Pazopanib Hydrochloride in Treating Patients With Metastatic Kidney Cancer

A Phase II Efficacy Trial of Pazopanib in Non-clear Cell Metastatic Renal Cell Cancer (mRCC) PINCR


Lead Sponsor: Mayo Clinic

Collaborator: National Cancer Institute (NCI)

Source Mayo Clinic
Brief Summary

This phase II trial studies how well pazopanib hydrochloride works in treating patients with kidney cancer that has spread to other places in the body (metastatic). Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Pazopanib hydrochloride may also stop the growth of kidney cancer by blocking blood flow to the tumor.

Detailed Description

PRIMARY OBJECTIVES: I. To determine the efficacy of pazopanib hydrochloride (pazopanib) in non clear cell metastatic renal cell cancer patients as assessed by the overall survival rate at 12 months. SECONDARY OBJECTIVES: I. To determine the rates of best tumor response at the end of the first two treatment cycles of pazopanib in non clear cell metastatic renal cell cancer patients. II. To determine the benefit of pazopanib in increasing progression free survival time. III. To describe toxicity profile of pazopanib in non clear cell metastatic renal cell cancer patients. OUTLINE: Patients receive pazopanib hydrochloride orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 2 years.

acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of the physician, are as follows: - Complete abstinence from sexual intercourse for 14 days before exposure to investigational product, through the dosing period, and for at least 21 days after the last dose of investigational product - Oral contraceptive, either combined or progesterone alone - Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure rate of less than 1% per year - Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject - Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository) - 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;
