Brief Summary

The study will evaluate how genetic profiles respond to LY2216684 and the effect of Quinidine on the pharmacokinetics (PK) of LY2216684 in a specific genetic profile. Side effects will be documented.

Detailed Description

The human cytochrome P450 2C19 (CYP2C19) enzyme is a polymorphic enzyme yielding ultrarapid metabolizer, extensive metabolizer (EM), intermediate metabolizer, and poor metabolizer (PM) phenotypes. Enrollment in the study was limited to participants predicted to be CYP2C19 extensive metabolizers or CYP2C19 poor metabolizers, as determined by genotyping analysis.

Study Groups

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.

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.
