Conditions: Carcinoma, Renal Cell
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 317
Healthy volunteers: no

Brief summary:
This trial has two parts. The purpose of the first part of the trial is to determine the doses of 2 drugs, sunitinib malate and interferon alfa-2b, that can be given safely in combination. This part is currently closed to enrollment.

The purpose of the second part of the trial is to see if sunitinib malate given on a 4/2 schedule (4 weeks on treatment, 2 weeks off treatment cycle) is any better at delaying progression of renal cell cancer than sunitinib malate given on a continuous dosing schedule. The trial will also determine the number of patients whose cancer responds to the treatments, whether life of patients can be extended, what the side effects are of the treatments, how bothersome disease or treatment-related symptoms are to patients, and whether tests can be found that will predict which patients may or may not respond to these treatments in the future.
