Brief summary
The study is to reflect the effectiveness and safety of MG-K10 humanized monoclonal antibody injection in patients with moderate to severe atopic dermatitis.administered every 4 weeks for 52 week
Detailed description
The study was a multicenter, randomized, double-blind, placebo-controlled Phase III study. Approximately 498 adults with moderate-to-severe AD who were not controlled by local therapy were scheduled to receive multiple subcutaneous injections (administered every 4 weeks for 52 weeks). The study was divided into screening period (1-5 weeks), double-blind treatment period (16 weeks), treatment maintenance period (36 weeks), and follow-up period (8 weeks).

Inclusion criteria
1. age 18-75 years (inclusive of 18 and 75 years), both sexes; 2. patients with AD diagnosed in accordance with the American Academy of Dermatology Consensus Criteria (2014), with a pre-screening diagnosis of AD or history of eczema for ≥1 year, and the following: * Eczema Area and Severity Index (EASI) score ≥16 at screening and baseline visit; * Investigator's Overall Assessment (IGA) ≥3 points at screening and baseline visit; * BSA ≥10% of area of AD involvement at screening and baseline visit * Weekly mean of peak daily itch NRS score ≥4 at randomization; 3. the patient had an inadequate treatment effect on topical medication or systemic therapy within 6 months prior to the screening visit, or the use of topical medication or systemic therapy was medically inappropriate 4. negative screening blood pregnancy test results in women of childbearing age;
Exclusion criteria
. 1. subjects with a current diagnosis of other active skin disease (e.g., psoriasis or lupus erythematosus) that may interfere with AD evaluation; 2. Patients with ocular disease that, in the judgment of the Investigator, makes enrollment in the study inappropriate, e.g., past history of atopic keratoconjunctivitis with corneal involvement; if the Investigator is unable to make a determination, a diagnosis will be made by an ophthalmologist; 3. those who plan to undergo major surgery during the study period, including inpatient surgery and daytime outpatient surgery; 4. Subjects with the following conditions: * Persons who have used a biologic agent within 10 weeks prior to randomization or have not exceeded 5 half-lives (whichever is longer); Targeted inhibitors (e.g., JAK inhibitors, etc.), systemic glucocorticoids, cyclosporine and other immunosuppressants (e.g., methotrexate, mycophenolate mofetil \[MMF\], and azathioprine, etc.), phosphodiesterase (PDE4) inhibitors, ultraviolet light therapy, and systemic herbal medicine for AD within 4 weeks prior to randomization; * Has received topical glucocorticosteroids, topical calcineurin phosphatase inhibitors, antibiotic compound cream, and topical herbal therapy for AD within 1 week before randomization; * Has received allergen-specific immunotherapy within 6 months prior to randomization; * Live/live attenuated vaccination within 3 months prior to randomization or planned for the duration of the study; * Participation in a clinical study of another drug in the 3 months or 5 half-lives, whichever is longer, prior to randomization or planning to participate in a clinical study of another drug during the study period; * Subjects with prior use of an interleukin 4 receptor alpha subunit (IL-4Rα) monoclonal antibody drug who, in the judgment of the investigator, have developed drug resistance or drug-related serious AE; * Previous participation in the MG-K10 clinical trial; 5. evidence of active tuberculosis, or previous evidence of active tuberculosis without appropriate documented treatment; chest X-ray (frontal and lateral) or CT, etc. within 3 months prior to/surrounding the screening period suggesting the presence of active tuberculosis infection; 6. women who are breastfeeding or pregnant, or who plan to become pregnant or breastfeed during the study;
