What is the purpose of this trial?

This trial tests a new method to treat prostate cancer using advanced imaging software to guide cryo-ablation, which involves freezing cancer cells to destroy them. The goal is to determine if these software tools can safely and effectively help doctors target cancerous areas more precisely. Men with prostate cancer confirmed by MRI-guided biopsy, which has not spread beyond the prostate, are ideal candidates.

As an unphased trial, this study offers patients the opportunity to contribute to innovative research that could enhance the precision of prostate cancer treatment.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but it does exclude patients who have been on medications affecting PSA levels in the last 3 months. It's best to discuss your specific medications with the trial team.

What prior data suggests that the UroNav and DynaCAD software is safe for use in cryo-ablation of prostate cancer?

Research has shown that cryo-ablation, guided by advanced imaging systems like UroNav, is generally safe for treating prostate cancer. Studies have found that this method effectively targets cancer while preserving important functions.

A review of various studies found that cryo-ablation for prostate cancer yielded good results with few side effects. Patients reported satisfaction with the treatment and maintained important functions like sexual potency. Another study noted that imaging guidance makes cryo-ablation a safe option, especially for those at intermediate risk.

Overall, using DynaCAD and UroNav to plan and guide cryo-ablation is well-tolerated, typically not causing severe side effects. This makes it a promising choice for patients considering this treatment. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Cryo-ablation using the DynaCAD and UroNAV systems is unique because it combines advanced imaging and precision technology to treat prostate cancer. Unlike traditional treatments like surgery or radiation, which can be more invasive or have broader systemic effects, this method uses cryo-ablation to target and freeze cancer cells directly. The DynaCAD and UroNAV systems enhance this process by providing detailed 2D and 3D images, allowing for precise navigation and planning. Researchers are excited because this approach may offer a less invasive treatment option with potentially fewer side effects, while still effectively targeting cancer cells.

What evidence suggests that the UroNav and DynaCAD software is effective for treating prostate cancer?

Research has shown that cryo-ablation effectively treats early-stage prostate cancer. It can be repeated if necessary and typically allows for quicker recovery. In this trial, doctors perform cryo-ablation using imaging tools like DynaCAD and UroNav to target cancer cells more accurately. These tools assist in visualizing and planning the procedure, enhancing precision. This method is known to yield good results for managing prostate cancer in its early stages. ^{1 2 3 5 6}

What Are the Treatments Tested in This Trial?

Interventions

• Cryo-ablation Using DynaCAD / UroNAV preplanning / guidance

Trial Overview The trial is testing the safety and effectiveness of using UroNav software combined with DynaCAD for planning cryo-ablation treatments in prostate cancer patients. This technology aims to improve upon ultrasound-only methods by better locating tumors identified in previous biopsies for targeted treatment.

How Is the Trial Designed?

Group I: DynaCAD / UroNAV Experimental Treatment 1 Intervention

This 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.

Cryo-ablation Using DynaCAD / UroNAV preplanning / guidance is already approved in United States, European Union, Canada for the following indications:

Approved in United States as Cryoablation for:

• Prostate cancer

Approved in European Union as Cryoablation for:

• Prostate cancer
• Kidney cancer
• Liver cancer

Approved in Canada as Cryoablation for:

• Prostate cancer
• Kidney cancer

Published Research Related to This Trial

Percutaneous transperineal cryoablation is an emerging treatment for prostate cancer, utilizing advanced imaging and cryosurgical technology to improve patient outcomes.

This technique is suitable for various patients, particularly for primary treatment of localized prostate cancer, as salvage therapy after other treatments fail, and for alleviating local symptoms.

Cryoablation for carcinoma of the prostate. Patel, BG., Parsons, CL., Bidair, M., et al.[2016]

Transrectal ultrasound-guided percutaneous transperineal prostate cryoablation is a minimally invasive outpatient procedure that effectively treats localized prostate cancer, showing promising results with an 81% success rate in controlling the disease and minimal morbidity over a follow-up period of 5 years.

While cryoablation is effective, especially for low-volume cancers, the complication rates, particularly for salvage procedures after radiation therapy, can be higher, indicating the need for careful patient selection and consideration of treatment history.

In a study of 15 patients with locally recurrent prostate cancer after radical retropubic prostatectomy, 40% experienced sustained declines in PSA levels following interstitial transperineal cryoablation, indicating potential effectiveness of this treatment.

The success of cryoablation was associated with lower pre-treatment Gleason scores and smaller lesion sizes, suggesting that patients with more favorable cancer characteristics may benefit more from this approach.
