Kidney Cancer | Pazopanib Versus Temsirolimus in Poor-Risk Clear-Cell Renal Cell Carcinoma (RCC)

Kidney Cancer research study

What is the primary objective of this study?

The goal of this clinical research study is to compare pazopanib to temsirolimus in the treatment of advanced clear-cell renal cell carcinoma. The safety of each drug will also be studied. Pazopanib is designed to block the growth of blood vessels that supply nutrients needed for tumor growth. This may prevent or slow the growth of cancer cells. Temsirolimus is designed to block the growth of cancer cells, which may cause cancer cells to die. This is an investigational study. Pazopanib and temsirolimus are both FDA approved and commercially available for the treatment of kidney cancer. It is investigational to compare the 2 drugs. Up to 90 patients will be enrolled in this study. All will be enrolled at MD Anderson.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Pazopanib800 mg by mouth daily in 4 week study cycle.

Drug:Temsirolimus25 mg by vein infused over 30-60 minutes every week in 4 week study cycle.

Behavioral:Quality of Life AssessmentCompletion of full assessment battery at baseline, prior to treatment then every 8 weeks at clinical evaluation.

Drug:Benadryl25 to 50 mg by vein approximately 30 minutes before the start of each dose of temsirolimus.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
