A Pharmacokinetic Study to Access How the Body Absorbs and Removes Linifanib in Male Patients With Advanced Solid Tumors.

Study Overview
=================
Brief Summary
-----------------
A pharmacokinetic study to access how the body absorbs and removes linifanib in male patients with advanced solid tumors.

Detailed Description
-----------------
This study is designed to assess the mass balance of [14C]linifanib and the metabolic profiles of linifanib in 4 subjects with advanced solid tumors following a single oral dose. Subjects may continue on linifanib after completion of the metabolism study. The results of this study will determine the exposure of major metabolites and excretion pathway(s) of the parent drug and metabolites of linifanib in humans.

Official Title

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetic Profile | Blood samples for the pharmacokinetics (PK) of linifanib will be collected at designated time points. | Various timepoints from Day 1 through approximately Day 9 | 
| Total radioactivity | Blood, urine, and fecal samples for total radioactivity analysis will be collected at designated time points. | Various timepoints from Day 1 through approximately Day 9 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety (Number of subjects with adverse events and/or dose-limiting toxicities) | Adverse event monitoring, lab test assessments, physical exam and vital signs will be evaluated throughout the study. | At each treatment visit (daily for first 9 days and then approximately every 4 weeks through end of treatment) |
