About this study

Official title: Erectile Dysfunction Recovery in Men Age </=65 Treated With Bilateral Nerve Sparing Robotic Assisted Prostatectomy (BNS-RAP) for Prostate Cancer

RATIONALE: Sildenafil citrate and alprostadil may help patients who have undergone prostatectomy for prostate cancer to recover from erectile dysfunction.

PURPOSE: This randomized clinical trial is studying giving sildenafil together with alprostadil in treating patients undergoing nerve-sparing robotic-assisted radical prostatectomy for nonmetastatic prostate cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the rate of erectile function (defined as the ability to achieve and maintain an erection sufficient for intercourse without the use of pharmacological assistance) at 1 year post-operatively in men undergoing BNS-RAP without the use of post-operative maintenance pharmacotherapy.

II. To describe whether early post-operative maintenance pharmacotherapy Viagra can improve return of erectile function at 1 year post-operatively in patients undergoing BNS-RAP.

III. To describe if early post-operative maintenance pharmacotherapy Viagra can decrease the time-to-return of erectile function in patients undergoing BNS-RAP.

SECONDARY OBJECTIVES:

  1. To describe whether early post-operative maintenance pharmacotherapy MUSE can improve return of erectile function at 1 year post-operatively in patients undergoing BNS-RAP.

II. To describe if early post-operative maintenance pharmacotherapy MUSE can decrease the time-to-return of erectile function in patients undergoing BNS-RAP.

III. To compare sexual function quality of life in men undergoing early post-operative maintenance pharmacotherapy to those without early post-operative maintenance pharmacotherapy.

IV. To compare the rate of potency at 1, 3, 6, 9, 12, and 18 months in men using Viagra versus MUSE for early post-operative maintenance pharmacotherapy.

  1. To describe the dropout rate for MUSE maintenance pharmacotherapy secondary to urethral pain in men using 2% Lidocaine lubricant.

VI. To describe if penile length is decreased following BNS-RAP. VII. To describe if penile length at one year is different in men who have return of potency versus those with no return of potency.

OUTLINE: Patients receive 2 doses of intraurethral alprostadil prior to undergoing bilateral nerve-sparing robotic-assisted prostatectomy. Within 4 weeks after surgery, patients are randomized to 1 of 3 treatment arms.

ARM I: Patients receive intraurethral alprostadil once daily for up to 9 months in the absence of disease progression or unacceptable toxicity. Patients also receive 3 doses of oral sildenafil citrate at least 48 hours apart monthly for up to 18 months.

ARM II: Patients receive 3 doses of oral sildenafil citrate on 3 separate occasions at least 48 hours apart monthly for 18 months.

ARM III: Patients receive oral sildenafil citrate once daily for up to 9 months in the absence of disease progression or unacceptable toxicity. Patients also receive 3 doses of oral sildenafil citrate at least 48 hours apart monthly for up to 18 months.

After completion of study treatment, patients are followed periodically for up to 18 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Potency Rates (Ability to Obtain an Erection Sufficient for Penetration) Without Assistance Compared Between Patients in All Three Arms of the Study at 12 Months

    Potency rates (ability to obtain an erection sufficient for penetration) without assistance in those patients receiving maintenance Viagra compared to non-pharmacology controls was compared at 12 months from start of treatment using the fisher's exact test

    Measured: 12 months following BNS-RAP

Secondary outcomes (3)
  1. Potency Rates With or Without Assistance in the Control Group Versus Maintenance MUSE or Maintenance Viagra

    Potency rates with or without assistance in the control group versus maintenance MUSE or maintenance Viagra were compared at each of 6 and 18 months

    Measured: At 6 and 18 months

  2. SHIMS-5 Scores in the Control Groups Versus Maintenance MUSE or Maintenance Viagra Groups

    Median and range of SHIM scores evaluated at 1, 3, 6, 9, 12, and 18 months. SHIMS-5 is the Sexual Health Inventory for Men, which includes 5 questions that are scored from 1 to 5 each. The total score is obtained by adding all five response scores, and can range from 5 to 25 when all 5 questions are answered. Questions that are left unanswered are scored as a 0, and can result in an overall score lower than 5 (as low as 0). Higher scores are more desirable. A Score of 22-25 = no ED, 17-21=Mild ED, 12-16=Mild to moderate ED, 8-11=Moderate ED, and 5-7 =Severe ED (ED=Erectile Dysfunction). There are no sub-scale scores within this questionnaire.

    Measured: At 1, 3, 6, 9, 12, and 18 months

  3. Penile Length

    measurement of penile length in centimeters

    Measured: At pre-treatment and 18 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing sildenafil citrate, alprostadil and robotic-assisted laparoscopic surgery in people with Prostate Cancer and Male Erectile Disorder, run by City of Hope Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 2 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Potency Rates (Ability to Obtain an Erection Sufficient for Penetration) Without Assistance Compared Between Patients in All Three Arms of the Study at 12 Months (time frame: 12 months following BNS-RAP). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jan 2019.
