17-AAG in Treating Patients With Metastatic Prostate Cancer That Did Not

Status Completed

Clinical Trial Summary

This phase II trial is studying how well 17-AAG works in treating patients with metastatic prostate cancer that did not respond to previous hormone therapy. Drugs used in chemotherapy, such as 17-AAG, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. Determine the prostate-specific antigen (PSA) response in patients with hormone-refractory metastatic prostate cancer treated with 17-N-allylamino-17-demethoxygeldanamycin (17-AAG).

SECONDARY OBJECTIVES:

I. Determine the overall survival and disease-free survival rate in patients treated with this drug.

II. Determine the safety profile of this drug in these patients. III. Determine the duration of PSA response and PSA control in patients treated with this drug.

IV. Determine the partial and complete response rates in patients with measurable disease treated with this drug.

V. Correlate changes in expression levels of interleukin-6, maspin, and NF-kappaB in serum and tissue with cancer and treatment-related outcomes in patients treated with this drug.

OUTLINE: This is a multicenter study. Patients receive 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) IV over 2-6 hours on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients who achieve a complete response (CR) receive 2 additional courses of treatment beyond documentation of CR.

After completion of study treatment, patients are followed every 3 months for 1 year and then every 6 months for 3 years.

PROJECTED ACCRUAL: A total of 16-28 patients will be accrued for this study within 20 months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
