Abstract
Introduction
Atopic dermatitis (AD) affects multiple areas of the body, some of which may be more refractory to treatment. We evaluated improvements in the Eczema Area and Severity Index (EASI) by body region and clinical signs for each body region in lebrikizumab-treated patients with moderate-to-severe AD.
Methods
ADvocate 1 and ADvocate 2 compared lebrikizumab 250 mg as monotherapy every 2 weeks versus placebo for 16 weeks. Efficacy measures included EASI, which rates the extent and severity of four clinical signs (erythema, edema/papulation, excoriation, lichenification) in four body regions (head/neck, upper extremities, trunk, lower extremities). Analyses are post hoc.
Results
Mean baseline EASI, body region EASI subscores, and the severity of clinical signs were consistent across both studies (EASI ranging from 16.0 to 72.0). At week 16 in both studies, patients treated with lebrikizumab showed significantly greater percent improvement in EASI across all body regions versus placebo (p ≤ 0.001), with improvements as early as week 2. In ADvocate 1, all clinical signs significantly improved across all body regions at week 16 with lebrikizumab (51.4–71.6% improvement) versus placebo (23.1–43.5%, p ≤ 0.001), with significant improvements as early as week 2 for all signs. Significant improvements for all clinical signs at week 16 were also seen in ADvocate 2 for lebrikizumab (53.5–75.6%) versus placebo (28.5–41.2%, p ≤ 0.001) and as early as week 2 for all body regions and signs except head/neck erythema and lower extremity erythema, edema/papulation, and lichenification, which showed significant improvement by week 4.
Conclusions
Lebrikizumab as monotherapy consistently and rapidly reduced the extent of involvement and severity of AD in all EASI clinical signs and body regions, including the head and neck region and clinical sign of lichenification, compared with placebo.

Introduction
Atopic dermatitis (AD) is a chronic, pruritic, inflammatory skin disease with varying signs, including erythema, induration, excoriation, and lichenification, which can affect different body areas that may respond differently to therapy. Visible lesions on the head and neck or fingers and hands adversely affect patients’ quality of life more than lesions on other areas of the body [1]. Head and neck erythema in particular can have a profound impact on patients as it is difficult to conceal and its treatment can be challenging as prolonged use of topical corticosteroids can lead to perioral dermatitis, skin atrophy, and steroid withdrawal [2].
The Eczema Area and Severity Index (EASI) is commonly used to assess severity for four clinical signs of AD (erythema, edema/papulation, excoriation, lichenification) across four body regions (head/neck, upper extremities, trunk, lower extremities) in aggregate, yielding an overall score of 0 (no AD) to 72 (most severe AD). Improvement of baseline EASI by ≥ 75% (EASI 75) is an established and clinically meaningful endpoint used in AD clinical trials [3,4,5]. Response patterns of clinical improvement of AD have been characterized across body regions and clinical signs using EASI in patients treated with dupilumab [6, 7] and abrocitinib [8], which enhances clinician understanding of treatment responses and helps effectively communicate treatment expectations to patients who may have concerns about specific body areas that cause the most physical or mental burden.
Lebrikizumab is a monoclonal antibody that binds with high affinity and slow off-rate to interleukin (IL)-13, the primary cytokine in the pathogenesis of AD [9,10,11], thereby blocking downstream effects of IL-13 with high potency [12]. In completed phase 2 and 3 clinical trials, lebrikizumab as monotherapy and in combination with topical corticosteroids improved signs and symptoms of AD in adolescent and adult patients [13,14,15,16]. The primary aims of this analysis were to evaluate the efficacy of lebrikizumab across body regions and to determine how clinical signs were affected by lebrikizumab in patients with moderate-to-severe AD.
Methods
Study Design
Data for this analysis are from two identically designed, multicenter, randomized, double-blind, placebo-controlled, parallel-group, phase 3 trials in the lebrikizumab AD clinical program, ADvocate 1 (NCT04146363) and ADvocate 2 (NCT04178967) (Fig. 1) [15]. Eligible patients with moderate-to-severe AD (adolescents ≥ 12 to < 18 years weighing ≥ 40 kg and adults [≥ 18 years], with EASI ≥ 16, Investigator Global Assessment [IGA] ≥ 3, ≥ 10% of total body surface area affected, chronic AD for ≥ 1 year, and for whom topical treatment was inadequate or inadvisable) were randomized 2:1 to lebrikizumab 250 mg every 2 weeks with a 500-mg loading dose at week 0 and week 2, or placebo. Data from the 16-week placebo-controlled period of each study are presented here. Studies were conducted in accordance with the Declaration of Helsinki and the International Council for the Harmonization of Good Clinical Practice Guideline and approved by individual institutional review boards at each participating study center. All patients provided written informed consent.
Outcomes
Efficacy was assessed using EASI [17, 18], ranging from 0 to 72. The amount of involvement for each body region (head/neck, upper extremities, trunk, lower extremities) is evaluated and assigned an area score as follows: 1 (1–9%), 2 (10–29%), 3 (30–49%), 4 (50–69%), 5 (70–89%), and 6 (90–100%). Next, each body region is assessed individually for severity of four clinical signs (erythema, edema/papulation, excoriation, lichenification) on a scale of 0 (no involvement) to 3 (severe involvement); half points can be used between scores 1 and 3. Additionally, each body region is assigned a multiplier (age ≥ 8 years old): head/neck (0.1), upper extremities (0.2), trunk (0.3), lower extremities (0.4). Finally, the body region severity score is multiplied by the area score and the multiplier, and body region subscores are added together for the total EASI. Categories of AD severity based on EASI are defined as clear: 0; almost clear: 0.1–1.0; mild: 1.1–7.0; moderate: 7.1–21.0; severe: 21.1–50.0; or very severe: 50.1–72.0 [18]. We analyzed the EASI total score across both studies, the four region subscores, and the severity of each clinical sign for the four body regions. We also analyzed the proportion of patients who achieved 100% clearance overall (EASI 100) and for each body region.
Statistical Analysis
Efficacy analyses in ADvocate 1 were based on the intent-to-treat population (all randomized patients). In ADvocate 2, a total of 18 patients from a single study site were excluded from the intent-to-treat population since some or all the study participants’ eligibility criteria could not be confirmed to have moderate-to-severe AD. Thus the efficacy analyses in ADvocate 2 were based on the modified intent-to-treat population. To better understand the baseline severity of AD of patients entering the studies, the distribution of individual baseline EASI is presented for the pooled modified intent-to-treat population from ADvocate 1 and ADvocate 2.
In this post hoc analysis, EASI improvement was evaluated for each study via change from baseline to week 16 for each body region subscore and for each clinical sign by body region using the mixed-effects model of repeated measures. EASI least squares mean change from baseline was converted to percent change from baseline by dividing the baseline mean for each body region and for each clinical sign in each body region. For continuous variables, data after rescue therapy (topical or systemic) and discontinuation of treatment were considered missing. To provide a visual presentation of EASI improvement, the changes in EASI total score from baseline to week 16 were animated in a rainfall plot by treatment arms, with EASI percent change from baseline intervals (< 50%, 50–75%, 75–90%, ≥ 90%) indicated by different colors. Observed data up to rescue medication use or treatment discontinuation were plotted in the animation.
To analyze the proportion of patients who achieved 100% clearance, Cochran-Mantel-Haenszel test compared lebrikizumab treatment versus placebo for overall EASI 100 and within patients whose baseline subscore was > 0 for each body region’s 100% clearance. For these categorical variables, data after rescue therapy (topical or systemic) or treatment discontinuation and any intermittent missing data were analyzed as non-response. The analyses reported here were not controlled for type I error or multiplicity; therefore, nominal p-values are reported. The statistical results were confirmed through replicate statistical programming, validation, and quality reviews.
Results
A total of 424 and 427 patients were enrolled in ADvocate 1 and ADvocate 2, respectively. Patient demographics and disease characteristics were similar across both trials and treatment groups (Table 1). Mean age was approximately 36 years across both studies, and 13.0% and 11.0% of patients were ≥ 12 to < 18 years old in ADvocate 1 and ADvocate 2, respectively (Table 1). The mean percentage of body surface area affected ranged from 45.3 to 47.8% across treatment groups, and most patients (≥ 89.7%) were affected in each body region. Baseline mean EASI total scores between treatment arms were numerically comparable for ADvocate 1 (placebo, 31.0; lebrikizumab 28.8) and ADvocate 2 (placebo, 29.6; lebrikizumab, 29.7), as were EASI body region subscores (Table 1) and EASI clinical signs by body region (Table 2).
EASI Total Scores from Week 0 to Week 16
The distribution of baseline EASI in pooled data from the two studies ranged from 16.0 (minimum required for study entry) to 72.0 (Fig. 2). Based on the EASI categories of disease severity, most patients had severe disease (EASI 21.1–50.0; 67.3% and 63.7% in the placebo and lebrikizumab treatment groups, respectively); 8.0% and 7.5% of patients, respectively, had very severe disease (EASI > 50.1). Change in EASI total score for individual patients treated with lebrikizumab and placebo from week 0 to week 16 in ADvocate 1 and ADvocate 2 is shown in an animation rainfall plot (animation) and at week 16 (Fig. 3). The animation and figure visually show individual patients as they progress through percentage improvement in EASI from < 50 to 50–75%, 75–90%, and ≥ 90%. At week 16 of ADvocate 1, 10.6% of lebrikizumab-treated patients and 0.0% of placebo-treated patients achieved EASI 100 (p < 0.001); at week 16 of ADvocate 2, 10.3% versus 0.7% of lebrikizumab- and placebo-treated patients, respectively, achieved EASI 100 (p < 0.001).

EASI Body Regions
Lebrikizumab improved EASI across all body regions as early as week 2 versus placebo in both ADvocate 1 and ADvocate 2 (Fig. 4). At week 16 of ADvocate 1, patients treated with lebrikizumab showed statistically significant improvement in EASI across all body regions versus placebo (head/neck, 68.2% vs. 35.1%; upper extremities, 71.3% vs. 31.9%; trunk, 74.3% vs. 37.1%; lower extremities, 71.4% vs. 34.8%; p ≤ 0.001 for all comparisons) (Fig. 4a). Similar improvements in lebrikizumab versus placebo were noted at week 16 of ADvocate 2 (head/neck, 66.8% vs. 37.3%; upper extremities, 70.9% vs. 33.7%; trunk, 74.9% vs. 40.2%; lower extremities, 75.3% vs. 42.7%; p < 0.001 for all comparisons) (Fig. 4b).
At week 16 of ADvocate 1, a greater proportion of patients treated with lebrikizumab achieved 100% clearance for each body region versus placebo (head/neck: 33.0% vs. 10.6%; upper extremities: 23.0% vs. 2.1%; trunk: 34.3% vs. 7.2%; lower extremities: 28.9% vs. 6.5%; p < 0.001 for all comparisons) (Fig. 5a). Lebrikizumab-treated patients achieved EASI 100 most rapidly and at significantly higher proportions than placebo-treated patients in the head/neck (15.4% vs. 3.8%; p ≤ 0.001) and lower extremities (9.6% vs. 3.6%; p ≤ 0.05) by week 4, and then trunk (18.9% vs. 6.5%; p ≤ 0.001) and upper extremities (7.4% vs. 2.1%; p ≤ 0.05) by week 6 (Fig. 5a). In ADvocate 2 at week 16, significantly greater proportions of patients treated with lebrikizumab achieved 100% clearance for each body region (head/neck: 29.1% vs. 10.9%; upper extremities: 19.6% vs. 4.2%; trunk: 28.6% vs. 9.1%; lower extremities: 20.1% vs. 8.3%; p < 0.001 for all comparisons) (Fig. 5b).
EASI Clinical Signs in Each Body Region
Improvement in all clinical signs across all body regions showed statistical significance at week 16 in both studies (p < 0.001) (Figs. 6 and 7). For ADvocate 1, a statistically significant improvement from baseline in all four clinical signs was seen as early as week 2 with lebrikizumab treatment versus placebo for head/neck and trunk (p < 0.001), and for upper extremities and lower extremities (p < 0.01) (Fig. 6a). For ADvocate 2, a statistically significant improvement from baseline was seen for head/neck as early as week 2 for edema/papulation, excoriation, and lichenification, and as early as week 4 for erythema with lebrikizumab treatment versus placebo (p < 0.05). For trunk and upper extremities, statistically significant improvement for all four signs versus placebo was seen as early as week 2 (p < 0.05), and for lower extremities, improvement was seen by week 2 for excoriation (p < 0.001) and by week 4 for erythema, edema/papulation, and lichenification (p < 0.001) (Fig. 6b).
Discussion
In this analysis of two placebo-controlled, randomized, phase 3 trials in adolescent and adult patients with moderate-to-severe AD, baseline EASI scores are represented across the disease severity ranges of moderate, severe, and very severe. Lebrikizumab reduced the extent of involvement across all body regions, including the head/neck, as early as 2 weeks after initiating treatment, and response was maintained through week 16. Additionally, approximately one-third of lebrikizumab-treated patients achieved 100% clearance of the head/neck and trunk by week 16, and lebrikizumab improved all four clinical signs of disease across all body regions. Lebrikizumab showed efficacy for head/neck involvement, which can be difficult to treat, and improved lichenification in all regions.
While lebrikizumab was effective across all body regions, a progressive trend in the proportion of patients achieving EASI 100 was observed. Complete skin clearance of the head/neck and lower extremity regions occurred earliest followed by the trunk and lower extremities. These findings can support healthcare professionals in discussions of treatment expectations with patients.
Real-world studies have shown that EASI head/neck subscores have a larger impact on quality of life than trunk and limb subscores [19], and the extent of facial involvement has been significantly correlated with lower quality of life [20]. The head and neck have historically been difficult to treat. The use of topical corticosteroids for treatment of head and neck AD is limited because of concerns about potential adverse events, including cutaneous atrophy, perioral dermatitis, and steroid withdrawal [2]. Other treatment options, such as topical calcineurin inhibitors and crisaborole, have been associated with a burning sensation and cutaneous irritation; therefore, local tolerability is a concern [21]. While studies of dupilumab using similar analyses to those herein have found improvement in the head/neck region by EASI, real-world cases of head/neck erythema adverse events have been reported with dupilumab [22, 23]. A recent analysis of treatment-emergent adverse events of facial, head, and neck erythema in four placebo-controlled lebrikizumab clinical trials for moderate-to-severe AD did not reveal a difference between lebrikizumab and placebo at week 16, while an analysis of all patients who received at least one dose of lebrikizumab in eight clinical trials showed that the incidence rate of adverse events of facial, head, and neck erythema did not increase with longer exposure to lebrikizumab [24]. At this time, it is not definitively known whether lebrikizumab may be associated with head and neck erythema, as it has not been extensively utilized in the real-world setting.
Lichenification is usually more difficult to treat relative to other clinical signs of AD, and prevalence can vary among populations. A recent real-world analysis of disease severity at study enrollment found more severe lichenification in Black patients versus White patients for all body regions [25]. In this study, lichenification was nearly resolved across all body regions at week 16 with lebrikizumab treatment.
There are limitations to this study. The data presented here are from the initial 16-week period of the trials. This study also includes limitations inherent to post hoc analyses, such as the lack of a clear a priori hypothesis for testing.
Conclusions
Lebrikizumab as monotherapy consistently reduced the severity of AD and the extent of involvement across all body regions, including the head and neck, compared with placebo. Lebrikizumab also reduced the severity of all four clinical signs of AD, including lichenification, in all body regions. In addition, a significantly higher proportion of lebrikizumab-treated patients achieved EASI 100.
