Reduction in Number of Botox Injections for Urgency Urinary Incontinence
What this study is about
The overall objective of this study is to determine if a reduced injection site protocol (5 injection sites) using an equivalent amount of Botox provides comparable relief of Urgency Urinary Incontinence (UUI) symptoms compared to the standard injection site protocol (15-20 injection sites).
View original scientific description
The overall objective of this study is to determine if a reduced injection site protocol (5 injection sites) using an equivalent amount of Botox provides comparable relief of Urgency Urinary Incontinence (UUI) symptoms compared to the standard injection site protocol (15-20 injection sites). Our central hypothesis is that the 5-site injection protocol is non-inferior in terms of relief of UUI symptoms compared to the standard injection site protocol, measured by a non-inferior reduction in the number of UUI episodes per day.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Females at least 21 years of age
- English speaking
- Five or more urge urinary incontinence episodes on a three-day voiding diary. Urge incontinence episodes will be determined based on voiding diary and subject indication of coincident urge symptoms, allowing for self-characterization of incontinence type
- Urge predominant (urge \>50% of total incontinent episodes) urinary incontinence based on self-reported characterization of incontinent episodes on diary
- Patient or caregiver willing to perform clean intermittent catheterization, or patient willing to have indwelling Foley catheter in the event this would be required
- Request for treatment for urgency urinary incontinence. The patient may have tried other pharmacologic treatments for urge incontinence, such as antispasmodic agents or non-pharmacologic treatments, such as supervised behavioral therapy, supervised physical therapy, unsupervised physical therapy, supervised biofeedback, and transvaginal electrical stimulation.
- Subject has undergone 3-week washout period if subject were on anticholinergic therapy prior to enrollment
- Subject is able to complete all study related items and interviews
- Willingness and ability to comply with scheduled visits and study procedures.
Exclusion criteria
- Current symptomatic urinary tract infection that has not resolved prior to randomization.
- Baseline need for intermittent self-catheterization
- PVR (Post void residual) \>150 mL on 2 occasions with void(s) of greater than 150 mL
- Surgical treatment for stress incontinence (sling, Burch or urethral injection) or pelvic organ prolapse recommended or planned at enrollment by study investigator(s).
- Any prior intra-detrusor botulinum toxin A injections
- Previous or currently implanted neuromodulation (sacral or tibial).
- Surgically altered detrusor muscle, such as augmentation cystoplasty.
- Known allergy to botulinum toxin A.
- Women with known neurologic disease believed to potentially affect urinary function (history of stroke, Parkinson's disease, multiple sclerosis, spinal cord injuries, myasthenia gravis, Charcot-Marie-Tooth disease).
- Known allergy to lidocaine.
- Currently pregnant or lactating patients or patients planning pregnancy within the next year.
- Sexually active premenopausal women with a uterus who have either not had a tubal ligation or are not on a medically approved form of contraception for at least 3 months prior to and throughout the duration of the study.
- Cystoscopic findings that preclude injection, in the opinion of the investigator.
- Current or prior bladder malignancy.
- Inability to understand diary instructions and complete 3-day voiding diary.
- Subject has been previously diagnosed with interstitial cystitis or chronic pelvic pain syndrome.
- Subjects with hematuria who have not undergone a clinically appropriate evaluation.
- Serum creatinine level greater than twice the upper limit of normal within the previous year.
- Two or more hospitalizations for medical conditions in the previous years
- Plans to move out of area in the next 6 months
Where
- Charlottesville, Virginia
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
