News Release

In ACHIEVE-4, Foundayo met the primary objective of non-inferiority vs. insulin glargine with a 16% lower risk of MACE-4 events and a 23% lower risk of MACE-3 events

In a pre-planned analysis, the risk of all-cause death was 57% lower for Foundayo vs. insulin glargine, showing the potential for more comprehensive health benefits

With these data, Lilly plans to submit Foundayo for the treatment of type 2 diabetes to the U.S. Food and Drug Administration by the end of Q2

INDIANAPOLIS, April 16, 2026 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) today announced positive topline results from the Phase 3 ACHIEVE-4 trial evaluating the efficacy and safety of Foundayo (orforglipron), compared to insulin glargine in adults with type 2 diabetes and obesity or overweight at increased cardiovascular risk. ACHIEVE-4, the largest and longest study of Foundayo in type 2 diabetes to date, enrolled more than 2,700 participants across 15 countries. In the trial, Foundayo met the primary endpoint by demonstrating a non-inferior risk of major adverse cardiovascular events (MACE-4), including cardiovascular death, heart attack, stroke or hospitalization for unstable and sudden chest pain, compared to insulin glargine. In addition, Foundayo showed superior improvements in A1C and body weight at 52 weeks vs. insulin glargine, which persisted through 104 weeks of therapy. While not controlled for multiplicity, the risk of all-cause death was significantly lower for Foundayo vs. insulin glargine.

"Across seven Phase 3 studies enrolling more than 11,000 patients, Foundayo has demonstrated a consistent safety and efficacy profile," said Thomas Seck, M.D., senior vice president of product development, Lilly Cardiometabolic Health. "ACHIEVE-4 adds a new dimension to that evidence — cardiovascular safety and a lower observed risk of all-cause death in patients who carry elevated cardiovascular risk. Together with the simplicity of a once-daily pill that requires no food or water restrictions, we believe Foundayo could be an important new treatment option for people with type 2 diabetes."

In the trial, the risk of cardiovascular death, heart attack, stroke, or hospitalization for unstable sudden chest pain was 16% lower for Foundayo vs. insulin glargine (hazard ratio: 0.84; 95.0% CI: 0.59 to 1.20), meeting the prespecified criteria for demonstrating non-inferiority (upper limit of 95.0% CI of the hazard ratio < 1.8).¹ The risk of all-cause death was 57% lower with Foundayo vs. insulin glargine (hazard ratio: 0.43; 95.0% CI: 0.25 to 0.75; nominal p = 0.002).² Foundayo also showed clinically meaningful improvements from baseline across several cardiovascular risk factors, including non-HDL cholesterol, systolic blood pressure, triglycerides, and hsCRP.²

ACHIEVE-4 Topline Results:

The overall safety and tolerability profile of Foundayo in ACHIEVE-4 was generally consistent with previous trials and with the GLP-1 class. The most common adverse events for patients taking Foundayo were nausea, vomiting, diarrhea, decreased appetite, and constipation. During the 52-week minimum treatment period, 10.6% of patients taking Foundayo discontinued treatment due to adverse events. ACHIEVE-4 included a thorough analysis of potential drug-induced liver injury (DILI), and these analyses confirmed there was no hepatic safety signal, consistent with all prior studies in the ACHIEVE and ATTAIN programs.

Lilly will submit Foundayo for the treatment of type 2 diabetes to the U.S. FDA by the end of the second quarter under the Commissioner's National Priority Review Voucher.

About Foundayo (orforglipron) 
Foundayo (orforglipron) is FDA-approved for adults with obesity, or some adults with overweight who also have weight-related medical problems to reduce excess body weight and maintain weight reduction long term, alongside a reduced-calorie diet and increased physical activity. Foundayo is a once-daily small molecule (non-peptide) oral glucagon-like peptide-1 receptor agonist that can be taken any time of the day without restrictions on food and water intake.⁴ Orforglipron was discovered by Chugai Pharmaceutical Co., Ltd. and licensed by Lilly in 2018. In addition to chronic weight management, Foundayo is being studied as a potential treatment for type 2 diabetes, obstructive sleep apnea, osteoarthritis knee pain, hypertension, peripheral artery disease and stress urinary incontinence.

About ACHIEVE-4 and ACHIEVE clinical trial program 
ACHIEVE-4 (NCT05803421) is a Phase 3, event-driven, randomized, open-label trial evaluating the efficacy and safety of Foundayo compared with insulin glargine in adults with type 2 diabetes and obesity or overweight (BMI ≥25 kg/m²) with increased risk of cardiovascular events. The trial randomized 2,749 participants across the U.S., Argentina, Austria, Brazil, Czechia, Germany, Greece, India, Italy, Mexico, Puerto Rico, Romania, Slovakia, South Korea, Spain and Turkey to receive either escalating doses of Foundayo or insulin glargine. The primary objective of the study was to demonstrate that Foundayo was non-inferior in the risk of major adverse cardiovascular events (MACE-4) compared to insulin glargine in adults with type 2 diabetes and obesity or overweight with increased risk for cardiovascular events who have taken at least one and no more than three oral anti-diabetic medications for at least 90 days prior to study start. Study participants had an A1C between ≥7.0% and ≤10.5% (≥7.5% and ≤10.5% if background diabetes medication includes a sulfonylurea) and a BMI of ≥25 kg/m² with stable weight (±5%) for at least 90 days prior to study start. Participants randomized to Foundayo initiated treatment with 1 mg capsule (corresponds to 0.8 mg tablets) once daily and increased the dose every four weeks until reaching a maximum tolerated dose (up to 36 mg capsule/17.2 mg tablet).

The ACHIEVE Phase 3 global clinical development program for Foundayo began in 2023 and enrolled more than 6,000 people with type 2 diabetes across five global registrational trials.
