A study to evaluate the safety, performance, and effectiveness of the ProVee Urethral Expander System (Investigational Device) when used in subjects with symptomatic urinary obstruction related to benign prostatic hyperplasia (BPH).
This is a prospective, multi-center, randomized, single-blind, sham-controlled study to evaluate the safety, performance, and effectiveness of the ProVee Urethral Expander System (Investigational Device) when used in subjects with symptomatic urinary obstruction related to benign prostatic hyperplasia (BPH). Subjects are assigned to their treatment arm using an unbalanced (2 ProVee:1 Sham) randomization stratified by Investigational Sites.
783 studies on the registry are indexed under Prostatic Hyperplasia; 174 are open to participants now.
This study's enrollment of 221 is above the median of 97 across 593 interventional studies indexed under Prostatic Hyperplasia.

Exclusion Criteria:
The ProVee Urethral Expander System consists of two components: a nitinol Expander implant and a 19Fr Delivery System designed to allow the Expander to be deployed under direct vision for the treatment arm.
Device: ProVee Urethral Expander System
An ureteroscope housed within the inner lumen of an urethral access sheath will be used under direct vision for the Sham procedure.
Procedure: Urethral Access Sheath
All subjects shall be unblinded following the 3 month follow-up visit. Those subjects randomized to the Sham Arm will be given the opportunity to "crossover" to the ProVee Urethral Expander System.
Device: ProVee Urethral Expander System
ProVee Expander is placed in prostatic urethra to relieve obstruction due to BPH.
Also known as: ProVee Expander, ProVee
The Urethral Access Sheath is introduced into the prostatic urethra to simulate the placement of the ProVee Expander.
Safety: Adverse Events (Time Frame: Procedure to 12 Months)
This includes the rate of device or procedure related serious adverse events through 12-months.
Time frame: Procedure - 12 months
Safety: Number of Participants With Need for Urinary Catheterization (Time Frame: >7 Days Post Procedure)
The rate of extended post-operative urinary catheterization for inability to void among patients treated with the ProVee device.
Time frame: 7 days post treatment through to 12 months
Effectiveness: Number of Participants With Reduction in BPH Symptoms Compared to Sham (Time Frame: Procedure to 3 Months)
The ProVee Treatment Group will be considered superior to the Sham Treatment Group when the mean 3-month improvement from baseline score for the IPSS symptom questionnaire demonstrates a minimum statistical margin of 25% compared to mean improvement from baseline for the Sham Treatment Group alone.
Time frame: Procedure to 3 months
Effectiveness: Number of Participants With Symptoms Improvements (Time Frame: Procedure to 12 Months)
The mean percent change in IPSS in the treatment arm is at least 30% improvement over the patient's pre-treatment baseline score.
Time frame: Procedure to 12 months
All primary endpoint results are now entered. This Clinical Study Protocol and Statistical Analysis Plan has been redacted in accordance with the regulations at 42 CFR 11.48(a)(5). All SAEs reported have been adjudicated by CEC as not device or procedural related.

Collected over All subjects are followed for 3 months until the co-primary effectiveness endpoints are evaluated. After their 3-month visit, all subjects are unblinded to their treatment assignment. Subjects assigned to the ProVee Device will continue to be followed up to 60 months post implantation. Following unblinding, subjects assigned to the control arm may (crossover to the active treatment). After being treated, Crossover Subjects will be followed using the same schedule used with the ProVee Device.. Non-serious events are listed at a 0% frequency threshold.
