A Phase 1 interventional study of Eloralintide and Tirzepatide and Eloralintide in Overweight and Obesity, sponsored by Eli Lilly and Company. Completed at 3 sites in United States. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-01-30.
Sponsored by Eli Lilly and Company · Phase 1, Interventional, and Basic science
The purpose of this study is to evaluate how well eloralintide and eloralintide with tirzepatide is tolerated and what side effects may occur in participants with overweight or obesity. The study drug will be administered subcutaneously (SC) (under the skin). Blood tests will be performed to check how much eloralintide and eloralintide with tirzepatide get into the bloodstream and how long it takes the body to eliminate it.
There will be 6 cohorts. The study will last up to approximately 26 weeks, excluding screening for Cohorts A and B, 11 weeks for Cohorts C and D, and 12 weeks for Cohorts E and F.
3,670 studies on the registry are indexed under Overweight; 849 are open to participants now.
This study's enrollment of 188 is above the median of 73 across 3,175 interventional studies indexed under Overweight.
