AstraZeneca presented VISTA Phase 2b data at ADA 2026 with simultaneous Lancet publication. In adults with obesity or overweight plus comorbidity, oral elecoglipron 75 mg produced 10.5% mean weight loss at 26 weeks versus 0.6% on placebo, continuing to 11.8% by 36 weeks, alongside blood-pressure and inflammation reductions. The companion SOLSTICE T2D trial showed 1.9-point HbA1c reductions with 90% reaching HbA1c under 7% and 7.7% weight loss. AstraZeneca announced an extensive Phase 3 program covering obesity, T2D, and cardiovascular and kidney outcome trials.
Eccogene and AstraZeneca presented a Sunday June 7 poster on the safety, tolerability, and PK/PD of elecoglipron (AZD5004/ECC5004) in Chinese adults with obesity or overweight, with or without type 2 diabetes. The Monday June 8 symposium covers the VISTA Phase 2b obesity readout and the SOLSTICE Phase 2b trial in type 2 diabetes, where the oral GLP-1 reduced HbA1c at 26 weeks and supported a Phase 3 transition. AstraZeneca plans to develop elecoglipron as an oral combination backbone alongside dapagliflozin in diabetes/CKD/HF and AZD0780 in dyslipidemia.
AstraZeneca's eleglipron (formerly elecoglipron / AZD5004 / ECC5004), the oral small-molecule GLP-1 agonist licensed from Eccogene in 2023, met primary endpoints in two Phase 2b trials with results detailed at the company's April 29 Q1 print: VISTA (NCT06579092, 310 obesity patients, 26-week weight loss) and SOLSTICE (NCT06579105, 406 type-2 diabetes patients, 26-week HbA1c change vs semaglutide and placebo). AstraZeneca held back exact weight-loss numbers, framing the molecule as 'very competitive,' with full data scheduled for the American Diabetes Association meeting in June. The company committed to a comprehensive Phase 3 program targeting both weight-loss efficacy and outcome benefits, with monotherapy and fixed-dose combination programs anchored against the SYH2082 dual-agonist and LiquidGel monthly-dosing platform from the $18.5B CSPC Pharmaceuticals collaboration.
