Brief Summary:
Stage 2B: NanoTherm ablation of focal prostate cancer in small lesions in Gleason 3+4 disease. The outcome of this ablation is validated by a transperineal biopsy at 4 months after ablation.

Prostate Cancer Device: NanoTherm Ablation Not Applicable

Detailed Description:

Presently, patients having intermediate-risk prostate carcinoma have to make a very difficult decision regarding treatment, as active surveillance will not immediately alter the current quality of life. However, because there is a risk of progressive disease or due to patient anxiety due to an untreated tumor, many patients opt for active treatment, often using radiation or prostatectomy, and sometimes in combination with androgen deprivation. Unfortunately, radiation, surgery, and androgen deprivation have multiple and potentially profound side effects including sexual, urinary, and bowel complications. As a small fraction of men dies from this disease, the number of men needed to treat to prevent one death is large, resulting in many men with side effects or complications to help prevent the one death. It is for these reasons that there is a major need for focal therapy for this group of patients who most commonly are treated actively with surgery or radiation; such focal therapy could ablate the detected tumor(s) within the prostate, control the disease while avoiding side effects of whole gland therapies and controlling tumor growth within the prostate detected by (multiparameter-) MRI and histopathologically confirmed by biopsy. MagForce NanoTherm® Therapy offers this option by noninvasive ablation of small tumors in a 1-2 ml target volume of the prostate, a treatment that is not possible with any other technology on the market.

This study evaluates the use of NanoTherm ablation as a method of treating these intermediate grade lesions allowing patients to return to active surveillance without definitive treatment such as external beam radiation or prostatectomy.

Arms and Interventions

Arm Intervention/treatment
Experimental: Ablation Arm
Subjects in this arm of the study will have focal ablation of the prostate cancer lesion with the NanoTherm technology. This ablation will be followed-up transperineal prostate biopsy at 4 months after treatment.
 Device: NanoTherm Ablation
Iron nanoparticles are instilled into the prostate cancer lesion and then the particles are heated using a magnetic field and this heating ablates the prostate cancer lesion.

Criteria

Inclusion Criteria:

  • Age 40 to 85
  • Male
  • Prostate adenocarcinoma on biopsy
  • Clinical stage T1c/T2a/T2b, N0, M0/Mx with no lesion larger than 2cc in volume

  • The following biopsy findings (biopsy must have MRI visualization and be within 6 months of planned NanoTherm® treatment):

    • A positive biopsy for prostate cancer from the MRI-visualized lesion, at least one of which must be Gleason 3+4 (grade group 2)
  • Lesion must be visualized by Multiparametric Magnetic Resonance Imaging (MP-MRI) on a scan that is less than 6 months old
  • Patient expresses a preference for active surveillance, rather than surgery or radiation, to manage prostate cancer
  • Based on the evaluation of the study investigator, appropriate for instillation of NanoTherm® under anesthesia based on location and size of the clinical target volume (CTV)

Exclusion Criteria:

  • Metallic implants below the neck
  • Gleason 3+4 or higher cancer on prostate biopsy outside of the planned CTV
  • Gleason 4+3 or higher on any prostate biopsy
  • Hematological abnormality indicating increased risk of bleeding or clotting, for example low platelet count or anemia
  • Participation concurrently in another clinical trial for prostate disease or in the last 30 days
  • Known hypersensitivity to Axumin®
