A Phase 1, Open-Label, Single and Multiple Dose Study to Investigate the Safety, Tolerability, and Relative Bioavailability of Single and Multiple Weekly Subcutaneous Doses of Eloralintide, and Single and Multiple Weekly Subcutaneous Doses of Eloralintide With Tirzepatide in Participants With Overweight or Obesity
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.
• Have safety laboratory test results within normal reference range for the population or investigative site, or results with acceptable deviations that are judged to be not clinically significant by the investigator. Participants with a history of thyroid disease or on thyroid medication will need to be biochemically euthyroid as assessed by measuring thyroid stimulating hormone at screening
• Have a body mass index (BMI) within the range of 27.0 to 40.0 kilogram per square meter (kg/m²), inclusive
• Have had a stable weight for the 3 months prior to screening, that is, less than 5% body weight change
