Phase II Study to Evaluate the Safety and Efficacy of Prostatic Artery Embolization

July 29, 2026 updated by: H. Lee Moffitt Cancer Center and Research Institute

Phase II Study to Evaluate the Safety and Efficacy of Prostatic Artery Embolization in Patients With Localized Prostate Carcinoma and Obstructive Lower Urinary Tract Symptoms

This is a Phase II prospective clinical trial in which patients with prostate carcinoma and obstructive lower urinary tract symptoms electing for radiation therapy will undergo Prostatic Artery Embolization (PAE) prior to treatment. PAE will be administered by Interventional Radiology. Patients will be seen for follow-up at 6 weeks and 12 weeks following PAE after which they will start definitive radiotherapy. After completion of radiotherapy the patient will be seen at 12 weeks

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

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Ability to understand and the willingness to sign a written informed consent document
  • Prostate larger than 60 grams but less than 150 grams, as assessed by imaging scans
  • American Urologic Association (AUA) or International Prostate Symptom Score (IPSS) Score ≥ 15

Exclusion Criteria:

  • Patients with Gleason Grade Group 1 or 2 PCa who select active surveillance as their cancer management method.
  • Receiving androgen deprivation therapy (ADT)
  • Patients with unfavorable intermediate (Gleason Grade Group 3) or high risk localized PCa (Gleason Grade Groups 4 and 5)
  • Receiving any investigational agents for the explicit purpose of prostatic size reduction
  • Inability to receive prostatic artery embolization (PAE) within 6-12 weeks of definitive radiation therapy
  • Active urinary tract infection (UTI)
  • History of severe allergic reaction to intravenous contrast media (iodinated and gadolinium- based) or any agents used during the PAE; patient cannot be medicated against allergic reaction prior to PAE.

  • Inability to have multi-parametric magnetic resonance imaging (mpMRI)
  • Prior transurethral resection of the prostate (TURP) within 2 years
  • Prostate size greater than or equal to150 grams
  • Vulnerable subjects (e.g., inmates and developmentally delayed adults) who are subjects for whom the study may be unsafe or whose rights may be violated with enrollment.

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

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

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.
Experimental: Prostatic Artery Embolization (PAE)
Participants who receive PAE with Merit Medical Embospheres.
Device: Merit Medical Embospheres
Prostatic Artery Embolization will performed as an outpatient procedure in Interventional Radiology. Bilateral selective pelvic angiograms will be performed to localize the prostatic arteries. Cone-beam or 3D computed tomography (CT) will be performed prior to embolization, if technically feasible and necessary. Embolization will be performed using Merit Medical Embospheres.
Radiation: Radiation Therapy
Patients will undergo standard of care definitive radiation therapy.

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
Change in International Prostate Symptom Score
Time Frame: At screening, Day of PAE, and 6 weeks & 12 weeks after PAE
Participants will take quality of life questionnaires including the International Prostate Symptom Score (IPSS)questionnaire to determine changes in prostate symptoms. Questionnaire will be taken at screening, Day 0- day of prostatic artery embolization (PAE), and at 6 weeks and 12 weeks after PAE. The IPSS asks the patient to rate urinary symptoms on a scale of 0-5, 0 indicating the participant has not had a symptom at all, and 5 indicating the symptom "almost always".
At screening, Day of PAE, and 6 weeks & 12 weeks after PAE

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
Prostate Volume Reduction after PAE
Time Frame: At 12 weeks
Prostate volume will be determined by MRI prior to PAE and at 12 weeks post PAE to determine changes in volume.
At 12 weeks
Change in American Urologic Association Score
Time Frame: At 18 weeks
Participants will take quality of life questionnaires including the American Urologic Association (AUA) test to assess genitourinary toxicity after PAE and radiation therapy. The AUA questionnaire asks the patient to rate urinary symptoms on a scale of 0-5, 0 indicating indicating the participant has not had a symptom at all, and 5 indicating the symptom "almost always".
At 18 weeks
