A Study to Evaluate Pazopanib as an Adjuvant Treatment for Localized Renal Cell Carcinoma (RCC)

Inclusion Criteria:

Signed written informed consent
Diagnosis of RCC with clear-cell or predominant clear-cell histology

Subjects with non-metastatic disease (M0) fulfilling any of the following combinations of pathologic staging based on American Joint Committee on Cancer (AJCC) TNM staging version 2010 and Fuhrman nuclear grading.

pT2, G3 or G4, N0; or,
pT3, G any, N0; or,
pT4, G any, N0; or,
pT any, G any, N1

Fulfill all of the following criteria of disease-free status at baseline:

Had complete gross surgical resection of all RCC via radical or partial nephrectomy using either open or laparoscopic technique.
Baseline imaging of chest, abdomen and pelvis shows no metastasis or residual tumor lesions as confirmed centrally by an independent radiologist.
Received no prior adjuvant or neo-adjuvant treatment for RCC
Recovered from nephrectomy: any surgery related toxicities should be reduced to ≤ grade 1 per NCI Common Terminology Criteria for Adverse Events (CTCAE) (Version 4)
Karnofsky performance scale (KPS) of ≥ 80
Adequate organ system function

Exclusion Criteria:

History of another malignancy. Exception: Subjects who have had another malignancy and have been disease-free for 5 years, or subjects with a history of completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma are eligible

Clinically significant gastrointestinal abnormalities that may increase the risk for gastrointestinal bleeding including, but not limited to:

Active peptic ulcer disease
Inflammatory bowel disease (e.g. ulcerative colitis, Crohn's disease), or other gastrointestinal conditions with increased risk of perforation
History of abdominal fistula, gastrointestinal perforation, or intra abdominal abscess within 28 days prior to beginning study treatment
Active diarrhea of any grade

Clinically significant gastrointestinal abnormalities that may affect absorption of investigational product including, but not limited to:

Malabsorption syndrome
Major resection of the stomach or small bowel
History of human immunodeficiency virus (HIV) infection
History of active hepatitis
Presence of uncontrolled infection.

History of any one or more of the following cardiovascular conditions within the past 6 months:

Cardiac angioplasty or stenting
Myocardial infarction
Unstable angina
Coronary artery bypass graft surgery
Symptomatic peripheral vascular disease
History of Class III or IV congestive heart failure, as defined by the New York Heart Association Classification of Congestive Heart Failure
History of cerebrovascular accident including transient ischemic attack (TIA), pulmonary embolism or untreated deep venous thrombosis (DVT) within the past 6 months.
Corrected QT interval (QTc) > 480 milliseconds (msec)
Poorly controlled hypertension, defined as systolic blood pressure (SBP) of ≥140 mmHg or diastolic blood pressure (DBP) of ≥ 90mmHg.

Note: Initiation or adjustment of antihypertensive medication(s) is permitted prior to study entry. Blood pressure (BP) must be re-assessed on two occasions that are separated by a minimum of 1 hour; on each of these occasions, the mean (of 3 readings) SBP / DBP values from each BP assessment must be <140/90 mmHg in order for a subject to be eligible for the study (see Section 7.6.2 for instruction on blood pressure measurement and obtaining mean blood pressure values).

Evidence of active bleeding or bleeding diathesis
Any serious and/or unstable pre-existing medical, psychiatric, or other condition that could interfere with subject's safety, provision of informed consent, or compliance to study procedures
Unable or unwilling to discontinue use of prohibited medications for at least 14 days or five half-lives of a drug (whichever is longer) prior to the first dose of study treatment and for the duration of the study.
Concurrent therapy given to treat cancer including treatment with an investigational agent or concurrent participation in another clinical trial involving anti-cancer investigational drug.
Administration of an investigational drug within 30 days or 5 half-lives, whichever is longer, preceding the first dose of study treatment.
Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to pazopanib or excipients that in the opinion of the investigator contraindicates their participation.
Prior or current use of systemic anti-VEGF inhibitors, cytokines (e.g. interferon, interleukin 2).
