简要总结

This clinical trial tests whether the magnetic resonance imaging (MRI)-guided transurethral ultrasound ablation (TULSA) procedure is safe and effective in treating patients with low to intermediate grade prostate cancer. MRI-guided TULSA ablation is a minimally invasive procedure that uses an ultrasound device guided by MRI imaging to deliver high-energy sound waves, producing very high temperature to ablate (destroy) tumor cells in a targeted manner. The MRI-guided TULSA procedure may help patients avoid surgery and help improve prostate cancer patients' quality of life.

详细描述

PRIMARY OBJECTIVE:

I. To perform the TULSA procedure for safety and efficacy outcomes in men aged 45 to 80 years with biopsy-confirmed, National Comprehensive Cancer Network (NCCN) low to intermediate-risk prostate cancer.

SECONDARY OBJECTIVE:

I. To assess patient-reported metrics for quality of life (QOL). II. To assess return to normal activity. III. Compare economic benefit as noted from Expanded Prostate Cancer Index Composite (EPIC) questionnaire.

入选标准

  • Age 45-80 years, with > 10 years life expectancy
  • Biopsy-confirmed, NCCN [Gleason Grade (GG) 1, favorable GG 2 and unfavorable GG3] intermediate-risk prostate cancer
  • Stage =< T2c, N0, M0
  • International Society of Urological Pathology (ISUP) grade group 1, 2, or 3 disease on transrectal ultrasonography (TRUS)-guided biopsy (minimum 8 cores, combination of systematic and MRI fusion-guided) or in-bore biopsy [minimum 3 cores from each Prostate Imaging-Reporting and Data System (PI-RADS) version (v)2 category >= 3 lesion]. Biopsy reported within 12 months of baseline visit, with minimum 6-week interval between biopsy and baseline
  • Prostate specific antigen (PSA) =< 20 ng/mL reported within 3 months of baseline
  • Treatment naive
  • Planned ablation volume < 3.0 cm axial radius from the urethra on mpMRI acquired within 6 months of baseline

排除标准

  • Inability to undergo MRI or general anaesthesia
  • Suspected tumour > 30 mm from the prostatic urethra or < 14 mm from the prostatic urethra
  • Prostate calcifications > 3 mm in maximum extent obstructing ablation of tumor on low-dose pelvic computed tomography (CT)
  • Criteria subject to additional review and approval by sponsor. Alternatively, prospective TRUS to query calcifications or susceptibility-weighted MRI if available may be used to assess calcification. Imaging for calcification screening must be dated within 1 year of baseline visit
  • Unresolved urinary tract infection or prostatitis
  • History of proctitis, bladder stones, hematuria, history of acute urinary retention, severe neurogenic bladder
  • Artificial urinary sphincter, penile implant or intraprostatic implant
  • Less than 10 years life expectancy
  • Patients who are otherwise not deemed candidates for radical prostatectomy (RP)
  • Inability or unwillingness to provide informed consent
  • History of anal or rectal fibrosis or stenosis, or urethral stenosis, or other abnormality challenging insertion of devices

结局指标

主要结局

Proportion of patients free from treatment failure

时间窗: At 24 months post-treatment

Failure is defined as: delivery of any additional intervention for prostate cancer (local or systemic, including adjuvant therapy); or metastatic disease; or prostate cancer-specific death.

Proportion of patients who maintain both urinary continence and erectile potency

时间窗: At 12 months

Continence is defined as 'pad-free' (0 pads/day), and potency is defined as erection firmness sufficient for penetration (Expanded Prostate Cancer Index Composite \[EPIC\]). Two-sided, 95% Pearson-Clopper confidence interval (CI) will be calculated for each intervention arm separately, and the difference in safety outcomes, along with exact 95% two-sided CI will be calculated.

次要结局

  • Biochemical failure(Up to 24 months)
  • Histologic failure(At 12 months)
  • Multiparametric magnetic resonance imaging (mpMRI) Prostate Imaging and Reporting and Data System (PI-RADS) version 2 score for each visible lesion(At 24 months post-treatment)
  • Total prostate volume(At 24 months post-treatment)
  • Salvage-free survival(Up to 24 months)
  • Biochemical failure-free survival(Up to 24 months)
  • Histologic failure-free survival(Up to 24 months)
  • Metastasis-free survival(Up to 24 months)
  • Change in quality of life(Baseline up to 24 months)
  • Prostate cancer-specific survival(Up to 24 months)
  • Overall survival(Up to 24 months)
  • Change in patient-reported genitourinary function(Baseline up to 24 months)
