AMB-702 demonstrates superior target coverage and efficacy in lean non-human primates 

The dataset was shared as part of a poster presentation at the American Diabetes Association’s (ADA) 86th Scientific Sessions

BOULDER, Colo., June 5, 2026 /PRNewswire/ — Ambrosia Biosciences Inc. (“Ambrosia”), today announced preclinical data supporting its small molecule GLP-1 receptor agonist development candidate, AMB-702, in a poster presentation at the American Diabetes Association’s (ADA) 86th Scientific Sessions.

AMB-702 demonstrated sustained weight loss and reduction in food intake over 7 days of daily dosing in a lean non-human primate (NHP) model. In a head-to-head comparison, AMB-702 achieved placebo-adjusted mean weight loss of 12.6% after 7 days of daily dosing at 2 mg/kg, compared to 5.4% for orforglipron at the same dose and formulation. AMB-702 also demonstrated improved glycemic control and enhanced insulin secretion in an intraperitoneal glucose tolerance test (IPGTT) in a humanized GLP-1 receptor mouse model.

Additional data showing improved performance in a clinic-ready formulation and additional comparator studies will also be presented.

“These data are consistent with AMB-702’s improved in vitro and PK profile, including superior target coverage over 24 hours, improved cell potency, flatter peak-to-trough and reduced plasma protein binding. The superiority of AMB-702 in lean NHP models underscores its differentiation and the potential of next-generation molecules for obesity and metabolic diseases,” said Patrice Lee, Ph.D., President, R&D.

“Importantly, AMB-702 has the potential for lower effective human dosing, which we believe could substantially improve scalability. We look forward to advancing AMB-702 into the clinic early next year,” said Nick Traggis, CEO. “Beyond AMB-702, Ambrosia’s next-generation, small molecule pipeline also includes a once-weekly GLP-1 receptor agonist, a GIP receptor antagonist, and an amylin receptor agonist, all enabling a significant opportunity for combination therapies.”
