About this study

Investigator-initiated study to evaluate the safety and efficacy of prostate artery embolization for the treatment lower urinary tract symptoms in patients with benign prostatic hyperplasia

Read the detailed description

This is a phase I/II, single center, prospective, single arm, investigational study to evaluate the safety and efficacy of prostate artery embolization (PAE) for treatment of severe lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) in patients that have either failed or are intolerant to medical management. Once eligibility is confirmed, patients will undergo PAE with Embosphere Microspheres. Embolization will consist of a minimally invasive angiogram and treatment of the prostate arteries with the Embosphere particles to reduce blood flow to the prostate. Following treatment, patients will return for follow-up visits at 1, 6, 12, and 24 months post PAE.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Embosphere microparticles for prostate artery embolizationDevice

    Pelvic angiograms will be performed and microspheres delivered to the arteries supplying the prostate to alleviate symptoms of benign prostatic hyperplasia.

What is being measured

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

  1. Number of Participants With Adverse Events

    The study protocol was terminated before completion as the device was FDA approved and determined to be safe for the treated patient population.

    Measured: 12 months

Secondary outcomes (5)
  1. Change in International Prostate Symptom Score (IPSS)

    International Prostate Symptom Score change from baseline measured at 1 and 6 months. The IPSS scale grades lower urinary tract symptoms on a scale ranging from 0 (no symptoms) to 35 (severe). Patients answer 7 questions about symptoms they have had in the past month and grade each symptom severity for each question on a scale from 0 (not at all) to 5 (almost always). Change is reported as outcome measure time point minus baseline. A positive value indicates improved symptoms and negative value worsened symptoms.

    Measured: baseline, 1 month, 6 month

  2. Change in Post-void Residual (PVR) on Ultrasound

    PVR (mL) change from baseline measured at 1 and 6 months. Change is reported as outcome measure time point minus baseline. A negative value indicates less post-void residual and a positive value indicates greater PVR at each outcome time point.

    Measured: baseline, 1 month, 6 month

  3. Change in Peak Urinary Flow Rate (Qmax)

    Change in Qmax measured at 1 and 6 months. Change is reported as outcome measure time point minus baseline. A positive value indicates improved Qmax and negative value indicates decreased Qmax at each outcome time point.

    Measured: Baseline, 1 month, 6 month

  4. Change in International Index of Erectile Dysfunction (IIEF)

    IIEF score change from baseline measured at 1 and 6 months. International Index of Erectile Function (IIEF) is a scale grading erectile function based on 5 questions. Questions are answered from 1 (low function) to 5 (high function). Total scores range from 5 to 25. A total score of 5-7 is severe erectile dysfunction, 8 to 11 is moderate erectile dysfunction, 12 to 16 is mild to moderate erectile dysfunction, 17 to 21 is mild erectile dysfunction, and 22-25 is no erectile dysfunction. Change is reported as outcome measure time point minus baseline. A positive value indicates improved erectile function and a negative indicates worsened erectile function.

    Measured: baseline, 1 month, 6 month

  5. Change in Prostate Volume (PV)

    Change in prostate volume measured at 1 and 6 months. Change is reported as outcome measure time point minus baseline. A negative value indicates decreased prostate volume and a positive value indicates increased prostate volume.

    Measured: baseline, 1 month, 6 month

Questions about this trial

What is this clinical trial studying?

A study testing Embosphere microparticles for prostate artery embolization in people with Prostatic Hyperplasia, Benign and Enlarged Prostate With Lower Urinary Tract Symptoms, run by University of California, San Diego 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 12 inclusion and 21 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: finished, as of the sponsor's last update on 31 Mar 2020. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 Mar 2020). 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?

Number of Participants With Adverse Events (time frame: 12 months). 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 31 Mar 2020.
