Trial Outcomes & Findings for An Investigation of Ostomy Devices (NCT NCT01514136)

NCT ID: NCT01514136

Last Updated: 2015-03-11

Results Overview

The degree of leakage under the baseplate was measured on a 24-point scale where 0 point was the best possible outcome with no leakage under the baseplate and 24-point was the worst possible outcome with leakage under the whole plate. The scale was developed by Coloplast A/S

Participant Flow

The subject were recruited through the Coloplast A/S user database in Denmark.

The investigation consisted of two periods: in the first period the newly developed concepts, Test A-D, were tested. Based on the results, four new concepts, Test A\*-D\*, were developed and tested. The test products were not randomised. The test order in first round was Test A - Test D and in second round it was Test A\*-Test D\*.

Test A
The investigation was set up with two different periods. In the first period the newly developed concepts, Test A-D, were tested. Based on the results, four new concepts were developed and tested, Test A\* - D\*. Therefore the participant flow is divided by the test products and not for each period. Test A was a newly developed concept by Coloplast A/S for the first round.
Test B
The investigation was set up with two different periods. In the first period the newly developed concepts, Test A-D, were tested. Based on the results, four new concepts were developed and tested, Test A\* - D\*. Therefore the participant flow is divided by the test products and not for each period.
