Elecoglipron, also referenced as AZD5004 or ECC5004, is the once-daily oral small-molecule GLP-1 receptor agonist that AstraZeneca licensed from Shanghai-based Eccogene in 2023 and is developing as the backbone of an oral cardiometabolic combination strategy. The drug is not a peptide, but acts on the same receptor as semaglutide and competes directly in the oral GLP-1 race alongside Lilly's orforglipron and Structure's aleniglipron.
The Phase 2b program met its endpoints in 2026. VISTA (obesity or overweight with comorbidity) and SOLSTICE (type 2 diabetes) both supported a Phase 3 transition, with SOLSTICE showing HbA1c reduction by 26 weeks. A Sunday June 7 ADA 2026 poster added Chinese Phase 1b safety, tolerability, and PK/PD data; the VISTA and SOLSTICE symposium followed Monday June 8. AstraZeneca plans to develop elecoglipron as an oral combination backbone, including pairings with dapagliflozin for diabetes, chronic kidney disease, and heart failure, and with AZD0780 for dyslipidemia.

BioSpace's reaction to AstraZeneca's elecoglipron VISTA Phase 2b readout (10.5% weight loss at 26 weeks) framed it as 'relatively underwhelming' next to Structure Therapeutics' aleniglipron (up to 16.3% at 44 weeks, Nature Medicine publication on Friday). Both are oral small-molecule GLP-1s with Phase 3 plans for the second half of 2026, but elecoglipron's lower number gives Structure a clearer differentiation story heading into its Phase 3 start. AstraZeneca will lean on its combination strategy with dapagliflozin and AZD0780 to position elecoglipron.
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.
Monday's data sharpened the oral GLP-1 competitive map. Lilly's Foundayo (orforglipron) leads with a Phase 3 head-to-head win over oral semaglutide and a Q2 FDA filing pending. Structure's aleniglipron sits closest, with 16.3% Phase 2b weight loss and Nature Medicine publication on Friday. AstraZeneca's elecoglipron just cleared Phase 2b. Chinese entrants Hengrui-Kailera (ribupatide, HRS-7535) added Phase 2 and 3 readouts. Novo's Wegovy pill remains the only currently-approved oral, but the next-wave field is now broad and head-to-head data are arriving fast.
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.
Eccogene and AstraZeneca will present multiple datasets for the oral small-molecule GLP-1 receptor agonist elecoglipron (AZD5004/ECC5004) at ADA 2026 on June 7-8, including a late-breaking Phase 1b study conducted in China, plus the Phase 2b VISTA trial in obesity (which met its primary endpoints) and the SOLSTICE Phase 2b trial in type 2 diabetes. The slate deepens the oral-GLP-1 contest forming below Lilly's orforglipron.
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.
