Pharmacokinetic Study To Evaluate Effect of Food and Diurnal Variation on ABT-869

Study Overview
=================
Brief Summary
-----------------
To estimate the effect of food on the oral bioavailability and effect of diurnal variation on the pharmacokinetics of ABT-869.

Detailed Description
-----------------
This study is a pharmacokinetic study designed to evaluate the effect of food on the oral bioavailability and effect of diurnal variation on the pharmacokinetics of ABT-869. Triplicate ECG performed to determine the effect of ABT-869 on QT prolongation . Subjects may continue receiving linifanib after completion of the study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetic | Blood samples for the pharmacokinetics of linifanib will be collected for each subject and each regimen (fasting, fed, AM and PM dosings). | Various timepoints | 
| ECG Evaluation | Triplicate ECG will be performed at designated timepoints. | Various timepoints | 
| Adverse Events | Only treatment emergent AEs will be included. Toxicity grade, relationship to study drug and AEs leading to discontinuation will be evaluated. | Throught the study | 
| Lab data and vital signs | Blood chemistry and hematology will be analyzed based on the regimen and dosing and overall. 24 hr ABPM will be analyzed by regimen and dosing time and overall. | Various timepoints |
