No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone4

In this study, Cagrilintide 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 Cagrilintide.

  1. 01AnimalNot a test of Cagrilintide aloneAnimal study (in vivo)Efficacy outcome

    In animals, co-administration of GLP-1R and CTR/AMYR agonists into the LDTg suppressed food intake more than either treatment alone.

    In plain wordsIn animals, giving both drugs into one brain area reduced eating more than giving either drug alone.

    Summary
    We also showed that co-administration of GLP-1R and CTR/AMYR agonists into the LDTg resulted in a greater suppression of food intake and reduction in body weight compared to either treatment alone.
    2 context sentences
    Summary · context
    CagriSema is a fixed-ratio combination of the long-acting GLP-1R agonist semaglutide and the calcitonin (CTR)/amylin receptor (AMYR) agonist cagrilintide that shows greater efficacy for weight loss compared to GLP-1R and CTR/AMYR mono-agonists alone.
    Summary · context
    In this study, we investigate the laterodorsal tegmental nucleus (LDTg) as a central site of integration for GLP-1R and CTR/AMYR signaling, and explore the effect of co-agonism in this nucleus on feeding behavior.

    In an operant model, combined GLP-1R and CTR/AMYR agonist treatment in the LDTg significantly reduced motivation to self-administer a highly palatable food reward.

    In plain wordsIn animals, the combined treatment in one brain area reduced the drive to work for tasty food.
