Trial Outcomes & Findings for Extended-Release Oxybutynin for the Treatment of Neurogenic Detrusor Overactivity (NCT NCT01796548)

NCT ID: NCT01796548

Last Updated: 2013-11-26

Results Overview

Maximal detrusor pressure represents the maximum pressure (peak amplitude) in the bladder during the first involuntary contraction of the bladder muscle. Detrusor pressure is the component of intravesical (in the bladder) pressure that is created by forces in the bladder wall (passive and active). It was estimated by subtracting abdominal pressure from intravesical pressure.

Measure
Oxybutynin
Participants received an initial dose of extended release (ER) oxybutynin chloride 10 milligram (mg) orally once daily, with an increment of 5 mg in the dosage, at an approximate 14-days interval to a maximum of 30 mg per day, until continence was achieved for the last 2 days of interval. Dose was decreased by 5 mg if there were intolerable side effects. The participants then continued the maintenance dose to 12-week treatment.

Population: Data for this outcome measure is not reported because the data was not collected and included in Case Report Form (CRF).

Detrusor leakpoint pressure is the level of pressure at which leakage of urine through the urethra occurs as the bladder fills without an increase in abdominal pressure. This was a measure of both strength of the urethral sphincters and compliance of the detrusor muscle.

Population: ITT population. Here "n" signifies participants who were evaluable for this measure at a particular time point. This study is early terminated and there were some missing data for total incontinence which lead to decrease value of total incontinence.

Episodes of total urinary incontinence were reported. Urinary incontinence is the complaint of any involuntary leakage of urine.

King Health Questionnaire assesses the physical and psycho-social aspects of the disease state. It is a self-administered questionnaire containing 21 questions scored in 9 domains (general health perception, incontinence impact, role limitations, physical limitations, social limitations, personal relationships, emotions, sleep or energy, and severity of urinary symptoms). All domains were assessed in a range: 0-100, where 0=best outcome/response and 100=worst outcome or response. Lower scores indicates better outcome or response.
