A Study to Explore the Safety, Tolerability, Efficacy, and Pharmacokinetics of LT-002-158 Tablets in Chinese Adult Subjects With Atopic Dermatitis

April 9, 2025 updated by: Leadingtac Pharmaceutical (Shaoxing) Co., Ltd.

A Phase Ic/II Clinical Study to Explore the Safety, Tolerability, Efficacy, and Pharmacokinetics of Multiple Oral Doses of LT-002-158 Tablets in Chinese Adult Subjects With Atopic Dermatitis

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  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. History of important organ transplantation (such as heart, lung, kidney, liver) or hematopoietic stem cell/bone marrow transplantation.
  6. After inquiry, there is a history of lymphoproliferative diseases; Or currently suffering from malignant tumors or having a history of malignant tumors (excluding squamous cell carcinoma in situ of the skin, basal cell carcinoma, and cervical cancer in situ, which have achieved complete remission after radical treatment for more than 5 years without any signs of recurrence).
  7. A family history of sudden death or long QT syndrome, or subjects with a history of congenital or drug-induced long QT syndrome.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Incidence and severity of treatment emergent Adverse Events
Time Frame: up to 42 days
up to 42 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Area under the curve plasma concentration from time zero to last measurable concentration [AUC(0-last)]
Time Frame: up to 42 days
up to 42 days
Maximum observed plasma concentration at steady state (Cmax,ss)
Time Frame: up to 42 days
up to 42 days
