A Confirmatory, Multi-centre, Randomized, Open Label, Controlled Study Confirming Performance of a Single-use Intermittent Micro-holes Zone Catheter in a Population of Adult Male Intermittent Catheter Users.
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).
This investigation was a multi-centre, randomized, controlled crossover study including 73 male clean intermittent catheterization (CIC) users.
The study consisted of four study visits (V0-V3) and two 4-week test periods at home (T1 and T2). Visit 0 and 1 were performed on the same day if participants allowed. Visit 0 included the screening-, inclusion-, and randomization phase of participants and at visit 1, participants performed a self-catheterization with the device according to their respective randomization scheme. This was followed by a dipstick test for hematuria. This constituted the Full Analysis Set (FAS) 1, consisting of 73 participants.
In the two 4-week test periods (T1 and T2, respectively) the participants catheterized at home with the specified catheter according to their randomization scheme. Both 4-week periods started with a 2-week run-in period followed by a 2-week period during which a dipstick test for hematuria was performed daily.
For Visit 2 and 3, a sub-group of participants was invited for a clinical test visit during which participants were catheterized with the same device applied during the preceding home-test period. First a healthcare professional (HCP)-led catheterization was performed followed by a self-catheterization, and endpoints related to bladder emptying (residual urine and number of urinary flow-stop episodes) were measured. After each catheterization, any residual urine left in the bladder was measured with a bladder scanner and hematuria was assessed with a dip-stick test. After the self-catheterization process, subjects at clinic visit V2 and V3 completed a questionnaire related to discomfort.This constituted the Full Analysis Set (FAS) 2, consisting of 49 participants.
All participants completed a perception questionnaire and a HRQoL questionnaire associated with the catheter during the last two weeks of the home test period. For participants not part of clinic visits V2 and V3, a nurse assisted with the questionnaires after each home-test period during a remote home visit. Thereafter, all participants were introduced to the second device to be tested for the next home-test period.
After the second home-test period, the study was terminated with a test visit 3 (V3), either in the clinic (for the subset group, FAS2) or a home visit by the nurse (the FAS1 group).
