Inclusion criteria
Inclusion criteria: 1. Subjects =7 to <12 years of age or =2 to <7 years of age at the screening visit. Note: Subjects aged 2 to 6 years can be enrolled only after the IA and the IDMC has assessed interim safety data from Cohort 1 (age 7 to 11 years) and provided recommendations to the Sponsor, who will then determine the eligibility of this age group for enrollment in the study and confirm the dose. The Sponsor will send a written communication to the sites confirming that the study is open for enrollment of Cohort 2 (age 2 to 6 years). This cohort must not be enrolled in the study until such communication is received. 2. Chronic AD that has been documented for at least 6 months for subjects aged 2-6 years and at least 1 year for subjects aged 7-11 years before the screening visit and confirmed according to the American Academy of Dermatology Consensus Criteria (Appendix 1) at the time of the screening visit. 3. Eczema Area and Severity Index (EASI) score =16 at both screening and baseline visits. 4. Investigator’s Global Assessment (IGA) score =3 (based on the IGA scale ranging from 0 to 4, in which 3 is moderate and 4 is severe) at both screening and baseline visits. 5. AD involvement =10% of Body Surface Area (BSA) at both screening and baseline visits. 6. Peak (maximum) Pruritus Numeric Rating Scale (PP NRS) score of at least 4.0 at both screening and baseline visits: • Screening PP NRS score will be determined by a single PP NRS assessment (score ranging from 0 to 10) for the 24-hour period immediately preceding the screening visit. • Baseline PP NRS score will be determined based on the average of daily PP NRS scores (score ranging from 0 to 10) during the 7 days immediately preceding baseline (rounding not permitted). A minimum of 4 daily scores out of the 7 days immediately preceding baseline is required for this calculation. 7. Documented history by a physician and/or investigator (within 6 months before the screening visit) of inadequate response to existing topical medication or use of systemic therapies for control of the disease. 8. Agree to apply a moisturizer throughout the study from the screening visit daily, and liberally as needed; agree to apply an authorized TCS, with or without TCI, from the screening visit and throughout the study as determined appropriate by the investigator. 9. Any female of childbearing potential (i.e., a subject who has started menstruating) who is, in the opinion of the investigator, sexually active and at risk for pregnancy must be willing and able either to be strictly abstinent or to use an adequate and approved method of contraception throughout the study and for 12 weeks after the last study drug injection. Adequate and approved methods of contraception applicable for the subject and/or her partner are defined below: • true abstinence, when in line with the preferred and usual lifestyle of the subject (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.) • combination of male condom with cap, diaphragm, or sponge with spermicide (double barrier methods) Note: “Double barrier methods” refers to simultaneous use of a physical barrier by each partner. Use of a single barrier method (e.g. condom) together with a spermicide is not acceptable. • oral hormonal contraception 10. Subject and caregiver willing and able to comply with all of the time commitments and procedural requirements of the clinical trial protocol.
Exclusion criteria
Exclusion criteria: 1. Body weight 2 times per week during the preceding 3 months • Nighttime awakenings with asthma symptoms >2 times per month during the preceding 3 months • Asthma exacerbation requiring oral corticosteroid use >2 times per year 3c. Childhood Asthma Control Test (cACT) =19 (applies only for subjects with a history of asthma age 7 to 11 years; cACT will not be performed for subjects age 2 to 6 years). 3d. Peak expiratory flow (PEF) 19, PEF testing can be repeated once within 48 hours. 4. Subjects with a current medical history of chronic bronchitis. 5. Cutaneous infection within 1 week before the baseline visit or any infection requiring treatment with oral or parenteral antibiotics, antivirals, antiparasitics, or antifungals within 2 weeks before the baseline visit, or any confirmed or suspected coronavirus disease (COVID-19) infection within 2 weeks before the screening or baseline visit. Subjects may be rescreened once the infection has resolved. Resolution of COVID-19 infection can be confirmed by recovery assessment methods, as described in Section 8.3.4.2. 6. Requiring rescue therapy for AD during the run-in period or expected to require rescue therapy within 2 weeks following the baseline visit. 7. Positive serology results for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb), hepatitis C (HCV) antibody with positive confirmatory test for HCV (eg polymerase chain reaction [PCR]), or human immunodeficiency virus (HIV) antibody at the screening visit. Note: Subjects with a positive HBcAb and a negative HBsAg can be included in this clinical trial if hepatitis B surface antibody (HBsAb) is positive (considered immune after a natural infection). Subjects with negative confirmatory test for HCV can be included in this clinical study. In the event of rescreening, the serology tests results (e.g. HBV, HCV, HIV) from the first screening can be used by the investigator to assess the eligibility of rescreened subjects if those tests were performed within 6 weeks prior to the baseline visit. 8. Current active tuberculosis (TB) or latent TB infection or history of either untreated or inadequately treated latent or active TB according to the local applicable guidelines. Note: Subjects who have a documented history of completion of an appropriate TB treatment regimen for latent or active TB with no history of re-exposure to TB since their treatment was completed are eligible to participate in the study. In the event of rescreening, the TB tests result from the first screening can be used by the investigator to assess the eligibility of rescreened subjects if t
