Cryo-ablation Using DynaCAD / UroNAV

NCT04656678

Description:

The purpose of this research study is to determine the safety and feasibility of using the UroNav software and DynaCAD software for planning and treating prostate cancer as an add on to the already approved workflow of using ultrasound only during the cryoablation of the prostate. The software application may aid doctors in locating a prior biopsy proven cancer location from the UroNav biopsy that patients previously had and then use that information to guide the treatment.

Detailed Description

      This is a single-center, prospective, single arm study to evaluate feasibility of UroNAV
      Ablation system aided cryo-ablation treatment of low and intermediate risk, organ-confined
      prostate cancer. All subjects will be treated and then followed up clinically for up to 24
      months to evaluate any procedure or device related adverse events as well as to assess
      efficacy endpoints of the study. Additional data related to quality of life of treated
      subjects will also be collected

NameTypeDescriptionInterventions
DynaCAD / UroNAVExperimentalThis is a single arm study to evaluate feasibility of UroNAV Ablation system aided cryo-ablation treatment of low and intermediate risk, organ-confined prostate cancer. UroNav is a stereotaxic accessory for image-guided interventional and diagnostic procedures of the prostate gland. It provides 2D and 3D visualization of Ultrasound (US) images and the ability to fuse and register these images with those from other imaging modalities such as Magnetic Resonance (MR), Computed Tomography, etc. It also provides the ability to display a simulated image of a tracked insertion tool on a computer monitor screen that shows images of the target organ and the current and the projected future path of the interventional instrument. DynaCAD 5.0 is an image analysis and planning system that will provide off station, pre planning and review of interventional study data. It interfaces with the Uronav 4.0 fusion guidance system.

    Eligibility Criteria

            Inclusion Criteria:
    
              1. Patients must have documented histological or cytological evidence of tumor(s) of the
                 prostate.
    
              2. Patients must be ≥ 45 years of age.
    
              3. Patients must be able to read, understand and sign an informed consent.
    
              4. Organ confined clinical T1C or clinical T2a prostate cancer that is visualized on MR
                 imaging.
    
              5. Prostate cancer is diagnosed by MR image guided biopsies.
    
              6. Gleason Score ≤ 7; and 2 or less positive lesions on prior MR US fusion guided
                 prostate biopsy.
    
              7. A non MRI visible cancer detected via systematic standard biopsy will not be
                 considered an exclusion condition provided the non-MRI visible cancer is singularly
                 located in the contralateral hemisphere of the prostate; is Gleason 6 cancer; and

                 gland, they must be confirmed as likely to form a contiguous lesion with the target
                 lesion detected on MRI and therefore be from the same location in the prostate as MR
                 lesion was biopsied and proven to be cancerous. (e.g., Left/Right, Base, Mid Gland,
