PRIMARY outcome

Timeframe: baseline and up to 6 weeks of treatment Last Observation Carried Forward (LOCF)

Population: Modified intention-to-treat (mITT): participants included in the safety sample (received at least one dose), randomized correctly according to the Urodynamic Adjudication Board (UDAB), having one valid baseline and one valid (UDAB) on treatment urodynamic measurement. The number is not identical to participants who "completed" the study.

Bladder volume was measure by means of urodynamic assessments (cystometry) for up to 6 weeks. Missing data were imputed with last observation carried forward (LOCF).

The OAB-q is a validated, self-administered questionnaire that quantifies bladder symptoms and quality of life. It comprises 33 items (6-point scale for each item). The total score ranges from 33 (minimum symptoms) to 198 (maximum symptoms). On each item, participants provide their rating over the past 4 weeks. Missing data were imputed by LOCF.
