Clinical Trial to Assess the Effects of Topical Lotions on Changes in the Skin Microbiome and Associations With Itch

Johnson & Johnson Consumer Products Company Division of Johnson & Johnson Consumer Companies, Inc.91 enrolled

Overview

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.

Interventions

OTC Eczema Moisturizer RegimenDRUG

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. After the 14-day treatment period, subjects discontinued use of the moisturizer for the 7-day regression period.

Cosmetic Moisturizer RegimenOTHER

Subjects were assigned to use a non-fragranced, dry skin daily moisturizer 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 A) per their usual cleansing routine. After the 14-day treatment period, subjects discontinued use of the moisturizer for the 7-day regression period.

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).
