NCT04586907 | Completed Phase 1

• 2 other identifiers: 17730J2R-MC-YAAB
• Study Type: interventional
• Target: 85
• Locations: 1 country
• Sites: 1

Brief Summary

The main purpose of this study is to learn more about the safety of LY3537021 and any side effects that might be associated with it in healthy participants and participants with type 2 diabetes mellitus (T2DM). Blood tests will be performed to check how much LY3537021 gets into the bloodstream and how long the body takes to eliminate it. This study will last up to about 19 weeks including screening period.

Conditions

Healthy; Type 2 Diabetes Mellitus

Outcome Measures

Primary Outcomes (1)

• Number of Participants with One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration

  A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module

  Baseline through Day 119 (Part A) and Day 57 (Part B)

Secondary Outcomes (2)

• Pharmacokinetics (PK): Area Under the Concentration Versus Time Curve (AUC) of LY3537021

  Predose Day 1 through Day 119 (Part A) and Day 57 (Part B)

• PK: Maximum Concentration (Cmax) of LY3537021

  Predose Day 1 through Day 119 (Part A) and Day 57 (Part B)
