Investigating the Adhesion of New Adhesive to the Skin

Inclusion visit:

• Introduction to the study
• Inclusion in study
• Baseline information is obtained
• Instruct subject to pre-strip of abdominal skin

Test visits 1-25 (up to maximum 25 visits per subject. (1-3 days after pre-stripping the abdominal skin):

• Baseline measurements are conducted on both sides of the stomach (TEWL, hydration, erythema, pH - 3 repeated measurements under each adhesive strip area (upper, middle and bottom of adhesive strip)
• Potential wetting of skin - shower/bicycle exercise (max 60 minutes) and after-wetting baseline measurements are conducted (TEWL, hydration, erythema, pH - 3 times/strips (upper, middle and bottom of adhesive strip))
• Adhesive strips are weighted and applied
• Potential shower/bicycle exercise (max 60 minutes)
• Adhesive strips are removed at pre-defined timeslots (peel force measured)
• Discomfort when strip was peeled of is evaluated by subject (VAS)
• Measurements are conducted (TEWL, hydration, erythema, pH - 3 times/strips (upper, middle and bottom of adhesive strip))
• Acclimatization ½
• Measurements are conducted (TEWL, hydration, erythema, pH - 3 times/strips (upper, middle and bottom of adhesive strip))
• Adhesive strips are weighed
• Photo of adhesive strips

The subjects can be asked to apply and change strips every 24 hours between two test visits but for a maximum of 10 days between two visits. The strips should be applied at the same place every time.
