Boehringer-Zealand drug leads to 16.6% weight loss in late-stage trial #-boehringer-zealand-drug-leads-to-16-6-weight-loss-in-late-stage-trial Reuters 2:00 AM ET Apr-28-2026

FRANKFURT, April 28 (Reuters) - Boehringer Ingelheim announced on Tuesday that its experimental obesity treatment produced an average weight reduction of up to 16.6% in a late-stage trial, as the privately held German pharmaceutical company aims to close the gap with obesity drug leaders Eli Lilly (LLY.NaE) and Novo Nordisk.

According to a company statement, the Phase III trial found that patients receiving survodutide shed 16.6% of their body weight after 76 weeks, versus 3.2% among those given a placebo.

The study enrolled adults who were obese or overweight and did not have type 2 diabetes.

Boehringer obtained the rights in 2011 to exclusively develop and commercialise survodutide from Denmark's Zealand Pharma, which is eligible for royalty payments on worldwide sales.

Complete findings from the Phase III trial, known as SYNCHRONIZE-1, will be shared at the American Diabetes Association's 2026 Scientific Sessions, taking place from June 5 to June 8, 2026.

Survodutide imitates the appetite-suppressing gut hormone GLP-1, which is the target of injectable drugs like Novo's Wegovy, while also mimicking the gut hormone glucagon—a dual approach some developers believe could enhance weight loss. Altimmune (ALT.NaE) is working on a drug that leverages the effects of these same two hormones. In early 2024, survodutide showed encouraging mid-stage results for treating fatty liver, also referred to as metabolic-dysfunction-associated steatohepatitis, or MASH. (Reporting by Patricia Weiss.

A friend of mine took part in the Survo Study, I believe it was Phase II. She had Type 2 Diabetes and dropped 60 pounds, plus her blood sugar returned to normal. It was her doctor who got her into the study. A year later, she has kept the weight off. Once the study ended, they simply stopped everything for her. I need to check in with her again about how things are going.

That is really impressive! With semaglutide and tirzepatide, you do not always see this. My guess is that glucagon agonism is what wipes out visceral fat. I suspect reta might be able to produce that same kind of maintenance effect. After you bring back liver function by cutting NAFLD down a lot, the picture shifts.

Because of that, I am currently taking survodutide (together with tirzepatide), and I have to admit the extra weight loss has been quite small, yet my waist circumference keeps going down, even if it is slow. For now, I will keep going with it.

One pity: the report never says what dosage was given. I would really like to find that out.

Maybe the specifics will come out in June, at the American Diabetes Association's 2026 Scientific Sessions on June 5th
