Breaking New Ground with Incretin Therapy in Diabetes

This editorial highlights the potential of dual incretin therapy (combining glucose dependent insulinotropic polypeptide [GIP] and GLP 1 receptor agonism) to advance diabetes treatment. Tirzepatide, a novel dual GIP/GLP 1 agonist, demonstrated superior glycemic control and weight loss compared to semaglutide in a recent trial, with mean glycated hemoglobin reductions of 2.30 percentage points (vs. 1.86) and weight loss of 13.1% at 40 weeks. The therapy also improved blood pressure and lipid profiles while maintaining a low hypoglycemia risk. With obesity driving diabetes and its complications, tirzepatide’s weight loss effects may offer additional benefits. Ongoing cardiovascular outcomes trials (e.g., SURPASS CVOT) will assess its potential for reducing cardiovascular and kidney disease risks. The editorial underscores the need for diverse clinical trial populations to ensure broad applicability of these advances.
