Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase II trial studies how well pazopanib hydrochloride works in treating patients with advanced or progressive malignant pheochromocytoma or paraganglioma. 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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To assess the anti-tumor activity (in terms of the tumor response rate using the Response Evaluation Criteria in Solid Tumors \[RECIST\] criteria) of pazopanib (pazopanib hydrochloride) (GW786034) in patients with advanced malignant pheochromocytomas and paragangliomas.

SECONDARY OBJEC TIVES:

I. To assess safety profile of pazopanib. II. To assess duration of tumor response. III. To assess time to treatment failure. IV. To assess progression-free survival time. V. To assess overall survival time.

TERTIARY OBJECTIVES:

I. For patients with secretory tumors, to examine changes in urinary catecholamine and/or metanephrine levels.

II. For patients with secretory tumors, to examine whether pazopanib-induced changes in urinary catecholamine and/or metanephrine levels during the first cycle of treatment may be associated with objective tumor response.

III. To examine associations between tumor response and somatic mutational status in archived tumors, or germline mutational status in patient's peripheral blood mononuclear cells, (presence of succinate dehydrogenase complex subunit D \[SDHD\], succinate dehydrogenase complex subunit B \[SDHB\], ret proto-oncogene \[RET\], von Hippel-Lindau tumor suppressor \[VHL\], neurofibromatosis type-1).

IV. To examine associations between tumor response and tumor expression levels of angiogenic and vascular markers including hypoxia inducible factor 1, alpha (HIF-1a), vascular endothelial growth factor receptor (VEGF-R) (total and phospho-) and microvessel density in archival tumor tissue.

IV. To examine whether the extent of tumor response/regression may be correlated with plasma pazopanib (GW786034) concentration achieved after the third cycle (first cycle after run-in cycles) of pazopanib (GW786034) therapy.

OUTLINE:

Patients receive pazopanib hydrochloride orally (PO) once daily (QD) on days 1-28 (days 1-14 of courses 1 and 2). Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients undergo urine and blood sample collection at baseline and periodically during study for correlative studies.

After completion of study therapy, patients are followed up every 3-6 months for up to 5 years.

* Total bilirubin =\< 1.5 x institutional upper limit of normal (ULN) (except in cases of Gilbert's syndrome, where indirect bilirubin may be elevated, but the direct bilirubin remains within 1.5 x ULN)
* Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 x ULN
* NOTE: Subjects who have both bilirubin \> ULN and AST/ALT \> ULN are not eligible
* Alkaline phosphatase =\< 2.5 x ULN
* Creatinine =\< 1.5 mg/dL (133 umol/L) or within normal institutional limits OR creatinine clearance \>= 50 mL/min/1.73m\^2 for subjects with creatinine levels about institutional normal
