17-N-Allylamino-17-Demethoxygeldanamycin in Treating Patients With Metastatic Kidney Cancer

OBJECTIVES:

Primary

• Determine the efficacy of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) in patients with metastatic papillary or clear cell renal cell carcinoma.

Secondary

• Determine the safety of this drug in these patients.
• Correlate tumor c-met expression with response in patients treated with this drug.

OUTLINE: This is an open-label study. Patients are stratified according to histology (papillary vs clear cell).

Patients receive 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) IV over 60-90 minutes on days 1, 4, 8, and 11. Treatment repeats every 21 days for up to 1 year in the absence of disease progression or unacceptable toxicity.

Patients are followed at 3 weeks and then every 3 months thereafter.

PROJECTED ACCRUAL: A total of 24-74 patients (12-37 per stratum) will be accrued for this study within 6-20 months (clear cell stratum) and 2-5 years (papillary stratum).
