The trial enrolled 755 adults who received weekly survodutide at 3.6 mg or 6.0 mg, or placebo. Up to 79.3% of participants on survodutide lost at least 5% of their body weight, versus 32.7% on placebo. HbA1c fell by up to 1.21 percentage points from a baseline of 7.4%, and up to 29.5% of treated participants reverted to normal blood sugar levels. Figures are based on the efficacy estimand.

Discontinuation due to gastrointestinal side effects was 18% on survodutide versus 1.2% on placebo, mostly during dose escalation. The full results were presented at EASD 2026 in Milan and published in The New England Journal of Medicine. Results from the cardiovascular outcomes trial SYNCHRONIZE-CVOT are expected later this year.

“We are very encouraged by the SYNCHRONIZE-2 results reported today by Boehringer Ingelheim, demonstrating the potential of survodutide in people living with obesity and type 2 diabetes, by providing both meaningful weight loss and glycemic control,” says David Kendall, Chief Medical Officer, Zealand Pharma.
