The timing is ripe for a robust biosimilar market in China, given the rapid increase of novel biologics approved to treat cancer and inflammatory diseases in the country over the past decade and the looming patent cliffs for several established biologics. As of December, the NMPA had approved more than 20 biosimilars that were developed in China. Most of those referenced just two biologics – Roche AG’s cancer drug Avastin (bevacizumab) and Abbvie Inc.’s immunology drug Humira (adalimumab). In 2022, the oncology and immunology biosimilar market in China garnered sales of about $2 billion, according to Clarivate estimates. To reach their full potential in China though, biosimilars must win over prescribers and patients.
Follow-on biologic makers in China have been working to capitalize on looming patent cliffs of blockbuster biologics. Advancing biosimilars of denosumab (Prolia/Xgeva; Amgen Inc.) and semaglutide are the latest examples.

Biosimilar competition to Amgen Inc.’s denosumab (Prolia/Xgeva) is rising globally, with Mabwell (Shanghai) Bioscience Co. Ltd. gaining the latest China NMPA approval of Maiweijian (TK-006) on April 8. Mabwell’s wholly owned subsidiary, Jiangsu T-mab Biopharma Co. Ltd., gained NMPA clearance of Maiweijian (120 mg) as the first denosumab biosimilar for the indications of U.S.-licensed Xgeva for bone-related diseases.
