- I. To determine the safe phase II dose of this novel regimen. (Phase I)
- II. To determine the median progression free survival (PFS) from this novel regimen. (Phase II)
I. To evaluate the safety and toxicity of the proposed regimen. (Phase I) II. To evaluate the response rate. (Phase I) III. To evaluate the pharmacokinetics of pazopanib (pazopanib hydrochloride). (Phase I) IV. To evaluate the vascular endothelial growth factor (VEGF) levels and myeloid derived suppressor cell (MDSC) levels at various time points and correlate with response. (Phase I) V. To evaluate the safety and toxicity of this new regimen. (Phase II) VI. To evaluate the VEGF levels, interleukin (IL)-8 levels and MDSC levels at various time points and correlate with outcome. (Phase II) VII. To evaluate the PFS rate at 12 months. (Phase II) VIII. To evaluate overall survival. (Phase II)
OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.
Patients receive pazopanib hydrochloride orally (PO) on days 1-28, and bevacizumab intravenously (IV) over 30-90 minutes on days 36 and 50. Courses repeat every 70 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and Phase II patients are followed up by telephone every 12 months

Experimental: Treatment (pazopanib hydrochloride and bevacizumab)

Other: Laboratory Biomarker Analysis
Drug: Pazopanib Hydrochloride
Other: Pharmacological Study
- Median PFS (Phase II) [ Time Frame: Up to 30 days post-treatment ]Distributions of continuous variables will be summarized with commonly used statistics (mean, standard deviation, median, etc.), with sub-group associations tested using the Wilcoxon Rank Sum test.
- Optimal phase II dose, defined as the largest dose level at which less than 2 out of the 6 patients experienced dose-limiting toxicity, graded according to Common Terminology Criteria for Adverse Events version 4.0 (Phase I) [ Time Frame: Up to 140 days ]The frequency of toxicities will be tabulated for the dose estimated to be the maximum-tolerated dose.
- Incidence of grade 3 or higher toxicities, graded according to CTCAE version 4.0 [ Time Frame: Up to 30 days post-treatment ]Categorical variables will be summarized in contingency tables, with associations of interest assessed using Fisher's exact test. The frequency of toxicities will be tabulated by grade across all dose levels and courses.
- Overall survival (Phase II) [ Time Frame: From the date of study enrollment to the date of death from any cause, assessed up to 30 days post-treatment ]Will be obtained using Kaplan-Meier and Proportional Hazards methods.
- PFS rate at 12 months (Phase II) [ Time Frame: At 12 months ]Distributions of continuous variables will be summarized with commonly used statistics (mean, standard deviation, median, etc.), with sub-group associations tested using the Wilcoxon Rank Sum test.
- Response rate according to RECIST 1.1 (Phase I) [ Time Frame: Up to 30 days post-treatment ]
- IL-8 levels [ Time Frame: Up to 30 days post-treatment ]Distributions of continuous variables will be summarized with commonly used statistics (mean, standard deviation, median, etc.), with sub-group associations tested using the Wilcoxon Rank Sum test.
- MDSC levels [ Time Frame: Up to 30 days post-treatment ]
- Pazopanib exposure as measured by pharmacokinetics parameters [ Time Frame: Course 1 on day 1 at pre-dose, 2 hours, and 4 hours post-dose; day 15 at pre-dose and 2 hours post-dose; and day 29 ]
- VEGF levels [ Time Frame: Up to 30 days post-treatment ]
