A Study of Evacetrapib (LY2484595) and Warfarin in Healthy Participants

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Eli Lilly and Company
ClinicalTrials.gov Identifier:
NCT01825876
First received: April 3, 2013
Last updated: June 27, 2013
Last verified: June 2013
  Purpose

All study participants will receive both warfarin and a study drug called evacetrapib. The main purpose of this study is to look at how much warfarin gets into the blood stream and how long it takes the body to get rid of warfarin when given both with and without evacetrapib. Another purpose is to evaluate the effectiveness of warfarin therapy to prevent blood clots when given with evacetrapib by measuring the time it takes for blood to clot and comparing it to an average of the international normalized ratio (INR). INR measures the time it takes for blood to clot and compares it to an average.

The study will last approximately 5 weeks, not including screening.

Primary Outcome Measures:
  • Pharmacokinetics (PK): Area Under the Concentration Curve (AUC) of S-Warfarin [ Time Frame: Baseline to 144 hours following warfarin dose on study days 1 and 17 ]
  • Pharmacokinetics (PK): Maximum Concentration (Cmax) of S-Warfarin [ Time Frame: Baseline to 144 hours following warfarin dose on study days 1 and 17 ]

Secondary Outcome Measures:
  • Pharmacokinetics (PK): Area Under the Concentration Curve (AUC) of R-Warfarin [ Time Frame: Baseline to 144 hours following warfarin dose on study days 1 and 17 ]
  • Pharmacokinetics (PK): Maximum Concentration (Cmax) of R-Warfarin [ Time Frame: Baseline to 144 hours following warfarin dose on study days 1 and 17 ]
  • Pharmacodynamics (PD): Area Under the International Normalized Ratio Curve (AUCINR) of Warfarin [ Time Frame: Baseline to 144 hours following warfarin dose on study days 1 and 17 ]
