Study of Multiple Doses and Regimens of XL184 (Cabozantinib) in Subjects With Grade IV Astrocytic Tumors in First or Second Relapse

28 de julio de 2014 actualizado por: Exelixis

A Phase 2 Non-Comparative Randomized Open-Label Study of Multiple Regimens of Single-Agent XL184 in Subjects With Grade IV Astrocytic Tumors in First or Second Relapse

This is a study of multiple regimens of single-agent XL184 in subjects with grade IV astrocytic tumor in first or second relapse. The Randomized Phase of the study will evaluate the safety, tolerability, and preliminary efficacy of four XL184 dosing regimens in separate study arms. Subjects will be randomized to one of the study arms, which will not be blinded. After the Randomized Phase, additional subjects will be enrolled to further expand one study arm in the Expansion Phase.
