NCT00385853
PTK is an investigational new drug that has been shown in early laboratory studies to prevent the formation of new blood vessels that allow the tumor to grow. These studies have shown that the study drug can potentially improve the effectiveness of additional radiation and chemotherapy. With this study, we would like to examine the effects of PTK when used in combination with radiation therapy and the anti-cancer drug temozolomide, the standard treatment for patients with newly diagnosed glioblastoma. We would also like to learn how the study drug is absorbed, distributed, and cleared from the body.
NCT00704080
The purpose of this study is to determine the safety and tolerability of XL765 in combination with Temozolomide in adults with anaplastic gliomas or glioblastoma on a stable Temozolomide maintenance dose. XL765 is a new chemical entity that inhibits the kinases PI3K and mTOR. In preclinical studies, inactivation of PI3K has been shown to inhibit growth and induce apoptosis (programmed cell death) in tumor cells, whereas inactivation of mTOR has been shown to inhibit the growth of tumor cells. Temozolomide (TMZ, Temodar®) is an orally administered alkylating agent with activity against malignant gliomas. It is approved by the Food and Drug Administration for the following indications: 1) treatment of newly diagnosed glioblastoma multiforme (GBM) patients when given concomitantly with radiotherapy and then as maintenance treatment; 2) refractory anaplastic astrocytoma (AA), ie, patients who have experienced disease progression on a drug regimen containing nitrosourea and procarbazine. Temozolomide is commonly used in the treatment of other anaplastic gliomas (AG) including oligodendroglial tumors and mixed gliomas.
