A Study of Insulin Efsitora Alfa (LY3209590) as a Weekly Basal Insulin Compared to Insulin Glargine in Adult Participants With Type 2 Diabetes on Multiple Daily Injections

Summary

The reason for this study is to evaluate if the once-weekly study drug insulin efsitora alfa (LY3209590) is safe and effective compared with daily insulin glargine in participants with Type 2 diabetes (T2D) that have already been treated with basal insulin and at least 2 injections per day of prandial insulin. The study consists of a 3-week screening/lead-in period, a 26-week treatment period and a 5-week safety follow-up period. The study will last up to 34 weeks.
