Prolia, developed by Amgen, is a monoclonal antibody injection that targets Receptor Activator of Nuclear factor Kappa-B Ligand (RANKL) proteins in osteoporosis patients. According to Amgen's annual report, the drug's sales reached 3.2 trillion won ($2.6 billion) in 2019.
With the launch of the trial, the company aims to begin a global phase 3 clinical trial by the first half of next year and prepare for commercialization by February 2025, which is when Prolia's U.S. substance patent expires.
Celltrion expects that CT-P41 will become the firm's future growth drive as well as CT-P17, a Humira biosimilar currently undergoing review by the European Medicines Agency, CT-P16 (Avastin biosimilar), CT-P39 (Xolair biosimilar), and CT-P43 (Stelara biosimilar).
"The company is developing osteoporosis treatments to further expand its product portfolio along with existing autoimmune and anticancer treatments such as Remsima, Truxima, and Herzuma," a company official said. "We plan to stably supply high-quality biosimilar products at reasonable prices by introducing products to big global markets such as the U.S. and Europe."
