Mazdutide (IBI362) is a GLP-1/glucagon dual receptor agonist that Innovent Biologics licensed from Eli Lilly and develops for obesity and type 2 diabetes, with its lead market in China. The dual mechanism pairs GLP-1's appetite and glycemic effects with glucagon's energy-expenditure and hepatic-fat actions, placing it in the same class as survodutide and pemvidutide.
The Phase 3 GLORY program anchors the data. GLORY-1 supported Innovent's China obesity filing, and GLORY-2 reported 18.55% mean weight loss at its higher dose. At ADA 2026 in New Orleans (June 5-8), Innovent brings GLORY-2 alongside DREAMS-3, a head-to-head trial against semaglutide, plus next-generation metabolic-pipeline data. China's NMPA approved mazdutide for obesity in 2025, making it one of the first homegrown incretin therapies to reach that market.

At ADA 2026 on Sunday June 7, Innovent presented the Phase 3 GLORY-2 trial of mazdutide 9 mg in Chinese adults with obesity, presented by Leili Gao of Peking University People's Hospital. The dual GLP-1/glucagon agonist drove up to 20.1% mean weight loss and met its primary endpoint and all key secondary endpoints. The result extends China's homegrown obesity-peptide leadership, with mazdutide already approved by China's NMPA in 2025.
Innovent's DREAMS-3 Phase 3b head-to-head trial of mazdutide versus semaglutide in Chinese adults with type 2 diabetes and obesity was presented Sunday June 7 by Linong Ji of Peking University People's Hospital. On the composite primary endpoint, 48.0% of mazdutide-treated patients reached HbA1c under 7% plus at least 10% body weight reduction versus 21.0% on semaglutide. The readout is the first Phase 3 head-to-head defeat for semaglutide outside Lilly's tirzepatide series.
The American Diabetes Association's 86th Scientific Sessions open June 5-8 with the year's deepest metabolic-peptide slate. Lilly presents full TRIUMPH-1 obesity data and the first retatrutide diabetes Phase 3, TRANSCEND-T2D-1, plus the orforglipron ACHIEVE program comparing the oral GLP-1 against dapagliflozin, oral semaglutide, and placebo. Innovent's mazdutide brings GLORY-2 and the DREAMS-3 head-to-head versus semaglutide, AstraZeneca's eleglipron carries full Phase 2b data, and Lilly's GLP-1/GIP/glucagon/amylin/calcitonin quintuple agonist takes a plenary slot.
The American Diabetes Association 2026 Scientific Sessions opens in New Orleans on June 5 — three weeks out from today's Sunday digest. The peptide-relevant slate includes multiple Eli Lilly retatrutide TRIUMPH program presentations (some of the seven 2026 readouts expected to land at ADA), the Lilly + Indiana Biosciences Research Institute quintuple agonist (GLP-1/GIP/glucagon/amylin/calcitonin) animal-data poster on May 29, AstraZeneca's full Phase 2b VISTA and SOLSTICE data for eleglipron (formerly elecoglipron/AZD5004/ECC5004) after the April 29 topline, Innovent Biologics' mazdutide multi-program presentations (GLORY-2 18.55% weight loss, DREAMS-3 head-to-head vs semaglutide), Boehringer Ingelheim survodutide SYNCHRONIZE-1 full Phase 3 data, and Pfizer berobenatide (MET-097i) VESPER program updates. ADA combined with the May 21 ASCO abstract drop set up a heavy June peptide news cycle.
Innovent Biologics announced May 12 that it will present multiple clinical and preclinical results from mazdutide and its next-generation obesity & metabolic pipeline at the 2026 American Diabetes Association Scientific Sessions in New Orleans, June 5-8. Mazdutide is a GLP-1/glucagon dual agonist developed initially for the Chinese market. The Phase 3 GLORY-2 trial in Chinese adults with moderate-to-severe obesity reported a mean 18.55% weight reduction at 60 weeks on 9 mg dosing (vs ~3% placebo); 44% of GLORY-2 patients hit ≥20% body weight loss vs 2.5% on placebo. The Phase 3 head-to-head DREAMS-3 trial in T2D + obesity showed 48% of mazdutide patients hit HbA1c <7% + ≥10% weight loss vs 21% on semaglutide at week 32. The 9 mg dose is under NMPA review for approval in China. Mazdutide is the leading non-Lilly dual GLP-1/glucagon program competing with Boehringer's survodutide and earlier-stage Western programs.
