Summary

This study tested a new weekly medicine called retatrutide in 537 adults with type 2 diabetes whose blood sugar was not well controlled by diet and exercise alone. Participants received either the medicine or a placebo for about 11 months. The goal was to see if retatrutide safely lowers blood sugar and helps with weight loss.
