A Randomised, Double-blind, Placebo Controlled, Multi-center Phase III Study to Evaluate the Efficacy and Safety of Pazopanib (GW786034) Compared to Placebo in Patients With Locally Advanced and/or Metastatic Renal Cell Carcinoma

Inclusion Criteria:

A patient will be considered for inclusion in this study only if all of the following
criteria apply:

- Signed written informed consent.

- Diagnosis of clear cell RCC that is predominantly clear cell histology. Note:
cytology cannot be the only pathologic criteria to confirm clear cell RCC. Patients
with tumor types that are interpreted as non-clear cell, e.g. papillary, are

- Locally advanced RCC (defined as disease not amenable to curative surgery or
radiation therapy) or metastatic RCC (equivalent to Stage IV RCC according to
American Joint Committee on Cancer (AJCC) staging.

- Note: If the metastatic disease is restricted to a solitary lesion, its neoplastic
nature must be confirmed by histology or cytology. Cytology cannot be the only
pathologic criteria to confirm clear cell RCC, but can be used in a patient with
histologically confirmed clear cell RCC to confirm that metastatic disease is
neoplastic in nature.

- Must have measurable disease, i.e. presenting with at least one measurable lesion per
Response Evaluation Criteria in Solid Tumors (RECIST). A measurable lesion is defined
as a lesion that can be accurately measured in at least one dimension with the
longest diameter ≥ 20 mm using conventional techniques, or ≥ 10 mm with spiral CT

- Note: Patient should be excluded if all baseline measurable lesions are within
previously irradiated areas.

- Note: A patient must complete all the baseline disease assessments in order to be
eligible. Baseline head, chest, abdominal and pelvic CT or MRI scans must be
performed within 2 weeks prior to the first dose of study medication; baseline bone
scan must be performed within 3 weeks of the first dose of study medication.

- Patients who have received only one prior systemic treatment for locally advanced or
metastatic RCC with documented disease progression or documented treatment
discontinuation due to unacceptable toxicity. This first-line systemic treatment must
be cytokine based.

- Note: The first-line cytokine-based treatment can be interleukin-2 (IL-2) or
interferon-α (INFα) monotherapy, IL-2 in combination with INF-α, IL-2 and/or INF-α in
combination with chemotherapy, hormonal or other therapies excluding agents targeting
angiogenesis pathways. Agents in a combination regimen can be given sequentially if
the treatment sequence is pre-determined and the patient does not fail one agent
prior to starting another.

- Note: Prior adjuvant or neo-adjuvant therapies are permitted excluding any agents
that target vascular endothelial growth factor (VEGF) or VEGF receptors. The
adjuvant/neo-adjuvant therapies should not be considered as first-line systemic
treatment for advanced RCC.


- Patients who have received no prior systemic therapy for advanced/metastatic RCC can
be enrolled if under any of the following circumstances:

- Patients who live in countries or regions where there is no established standard
first-line therapy for advanced/metastatic RCC or where there are barriers to the
access of established therapies such as sunitinib, sorafenib, IFNα or IL-2.

- Patients who live in countries or regions where IL-2 or INF-α has been approved for
the treatment of advanced/metastatic RCC, however, these agents are generally not
recognized by the local clinical community as a standard treatment for
advanced/metastatic RCC, or where the physician and the patient have determined that
the available cytokine therapies are not an acceptable therapeutic option.

- Patients who have recurred following prior adjuvant or neo-adjuvant cytokine therapy
for RCC are eligible to participate without receiving a first-line systemic treatment
for locally advanced or metastatic RCC. These patients should be stratified as the
first-line population.

- Male or female ≥ 18 years of age.

- A woman is eligible to participate in the study if she is of:

- Non-childbearing potential (i.e., physiologically incapable of becoming pregnant),
including any female who:

- Has had a hysterectomy,

- Has had a bilateral oophorectomy (ovariectomy),

- Has had a bilateral tubal ligation,

- Is post-menopausal (total cessation of menses for ≥1 year).

- Childbearing potential, has a negative serum pregnancy test within 2 weeks of the
first dose of study medication, and agrees to use adequate contraception. GSK
acceptable contraceptive methods, when used consistently and in accordance with both
the product label and the instructions of the physician, are as follows:

- An intrauterine device with a documented failure rate of less than 1% per year.

- Vasectomized partner who is sterile prior to the female patient's entry and is the
sole sexual partner for that female.

- Complete abstinence from sexual intercourse for 14 days before exposure to
investigation product, through the clinical trial, and for at least 21 days after the
last dose of investigational product.

- Double-barrier contraception (condom with spermicidal jelly, foam suppository, or
film; diaphragm with spermicide; or male condom and diaphragm with spermicide).

- Oral contraceptives are not reliable due to the potential for drug-drug interactions.

- A man with a female partner of childbearing potential is eligible to enter and
participate in the study if he is abstinent or uses a barrier method of contraception
during the study.

- Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0 or 1

- Adequate baseline organ function defined as:

- Hematologic function:

Absolute Neutrophil Count (ANC) ≥1 x 10^9/L Hemoglobin ≥ 9 g/dL Platelet ≥75 x 10^9/L

- Hepatic function:

Total bilirubin ≥ 1.5 x Upper Limit of Normal (ULN) Aspartate Aminotransferase (AST) and
Alanine Aminotransferase (ALT) ≥ 2 x ULN

- Renal function:

Calculated creatinine clearance≥30 mL/min [See Section 14.6 Appendix 6] and

≥Urine protein is 0, trace, or +1 determined by dipstick urinalysis, or < 1.0 gram
determined by 24-hour urine protein analysis.

- Note: A patient should first be screened with dipstick urinalysis. If urine protein
is ≥2+, then a 24-hour urine protein must be assessed and patient will be excluded if
24-hour urine protein is≥ 1.0 gram.

- Corrected serum calcium level within normal range per local clinical laboratory

Note: Patients with hypercalcemia should be treated until the corrected serum calcium
level reaches the normal range.

- At least 4 weeks must have elapsed since the last surgery and 2 weeks must have
elapsed since radiotherapy or the last systemic cytokine therapy.

- Complete recovery from prior surgery, and/or reduction of all AEs to Grade 1 from
prior systemic therapy or radiotherapy.

- Note: In patients with prior radiotherapy, the steroid doses should be stable or
decreasing for at least 2 weeks.

Exclusion Criteria:

A patient will not be eligible for inclusion in this study if any of the following
criteria apply:

- Pregnant or lactating female.

years, or patients with a history of completely resected non-melanomatous skin
carcinoma or successfully treated in situ carcinoma are eligible.
