Primary Outcome Measures:
  • activity of trilostane in men with androgen-independent prostate cancer. [ Time Frame: 4 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • serum levels of gonadal and adrenal steroids [ Time Frame: 4 years ] [ Designated as safety issue: No ]

Enrollment: 24
Study Start Date: March 2004
Study Completion Date: January 2006
Primary Completion Date: January 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Trilostane
    Taken orally once a day for three days then twice daily thereafter.
    Drug: Hydrocortisone
    Taken orally with trilostane.
Detailed Description:
  • Patients will take trilostane orally once a day for three days, then twice a day thereafter.
  • Patients will complete a daily drug log recording the date, time and number of capsules taken.
  • Trilostane may moderately decrease the production of steroids by the adrenal glands. In order to prevent any symptoms related to decreased steroid production, patients will also take hydrocortisone at the same time as the trilostane.
  • While the patients are on treatment blood work will be done after 2 weeks and then every 4 weeks to test the levels of PSA in the blood. On weeks 4 and 8 of treatment additional blood work will be done to check hormone levels. Blood pressure and pulse rate will also be taken every 4 weeks.
  • Depending upon disease status, radiological testing (CT scan, x-rays, and/or bone scan) may be repeated every 12 weeks.
  • Patients will remain on study treatment as long as their disease responds and they do not experience any severe side effects.
