At the American Society of Clinical Oncology (ASCO) conference, held from 31 May to 4 June 2024, Fresenius Kabi presented results of a Phase 3 study comparing its FKS518 with Amgen’s Prolia® (denosumab) in postmenopausal women with osteoporosis.  FKS518 was shown to have therapeutic equivalence to Prolia®, with similar safety profiles.  

On 27 May 2024, Fresenius Kabi announced that its BLA for denosumab was accepted for review by the US FDA as biosimilar to Prolia®.   

May 28, 2024

On 28 May 2024, Amgen filed a complaint against Celltrion in the United States District Court for the District of New Jersey alleging infringement of 29 patents relating to denosumab.  The allegations relate to Celltrion’s abbreviated Biologics Licence Application (aBLA) submitted in December 2023 for CT-P41, its biosimilar to Amgen’s Xgeva® and Prolia® (denosumab). 

In May 2023, Amgen sued Sandoz in the US over its denosumab biosimilars (Jubbonti® and Wyost®) asserting infringement of 21 denosumab patents.  That dispute was resolved in April 2024, enabling Sandoz to launch Jubbonti® and Wyost® from 31 May 2025 (or earlier in certain undisclosed circumstances).   

Jubbonti® and Wyost® were approved by the FDA on 5 March 2024 for all indications of, and as interchangeable with, Prolia® and Xgeva®, respectively.  No other denosumab biosimilars have received US approval to date. 

May 27, 2024

On 27 May 2024, Fresenius Kabi announced that its BLA for denosumab has been accepted for review by the US FDA as biosimilar to Amgen’s Prolia®.  The biosimilar is to be indicated for osteoporosis in men and women, including glucocorticoid-induced osteoporosis, and bone loss due to prostate or breast cancer. 

Sandoz’s Wyost® and Jubbonti® were the first denosumab biosimilars approved in the US in March 2024.  Following the April 2024 resolution of US BPCI litigation, commenced by Amgen against Sandoz in May 2023, Jubbonti® and Wyost® are expected to launch in the US from 31 May 2025. 

On 28 May 2024, Amgen commenced BPCIA litigation against Celltrion in the United States District Court for the District of New Jersey, alleging infringement of 29 patents relating to denosumab.  Celltrion applied to the FDA for marketing authorisation of its denosumab biosimilar, CT-P41, in December 2023.
