This study is designed to explore the drug interaction between rifampin and linifanib to determine the potential effect of rifampin on the metabolism of linifanib. Linifanib will be taken alone or in combination with rifampin. The safety of a single dose administration of linifanib when administered alone and in combination with rifampin will be assessed. Subjects may enroll in a separate extension study to continue receiving linifanib after completion of this study.
This is a phase 1, open-label study designed to determine the interaction of rifampin with linifanib.
