Bad Homburg, Germany; September 30, 2024 - Fresenius Kabi, an operating company of Fresenius, specializing in biopharmaceuticals, clinical nutrition, medical technologies, and I.V. generic drugs for critical and chronic conditions, and Formycon AG, a leading, independent developer of high-quality biosimilars, announced today that the United States (U.S.) Food and Drug Administration (FDA) has approved OtulfiTM (ustekinumab-aauz), its ustekinumab biosimilar referencing Stelara® ** (ustekinumab). OtulfiTM is approved for the treatment of Crohn’s disease, ulcerative colitis, moderate to severe plaque psoriasis and active psoriatic arthritis. Fresenius Kabi is further continuing its momentum, striving at expanding its strong Biopharma platform, which is a substantial cornerstone of #FutureFresenius.

“The FDA approval of OtulfiTM, Fresenius Kabi’s fourth biosimilar product in the U.S. market, is an important milestone on our pathway to consistently broadening our biopharma portfolio in the U.S. and worldwide. In line with our Vision 2026 growth strategy, we are fully committed to becoming a significant player in the biopharma field and offering essential treatment options for patients globally,” said Dr. Sang-Jin Pak, President Biopharma and member of the Fresenius Kabi Management Board.

In February 2023, Fresenius Kabi and Formycon entered into a global commercialization partnership for the ustekinumab biosimilar candidate covering key global markets.

Ustekinumab is a human monoclonal antibody that targets the cytokines interleukin-12 and interleukin-23 which play an important role in inflammatory and immune responses. The FDA approval of OtulfiTM (ustekinumab-aauz) is based on a thorough evaluation of a comprehensive data package including analytical, pre-clinical, clinical and manufacturing data. OtulfiTM demonstrated comparable efficacy, safety, pharmacokinetics and immunogenicity to the reference drug Stelara® in patients with moderate to severe psoriasis vulgaris (plaque psoriasis). OtulfiTM was approved for both subcutaneous and intravenous formulations which will offer a comprehensive, alternative treatment solution for health care professionals and patients treated with ustekinumab in the U.S. OtulfiTM is contraindicated in patients with significant hypersensitivity to ustekinumab or to any of the excipients.

OtulfiTM (ustekinumab-aauz) is Fresenius Kabi’s fourth biosimilar granted a marketing authorization in the U.S., following previous approvals of its commercially available biosimilars Idacio® *** (adalimumab-aacf), Tyenne® **** (tocilizumab-aazg) and Stimufend® ***** (pegfilgrastim-fpgk). Fresenius Kabi’s growing pipeline of autoimmune and oncology biosimilars has several molecules in early and late-stage development.
