结局指标

主要结局

Proportion of Participants with Disease Progression Within 12 Months After Initiating TRT

时间窗: 12 months

Disease progression is defined as either (1) an increase in prostate cancer grade group on biopsy or (2) conversion from active surveillance to active treatment (e.g., surgery, radiation, or systemic therapy). The proportion of participants who meet either criterion within 12 months of initiating testosterone replacement therapy (TRT) will be reported.

次要结局

  • Progression-Free Survival (PFS) from Baseline to 5 Years(Baseline to 5 Years)
  • Mean Change in Serum PSA Levels (ng/mL) from Baseline to 12 Months(Baseline, 12 Months)
  • Change in Total Testosterone Levels (ng/dL) from Baseline to 12 Months(Baseline, 12 Months)
  • Mean Change in Hematocrit Levels (%) from Baseline to 12 Months(Baseline, 12 Months)
  • Mean Change in Prostate Volume (mL) as measured by mpMRI from Baseline to 12 Months(Baseline, 12 Months)
  • Mean Change in EPIC-26 Scores from Baseline to 12 Months(Baseline, 12 Months)
  • Mean Change in SF-12 Scores from Baseline to 12 Months(Baseline, 12 Months)
  • Mean Change in Aging Male's Symptoms Score (AMS) from Baseline to 12 Months(Baseline, 12 Months)
