Rosiglitazone (Avandia) vs Placebo for Androgen-Dependent Prostate Cancer

Information source: Memorial Sloan-Kettering Cancer Center
Information obtained from ClinicalTrials.gov on June 01, 2007
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Prostate Cancer

Intervention: Rosiglitazone (Avandia) (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Memorial Sloan-Kettering Cancer Center

Official(s) and/or principal investigator(s):
Susan Slovin, M.D, Principal Investigator, Affiliation: Memorial Sloan-Kettering Cancer Center


The purpose of this study is to see what effects the drug Rosiglitazone has on you and your prostate cancer. In particular, the study is also looking at the impact of the drug on Prostate Specific Antigen (PSA). PSA is a marker in your blood that is used to follow the progress of your disease.

Clinical Details

Official title: Rosiglitazone (Avandia) vs Placebo for Androgen-Dependent Prostate Cancer: A Randomized, Double-Blind, Placebo-Controlled Phase III Study

Study design: Interventional, Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Efficacy Study

Primary outcome: To compare the proportion of evaluable men who respond to rosiglitazone compared to the proportion of evaluable men who respond to placebo.

Secondary outcome: To compare time to progression between patients treated with rosiglitazone and those treated with placebo.

Detailed description: Rosiglitazone is a drug approved for the treatment of diabetes. It is similar to another drug that was given to prostate cancer patients. The PSA level went down in some of these patients. We do not know if this meant that the cancer was quiet and not getting worse or whether the drug would prevent the cancer from coming back. The drug in this study, rosiglitazone is more powerful in the way it stops cell growth and it has fewer side effects. We are studying this drug to see if it is more effective in treating prostate cancer that does not show up on scans and in keeping your PSA level from rising. The primary objective is to evaluate the activity of rosiglitazone by comparing changes in PSA doubling time (PSADT) between rosiglitazone-¬treated and placebo-treated men with androgen-dependent prostate cancer. The secondary objective will be to evaluate time to PSA progression as a secondary measure of the activity of rosiglitazone.
