About this study

Official title: Is Less More? Does Decreasing OnabotulinumtoxinA Injection Sites in the Bladder Increase Patient Satisfaction While Maintaining Efficacy?

Patients with overactive bladder (OAB) will be randomly assigned (like a flip of a coin) to receive 100 units of onabotulinumtoxinA injected into the bladder at either 3 sites or 10 sites. Patient satisfaction and the effectiveness of the medication will be evaluated.

Read the detailed description

Overactive bladder (OAB) is a common condition which often has a negative impact on health related quality of life. Primary and secondary treatments include behavior modification, pelvic floor physical therapy, and OAB medications. OnabotulinumtoxinA (BTX) is a well-established third line therapy for refractory OAB.

BTX has transitioned over the years from a procedure conducted in the operating room to one that is commonly done in the clinic or physician office. While ten injection sites is commonly practiced, there has been continuing interest in reducing the number of injection sites to make the technique more tolerable and more efficient.

In this study, refractory OAB patients will be randomized to receive 100 units of BTX over 3 or 10 injection sites. The investigators hypothesize that decreasing the number of injection sites may improve patient tolerability and satisfaction with this office-based procedure and potentially reduce the rates of adverse events including hematuria and urinary tract infection.

What is being measured

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

  1. Number of Incontinence Episodes Per Day

    Participants will be asked to complete a 3-day voiding diary. On the diary participants will record the number of occurrences of voids over a 24 hour period for 3 consecutive days. Number of voids at 3 months are recorded.

    Measured: 3 months after the initial injection

Secondary outcomes (6)
  1. Degree of Bladder Symptom Bother

    Per the Overactive Bladder Questionnaire-Short Form (OABq-SF). This validated measure evaluates overactive bladder symptom severity and health related quality of life. For each question, participants will answer how bothered they are by their urinary symptoms from "not at all" (1), "a little bit" (2), "somewhat" (3), "quite a bit" (4), "a great deal" (5), and "a very great deal" (5). Each question will be scored. Scores range from 19-114. The higher the score the greater perceived degree of bladder symptom bother.

    Measured: 3 months after the initial injection

  2. Severity of Urine Leakage

    Per the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). This validated questionnaire provides a measure to assess the impact of symptoms of incontinence on quality of life and outcome of treatment. Question items include frequency of urinary incontinence, amount of leakage, overall impact of urinary incontinence, and a self-diagnostic item. Scoring is between 0-21 with greater values indicating increased severity.

    Measured: 3 months after the initial injection

  3. Change in Overactive Bladder Symptoms

    Per the Global Response Assessment (GRA). Participants will assess overall how their OAB symptoms/condition changed since starting the study. Participants will select, "Markedly worse" (1), "Moderately worse" (2), "Mildly worse" (3), "Same (unchanged)" (4), "Slightly improved" (5), "Moderately improved" (6), or "Markedly improved" (7). Scores are from 1-7 with a greater score indicating a greater improvement of symptoms. Numbers of participants reporting each assessment will be reported.

    Measured: 3 months after the initial injection

  4. Overall Patient Pain Tolerability With Treatment

    Per the Visual Analog Scale (VAS). Participants will record the amount of pain of performing the treatment on a Visual Analog Scale from 0 (no pain) to 10 (worst pain imaginable). Visual analog scores will be gathered at the end of the injection visit.

    Measured: After the initial injection

  5. Overall Voiding Symptoms at 3 Months

    Per the 3-day voiding diary. Participants will be asked to complete a 3-day voiding diary. On the diary participants will record the number of occurrences of voids, urge and stress incontinence episodes over a 24 hour period for 3 consecutive days.

    Measured: 3 months after the initial injection

  6. Safety of Bladder Injections

    Frequency and severity of study-related adverse events

    Measured: At study completion, 3 months after the initial injection

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing OnabotulinumtoxinA 100Unit Injection in people with Overactive Bladder and Overactive Bladder Syndrome, run by Corewell Health East 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 8 inclusion and 12 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: stopped early, as of the sponsor's last update on 10 Feb 2022. 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?

Yes. Results are posted in the registry (first posted 10 Feb 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Incontinence Episodes Per Day (time frame: 3 months after the initial injection). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 Feb 2022.
