A Two-way Crossover Study Of The Effect Of Food On The Pharmacokinetics Of Pazopanib In Cancer Patients

Study Overview
=================
Brief Summary
-----------------
This is two-part study (Part I/Part II). Part I is designed to determine the effect of a low and high fat meal on the pharmacokinetics of single dose pazopanib (GW572016). Part II is designed to allow patients continued access to study drug in a multiple dosing regimen. Patients who are receiving clinical benefit on that regimen will go into the long term rollover study VEG105430 provided they are stable for 8 weeks.
