Pazopanib Hydrochloride in Treating Young Patients With Solid Tumors That Have Relapsed or Not Responded to Treatment
This phase I trial is studying the side effects and best dose of pazopanib hydrochloride in treating young patients with solid tumors that have relapsed or not responded to treatment. Pazopanib hydrochloride 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.

|Official Title:||A Phase I Study of Pazopanib as a Single Agent for Children With Relapsed or Refractory Solid Tumors|
- Maximum-tolerated dose of pazopanib hydrochloride defined as the maximum dose at which fewer that one-third of patients experience DLT [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]Graded using the NCI CTCAE version 4.0.
- Adverse events according to NCI CTCAE version 4.0 [ Time Frame: Up to 30 days after completion of study treatment ] [ Designated as safety issue: Yes ]
- Pharmacokinetics of pazopanib hydrochloride [ Time Frame: Baseline, days 15, 22, and 27 of course 1 and day 1 of odd courses ] [ Designated as safety issue: No ]Summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).
- Overall response to pazopanib hydrochloride according to RECIST criteria [ Time Frame: Up to 30 days after completion of study treatment ] [ Designated as safety issue: No ]The overall response assessment takes into account response in both target and non-target lesions, the appearance of new lesions and normalization of markers.
|Study Start Date:||June 2009|
|Primary Completion Date:||April 2013 (Final data collection date for primary outcome measure)|
Experimental: Treatment (pazopanib hydrochloride)
Patients receive oral pazopanib hydrochloride once daily on days 1-28. Courses repeat every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity.

I. Estimate the maximum-tolerated dose and/or recommended phase II dose of pazopanib hydrochloride in pediatric patients with relapsed or refractory solid tumors.
II. Define and describe the toxicities of this regimen in these patients. III. Characterize the pharmacokinetics of pazopanib hydrochloride in these patients.
I. Preliminarily define the antitumor activity of pazopanib hydrochloride within the confines of a phase I study.
II. Evaluate changes in tumor vascular permeability following initiation of pazopanib hydrochloride and correlate these changes with clinical outcome by dynamic contrast-enhanced MRI.
OUTLINE: This is a multicenter study dose-escalation study.
Patients receive oral pazopanib hydrochloride once daily on days 1-28. Courses repeat every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity. Patients accrued after the maximum-tolerated dose (MTD) of pazopanib hydrochloride has been determined receive pazopanib hydrochloride as an oral suspension.
Some patients undergo dynamic contrast-enhanced MRI at baseline and periodically during study. Blood samples are collected at baseline and periodically during study for pharmacokinetic studies.
