Prostate Artery Embolization (PAE) for Treatment of Benign Prostatic Hyperplasia

April 15, 2019 updated by: Ziv Haskal, MD, University of Virginia

Prostate Artery Embolization Safety and Efficacy: A Pilot Study

The purpose of this project is to evaluate the safety, efficacy, and feasibility of performing prostatic artery embolization (PAE) using endovascular techniques and particle embolics in men suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH).

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 pilot study is a prospective, non-randomized clinical trial assessing the safety and feasibility of prostatic artery embolization. Fifty adult male subjects will be enrolled and treated in this study. Patients who provide informed consent and are deemed eligible for participation will undergo prostatic artery embolization in the Interventional Radiology department at the University of Virginia. After performing an angiogram to identify the prostatic arteries, tiny particles known as Embozene Microspheres will be injected into the prostatic artery. Injecting these particles into the prostatic artery will slow blood flow to the prostate and thus shrinking the size of the prostate. By shrinking the size of the prostate, it is hopeful that it will provide relief of lower urinary tract symptoms due to BPH. Subjects will be followed for 2 years as part of their participation in this study.

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.

Ages Eligible for Study

45 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Experimental: Embozene Microspheres
Embozene Microspheres are spherical particles consisting of a hydrogel core and a poly nanocoat that will be used during study procedure, Prostatic Artery Embolization (PAE) to reduce or eliminate bloodflow to the prostate.
Device: Embozene Microspheres
Minimally invasive intra-arterial administration of particle embolics into prostate arteries under fluoroscopy and cone-beam CT imaging guidance.
