Safety and Efficacy of OCL 503 in Prostate Artery Embolization

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02509975
Recruitment Status : Completed
First Posted : July 28, 2015
Last Update Posted : August 8, 2018

Brief Summary:
This is a prospective, pilot, open-label, uncontrolled, non-randomized safety and effectiveness study of OCL 503 in men with BPH.

Condition or disease Intervention/treatment Phase
Benign Prostatic Hyperplasia Benign Prostatic Hypertrophy Device: Prostate artery embolization. Not Applicable

Detailed Description:

Prior to entering the study, all patients will undergo pre-study assessments including compliance with inclusion and exclusion criteria, laboratory assessments, IPSS, uroflowmetry, IIEF, and MRI pelvic imaging. Following conventional catheter angiography with cone-beam CT to confirm catheter placement and prostatic vasculature, each patient will undergo transarterial embolization with OCL 503. OCL 503 will be administered intra-arterially via microcatheter until there is stasis of blood flow.

Patient assessments include blood work, IPSS, uroflowmetry, IIEF, MRI and patient interviews conducted at 3 months, 6 months, and 12 months post embolization.

Arm Intervention/treatment
Experimental: Prostate Artery Embolization
Transarterial administration of OCL 503 to the arteries feeding the prostate.
Device: Prostate artery embolization.
Embolization of the prostatic vasculature with OCL 503 using a microcatheter.

Primary Outcome Measures :
  1. Safety of OCL 503 as measured by Adverse Events reporting. [ Time Frame: 12 months ]
    Measurement of device related adverse events post embolization of the prostatic vasculature, at 30 days.

  2. International Prostate Symptom Score (IPSS) [ Time Frame: 12 months ]
    Measurement of IPSS at 12 months post embolization of the prostatic vasculature with OCL 503.

Secondary Outcome Measures :
  1. Tissue Response [ Time Frame: 12 months ]
    Measurement in the change in size of the prostate by MRI at 12 months post embolization of the prostatic vasculature with OCL 503.

  2. Uroflowmetry [ Time Frame: 12 months ]
    Measurement of Qmax, post-voiding bladder retention (PVR) at 12 months post embolization of the prostatic vasculature with OCL 503.

  3. International Index of Erectile Function (IIEF) [ Time Frame: 12 months ]
    Measurement of IIEF by questionnaire at 12 months post embolization of the prostatic vasculature using OCL 503.
