Using a Contact Dermatitis Model With Biologic Medications to Study Skin Inflammation
Skin Inflammation, Allergic Contact Dermatitis

About this trial
This is an interventional basic science trial for Skin Inflammation focused on measuring skin inflammation, allergic contact dermatitis
Eligibility Criteria
Inclusion Criteria:
- Healthy adult subjects over the age of 18 years with no skin diseases
- Patients with dermatologic conditions such as atopic dermatitis, history of localized non-melanoma, keratinocytic skin cancer
- Patients with previous clinical patch testing
- UMass Medical School students and employees are eligible to participate.
- Non-English-speaking individuals are also eligible with the assistance of an interpreter and an approved short form consent in the appropriate language.
Exclusion Criteria:
- Adults unable to give consent
- History of the following specific dermatologic conditions (which would be confounders due to their particular immunologic etiologies, specifically the TNFa and IL-17 pathways which oppose the Th2 pathway): pityriasis rubra pilaris and psoriasis
- Patients actively receiving whole body phototherapy
- Patients actively receiving systemic broad-spectrum immunosuppression (prednisone, mycophenolate mofetil, azathioprine, methotrexate)
- Any history of poor wound healing
- History of uncontrolled diabetes
- History of easily torn skin
- Any known cardiac arrhythmia or history of heart failure
- History of demyelinating disease
- History of liver disease or alcohol abuse
- History of melanoma
- Pregnant women
- Individuals who are high risk for tuberculosis including prisoners, immigrants from TB- endemic areas, or US-based travelers who have visited TB-endemic areas
- Individuals with a self-reported personal history of infection with latent or active tuberculosis, HIV, Hepatitis B, or Hepatitis C will not be included, because the type of immunotherapies that will be used in this study may interfere with these conditions.
- For similar reasons, we will not be including individuals with signs of current or active infection, self-reported personal history of recurrent infections, or conditions that compromise the immune system, such as patients with malignancy (except non- melanoma, keratinocytic skin cancers).

Baseline Contact Allergen
Contact Allergen with Immunomodulator Pre-Treatment
Individuals who will have allergic contact dermatitis induced via squaric acid dibutyl ester (SADBE) and/or known patch test allergens followed by skin and blood sampling. There is a protocol to sensitize individuals to SADBE if they have not previously been exposed to SADBE.
Individuals from Arm 1 (Baseline Contact Allergen) who have been exposed to SADBE and/or known patch test allergens followed by skin and blood sampling. These individuals will be pre-treated via administration of a single dose of 1 biologic from the following list: dupilumab, adalimumab, ustekinumab, guselkumab, canakinumab, sarilumab; or a single application of 1 topical steroid from the following list: betamethasone valerate, triamcinolone acetonide, fluticasone propionate. Allergic contact dermatitis will then be induced and the skin sampled.
