Innovent Biologics Inc.’s glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor dual agonist, mazdutide, met the primary endpoint of superiority in a head-to-head phase III trial in Chinese patients with type 2 diabetes compared to Eli Lilly and Co.’s GLP-1, dulaglutide, for glycemic control.

Homerun success of Novo Nordisk A/S’ semaglutide, which recently became the U.S.’s biggest blockbuster drug, is serving as an “inflection point” for obesity therapeutics and fueling the drive for new and improved therapies, speakers said at Bio Korea 2024 on May 8.

In the wake of Novo Nordisk’s semaglutide nabbing the title of the U.S.’s biggest blockbuster drug, it’s little surprise that Amgen Inc.’s obesity candidate, Maritide (maridebart cafraglutide), hogged the stage during the firm’s first-quarter earnings call after market close May 2, with company executives touting promising phase II data and a differentiated profile, sending shares of Thousand Oaks, Calif.-based Amgen (NASDAQ:AMGN) up nearly 12% to close May 3 at $311.29.

South Korea’s HK Inno.N Corp. said on May 2 that it gained exclusive development and commercial rights to Hangzhou, China-based Sciwind Biosciences Co. Ltd.’s once-weekly, injectable glucagon-like peptide-1 (GLP-1) agonist, XW-003 (ecnoglutide), in South Korea to treat type 2 diabetes and obesity.

Led by executives who helmed The Medicines Co., Metsera Inc. has launched with $290 million in financing to develop drugs for treating weight loss, obesity-related conditions and metabolic diseases. The company is stepping into high profile and lucrative glucagon-like peptide-1 territory forged by Eli Lilly and Co.’s Zepbound (tirzepatide) for chronic weight management and Novo Nordisk A/S’s Wegovy (semaglutide), also approved for long-term weight management.

Eli Lilly and Co. is planning to file for U.S. FDA approval later this year after reporting that tirzepatide met all primary and key secondary endpoints in two phase III trials in obstructive sleep apnea (OSA). Assuming approval, tirzepatide could become the first drug approved specifically for OSA, while providing potential entry access for Medicare Part D coverage, which is denied for the GLP-1 class of drugs approved as obesity medications.

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.

When it comes to whether Medicare Part D should cover the new anti-obesity drugs, the U.S. Centers for Medicare & Medicaid Services and lawmakers may be caught between the math and public pressure.
