Individuals taking tirzepatide misplaced as much as 52 lb. (24 kg) on this 72-week part 3 research
63% of members taking tirzepatide 15 mg achieved at the very least 20% physique weight reductions as a key secondary endpoint
INDIANAPOLIS, April 28, 2022 /PRNewswire/ — Tirzepatide (5 mg, 10 mg, 15 mg) achieved superior weight reduction in comparison with placebo at 72 weeks of therapy in topline outcomes from Eli Lilly and Firm’s (NYSE: LLY) SURMOUNT-1 medical trial, with members shedding as much as 22.5% (52 lb. or 24 kg) of their physique weight for the efficacy estimandi. This research enrolled 2,539 members and was the primary part 3 international registration trial evaluating the efficacy and security of tirzepatide in adults with weight problems, or obese with at the very least one comorbidity, who would not have diabetes. Tirzepatide met each co-primary endpoints of superior imply p.c change in physique weight from baseline and better proportion of members attaining physique weight reductions of at the very least 5% in comparison with placebo for each estimandsii. The research additionally achieved all key secondary endpoints at 72 weeks.
For the efficacy estimand, members taking tirzepatide achieved common weight reductions of 16.0% (35 lb. or 16 kg on 5 mg), 21.4% (49 lb. or 22 kg on 10 mg) and 22.5% (52 lb. or 24 kg on 15 mg), in comparison with placebo (2.4%, 5 lb. or 2 kg). Moreover, 89% (5 mg) and 96% (10 mg and 15 mg) of individuals taking tirzepatide achieved at the very least 5% physique weight reductions in comparison with 28% of these taking placebo.
In a key secondary endpoint, 55% (10 mg) and 63% (15 mg) of individuals taking tirzepatide achieved at the very least 20% physique weight reductions in comparison with 1.3% of these taking placebo. In an extra secondary endpoint not managed for sort 1 error, 32% of members taking tirzepatide 5 mg achieved at the very least 20% physique weight reductions. The imply baseline physique weight of members was 231 lb. (105 kg).
“Weight problems is a persistent illness that always doesn’t obtain the identical commonplace of care as different situations, regardless of its affect on bodily, psychological and metabolic well being, which may embrace elevated danger of hypertension, coronary heart illness, most cancers and decreased survival,” stated Louis J. Aronne, MD, FACP, DABOM, director of the Complete Weight Management Heart and the Sanford I. Weill Professor of Metabolic Analysis at Weill Cornell Drugs, weight problems knowledgeable at NewYork-Presbyterian/Weill Cornell Medical Heart and Investigator of SURMOUNT-1. “Tirzepatide delivered spectacular physique weight reductions in SURMOUNT-1, which may characterize an necessary step ahead for serving to the affected person and doctor partnership deal with this advanced illness.”
For the treatment-regimen estimandiii, outcomes confirmed:
- Common physique weight reductions: 15.0% (5 mg), 19.5% (10 mg), 20.9% (15 mg), 3.1% (placebo)
- Share of members attaining physique weight reductions of ≥5%: 85% (5 mg), 89% (10 mg), 91% (15 mg), 35% (placebo)
- Share of members attaining physique weight reductions of ≥20%: 30% (5 mg, not managed for sort 1 error), 50% (10 mg), 57% (15 mg), 3.1% (placebo)
The general security and tolerability profile of tirzepatide was much like different incretin-based therapies authorized for the therapy of weight problems. Essentially the most generally reported antagonistic occasions had been gastrointestinal-related and customarily gentle to average in severity, often occurring through the dose escalation interval. For these handled with tirzepatide (5 mg, 10 mg and 15 mg, respectively), nausea (24.6%, 33.3%, 31.0%), diarrhea (18.7%, 21.2%, 23.0%), vomiting (8.3%, 10.7%, 12.2%) and constipation (16.8%, 17.1%, 11.7%) had been extra steadily skilled in comparison with placebo (9.5% [nausea], 7.3% [diarrhea], 1.7% [vomiting], 5.8% [constipation]).
Therapy discontinuation charges attributable to antagonistic occasions had been 4.3% (5 mg), 7.1% (10 mg), 6.2% (15 mg) and a pair of.6% (placebo). The general therapy discontinuation charges had been 14.3% (5 mg), 16.4% (10 mg), 15.1% (15 mg) and 26.4% (placebo).
Individuals who had pre-diabetes at research graduation will stay enrolled in SURMOUNT-1 for an extra 104 weeks of therapy following the preliminary 72-week completion date to judge the affect on physique weight and the potential variations in development to sort 2 diabetes at three years of therapy with tirzepatide in comparison with placebo.
“Tirzepatide is the primary investigational drugs to ship greater than 20 p.c weight reduction on common in a part 3 research, reinforcing our confidence in its potential to assist folks dwelling with weight problems,” stated Jeff Emmick, MD, Ph.D., vp, product growth, Lilly. “Weight problems is a persistent illness that requires efficient therapy choices, and Lilly is working relentlessly to assist folks with weight problems and modernize how this illness is approached. We’re proud to analysis and develop doubtlessly progressive therapies like tirzepatide, which helped almost two thirds of members on the best dose scale back their physique weight by at the very least 20 p.c in SURMOUNT-1.”
Tirzepatide is a novel investigational once-weekly GIP (glucose-dependent insulinotropic polypeptide) receptor and GLP-1 (glucagon-like peptide-1) receptor agonist, representing a brand new class of medicines being studied for the therapy of weight problems. Tirzepatide is a single peptide that prompts the physique’s receptors for GIP and GLP-1, two pure incretin hormones. Weight problems is a persistent, progressive illness attributable to disruptions within the mechanisms that management physique weight, typically resulting in a rise in meals consumption and/or a lower in vitality expenditure. These disruptions are multifactorial and may be associated to genetic, developmental, behavioral, environmental and social components. To study extra, go to Lilly.com/weight problems.
Lilly will proceed to judge the SURMOUNT-1 outcomes, which can be introduced at an upcoming medical assembly and submitted to a peer-reviewed journal. Further research are ongoing for tirzepatide as a possible therapy for weight problems or obese.
About tirzepatide
Tirzepatide is a once-weekly GIP (glucose-dependent insulinotropic polypeptide) receptor and GLP-1 (glucagon-like peptide-1) receptor agonist that integrates the actions of each incretins right into a single novel molecule. GIP is a hormone that will complement the consequences of GLP-1 receptor agonists. In preclinical fashions, GIP has been proven to lower meals consumption and improve vitality expenditure due to this fact leading to weight reductions, and when mixed with GLP-1 receptor agonism, might lead to better results on markers of metabolic dysregulation reminiscent of physique weight, glucose and lipids. Tirzepatide is in part 3 growth for adults with weight problems or obese with weight-related comorbidity and is at present below regulatory assessment as a therapy for adults with sort 2 diabetes. It’s also being studied as a possible therapy for non-alcoholic steatohepatitis (NASH) and coronary heart failure with preserved ejection fraction (HFpEF). Research of tirzepatide in obstructive sleep apnea (OSA) and in morbidity/mortality in weight problems are deliberate as nicely.
About SURMOUNT-1 and the SURMOUNT medical trial program
SURMOUNT-1 (NCT04184622) is a multi-center, randomized, double-blind, parallel, placebo-controlled trial evaluating the efficacy and security of tirzepatide 5 mg, 10 mg and 15 mg to placebo as an adjunct to a reduced-calorie food plan and elevated bodily exercise in adults with out sort 2 diabetes who’ve weight problems, or obese with at the very least one of many following comorbidities: hypertension, dyslipidemia, obstructive sleep apnea or heart problems. The trial randomized 2,539 members throughout the U.S., Argentina, Brazil, China, India, Japan, Mexico, Russia and Taiwan in a 1:1:1:1 ratio to obtain both tirzepatide 5 mg, 10 mg or 15 mg or placebo. The co-primary aims of the research had been to reveal that tirzepatide 10 mg and/or 15 mg is superior in proportion of physique weight reductions from baseline and proportion of members attaining ≥5% physique weight discount at 72 weeks in comparison with placebo. Individuals who had pre-diabetes at research graduation will stay enrolled in SURMOUNT-1 for an extra 104 weeks of therapy following the preliminary 72-week completion date to judge the affect on physique weight and potential variations in development to sort 2 diabetes at three years of therapy with tirzepatide in comparison with placebo.
All members within the tirzepatide therapy arms began the research at a dose of tirzepatide 2.5 mg once-weekly after which elevated the dose in a step-wise strategy at four-week intervals to their last randomized upkeep dose of 5 mg (through a 2.5 mg step), 10 mg (through steps at 2.5 mg, 5 mg and seven.5 mg) or 15 mg (through steps at 2.5 mg, 5 mg, 7.5 mg, 10 mg and 12.5 mg).
The SURMOUNT part 3 international medical growth program for tirzepatide started in late 2019 and has enrolled greater than 5,000 folks with weight problems or obese throughout six medical trials, 4 of that are international research. Outcomes from SURMOUNT-2, -3, and -4 are anticipated in 2023.
