AIMS/HYPOTHESIS: The aim of this study was to assess the dose-response effects of the subcutaneous glucagon receptor/glucagon-like peptide-1 receptor dual agonist survodutide (BI 456906) on HbA_1c levels and bodyweight reduction. METHODS: This Phase II, multicentre, randomised, double-blind, parallel-group, placebo-controlled study, conducted in clinical research centres, assessed survodutide in participants aged 18-75 years with type 2 diabetes, an HbA_1c level of 53-86 mmol/mol (7.0-10.0%) and a BMI of 25-50 kg/m² on a background of metformin therapy. Participants were randomised via interactive response technology to receive survodutide (up to 0.3, 0.9, 1.8 or 2.7 mg once weekly [qw; dose group (DG) 1-4, respectively] or 1.2 or 1.8 mg twice weekly [DG 5 and 6, respectively]), placebo or semaglutide (up to 1.0 mg qw). Participants and all those involved in the trial conduct/analysis were blinded; the semaglutide arm was open-label. The primary endpoint was absolute change from baseline in HbA_1c after 16 weeks' treatment. The key secondary endpoint was relative change from baseline in bodyweight after 16 weeks' treatment. RESULTS: A total of 413 participants were randomised (DG1, n=50; DG2, n=50; DG3, n=52; DG4, n=50; DG5, n=51; DG6, n=50; semaglutide, n=50; placebo, n=60). The full analysis set comprised 411 treated participants (DG6, n=49; placebo, n=59). Adjusted mean (95% CI) HbA_1c decreased from baseline (mean ± SD 64.7±9.2 mmol/mol [8.07±0.84%] after 16 weeks' treatment: DG1 (n=41), -9.92 mmol/mol (-12.27, -7.56; -0.91% [-1.12, -0.69]); DG2 (n=46), -15.95 mmol/mol (-18.27, -13.63; -1.46% [-1.67, -1.25]); DG3 (n=36), -18.72 mmol/mol (-21.15, -16.29; -1.71% [-1.94, -1.49]); DG4 (n=33), -17.01 mmol/mol (-19.59, -14.43; -1.56% [-1.79, -1.32]); DG5 (n=44), -17.84 mmol/mol (-20.18, -15.51; -1.63% [-1.85, -1.42]); DG6 (n=36), -18.38 mmol/mol (-20.90, -15.87; -1.68% [-1.91, -1.45]). The mean reduction in HbA_1c was similar with low-dose survodutide (DG2: -15.95 mmol/mol [-1.46%]; n=46) and semaglutide (-16.07 mmol/mol [-1.47%]; n=45). Mean (95% CI) bodyweight decreased dose-dependently up to -8.7% (-10.1, -7.3; DG6, n=37); survodutide ≥1.8 mg qw produced greater bodyweight reductions than semaglutide (-5.3% [-6.6, -4.1]; n=45). Adverse events (AEs) were reported for 77.8% of survodutide-treated participants (mainly gastrointestinal), 52.5% receiving placebo and 52.0% receiving semaglutide. CONCLUSIONS/INTERPRETATION: Survodutide reduced HbA_1c levels and bodyweight after 16 weeks' treatment in participants with type 2 diabetes. Dose-related gastrointestinal AEs could be mitigated with slower dose escalations. TRIAL REGISTRATION: ClinicalTrials.gov NCT04153929 and EudraCT 2019-002390-60.
