  Purpose

The purpose of this study it to learn the effects (good or bad) that rosiglitazone has on patients and their prostate cancer. This study is going to look at what effects rosiglitazone has on prostate specific antigen (PSA) levels.

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • To evaluate the activity of rosiglitazone by comparing changes in PSA doubling time between rosiglitazone-treated and placebo-treated men. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Evaluate time to PSA progression as a measure of the activity of rosiglitazone. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Enrollment: 100
Study Start Date: September 2000
Study Completion Date: August 2003
Primary Completion Date: August 2003 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Group 1 Drug: Rosiglitazone
Given orally twice daily. Participants may continue study treatment as long as their disease does not progress and they don't experience any serious side effects.
Other Name: Avandia
Placebo Comparator: Group 2 Other: Placebo
Given orally twice daily.

Detailed Description:
  • Patients will be randomly assigned to initial treatment with either rosiglitazone or placebo orally twice daily, every day as long as there is no disease progression or serious side effects. Patients will be asked to complete a drug log to keep track of the medication.
  • Before treatment begins the following tests will be performed: physical exam; bone scan; blood work (including PSA level test) and a urine sample.
  • While on this study the following tests and procedures will be done once a month: review of side effects and routine blood tests (including PSA levels).
  • While on this study the following tests and procedures will be done on months 2 and 4: review of side effects; routine blood tests (including PSA levels) and urine tests.
  • If the patient's disease progressed the treatment code will be broken and if the patient was on placebo, they will have the option to begin taking rosiglitazone.
