Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Proportion of men who are free of any prostate cancer (PC) in the treated area AND are free of clinically significant PC in the untreated area 36 months after focal therapy comprising HIFU
  • Proportion of men who are free of clinically significant PC in the treated and untreated area 36 months after HIFU

Secondary Outcome Measures:
  • The presence of severe erectile dysfunction (ED) at 12 and 36 months, as measured by the International Index of Erectile Function (IIEF-15) questionnaire with or without the use of phosphodiesterase-5 inhibitors, in those with absence of severe ED at ...
  • The presence of any new/progression of ED at 12 and 36 months, measured as an at least 6-point drop in IIEF-15 questionnaire score within the erectile function (EF) domain
  • Time to return of EF (absence of severe ED on IIEF-15 questionnaire)
  • Need for phosphodiesterase-5 inhibitors to maintain EF sufficient for penetration at 36 months
  • The presence of ejaculatory function at 12 and 36 months as measured by the orgasmic function domain of the IIEF-15 questionnaire
  • The presence of orgasmic function at 12 and 36 months as measured by the orgasmic function domain of the IIEF-15 questionnaire
  • Presence of a significant decrease in penile length at 36 months as measured by pre-and post-treatment stretch-flaccid penile length (patients at UCLH/ UCL trial center only)
  • Presence of pain during intercourse requiring premature cessation of intercourse (i.e., prior to climax), at 36 months
  • Presence of urinary incontinence (UI; any pad usage plus any leakage of urine) as determined by the UCLA-EPIC urinary continence questionnaire, at 12 months and 36 months, in those men with no UI at baseline
  • Presence of UI as determined by the UCLA-EPIC urinary continence questionnaire at 12 months and 36 months
  • Time to return of urinary continence (as determined by UCLA-EPIC Urinary domain questionnaire)
  • Grading of lower urinary tract symptoms as determined by IPSS scores at 12 months and 36 months
  • Presence of bowel toxicity as determined by the UCLA-EPIC Bowel questionnaire at 12 months and 36 months
  • Anxiety levels as measured by the Memorial Anxiety Scale for Prostate Cancer
  • General health-related quality of life as measured using EQ-5D and the RAND 36 item Health Survey125
  • Absence of any PC on transrectal ultrasound (TRUS) biopsy in the treated area at 12 months
  • Histology of men with absence of clinically significant (CS) PC in the treated area at 36 months in patients who had CS-PC in the treated area
  • Absence of any PC in the untreated area at 36 months by transperineal template prostate mapping (TTPM) histology in patients who had no PC at baseline TTPM in the untreated area
  • Absence of CS-PC in the untreated area at 36 months by TTPM histology in patients who were free of CS-PC at baseline
  • Biochemical (PSA) kinetics and the optimal biochemical definition of failure
  • Composite end-point on cancer control as defined by time to failure defined on histological OR biochemical OR clinical parameters
  • Achievement of trifecta status (i.e., no severe ED, pad-free leak-free continence, cancer control with absence of CS-PC) at 36 months in men with good baseline function
  • Time to initiation of secondary PC intervention (prostatectomy, radiotherapy, androgen ablation, whole-gland HIFU, or cryosurgery) as a result of histological burden ≥ Gleason pattern 3 and/or max CCLI ≤ 3 mm or rising PSA or for any cause
  • Evaluation of risk factors predictive of failure as defined by presence of any cancer or presence of CS-PC at study end
  • Development of healthcare economic model to evaluate the cost-effectiveness by comparison of GU and cancer control outcomes against matched groups from existing studies evaluating standard care (active surveillance and radical therapies)
  • The clinical validity (sensitivity, specificity, negative and positive predictive values, inter-observer variability) of MRI changes to predict presence of residual/recurrent CS-PC on biopsy
  • The clinical validity of multi-parametric MRI or HistoScanning™ to predict presence of CS-PC on template transperineal prostate-mapping biopsies prior to focal therapy
  • The clinical validity of HistoScanning™ to predict presence of residual/recurrent CS-PC on biopsy

    • Template biopsy with the any of the following:

      • Unilateral disease with any burden
      • Bilateral disease with 1 of the following:

        • Presence of clinically significant cancer on only one side (as determined by histological rules described above) and Gleason ≤ 7
        • Clinically insignificant disease with a burden of > 50% of biopsy cores taken on that side
        • Bilateral clinically insignificant disease and < 50% of biopsy cores positive on any one side but with dominant disease burden on one side
  • Low- to intermediate-risk disease, meeting all of the following criteria:

    • PSA < 15 ng/mL
