Testosterone in Treating Patients With Progressive Prostate Cancer That No Longer Responds to Hormone Therapy
- Conditions
- Prostate Cancer
- Registration Number
- NCT00006044
- Lead Sponsor
- Memorial Sloan Kettering Cancer Center
- Brief Summary
RATIONALE: High doses of testosterone may be effective in killing prostate cancer cells that no longer respond to hormone therapy.
PURPOSE: Phase I trial to study the effectiveness of testosterone in treating patients who have progressive prostate cancer that no longer responds to hormone therapy.
- Detailed Description
OBJECTIVES:
* Determine the safety and maximum tolerated dose of exogenously administered testosterone in patients with progressive androgen-independent prostate cancer who have been in castrate state either surgically or pharmacologically for a minimum of 1 year.
* Assess the changes in expression of androgen receptor and other receptors in human biopsy specimens or circulating tumor cells before and after this treatment in this patient population.
OUTLINE: This is a dose-escalation study.
Patients receive testosterone via an enhanced absorption transdermal system continuously for 28 days. The transdermal patches are changed daily.
Cohorts of 3-6 patients receive a fixed daily dose of testosterone with escalating duration of exposure until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicities.
Patients are followed at day 1 and at weeks 2 and 4.
PROJECTED ACCRUAL: A total of 3-18 patients will be accrued for this study.
