About this study

Official title: Oral Phenazopyridine Versus Intravesical Lidocaine for Office OnabotulinumtoxinA Analgesia: A Randomized Controlled Trial

OnabotulinumtoxinA (Botox®) bladder injections are a highly effective treatment for overactive bladder and urgency urinary incontinence. The procedure is typically performed in the office setting with one of two medications to control comfort. However, the effectiveness of these medications has never been compared. The goal of this study is to determine which medication is better at providing comfort during bladder Botox® injections.

Read the detailed description

The primary aim of this randomized clinical trial is to compare the analgesic effect of oral phenazopyridine to that of intravesical lidocaine during intradetrusor injections of onabotulinumtoxinA performed for idiopathic overactive bladder. The investigators will achieve this by measuring the mean visual-analog pain scores (VAS) in women who are randomized to receive either oral phenazopyridine or intravesical lidocaine.

Secondary aims include assessment of:

  1. Overall Patient Satisfaction: To compare overall patient satisfaction with the onabotulinumtoxinA injection procedure in women randomized to pre-procedure oral phenazopyridine versus those randomized to intravesical lidocaine instillation.
  2. Ease of Procedure: To compare the physician's perception of ease of onabotulinumtoxinA injection procedure in women randomized to pre-procedure oral phenazopyridine versus those randomized to intravesical lidocaine instillation.
  3. Office Efficiency/Total Appointment Duration: To compare total appointment time or total time spent in an office exam/procedure room in women randomized to pre-procedure oral phenazopyridine versus those randomized to intravesical lidocaine instillation.
Being tested
Phenazopyridine, Lidocaine 2% Injectable Solution

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PhenazopyridineDrug

    200mg PO Phenazopyridine taken 1-2 hours prior to the Botox® injection procedure

  • Lidocaine 2% Injectable SolutionDrug

    30mL 2% lidocaine instilled into the bladder lumen 20 via a urinary catheter 20 minutes prior to the Botox® injection procedure

Study groups in NCT03755089
Study groupRoleWhat they receive
Oral PhenazopyridineActive comparatorPatients randomized to the oral phenzopyridine arm will receive 200mg phenazopyridine to take by mouth 1-2 hours before their scheduled procedure.
Receives: Drug: Phenazopyridine
Intravesical LidocaineActive comparatorPatients randomized to the intravesical lidocaine arm will have the bladder back-filled with 30mL 2% lidocaine for the 20 minutes immediately preceding their procedure.
Receives: Drug: Lidocaine 2% Injectable Solution

What is being measured

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

  1. Analgesic Effect Measured with 100mm Visual Analog Scale

    The visual analog scale is a visual representation of pain severity rated from 0 (no pain) to 10 (worst pain imaginable). Therefore higher numbers represent more pain.The scale is represented visually using a 100 millimeter line and patients indicate their level of pain by pointing to a location on the line.

    Measured: Immediately post-procedure

Secondary outcomes (3)
  1. Overall Patient Satisfaction

    Overall patient satisfaction with the onabotulinumtoxinA injection procedure in women randomized to pre-procedure oral phenazopyridine versus those randomized to intravesical lidocaine instillation. Overall satisfaction will be measured with a single-item question utilizing a Likert scale with options ranging from very satisfied to very unsatisfied.

    Measured: Immediately post-procedure

  2. Ease of Procedure

    Physician's perception of ease of onabotulinumtoxinA injection procedure in women randomized to pre-procedure oral phenazopyridine versus those randomized to intravesical lidocaine instillation. This will be measured with a single item, five point Likert scale with options ranging from no difficulty to great difficulty.

    Measured: Immediately post-procedure

  3. Office Efficiency/Total Appointment Duration

    Total appointment time or total time spent in an office exam/procedure room in women randomized to pre-procedure oral phenazopyridine versus those randomized to intravesical lidocaine instillation. This will be measured by subtracting the appointment start time (time the patient was placed in the exam room) from the appointment end time (time of patient check-out).

    Measured: Immediately post-procedure

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Phenazopyridine and Lidocaine 2% Injectable Solution in people with Overactive Bladder Syndrome and Urge Incontinence, run by Women and Infants Hospital of Rhode Island at 1 site in United States.

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 5 inclusion and 16 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: status not confirmed, as of the sponsor's last update on 29 May 2020. 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 United States. 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?

Results are not available in the source record.

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

Contact Lauren E Stewart, MD (401-453-7560 ext. 48762, lstewart@wihri.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Analgesic Effect Measured with 100mm Visual Analog Scale (time frame: Immediately post-procedure). 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 NCT03755089, which also lists 1 linked publication.

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 29 May 2020.
