Trial Information

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


I. To determine the efficacy of pazopanib (pazopanib hydrochloride) in non clear cell
metastatic renal cell cancer patients as assessed by the overall survival rate at 12 months.


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.


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.

used consistently and in accordance with both the product label and the

procedures or assessments, and must be willing to comply with treatment and

Outcome Description:

A "12-month overall survivor" will be considered synonymous with "success". The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated.

Outcome Time Frame:
