Brief summary
In this study the investigators will find out whether the use of a new type of boost approach called irreversible electroporation (IRE) is as effective as the standard boost approach of radiation therapy for participants with intermediate-risk prostate cancer receiving standard stereotactic body radiotherapy (SBRT).
Interventions
The NanoKnife System is the device that is used for Irreversible Electroporation/IRE. The NanoKnife Generator is a microprocessor-controlled low energy direct current (LEDC) irreversible electroporation device.
Radiation-based treatment intensification involves delivery of a boost to the dominant intraprostatic lesion (DIL) to a higher dose than the surrounding prostate tissue using external beam radiation therapy.

Eligibility
Inclusion criteria
* Biopsy proven grade group 2 or 3 (GS 3+4 or GS 4+3) cancer with all pattern 4 found only in the MRI target; systematic biopsy pattern 4 that is concordant with MRI target per investigator is permissible * Gland size ≤ 80 cc * Prostate MRI \< rT3b disease * IPSS \< 20 * No contraindication to IRE, RT, anesthesia, or transperineal procedure
Exclusion criteria
* Any Grade Group ≥4 disease, or any cribriform and/or intraductal carcinoma * Evidence of nodal or /metastatic disease on MRI and/or PSMA PET/CT * Unfit for general anesthesia, or contraindication/hypersensitivity to required neuromuscular blocking agents * Active urinary tract infection (UTI) at the time of IRE or biopsy; must be treated and resolved prior to proceeding * Actively bleeding, known bleeding disorder, or inability to interrupt anticoagulants/antiplatelet therapy as clinically indicated for biopsy/IRE safety * Any history of cardiac arrhythmia or epilepsy, or recent myocardial infarction, consistent with NanoKnife contraindication statements * Presence of an implanted pacemaker/defibrillator or other active implanted electronic device, or other device-related contraindications per current NanoKnife labeling/user manual * Inability to undergo pelvic MRI * Prior treatment of prostate cancer including androgen deprivation therapy, focal therapy, radiation therapy, or prostatectomy * Current or intended use of androgen deprivation therapy
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Biopsy negative rate at 2 years | 2 years | The primary objective is to demonstrate that Irreversible Electroporation/IRE boost is non-inferior with respect to negative biopsy rate at 2 years compared to Radiation Therapy/RT boost. This is measured by the two-year biopsy negative rate for the control group and the intervention group. |
