Launched in January 1994, the PCPT was a large randomized clinical trial designed to test whether the drug finasteride could help prevent prostate cancer in men age 55 and older.
Finasteride blocks the activity of 5-alpha reductase, an enzyme that helps control the activity of the hormone testosterone. Since there was no concentration-dependent effect on prostate cancer, any exposure to finasteride intake may reduce prostate cancer risk.
