Study type | Interventional |
The purpose of this study is to determine whether women with overactive bladder (OAB) who receive direct instillation via a catheter of a Botulinum-A Toxin (Botox) with Dimethyl Sulfoxide (DMSO) solution experience significantly better improvement of their OAB symptoms when compared to a similar group of women with OAB who receive instillation of DMSO only.

Inclusion Criteria: - Female patient aged 18 years or older - No evidence of stress urinary incontinence on physical examination or urodynamics - Patients who have failed prior drug therapy for overactive bladder or detrusor hyperreflexia - Patients with symptoms and signs of OAB, detrusor hyperreflexia, urinary urgency, urinary urge incontinence. - Patient who is mentally competent with the ability to understand and comply with the requirements of the study - Patient who agrees to be available for the follow-up evaluations as required by the protocol - Patient who has given signed informed consent Exclusion Criteria: - Patient with Post-Void Residual Urine (PVRU) greater than 100 ml on repeated measures. (Patient with a single PVRU of >100 ml and followed by two consecutive PVRU measurements of <100 ml may be included in the study) - Patient with greater than vesicoureteral reflux grade 1, interstitial cystitis, genitourinary fistulae - Patient with pelvic organ prolapse stage III or IV, i.e. the most distal part of the prolapse protruding more than 1 cm beyond the hymen (>+1), at straining - Patient with un-investigated hematuria - Patient with lower tract genitourinary malignancies - Patient on current medication for stress urinary incontinence, such as alpha-adrenergic agonists or duloxetine, within three weeks prior to completing the baseline Bladder Diary (estrogen therapy on a stable dose for at least two months prior to study start is allowed) - Patient with ongoing complications of prior anti-incontinence surgery - Patient who is pregnant, lactating, or planning to become pregnant within the study period - Patient who has received pelvic radiation - Patient with any condition, which could lead to significant postoperative complications, including current infection and uncontrolled diabetes. - Patient who is morbidly obese (defined as BMI > 40 Kg/m2) - Patient who is bedridden, institutionalized or in such physical condition that she cannot move to the closest bathroom without assistance from another person - Patient with current or acute urinary tract infection, including cystitis or urethritis. (Patient with such infections should be treated with antibiotics, with subsequent urinalysis tests confirming the absence of such infection before study inclusion) - Patient with any condition that would preclude treatment due to contraindications and/or warnings in the study product's labeling - Patient on immunomodulatory therapy (suppressive or stimulatory) - Patient with known lidocaine hypersensitivity or hypersensitivity to any anesthetics to be used during the treatment session/surgical procedure - Patient with a concurrent use of another study product within two weeks prior to study start, or who concurrently participate in any other clinical study - Any disease that in the opinion of the Investigator would make the patient unsuitable for the study - Patient with a life expectancy of less than 12 months |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in Incontinence Quality of Life (I-QoL) Score | The I-QoL measures the effect of urinary incontinence on quality of life. It is divided into 3 subscales: 1) avoidance and limiting behavior, 2) psychosocial impact, and 3) social embarrassment. The I-QOL is comprised of 22 items, each with the response scale from '1= Extremely' to '5= Not at all'. A mean score for each subscale is calculated (averaging the scores for the items in each subscale) as well as a total score for all 22 items (sum of all subscale scores). The scores are then transformed to a 'Scale score' ranging from 0-100 points for ease of interpretation: Scale score = (sum of the items - lowest possible score)/possible raw score range X 100. Higher scores indicate less impact of incontinence on quality of life. |
Baseline, 1 month, 3 months | No |
Secondary | Change in Incontinence Impact Questionnaire Short Form (IIQ-7) | The IIQ-7 measures the effect of urinary incontinence on quality of life. It is comprised of 7 items, each with the response scale from "0=Not at all" to "3=Greatly." The scores can range from 0 to 21; a low score indicates less impact of incontinence on quality of life. | baseline, 1 month, 3 months | No |
Secondary | Change in International Consultation on Incontinence Questionnaire - Short Form Score (ICIQ-SF) | The ICIQ-SF provides a brief and robust measure to assess the impact of symptoms of incontinence on quality of life and outcome of treatment. The questionnaire has 4 items and the score can range from 0 to 21, with greater values indicating increased severity of symptoms and lower quality of life. | baseline, 1 month, 3 months | No |
Secondary | Change in Urogenital Distress Inventory (UDI-6) | The UDI-6 measures the effect of urinary incontinence on quality of life. It consists of 6 items, each with the response scale from "0=Not at all" to "3=Greatly." The scores can range from 0 to 18; a low score indicates less impact of incontinence on quality of life. | baseline, 1 month, 3 months | No |
Secondary | Number of Participants With Decrease in Blaivas-Groutz Anti-Incontinence Score at 1 Month and 3 Months | The Blaivas-Groutz Anti-incontinence scale was used as a measure of urinary incontinence. This scale combines information on the number of incontinent episodes in a 24-hour period, 24-hour pad weights, and a qualitative rating by the patient into a single score ranging from 0 to 6. this score is then used to categorize incontinence as none (0), mild (1-2), moderate (3-4), or severe (5-6). | baseline, 1 month, 3 months | No |
Secondary | Number of Participants With a Decrease in Urinary Urgency at 1 Month and 3 Months | Urinary urgency was measured by the Indevus Urgency Severity Scale (IUSS). The IUSS asks patients to assess the severity of 'urgency' at each void. The scale employs the following wording: "Degree of urgency is meant to describe your urge to urinate. Sometimes you may feel a very strong urge to urinate and at other times, you may feel a milder urge prior to the onset of a toilet void. Rate this feeling by circling 0, 1, 2, or 3, defined as: 0: NONE - no urgency, 1: MILD - awareness of urgency, but it is easily tolerated and you can continue with your usual activity or tasks, 2: MODERATE - enough urgency discomfort that it interferes with or shortens your usual activity or tasks, 3: SEVERE - extreme urgency discomfort that abruptly stops all activity or tasks." | Baseline, 1 month, 3 months | No |
