intraepithelial neoplasia (PIN).
The purpose of this study is to determine if toremifene citrate is effective and safe in the
prevention of prostate cancer in men who have been diagnosed with high grade prostatic
intraepithelial neoplasia. Men who have ever been diagnosed with high grade PIN will be
enrolled into an 36 month trial and will be assigned to either 20 mg of study drug or placebo
per day. Subjects will undergo safety evaluations at Month 3, Month 6, Month 12, Month 18,
Month 24, Month 30 and Month 36 along with prostate biopsies at Month 12 and Month 24 and
Month 36 to determine efficacy.
