Objectives Primary - To determine the rate of erectile function (defined as the ability to achieve and maintain an erection for intercourse without pharmacological assistance) at 1 year following bilateral nerve-sparing robotic-assisted prostatectomy (BNS-RAP) without postoperative maintenance pharmacotherapy in patients with nonmetastatic prostate cancer.
- To describe whether early postoperative maintenance pharmacotherapy with sildenafil citrate can improve return of erectile function at 1 year postoperatively in these patients.
- To describe if early postoperative maintenance pharmacotherapy with sildenafil citrate can decrease the time-to-return of erectile function in these patients.
Secondary - To describe whether early postoperative maintenance pharmacotherapy with alprostadil can improve return of erectile function at 1 year postoperatively in these patients.
- To describe if early postoperative maintenance pharmacotherapy with alprostadil can decrease the time-to-return of erectile function in these patients.
- To compare sexual function quality of life in patients undergoing early postoperative maintenance pharmacotherapy to those without early postoperative maintenance pharmacotherapy.
- To compare the rate of potency at 1, 3, 6, 9, 12, and 18 months in patients using sildenafil citrate versus alprostadil for early postoperative maintenance pharmacotherapy.
- To describe the dropout rate for alprostadil maintenance pharmacotherapy secondary to urethral pain in patients using 2% lidocaine lubricant.
- To describe if penile length is decreased following BNS-RAP.
- To describe if penile length at 1 year is different in patients who have return of potency versus those who have no return of potency.
Entry Criteria Disease Characteristics:
- Diagnosis of prostate cancer
- Stage T3 or less disease
- Gleason score ≤ 8 based on final surgical pathological biopsy results
- Nonmetastatic disease as confirmed by CT scan, bone scan, or lymph node biopsy
- Concurrently enrolled on the Prostate Database Study (protocol no. 00149) at the City of Hope National Medical Center
- Scheduled to undergo bilateral nerve-sparing robotic-assisted prostatectomy
- Was able to achieve erections sufficient for intercourse prior to surgery AND has an Erectile Dysfunction Penile Assessment (SHIMS-5) score ≥ 22
Prior/Concurrent Therapy:
- No concurrent nitrate therapy (including oral sublingual nitrates) for coronary artery disease
- No prior hormonal treatment for prostate cancer or low serum testosterone
- No concurrent cytochrome P450 3AY inhibitors (i.e., cimetidine, erythromycin, ketoconazole, or protease inhibitors)
Patient Characteristics:
- Willing to participate on study for 18 months
- Able to maintain follow-up care at the City of Hope National Medical Center for visits 1, 3, 6, 9, 12, and 18 months post surgery
- No allergy to the prostaglandin PGE1, lidocaine, or sildenafil citrate
Expected Enrollment 204Outcomes Primary Outcome(s)Potency (defined as ability to attain an erection sufficient for penetration) rates without assistance at 12 months after bilateral nerve-sparing robotic-assisted prostatectomy (BNS-RAP) in patients receiving maintenance sildenafil citrate
Secondary Outcome(s)Potency rates at 12 months after BNS-RAP in patients receiving maintenance alprostadil Potency rates with or without assistance at 1, 3, 6, 9, and 18 months after BNS-RAP Erectile Dysfunction Penile Assessment (SHIMS-5) scores at 1, 3, 6, 9, and 18 months after BNS-RAP Penile length at randomization and at 1, 3, 6, 9, and 18 months after BNS-RAP Dropout rates in the alprostadil maintenance therapy group secondary to penile burning/pain after alprostadil usage
Outline Patients receive 2 doses of intraurethral alprostadil prior to undergoing bilateral nerve-sparing robotic-assisted prostatectomy (BNS-RAP). Within 2 weeks after surgery, patients are randomized to 1 of 3 treatment arms. In arms I and III, treatment begins at the first postoperative visit. - Arm I: Patients receive intraurethral alprostadil once daily for up to 9 months in the absence of unacceptable toxicity. Patients also receive a set of 3 doses of oral sildenafil citrate at least 48 hours apart monthly for up to 18 months.
- Arm II: Patients receive a set of 3 doses of oral sildenafil citrate at least 48 hours apart monthly for up to 18 months.
- Arm III: Patients receive oral sildenafil citrate once daily for up to 9 months in the absence of unacceptable toxicity. Patients also receive a set of 3 doses of oral sildenafil citrate at least 48 hours apart monthly for up to 18 months.
Patients undergo assessment of erectile dysfunction, penile length, rate of urinary incontinence, and sexual function quality of life at baseline (preoperatively) and periodically during study. Patients are also assessed using a self-reported diary that records daily maintenance therapy, nocturnal erections, pharmacotherapy for intercourse, and the results of pharmacotherapy usage (i.e., no erection, erection sufficient for penetration, or erection insufficient for intercourse). After completion of study therapy, patient are followed periodically for up to 18 months.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
