Prostate Embolization for Benign Prostatic Hyperplasia

Benign Prostatic Hyperplasia Clinical Trial

Official title: Prostate Embolization for Benign Prostatic Hyperplasia

Status Completed

Clinical Trial Summary

This is a Phase I/II investigator sponsored FDA-approved Investigational Device Exemption protocol, with the primary goal of determining the safety of prostatic artery embolization (PAE) for benign prostatic hyperplasia. Our primary goal is to document the frequency of side effects, particularly bladder and rectal complications, which may occur as a result of this procedure. Secondarily, the study will provide preliminary data to determine its effectiveness in diminishing obstructive symptoms associated with BPH.

Clinical Trial Description

Objectives of the investigation

This study has a primary goal of determining the safety of prostatic artery embolization (PAE) for benign prostatic hyperplasia. Our primary outcome is the frequency of adverse events, particularly bladder and rectal complications, which may occur as a result of this procedure. Secondarily, the study will allow us to begin to determine its effectiveness in diminishing obstructive symptoms associated with BPH.

Duration of investigation

The investigation will enroll 30 patients, with a target enrollment period of less than 12 months. Each patient will be consented for follow-up up to 5 years, but each patient will reach the first important safety endpoint 1 week after treatment and the first clinical efficacy assessment 3 months after treatment.

Objectives

To determine the safety and effectiveness of prostate artery embolization for the treatment of BPH.

Description of study type

This is a prospective non-comparative treatment study of an initial cohort of 30 patients.

Study Population

The patients will be recruited from the urology practice at Georgetown University and from other urologists in the area and by patient self-referral. The study also will be announced on a study website, the content of which will be approved by the IRB at Georgetown University Medical Center.

The primary outcome is the absence of complications to the bladder, rectum or other pelvic structures detected in the first week after therapy. Each patient will be judged free of these adverse events or not. For those with an adverse event, the complication will be scored using the Society of Interventional Radiology (SIR) definitions. Descriptive statistics will be used to summarize these events, along with patient demographics and initial clinical status.

Appropriate parametric and non-parametric tests will be used to assess change in laboratory measures, urine flowmetry parameters, and scores from the IPSS and IIEF. Changes in prostate volumes and the estimated volume of devascularized tissue will be calculated for each patient and outcomes from the different embolics will be compared. Appropriate paired parametric and non-parametric tests will be used to determine statistical significance. A p value of 0.05 will be considered statistically significant. ;
