入排标准
入选标准
- •All participants must have prior treatment with dupilumab meeting one of the following conditions:
- •Participants who stopped dupilumab treatment due to non-response, partial response, loss of efficacy must have been previously treated with dupilumab (at labeled dose level) for at least 4 months.
- •Participants who stopped dupilumab treatment due to intolerance or adverse events (AEs) to the drug may enter the study with no required prior length of dupilumab treatment.
- •Participants who stopped dupilumab treatment due to cost or loss of access to dupilumab (for example, insurance coverage) may enter the study with no required prior length of dupilumab treatment.
- •Participants who have chronic AD that has been present for ≥1 year before screening.
- •Have EASI ≥16 at baseline
- •Have IGA score ≥3 (Scale of 0 to 4) at baseline
- •Have ≥10% body surface area (BSA) of AD involvement at baseline
- •Have a history of inadequate response to treatment with topical medications; or determination that topical treatments are otherwise medically inadvisable.
- •Adolescents body weight must be ≥40 kg at baseline.
排除标准
- •History of human immunodeficiency virus (HIV) infection or positive HIV serology at screening.
- •Have a current infection or chronic infection with hepatitis B virus (HBV) at screening (that is, positive for hepatitis B surface antigen and/or polymerase chain reaction positive for HBV DNA
- •Have a current infection with hepatitis C virus (HCV) at screening (that is, positive for HCV RNA
- •Have an uncontrolled chronic disease that might require multiple intermittent uses of oral corticosteroids at screening, as defined by the investigator.

研究组 & 干预措施
Lebrikizumab 250 mg Q2W
Participants received a 500 milligram (mg) loading dose of Lebrikizumab subcutaneously (SC) once every 2 weeks (Q2W) at baseline and Week 2, followed by 250 mg SC once Q2W until Week 16.
干预措施: Lebrikizumab
Lebrikizumab 250 mg Q2W to Lebrikizumab 250 mg Q2W
Participants who received Lebrikizumab 250 mg SC once Q2W until Week 16 and who did not achieve Investigator Global Assessment (IGA) 0 or 1 (clear or almost clear) or a 75% reduction in the Eczema Area and Severity Index (EASI) score from baseline (EASI-75) at Week 16 continued to receive 250 mg SC once Q2W until Week 24. Eligible participants entered the Continued Access Period, receiving the assigned same dose until the product was commercially available in the United States or discontinuation criteria were met.
干预措施: Lebrikizumab
Lebrikizumab 250 mg Q2W to Lebrikizumab 250 mg Q4W
Participants who received Lebrikizumab 250 mg SC once Q2W until Week 16 and who achieved IGA 0 or 1 (clear or almost clear) or a 75% reduction in the EASI score from baseline (EASI-75) at Week 16 continued to receive 250 mg SC once Q2W until Week 24. Eligible participants entered the Continued Access Period, receiving the assigned same dose until the product was commercially available in the United States or discontinuation criteria were met.

结局指标
主要结局
Percentage of Participants Achieving Eczema Area and Severity Index 75 (EASI-75) at Week 16
时间窗: Week 16
The EASI assesses objective physician estimates of 2 dimensions of atopic dermatitis - disease extent and clinical signs affected: 0 = 0%; 1 = 1-9%; 2 = 10-29%; 3 = 30-49%; 4 = 50-69%; 5 = 70-89%; 6 = 90-100% and the severity of 4 clinical signs: (1) erythema, (2) edema/papulation, (3) excoriation, and (4) lichenification each on a scale of 0 to 3 (0 = none, absent; 1 = mild; 2 = moderate; 3 = severe) at 4 body sites (head/neck, trunk, upper limbs, and lower limbs). Half scores are allowed between severities 1, 2, and 3. The final EASI score was obtained by weight-averaging these 4 scores and will range from 0 to 72 (severe). The EASI-75 responder is defined as a ≥ 75% improvement from baseline in the EASI score.
