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

Single center, open label, pilot study. After screening and baseline testing, eligible patients will undergo transarterial embolization of the prostatic vasculature. Each patient will undergo a single embolization procedure.

After completion of treatment in the first 2 patients and a review of follow-up assessments after 7 days, subsequent patients will be enrolled if no safety concerns have arisen in the first 2 patients. Patients will be enrolled until 15 patients have undergone treatment. The patients will undergo MRI, contrast enhanced ultrasound and computerized tomography (CT) angiograpy/intra-procedural cone beam CT as required.

Ekobi Embolization MIcrospheres is administered via selective angiography and Prostatic Artery Embolization (PAE), a minimally invasive technique for reducing symptoms from Benign Prostatic Hyperplasia (BPH) to achieve near stasis in the target vasculature. Contrast Enhanced Ultrasound (CEU) and angiographic runs will be used to confirm anatomy at the time of embolization.

Magnetic resonance imaging (MRI) and CEUS is used to assess changes in prostate volume and in central gland enhancement characteristics using 3D volume assessment software.

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

46 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Sampling Method

Non-Probability Sample
