A Study of LY2969822 in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate how safe LY2969822 (study drug) is and whether it causes any side effects. The study will also measure how much of the study drug gets into the blood stream and how long it takes the body to get rid of the study drug. This is the first time that this study drug is being given to participants. This study is for research purposes only and is not intended to treat any medical condition.

Detailed Description
-----------------
Participants in Part A will complete three study periods, which together will last about 40 days. Participants in Parts B and C will complete one study period which will last about 17 days, but the total study time is about 40 days. Each participant may only enroll in one part. Screening is required within 28 days prior to the start of the study for all participants.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With One or More Serious Adverse Events (SAEs) Considered by the Investigator to be Related to Study Drug Administration | A summary of other nonserious adverse events (AEs) and all SAEs, regardless of causality, is located in the Reported Adverse Events section. | Baseline Through End of Study (up to Week 7) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetics (PK): Maximum Plasma Concentration (Plasma Cmax) of Prodrug LY2969822 and Active Metabolite LSN2934747 | Pharmacokinetics (PK): Maximum Plasma Concentration (Plasma Cmax) of Prodrug LY2969822 and Active Metabolite LSN2934747 | All Cohorts: Day 1 - 0 Hours (H), 0.5 H, 1 H, 2 H, 3 H, 4 H, 6 H, 9 H, 12 H, 16 H; Cohort 3: Day 10 - 0 H, 0.5 H, 1 H, 2 H, 3 H, 4 H, 6 H, 9 H, 12 H, 16 H; Cohorts 3 - 8: Day 14 - 0 H, 0.5 H,1 H, 2 H, 3 H, 4 H, 6 H, 9 H, 12 H, 16 H | 
| PK: Maximum Cerebrospinal Fluid Concentrations (CSF Cmax) of Prodrug LY2969822 and Active Metabolite LSN2934747 | PK: Maximum Cerebrospinal Fluid Concentrations (CSF Cmax) of Prodrug LY2969822 and Active Metabolite LSN2934747 | Cohort 8: Day 14 - 0 H, 0.5 H,1 H, 2 H, 3 H, 4 H, 6 H, 9 H, 12 H, 16 H |
