Atopic Dermatitis (AD)
Conditions
Brief summary
This study is an Ic/II phase clinical trial conducted in Chinese subjects with moderate to severe atopic dermatitis. The phase Ic study is a randomized, open label, parallel group design, mainly evaluating the safety and tolerability of LT-002-158 tablets in subjects with moderate to severe atopic dermatitis. The phase II study is a randomized, double-blind, placebo-controlled, parallel group design, with a single arm design for extended treatment, mainly exploring the efficacy of LT-002-158 tablets in the treatment of moderate to severe atopic dermatitis subjects.
Interventions
The subjects will orally administered LT-002-158 tablets once a day.

Inclusion criteria
1. When signing the informed consent form, the age range is 18 to 75 years old (including threshold), and there is no gender limit. 2. Body mass index (BMI) is between 17.5 and 40.0 kg/m2 (inclusive), with a weight of ≥ 45.0 kg. 3. Insufficient response or intolerance to topical corticosteroids (TCS) or topical calcineurin inhibitors (TCI) within the last 6 months of randomization; Insufficient response is defined as the failure to achieve and maintain remission or low disease activity (equivalent to vIGA 0=complete clearance to 2=mild) despite the use of a moderate to high efficacy TCS regimen (± TCI if applicable) for at least 28 days or the longest duration recommended in the drug prescription information (e.g. 14 days for super potent TCS), whichever is shorter. 4. Subjects must use topical moisturizers (moisturizers) daily for at least 7 consecutive days prior to the baseline visit. Participants should continue to use daily moisturizers during the study period. 5. Female and male participants with fertility and their partners had no fertility plans during the study period and within 6 months after the last dose, and agreed to take effective contraceptive measures. 6. Understand and voluntarily sign written informed consent; Willing and able to complete planned visits, treatments, examinations, and other procedures (such as dietary requirements, diary card recording, and collection) according to the requirements of the plan.
Exclusion criteria
1. Merge other skin diseases that may interfere with the study evaluation, such as psoriasis, tinea corporis, lupus erythematosus, etc. 2. Systemic anti infective therapy is required for active or chronic recurrent infections within the 4 weeks prior to the baseline visit. 3. Known or suspected to have a history of immune deficiency disease, other immune related diseases, invasive opportunistic infections or associated active tuberculosis. 4. History of severe or recurrent herpes virus infection, such as herpetic encephalitis, disseminated herpes, etc. 5.
