Eligibility

Inclusion Criteria:

• Age 18-65 (when signing informed consent), regardless of gender;

• Meets 2014 American Academy of Dermatology (AAD) criteria with diagnosis of atopic dermatitis (AD); In addition, history of AD prior to screening = 6 months; Eczema was previously diagnosed but met the 2014 AAD criteria and can still be enrolled.

1. total area of AD lesions= 10% BSA;

2. IGA =3 points;

3. EASI = 16 points;

• Baseline peak pruritus NRS =4 (The average peak pruritus intensity score in baseline peak pruritus NRS will be calculated based on the average of the peak pruritus intensity NRS score (daily score range 0-10) for each day during the 7 days prior to randomization. A minimum of 4 days out of 7 days of scoring is required to calculate the baseline average score. If the patient's reporting days are less than 4 days in the 7 days prior to the planned randomization date, randomization should be postponed until the requirements are met, but not beyond the maximum period of 14 days for screening);

• 6 months prior to the screening period, insufficient response to stable (=1 month) topical corticosteroids (TCS) or calcineurin inhibitors (TCI) (insufficient response defined as at least 28 days even if the daily regimen of moderate-high potency TCS (± topical TCI, if applicable) is at least 28 days, or to the maximum recommended course of treatment (eg, ultra-potent TCS - 14 days) in the product prescribing information (whichever is shorter), Failure to achieve or maintain disease remission or low disease activity (equivalent to IGA 0 [=none]-2 [=mild]). or patients who have received a record of systemic treatment (adequate dose, adequate course) of AD in the past 6 months are also considered to have insufficient response to topical drug therapy, and may be selected for trial after appropriate drug elution and approval by the sponsor);

• Before the first dose, subjects must have continuously used the emollient twice a day for at least 1 week and maintained throughout the trial (Note: the emollient is provided by the sponsor);

• Be able to read and understand, and be willing to sign informed consent forms;

• Computed Tomography (CT) of the chest shows active or occult tuberculosis or a history of contact with an open tuberculosis (TB) subject within the past 6 months. If the laboratory T cell spot test for tuberculosis infection test (or other tuberculosis diagnostic test) is positive, its activity is judged in combination with the medical history, clinical manifestations, etc., and the investigator determines whether it can be enrolled;

• Active hepatitis during the screening period, or positive for hepatitis B surface antigen (HBsAg), or positive for hepatitis B core antibody (HBcAb);

• History of human immunodeficiency virus (HIV) infection, or positive HIV serological results at screening, and positive antibodies to treponema pallidum during screening

• Positive for treponemal pallidum antibodies during screening

• Parasitic infection related to any of the following is excluded:

1. Routine inspection of worm eggs during the screening period;

2. History of parasitic infection within 6 months prior to the screening period, except for cured trichomoniasis;

• Pregnant or lactating women

• People who are alcoholic, drug addicts, and known drug dependents

• In the judgment of the investigator or sponsoring medical auditor, it is believed that there are any medical or psychiatric symptoms that put the subject at risk, interfere with participation in the study, or interfere with the interpretation of the results of the study.
