A Study of Lebrikizumab Treatment in Adults and Adolescents With Moderate-to-Severe Atopic Dermatitis (ADhope 2)

A Phase 3, 2-Part, Open-Label and Double-Blind, Randomised Study to Evaluate the Effectiveness and Safety of Lebrikizumab Treatment in Adults and Adolescents With Moderate-to-Severe Atopic Dermatitis

The main purpose of this study is to evaluate the effectiveness of 24 weeks of lebrikizumab in improving disease severity, signs, and symptoms in adults and adolescents with moderate-to-severe AD in Part 1 and to describe how similar is the current maintenance dosing regimen of lebrikizumab 250 mg every 4 weeks (Q4W) to the new proposed; lebrikizumab 500 mg every 12 weeks (Q12W), in terms of efficacy, safety, PK, ADA and blood biomarkers.

Study Overview

• Status: Active, not recruiting
• Conditions: Eczema; Dermatitis, Atopic
• Intervention / Treatment: Biological: Lebrikizumab; Other: Placebo

Detailed Description

This study consists of two parts. Part 1 is a single-arm, open-label design, where participants will receive lebrikizumab subcutaneous (SC) injections up to Week 24. Part 2 is a randomized, double-blind design, in which participants who achieve clinical response in Part 1 will continue receiving lebrikizumab treatment across two periods: a Run-in period and a Double-blind period. Participants who do not maintain at least a 50% reduction in Eczema Area and Severity Index (EASI) from baseline during Double-Blind Period will enter an Escape Arm.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Part 1: Percentage of Participants Achieving Eczema Area and Severity Index (EASI) Score Less than or Equal to (<=) 7 at Week 24	The EASI is used to assess the severity and extent of AD; it is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and or extensive disease. The severity of erythema, induration/papulation, excoriation, and lichenification will be assessed by the Investigator or trained designee on a scale of 0 (absent) to 3 (severe) for each of the 4 body areas: head/neck, trunk, upper limbs, and lower limbs, with half points allowed. In addition, the extent of AD involvement in each of the 4 body areas will be assessed as a percentage by body area of head/neck, trunk, upper limbs, and lower limbs, and converted to a score of 0 (0%), 1 (0 to 9%), 2 (10 to 29%), 3 (30 to 49%), 4 (50 to 69%), 5 (70 to 89%) and 6 (90 to 100%).	At Week 24
Part 2: Percentage of Participants Achieving EASI 75 at Week 36	The EASI is used to assess the severity and extent of AD; it is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and or extensive disease. EASI 75 is defined as 75% reduction from baseline in the EASI score.	At Week 36
Part 2: Percentage of Participants with an IGA Score of 0 or 1 and a Reduction >=2 Points	The IGA is an instrument used to globally rate the severity of the participant's AD. It is based on a 5-point scale ranging from 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate) and 4 (severe), and a score is selected using descriptors that best describe the overall appearance of the lesions at a given time point. The score is based on an overall assessment of the degree of erythema, papulation/induration, oozing/crusting (minimal, palpable induration and significant induration).	From Baseline (Part 1) up to Week 36

Part 1: Percentage Change From Baseline in Modified Total Lesion Symptom Score (mTLSS) at Week 24	mTLSS combines an evaluation of hand eczema lesions severity including 6 key signs (erythema, desquamation, lichenification/hyperkeratosis, vesiculae, oedema, fissures) and the intensity of pruritus and pain. The seven features of AD of the hand (erythema, scaling, lichenification/hyperkeratosis, vesiculation, oedema, fissures, pruritus/pain) form the composite scale of mTLSS' strength and each one of them scores from 0 (mild) to 3 (severe).

Part 1: Percentage of Participants Achieving Dermatology Life Quality Index (DLQI) 0-1 at Week 24	The DLQI is a 10-item validated questionnaire completed by the participant or caregiver used to assess the impact of skin disease on the participant's QoL during the previous week. The 10 questions cover the following topics: symptoms, embarrassment, shopping and home care, clothes, social and leisure, sport, work or study, close relationships, sex, and treatment. Each question is scored from 0=not at all, 1=a little, 2=a lot, and 3=very much, giving a total score ranging from 0 to 30. A high score is indicative of a poor QoL. DLQI scores indicates 0-1 (no effect on patient's life), 2-5 (small effect on patient's life), 6-10 (moderate effect on patient's life), 11-20 (very large effect on patient's life), 21-30 (extremely large effect on patient's life)	At Week 24

The answers to the questions are generally scored on a 4-point scale from 0=not at all or question unanswered, 1=only a little, 2=quite a lot, 3=very much. cDLQI is calculated by summing the score of each question resulting in 0 to 30. Higher the score, the more impairment of the child's life is experienced.	At Week 24
