New Zepbound-Like GLP-1 Drug Leads to 16% More Weight Loss

• A brand new weight reduction drug known as survodutide has proven promising ends in a part 3 medical trial.
• The drug, which stimulates GLP-1 and glucagon receptors, led to a 16.6% drop in physique weight.
• Survodutide additionally diminished waist circumference, an indicator of metabolic well being.
• Consultants hope the drug will likely be helpful for each weight problems and liver illness; nonetheless, it’s not but accepted to be used.

Boehringer Ingelheim, a biopharmaceutical firm headquartered in Ingelheim, Germany, has announced promising outcomes from its Section 3 SYNCHRONIZE-1 medical trial testing survodutide.

Survodutide is a novel dual-action drug designed to deal with weight problems and associated metabolic situations.

The trial, performed throughout a number of worldwide websites and involving 725 adults residing with weight problems or chubby however with out kind 2 diabetes, concluded in April 2026 after 76 weeks of therapy.

Survodutide, which prompts each glucagon-like peptide-1 (GLP-1) and glucagon receptors, demonstrated important and sustained weight reduction.

Individuals misplaced a mean of 16.6% of their physique weight, a big enchancment in comparison with simply 3.2% within the placebo group.

Therapy with survodutide additionally confirmed significant metabolic enhancements, together with reductions in waist circumference, a key predictor of cardiometabolic risk.

Survodutide (BI 456906) is just like the energetic ingredient tirzepatide (Mounjaro, Zepbound) in that it combines two mechanisms of motion. Nonetheless, it acts on a unique mixture of hormone receptors.

Whereas GLP-1 receptor agonists can aid weight loss by reducing appetite and rising fullness and satiety, survodutide goes a step additional by activating glucagon receptors, that are believed to assist regulate metabolic capabilities within the liver.

That is important as a result of it could permit an extra discount in liver fats, probably serving to to cut back liver irritation and fibrosis, two causes of obesity-related problems.

The SYNCHRONIZE-1 trial evaluated survodutide’s security and efficacy in adults with overweight or obesity, excluding these with kind 2 diabetes.

Individuals obtained weekly injections of survodutide at doses of three.6 milligrams or 6.0 milligrams, or a placebo, over almost a yr and a half.

The first objectives of the examine had been to evaluate the proportion change in physique weight and the proportion of members attaining no less than a 5% discount in physique weight from baseline after 76 weeks of therapy.

In accordance with the researchers, as much as 85.1% of these handled with survodutide achieved no less than a 5% discount of their weight, contrasting with solely 38.8% within the placebo group who reached this purpose.

On common, individuals misplaced 16.6% of their weight, which was equal to about 39.2 kilos. The researchers additional famous that this was primarily composed of fats quite than lean muscle tissue.

One other optimistic indicator was a big lower in waist circumference among the many members. Waist circumference is related to visceral abdominal fat, which is linked to metabolic dysfunction and cardiovascular risk.

The researchers additional reported that widespread GLP-1 gastrointestinal side effects, corresponding to nausea and vomiting, had been largely delicate to average and non permanent. These occasions occurred primarily in the course of the early part of therapy when the dose was being titrated up. No new security issues emerged in the course of the trial.

Hector Perez, MD, lead bariatric surgeon at Renew Bariatrics and an advisor at Bariatric Stories, instructed Healthline that in the case of weight reduction, it’s too early to name survodutide a “game-changer.”

“[W]hile the reported weight reduction quantity is spectacular, we have already got very sturdy performers on this class,” he stated.

Perez, who was not concerned within the SYNCHRONIZE-1 trial, cautioned that the total knowledge needs to be made accessible earlier than any claims are made about its unwanted effects.

“In actual life, the perfect drug is usually the one sufferers can truly keep on,” he stated.

Nonetheless, survodutide acts on a number of metabolic pathways, so it might be helpful past its appetite-suppressing results, Perez famous.

Survodutide could deal with liver illness by addressing the underlying metabolic issues that trigger fatty liver, corresponding to excess body fat, insulin resistance, and irritation.

Its potential to cut back urge for food can decrease the quantity of fats saved within the liver, Perez defined.

However, its glucagon-based motion may assist the physique burn extra fats, together with dangerous visceral and liver fats.

This might result in improved liver enzymes, much less liver irritation, and slower development of scarring.

“In easy phrases, it could assist the liver heal by enhancing the entire metabolic system,” stated Perez. “If this drug actually improves liver irritation and fibrosis markers whereas driving weight reduction, that’s the place it may carve out an actual area of interest.”

Kristin Kuminski, a registered dietitian nutritionist with The RX Index, who wasn’t concerned within the trial, known as the outcomes “important,” putting survodutide at an analogous stage of efficacy to tirzepatide.

Nonetheless, she stated that any questions you ask your doctor ought to deal with the way it compares to present weight reduction medication so far as unwanted effects, and the way it performs for individuals with co-existing situations like fatty liver illness.

“It’s not but accepted, so the dialog with a health care provider proper now’s about what’s within the pipeline, whether or not present GLP-1 options are working, and whether or not to observe for survodutide trials to take part in,” she stated.

Perez added that you just must also focus on different sensible questions along with your physician earlier than taking a weight reduction remedy, corresponding to whether or not you’re a good candidate for bariatric surgical procedure.

“[M]any individuals lose years attempting medicines when surgical procedure would have given them a greater long-term consequence,” he stated.

You must also ask whether or not weight reduction is reasonable on your physique, how one can shield muscle whereas dropping pounds, what unwanted effects you’ll be able to anticipate, what occurs while you cease taking the remedy, and whether or not your insurance coverage covers your therapy.

“Principally, my recommendation is to decide on your therapy in accordance with your physique, your habits, your funds, and what you’ll be able to realistically maintain for years as an alternative of getting impressed with a shiny new drug,” Perez stated.
