Outcome Measures
Primary Outcomes (1)
Number of Participants With Patch Test Responses
Allergen patch test sites were scored at Visit 3 (day 3-4) Visit 4 (day 7-8) Visit 5 (day 10-14) and Visit 6 Day 19-23). Determination of positive or negative test response for each allergen dose was assessed by the investigator following the final visit.
21 days post patch application
Secondary Outcomes (3)
Number of Subjects With Panel Adhesion
Day 2, visit 2 prior to panel removal
Tape Irritation
Visit 2 (day 2), visit 3 (day 3-4), visit 4 (day 7-8) visit 5 (day 10-14), visit 6 (day 19-23) with overall assessment by the Investigator following visit 6
Chip Irritation
Visit 2 (day 2), visit 3 (day 3-4), visit 4 (day 7-8) visit 5 (day 10-14), visit 6 (day 19-23) with overall assessment by the Investigator following visit 6
Study Arms (1)
Metal Allergen Epicutaneous Patch
EXPERIMENTAL8 allergens were tested. Not all subjects tested each allergen. Section reports number of subjects with positive responses to each allergen.
Interventions
48 hour application of metal allergen patch to diagnose contact dermatitis
