Inclusion Criteria:

1. 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.

Note: It is not necessary that informed consent be obtained within the
protocol-specified screening window.

2. Age ≥ 18 years

3. Diagnosis of metastatic/unresectable renal cell carcinoma of the clear cell type or
with a component of clear cell histology

4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1

5. Measurable disease by RECIST criteria (Version 1.1)

6. Eligible patients must have been treated with sunitinib for a minimum of 12 weeks (2
cycles). Patients must have evidence of progressive disease following treatment with
sunitinib as assessed by the site investigator on the basis of CT scans and other
appropriate clinical documentation. Patients who received sunitinib for 12 weeks
(2cycles) but stopped the drug due to toxicity rather than disease progression are
also eligible for this study.

The Investigator should be aware of the patient's intolerance/toxicity with prior
sunitinib treatment and take this in to account when assessing eligibility for the
pazopanib study.

Patients who have had prior treatment with either temsirolimus or everolimus are also
eligible for the trial.

No other prior treatment with bevacizumab, sorafenib, immunotherapies, chemotherapy,
biologic therapy or investigational therapy is allowed.

Previous radiotherapy (RT) is permissible provided the measurable disease is outside
the RT port. RT must be completed > 2 weeks prior to registration.
