LY2216684 + Quinidine (CYP2C19 Poor Metabolizers)
Participants were predicted to have a cytochrome P450 (CYP)2C19 poor metabolizer (PM) phenotype, as determined by genotyping analysis. Period 1 (Days 1-7): a single, oral dose of 18 milligrams (mg) LY2216684 was administered on Day 1. Period 2 (Days 8-15): 300 mg quinidine sulfate controlled release was administered orally, once daily on Days 8-15. Additionally, a single, oral dose of 18 mg LY2216684 was administered on Day 11.
LY2216684 (CYP2C19 Extensive Metabolizers)
Participants were predicted to have a cytochrome P450 (CYP)2C19 extensive metabolizer (EM) phenotype, as determined by genotyping analysis. Period 1 (Days 1-7): a single, oral dose of 18 milligrams (mg) LY2216684 administered on Day 1. Period 2 (Days 8-15): EM participants did not participate in this period.

PRIMARY outcome

Timeframe: Predose up to 120 hours post administration of LY2216684

Population: Participants who received at least 1 dose of LY2216684 and had evaluable LY2216684 plasma concentration data were included in the analysis. Participants who vomited within twice the median time to maximum observed drug concentration (tmax) following dosing of LY2216684 were excluded from the analysis.

Blood samples were collected prior to and up to 120 hours following dosing of LY2216684 on Day 1 (Period 1) for the measurement of LY2216684 plasma concentrations.
