NCT03514927

Brief Summary

This phase II trial studies how well high-intensity focused ultrasound works in treating participants with intermediate and high-risk prostate cancer. High-intensity focused ultrasound uses high frequency sound waves to deliver a strong beam which may target and destroy a specific part of the prostate, while minimizing damage to surrounding structures and tissue.

Outcome Measures

Primary Outcomes (1)

  • Mean percentage of viable clinically-significant prostate cancer (Gleason pattern 4 or 5) after high-intensity focused ultrasound (HIFU) treatment

    Determined by calculating the mean percent of viable cancer tissue remaining after HIFU using two different measurements: histologic examination of excised prostate specimen and histologic examination of post HIFU needle biopsy. Each of these two measurements will be investigated independently using two types of analyses as follows: percent viable cancer in excised prostate specimen and percent viable cells using post-HIFU needle biopsy. Will calculate the mean percent viable cancer across patients along with a corresponding 95% confidence interval based on all 32 fully evaluable patients.

    Up to 3 months

Secondary Outcomes (1)

  • Mean detection level of immunological factors

    Up to 3 months

Study Arms (1)

Treatment (HIFU, radical prostatectomy)

EXPERIMENTAL

HIFU PHASE: Participants undergo mpMRI and CEUS pre-HIFU treatment and then CEUS post-HIFU treatment. Participants then undergo HIFU treatment over 2-2.5 hours. PROSTATECTOMY PHASE: Within 2-4 weeks post-HIFU treatment, participants undergo mpMRI 1-2 days prior to radical prostatectomy. On the day of surgery, participants undergo CEUS prior to radical prostatectomy.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male having a diagnosis of clinically-significant prostate cancer (CsPCa) made within the past 12 months (Gleason 7-9) with no evidence of metastatic disease; all outside pathology will be re-reviewed at University of Southern California (USC) to verify diagnosis
  • Patients have elected to undergo radical prostatectomy (RP) as treatment of choice and have to be a surgical candidate for RP; this determination will be made by the patient in conjunction with their treating urologist and is current standard of practice
  • Standard preoperative evaluation is performed and deemed satisfactory to proceed to surgery as per their treating urologist
  • Ability to understand AND willingness to sign a written informed consent
  • Patients must be willing to undergo HIFU, CEUS, MRI and prostate biopsy pre-RP for research purposes

You may not qualify if:

  • Patients may not be receiving any other investigational agents or have received any definitive prostate cancer (PCa)-specific treatment (en-bloc resection of bladder tumors \[EBRT\], Brachytherapy etc) prior
  • Patients with known metastases would be excluded from this clinical trial
  • Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, clinical significant cardiac arrhythmia (rate controlled atrial fibrillation allowed), or psychiatric illness/social situations that would limit compliance with study requirements
  • Patients with active autoimmune diseases or active immune suppressive therapy or inflammatory bowel disease; a low dose steroid daily administration (equivalent dexamethasone \< 10mg/day) is acceptable
  • Patients with rectal disease
  • Patients who are unable to undergo MRI
  • Patients with convincing evidence of extraprostatic extension or T4 disease on digital rectal examination (DRE)
