Purpose

The purpose of this study is to see whether Botox A (injected into the bladder muscle) can improve symptoms of urge incontinence that has not improved with usual medical treatments.

Primary Outcome Measures:

Time to recurrence of detrusor overactivity incontinence symptoms [ Time Frame: 6 months ] [ Designated as safety issue: No ]
To allow sufficient time for the onset of action of botulinum toxin A, the earliest outcome measurement was 60 days after injection. Failure was defined as a patient global impression of improvement (PGI-I) score of 4 or greater, the commencement of any new treatment at any time after the first injection or increased intensity of previously established treatment for DOI.

Secondary Outcome Measures:

Change in incontinence episode frequency by bladder diary [ Time Frame: At 12 mos after first injection., but no less than 1 mo after second injection ] [ Designated as safety issue: No ]
based on the 3-day bladder diary completed pre-intervention and at 4 weeks post injection. A successful within-subject outcome will be defined as >75% reduction in the frequency of urge incontinence episodes compared to the baseline frequency.
Incontinence-related and health-related quality of life [ Time Frame: At 12 mos after first injection, but no less than 1 mo after second injection. ] [ Designated as safety issue: No ]
measured by the Urinary Distress Inventory subscale of the PFDI/PFIQ, the PISQ, and SF-36 administered at 4 weeks after the initial injection and either prior to any re-treatment or at the completion of study participation, whichever is earlier.
Voiding dysfunction requiring catheterization [ Time Frame: throughout 12-month study ] [ Designated as safety issue: Yes ]

Arms	Assigned Interventions
Experimental: Botox A up to two injections of 200 Units of intra-detrusor Botulinum Toxin A , which must be separated by at least eight weeks and no more than 52 weeks	Drug: Botulinum Toxin A, bladder detrusor muscle injection 200 U provided as a total of 6 cc of the masked substance into approximately 15 to 20 different detrusor muscle sites under direct visualization. Injections will be spread out to equally cover the entire dome of the bladder, but spare the bladder trigone and ureteral orifices. Other Name: Botox
Placebo Comparator: Placebo up to two injections of inactive injection (carrier saline), which must be separated by at least eight weeks and no more than 52 weeks	Drug: Vehicle saline as placebo A total of 6 cc of the masked substance into approximately 15 to 20 different detrusor muscle sites under direct visualization. Injections will be spread out to equally cover the entire dome of the bladder, but spare the bladder trigone and ureteral orifices

Detailed Description:

Women who suffer with urge incontinence may not get relief with usual medical treatment (such as medications or behavioral techniques). We plan to enroll women with refractory urge incontinence in centers across the US. Study participants will undergo cystoscopy (telescope look into the bladder) and injection of either Botox A or placebo. If symptoms are not adequately relieved, subjects participants will receive a second injection that is Botox A. Participants are interviewed monthly by study personnel to determine symptoms and health status.
