Type 2 & other diabetes

Efficacy and safety of once-weekly cagrilintide–semaglutide (cagrilintide-semaglutide (CagriSema)) in adults with type 2 diabetes inadequately controlled on diet and exercise (REIMAGINE 1): a randomised, double-blind, placebo-controlled, phase 3a study

Lancet Diabetes EndocrinolPublished Randomised controlled trial

Authors' conclusion

In a population of people with early-stage type 2 diabetes inadequately controlled with diet and exercise, cagrilintide-semaglutide (2.4 mg each and 1.0 mg each) was superior to placebo in reducing HbA1c. The safety profile was consistent with the GLP-1 receptor agonist class and previous safety data for cagrilintide.
