Human Repeat Insult Patch Test of Wound Dressings
|Skin Sensitization||Device: IV Clear™ Device: Tegaderm CHG™ Device: Silicone Vehicle Control Dressing||Phase 1|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
- Irritation [ Time Frame: Assessed at induction phase (evaluated before reapplication; 9 applications over 3 weeks, reapplied after every 48 or 72 hrs) and challenge phase (single 48-hr application of test article to naive sites and evaluation 30 mins, 24 and 48 hrs post-removal ]Irritation assessed at the induction phase will be scored on a Berger and Bowman Scale. Irritation assessed at the challenge phase will be scored on a defined scale measuring erythema reactions, ranging from no reaction to strong erythema.
- Adhesion [ Time Frame: Assessed at each 72 hour evaluation over three weeks, and once for a single 48-hour challenge application ]
Adhesion was scored as follows:
0 = no lift from skin (≥90% adherence)
- = some edges only lifting from skin (≥75% to ˂90% adherence)
- = less than half of the test article lifing (≥50% to ˂75% adherence)
- = more than half of the test article lifing but not detached (≥25% to ˂50% adherence)
- = test article detached (0% adherence)
- Pain upon removal [ Time Frame: Assessed by subjects at 72 hour evaluations over three weeks and a single 48-hour challenge application ]Any pain experienced during removal will be rated on a scale from 0 to 10, where 0 = no pain and 10 = worst possible pain.

|Experimental: IV Clear™||
Device: IV Clear™
Polyurethane film with a silicone adhesive dressing containing chlorhexidine and silver
|Active Comparator: Tegaderm CHG™||
Device: Tegaderm CHG™
Polyurethane film with a polyacrylate adhesive and a polyol hydrogel containing 2% w/w chlorhexidine gluconate
|Placebo Comparator: Control Vehicle Dressing||
