Primary outcomePrimary: Measurable Silibinin Tissue Levels — 3 Participants
Summary
Silibinin has demonstrated anti-cancer activity in the laboratory for several different cancer types, including prostate cancer. Silibinin was originally obtained from milk thistle. Silybin-Phytosome, an oral form of silibinin, has been tested previously in prostate cancer patients to determine the safety of high-dose treatment. This study is for men with prostate cancer who are planning to have their prostate surgically removed. Participants will be given Silybin-Phytosome three times a day from enrollment in the study until the time of their surgery. Participation in this study will not affect the timing of surgery. We obtain blood and urine samples at the start and completion of the trial in addition to prostate tissue from the surgery. These samples will be analyzed for the effect of Silybin-Phytosome at the end of the study.
