Metal Panel Patch Test
- Conditions
- Allergic contact dermatitis
- Registration Number
- 2023-507972-35-01
- Lead Sponsor
- Smarthealth Inc.
- Brief Summary
The objective of this study is to evaluate the diagnostic efficacy and safety of the investigational allergens and overall safety and performance of the investigational panel device constituent.
- Detailed Description
A single application of an investigational patch test panel containing 11 hydrogel metal allergens and a corresponding patch test panel containing 11 petrolatum metal allergens will be applied to the upper back of human subjects to test diagnostic efficacy and safety. Patch test panels will be removed after being worn for approximately 48 hours. Study will require 6 visits over the course of 21 days; patch application, patch removal and 4 patch test site evaluation visits at days 4, 7, 14 and 21.

c. Topical treatment with corticosteroids or other immunosuppressive agents on or near the test area 14 days prior to inclusion through the end of the subject’s participation in the study.
d. Systemic treatment with corticosteroids (equivalent to > 10 mg prednisone) or other immunosuppressive agents 14 days prior to inclusion through the end of the subject’s participation in the study. Inhaled treatments and steroidal nose or eye drops are permitted.
e. Treatment with ultraviolet (UV) light (including tanning) during the 3 weeks prior to inclusion through the end of the subject’s participation in the study.
f. Acute dermatitis outbreak or dermatitis on or near the test area on the back.
g. Known or suspected infection of the skin, joints or other site(s) associated with metal exposure
h. Condition such as, fibromyalgia, chronic fatigue, depression, cognitive impairment, flu-like symptoms, diarrhea and/or headache without at least one of the symptoms related to metal exposure listed in Section 6.6.
i. Condition such as, psoriasis, dermatitis herpetiformis, mycosis fungoides or cutaneous T-cell lymphoma that may confound the evaluation of allergic contact dermatitis.
