Investigation of New Intermittent Catheter Swelling Media in Healthy Volunteers

Clinical Study in Healthy Volunteers Evaluating the Performance and Handling of a Urinary Intermittent Catheter With a Newly Developed Swelling Media.

Investigation of novel swelling media for CE marked intermittent urinary catheters. The study was a randomized, single blinded, cross-over investigation comparing a novel swelling media with a comparator swelling media in 22 adult, healthy, male volunteers.

Study Overview

• Status: Completed
• Conditions: Catheter Site Discomfort; Catheter Site Pain
• Intervention / Treatment: Device: Novel swelling media; Device: Comparator swelling media

Detailed Description

The CP279 study investigated a novel swelling media for male intermittent urinary catheters. The study was conducted in Denmark and was a single-site, randomized, single blinded, cross-over investigation, testing inferiority of a novel catheter swelling media against a comparator swelling media in 22 adult, healthy, male volunteers.

Each participant was randomized to one of two treatment arms, using a randomization sequence of two (i.e., with two different random options for the order in which the participants tested the two swelling media). The study thus contained two test visits, for which the 22 participants tested the two different swelling media, respectively. There was 4-14 days between the test visits and all catheterizations were performed by trained nurses. Due to a visual difference between the products, it was only possible to blind the subjects.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Novel swelling media; Participants underwent catheterization with the SpeediCath standard male catheter containing the novel swelling media. The catheterization was performed by a trained nurse.	Device: Novel swelling media; Intermittent catheterization through the urethra draining the bladder, performed by a trained nurse.
Active Comparator: Comparator swelling media; Participants underwent catheterization with CE-marked SpeediCath® standard male containing the original swelling media. The catheterization was performed by a trained nurse.	Device: Comparator swelling media; Intermittent catheterization through the urethra draining the bladder, performed by a trained nurse.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Discomfort During Nurse Catheterization	Discomfort measured for the entire catheterization procedure (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after the procedure/catheterization, up to 5 min.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Insertion Discomfort During Nurse Catheterization	Discomfort measured for the entire catheterization procedure (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after the procedure/catheterization, up to 5 min.
Withdrawal Discomfort During Nurse Catheterization	Discomfort measured for the entire catheterization procedure (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after the procedure/catheterization, up to 5 min.
Urination Discomfort After Catheterization	Discomfort measured for the entire catheterization procedure (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after first normal void, up to 5 min.
Catheter Handling During Insertion	Nurse evaluation of how he/she experienced catheter insertion on a 5-point likert scale including the options: Very difficult, difficult, neither difficult nor easy, easy or very easy.	Immediately after the procedure/catheterization, up to 5 min.
Catheter Handling During Withdrawal	Nurse evaluation of how he/she experienced catheter withdrawal on a 5-point likert scale including the options: Very difficult, difficult, neither difficult nor easy, easy or very easy.	Immediately after the procedure/catheterization, up to 5 min.
Touch of Catheter Coating	Nurse evaluation of whether or not it was needed to touch the catheter coating during handling and/or catheterization (yes/no).	Immediately after the procedure/catheterization, up to 5 min.
Visual Blood During Catheterization	Nurse evaluation of if he/she experienced visual blood on either the catheter or in the urine during catheterization (yes/no).	Immediately after the procedure/catheterization, up to 5 min.
Microscopic Blood in Catheter-collected Urine	Dipstick analysis of hematuria (erythrocytes) after catheterization using a semi-quantitative color scale with five categories ranging from negative to 3+: Negative (-). 10 erythrocytes/μL (+/-). 25 erythrocytes/μL (1+). 80 erythrocytes/μL (2+). 200 erythrocytes/μL (3+). At least one fully positive response (i.e., either 1+, 2+ or 3+), the endpoint was considered positive and the outcome was analyzed as a binary response (positive/negative).	Immediately after the procedure/catheterization, up to 30 min.
