  • THERAPY NAIVE FAVORABLE RISK PROSTATE CANCER COHORT (COHORT 2) ONLY: No prior therapy for prostate cancer defined as:
  • Local therapy including surgery , radiation or focal therapy (cryoablation, HIFU, light)
  • Systemic therapy (hormonal, immunotherapy, targeted, chemotherapy). Subjects who have used 5-alpha reductase inhibitor (e.g. finasteride or dutasteride) \> 6 months prior to D1 of protocol therapy will be allowed
  • Platelets \> 100,000 /mm\^3 (within 28 days prior to day 1 of protocol therapy)
  • Hemoglobin \> 8 g/dL (within 28 days prior to day 1 of protocol therapy)
