About this study

Official title: Standard Injections Versus Reduced Injections for Intravesical onabotulinumtoxinA for Treatment of Idiopathic and Neurogenic Overactive Bladder: a Randomized Trial

OnabotulinumtoxinA is an effective treatment for both idiopathic and neurogenic overactive bladder and was FDA approved for this indication in 2013. The standard technique for injecting onabotulinumtoxinA into the detrusor is mixing 100 units of onabotulinumtoxinA into 10mL of injectable normal saline and injecting 20 sites with 0.5mL in the posterior wall of hte bladder for idiopathic overactive bladder and mixing 200 units into 30mL and injecting 30 sites with 1mL for neurogenic overactive bladder. The purpose of this study is to compare the efficacy of a technique using a reduced number of injections with the same dosage of onabotulinumtoxinA to the standard technique. The hypothesis is that the reduced technique will not be inferior in terms of efficacy as the standard technique and that there will be a lower incidence of urinary tract infections and urinary retention requiring catheterization post-procedure.

Read the detailed description

Overactive bladder has a large economic burden within the United States and internationally. Patients are often non-compliant with first and second line treatments for overactive bladder or find that they do not significantly improve symptoms. Intradetrusor onabotulinumtoxinA injection has been showed in many studies to significantly improve overactive bladder symptoms and quality of life in patients and was approved by the FDA for the treatment of overactive bladder in 2013.

Intradetrusor onabotulinumtoxinA injections are often performed in the office setting under local anesthesia. The standard technique for injecting onabotulinumtoxinA into the detrusor is mixing 100 units of onabotulinumtoxinA into 10mL of injectable normal saline and injecting 20 sites with 0.5mL in the posterior wall of hte bladder for idiopathic overactive bladder and mixing 200 units into 30mL and injecting 30 sites with 1mL for neurogenic overactive bladder. Despite instillation of local anesthetic into the bladder prior to the procedure, many patients still find the procedure uncomfortable and may elect not to have treatment or to undergo treatment under sedation.

Some literature exists that suggests that a fewer number of injections with the same dosage of onabotulinumtoxinA still provides significant improvement in symptoms for patients with the potential for fewer adverse events, specifically urinary tract infection and urinary retention requiring catheterization.

The purpose of this study is to directly compare the standard techniqe for intradetrusor onabotulinumtoxinA injections to a reduced injection technique to compare efficacy and rates of adverse events between the two groups. The hypothesis is that the reduced injection technique will be non-inferior to the standard technique.

Participants in the study will be randomized to either the standard technique or the reduced technique at the time of their procedures, provided they meet the inclusion and exclusion criteria and provide written consent to participate. Efficacy will be measured using a series of validated patient questionnaires. Scores will be obtained at a baseline and then at two other time points post-procedure (4-12 weeks and 6-9 months). Rates of adverse outcomes, specifically urinary tract infection and urinary retention requiring catheterization, will also be obtained following the procedure.

Other than the randomization of patients into study and control groups and having patients complete a series of questionnaires, the care of patients undergoing intradetrusor onabotulinumtoxinA injections will follow the standard of care. All patients will be screened for urinary tract infection prior to the procedure and if they screen positive will have their procedures delayed until after they are treated. All patients will receive pre-procedure antibiotics according to the American Urological Association guidelines. All patients will be screened for urinary retention and for symptoms of urinary tract infection at their initial post-procedure follow-up at 4-12 weeks and treated accordingly if they develop either.

What is being measured

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

  1. Mean change from baseline in overactive bladder symptom severity and health related quality of life scores on the overactive bladder questionnaire short form

    The overactive bladder questionnaire short form is a validated questionnaire assessing both symptoms and quality of life related to overactive bladder. The survey has two subscales, a health related quality of life scale and a symptom severity scale. Each subscale is scored separately with a range of 0 to 100. For health related quality of life a score of 0 indicates worst quality of life and 100 indicating best quality of life. For symptom severity, the scores also range from 0 to 100 but with higher scores indicating greater symptom severity and lower scores less symptom severity.

    Measured: 4-12 weeks post-procedure

  2. Mean change from baseline in overactive bladder symptom severity and health related quality of life scores on the overactive bladder questionnaire short form

    The overactive bladder questionnaire short form is a validated questionnaire assessing both symptoms and quality of life related to overactive bladder. The survey has two subscales, a health related quality of life scale and a symptom severity scale. Each subscale is scored separately with a range of 0 to 100. For health related quality of life a score of 0 indicates worst quality of life and 100 indicating best quality of life. For symptom severity, the scores also range from 0 to 100 but with higher scores indicating greater symptom severity and lower scores less symptom severity.

    Measured: 6-9 months post-procedure

  3. Mean change from baseline in overactive bladder symptoms on the International Consultation on Incontinence Questionnaire short form

    The International Consultation on Incontinence Questionnaire short form is a validated questionnaire assessing symptoms of overactive bladder and effect on quality of life. The scores range from 0 to 21 with higher scores indicating worse symptom severity and effect on quality of life.

    Measured: 4-12 weeks post-procedure

  4. Mean change from baseline in overactive bladder symptoms on the International Consultation on Incontinence Questionnaire short form

    The International Consultation on Incontinence Questionnaire short form is a validated questionnaire assessing symptoms of overactive bladder and effect on quality of life. Scores range from 0 to 21 with higher scores indicating greater symptom severity.

    Measured: 6-9 months post-procedure

  5. Mean change from baseline in overactive bladder symptoms assessed with the Patient Global Impression of Severity and Improvement scores

    The Patient Global Impression of Severity and Patient Global Impression of Improvement scores are validated single question surveys that assess patients' impression of the severity of their illness prior to treatment intervention and the degree of improvement following treatment intervention. The Patient Global Impression of Severity is a 4 point Likert scale ranging from 1 to 4 with 1 being normal and 4 being severe symptoms (mild and moderate completing the range of scores). The Patient Global Impression of Improvement is a 7 point Likert scale with 1 being very much better and 7 being very much worse (much better, a little better, no change, a little worse, and much worse completing the range of scores).

    Measured: baseline, 4-12 weeks post-procedure and 6-9 months post-procedure

  6. Mean change from baseline in overactive bladder symptoms assessed with the Patient Global Impression of Severity and Improvement scores

    The Patient Global Impression of Severity and Patient Global Impression of Improvement scores are validated single question surveys that assess patients' impression of the severity of their illness prior to treatment intervention and the degree of improvement following treatment intervention. The Patient Global Impression of Severity is a 4 point Likert scale ranging from 1 to 4 with 1 being normal and 4 being severe symptoms (mild and moderate completing the range of scores). The Patient Global Impression of Improvement is a 7 point Likert scale with 1 being very much better and 7 being very much worse (much better, a little better, no change, a little worse, and much worse completing the range of scores).

    Measured: 4-12 weeks post-procedure

  7. Mean change from baseline in overactive bladder symptoms and incontinence episodes using patient reported pad counts and episodes of nocturia

    Number of pads used for urge incontinence and nocturia episodes are frequent metrics used for assessing efficacy of overactive bladder treatments

    Measured: 6-9 months post-procedure

Secondary outcomes (3)
  1. Incidence of urinary tract infection

    Urinary tract infection is a common complication from intradetrusor onabotulinumtoxinA treatment

    Measured: 1 day to 12 weeks post-procedure

  2. Incidence of urinary retention requiring intermittent catheterization

    Urinary retention is a common complication following intradetrusor onabotulinumtoxinA treatment

    Measured: 2-6 weeks post-procedure

  3. Mean change in pain from baseline following intradetrusor onabotulinumtoxinA injection using visual analog scale

    Visual Analog Scales are validated tools for assessing pain. The scale is scored from 0 to 10 with 0 being no pain and 10 being worst possible pain.

    Measured: immediately post-procedure
