Clinical Trial Summary

People with intestinal stomas (especially an ileostomy) can have, despite development of better ostomy products, problems with leakage which influence their quality of life negatively.

To overcome this, Coloplast has developed a new supporting ostomy product, which has an adhesive sensor layer that should be place underneath the baseplate normally used by the subject.

Single arm design. Open-labelled Study duration: 21 days + 3 days.

Description:

Test product is a Digital Leakage Notification System. It consist of a sensor layer (worn beneath the baseplate), a transmitter attached to the sensor layer, a charger for charging of transmitter and an app, to be installed on a smartphone, which notifies the user of the status of their baseplate such as everything looks okay or there is a possible leakage.

Subjects are asked to use test product for 21 days. n=15 were using a phone with Android operating system and n=10 a phone with iOS operating system.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	System Performance Accuracy of Pictures	The primary endpoint is system performance accuracy: True Negative: No leakage observed on picture and no leakage detected by system; True Positive: Leakage observed in picture and leakage detected by system; False Negative: Leakage observed in picture, but no leakage detected by system; False Positive: No leakage observed in picture, but leakage detected by system	21 days
Secondary	Frequency of Leakage Onto Clothes Before and After Use of Test Product	Subjects are asked to recall numbers of leakage events outside baseplate (and/or onto clothes) the past 3 weeks (at baseline and follow-up). Subjects shall give a specific frequency.	At V1 (baseline) and V2 (follow-up, Day 21)
Secondary	Experience of Leakage Onto Clothes Compared to Only Using Usual Product	Subject own interpretation, Q: to which degree have you experienced leakage onto your clothes with test product?" (5-point scale: very low degree/not at all, low degree, some degree, high degree, very high degree).	V2 (follow-up, Day 21)
Secondary	Reliability of Notifications	Subjects are asked to rate, Q: To which degree did you find notifications from the app reliable and trustworthy (5-point scale; very low degree, low degree, some degree, high degree, very high degree)	V2 (follow-up, Day 21)
Secondary	Ability to Move With Test Product	Q: Compared to your usual product, how was your freedom to move with test product? Much better - better - Same - Worse - Much worse	V2 (follow-up, Day 21)
Secondary	Subjects Worry of Leakage Before and After Use of Test Product	Q: Think back on the last 3 weeks - to which degree have you worried about leakage? Very high degree - High degree - Some degree - Low degree - Very low degree/Not at all	At V1 (baseline) and V2 (follow-up, Day 21)
Secondary	Confidence to Avoid Full Leakage With Test Product Compared to Only Using Usual Product	Q: Compared to your usual product, did you feel confident that you could avoid leakage onto clothes? Yes -No	V2 (follow-up, Day 21)
Secondary	Confidence in Daily Life Compared to Only Using Usual Product	Q: Compared to your usual product, to which degree did the test product give you confidence in daily life? Much higher degree- Higher degree- Same degree - Lower degree- Much lower degree	V2 (follow-up, Day 21)
Secondary	Feeling of Control With Test Product Compared to Only Using Usual Product	Q: Compared to your usual product, did test product give you a feeling of leakage control? Yes, higher leakage control No, lower leakage control	V2 (follow-up, Day 21)
Secondary	Control of Leakage Progression With Test Product Compared to Only Using Usual Product	Q: Compared to your usual product, did the test product give you a feeling of control of leakage progression? Yes, higher control of leakage progression No, lower control of leakage progression	V2 (follow-up, Day 21)
