Read the detailed description

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.

Study arms

  • Active comparator
    Device: The ProVee Urethral Expander System

    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

  • Sham comparator
    Sham: Ureteroscope and urethral access sheath

    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

  • Other
    Crossover ProVee Urethral Expander System

    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

Interventions

  • DeviceProVee Urethral Expander System

    ProVee Expander is placed in prostatic urethra to relieve obstruction due to BPH.

    Also known as: ProVee Expander, ProVee

  • ProcedureUrethral Access Sheath

    The Urethral Access Sheath is introduced into the prostatic urethra to simulate the placement of the ProVee Expander.

What researchers measure

Primary outcomes

  1. 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

  2. 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

  3. 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

  4. 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

This Clinical Study Protocol and Statistical Analysis Plan has been redacted in accordance with the regulations at 42 CFR 11.48(a)(5). Note that the all cause mortality results, the CEC adjudicated that the death was related to a pre-existing condition. For the serious adverse events, no reported serious adverse events have been adjudicated by CEC as device or procedural related.

Participant flow

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.

Adverse events

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.
