Trial Outcomes & Findings for Optilume™ BPH Catheter System in Men With Symptomatic BPH (NCT NCT04131907)
NCT ID: NCT04131907
Last Updated: 2025-04-09
Results Overview
The primary efficacy endpoint was the improvement in International Prostate Symptom Score (IPSS) at 12 months in the Optilume BPH arm compared to the improvement in IPSS at 3 months in the Sham arm with a super-superiority margin on 25%. The IPSS contains the well-validated, highly reliable and responsive American Urological Association symptom score (AUASS) assessment to identify the severity of BPH symptoms. The first seven questions in the IPSS address frequency, nocturia, weak urinary stream, hesitancy, intermittence, incomplete emptying, and urgency, and scored on a 6-point scale (0 to 5). The IPSS can be interpreted as follows: 0-7 mildly symptomatic, 8-19 moderately symptomatic, and 20-35 severely symptomatic. The IPSS also includes an eighth question that is designed to assess the degree of "bother" associated with the subject's urinary symptoms. Answers range from "delighted" to "terrible" (0-6). This question is not included in the calculation of the main IPSS score.

Participant Flow
162 subjects will be randomized and/or treated in the study at up to 30 clinical sites in the United States and Canada. Up to 625 subjects will be enrolled (i.e. consented) in the study in order to identify 162 eligible subjects to be randomized and/or treated. All subjects treated with the Optilume BPH Catheter System will be followed annually through 5 years. Study duration is approximately 8 years.
Any required procedures performed before obtaining informed consent as part of the standard of care may be used in lieu of the study tests. Subjects who require a washout period should have these evaluations, with the exception of informed consent, conducted following completion of the washout period. Subjects who cannot tolerate a drug washout or are considered high risk from the drug washout should be excluded from the study.

TEST ARM - Optilume™ BPH Catheter Treatment in Men With Symptomatic BPH System
Subjects randomized to the Test arm were treated with the Optilume™ BPH Catheter System.
Subjects were evaluated at baseline, immediately post-procedure, at Foley removal, 14 days, 30 days, 3 months, 6 months, 12 months and annually through 5 years post-procedure.
Randomized subjects were blinded to the treatment assignment through the 12-month Follow-up Visit.
|
CONTROL ARM - Sham Treatment in Men With Symptomatic BPH.
Subjects randomized to the Control arm received a sham procedure. A cystoscopy was performed followed by insertion of the sham device (21 Fr Optilume BPH, Prostatic Pre-dilation Catheter with a modified catheter hub to prevent inflation of the balloon) within the sheath.
Subjects were evaluated at baseline, immediately post-procedure, at Foley removal, 14 days, 30 days, 3 months, 6 months and 12 months.
Randomized subjects were blinded to the treatment assignment through the 12-month Follow-up Visit.
Subjects randomized to the Control arm were allowed to crossover to the Test arm (treated with Optilume BPH) if they met the eligibility criteria after completing the 3-Month Follow-up Visit and prior to the close of the 12-Month visit window. Data for these subjects is reported seperately as the Crossover Cohort.
|
Pharmacokinetic (PK) Arm
Subjects in the Pharmacokinetic (PK) arm of the study were not randomized and were treated with the Optilume BPH Catheter System.
Small amounts of blood, urine and semen were collected for pharmacokinetic testing and sperm quality testing. Subjects are followed through 5-years post-procedure.
A total of 15 subjects were included in the PK arm, with one of those subjects also being included in the Crossover cohort. For this summary of the study results, 14 subjects will be indicated as participating in the PK arm to prevent the PK Crossover subject from being counted twice in the numbers.
A central core laboratory was utilized for analysis of the PK samples.
