E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial will be the treatment preference of subjects who will be asked at the end of the 2nd treatment period after both treatment phases. The preference will be checked for its plausibility in an end-of-period satisfaction rating (total of scores on 4 items of final list of questions: 6=very satisfied, 0= very dissatisfied). Treatment satisfaction will be assessed at the end of each period of the cross over. The total score on the satisfaction questionnaire of the two treatment periods will be compared to express preference. |

E.2.2 | Secondary objectives of the trial |
Assessment of cognitive abilities during treatment with orally administered oxybutynin verus transdermal applicated Oxybutynin Quality of life Reports of AE/SAE. Frequency of micturition Frequency of urinary incontinence episodes Severity of urinary incontinence episodes Urgency frequency Treatment satisfaction

E.5 End points |
E.5.1 | Primary end point(s) |
Primary end point is treatment preference of the subjects who will be asked at the end of the 2nd treatment period. The preference will be checked for its plausibility in an end-of-period satisfaction rating. Treatment satisfaction will be assessed at the end of each period of the cross over. The total score on the satisfaction questionnaire of the two treatment periods will be compared to express preference. |
