Kailera Therapeutics (NASDAQ: KLRA) is the U.S. biotech holding global ex-Greater-China rights to Hengrui Pharma's obesity peptide portfolio under the May 2024 up-to-$5+ billion collaboration agreement. The two lead assets: ribupatide (a once-weekly subcutaneous GIP/GLP-1/glucagon triple agonist peptide currently in China Phase 3 registrational trials, mean weight loss nearly 18% at 48 weeks) and HRS-7535 (KAI-7535 in the Kailera pipeline, an oral once-daily small-molecule GLP-1 receptor agonist that completed OUTSTAND-1 and OUTSTAND-2 Phase 3 trials in China).
On September 2, 2026, Hengrui disclosed that China's NMPA accepted marketing authorization applications for HRS-7535 in both obesity and type 2 diabetes based on the OUTSTAND Phase 3 program data. Chinese Phase 3 obesity data showed mean weight loss of up to 10.9% at Week 44 (11.1% at Week 50 with continued treatment) versus 2.5% for placebo. If approved, HRS-7535 would be the first oral small-molecule GLP-1 receptor agonist marketed in China.
Kailera is prepping the global ex-China Phase 3 program for both ribupatide and HRS-7535 (KAI-7535). Commercial positioning: ribupatide would be the second-in-class triple agonist option to Eli Lilly's retatrutide (28.3% weight loss in TRIUMPH-1), and HRS-7535 would compete with Lilly's Foundayo (orforglipron) and Novo Nordisk's Wegovy pill in the oral obesity segment. Kailera June 2026 IPO on NASDAQ raised $476 million at launch. Stories here cover clinical readouts, regulatory progression, and the broader Chinese-origin GLP-1 pipeline.

Kailera Therapeutics (NASDAQ: KLRA) continues through September 2026 the ramp toward global ex-China Phase 3 initiation for ribupatide (a once-weekly subcutaneous injection GIP/GLP-1/glucagon triple agonist peptide licensed globally ex-China from Hengrui Pharma under the May 2024 up-to-$5+ billion collaboration). The China Phase 3 program is complete with mean weight loss of nearly 18% at 48 weeks in Chinese overweight and obese adults. Ribupatide oral formulation (HRS-7535, licensed as KAI-7535 to Kailera ex-China) had NMPA marketing authorization applications accepted in China September 2, 2026 for both obesity and type 2 diabetes based on the OUTSTAND-1 and OUTSTAND-2 Phase 3 trials. The global ex-China ribupatide Phase 3 program is designed to run against Eli Lilly's retatrutide (28.3% weight loss in TRIUMPH-1) as the second-in-class triple-agonist option, and Kailera has signaled ambition to file in the U.S. within 12-18 months of Phase 3 readout. Ribupatide would be the third Chinese-origin GLP-1-class asset to reach U.S. clinical development, following Innovent-Lilly mazdutide and Sciwind-Pfizer ecnoglutide.
Hengrui Pharma (SHA: 600276, HKEX: 1276) disclosed Wednesday September 2, 2026 that China's National Medical Products Administration (NMPA) accepted the marketing authorization application for HRS-7535 (an oral once-daily small-molecule GLP-1 receptor agonist) for long-term weight management in adults with obesity or overweight, plus a separate marketing authorization application for HRS-7535 in type 2 diabetes based on the Phase 3 OUTSTAND-1 and OUTSTAND-2 trials. The Chinese Phase 3 obesity trial delivered mean weight loss of up to 10.9% at Week 44 (11.1% at Week 50 with continued treatment) versus 2.5% for placebo in the 180 mg group. If approved, HRS-7535 would become the first oral small-molecule GLP-1 receptor agonist marketed in China. HRS-7535 is licensed to Kailera Therapeutics (NASDAQ: KLRA) for global rights outside Greater China; the U.S. Phase 3 program is planned to initiate imminently. HRS-7535 would compete with Novo Nordisk's Wegovy pill (oral semaglutide) and Eli Lilly's Foundayo (orforglipron) in oral obesity therapeutics.
Kailera Therapeutics (NASDAQ: KLRA) received sweeping positive analyst coverage following its August 12, 2026 Q2 2026 earnings report. Kailera confirmed an active Investigational New Drug (IND) application with the FDA for ribupatide oral (KAI-9531-T) and global Phase 3 obesity trials planned for H1 2027. Analyst response: according to 6 analysts, the average rating for KLRA stock is Strong Buy, with a 12-month average price target of $42.60 representing 82.83% upside from the $17.95-$19.50 trading range on August 13-14. Named ratings include TD Cowen at Buy with a $57 price target, Evercore ISI at Outperform, and William Blair at Outperform. The company holds cash, cash equivalents, and marketable securities expected to support execution of multiple clinical milestones with runway into mid-2028. Ribupatide mechanism: a once-weekly GLP-1/GIP dual agonist peptide (mechanistically similar to Eli Lilly's tirzepatide) with the ribupatide injection Phase 2 trial reaching 23.6% mean weight loss at 8 mg over 36 weeks, and the oral formulation reaching up to 12.1% weight loss with 38.6% of participants achieving at least 15% loss at Week 26 in Hengrui's Phase 2 trial. The Phase 2b high-dose injection trial in obesity is fully enrolled with data anticipated in mid-2027.
Kailera Therapeutics (NASDAQ: KLRA) reported August 12, 2026 Q2 2026 financial results and disclosed an active Investigational New Drug (IND) application with the US FDA for ribupatide oral (KAI-9531-T), a triple agonist (GLP-1, GIP, and glucagon receptor) peptide for obesity being co-developed with Hengrui Pharma. Global Phase 3 obesity trials are planned to initiate in H1 2027. Phase 2 data foundation: Hengrui's Phase 2 trial in adults with obesity documented up to 12.1% mean weight loss with no observed plateau at Week 26 and up to 38.6% of participants achieving at least 15% weight loss at the 25 mg and 50 mg once-daily oral doses. A ribupatide injection Phase 2b high-dose trial in obesity is fully enrolled with data anticipated in mid-2027. Ribupatide competes mechanistically with Eli Lilly's retatrutide (once-weekly injectable triple agonist, roughly 28.7% weight loss at 68 weeks in Phase 3 TRIUMPH-4) in the triple-agonist class. The oral formulation could compete with Lilly's orforglipron (oral small-molecule GLP-1 agonist, roughly 7.5-11.2% weight loss over 72 weeks) and Novo Nordisk's Wegovy pill (oral semaglutide 25/50 mg). Kailera holds US and ex-China commercial rights via a license from Hengrui.
Kailera Therapeutics and Hengrui Pharma reported positive topline Phase 3 data from a Chinese T2D trial of HRS-7535, an oral small-molecule GLP-1 receptor agonist licensed to Kailera. Most adverse events were mild-to-moderate GI, with no Grade 3 hypoglycemic events and no liver-safety signal. Hengrui plans to submit a Chinese NDA for HRS-7535 in T2D and will share detailed efficacy data at an upcoming scientific conference. The readout extends the China-led oral-GLP-1 pipeline alongside ribupatide and aleniglipron.
