About

RATIONALE: Interferon alfa may interfere with the growth of tumor cells and slow the growth of kidney cancer.

PURPOSE: This phase II trial is studying how well interferon alfa works in treating patients with metastatic kidney cancer.

Full description

OBJECTIVES:

Primary

• Determine the objective response rate in patients with metastatic renal clear cell carcinoma treated with interferon alfa-1b.

Secondary

• Determine the toxicity of this drug in these patients.

OUTLINE: This is an open-label study.

Patients receive interferon alfa-1b subcutaneously daily. Treatment continues in the absence of unacceptable toxicity or disease progression.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.

Enrollment: 7 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
