Study Evaluating a New Ostomy Appliance With Regard to Leakage, Handling and Comfort

Phase 2

Completed

Conditions: Colostomy

Interventions: Device: SS
Device: SenSura

Registration Number: NCT01243294

Lead Sponsor: Coloplast A/S

Brief Summary: The objective of this investigation is to evaluate leakage, handling and comfort of a new ostomy appliance compared to SenSura.

Detailed Description: Peristomal skin problems are reported to have a negative impact on the quality of life of people with a stoma and cause one third of all visits to a stoma care nurse. Stoma effluent in contact with the peristomal skin (leakage) appears to predispose patients to peristomal skin problems.

To protect the skin against effluent, the appliance used for collection of stoma effluent should completely cover the peristomal skin close to the stoma. Coloplast has developed a new ostomy appliance to improve the feeling of security and increase comfort by the appliance characteristics.

The objective of this investigation is to evaluate leakage, handling and comfort of a new ostomy appliance compared to SenSura.

The study is a randomised controlled cross-over intervention study, where all study participants will test two test products (new ostomy appliance and SenSura). Each test period will last 10 ± 2 days and the subjects will follow their usual wear and change pattern. The participants will visit the study investigator at study start and at cross-over. Evaluation of the test products will occur via questionnaires the subjects fill in at home.

50 healthy subjects with a colostomy will be included in the study.

Primary Outcome Measures

Name	Time	Method
Leakage (Percent of All Base Plates With Leakage)	After each base plate change measured over a period of 10 +/- 2 days. Base plates are changed 1-6 times a day	Leakage is evaluated after each change of base plate on a 4-point scale from no leakage, leakage on the base plate, leakage soiling clothe and sudden leakage - the 3 last mentioned are all defined as leakage. No leakage is the preferred end point

Secondary Outcome Measures

Name	Time	Method
Adverse Events	During the investigation ~ 24 days per subject	Safety is evaluated by adverse events occuring continues while the subjects are testing the devices
Security (Subjects Own Assessment)	After each test period, i.e. after 10 (±2) days with one test product and after 10 (±2) days with the other test product	Results of participants who answered on own assessment of security on a 5 point scale ('very poor', 'poor', 'acceptable', 'good' and 'very good'). 'Good' and 'very good' are the preferred end points The 'very good' result are presented here. Unit of measure is: Percentage of participants answering 'very good'
Handling at Appliance (Subjects Own Assessment)	After each test period, i.e. after 10 (±2) days with one test product and after 10 (±2) days with the other test product	Handling at appliance where evaluated by subjects own assessment on a 5 point scale from very difficult to very easy. Results of participants who answered on own feeling of handling at appliance on a 5 point scale (very difficult, difficult, acceptable, easy, very easy). Easy and very easy are the preferred end points and it is the these results that are presented here. Unit of measure is: Percentage of participants answering 'very easy' and 'easy'
Comfort (Subjects Own Assessment)	After each test period, i.e. after 10 (±2) days with one test product and after 10 (±2) days with the other test product	Comfort where evaluated by subjects own assessment on a 5 point scale from very uncomfortable to very comfortable. Results of participants who answered on own assessment of comfort of wearing the product on a 5 point scale (very uncomfortable, uncomfortable, acceptable, comfortable, very comfortable). Comfortable and very comfortable are the preferred end points and it is these results that are presented here. Unit of measure is: Percentage of participants answering 'very comfortable' and 'comfortable'
Wear Time (Registered by Subject When Applying and Removing a Product)	After each base plate change measured over a period of 10 +/- 2 days. Base plates are changed 1-6 times a day	Wear time was calculated from the time the subjects applied their product (date, year, time) to the time they detached the product (date, year, time). Wear time was estimated in hours per subject per base plate and mean value was calculated.
