An Exploratory Study Investigating Human Skin Reaction to Output

Coloplast A/S22 enrolled

Overview

The primary purpose of the study is to investigate the impact that feces mixtures have on the peristomal skin when using a standard adhesive.

Six types of patches are tested: Patch 1: Standard adhesive with own feces Patch 2: Standard adhesive with own feces mixture Patch 3: Standard adhesive with simulated feces Patch 4: Standard adhesive with simulated feces mixture Patch 5: Standard adhesive with buffer (control) Patch 6: Standard adhesive with buffer feces mixture (control) Each subject is randomized to one of two arms testing three patches on the peristomal skin (patch 1, 3 and 5 or patch 2, 4 and 6). Furthermore, within each arm an attempt will be made to randomize each of the three patches on the peristomal skin to one of three locations surrounding the stoma (upper left, upper right, lower). On the healthy contralateral abdominal skin the subjects test all six patches. A run in period with 2 subjects (healthy volunteers) was conducted to clarify the length of the test period. They were exposed to 4 patches (patch 3-6) on healthy abdominal skin which was removed at 2 different time slots. Based on the results the test period was established

Primary Outcomes

Trans Epidermal Water Loss After Test of Patches.

Trans Epidermal Water Loss is a standardized non-invasive method for describing the barrier function of the skin. Damage to the skin surface (stratum corneum) will lower the barrier of the skin and thereby increase water loss. This can be used as a measure for the damaging effect of the adhesives to the skin. Trans Epidermal Water Loss is measured by applying a probe to the skin surface and is assessed nine times for each patch after applying the patch: three repeated measurements of the skin covered by the center of the patch (Center), as well as three repeated measurements of the skin covered by the adhesive (Under adhesive).

Time frame: Approximately 7-10 hours
