February 4, 2019 updated by: NYU Langone Health

Unilateral Nerve-Sparing Cryoablation for Low-Risk, Clinically Localized, Unilateral Prostate Cancer in Potent Men: A Prospective, Phase II Trial

Men with low-risk, clinically localized, unilateral prostate cancer will be treated with unilateral nerve-sparing cryoablation and evaluated for the rate of potency, cancer control and health related quality of life outcomes after treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a clinical trial to determine and assess the change in the rate of potency in men with low-risk, localized, unilateral prostate cancer who have not received previous treatment. A total of 86 men between 40 to 69 years of age with biopsy proven, early stage localized prostate cancer will receive unilateral nerve-sparing cryoablation. The study includes a screening/pre-operative visit, a cryoablation procedure day, and 10 follow up visits over the course of 36 months. The first follow-up visit will occur within 2 weeks (±1 week) after cryoablation. Thereafter, follow-up visits will be scheduled, from the date of procedure, every 3 months (±3 weeks) for 18 months and every 6 months (±3 weeks) thereafter until the patient completes the protocol, 36 months after the cryoablation procedure.

Phase

Phase

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

36 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Exclusion Criteria:

  • Active urinary tract infection
  • Evidence of metastatic disease
  • Irreversible bleeding diathesis or other bleeding disorders
  • Anatomic penile abnormalities precluding cryoablation

  • Current or history within the past 6 months of alcohol and/or substance abuse which would impair participation in the study
  • Major medical disorder (i.e. uncontrolled diabetes, significant hepatic, renal, or hematological disorders, recent stroke or myocardial infarction), in the opinion of the urologist, is an illness or complication which is not consistent with the protocol requirements
  • Unwilling to undergo the necessary follow-up for the trial period
  • Bilateral prostate cancer disease
  • Significant median lobe of the prostate which would preclude an adequate cryoablation procedure (based on the discretion of the urologist)
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrythmia, or psychiatric illness/social situations which would limit compliance with study requirements
