Sunitinib Malate Before and After Surgery in Treating Patients With Previously Untreated Metastatic Kidney Cancer

Overview

RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving sunitinib malate before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving sunitinib malate after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial is studying how well giving sunitinib malate before and after surgery works in treating patients with metastatic kidney cancer.

    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: August 2010

Detailed Description

OBJECTIVES:

Primary

- Determine if neoadjuvant sunitinib malate can achieve a clinical benefit of 70% or more to the primary renal tumor prior to surgery and adjuvant sunitinib malate in patients with metastatic renal cancer.

Secondary

- Determine the time to radiological progression in these patients.

- Determine the overall survival of these patients.

- Determine the proportion of patients suitable for nephrectomy after neoadjuvant sunitinib malate.

- Determine the translational endpoints.

OUTLINE: Patients receive oral sunitinib malate once daily on days 1-28. Treatment repeats every 6 weeks for 3 courses. Approximately 2 weeks later, patients undergo a standard radical nephrectomy with lymph node dissection. Beginning at least 2 weeks after surgery, patients receive oral sunitinib malate on days 1-28. Courses repeat every 6 weeks in the absence of disease progression or unacceptable toxicity.

Blood and tissue samples may be collected periodically for laboratory studies.

After completion of study treatment, patients are followed every 2 months.

Interventions

  • Drug: sunitinib malate
  • Other: laboratory biomarker analysis
  • Procedure: adjuvant therapy
  • Procedure: neoadjuvant therapy
  • Procedure: therapeutic conventional surgery

Participating in This Clinical Trial

DISEASE CHARACTERISTICS:

  • Histologically confirmed renal cell carcinoma
  • Measurable metastatic disease on CT/MRI imaging
  • Patients with suspicion of renal cancer on radiology must have a biopsy to confirm diagnosis of clear cell disease
  • No prior therapy for renal cancer
  • Judged by the treating physician to have the potential to derive clinical benefit from this treatment

PATIENT CHARACTERISTICS:
