Summary

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).

Detailed description

The study will consist of a screening period in which patient eligibility will be determined and baseline assessments performed. Once eligibility is confirmed, patients will be enrolled within 4 weeks of baseline imaging to receive either TURP or PAE with Embosphere Microspheres. After treatment, patients will return for follow-up visits at Months 1, 3, 6, and 12. At each of these visits patients will complete IPSS and IIEF questionnaires and have a physical exam, laboratory assessments (including PSA), a DRE, and a transrectal ultrasound of the prostate. At each visit patients will have a cystoscopy and proctoscopy if medically indicated. Cystoscopy is necessary in all cases of hematuria (injury associated with bleeding). Proctoscopy is necessary in all cases of bleeding per the rectum. An MRI of the prostate will be conducted at the 3 and 12 month visits. Uroflowmetry testing will be performed at the 1 and 12 month visits, and at other visits if medically indicated. MRIs will be assessed by blinded Central Reviewers. The primary endpoint will be improvement of symptoms from BPH evaluated using the IPSS at 12 months post treatment. Patients will continue to be followed annually for up to 4 additional years. At a minimum, patients will be requested to complete the IPSS and International Index of Erectile Dysfunction (IIEF) questionnaires by telephone, email or mail once per year during this long term follow up period. Patients who are willing to return to the clinic will have a physical exam, MRI of the prostate, digital rectal exam (DRE), transrectal ultrasound of the prostate, PSA, and uroflowmetry testing performed each year. Treatments for LUTS due to BPH after the study treatment and 12 month follow up are complete will be documented during the long term follow up period to the extent possible. This long term follow up data will be summarized and submitted separately from the data for the initial 12 months of this study. Safety will be evaluated throughout the initial 12 months of the study by assessing adverse events, as well as changes in laboratory values, and findings on physical examination. Concomitant medication usage will be assessed. A follow up ECG will be performed at the 12 month visit. Patient recruitment is anticipated to take approximately 2 years. Duration of each patient's participation is expected to be 5 years, including a 4 year long term follow up period. The total duration of the study will be approximately 7 years, including long term follow up.
