Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This randomized controlled trial aims to evaluate the safety and efficacy of the Optilume® drug-coated balloon (DCB) in the treatment of bulbar urethral strictures. The trial includes adult male participants who have not received prior treatment for urethral strictures. Participants will be randomly assigned to one of two treatment groups: Optilume DCB or standard direct visual internal urethrotomy (DVIU).

The primary objective of the study is to compare the recurrence rate of urethral strictures at 12 months between the two groups. Secondary objectives include assessing patient-reported outcomes (using USS-PROM, IPSS, and IIEF-5), urethral patency (via Qmax and post-void residual volume), and safety (monitoring adverse events).

Follow-Up Schedule:

At Diagnosis: Baseline assessments will include cystoscopy, uroflowmetry (Qmax), post-void residual (PVR), patient-reported outcomes (USS-PROM, IPSS, and IIEF-5), and demographic data (age, sex, BMI, comorbidities, and smoking status). Informed consent will also be obtained.

Day 3 (Foley Removal): Participants will return for catheter removal. 6-Month Follow-Up: Assessments will include Qmax, PVR, and patient-reported outcomes (USS-PROM, IPSS, and IIEF-5).

12-Month Follow-Up: Final assessments will include cystoscopy, Qmax, PVR, and patient-reported outcomes (USS-PROM, IPSS, and IIEF-5).

The study will recruit 140 participants across multiple sites, with recruitment anticipated to span approximately 17.5 months. Data will be analyzed using Kaplan-Meier survival curves to compare recurrence rates, and log-rank tests will be used to assess statistical significance. Modified Poisson regression will be applied to evaluate potential confounders.

This study aims to provide robust evidence on the effectiveness of Optilume DCB in reducing stricture recurrence, improving patient outcomes, and offering a safe alternative to standard treatment.

Participants

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Optilume Drug-Coated Balloon (DCB)

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.

Group Type EXPERIMENTAL

Optilume DCB

Intervention Type DEVICE

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.

Standard Direct Visual Internal Urethrotomy (DVIU)

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

Group Type ACTIVE_COMPARATOR

Standard Direct Visual Internal Urethrotomy (DVIU)

Intervention Type PROCEDURE

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