Clinical Trial Summary

The purpose of this randomized, open-label, active-control trial is to compare the effectiveness of intra-detrusor botulinum toxin A (Botox A®, Allergan) versus sacral neuromodulation (InterStim®, Medtronic) for the treatment of refractory urge urinary incontinence. In addition, the study will evaluate select technical attributes of the interventions as well as the effect of these two interventions on other lower urinary tract and pelvic floor symptoms.

Hypothesis: InterStim® therapy will result in a greater reduction in daily urge urinary incontinence episodes over the 6-month follow-up period as compared to Botox A® injection.

A supplemental study investigates whether biological markers including those related to inflammation and connective tissue remodeling change following treatments with Botox A® and Interstim®.

Description:

Primary Aim:

To compare the change from baseline in the number of urge urinary incontinence episodes (UUIE) over 6 the six month follow-up period in women randomized to sacral neuromodulation (InterStim®) therapy, versus those randomized to intra-detrusor injection with 200 units of botulinum toxin A (Botox A®).

Secondary Aims:

• Long Term Efficacy: To compare the long-term (12 and 24 month) efficacy outcomes in women randomized to sacral neuromodulation(InterStim®) therapy, versus those randomized to intra-detrusor injection with 200 units of botulinum toxin A (Botox A®). Secondary efficacy outcomes, collected at 12 and 24 months as well as 6 months,include adequate control of their urge urinary incontinence, change in bothersome symptoms of urinary urge incontinence (UUI), severity of urge incontinence, urinary frequency, nocturia, subject satisfaction with therapy, quality of life measures and bowel and sexual function.

• Cost Effectiveness: To compare utilization of medical resources for cost effectiveness analysis and cost-utility between treatment groups.

• Treatment Safety and Burden: To assess safety profile and treatment burden of both interventions by comparing adverse event incidence between treatment arms, and also by obtaining estimates of incidence of treatment-specific safety and burden outcomes. Safety and burden outcomes for Botox A® injections include receipt of additional injections and intermittent catheterization due to voiding dysfunction/partial urinary retention. Safety and burden outcomes for InterStim® device include infection, pain, lead migration, reprogramming (and reasons for) and surgical revision (and reasons for).

Intervention

Device:
• InterStim® device
Eligible subjects will complete baseline assessments, be randomized and scheduled for first stage lead placement (FSLP) InterStim®. The criterion for an initial clinical response to InterStim® therapy will be defined as a =50% improvement in the mean number of UUIE/day on a minimum 3 day bladder diary, completed during the 7-14 days following the first stage lead placement (FSLP). Subjects with a = 50% improvement mean number of UUIE/day will be eligible to proceed with implantation of the implantable pulse generator (IPG). Subjects will then be followed monthly to determine the response to therapy.

Drug:
• Botox® injection
Eligible subjects will complete baseline assessments, be randomized and scheduled for Botox A® injection visit. Subjects who received a Botox A® injection will be assessed for a clinical response, at 1 month from injection, using the same clinical criterion (=50% improvement in the mean number of UUIE/day on a 3 day bladder diary completed prior to the 1 month visit). Those subjects that experience a clinical response, at one month, will be eligible for a repeat Botox A® injection after 6 months, if they experience degradation of clinical effect, using the PGSC.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Urge Urinary Incontinence (UUI) Episodes	The primary outcome is the change from baseline in mean number of UUI episodes over the first 6-month visit period (1, 2, 3, 4, 5 and 6 month assessments); and is measured using 3-day bladder diaries administered monthly for the first 6 month visit period.	6 Months
Secondary	Number of Participants With Improvement of Bladder Function and Urinary Leakage	Proportion of subjects who report adequate improvement of their bladder function and urinary leakage with the Patient Global Impression of Improvement Questionnaire (PGI-I) at 6 months. Adequate improvement is defined as a rating of 1, 2, or 3 (better) on the patient-reported measure of perceived improvement with treatment on a scale of 1 (very much better) to 7 (very much worse).	6 Months
Secondary	Change in Overactive Bladder	Change in mean Overactive Bladder Questionnaire Short Form (OABq-SF) score throughout baseline to the first 6-month visit (1, 2, 3, 4, 5, and 6-month assessments). Values range from 0 to 100 with higher scores on the symptom scale indicating greater severity of symptoms and higher scores on the quality of life scale indicating a better quality of life.	6 Months
Secondary	Urinary Frequency and Nocturia	Change in mean number of urinary incontinence episodes (any type) and nocturia episodes from baseline over the first 6-month visit period (1, 2, 3, 4, 5, and 6-month assessments) as measured by the 3 day bladder diary.	6 Months
Secondary	Severity of Urge Incontinence Symptoms	Severity of urge incontinence symptoms at 6 month visit period as measured by the Sandvik questionnaire. The Sandvik score is a patient-reported measure of incontinence severity as assessed on a scale of slight (1-2), moderate (3-6), severe (8-9), very severe (12) to severe (10-12) using a standard scoring algorithm.	6 Months
Secondary	Treatment Satisfaction (OAB-SATq Treatment Satisfaction, Adverse Effects, Treatment Endorsement, and Convenience)	Treatment satisfaction as measured by the mean Overactive Bladder Satisfaction of Treatment Questionnaire (OAB-SATq) score at 6 months (6 month assessment). The OAB-SATq score ranges from 0 to 100 and includes 5 subscales: treatment satisfaction, side effects, treatment endorsement, convenience, and treatment preference, with higher scores reflecting better satisfaction.	6 months
Secondary	Treatment Satisfaction (OAB-SATq Treatment Preference)	Treatment preference as measured by the Overactive Bladder Satisfaction of Treatment Questionnaire (OAB-SATq) at 6 months (6 month assessment).OAB-SATq treatment preference is a binary outcome that is classified as yes if a participant answers either "Slight preference for the treatment I am receiving now" or "Definitely prefer the treatment I am receiving now" to the question "Do you prefer the treatment that you received since entering this study to the treatment you received before the study?"	6 Months
Secondary	Quality of Life (UDI-SF)	Change from baseline in quality of life measures over the first 6 month visit period (6 month assessment) as measured by the change in mean Urinary Distress Inventory Short Form (UDI-SF) score. The UDI-SF scale has a range from 0 to 100 with higher scores indicating greater distress.	6 Months
Secondary	Quality of Life (IIQ-SF)	Change from baseline in quality of life measures over the first 6 month visit period (6 month assessment) as measured by the change in the mean Incontinence Impact Questionnaire short form (IIQ-SF) score. The IIQ-SF scale has a range from 0 to 100 with higher scores indicating a worse quality of life.	6 Months
Secondary	Quality of Life (HUI-3)	Change from baseline in quality of life measures over the first 6 month visit period (6 month assessment) as measured by the Health Utility Index, Version 3 (HUI-3). The HUI 3 scale has a range from 0 to 1 with higher scores representing better health.	6 Months
