There was a time not that long ago when Merck & Co. Inc.’s Keytruda (pembrolizumab), with its multiple cancer indications, was seen as the heir apparent to Humira’s title of the biggest blockbuster drug. Not anymore. That title now belongs to Novo Nordisk A/S’ semaglutide, approved as Ozempic in 2017 to treat diabetes and as Wegovy in 2021 to help with weight loss.

Samsung Bioepis Co. Ltd. and Celltrion Inc. are making headway in Europe and U.S. with respective follow-on biologic products, with Samsung Bioepis the latest to gain EMA approval for Pyzchiva, a Stelara (ustekinumab, Janssen Pharmaceuticals Inc.) biosimilar, on April 23.

Having addressed the manufacturing issues that resulted in a few complete response letters, Alvotech Holdings SA and Teva Pharmaceutical Industries Ltd.’s biosimilars partnership is now on a roll, with the U.S. FDA approving the team’s second biosimilar, Selarsdi, less than two months after approving the first one, Simlandi, as an adalimumab interchangeable.

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.

Samsung Bioepis Co. Ltd., of Incheon, South Korea, is the latest to announce a win in the biosimilar space, gaining MFDS approval of Epyztek (SB-17) as the country’s first biosimilar to Stelara (ustekinumab, Janssen Pharmaceutical Inc.) on April 11.

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.
