Celltrion Presents Phase 3 Results for Denosumab Biosimilar

Apr 15, 2024

The Korea Times reports that Celltrion presented the 78-week results of its Phase 3 study of CT-P41, biosimilar to Amgen’s Prolia® (denosumab), at the World Congress on Osteoporosis held in London from 11-14 April 2024.  It is reported that the clinical trial showed CT-P41 has equivalent efficacy, pharmacokinetics and safety to Prolia® in postmenopausal women with osteoporosis.

Celltrion applied to the FDA for marketing authorisation of CT-P41 in December 2023.  The first Prolia® (denosumab) biosimilar approved in the US was Sandoz’s Jubbonti®, on 5 March 2024.

Prolia® (denosumab) biosimilars have been approved in Canada (Sandoz’s Jubbonti® on 20 February 2024) and China (Boan Biotech’s Boyoubei® in November 2022 and Mabwell’s Mailishu® in March 2023).  Other companies have Prolia® biosimilars under development including Samsung Bioepis, Alvotech, Intas, and Shanghai Henlius Biotech.
