As competition rises in the Keytruda (pembrolizumab) biosimilar space, Celltrion Inc. is the latest to announce that it filed an IND application to the U.S. FDA to start a global phase III trial for its own Keytruda biosimilar, dubbed CT-P51. Incheon, South Korea-based Celltrion, which previously said it would differentiate from the pack by developing an easier-to-administer subcutaneous biosimilar of pembrolizumab, announced June 17 plans to start a global comparative phase III study of CT-P51 and Keytruda.
Celltrion Inc., of Incheon, South Korea, gained MFDS clearance of Eydenzelt (CT-P42) as a biosimilar referencing Regeneron Pharmaceuticals Inc./Bayer AG’s Eylea (aflibercept) on May 30. The news comes on the heels of the U.S. FDA approving the first Eylea interchangeable biosimilars on May 20.
South Korea’s Celltrion Inc. secured May 22 the European Commission’s go-ahead for Omlyclo (CT-P39) to be the first biosimilar to Genentech Inc./Novartis AG’s Xolair (omalizumab) in Europe for three of its major indications.
The U.S. FDA approved the country’s first two interchangeable biosimilars, or copy products, of Regeneron Pharmaceuticals Inc./Bayer AG’s Eylea (aflibercept) on May 20, to treat four eye-related conditions. The FDA granted the approvals to U.S.- and India-based Johnson & Johnson Services Inc./Biocon Biologics Ltd.’s Yesafili (aflibercept-jbvf; M-710) and South Korea’s Samsung Bioepis Co. Ltd.’s Opuviz (aflibercept-yszy; SB-15).
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.
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.
South Korean biosimilar-focused Alteogen Inc. said on March 27 that Chung Hye-shin, former chief strategy officer (CSO) and co-founder, sold 1.6 million of Alteogen shares for ₩316.4 billion (US$234.24 million) to foreign institutional investors.
