NCT ID: NCT05719285

Last Updated: 2024-01-02

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE4
• Total Enrollment: 100 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-12-06
• Study Completion Date: 2023-06-08

Brief Summary

The goal of this clinical trial is to evaluate the outcomes of differing durations of antibiotic prophylaxis with bladder onabotulinumtoxinA injection in patients with refractory overactive bladder.

The main question it aims to answer are:

• Is the incidence of post-procedure UTI similar between single-dose and multi-day durations of peri-procedural antibiotics?

Participants will be randomized to single-dose versus multi-day dose of antibiotic prophylaxis with bladder onabotulinumtoxinA injection.

Researchers will compare incidence of UTI in each group to see if there is a significant difference.

Detailed Description

• After informed consent is obtained, urinalysis will be collected. Post-void residual will also be assessed by bladder scan if not already documented in the electronic medical record in the prior three months.
• Patients with positive urinalysis and symptomatic for UTI will be excluded from the study.
• Patients will be randomized in a 1:1 ratio to one of two groups.

• Group 1 will receive one dose of antibiotic prior to bladder onabotulinumtoxinA injection.
• Group 2 will receive one dose of antibiotic prior to bladder onabotulinumtoxinA injection.
• The same antibiotic will be continued for 3 days of total antibiotic administration with additional doses prescribed to the patient's pharmacy.
• Bladder onabotulinumtoxinA injection and dosing will be completed based on the surgeon's standard technique and template.
• Bladder onabotulinumtoxinA injection will be completed by staff or fellows in the Female Pelvic Medicine and Reconstructive Surgery division of the Genitourinary and Kidney Institute.
• Patients will be followed for 4 weeks after the procedure.
• At 4 weeks study investigators will contact the patient by phone to evaluate for any UTIs or adverse events not previously reported by the patient during the study period.
• Chart review will occur at 4 weeks to assess for any unreported events.
• Other than this additional phone call, post-operative patient management will not deviate from the standard of care.
• Patients will be instructed to report symptomatic UTIs, urinary retention, or any other adverse events related to onabotulinumtoxinA or antibiotic to investigators.
• Patients that report symptoms suggestive of a UTI will result in obtaining a urine culture.
• Symptomatic, culture proven UTIs will be treated with appropriate antibiotics per the current AUA guidelines.
• Symptoms suggestive of urinary retention, such as increased urinary frequency, voiding small amounts of urine, or feelings of incomplete bladder emptying, will result in obtaining a post void residual (PVR) and urinalysis.
• Patients will undergo teaching to perform self, clean intermittent catheterization of the bladder per the discretion of the operating surgeon.
• Any adverse reactions to the prescribed antibiotic will result in discontinuation of the antibiotic and managed according to the severity of the reaction.
