Von Hippel-Lindau Disease Clinical Trial
Pazopanib Hydrochloride in Treating Patients With Von Hippel-Lindau Syndrome
This phase II trial studies the side effects and how well pazopanib hydrochloride works in treating patients with von Hippel-Lindau syndrome. Pazopanib hydrochloride may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
I. Evaluate safety and efficacy of treatment with pazopanib hydrochloride (pazopanib) for 6 months in patients with von Hippel-Lindau syndrome (VHL) who have a measurable VHL related lesion.
I. Evaluate rate of growth over time in target lesions before and after pazopanib treatment.
II. Evaluate need for surgical intervention over time in patients who receive pazopanib and compare to rate prior to receipt of drug.
III. Create an annotated tissue resource from patients with VHL for use in future research related to cancer.
I. Evaluate circulating factors in patients with VHL undergoing treatment with pazopanib.
II. Evaluate relationship between VHL genotype and response to pazopanib.
Patients receive pazopanib hydrochloride orally (PO) once daily (QD) on days 1-28. Treatment repeats every 4 weeks for up to 24 weeks in the absence of disease progression or unacceptable toxicity. Patients benefitting from treatment may continue pazopanib hydrochloride in the absence of disease progression.
After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 24 weeks.
Subjects must provide written informed consent prior to performance of study-specific procedures or assessments, and must be willing to comply with treatment and follow up; procedures conducted as part of the subject's routine clinical management (e.g., blood count, imaging study) and obtained prior to signing of informed consent may be utilized for screening or baseline purposes provided these procedures are conducted as specified in the protocol
