Eli Lilly and Company: Lilly's triple agonist, retatrutide, delivered powerful weight loss in pivotal Phase 3 obesity trial

In TRIUMPH-1, participants on 12 mg retatrutide lost an average of 70.3 lbs (28.3%) over 80 weeks with 45.3% of participants achieving =30% weight loss, a level long associated with bariatric surgery

Individuals with a baseline BMI =35 who participated in a study extension continued to lose weight, and achieved up to an average of 85.0 lbs (30.3%) weight loss at 104 weeks

At the 4 mg dose, reached with only a single escalation step, participants lost an average of 47.2 lbs (19.0%) at 80 weeks with a lower observed discontinuation rate due to adverse events vs. placebo

INDIANAPOLIS, May 21, 2026 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY), the maker of Zepbound (tirzepatide) and Foundayo (orforglipron), today announced positive topline results from TRIUMPH-1, a Phase 3 clinical trial evaluating the efficacy and safety of retatrutide, an investigational, first-in-class GIP, GLP-1, and glucagon triple hormone receptor agonist, in adults with obesity or overweight and at least one weight-related comorbidity and without diabetes. At 80 weeks, all doses of retatrutide (4 mg, 9 mg, and 12 mg) met the primary and key secondary endpoints for obesity, delivering clinically meaningful weight loss.

"Obesity is a chronic disease, and people living with obesity deserve treatment options that match the complex biology of their neurometabolic disease," said Ania Jastreboff, M.D., Ph.D., Professor of Medicine & Pediatrics (Endocrinology) at the Yale School of Medicine, Director of the Yale Obesity Research Center (Y-Weight), and lead investigator. "It was impressive to see that every dose of retatrutide resulted in clinically meaningful weight reduction for nearly all participants, and people with severe obesity on the highest dose lost on average 30% of their body weight over two years. Importantly, treatment with retatrutide not only resulted in robust weight reduction, but also in clear improvements in assessed cardiometabolic health measures. For patients I see in clinic, retatrutide may potentially be a highly impactful future tool to treat their obesity and transform their health trajectory."

For the primary endpoint, participants taking retatrutide 9 mg and 12 mg lost an average of 64.4 lbs (25.9%) and 70.3 lbs (28.3%), respectively. Those taking the 4 mg dose of retatrutide, with just a single dose escalation step, lost an average of 47.2 lbs (19.0%). Notably, 65.3% of participants taking retatrutide 12 mg achieved a BMI <30, falling under the threshold for obesity at 80 weeks, including 37.5% of those who started with class 3 obesity (BMI =40).¹ In a pre-specified blinded extension for those with a BMI =35, participants who continued on retatrutide 12 mg to 104 weeks lost an average of 85.0 lbs (30.3%).² Additionally, retatrutide showed significant improvements from baseline across certain cardiovascular risk factors, including waist circumference, non-HDL cholesterol, triglycerides, systolic blood pressure and high-sensitivity C-reactive protein (hsCRP).

TRIUMPH-1 Efficacy Estimand Results³

Primary Endpoint at 80 Weeks
	Retatrutide 4 mg	Retatrutide 9 mg	Retatrutide 12 mg	Placebo
Percent change in body weight at 80 weeks from avg. baseline of 112.7 kg (248.5 lbs; BMI of 40.0 kg/m2)i	-19.0% (-21.4 kg; -47.2 lbs)	-25.9% (-29.2 kg; -64.4 lbs)	-28.3% (-31.9 kg; -70.3 lbs)	-2.2% (-2.5 kg; -5.5 lbs)
Key Secondary Endpoints at 80 Weeks
Change in waist circumference from baseline of 118.3 cm (46.6 in)	-16.3 cm (-6.4 in)	-21.8 cm (-8.6 in)	-24.1 cm (-9.5 in)	-3.6 cm (-1.4 in)
Percent of participants achieving body weight reduction of =25%	27.8 %	52.9 %	62.5 %	2.2 %
Percent of participants achieving body weight reduction of =30%	15.3 %	37.9 %	45.3 %	0.5 %
Percent of participants achieving body weight reduction of =35%	5.9 %	20.8 %	27.2 %	0.3 %
Pre-specified Extension at 104 Weeksii
	Retatrutide 4 mg to MTDiii	Retatrutide 9 mg to MTDiii	Retatrutide 12 mg to MTDiii	Placebo to Retatrutide MTDiii
Percent change in body weight at 104 weeks from avg. baseline of 121.7 kg (268.3 lbs; BMI of 42.8 kg/m2)	-27.9% (-33.2 kg; -73.3 lbs)	-29.5% (-36.6 kg; -80.7 lbs)	-30.3% (-38.5 kg; -85.0 lbs)	-19.2% (-22.6 kg; -49.9 lbs)

ⁱPercent body weight reduction with retatrutide 4 mg was a key secondary endpoint.
ⁱⁱThe extension period enrolled 532 participants with BMI =35 at baseline who had completed the main 80-week study and tolerated their assigned dose of medication.
ⁱⁱⁱParticipants in the trial extension received retatrutide at a maximum tolerated dose of 9 mg or 12 mg.

"TRIUMPH-1 highlights the importance of options and the potential for retatrutide to help people across various stages of their obesity journey," said Kenneth Custer, Ph.D., executive vice president and president, Lilly Cardiometabolic Health. "From the 4 mg dose, reaching nearly 20% weight loss with one escalation step, to the 12 mg dose that delivered a level of weight loss long associated with bariatric surgery, retatrutide offers the potential for a patient-centric approach to obesity.⁴ Together with Zepbound and Foundayo, retatrutide could build on Lilly's commitment to match treatments to the needs and preferences of patients."

For the treatment-regimen estimand, each dose level of retatrutide led to improvements across the primary and key secondary endpoints, as well as the pre-specified extension, including:⁵

• Percent change in body weight at 80 weeks: -17.6% (-19.8 kg; -43.7 lbs; 4 mg); -23.7% (-26.7 kg; -58.9 lbs; 9 mg); -25.0% (-28.2 kg; -62.1 lbs; 12 mg) and -3.9% (-4.4 kg; -9.7 lbs; placebo)
• Percent change in body weight at 104 weeks: -25.7% (-30.6 kg; -67.5 lbs; 4 mg to MTD); -28.7% (-35.6 kg; -78.4 lbs; 9 mg to MTD); -29.9% (-38.1 kg; -83.9 lbs; 12 mg to MTD) and -18.9% (-22.3 kg; -49.1 lbs; placebo to MTD)

The types of adverse events seen were generally consistent with trials of other incretin-based therapies. The most common adverse events among participants treated with retatrutide (4 mg, 9 mg, 12 mg, vs. placebo, respectively) were nausea (28.6%, 38.4% and 42.4% vs. 14.8%), diarrhea (25.2%, 34.1% and 32.0% vs. 13.5%), constipation (23.8%, 25.9% and 26.1% vs. 10.9%), vomiting (10.6%, 22.8% and 25.3% vs. 4.8%), and upper respiratory tract infection (14.2%, 12.2% and 13.1% vs. 11.6%). Incidences of dysesthesia occurred in 5.1%, 12.3%, and 12.5% of patients treated with retatrutide 4 mg, 9 mg, and 12 mg, respectively, compared with 0.9% with placebo, and incidences of urinary tract infections occurred in 7.5%, 8.8%, and 8.4% of patients treated with retatrutide 4 mg, 9 mg, and 12 mg, respectively, compared with 5.3% with placebo. Events of dysesthesia and urinary tract infections were generally mild to moderate, the majority resolved during treatment, and most participants continued taking retatrutide. Discontinuation rates due to adverse events were 4.1%, 6.9%, 11.3%, with retatrutide 4 mg, 9 mg, and 12 mg, respectively, compared with 4.9% with placebo.

Additional TRIUMPH-1 results will be presented at the 86^th annual American Diabetes Association Scientific Sessions, along with other results from Lilly's cardiometabolic pipeline. Additional detailed results will be presented at future medical meetings and published in peer-reviewed journals. More results from the TRIUMPH Phase 3 clinical trial program will be shared later this year, including data from TRIUMPH-2, which is evaluating retatrutide in adults with obesity or overweight and type 2 diabetes, and TRIUMPH-3, which is evaluating retatrutide in adults with obesity or overweight and established cardiovascular disease.

About retatrutide
Retatrutide is an investigational, once-weekly, triple hormone receptor agonist, which activates the body's receptors for glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon. Lilly is studying retatrutide in several Phase 3 clinical trials to evaluate its potential efficacy and safety in obesity and overweight with at least one weight-related medical problem, type 2 diabetes, knee osteoarthritis pain, moderate-to-severe OSA, chronic low back pain, cardiovascular and renal outcomes, and metabolic dysfunction-associated steatotic liver disease. Retatrutide is an investigational molecule that is legally available only to participants in Lilly's clinical trials.

About TRIUMPH-1 and the TRIUMPH clinical trial program
TRIUMPH-1 (NCT05929066) is a Phase 3, 80-week, randomized, double-blind, placebo-controlled master trial comparing the efficacy and safety of retatrutide with placebo in adults with obesity or overweight. TRIUMPH-1 included a master trial for obesity and two basket trials for knee osteoarthritis pain or moderate-to-severe obstructive sleep apnea. The study randomized 2,339 participants in a 1:1:1:1 ratio to receive either retatrutide 4 mg, 9 mg, 12 mg, or placebo. Participants randomized to retatrutide initiated treatment with 2 mg once weekly and increased the dose in a step-wise approach every four weeks until reaching the target dose of 4 mg (via one step at 2 mg), 9 mg (via steps at 2 mg, 4 mg and 6 mg) or 12 mg (via steps at 2 mg, 4 mg, 6 mg and 9 mg). TRIUMPH-1 included a pre-specified extension period of 104 weeks. The extension period enrolled 532 participants with BMI =35 at week 0 who completed the main 80-week study and tolerated their assigned dose of medication. Participants received retatrutide once weekly for an additional 24 weeks, including a blinded escalation to maximum tolerated dose (9 mg or 12 mg). Data described in this press release refer to the master trial and extension period; analyses of the two basket trials for knee osteoarthritis pain and moderate-to-severe obstructive sleep apnea will be released subsequently.

The initial TRIUMPH Phase 3 clinical development program is evaluating the safety and efficacy of retatrutide for the treatment of patients with obesity or overweight, moderate-to-severe OSA and obesity, and knee osteoarthritis pain across four global registrational trials. The program, which began in 2023, has enrolled more than 5,800 participants with additional results anticipated over the next year.
