Study of Metformin With Simvastatin for Men With Prostate Carcinoma

The purpose of this study is to find out whether the two drugs used in the study, metformin and simvastatin, can slow down the speed of rise of prostate specific antigen (PSA) or stop its rise or even bring the level down. Recently, scientists noticed that men who take metformin to treat their high blood sugar or simvastatin to treat their high cholesterol are less likely to develop prostate cancer. Also, scientists found that, when these drugs are used in preclinical studies, they can slow down the growth of the prostate cancer cells. This study will try to find out whether these drugs can actually slow down the growth of prostate cancer in men.
