ABSTRACT
BACKGROUND: Atopic dermatitis (AD) is a recurrent, inflammatory, and chronic skin disease that influences over 200 million individuals around the world and is viewed as an important health problem due to its elevated prevalence, long course of disease, and heavy disease burden. WuSheZhiYang (WSZY) pills are composed of 11 Chinese herbs and have the effects of nourishing the blood, drying dampness, and relieving itching. In clinical practice, WSZY pills are recommended for itching skin diseases, but high-quality clinical trial evidence is still limited.
OBJECTIVE: In this study, we will implement a double-blind, randomized, placebo-controlled trial to evaluate the efficacy of WSZY pills for mild-to-moderate AD. We hypothesized that WSZY pills can effectively alleviate the disease condition of patients with mild-to-moderate AD.
METHODS: In this study, we will recruit 60 patients with mild-to-moderate in Shanghai Skin Diseases Hospital from December 2024 through December 2025. In this study, 60 male and female patients with AD aged 18 years to 65 years will be randomly assigned (2:1) to the treatment group (urea ointment and WSZY pills; n=40) or control group (urea ointment and placebo WSZY pills; n=20), and both groups will receive 4 weeks of treatment and 4 weeks of follow-up. The treatment group will receive 3 sessions of urea ointment and 7.5 g of WSZY pills each day for 4 weeks, and the control group will also receive 3 sessions of urea ointment and 7.5 g of placebo WSZY pills each day for 4 weeks. The primary indicator is the change in the objective Scoring Atopic Dermatitis (SCORAD) score between baseline and week 4. The secondary indicators include SCORAD at week 2 and week 8; Peak Pruritus Numerical Rating Scale (PP-NRS), Investigator’s Global Assessment (IGA), Patient-Oriented Eczema Measure (POEM), and Dermatology Life Quality Index (DLQI) at week 2, week 4, and week 8; and the proportion of participants receiving remedial treatment, amount of levocetirizine tablets used, and recurrence rate at week 8. In this study, we will analyze the full analysis set and per-protocol set using SAS software version 9.4, and a 2-tailed alpha level of .05 will be viewed as statistically significant.
RESULTS: The study received ethics permission in September 2024, and trial registration was completed in October 2024. Recruitment started in December 2024 and is expected to be completed by December 2025. As of June 2025, 30 participants with mild-to-moderate AD were enrolled. Data analysis will begin in January 2026. The main results of the trial are expected to be submitted for publication in peer-reviewed scientific journals in the summer of 2026.
CONCLUSIONS: This study will evaluate the efficacy of WSZY pills for AD and provide additional evidence, suggest new therapeutic options for patients, and reduce their disease burden.
