Subjects who are HBsAg negative and HBcAb positive will be tested for Hepatitis B Surface Antibody (HBsAb) and if HBsAb is positive, may be enrolled in the study; if HBsAb is negative, the subject is not eligible for the study. For Hepatitis C, all subjects will undergo testing for Hepatitis C antibody (HCVAb) during Screening. Subjects who are HCVAb positive are not eligible for the study. Active COVID-19 infection at Baseline.
• Have known liver cirrhosis and/or chronic hepatitis of any etiology
• Known diagnosis of active tuberculosis or non-tuberculous mycobacterial infection or latent tuberculosis unless it is well documented by a specialist that the patient has been adequately treated
• Allergen immunotherapy should be discontinued 6 months before randomization

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percent change from Baseline in Eczema Area and Severity Index (EASI) at Week 16	The EASI score is used to measure the severity and extent of AD and measured erythema, infiltration, excoriation and lichenification on 4 anatomic regions of the body: head, trunk, upper and lower extremities. The total EASI score ranges from 0 (minimum) to 72 (maximum) points, with the higher scores reflecting the worse severity of AD	Baseline, Week 16
Secondary	Proportion of participants achieving validated Investigator's Global Assessment (vIGA) response of 0 (clear) or 1 (almost clear) at Week 16	IGA is an assessment scale used to determine severity of AD and clinical response to treatment on a 5-point scale (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe) based on erythema and papulation/infiltration. Therapeutic response is an IGA score of 0 (clear) or 1 (almost clear)	Week 16
Secondary	Proportion of participants with a 75% reduction Eczema Area and Severity Index 75 (EASI)	EASI scores range from 0 to 72 (severe)The EASI responder is defined as a participant who achieves a =75% improvement (EASI 75) from baseline in the EASI score	Week 16
Secondary	Proportion of participants achieving EASI 50	EASI scores range from 0 to 72 (severe)The EASI responder is defined as a participant who achieves a =50% improvement (EASI 50) from baseline in the EASI score	Week 16
Secondary	Proportion of participants achieving EASI 90	EASI scores range from 0 to 72 (severe)The EASI responder is defined as a participant who achieves a =90% improvement (EASI 90) from baseline in the EASI score	Week 16
Secondary	Proportion of participants with EASI <7	EASI scores range from 0 to 72 (severe)	Week 16
Secondary	Absolute and percent change in peak Pruritus Numerical Rating Scale (P-NRS)	The P-NRS is an 11-point scale used by patients to assess their worst itch severity over the past 24 hours, with 0 indicating no itch and 10 indicating the worst itch imaginable. Pruritus assessments will be recorded daily by the patient using an electronic diary	Week 16 and Week 24
Secondary	Proportion of participants achieving a 4-point reduction in peak Pruritus Numerical Rating Scale	Pruritus Numerical Rating Scale	Week 16
Secondary	Change in Body Surface Area (BSA) affected with AD	BSA ranges from 0% to 100 % with higher values representing greater extent of AD	Week 16 and Week 24
Secondary	Change in SCORing Atopic Dermatitis (SCORAD)	The SCORAD is a validated measure of the extent and severity of atopic dermatitis lesions, along with subjective symptoms. The score ranges from 0 to 103, with higher values indicating a more extensive and/or severe condition	Week 16 and Week 24
Secondary	Change in Dermatology Life Quality Index (DLQI)	The DLQI is a 10-item, validated questionnaire used in clinical practice and clinical trials to assess the patient's perception of the impact of AD disease symptoms and treatment on their quality of life (QoL). The 10 questions assess QoL over the past week, with an overall scoring of 0 (absent disease) to 30 (severe disease). A high score is indicative of a poor QoL	Week 16 and Week 24
Secondary	Change in Patient-Oriented Eczema Measure (POEM)	The POEM is a 7-item questionnaire that assesses disease symptoms (dryness, itching, flaking, cracking, sleep loss, bleeding and weeping) with a scoring system of 0 (absent disease) to 28 (severe disease) (high score indicative of poor QoL)	Week 16 and Week 24
Secondary	Change in European Quality of Life-5 Dimensions-5 Levels (EQ-5D-5L) Index Score United States and United Kingdom Algorithm	The EQ-5D-5L is a 2-part measurement. The second part is assessed using a visual analog scale (VAS) that ranges from 0 to 100 millimeter (mm), where 0 is the worst health you can imagine and 100 is the best health you can imagine	Week 16 and Week 24
Secondary	Absolute and percent change in sleep disturbance numerical rating scale (SD-NRS)	The SD-NRS is an 11-point scale used by patients to assess their sleep disturbance severity over the past 24 hours, with 0 indicating no or minimal sleep disturbance and 10 indicating the worst imaginable sleep disturbance. SD-NRS assessments will be recorded daily by the patient using an electronic diary	Week 16 and Week 24
