including, but not limited to: active peptic ulcer disease, known intraluminal
metastatic lesion/s with risk of bleeding inflammatory bowel disease (e.g.,
ulcerative colitis, Crohn's disease), or other GI conditions with increased risk of
perforation, history of abdominal fistula, GI perforation, or intra abdominal abscess
within 28 days prior to beginning study treatment.

product including, but not limited to: malabsorption syndrome, major resection of the
stomach or small bowel.

bypass graft surgery, symptomatic peripheral vascular disease, Class III or IV congestive
heart failure, as defined by the New York Heart Association (NYHA).

- Poorly controlled hypertension Note: Initiation or adjustment of antihypertensive
medication(s) is permitted prior to study entry.

- History of cerebrovascular accident including transient ischemic attack, pulmonary
embolism or untreated deep venous thrombosis (DVT) within the past 6 months. Note:
Subjects with recent DVT who have been treated with therapeutic anti-coagulating
agents for at least 6 weeks are eligible.

study drug.

- 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.

- Treatment with any of the following anti-cancer therapies: radiation therapy, surgery
or tumor embolization within 14 days prior to the first dose of pazopanib OR
chemotherapy, immunotherapy, biologic therapy, investigational therapy or hormonal
therapy within 14 days or 5 half-lives of a drug (whichever is longer) prior to the
first dose of pazopanib.

- Any ongoing toxicity from prior anti-cancer therapy that is > Grade 1 (graded by

days or 5 half- lives of a drug (whichever is longer) prior to the first dose of study
drug and for the duration of the study.

-Use of HRT prior to study enrollment due to the potential for inhibition of cytochrome
P450 enzymes that metabolize estrogens and progestins (Arm A female subjects only).
