Brief summary

The purpose of this study is to measure how much LY3314814 gets into the bloodstream when it is given as a single dose by mouth and as an intravenous (IV) infusion over two hours. The study will last at least two weeks for each participant, not including screening.

Absolute Bioavailability of LY3314814

Absolute bioavailability was quantified using a mixed-effects analysis of variance (ANOVA) model applied to the log-transformed dose-normalized AUC(0-∞) of LY3314814 oral dosing and IV administered \[13C415N3\]-LY3314814.

Time frame: Day 1: Predose:0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 8, 12, 24, 48, 72, 96 and 120 hours post-dose

Population: All participants who received at least one dose of study drug and have evaluable PK data.
