhibits the vascular endothelial growth factor (VEGF), which is responsible for the excessive formation of blood vessels in the retina, which leads to a progressive loss of vision. In industrialized countries, AMD is the most common cause of severe visual impairment or blindness. According to estimates, up to 77 million Europeans will be affected by 2050. [i] Eylea® is currently the top-selling drug in the field of age-related eye disease and in 2021 achieved revenues of around US$ 9 billion. Recently, Klinge Biopharma GmbH, licensee and exclusive holder of the worldwide commercialization rights of FYB203, had entered into a binding term sheet for the exclusive commercialization of FYB203 in the United States of America with Coherus BioSciences, Inc. Formycon’s CSO, Dr. Andreas Seidl, comments on the successful phase III study as follows: “We are delighted that our second project in the field of ophthalmology was able to impress in the clinical phase III MAGELLAN-AMD study. Given the extensive experience from FYB201, we are confident that we will also be able to make a high-quality and cost-effective biosimilar available with FYB203, thereby further expanding our strong position in the field of biosimilar development.” [i] Li JQ, Welchowski T, Schmid M, et al.

The company focuses on therapies in ophthalmology, immunology, immuno-oncology and other key disease areas, covering almost the entire value chain from technical development through clinical trials to approval by the regulatory authorities. For commercialization of its biosimilars, Formycon relies on strong, well-trusted and long-term partnerships worldwide. With FYB201/ranibizumab and FYB202/ustekinumab, Formycon already has two biosimilars on the market in Europe and the USA. A third biosimilar, FYB203/aflibercept, has been approved by the FDA, EMA, and MHRA; FYB202 is also approved in Canada. Another four biosimilar candidates are currently in development. With its biosimilars, Formycon is making an important contribution to providing as many patients as possible with access to highly effective and affordable medicines. Formycon AG, headquartered in Munich, is listed in the Prime Standard of the Frankfurt Stock Exchange: FYB / ISIN: DE000A1EWVY8 / WKN: A1EWVY and is part of the SDAX and TecDAX selection indices. 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.
