Investigation of a New Stoma Product for People With a Stoma

Coloplast A/S79 enrolled

Overview

The CP288 study is an investigation of a non-Conformité Européene marked stoma product which will be conducted in the UK, Italy, Netherlands, Germany, and Norway. The study will enroll up to 100 subjects. The study is a randomized, open-label, comparative study.

Enrolled participant with an ileostomy or colostomy with liquid output were randomized to test either the non-Conformité Européene marked investigational product or one of the five comparators Conformité Européene marked products first and then will be crossed over to receive the opposite intervention. The participant will first be included in an information and inclusion visit (V0) and after signing all consent forms will complete three test visits (V1, V2, and V3). Each participant will be enrolled for 2 × 42±3 days in total for the entire investigation, thus for a maximum of 90 days. The study is a randomised, controlled, open-label, comparative, cross-over, multicentre investigation with two test periods. The study was conducted in four different countries (UK, Germany, Italy, and Norway) with a total of six sites participating. The study is now complete.

Outcomes

Primary Outcomes

Max Itching Within a Week at Steady State

Participant were asked to rate their itching around the ostomy on a scale of 0-10 with 0= no itch ad 10= worst possible peristomal skin itch. The primary outcome measure was done on the Intended to Treat population. Steady state period of the treatment period began after three weeks of product use.

Time frame: Within a week at steady state

Secondary Outcomes

Percentage of Participants With Varying Frequency of Itching Skin in the Past 14 Days by End of Treatment

Participants were asked how often they had experienced itchy skin around their ostomy in the past 14 days by the end of treatment. The data was distributed into five categories: "None of the time", "A little of the time", Some of the time", A lot of the time", and "All of the time". The results are shown as the percentages of answers for that category out of a total of a 100% (comprising the total of all answers from all the categories). When adding the number for each of the five categories it sums up to 100. So the results are shown as "how many percentages are the answers from one category out of a total of 100% (all the answers)?".

Time frame: past 14 days by end of treatment

Steady state period of the treatment period began after three weeks of product use.

Time frame: Within one week at steady state

Discoloration Area (cm^2) Per Baseplate Change at Steady State

Participant were asked to take photos of their peristomal skin at each baseplate change. The discoloration area of the peristomal skin was determined using an algorithm. The algorithm estimated the area of the discolored skin (divided into three different zones). Steady state period of the treatment period began after three weeks of product use.

Time frame: 3 weeks

Intensity of Discolorated Area Scored Per Baseplate Change at Steady State After Three Weeks of Product Use

Photos of the peristomal skin was taken at each baseplate change. The intensity was determined with an overlay to the artificial intelligence algorithm. The overlay divided the area into ten different intensity intervals: "Intensity interval 1"=0-10 …., "Intensity interval 10"=91-100% redness. The score was then calculated as follows: 1\*(Interval 1 measurement)..+ 10\*(Interval 10 measurement). Thus, if the area was within the first interval (0-10% redness) it was multiplied with 1 or within Interval 10 it was multiplied with 10, resulting in a intensity score for the total area. If there is no discoloration the score is 0, and there is no theoretical maximum. A large score equals a high intensity on the skin. In the description of the endpoint (appendix. 1 in CIP), it was to be determined in the inner and outer zone per baseplate change at steady state. However, the algorithm only estimated a total intensity score; thus, the intensity will not be reported per inner and outer zone.

Time frame: 3 weeks

Total Discoloration, Erosion, and Tissue Overgrowth (DET) Score by End of Treatment at Steady State

Participant were asked to take photos close to the stoma, which was then assessed by a sponsor or health care professionals. They determined the discoloration, erosion, and tissue overgrowth domain by scoring the area (0-3, with 3 being a large area affected), and severity (1-2, with 2 being the highest severity) affected by each domain. Each three domains contributes to the calculation of the total Discoloration, Erosion and Tissue overgrowth score (DET) going from a scale of 0 to 15 ("Normal skin" (DET=0), "Mild" (DET=2- 3), "Moderate" (DET=4- 6), and "Severe" (7-15)). Steady state period of the treatment period began after three weeks of product use.

Time frame: 3 weeks

Discoloration Item Score by End of Treatment at Steady State

Participant were asked to take photos close to the stoma, which was then assessed by a sponsor or health care professionals. Discoloration is a part of the discoloration, erosion, and tissue overgrowth (DET) score where all domains are assess to give a total DET score, with a min of 0 and max of 15. The discoloration domain was scored by area (0-3, with 3 being a large area affected), and severity (1-2, with 2 being the highest severity) affected and the scores were added together for a total discoloration score (with the max total score being 5). The area is assessed first and if this is 0 then the score for discoloration is 0, meaning the severity is not assessed. This means that the maximum score possible is 5 and the lowest score possible is 0 and the higher the score the more discolored skin. Steady state period of the treatment period began after three weeks of product use

Time frame: 3 weeks

Erosion Item Score by End of Treatment at Steady State

Participant were asked to take photos close to the stoma, which was then assessed by a sponsor or health care professionals. Erosion is a part of the discoloration, erosion, and tissue overgrowth (DET) score where all domains are assess to give a total DET score, with a min of 0 and max of 15.The erosion domain was determined by scoring the area (0-3, with 3 being a large area affected), and severity (1-2, with 2 being the highest severity) affected and then adding the scores together for a total score (with the max total score being 5). The area is assessed first and if this is 0 then the score for erosion is 0, meaning the severity is not assessed. This means that the maximum score possible is 5 and the lowest score possible is 0 and the higher the score the more eroded skin. Steady state period of the treatment period began after three weeks of product use.

Time frame: 3 weeks

Tissue Overgrowth Item Score by End of Treatment at Steady State

Participant were asked to take photos close to the stoma, which was then assessed by a sponsor or health care professionals. Tissue overgrowth is a part of the discoloration, erosion, and tissue overgrowth (DET) score where all domains are assess to give a total DET score, with a min of 0 and max of 15. The Tissue Overgrowth domain was assessed by scoring the area (0-3, with 3 being a large area affected), and severity (1-2, with 2 being the highest severity) affected and then adding the scores together for a total score (with the max total score being 5). The area is assessed first and if this is 0 then the score for tissue overgrowth is 0, meaning the severity is not assessed. This means that the maximum score possible is 5 and the lowest score possible is 0 and the higher the score the more tissue overgrowth. Steady state period of the treatment period began after three weeks of product use.
