Study of NanoKnife for Ablation of Prostate Cancer in Intermediate Risk Patients

This study will involve six (6) subjects who meet the intermediate risk prostate cancer criteria defined by this protocol. The biopsy and imaging techniques that we will adopt within this trial are multiparametric MRI (mpMRI) and transperineal prostate biopsy (template mapping and/or limited targeted). The subjects' prostate cancer foci, the location of which will be determined by ultrasound guided transperineal prostate biopsy, will be targeted for treatment with the NanoKnife System. The primary objective of this the study will be to evaluate procedural and short-term post treatment safety of the NanoKnife treatment via incidence of adverse events and evaluation of effect on urologic (urinary and erectile) function. The secondary objective of this study is to evaluate the short term efficacy of the NanoKnife treatment. Local efficacy in the area of treatment will be assessed by histological evaluation of transperineal prostate biopsy cores at six (6) months post NanoKnife treatment, to evaluate the ablation zone created by the NanoKnife treatment. Other secondary outcomes include health-related quality of life levels evaluated using validated patient questionnaires. Following the 6 month transperineal prostate biopsy and mpMRI assessment, the data from these 6 subjects will be submitted to FDA for confirmation of short term safety and efficacy.
