NCT03720548

Brief Summary

The main purpose of this study is to evaluate the safety and tolerability of LY3372993 in healthy participants and participants with AD. The study will also investigate how much LY3372993 gets into the bloodstream and test the effects of LY3372993 in participants with AD. The study has two parts:

  • Part A - Healthy participants will receive LY3372993 or placebo. Part A will last up to 17 weeks;
  • Part B - Participants with AD will receive LY3372993 or placebo. Part B will last about 317 days.

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 up to Day 562

Secondary Outcomes (5)

  • Pharmacokinetics (PK): Area Under the Concentration Versus Time Curve of LY3372993 After a Single Dose

    Predose up to Day 85

  • PK: Maximum Observed Concentration (Cmax) of LY3372993 After a Single Dose

    Predose up to Day 85

  • PK: AUC of LY3372993 at Steady State after Multiple Doses

    Week 14 through Week 18

  • PK: Cmax of LY3372993 at Steady State After Multiple Doses

    Week 14 through Week 18

  • Pharmacodynamics (PD): Change from Baseline in Amyloid Load

    Baseline, Week 28
