What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 24 participants in total. It began in 2024-07-19 with a primary completion date of 2025-05.

Brief Summary

This study was designed to reflect the safety pharmacokinetics and preliminary efficacy of MG-K10 Humanized Monoclonal Antibody Injection in adolescent patients 12-18 weeks of age with moderate to severe atopic dermatitis, administered every 2 or 4 weeks for 8 weeks

(e.g., significant side effects or safety risks); Inadequate efficacy is defined as: \- At least 4 weeks of potent or 2 weeks of ultra-potent topical glucocorticosteroids or 4 weeks of topical calcitonin within 6 months prior to Screening.Inadequate treatment outcome is defined as or maintain a state of remission or low disease activity (equivalent to an IGA score of 0 \[=(equivalent to an IGA score of 0 \[= asymptomatic\] - 2 \[= mildly symptomatic\]);- Important side effects or safety risks are those that, as assessed by the investigator or the patient's treating physician, outweigh the potential therapeutic benefit.Important side effects or safety risks are those that, as assessed by the investigator or the patient's treating physician, outweigh the potential therapeutic benefit, including treatment intolerance Important side effect or safety risk means a side effect or risk that outweighs the potential therapeutic benefit, as assessed by the Investigator or the patient's treating physician, including treatment intolerance, allergic reaction, significant skin atrophy, and systemic reaction。 4.
