Group Intervention Description Lebrikizumab 250 mg Every 4 weeks (Q4W) Lebrikizumab Participants received 500 mg of Lebrikizumab (2 x 250 mg) subcutaneous (SC) injections as a loading dose at Baseline followed by 250 mg of Lebrikizumab administered SC Q4W from Week 4 until Week 12, in combination with topical corticosteroid. Week 16 responders entered maintenance period and continued with the same treatment. Week 16 non responders entered Escape Arm and received Lebrikizumab 250 mg Q2W until Week 68. Lebrikizumab 250 mg Every 2 weeks (Q2W) Lebrikizumab Participants received 500 mg of Lebrikizumab (2 x 250 mg) SC injections as a loading dose at Baseline and Week 2 followed by 250 mg of Lebrikizumab administered SC Q2W from Week 4 until Week 14, in combination with topical corticosteroid. Week 16 responders entered maintenance period and were randomly allocated to receive 250 mg lebrikizumab Q2W or 250 mg lebrikizumab Q4W, in a 1:1 ratio. Week 16 non responders entered Escape Arm and received Lebrikizumab 250 mg Q2W until Week 68. Placebo Placebo Participants received two SC injections of Placebo as a loading dose at Baseline in combination with topical corticosteroid and Week 2 followed by a single injection Q2W from Week 4 until Week 14. Week 16 responders entered maintenance period and continued with the same treatment. Week 16 non responders entered Escape Arm and received Lebrikizumab 250 mg Q2W until Week 68. Placebo Topical Corticosteroid Participants received two SC injections of Placebo as a loading dose at Baseline in combination with topical corticosteroid and Week 2 followed by a single injection Q2W from Week 4 until Week 14. Week 16 responders entered maintenance period and continued with the same treatment. Week 16 non responders entered Escape Arm and received Lebrikizumab 250 mg Q2W until Week 68. Lebrikizumab 250 mg Every 4 weeks (Q4W) Topical Corticosteroid Participants received 500 mg of Lebrikizumab (2 x 250 mg) subcutaneous (SC) injections as a loading dose at Baseline followed by 250 mg of Lebrikizumab administered SC Q4W from Week 4 until Week 12, in combination with topical corticosteroid.

- Primary Outcome Measures
Name Time Method Percentage of Participants With an Investigators Global Assessment (IGA) Score of 0 or 1 and a Reduction ≥2 Points From Baseline to Week 16 Baseline to Week 16 The IGA measures the investigator's global assessment of the participant's overall severity of their atopic dermatitis (AD), based on a static, numeric 5-point scale from 0 (clear skin) to 4 (severe disease). The score is based on an overall assessment of the degree of erythema, papulation/induration, oozing/crusting, and lichenification.
Percentage of Participants Achieving Eczema Area Severity Index-75 (EASI-75) (≥75% Reduction in EASI Score) at Week 16 Week 16 The EASI assesses objective physician estimates of 2 dimensions of atopic dermatitis - disease extent, i.e., percentage of skin 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-75 score was obtained by weight-averaging these 4 scores and will range from 0 (none) to 72 (severe).
The EASI-75 responder is defined as a participant who achieves a ≥ 75% improvement from baseline in the EASI score.
- Secondary Outcome Measures

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).
Least Square (LS) Mean was calculated using ANCOVA model with treatment, stratification factors of geographic region, age group, baseline IGA score (IGA 3 versus 4) as fixed factors baseline value as covariate.Percentage of Participants Achieving EASI-90 at Week 16 Week 16 The EASI assesses objective physician estimates of 2 dimensions of AD - 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-90 responder is defined as a participant who achieves a ≥ 90% reduction from baseline in the EASI score.Percentage of Participants With an Itch Numeric Rating Scale (NRS) Score of ≥4-points at Baseline Who Achieve A ≥4-point Reduction From Baseline to Week 1 Baseline to Week 1 The Itch Numeric Rating Scale (NRS) is a an 11-point scale used by participants to rate their worst itch severity over the past 24 hours with 0 indicating "No itch" and 10 indicating "Worst itch imaginable."
Percentage of Participants With an Itch NRS Score of ≥4-points at Baseline Who Achieve A ≥4-point Reduction From Baseline to Week 16 Baseline to Week 16 The Itch Numeric Rating Scale (NRS) is a an 11-point scale used by participants to rate their worst itch severity over the past 24 hours with 0 indicating "No itch" and 10 indicating "Worst itch imaginable."
Percentage of Participants With an Itch NRS Score of ≥4-points at Baseline Who Achieve A ≥4-point Reduction From Baseline to Week 2 Baseline to Week 2 The Itch Numeric Rating Scale (NRS) is a an 11-point scale used by participants to rate their worst itch severity over the past 24 hours with 0 indicating "No itch" and 10 indicating "Worst itch imaginable."
Percentage of Participants With an Itch NRS Score of ≥4-points at Baseline Who Achieve A ≥4-point Reduction From Baseline to Week 4 Baseline to Week 4 The Itch Numeric Rating Scale (NRS) is a an 11-point scale used by participants to rate their worst itch severity over the past 24 hours with 0 indicating "No itch" and 10 indicating "Worst itch imaginable."
