Primary Outcome Measures

Name	Time	Method
Main Objective: Phase I: To determine the dose of pioglitazone to be used in phase II and to obtain pharmacokinetic data about sorafenib and pioglitazone for the investigated treatment regimen<br><br>Phase II: to determine progression-free survival<br>•Progression-free survival (primary objective) is defined as the time interval between the date of study entry and the date of progression, the date of death, or the date of last follow-up, with progression or death treated as target event. <br>;Secondary Objective: •To evaluate overall response rate.<br>•To evaluate time to tumor response.<br>•To evaluate overall survival.<br>•To evaluate quality of life.<br>•To evaluate tolerability and safety.<br>;Primary end point(s): Progression-free survival (PFS). PFS is defined as the time interval between the date of study entry and the date of progression, the date of death, or the date of last follow-up, with progression or death treated as target event.
