Summary

The purpose of this study is to determine the highest safe dose of XL184 administered orally in combination with temozolomide (TMZ, Temodar®) and radiation therapy (RT). XL184 is a new chemical entity that inhibits VEGFR2, MET, and RET, kinases implicated in tumor formation, growth and migration. Temozolomide (TMZ, Temodar®) is an orally administered alkylating agent. It is approved by the Food and Drug Administration (FDA) for the treatment of newly diagnosed glioblastoma (GB) patients when given in combination with radiation therapy (RT) followed by maintenance treatment. First-line treatment for patients with GB consists of a concurrent phase (6-7 weeks in duration) during which TMZ is given with RT, followed by a rest phase (4 weeks in duration; to allow for recovery from delayed toxicity, if present), and a maintenance phase, during which patients receive TMZ for approximately twelve 28-day cycles. To determine the highest safe dose, subjects will receive different amounts of XL184 at different times according to the phase of TMZ and radiation therapy. The first group of subjects will receive the lowest dose of XL184. As long as no medically unacceptable side effects are noted, the dose will be increased for the next group. If the dose is not well-tolerated by the first group of subjects, the dose will be lowered for the next group.
