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.
- 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.
Primary Purpose: Treatment

Tumors or cancer of the PROSTATE which can grow in the presence of low or residual amount of androgen hormones such as TESTOSTERONE.
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Steroidal compounds related to TESTOSTERONE, the major mammalian male sex hormone. Testosterone congeners include important testosterone precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with androgenic activities.
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
