  Purpose

RATIONALE: Vandetanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vandetanib together with temozolomide may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of vandetanib and temozolomide in treating patients with advanced solid tumors that cannot be removed by surgery.

Estimated Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

  • To determine the maximum tolerated dose of concurrently administered vandetanib and temozolomide in patients with unresectable, advanced solid tumors.
  • To describe the toxicity profile of this regimen in these patients.
  • To describe the response rate in patients treated with this regimen.
  • To describe the effects of therapy on angiogenesis-related translational endpoints.

OUTLINE: Patients receive escalating doses of oral vandetanib once daily on days 1-28 and oral temozolomide once daily on days 1-5. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

Blood samples are collected at baseline and prior to each treatment course for correlative laboratory studies, including evaluation of plasma VEGF levels by ELISA, serum angiogenesis assay, and measurement of circulating endothelial cell populations (CD133, CD34, CD146). Frozen serum and plasma samples are also stored for future research studies.
