About this study

Official title: Evaluation of Intradetrusor AbobotulinumtoxinA and IncobotulinumtoxinA Efficacy and Safety in Women With Overactive Bladder and Urge Urinary Incontinence and the Value of Local Anesthesia for Pain Reduction

A randomized, single blind, non-inferiority clinical study was performed evaluating the efficacy and safety of AbobotulinumtoxinA vs. IncobotulinumtoxinA intradetrusor injections in women with overactive bladder and urge urinary incontinence. Also the effect of local anesthesia on pain level of the procedure was assessed.

Read the detailed description

In the described prospective, clinical trial, approved by the National Medical Ethics Committee (protocol number: 0120-44/2018/5; date of approval: 22/02/2018), female patients were enrolled, followed by signed informed consent.

Before treatment patients underwent history and physical examination. Before botulinum toxin injection each patient completed three questionnaires, UDI-6 (Urogenital Distress Inventory), IIQ-7 (Incontinence Impact Questionnaire), I-QOL (Incontinence Quality of Life). The total score of each questionnaire was considered. Before botulinum toxin injection, urinalysis was performed to check for a urinary tract infection (UTI). For those presenting with UTI, treatment was postponed until the UTI was treated and a repeat urinalysis was performed. Nitrofurantoin 100 mg twice daily per os was given prophylactically on the day of the procedure. Patients were randomised to receive either 300 units of AbobotulinumtoxinA (Dysport®) or 100 units of IncobotulinumtoxinA (Xeomin®). They were further randomised to receive local anesthesia or placebo. 30 minutes before the procedure the bladder was instilled with either 40 ml 1% lidocaine solution using a 16Fr urethral Foley catheter or with 40 ml 0.9% NaCl solution. All patients received urethral lubrication gel. Using rigid cystoscopy, normal saline was used to dilute the vial to 20 ml. A total of 20 evenly distributed intradetrusor injections, 1 ml per site, were performed, 2 of them included the trigone area. During the procedure the patients graded the pain level of every injection on a Visual Analog Scale (VAS). All patients were treated in an outpatient clinic and by one experienced surgeon.

After 1 to 2 weeks patients were seen for evaluation of systemic side effects, physical examination, measurement of residual urine and urinalysis to eventually diagnose and treat a urinary tract infection. After 4 months patients were seen to evaluate the treatment result and complete the questionnaires, IIQ-7, UDI-6, patient satisfaction survey and I-QOL. Side effects were monitored for 5 months after the procedure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of Intradetrusor AbobotulinumtoxinA and IncobotulinumtoxinA

    Questionnaire scores of UDI-6 (Urogenital Distress Inventory), IIQ-7 (Incontinence Impact Questionnaire) and I-QOL (Incontinence Quality of Life) will be evaluated before and after the procedure for non-inferiority of the two drugs.

    Measured: 5 months

Secondary outcomes (2)
  1. The Value of Local Anesthesia for Pain Reduction

    During the procedure the patients graded the pain level of every injection on a Visual Analog Scale (VAS). The total score of each questionnaire will be evaluated for non-inferiority of placebo in comparison to local anesthesia.

    Measured: The day of procedure

  2. Safety of Intradetrusor AbobotulinumtoxinA and IncobotulinumtoxinA

    Frequency of adverse events (urinary retention, urinary tract infection)

    Measured: 5 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing AbobotulinumtoxinA 300 UNT, IncobotulinumtoxinA 100 UNT and Lidocain in people with Overactive Bladder, run by Niko Kavcic at 1 site in Slovenia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation of Intradetrusor AbobotulinumtoxinA and IncobotulinumtoxinA (time frame: 5 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06250543, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2024.
