Summary
The study aims to investigate two new non-invasive technologies for assessing skin properties to identify and validate a range of safety biomarkers that may be considered useful as primary outcome measures for evaluating the safety of topical treatments in atopic dermatitis. The method of assessing these biomarker technologies will be to determine whether twice daily treatment with crisaborole (2%) ointment, compared to betamethasone valerate (0.1%) cream, for up to 4 weeks, may cause skin structure or function changes, like skin atrophy, in patients with atopic dermatitis (AD).
Eligibility Criteria
Inclusion Criteria
- Volunteers with AD defined according to the UK working party diagnostic criteria
- Male or female aged 18-65 years old at baseline (Visit 1)
- Volunteer understands the purpose, modalities and potential risk of the trial
- Participants able to read and understand English
- Participants willing to sign the informed consent
Exclusion Criteria
- Participants with a known allergy/hypersensitivity to any of the excipients of the trial preparations.
- Participants with acne, suntan, birth marks, multiple nevi, tattoos, blemishes or dense body hair that obstruct the test areas.
- Investigator assessment of eczema severity at the treatment (anatomical) sites is almost clear or greater (score ≥1) based on the Investigators static global assessment scale at screening and baseline. At the start of the study the skin of the test sites (forearms) will therefore be clear (0) of the signs of eczema
- Participants with a condition that in the opinion of the investigator contradicts participation in the study.
- Pregnant female participants; breastfeeding female participants; and female participants of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for at least 28 days after the last dose of investigational product.
- Use of any topical product on the test areas within 7 days prior to Baseline/Day 1, including cosmetic moisturizers and sunscreen. Participants using any topical products on the test areas within 7 days at the screening visit will be eligible if they are willing and able to wash-out these products for 7 days in total and for the duration of the trial. Such participants will be potentially eligible at screening and will be confirmed as eligible if adequate washout is confirmed at visit 1. Use of moisturizers and/or sunscreen is permitted during the study to manage dry skin and sun exposure in areas surrounding but not on or overlapping the test areas.
- Participants who have used a tanning bed within 28 days of baseline (visit 1). Participants who have used a sunbed within 28 days at the screening visit will be eligible if they are willing and able to wash-out for 28 days in total and for the duration of the trial. Such participants will be potentially eligible at screening and will be confirmed as eligible if adequate washout is confirmed at visit 1.
- Participants who have used any medication that could interfere with the trial aim prior to the start of the study (baseline/visit 1). Participants using such medication at the screening visit will be eligible if they are willing and able to wash-out these treatments for the applicable washout period as defined by in section 8.8 'Prior and Concomitant Medication' and for the duration of the trial. Such participants will be potentially eligible at screening and will be confirmed as eligible if adequate washout is confirmed at visit 1.
- Participants currently participating in another interventional clinical trial.
- Volunteer is incapable of giving fully informed consent.
- Participants judged by the PI to be inappropriate for the trial.
