NCT02967458

Brief Summary

This is a phase II single center study using contrast-enhanced ultrasound to identify aggressive forms of prostate cancer with subharmonic imaging. The following are the study objectives:

  1. 1.To implement subharmonic imaging technology on a transrectal probe suitable for prostate imaging and biopsy
  2. 2.To demonstrate visualization of prostatic vascularity using subharmonic contrast-enhanced imaging.
  3. 3.To provide a preliminary estimate of the diagnostic accuracy of contrast-enhanced subharmonic imaging for detection of clinically significant PCa.

Outcome Measures

Primary Outcomes (3)

  • Percentage of Subjects Whose Prostate Cancer Was Detected With Subharmonic Imaging

    The initial phase of the trial will develop and test subharmonic imaging to demonstrate enhanced visualization of prostate vascularity in all study participants. We will report the percentage of study subjects in whom visualization of prostate vascularity is increased with subharmonic imaging.

    One week from baseline

  • Percentage of Biopsy Cores in Which Prostate Cancer Was Detected Using Subharmonic Imaging

    Study subjects will be scanned with subharmonic imaging during infusion of the microbubble contrast agent. Imaging results will be compared to pathology on prostate biopsy.

    One week from baseline

  • Percentage of Subjects With Previously Unidentified Prostate Cancer Using Magnetic Resonance Imaging

    Study subjects will be scanned with subharmonic imaging during infusion of the microbubble contrast agent. Imaging results will be compared to pathology on prostate biopsy.

    One week from baseline

Study Arms (1)

Prostate Biopsy Patients

EXPERIMENTAL

Fifty patients who are scheduled for a clinically indicated prostate biopsy, and who are able to undergo contrast enhanced transrectal ultrasound will be included in this single arm study. Each of the study subjects will receive in intravenous infusion of a microbubble contrast agent known as Definity™, (Perflutren Lipid Microsphere, Lantheus Medical Imaging, Inc; N. Billerica, MA). Based upon our previous experience, two vials of Perflutren Lipid Microsphere will be mixed and diluted in 50 ml of normal saline, yielding a concentration of 49.4 μl/ml. For the purpose of contrast-enhanced imaging, Perflutren Lipid Microsphere will be infused over approximately 10-12 minutes, during which time ultrasound imaging and biopsy will be performed.

Drug: Perflutren Lipid Microsphere Intravenous Suspension

Interventions

The intravenous administration of Perflutren Lipid Microsphere will provide enhancement of vascular tissue when performing subharmonic prostate ultrasound imaging. This enhancement will be used to guide targeted biopsy of the prostate to vascular areas which are more likely to contain aggressive prostate cancer.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject must be scheduled for a clinically indicated needle biopsy of the prostate based upon an elevated PSA, abnormal digital rectal examination, or based upon active surveillance of prostate cancer.
  • Subject must be able and willing to give written informed consent for a contrast enhanced ultrasound study of the prostate.
  • Subject must be a male at least 18 years of age when informed consent is obtained.
  • Subject must have a life expectancy that exceeds the duration of the clinical trial.

You may not qualify if:

  • Participant in a clinical trial involving an investigational drug within the past 30 days.
  • Prior allergic reaction to the ultrasound contrast agent Definity™
  • Previous treatment for PCa.
  • Clinically unstable, severely ill, or moribund.
