NCT06827210

Brief Summary

This randomized controlled trial investigates the effectiveness and safety of the Optilume® drug-coated balloon (DCB) compared to standard direct visual internal urethrotomy (DVIU) in the treatment of bulbar urethral strictures. The primary objective is to assess freedom from repeat intervention at 12 months. Secondary objectives include evaluating urethral patency, urinary symptoms, and sexual function through objective measures (Qmax, PVR, cystoscopy) and patient-reported outcomes (USS-PROM, IPSS, IIEF-5). The study will recruit 140 participants across multiple sites, with follow-ups conducted at 6 and 12 months. This trial seeks to provide evidence for Optilume DCB as a safe and effective alternative to standard treatment.

Outcome Measures

Primary Outcomes (1)

  • Freedom from Repeat Intervention at 12 Months

    "The primary outcome is the proportion of participants who remain free from repeat intervention for urethral stricture recurrence at 12 months following treatment. Repeat intervention is defined as any procedure to address stricture recurrence, such as dilation, DVIU, or urethroplasty. Referrals for repeat interventions made within the 12-month follow-up period will also be included, even if the procedure itself is scheduled beyond the 12-month mark."

    12 months post-intervention

Secondary Outcomes (8)

  • Urethral Patency Assessed via Cystoscopy at 12 Months

    12 months post-treatment

  • Maximum Urinary Flow Rate (Qmax) at 12 Months

    12 months post-treatment

  • Post-Void Residual (PVR) Volume at 12 Months

    12 months post-treatment

  • Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROM)

    12 months post-treatment

  • International Prostate Symptom Score (IPSS) at 12 Months

    12 months post-treatment

  • +3 more secondary outcomes

Study Arms (2)

Optilume Drug-Coated Balloon (DCB)

EXPERIMENTAL

Participants in this arm will receive treatment with the Optilume drug-coated balloon (DCB), which combines mechanical dilation with localized drug delivery of paclitaxel to reduce stricture recurrence and promote healing.

Device: Optilume DCB

Standard Direct Visual Internal Urethrotomy (DVIU)

ACTIVE COMPARATOR

Participants in this arm will undergo standard Direct Visual Internal Urethrotomy (DVIU), a commonly performed endoscopic procedure for the treatment of bulbar urethral strictures.

Procedure: Standard Direct Visual Internal Urethrotomy (DVIU)

Interventions

Optilume DCB is a drug-coated balloon catheter designed for the treatment of bulbar urethral strictures. It combines mechanical dilation with localized drug delivery to reduce stricture recurrence and promote urethral healing. The balloon is coated with paclitaxel, an antiproliferative agent, to minimize scar tissue formation and improve treatment outcomes.

Also known as: Drug-coated balloon
Optilume Drug-Coated Balloon (DCB)

Standard Direct Visual Internal Urethrotomy (DVIU), also known as Sachse Internal Urethrotomy, is a minimally invasive endoscopic procedure for treating urethral strictures.
