Brief summary

This study will be designed to define the efficacy and safety of ablative therapies in the management of localized prostate cancer and comprehensively evaluate quality of life outcomes and oncologic control following treatment.

Detailed description

This study will be designed to define the efficacy and safety of ablative therapies in the management of localized prostate cancer and comprehensively evaluate quality of life outcomes and oncologic control following treatment. There are several commercially available standard of care treatments available for local therapy of the prostate. Ablative therapies may be delivered via a whole gland or focal approach by systems including cryoablation (CA), brachytherapy, irreversible electroporation (IRE), high intensity focused ultrasound (HIFU), MRI-guided transurethral ultrasound ablation (TULSA) procedure or future novel prostate ablation systems. These are single, outpatient treatments lasting between 2-4 hours and include treatment planning and energy delivery under guidance and are either administered via transperineally approach (cryoablation, IRE, brachytherapy) or via the urethral (TULSA-Pro) or rectum (HIFU). This study protocol will not include experimental therapy and the enrolled subjects will undergo the ablative therapy as part of their standard of care treatment.

Primary

MeasureTime frameDescription
Oncologic outcomes as assessed by the rate of negative in-field biopsy at 12 months (primary setting)12 months post treatmentOncologic outcomes will be assessed by the rate of negative in-field biopsy at 12 months which is defined by the Delphi consensus criterion of absence of clinically significant disease (≤ 3 mm of Gleason ≤ 6 disease in any biopsy core is insignificant)
Oncologic outcomes as assessed by the rate of advancement to systemic therapy or radical salvage therapies (primary setting)3 years post treatmentOncologic outcomes will be assessed by the rate of advancement to systemic therapy or radical salvage therapies which is defined by prostatectomy, radiation or hormone therapy.
Oncologic outcomes as assessed by the rate of negative in-field biopsy at 12 months (salvage setting)12 months post treatmentOncologic outcomes will be assessed by the rate of negative in-field biopsy at 12 months which is defined by the Delphi consensus criterion of absence of clinically significant disease (≤ 3 mm of Gleason ≤ 6 disease in any biopsy core is insignificant)
Oncologic outcomes as assessed by the rate of progression to systemic therapy or radical salvage therapies (salvage setting)3 years post treatmentOncologic outcomes will be assessed by the rate of progression to systemic therapy or radical salvage therapies which is defined by prostatectomy, radiation or hormone therapy.
Change in urinary function as measured by International Prostate Symptom Score (IPSS) questionnaire (primary setting)Baseline and 12 months post treatmentChange in urinary function is measured by International Prostate Symptom Score (IPSS) questionnaire which measures urinary symptoms and continence and the scores range from 0 to 35. A change \> 3 points between baseline and follow-up assessments is defined as meaningful for the IPSS. Therefore, increases in IPSS scores larger than 3 points will be categorized as reduced urinary function (worse outcome).
Change in urinary function as measured by International Prostate Symptom Score (IPSS) questionnaire (salvage setting)Baseline and 12 months post treatmentChange in urinary function is measured by International Prostate Symptom Score (IPSS) questionnaire which measures urinary symptoms and continence and the scores range from 0 to 35. A change \> 3 points between baseline and follow-up assessments is defined as meaningful for the IPSS. Therefore, increases in IPSS scores larger than 3 points will be categorized as reduced urinary function (worse outcome).
Change in erectile function as measured by International Index of Erectile Function (IIEF-5) score questionnaire (primary setting)Baseline and 12 months post treatmentChange in erectile function is measured by International Index of Erectile Function (IIEF-5) score questionnaire which classifies patients into five severity levels ranging from none (22-25 points) to severe (5-7 points). Patients whose IIEF-5 levels worsen from baseline to follow-up will be categorized as having reduced erectile function.
Change in erectile function as measured by International Index of Erectile Function (IIEF-5) score questionnaire (salvage setting)Baseline and 12 months post treatmentChange in erectile function is measured by International Index of Erectile Function (IIEF-5) score questionnaire which classifies patients into five severity levels ranging from none (22-25 points) to severe (5-7 points). Patients whose IIEF-5 levels worsen from baseline to follow-up will be categorized as having reduced erectile function.

Secondary

MeasureTime frameDescription
Number of participants with adverse events or short-term complications (primary setting)30 days post treatmentAdverse events (AE)s will be monitored and evaluated by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 for 30 days post-treatment
Number of participants undergoing combined treatment of the transitional zone (TZ ) due to bladder outlet obstruction caused by Benign prostatic hyperplasia (BPH)Baseline and 12 months post treatmentNumber of participants undergoing combined treatment of the transitional zone (TZ ) due to bladder outlet obstruction caused by BPH will be evaluated to determine efficacy of treatment of the transitional zone in patients with lower urinary tract symptoms (LUTS) due to BPH via International Prostate Symptom Score (IPSS) questionnaire
Number of participants with adverse events or short-term complications (salvage setting)30 days post treatmentAdverse events (AE)s will be monitored and evaluated by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 for 30 days post-treatment
Number of participants with adverse events or long-term complications (primary setting)3 years post-treatmentAn adverse event (AE) will be monitored and evaluated by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 for up to 3 years post-treatment
Number of participants with adverse events or long-term complications (salvage setting)3 years post-treatmentAn adverse event (AE) will be monitored and evaluated by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 for up to 3 years post-treatment
