ClinicalTrials2 Apr 2026·Phase 3● 7/10i A Phase 3, Randomised, Double-blind, Parallel-group, 76-week, Efficacy and Safety Study of BI 456906 Administered Subcutaneously Compared With Placebo in Participants With Overweight or Obesity and Type 2 Diabetes Mellitus
Boehringer Ingelheim
Boehringer Ingelheim's survodutide (BI 456906) is being tested in a placebo-controlled phase 3 trial for weight loss in adults with overweight or obesity and type 2 diabetes. The 76-week study enrolled 755 participants randomized 2:1 active to placebo, measuring percentage weight loss and achievement of ≥5% weight reduction. This positions Boehringer as a potential third major player in the GLP-1 obesity market, currently dominated by Novo Nordisk's Wegovy and Eli Lilly's Zepbound. The trial completion in December 2025 could establish survodutide as another weekly injectable option for people with diabetes and obesity.
Strategic signal
Boehringer's survodutide represents the first major challenge to the Novo-Lilly duopoly in GLP-1 obesity therapy, with results due in late 2025. This timing creates a window before oral formulations mature, potentially allowing Boehringer to capture market share while Novo and Lilly focus on next-generation assets. The diabetes-obesity combination population mirrors successful positioning by both incumbents, suggesting payers may welcome a third option to drive competitive pricing. If survodutide matches incumbent efficacy, Boehringer could leverage its established diabetes relationships to accelerate uptake.
Original Abstract
This study is open to adults who are at least 18 years old and have a body mass index of 27 kg/m² or more. People can take part if they have type 2 diabetes and if they are currently being treated only with diet and exercise or with specific diabetes medications. Only people who have previously not managed to lose weight by changing their diet can participate.
The purpose of this study is to find out whether a medicine called survodutide (BI 456906) helps people living with overweight or obesity who also have diabetes to lose weight.
Participants are divided into 3 groups by chance, like drawing names from a hat. 2 groups get different doses of survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Every participant has a 2 in 3 chance of getting survodutide. Participants inject survodutide or placebo under their skin once a week for about one and a half years. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly.
Participants are in the study for about 1 year and 7 months. During this time, it is planned that participants visit the study site up to 14 times and receive 6 phone calls by the site staff.
The doctors check participants' health and take note of any unwanted effects. The study staff also regularly measure participants' body weight. The results are compared between the groups to see whether the treatment works. | Condition(s): Obesity; Diabetes Mellitus, Type 2 | Primary endpoint(s): Percentage change in body weight from baseline to Week 76; Achievement of body weight reduction ≥5% (yes/no) from baseline to Week 76 | Enrollment: 755 (actual) | Phase: Phase 3 | Sponsor: Boehringer Ingelheim | Expected completion: 2025-12-12 | Status: Active Not Recruiting | Last update: 2026-04-02
