Residual Urine at 1st Flow Stop (HCP-led Catheterization) i.e., Total Catheterisation Volume Minus Volume at 1st Flow-stop, Both Derived From a Catheterisation Profile Primary · Immediately after the procedure/catheterization, at second and third clinic visit following 4 weeks of home catheterization

The residual urine at 1st flow-stop during catheterization (performed by a HCP) represents the volume of urine left in the bladder, the first time the urine stops running out of the catheter during bladder emptying. Hence, the residual volume at 1st flow-stop was calculated as the total volume post catheterisation minus the volume at 1st flow-stop, derived from a catheterisation profile which was connected to a time-logged weighing \[g\].

Number of Flow-stop Episodes (HCP-led Catheterization) Primary · Immediately after catheterisation, at second and third clinic visit following 4 weeks of home catheterization

Number of flow-stop episodes were determined as instances where the flow rate decreased to less than 0.8 mL/s for a period of at least two seconds. All episodes were detected by automatic thresholding, followed by manual inspection, where the intra-catheter pressure readings were used to support the assessment of a flow stop.

Number of Flow-stop Episodes (Self-led Catheterization) Secondary · Immediately after the procedure/catheterization, at second and third clinic visit following 4 weeks of home catheterization

Number of flow-stops were measured with a pressure sensor, which is an electronic device used for monitoring the hydrostatic pressure at the outlet of an intermittent urinary catheter during emptying. From a sensor curve, flow-stops were identified by two individually trained evaluators as a hydrostatic pressure peak coinciding with a urine flow-stop/ urine dripping (flowrate lower than 0,8 ml/sec). Results from both evaluators were compared and in case of discrepancy a discussion was performed to extenuate discrepancies and agree on a final interpretation of the curves.

Residual Urine at 1st Flow Stop (Self-led Catheterization) Secondary · Immediately after the procedure/catheterization, at second and third clinic visit following 4 weeks of home catheterization

The residual urine at 1st flow-stop during catheterization (performed by the participant self) represents the volume of urine left in the bladder, the first time the urine stops running out of the catheter during bladder emptying. Hence, the residual volume at 1st flow-stop was calculated as the total volume post catheterisation minus the volume at 1st flow-stop, derived from a catheterisation profile which was connected to a time-logged weighing \[g\].

Adverse events — posted to ClinicalTrials.gov

Time frame: The study consisted of four study visits in a clinic (V0-V3) and two 4-week test periods at home. Hence, the total study duration for the individual subject lasted approximately nine weeks.. Reporting threshold: 0%. Adverse-event reports describe events observed during the trial — not all are caused by the drug.

Sponsor's own description

A multi-centre, randomized, controlled crossover design. The total study duration for the individual subject was approximately 9 weeks. The study consisted of four study visits (V0-V3) and two 4-week test periods at home (T1 and T2). Visit 0 and 1 was performed on the same day if subjects allowed. One population included all enrolled subjects who took part in the two test periods in a home setting only (T1 and T2). This constituted the Full Analysis Set (FAS) 1 (N=73)where only endpoints related to dipstick hematuria, catheter perception and quality of life were assessed. A subset of subjects from the FAS1 also took part in two clinic visits (V2 and V3) where endpoints related to bladder emptying and discomfort were assessed. One visit took place in between the two test periods at home (V2) and the other visit took place after the last test period at home (V3) which was also the termination visit. This subset is termed the FAS 2 (N=49).
