Merit Medical Systems, Inc.
  Purpose
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 prostatic artery embolization (PAE) using Embosphere Microspheres compared to conventional transurethral resection of the prostate (TURP).

Condition Intervention Phase
Benign Prostatic Hyperplasia Device: Embosphere Microspheres Procedure: TURP Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prospective, Controlled Investigation of Prostate Artery Embolization With Embosphere Microspheres Compared to Transurethral Resection of the Prostate for the Treatment of Symptomatic Benign Prostatic Hyperplasia

Primary Outcome Measures:
  • IPSS Score [ Time Frame: 12 months ]
    The primary endpoint will be improvement of symptoms from BPH evaluated using the IPSS at 12 months post procedure.


Secondary Outcome Measures:
  • Duration of hospitalization post procedure [ Time Frame: 1 month ]
  • Duration of post procedure catheterization [ Time Frame: 1 month ]
  • Overall and procedure related adverse events [ Time Frame: 12 months ]
  • Safety [ Time Frame: 12 months ]
    Safety will be evaluated throughout the initial 12 months of the study by assessing adverse events, as well as changes in laboratory values, and finding on physical examination.


Other Outcome Measures:
  • Change from baseline in peak urine flow rate (Qmax) [ Time Frame: 12 months ]
  • Change from baseline in erectile function using the International Index of Erectile Function (IIEF) [ Time Frame: 12 months ]
  • Change from baseline in mean prostate volume, as determine by MRI [ Time Frame: 12 months ]
  • Change from baseline in post-void residual urinary volume (PVR) [ Time Frame: 12 months ]
  • Change in baseline from prostate specific antigen (PSA) [ Time Frame: 12 months ]

Estimated Enrollment: 186
Study Start Date: July 2013

Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
