  1. 01HumanRandomized controlled trialSafety outcome

    In adults with type 2 diabetes, gastrointestinal adverse events were more frequent in the semaglutide arms (73% and 80%) than in the arms without semaglutide (60% and 69%).

    Summary
    Gastrointestinal adverse events were more frequent with semaglutide (nine [60%] with placebo plus placebo, 11 [69%] with placebo plus GIP, 11 [73%] with semaglutide plus placebo, and 12 [80%] with semaglutide plus GIP).

    This single-centre, double-blind, parallel-group, randomised, placebo-controlled trial was conducted at the Center for Clinical Metabolic Research (Hellerup, Denmark).
    Summary · context
    Participants were randomly assigned (1:1:1:1), using a block randomisation list, to receive either placebo plus placebo, placebo plus GIP, semaglutide plus placebo, or semaglutide plus GIP (all self-administered subcutaneously).

Studies that did not test the peptide alone3

In this study, Semaglutide was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Semaglutide.

    In adults with type 2 diabetes on semaglutide, GIP infusion added to semaglutide did not change 14-day mean sensor glucose versus semaglutide plus placebo.

    In plain wordsIn adults with type 2 diabetes on semaglutide, adding a GIP infusion did not improve blood sugar compared with semaglutide plus placebo.
