On 1 December 2025, Sandoz announced the EU launch of Jubbonti® and Wyost®, biosimilars to Amgen’s Prolia® and Xgeva® (denosumab), respectively. Jubbonti® and Wyost® were approved for all reference indications by the European Commission (EC) in May 2024, and are the first and only denosumab biosimilars to be launched in the EU.
The EU launch comes 6 months after the US launch of Jubbonti® and Wyost® in June 2025, which followed a settlement agreement entered into by Sandoz and Amgen in April 2024 resolving US patent infringement litigation commenced by Amgen in May 2023 and permitting US launch of Jubbonti® and Wyost® from 31 May 2025.
