Brief summary

The main purpose of this study is to assess how fast donanemab (LY3002813) gets into the blood stream and how long it takes the body to remove it when administered as single dose in healthy participants. The study will also evaluate the safety and tolerability of donanemab. The study will last up to approximately 22 weeks.

Outcome results

Primary

Pharmacokinetics (PK): Area Under the Concentration Versus Time Curve From Time Zero to Four Weeks (AUC[0-4 Weeks]) of Donanemab (i.e) Period 2, Period 4, Period 6.

As per the prespecified analysis, AUC\[0-4 weeks\] will be calculated as the sum of AUC0-2weeks for: * treatment period 1 and 2 (dosing days 1, 15 respectively) represented as period 2 * treatment period 3 and 4 (dosing days 29, 43 respectively) represented as period 4 * treatment period 5 and 6 (dosing days 57, 71 respectively) represented as period 6.

Time frame: Predose, end of infusion, 24, 48, 72, 96, 168, 336 hours post-dose on days 1, 15, 29, 43, 57, 71

Population: All enrolled participants who received at least one IV infusion of donanemab and had evaluable PK data.
