Lilly's SURMOUNT-2 results published in The Lancet show tirzepatide achieved a mean weight reduction of 15.7% at the highest dose (15 mg) in adults with obesity or overweight and type 2 diabetes

Detailed results presented at the American Diabetes Association's^® 83^rd Scientific Sessions 

Lilly has completed tirzepatide's submission for chronic weight management to the FDA

INDIANAPOLIS, June 24, 2023 /PRNewswire/ -- Detailed results from SURMOUNT-2, a phase 3 clinical trial evaluating the efficacy and safety of Eli Lilly and Company's (NYSE: LLY) tirzepatide (10 mg and 15 mg) for chronic weight management in participants with obesity or overweightⁱ and type 2 diabetes, showed that tirzepatide led to superior weight reduction versus placebo for both doses. The data were presented during a symposium at the American Diabetes Association's^® (ADA) 83^rd Scientific Sessions and were simultaneously published in The Lancet.

Tirzepatide met both co-primary endpoints and all key secondary endpoints compared to placebo for both estimands, with those taking tirzepatide achieving a mean weight reduction of 13.4% (29.8 lb. or 13.5 kg) on 10 mg and 15.7% (34.4 lb. or 15.6 kg) on 15 mg compared to 3.3% (7.0 lb. or 3.2 kg) on placebo for the efficacy estimand, which evaluates the treatment effect if all participants adhered to treatment. For the efficacy estimand, 81.6% (10 mg) and 86.4% (15 mg) of people taking tirzepatide achieved at least 5% body weight reduction, compared to 30.5% of those taking placebo.

Both doses of tirzepatide achieved all key secondary endpoints at 72 weeks of treatment for the efficacy estimand, including:

• Percentage of participants taking the 15 mg tirzepatide dose achieving ≥15% and ≥20% body weight reductions: 51.8% (≥15% reduction) and 34.0% (≥20% reduction), compared to 2.6% and 1.0% with placebo
• Percentage of participants achieving A1C of <5.7%: 55.3% (10 mg) and 50.2% (15 mg), compared to 2.8% with placebo
• Reduction in waist circumference: 11.2 cm (10 mg) and 13.8 cm (15 mg), compared to 3.4 cm with placebo
• Reduction in fasting glucose: 49.2 mg/dL (10 mg) and 51.7 mg/dL (15 mg), compared to 2.4 mg/dL with placebo

Pooled tirzepatide doses (10 mg and 15 mg) resulted in significantly greater improvements compared to placebo in systolic blood pressure (-7.2 mmHg vs. -1.0 mmHg), fasting triglycerides (-28.6% vs. -5.8%), HDL-cholesterol (8.2% vs. 1.1%) and non-HDL-cholesterol (-6.6% vs. 2.3%).

"People living with type 2 diabetes in many cases have been exposed to excess weight for years and often face increased difficulties in achieving weight loss results, typically losing 30% less weight than those who have obesity without type 2 diabetes. They need options to help overcome those challenges and achieve meaningful weight reductions," said W. Timothy Garvey, MD, MACE, MABOM, Professor of Medicine at the University of Alabama at Birmingham (UAB), Director of the UAB Diabetes Research Center and Principal Investigator of SURMOUNT-2. "Tirzepatide not only helped people achieve body weight reductions of up to 15.7%, but also helped to significantly lower A1C without severe hypoglycemia and led to improvements in other cardiometabolic endpoints."

Additionally, tirzepatide met the co-primary and all key secondary endpoints for the treatment-regimen estimand, which represents the average results of all study participants regardless of treatment adherence, including:

• Mean body weight reductions: 12.8% (10 mg), 14.7% (15 mg), 3.2% (placebo)
• Percentage of participants achieving body weight reductions of ≥5%: 79.2% (10 mg), 82.8% (15 mg), 32.5% (placebo)
• Percentage of participants achieving at least ≥20% body weight reduction: 21.5% (10 mg) and 30.8% (15 mg), compared to 1.0% with placebo
• Percentage of participants achieving A1C of <5.7%: 46.0% (10 mg) and 48.6% (15 mg), compared to 3.9% with placebo

The overall safety profile of tirzepatide was consistent with previously reported SURMOUNT and SURPASS trials and similar to incretin-based therapies approved for the treatment of obesity and overweight. The most commonly reported adverse events were gastrointestinal-related and were generally mild to moderate in severity, and usually occurred during the dose-escalation period. For those treated with tirzepatide (10 mg and 15 mg, respectively), nausea (20.2%, 21.9%), diarrhea (19.9%, 21.5%), vomiting (10.9%, 13.2%) and constipation (8.0%, 9.0%) were more frequently reported compared to placebo (6.3% [nausea], 8.9% [diarrhea], 3.2% [vomiting], 4.1% [constipation]).

"At Lilly, bringing new treatments to people with obesity is a priority and we are proud to share more evidence that solidifies our belief in tirzepatide as a treatment that will impact the way patients manage this disease," said Mike Mason, Executive Vice President and President, Lilly Diabetes and Obesity. "With these results in hand, we have completed our submission for chronic weight management to the U.S. FDA. We look forward to the future of obesity care and the opportunity to bring potential new treatments, like tirzepatide, to people with obesity and overweight."

Regulatory action for the U.S. submission for tirzepatide in adults with obesity, or overweight with weight-related comorbidities is expected by the end of 2023. 

About SURMOUNT-2 and the SURMOUNT clinical trial program^1,2

SURMOUNT-2 (NCT04657003) was a multi-center, randomized, double-blind, parallel, placebo-controlled trial comparing the efficacy and safety of tirzepatide 10 mg and 15 mg to placebo as an adjunct to a reduced-calorie diet and increased physical activity in adults with obesity or overweight and type 2 diabetes. The trial randomized 938 participants across the U.S., Argentina, Brazil, India, Japan, Puerto Rico, Russia and Taiwan in a 1:1:1 ratio to receive tirzepatide 10 mg, 15 mg or placebo. The co-primary objectives of the study were to demonstrate that tirzepatide 10 mg and/or 15 mg is superior in mean percentage change in body weight from baseline and percentage of participants achieving ≥5% body weight reduction at 72 weeks compared to placebo.

All participants in the tirzepatide treatment arms started the study at a dose of tirzepatide 2.5 mg once-weekly and then increased the dose in a stepwise approach at four-week intervals to their final randomized maintenance dose of 10 mg (via steps at 2.5 mg, 5 mg and 7.5 mg) or 15 mg (via steps at 2.5 mg, 5 mg, 7.5 mg, 10 mg and 12.5 mg).

The race and ethnicity of the U.S. participants in SURMOUNT-2 were mostly representative of the U.S. population. About 18% of U.S. participants were African American or Black and about 41% of U.S. participants were Hispanic. Lilly continues to prioritize efforts to increase enrollment of racially and ethnically diverse patients in our clinical trials.

The SURMOUNT phase 3 global clinical development program for tirzepatide in chronic weight management began in late 2019 and has enrolled more than 5,000 people with obesity or overweight across six registration studies, four of which are global studies. The primary period of SURMOUNT-1 was completed in 2022 and results from SURMOUNT-3 and -4 are anticipated this year.

About tirzepatide

Tirzepatide is a once-weekly GIP (glucose-dependent insulinotropic polypeptide) receptor and GLP-1 (glucagon-like peptide-1) receptor agonist. Tirzepatide is a single molecule that activates the body's receptors for GIP and GLP-1, which are natural incretin hormones. Both GIP and GLP-1 receptors are found in areas of the human brain important for appetite regulation. Tirzepatide has been shown to decrease food intake and modulate fat utilization. Tirzepatide is in phase 3 development for adults with obesity, or overweight with weight-related comorbidity. It is also being studied as a potential treatment for people with obesity and/or overweight with heart failure with preserved ejection fraction (HFpEF), obstructive sleep apnea (OSA), and non-alcoholic steatohepatitis (NASH). Studies of tirzepatide in chronic kidney disease (CKD) and in morbidity/mortality in obesity (MMO) are also ongoing.

Tirzepatide was approved as Mounjaro^® (tirzepatide) by the FDA on May 13, 2022. Mounjaro is a glucose-dependent insulinotropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor agonist indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.
