Prostate Artery Embolization Compared to Holmium Laser Enucleation of the Prostate for Benign Prostatic Hyperplasia

January 21, 2020 updated by: Germans Trias i Pujol Hospital

Prospective, Controlled Investigation of Prostate Artery Embolization Compared to Holmium Laser Enucleation of the Prostate for the Treatment of Symptomatic Benign Prostatic Hyperplasia

The purpose of this study is to evaluate improvement of symptoms from benign prostatic hyperplasia (BPH) as assessed by the International Prostate Symptom Score (IPSS) for prostate artery embolization (PAE) with microspheres (Embozene™, 400µm) compared to conventional Holmium laser enucleation of the prostate (HoLEP).

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 is a prospective randomized controlled study that collects data of patients with benign prostatic hyperplasia that are treated with prostatic artery embolization (PAE) or with Holmium laser enucleation of the prostate (HoLEP). For PAE a catheter is placed in the prostate artery, a fluid containing thousands of tiny particles (microspheres) is injected through the catheter into these small arteries which nourish the prostate. The injected microspheres will slow the blood flow to the prostate. For HoLEP a Holmium laser will be used to enucleate the prostatic hyperplasia trough the urethra. Clinical follow-up include clinical visit after 1, 6 and 12 months. Acute as well as long term complications will be recorded. The patients fill in the questionnaires for urologic disease. Urodynamic examination will record functional outcome.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Improvement of symptoms assessed by International Prostate Symptom Score (IPSS)
Time Frame: Baseline to 6 months after procedure
Change in prostatic symptoms using the International Prostate Symptom Score (IPSS). IPSS score goes from 0 to 35. Higher values mean worse outcome (prostate symptons)
Baseline to 6 months after procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Maximum urinary flow
Time Frame: Baseline to 6 months after procedure
Maximum urinary flow rate (Qmax). Evaluated in milliliter per seconds (mL/s).
Baseline to 6 months after procedure
Post-void residual urinary volume
Time Frame: Baseline to 6 months after procedure
Post-void residual urinary volume (PVR). Post-void urinary volume: evaluated in milliliters (mL)
Baseline to 6 months after procedure
Prostate specific antigen (PSA)
Time Frame: Baseline to 6 months after procedure
Determination in plasma of the prostate specific antigen (PSA)
Baseline to 6 months after procedure
Procedure related adverse events
Time Frame: Baseline to 6 months after procedure
Evaluation of Procedure related adverse events assessed by Clavien-Dindo modified score. Clavien Dindo modified score: the score goes from 1 to 5. Higher values mean worse outcome (surgical complications)
Baseline to 6 months after procedure
Procedure related effects on sexual function
Time Frame: Baseline to 6 months after procedure
Changes in sexual function assessed by International Index of Erectile Function (IIEF) score. IIEF: the score goes from 6 to 75. Lower values mean worse outcome (overall male sexual function).
Baseline to 6 months after procedure
Procedure related effects on urinary continence
Time Frame: Baseline to 6 months after procedure
Changes in urinary continence assessed by the International Consultation on Continence Questionnaire Short Form (ICIQ-SF). ICIQ-SF: score goes from 0 to 21. Higher values mean worse outcome (urinary continence)
Baseline to 6 months after procedure
