The Effect of Gemfibrozil, Ketoconazole and Clarithromycin on the Amount of LY2409021 in the Bloodstream

Eli Lilly and Company30 enrolled

Overview

The purpose of this study is to examine the effect of gemfibrozil, ketoconazole, and clarithromycin on how much LY2409021 is found in the bloodstream and how long the body takes to get rid of it. The study is split into two parts, Part A and Part B. Participants in Part A are divided into two cohorts (groups). Each cohort will participate in two study periods. Period 1 involves a single dose of LY2409021. Period 2 involves either gemfibrozil or ketoconazole given daily for 21 days with LY2409021 given once on Day 4. Part A will last for 51 days and will also involve screening within 27 days of the start of the study. Part B is only open to participants who successfully completed Part A of the study. Participants in Part B will receive clarithromycin given daily for 21 days with LY2409021 given once on Day 4. Part B will last for 29 days and will also involve screening within 27 days of the start of the study.

Part B was added to the trial in August 2013, per protocol amendment.
