This was a multi-center, 14-day clinical use study with a 7-day regression period, being conducted to assess the changes in the skin microbiome with two moisturizers in female and male subjects 16-50 years of age with mild to moderate eczema that experienced a recent itch flare up.
In this study, subjects were divided into two groups, one group was supplied with a test product containing an over-the-counter (OTC) drug monographed ingredient for treatment of eczema. The other group was supplied with a cosmetic test product which is a standard dry skin daily moisturizer. Both groups were also provided with a cosmetic test cleanser to use in place of their normal cleanser. Subjects used the products for 14 days, followed by a 7-day regression period (no product use).
Subjects were assessed at Baseline and at Day 1, Day 3, Day 7, and Day 14 of product use. They were assessed again 7 days after stopping product use. Only the group provided with the test product containing the monograph ingredient for treatment of eczema were assessed for eczema endpoints after the Baseline visit.

| OTC Eczema Moisturizer Regimen | Drug | Subjects were assigned to use an OTC, oatmeal-containing eczema therapy moisturizing cream twice daily on their face and entire body for the 14-day treatment period of the study, in place of any other moisturizers/emollients. Subjects were also provided with a mild cleanser to use in place of their normal body wash and/or soap (same cleanser as used by Group B) per their usual cleansing routine.

Subjects were randomly assigned to two groups. One group was supplied with a test product containing an OTC drug monographed ingredient for treatment of eczema and the other group was supplied with a cosmetic test product which is a standard dry skin daily moisturizer. Both groups were also provided with a cosmetic test cleanser to use in place of their normal cleanser. There was a 7-day regression period following the 14 days of product use.

| Eczema Area Severity Index (EASI) - Change - Baseline to Day 14 | Change from baseline in total EASI score at Day 14. Group A only. The EASI scoring system provides a score that reflects the severity of clinical signs of eczema based on the percentage of affected area in each of 4 body regions - the head/neck, trunk, upper extremities, and lower extremities. Each body region is scored for 4 parameters: erythema, edema, excoriations, and lichenification on a 0 (none) to 3 (severe) scale. The score for these parameters is summed and then multiplied by a constant that reflects the relative body area of that body region (head/neck = 0.10; trunk = 0.30; upper extremities = 0.20, lower extremities = 0.40). The total EASI score is calculated as a sum of the scores for the 4 individual body regions. The total possible score ranges from 0 (no eczema anywhere on the body) to 72 (severest eczema symptoms on all body areas). | 2 weeks |
