Detailed Description

This is a pilot, randomized, window-of-opportunity treatment trial in which participants with previously untreated prostate cancer who are candidates for surgery (radical prostatectomy) will receive one cycle of therapy consisting of Glycyrrhizin (GLY) (Observation, Dose Level 1 75mg daily, or Dose Level 2, 150mg daily) for 6 weeks (+/- 2 weeks) prior to surgery.
