Introduction: Lebrikizumab, a high-affinity IgG4 monoclonal antibody that selectively inhibits interleukin-13 with high binding affinity and slow dissociation rate, prevents the formation of the interleukin-4Rα/interleukin-13Rα1 heterodimer receptor signaling complex. Here we report the impact of lebrikizumab on responses to two non-live vaccines in adult patients with moderate-to-severe atopic dermatitis (AD). Methods: ADopt-VA (NCT04626297) was a double-blind, placebo-controlled, parallel-group, 16-week, phase 3 randomized study to assess the impact of lebrikizumab treatment on non-live vaccine immune responses, and efficacy and safety of lebrikizumab compared with placebo. Eligible patients included adults from 18 to 55 years of age with moderate-to-severe chronic AD who were randomly assigned 1:1 to lebrikizumab 250 mg every 2 weeks or placebo and stratified according to disease severity. The primary endpoints were the development of a booster response to tetanus toxoid and a positive antibody response to meningococcal conjugate vaccine (MCV), 4 weeks after administration of the corresponding vaccine. Results: At week 16, 73.6% of patients in the lebrikizumab group (n = 78/106) achieved Tdap booster response compared with 73.4% of patients in the placebo group (n = 58/79). MCV vaccine response was observed in 86.9% of patients in the lebrikizumab group (n = 86/99) and 75.0% of patients in the placebo group (n = 60/80). At week 16, IGA 0,1 with ≥ 2-point improvement from baseline was achieved by 40.6% (n = 51/125) of patients treated with lebrikizumab and 18.9% (n = 23/122) of patients who received placebo (p < 0.001). There was a higher proportion of patients achieving EASI 75 at week 16 in the lebrikizumab-treated patients (58.0%, n = 72/125) compared with placebo (32.7%, n = 40/122, p < 0.001). Conclusions: Treatment with lebrikizumab did not impact response to non-live vaccines Tdap and MCV in this study. Lebrikizumab treatment had a significant degree of efficacy compared to placebo across multiple endpoints. Trial Registration: ClinicalTrials.gov identifier NCT04626297. [ABSTRACT FROM AUTHOR]

Introduction: Lebrikizumab is a novel monoclonal antibody with established efficacy in patients with moderate-to-severe atopic dermatitis (AD) in multiple Phase 3 trials. One of the ultimate treatment goals for patients with moderate-to-severe AD is to achieve stable disease control without concern for planning future life events. Methods: In ADvocate1 and ADvocate2, lebrikizumab-treated patients meeting the protocol-defined response criteria at Week 16 were re-randomized 2:2:1 to receive lebrikizumab every 2 weeks (Q2W), lebrikizumab every 4 weeks (Q4W), or placebo Q2W (lebrikizumab withdrawal) for 36 additional weeks. In this post hoc analysis, we evaluated the proportions of patients with no or minimal fluctuations of efficacy during the 36-week maintenance period and plotted individual patient trajectories. We defined no or minimal fluctuations as achieving and maintaining the defined endpoint (≥ 75% improvement in the Eczema Area and Severity Index [EASI 75], ≥ 90% improvement in EASI, Pruritus Numeric Rating Scale [NRS] ≥ 4-point improvement, or Pruritus NRS ≥ 3-point improvement) for ≥ 80% of the study visits. If patients used rescue medication, discontinued treatment, or transferred to the escape arm, data collected at or after the event were imputed as non-response. Results: The proportions of lebrikizumab responders who maintained EASI 75 with no or minimal fluctuations were 70.8% (lebrikizumab Q2W), 71.2% (lebrikizumab Q4W), and 60.0% (lebrikizumab withdrawal). Of the patients with baseline Pruritus NRS ≥ 4 and who achieved ≥ 4-point improvement at Week 16, 66.1% (lebrikizumab Q2W), 62.7% (lebrikizumab Q4W), and 55.2% (lebrikizumab withdrawal) maintained ≥ 4-point Pruritus NRS improvement with no or minimal fluctuations. Conclusions: Patients who met the response criteria at Week 16 and continued treatment with lebrikizumab Q2W or Q4W demonstrated a stable response with no or minimal fluctuations of efficacy in measures of skin and itch up to Week 52. Clinical Trial Registration: NCT04146363 (ADvocate1) and NCT04178967 (ADvocate2). Plain Language Summary: Atopic dermatitis, also known as atopic eczema (or just eczema), is a common skin disease that causes itchy, dry skin. Patients with eczema are often unsure of when disease flares will happen, even while receiving treatment. In two global studies, ADvocate1 and ADvocate2, lebrikizumab improved the signs and symptoms of moderate-to-severe eczema after 16 weeks of treatment. Most of these patients also saw improvement up to 52 weeks. We wanted to know if patients continued to feel better between Week 16 and Week 52. Patients who responded to lebrikizumab after 16 weeks were given lebrikizumab every 2 weeks, lebrikizumab every 4 weeks, or placebo every 2 weeks. We tested how many patients experienced stable response to therapy, which we said was maintaining the same level of improvement on skin signs and itch symptoms for at least 80% of study visits from Week 16 to Week 52. In patients treated with lebrikizumab every 2 weeks or every 4 weeks, we saw that about seven of every ten patients maintained a stable response in skin improvement and about six of every ten patients maintained stable response in itch symptoms. In patients who stopped lebrikizumab therapy, six out of every ten patients maintained a stable skin improvement and more than five of every ten patients maintained a stable improvement in itch symptoms. In ADvocate1 and ADvocate2, most lebrikizumab-treated patients showed a stable response over time on skin and itch with dosing every 2 weeks or every 4 weeks. [ABSTRACT FROM AUTHOR]

Background: Lebrikizumab demonstrated significant improvement versus placebo for measures of skin clearance and patient-reported outcomes at weeks 16 and 52 in patients with moderate-to-severe atopic dermatitis (AD). We report the sustained impact of lebrikizumab monotherapy, over 52 weeks and between visits, on the frequency of itch and sleep loss symptoms, as assessed by Patient-Oriented Eczema Measure (POEM), in patients with moderate-to-severe AD. Methods: In ADvocate1 and ADvocate2, Week-16 lebrikizumab responders (EASI75 or IGA 0/1 with ≥ 2-point improvement and without rescue medication) were randomized to lebrikizumab every 2 weeks (Q2W), every 4 weeks (Q4W), or placebo for 36 weeks. This pooled analysis reports improvement from Week 16 to 52 in patients achieving POEM response 0 (no days) or 1 (1–2 days) for Items 1 (itch) and 2 (sleep disturbance) for the lebrikizumab Q2W and Q4W treatment arms. Observed (excluding data collected after treatment discontinuation, rescue medication use, or patient transfer to escape arm) results were reported. Results: At Week 16, for lebrikizumab Q2W and Q4W, 35.9% (n = 37/103) and 39.3% (n = 42/107) of patients responded 0 or 1 to Item 1 of POEM (Itch) and 12.6% (n = 13/103) and 12.1% (n = 13/107) responded 0. A total of 66.0% (n = 68/103) and 72.6% (n = 77/106) of patients responded 0 or 1 to Item 2 of POEM (Sleep) and 37.9% (n = 39/103) and 44.3% (n = 47/106) responded 0, respectively. By Week 52, for lebrikizumab Q2W and Q4W, 44.6% (n = 29/65) and 48.0% (n = 36/75) responded 0 or 1 to Item 1 of POEM (Itch), and 21.5% (n = 14/65) and 18.7% (n = 14/75) of patients responded 0. A total of 83.1% (n = 54/65) and 78.4% (n = 58/74) responded 0 or 1 to Item 2 of POEM (Sleep), and 67.7% (n = 44/65) and 59.5% (n = 44/74) responded 0, respectively. Conclusion: Weekly POEM responses for itch and sleep disturbance remained stable between doses and visits, and continued to improve from Week 16 through 52, in lebrikizumab-treated patients, demonstrating consistent improvement over time for key AD symptoms. Trial Registration Numbers: ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967). [ABSTRACT FROM AUTHOR]

Background: Sleep loss is a key factor contributing to disease burden in people with atopic dermatitis (AD). Mitigating itch to improve sleep is an important outcome of AD treatment. This study explored the content validity and measurement properties of the Sleep-Loss Scale, a single-item rating scale for assessing itch interference with sleep in clinical trials of AD treatments. Methods: Concept elicitation and cognitive debriefing interviews were conducted with 21 adults and adolescents (12–17 years of age) with moderate-to-severe AD to develop a conceptual model of patient experience in AD and explore the content validity of the scale. Data collected from adults with moderate-to-severe AD enrolled in a phase 2b study (NCT03443024) were used to assess Sleep-Loss Scale's psychometric performance, including reliability, construct validity, and ability to detect change. Meaningful within-patient change (MWPC) thresholds were also determined using anchor-based methods. Results: Qualitative findings from concept elicitation highlighted the importance of sleep-loss related to itch in AD. Debriefing analysis of the Sleep-Loss Scale indicated that the scale was relevant, appropriate, and interpreted as intended. Trial data supported good reliability, construct validity and ability to detect improvement. MWPC was defined as a 1-point improvement using trial data, a finding supported by qualitative data. Conclusions: The Sleep-Loss Scale provides a valid and reliable patient-reported measure of the impact of itch on sleep in patients with AD, and can detect change, indicating it is fit-for-purpose to evaluate the efficacy of AD treatments in moderate-to-severe patients. Key summary points: • The Sleep-Loss Scale is a novel rating scale for assessing the impact of itch on sleep in atopic dermatitis (AD). • A mixed-methods approach was used to explore the content validity and psychometric properties of the Sleep-Loss Scale. • Qualitative results supported sleep loss as a common experience in AD and indicated that the Sleep-Loss Scale was relevant, appropriate, and interpreted as intended. • Quantitative results demonstrated the Sleep-Loss Scale is valid, reliable, and able to detect change. • The Sleep-Loss Scale was found to be fit-for-purpose for use in clinical trials of AD treatments among moderate-to-severe patients.

Introduction: Alopecia areata (AA) is an autoimmune disease associated with high rates of emotional and psychosocial distress. The analysis reported here describes the evolution of measures assessing health-related quality of life (HRQoL) and symptoms of anxiety and depression up to week 104 in patients who achieved sustained scalp hair regrowth during treatment with baricitinib in the BRAVE-AA phase III trials. Methods: This post-hoc analysis included data from the double-blind, parallel-group, randomized, placebo-controlled phase III trials BRAVE-AA1 (ClinicalTrials.gov number: NCT03570749) and BRAVE-AA2 (ClinicalTrials.gov number: NCT03899259). Adults with severe AA (defined as a Severity of Alopecia Tool [SALT] score ≥ 50) randomized to baricitinib 4 mg or baricitinib 2 mg at baseline who achieved SALT score ≤ 20 by week 36 and maintained SALT score ≤ 20 through week 104 on the same dose of baricitinib were included in this analysis of integrated data. Scalp hair regrowth (SALT score) and improvements in Skindex-16 AA Scale and Hospital Anxiety and Depression Scale (HADS) domain scores were analyzed over the 104-week period using descriptive statistics. Results: In total, 131 patients (88 on baricitinib 4 mg and 43 on baricitinib 2 mg) were included in this analysis. Across the two groups, the mean age (standard deviation) was 37.2 years (12.7), and 84 (64.1%) patients were female. The interquartile range) for time to achieve a SALT score ≤ 20 for patients treated with baricitinib 4 mg and baricitinib 2 mg was 13.1 and 19.6 weeks, respectively. By week 104, 91% (baricitinib 2 mg) and 96% (baricitinib 4 mg) of patients had achieved a SALT score ≤ 10 on baricitinib treatment. In both groups, progressive improvements in the Skindex-16 AA and HADS domain scores were observed up to week 104. Conclusion: This analysis of adults with severe AA treated with baricitinib revealed that achievement of sustained clinically meaningful scalp hair regrowth (SALT score ≤ 20) was associated with improvements in both measures of HRQoL and symptoms of anxiety and depression up to week 104.

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disease for which signs and symptoms have a negative impact on a patient's quality of life (QoL) and mental health. Here, we assess the impact of lebrikizumab on QoL and mental health after 16 weeks of treatment in patients with moderate-to-severe AD. Methods: Data were analyzed over 16 weeks from two separate phase 3, randomized, placebo-controlled, monotherapy trials (ADvocate1 and ADvocate2). Patient-reported outcomes were assessed using the following measures: Dermatology Life Quality Index (DLQI), EQ-5D-5L visual analogue scale (VAS), EQ-5D-5L index scores (UK and US), Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, and PROMIS Depression. Results: Treatment with lebrikizumab 250 mg every 2 weeks in two studies led to statistically significant improvements (based on nominal p values) versus placebo in DLQI since week 4 (the first timepoint assessed) for the following measures: change from baseline in DLQI total score (ADvocate1 − 7.8 vs − 2.8; ADvocate2 − 7.3 vs − 3.9), proportion of patients with DLQI ≥ 4-point improvement (ADvocate1 69.5% vs 36.2%; ADvocate2 60.5% vs 42.6%), DLQI total score ≤ 5 (ADvocate1 36.7% vs 8.8%; ADvocate2 29.6% vs 10.8%), and DLQI (0, 1) (ADvocate1 12.3% vs 1.7%; ADvocate2 9.2% vs 1.7%). Improvements in DLQI measures, EQ-5D-5L index scores (UK and US), and EQ-5D-5L VAS were sustained through week 16. Additionally, lebrikizumab improved PROMIS Anxiety and PROMIS Depression scores, and improvements were higher in patients with at least a mild score (≥ 55) versus placebo for PROMIS Anxiety (ADvocate1 − 7.43 vs − 1.51; ADvocate2 − 4.95 vs − 0.82) and PROMIS Depression (ADvocate1 − 7.42 vs − 2.46; ADvocate2 − 4.28 vs − 2.00). Conclusions: Treatment with monotherapy 250 mg lebrikizumab for 16 weeks provided clinically meaningful improvements in outcomes related to QoL and mental health for patients with moderate-to-severe AD. Lebrikizumab-treated patients reported improvements in DLQI as early as week 4, the first measure since baseline.

Background: Lebrikizumab improved itch, interference of itch on sleep, and quality of life (QoL) in patients with moderate-to-severe atopic dermatitis (AD), in two Phase 3 trials at 16weeks compared to placebo. Objectives: We assess improvements in itch and sleep interference due to itch and their impact on QoL measurements after treatment. Methods: Data were analyzed from ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967) in patients with moderate-to-severe AD. QoL was evaluated using Dermatology Life Quality Index (DLQI) at Week 16 in patients (>16years of age) who were itch responders/non-responders (defined as ≥4-point improvement in Pruritus Numeric Rating Scale) or Sleep-Loss Scale responders/non-responders (defined as ≥2-point improvement in itch interference on sleep). Results: In ADvocate1 and ADvocate2, significantly greater proportions of itch responders had a clinically meaningful improvement in measures related to QoL (DLQI scores (0/1), ≤5 DLQI total score and ≥4-point DLQI improvement) compared to itch non-responders. In both studies, a significantly greater proportion of Sleep-Loss Scale responders, reported a DLQI score of (0/1), DLQI total score of ≤5 and DLQI improvement of ≥4 points compared to Sleep-Loss Scale non-responders. Conclusions: Improvement in itch and sleep interference due to itch is associated with improvement in the QoL of patients after treatment with lebrikizumab for moderate-to-severe AD.

Background: Lebrikizumab, a high-affinity monoclonal antibody targeting IL-13, previously demonstrated clinical efficacy in three randomized, double-blind, placebo-controlled Phase 3 trials that included adults and adolescents with moderate-to-severe atopic dermatitis (AD): ADvocate1, ADvocate2, and ADhere. Aim: This subset analysis evaluated 16-week physician- and patient-reported outcomes of lebrikizumab in the adolescent patients enrolled in these three trials. Methods: Eligible adolescents (≥12 to <18years weighing ≥40kg) were randomized 2:1 to subcutaneous lebrikizumab (500mg loading doses at baseline and Week 2 followed by 250mg every 2weeks) or placebo as monotherapy in ADvocate1&2, and in combination with topical corticosteroids (TCS) in the ADhere study. Week 16 analyses included clinical efficacy outcomes (IGA (0,1) with ≥2-point improvement, EASI 75, EASI 90), patient-reported Pruritus NRS ≥4-point improvement and Sleep-Loss Scale ≥2-point improvement. Results: Pooled ADvocate1&2 16-week results in lebrikizumab (N=67) vs placebo (N=35) were: IGA (0,1) 46.6% vs 14.3% (p<0.01), EASI 75 62.0% vs 17.3% (p<0.001), EASI 90 40.7% vs 11.5% (p<0.01), Pruritus NRS 48.9% vs 13.1% (p<0.01), and Sleep-Loss Scale 26.9% vs 6.9% (p=0.137). Corresponding results for ADhere, (lebrikizumab+TCS, N=32; placebo+TCS, N=14), were consistent. Conclusions: Lebrikizumab treatment demonstrated efficacy in improving the signs and symptoms of AD in adolescent patients, consistent with the ADvocate and ADhere overall population results.

Introduction: Atopic dermatitis is associated with intense itch, which has been shown to cause sleep disruption that significantly impacts the lives of patients with atopic dermatitis. Despite this, little is known about its burden to the healthcare system and society. This study aimed to quantify the economic burden of itch-related sleep loss in moderate-to-severe atopic dermatitis in the UK. Methods: A literature-based decision-analytic model was developed from a healthcare payer and societal perspective. The model quantifies the economic burden by linking the severity of itch to the number of days of sleep disruption. The model captures the direct costs of healthcare resource utilization and treatment alongside the indirect costs of productivity loss from absenteeism and presenteeism at work over a 5-year time horizon. The patient population considered was patients aged ≥ 15 years with moderate-to-severe atopic dermatitis and itch-related sleep disruption. Results: The model estimated that itch-related sleep disruption as a result of moderate-to-severe atopic dermatitis would affect an average of 821,142 people over the time horizon (2022 to 2026). This translates into an average net economic burden of £3.8 billion (£4687 per patient), with an average of 172 million days being affected by sleep disruption per year in the UK. The greatest contributor to the annual average net economic burden was productivity loss from absenteeism and presenteeism, each accounting for 34%. The direct costs (treatment costs and healthcare resource use) accounted for 32% of the net economic burden. The results showed a high and gradually increasing economic burden over the 5-year time horizon. Conclusions: Sleep disruption has a high economic burden and reducing itch may provide substantial direct and indirect savings. Quantifying the economic burden of itch-related sleep loss may provide support for analyses to inform public health policies for treatment of atopic dermatitis, particularly within the moderate-to-severe level.

Background: Pruritus, or itch, is a key symptom of atopic dermatitis (AD); as such, mitigating itch is an important outcome of AD treatment. This study explored the content validity and measurement properties of the Pruritus Numeric Rating Scale (Pruritus NRS), a novel single-item scale for assessing itch severity in clinical trials of AD treatments. Methods: In this mixed-methods study, qualitative interviews were conducted with 21 people with moderate-to-severe AD (n = 15 adult, n = 6 adolescent) to develop a conceptual model of the patient experience in AD and explore the content validity of the Pruritus NRS. Data collected daily from adults with moderate-to-severe AD enrolled in a phase 2b study (NCT03443024) were used to assess the Pruritus NRS' psychometric performance, including reliability, construct validity, and responsiveness. Meaningful within-patient change (MWPC) thresholds were also determined using anchor-based methods. Results: Qualitative findings highlighted the importance of itch in AD, including severity, persistence, frequency, and daily life interference. Patient debriefing of the Pruritus NRS indicated that the scale was relevant, appropriate, and interpreted as intended. Trial data supported overall good psychometric properties. MWPC was defined as a 3-point improvement in Pruritus NRS score, a finding supported by qualitative data. Conclusions: The Pruritus NRS provides a valid and reliable patient-reported measure of itching severity in patients with moderate-to-severe AD, and can detect change, indicating it is fit-for-purpose to evaluate the efficacy of AD treatments in this population. Trial Registration: ClinicalTrials.gov identifier, NCT03443024. [ABSTRACT FROM AUTHOR]

Introduction/Background Atopic dermatitis (AD) has different clinical presentations, pathophysiology, comorbidity frequencies, and genetic profiles in adult-onset vs childhood-onset disease. Based on these differences, it is plausible that treatment response would also be different between adult- and childhood-onset AD. Lebrikizumab, a novel, high affinity monoclonal antibody, selectively targeting IL-13 with high affinity and slow dissociation rate, has been approved in the EU, UK, and Japan and is under investigation in the US and elsewhere for the treatment of moderate-to-severe AD. Objectives To evaluate the Week-16 efficacy of lebrikizumab monotherapy by age of AD onset in adults and adolescents with moderate-to-severe AD from ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967), identically-designed, randomized, double-blind, placebo-controlled phase 3 trials. Methods In ADvocate1 and ADvocate2, eligible patients were randomly allocated 2:1 to receive lebrikizumab 250 mg or placebo every 2 weeks. The date of AD onset was collected, and age of onset was calculated accordingly. Patients were stratified by age of AD-onset as ≤2, >2-to-<18, and ≥18 years. Efficacy was assessed at Week 16 with the proportion of patients with Investigator's Global Assessment score of 0 or 1 with ≥2-point improvement (IGA 0,1; the trials' primary endpoint); ≥75% (EASI 75) and ≥90% (EASI 90) improvement in the Eczema Area and Severity Index from baseline; ≥4-point Pruritus Numeric Rating Scale (NRS) improvement from baseline (with baseline score ≥4), and percentage change in total EASI from baseline. Data from patients who received topical or systemic rescue medication or discontinued treatment due to lack of efficacy were imputed as nonresponders or set to baseline values. Data from patients who discontinued treatment for other reasons were set to missing and analyzed by multiple imputation. This was a post-hoc analysis conducted on the modified, pooled intent-to-treat population. Treatment-by-age subgroup interaction was assessed with logistic regression. Binary outcomes were analyzed by the Cochran-Mantel-Haenszel method, and continuous outcomes were analyzed with ANCOVA. Results At baseline, the numbers of patients treated with lebrikizumab and placebo, respectively, were 215 and 117 in the ≤2 years AD-onset subgroup, 178 and 103 in the >2-to-<18 years subgroup, and 171 and 67 in the ≥18 years subgroup. At baseline, the percentages of patients with ≥1 atopic comorbidity were 81% in the ≤2 years subgroup, 74% in the >2-to-<18 years subgroup, and 58% in the ≥18 years subgroup. At Week 16, treatment-by-age subgroup interactions were not significant at the 0.10 level for IGA 0,1; EASI 75; EASI 90; and Pruritus NRS 4-pt improvement. Within each subgroup, a higher proportion of lebrikizumab-treated compared with placebo-treated patients (p<0.001) achieved IGA 0,1 responses (≤2 years: 41% vs. 12%; >2-to-<18 years: 35% vs. 12%; ≥18 years: 38% vs. 12%), EASI 75 responses (≤2 years: 57% vs. 17%; >2-to-<18 years: 51% vs. 16%; ≥18 years: 58% vs. 20%), and EASI 90 responses (≤2 years: 38% vs. 10%; >2-to-<18 years: 32% vs. 9%; ≥18 years: 33% vs. 8%). Additionally, the least-squares mean percentage change from baseline in total EASI score for lebrikizumab and placebo, respectively, was -65% and -26% in the ≤2 years subgroup, -60% and -26% in the >2-to-<18 years subgroup, and -63% and -30% in the ≥18 years subgroup (p<0.001 for lebrikizumab vs. placebo in all subgroups). The proportion of lebrikizumab-treated patients who reported ≥4-point improvement in Pruritus NRS from baseline (baseline ≥4) was greater compared with placebo-treated patients ([N]; ≤2 years: 43% [201] vs. 11% [108]; >2-to-<18 years: 41% [161] vs. 14% [96]; ≥18 years: 45% [154] vs. 12% [60]; p<0.001). Conclusions Regardless of age of AD onset, lebrikizumab was associated with significant improvements in AD signs and symptoms compared with placebo over 16 weeks of treatment. [ABSTRACT FROM AUTHOR]

Introduction The decision to initiate systemic therapy (ST) in patients with atopic dermatitis (AD) is complex, with no criteria that are globally agreed upon. To aid dermatology providers in this decision-making, the "When to Start Systemic Therapy Checklist" was developed. The checklist comprises three components: (A) clinical severity, (B) subjective burden, and (C) lack of treatment response, each with several criteria. Systemic therapy is indicated when at least one criterion in each component is fulfilled. Objectives To corroborate the validity of this checklist, we evaluated the agreement between the decision to initiate ST using the checklist, against the reference, CorEvitas AD Registry patients prescribed a ST. Methods Adults with moderate-to-severe AD from the prospective, longitudinal CorEvitas AD registry were included in this descriptive analysis (July 2020 – August 2023). Patients were included if they were initiating ST at enrollment (ST group) or not initiating ST at enrollment (non-ST group) but had vIGA-AD® ≥3 and Eczema Area Severity Index ≥12. The checklist criteria were compared against registry outcome measures; when a criterion did not match a measure, either a proxy measure was selected or that part of the questionnaire was excluded. Overall percentage agreement (accord between checklist criteria and ST initiation status [reference standard]) with corresponding 95% confidence intervals (CIs) was calculated. Results In the ST group (n=1488), 97.0% of patients met at least one criterion from section A, 94.1% from section B, and 92.1% for either section A or B. In the non-ST group (n=208), 100% of patients met at least one criterion from section A, 92.3% from section B, and 92.3% from either section A or B. Among patients in the ST group who met at least one criterion each from section A and B, overall percentage agreement was 81.7% (95% CI: 79.8%, 83.5%). Section C, which addresses "lack of treatment response" could not be evaluated due to the absence of relevant data in the registry. Conclusions Nearly all patients initiating ST met at least one criterion from both section A and B of the "When to Start Systemic Therapy Checklist", demonstrating a strong alignment between the checklist sections A and B and disease burden of AD patients in the registry. Subsequent research is needed to assess section C due to registry limitations. Future analyses should examine why some patients with high disease burden and severity remain untreated with systemics.

The article discusses the results of two phase III clinical trials, ADvocate1 and ADvocate2, which examined the efficacy and safety of lebrikizumab monotherapy in patients with moderate-to-severe atopic dermatitis (AD). The trials found that lebrikizumab significantly improved patient-reported itch and reduced sleep loss due to itch. The improvements in itch and sleep loss were observed as early as the first few days of treatment and were consistent with previous studies on lebrikizumab. The study was funded by Dermira, a subsidiary of Eli Lilly and Company, and medical writing assistance was provided by ProScribe–Envision Pharma Group. [Extracted from the article]

Introduction: This real-world, cross-sectional study compared sociodemographic, clinical and treatment characteristics, and patient-reported outcomes (PROs) among racial/ethnic groups in patients with atopic dermatitis (AD) who are candidates for systemic therapy. Methods: This study included adults with dermatologist- or dermatology practitioner-diagnosed AD enrolled in the CorEvitas AD Registry (July 2020–July 2021). All patients initiated systemic therapy within 12 months prior to or at enrollment or had moderate-to-severe AD (vIGA-AD® ≥ 3 and Eczema Area and Severity Index [EASI] ≥ 12) at enrollment. Patients were categorized into five mutually exclusive racial/ethnic groups: non-Hispanic White, Black, Asian, Other/Multiracial, and Hispanic (any race). Patient, clinical, and treatment characteristics were captured at enrollment. Differences in means or proportions of characteristics among racial/ethnic groups were descriptively summarized using effect sizes. Adjusted prevalence ratios and mean differences were estimated (White race/ethnicity group as the reference category) with 95% confidence intervals (CI). Results: Among 1288 patients, 64% (n = 822) were White, 13% (n = 167) Black, 10% (n = 129) Asian, 8% (n = 97) Hispanic, and 6% (n = 73) Other/Multiracial. In adjusted analyses, statistically more severe EASI lichenification was noted among Black compared with White patients at the head and neck (mean difference, 0.21, [95% CI 0.06, 0.36]; p = 0.01), trunk (0.32, [0.17, 0.47]; p < 0.001), upper extremities (0.27, [0.09, 0.44]; p = 0.008), and lower extremities (0.39, [0.21, 0.57]; p < 0.001). Statistically more severe EASI lichenification was observed among Asian vs White patients in certain areas (mean difference, head and neck, 0.22 [0.04, 0.39], p = 0.01; trunk, 0.25 [0.07, 0.43], p < 0.001; lower extremities, 0.22 [0.01, 0.43], p < 0.001) and SCORing for AD lichenification (mean difference: 0.34 [0.15, 0.52]; p < 0.001). Significantly higher mean pruritus over the past 7 days for Black (mean difference: 0.63 [0.01, 1.26] and Hispanic patients (0.60 [0.11, 1.09]; p = 0.03) vs White patients was observed. Among AD clinical features, the prevalence of facial erythema was significantly lower among Black compared with White patients (prevalence ratio = 0.38, [0.22, 0.67]; p = 0.007). Conclusion: Racial/ethnic differences exist in sociodemographic, clinical and treatment characteristics, disease severity, and PROs among real-world AD patients who are candidates for systemic therapy. Recognizing these variations may be of critical importance for dermatologists for the design and delivery of targeted/personalized medicine approaches. [ABSTRACT FROM AUTHOR]

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disorder with limited treatment options for adolescents with moderate-to-severe disease. Lebrikizumab, a monoclonal antibody targeting interleukin (IL)-13, demonstrated clinical benefit in previous Phase 3 trials: ADvocate1 (NCT04146363), ADvocate2 (NCT04178967), and ADhere (NCT04250337). We report 52-week safety and efficacy outcomes from ADore (NCT04250350), a Phase 3, open-label study of lebrikizumab in adolescent patients with moderate-to-severe AD. The primary endpoint was to describe the proportion of patients who discontinued from study treatment because of adverse events (AEs) through the last treatment visit. Methods: Adolescent patients (N = 206) (≥ 12 to < 18 years old, weighing ≥ 40 kg) with moderate-to-severe AD received subcutaneous lebrikizumab 500 mg loading doses at baseline and Week 2, followed by 250 mg every 2 weeks (Q2W) thereafter. Safety was monitored using reported AEs, AEs leading to treatment discontinuation, vital signs, growth assessments, and laboratory testing. Efficacy analyses included Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Body Surface Area (BSA), (Children's) Dermatology Life Quality Index ((C)DLQI), and Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, and PROMIS Depression. Results: 172 patients completed the treatment period. Low frequencies of SAEs (n = 5, 2.4%) and AEs leading to treatment discontinuation (n = 5, 2.4%) were reported. Overall, 134 patients (65%) reported at least one treatment-emergent AE (TEAE), most being mild or moderate in severity. In total, 62.6% achieved IGA (0,1) with ≥ 2-point improvement from baseline and 81.9% achieved EASI-75 by Week 52. The EASI mean percentage improvement from baseline to Week 52 was 86.0%. Mean BSA at baseline was 45.4%, decreasing to 8.4% by Week 52. Improvements in mean change from baseline (CFB) to Week 52 were observed in DLQI (baseline 12.3; CFB − 8.9), CDLQI (baseline 10.1; CFB − 6.5), PROMIS Anxiety (baseline 51.5; CFB − 6.3), and PROMIS Depression (baseline 49.3; CFB − 3.4) scores. Conclusions: Lebrikizumab 250 mg Q2W had a safety profile consistent with previous trials and significantly improved AD symptoms and quality of life, with meaningful responses at Week 16 increasing by Week 52. Trial registration: ClinicalTrials.gov identifier, NCT04250350. Plain Language Summary: Lebrikizumab in Adolescent Patients with Moderate-to-Severe Atopic Dermatitis Atopic dermatitis is a chronic relapsing inflammatory skin disease that affects up to 15% of adolescents worldwide, with up to 50% suffering from moderate-to-severe disease. Signs and symptoms include dry, cracked skin; redness; itching; and painful lesions, which can negatively affect quality of life and lead to complications, including skin infections. Adolescents also report increased rates of anxiety and stress. Lebrikizumab is a novel monoclonal antibody that binds with high affinity and slow off-rate to interleukin (IL)-13, the key cytokine in atopic dermatitis, blocking the downstream effects of IL-13 with high potency. Lebrikizumab has been shown previously to improve symptoms of atopic dermatitis, including itch, skin clearance, and quality of life in ADvocate1, ADvocate2 and ADhere. The ADore study aimed to evaluate the safety and efficacy of lebrikizumab in adolescents with moderate-to-severe atopic dermatitis. Investigators recruited patients ≥ 12 to < 18 years old, weighing ≥ 40 kg, from Australia, Canada, Poland, and the US who were diagnosed with moderate-to-severe atopic dermatitis. These patients received a loading dose of 500 mg of lebrikizumab at Weeks 0 and 2, followed by 250 mg every 2 weeks for 52 weeks. The safety profile of lebrikizumab was consistent with previously published reports, with mostly mild or moderate adverse events, which did not lead to treatment discontinuation. Lebrikizumab improved skin clearance; 62.6% of patients had clear or almost clear skin by the end of the trial. Lebrikizumab also improved the patients' quality of life. These safety and efficacy results support lebrikizumab's role in treating adolescents with moderate-to-severe atopic dermatitis.

Introduction: The physical impact of alopecia areata (AA) is visible, but the psychological and social consequences and emotional burden are often underrecognized. Methods: In this cross-sectional study, 547 participants recruited via the National Alopecia Areata Foundation completed a survey encompassing demographics; AA illness characteristics; and five patient-reported outcome measures on anxiety and depression, perceived stress, psychological illness impact, stigma, and quality of life (QoL). Differences in disease severity subgroups were assessed via analysis of variance (ANOVA) and t tests. Results: Mean age was 44.6 years, and 76.6% were female. Participants with more severe hair loss tended to report longer duration of experiencing AA symptoms (P < 0.001). Overall, participants reported negative psychological impact, emotional burden, and poor QoL due to AA. Participants with 21–49% or 50–94% scalp hair loss reported greater psychological impact and poorer QoL than those with 95–100% scalp hair loss (most parameters P < 0.05). Similar results were observed for eyebrow/eyelash involvement subgroups. Conclusions: These results suggest that participants with AA experience emotional burden, negative self-perception, and stigma, but the impact of AA is not dependent solely on the amount of hair loss. Lower impact among participants with 95–100% scalp hair loss may indicate that they have adapted to living with AA. [ABSTRACT FROM AUTHOR]

Introduction/Background There is evidence of disparities in healthcare utilization for patients with atopic dermatitis (AD), but research exploring differences in patient treatment satisfaction and patient perception of interactions with their AD healthcare provider (HCP) by race and ethnicity is limited. Objectives The primary study objectives were to understand racial and ethnic differences in adult patients with AD for treatment use, treatment satisfaction, and patient perceptions on HCP interactions. Methods Adult patients living with self-reported AD in the United States (US) were recruited through the National Eczema Association (NEA) and the AmeriSpeak panel, a national sample of US adults. Sampling targets were used to achieve condition-based population proportions across multiple racial and ethnic categories. Patients completed an 80- to 110-item electronic one-time survey including questions on overall AD severity over the last month, current AD treatment, current AD treatment satisfaction, AD provider type, and perceptions of their interactions with HCPs. Data are reported using descriptive statistics. Results Overall, 260 patients (NEA n=18; AmeriSpeak n=242) completed the survey (mean age 40.6 years; 66.2% female; 55.0% White, 23.5% Black/African American, 11.5% Asian, and 10.0% American Indian/Alaskan Native, Native Hawaiian or Other Pacific Islander, or multiple-races (i.e. other races (OtR)); 13.5% Hispanic/Latino). Nearly half (49.6%) reported severity as mild, 43.1% moderate, and 7.3% severe. Overall, 63.8% of patients were using over-the-counter ointments/creams/lotions/gels for their AD, while 62.6% were using prescription creams/lotions. 28.2% reported being dissatisfied/very dissatisfied with their current treatment regimen, with treatment dissatisfaction was highest among Black/African American patients (36.2%) and lowest among OtR patients (21.7%). Additionally, 22.6% of patients reported that in the past year they or a household member had been unable to get medicine or any healthcare (medical, dental, mental health, vision); this was reported by 32.2% Black/African American, 21.1% White, 19.2% OtR, 13.3% Asian, 20.0% Hispanic/Latino, and 23.0% Non-Hispanic/Non-Latino. 49.2% indicated that a dermatologist was the provider they primarily saw for medications to treat their AD. This was followed by primary care providers (33.1%), those who did not see a provider for their AD (10.4%), and allergists (4.2%). Of those who indicated they saw a provider for their AD, 39.1% of patients report their HCP listened to their AD concerns 'somewhat' or 'a little bit'; Asian (61.6%), White (38.9%), Black/African American (32.7%), and OtR (30.4%). 43.3% of Hispanic/Latino and 38.5% of Non-Hispanic/Non-Latino patients reported their HCP listened 'somewhat' or 'a little bit.' Only 1.3% of all patients reported their HCPs did not listen to their concerns 'at all.' When asked how much they thought their AD HCP understood their perspective on their AD, 42.4% of all patients chose 'somewhat' or 'a little bit.' This was reported by 46.2% Asian patients, 44.4% White patients, 41.7% OtR patients, 36.4% Black/African American patients, 53.1% Hispanic/Latino patients, and 40.7% Non-Hispanic/Non-Latino patients. Additionally, 42.1% of all patients reported they 'somewhat' or 'a little bit' trust that their HCP effectively treats their AD. This was reported by 50.0% Asian patients, 45.3% White patients, 34.6% Black/African American patients, 33.3% OtR patients, 43.8% Hispanic/Latino patients, and 41.8% Non-Hispanic/Non-Latino patients. Overall, 3% of patients reported they did not trust their HCP to effectively treat their AD 'at all' and 1.3% reported their HCPs did not understand their perspective 'at all.' Conclusions Nearly a quarter of patients living with AD reported not being able to access medicine or healthcare in the past year. Although there were differences in the percentages reported by race and ethnicity, some patients indicated there were gaps with regards to the patient-physician relationship around not feeling completely listened to, understood, or trusting HCPs treating AD. These findings may help inform clinical practice considerations in AD. [ABSTRACT FROM AUTHOR]

Introduction/Background Lebrikizumab is a novel, high-affinity monoclonal antibody, selectively targeting IL-13 with a slow dissociation rate. The efficacy and safety of lebrikizumab to treat moderate-to-severe atopic dermatitis (AD) have been established in phase 3 studies, including subset analyses by race and ethnicity. ADmirable (NCT05372419) is the first phase 3b, open-label, 24-week study to evaluate the efficacy and safety of lebrikizumab in adult and adolescent patients with moderate-to-severe AD and skin of color (SOC). Objectives To present the baseline demographics, clinical characteristics, and 16-week efficacy from an interim analysis of ADmirable. Methods Patients who enrolled by June 29, 2023, and completed 16 weeks of lebrikizumab treatment or discontinued treatment on or prior to Week 16 were included in this analysis. At baseline and Week 2, patients received a 500-mg lebrikizumab loading dose followed by 250 mg every 2 weeks through Week 16. Key eligibility criteria included: ≥12 years of age (≥40 kg for adolescents), self-reported race other than White, Fitzpatrick Phototype IV-VI, chronic AD present for ≥1 year, history of inadequate response to topical medications, naïve to biologics indicated for AD treatment, baseline Eczema Area and Severity Index (EASI) ≥16, Investigator's Global Assessment (IGA) ≥3, and ≥10% body surface area (BSA) of AD involvement. Baseline demographics and clinical characteristics were collected during screening. Efficacy endpoints included the proportion of patients achieving ≥75%/≥90% reduction in EASI (EASI 75/90); IGA of 0,1 with ≥2-point improvement from baseline (IGA 0,1) and ≥3-point and ≥4-point Pruritus Numeric Rating Scale (NRS) improvement from baseline; mean percentage change in EASI and Pruritus NRS; and changes in post-inflammatory hyperpigmented (PIH) lesions as measured by PDCA-Derm™, a new scale comparing PIH lesions with unaffected, adjacent normal skin. Serious adverse events (SAEs) were also assessed. Additional innovative objective measures of pigment and erythema were utilized in this trial. Discrete variables are described using frequencies and percentages, and continuous variables are described with summary statistics. All data are as observed. Results The analysis included 50 enrolled patients. Forty patients (80%) were Black/African-American, 7 (14%) were Asian, and 3 (6%) were American Indian/Alaska Native; 11 (22%) were Hispanic/Latino and 39 (78%) were not Hispanic/Latino; 8 (16%) patients were adolescents and 23 (46%) patients were female. The proportions of patients with Fitzpatrick Phototype IV, V, and VI were 42%, 22%, and 36%, respectively. At baseline, mean (SD) age was 42.2 (19.7) years; and disease duration was 19.3 (15.8) years. Mean (SD) baseline BMI was 30.2 (7.7) kg/m2. Mean (SD) BSA affected was 41.7% (20.8) and 64% of patients presented with IGA=3. At baseline, mean (SD) EASI and Pruritus NRS were 28.1 (12.4) and 7.2 (2.2), respectively, and 27 patients (54%) had at least one PIH lesion. Clinical characteristics included AD with prurigo nodules (16%), follicular/perifollicular accentuation of AD (14%), allergic shiners (12%), pityriasis alba (10%), and AD with nummular features (10%). 40 patients completed the Week-16 visit. At Week 16, the proportions of patients achieving the following outcomes were: EASI 75: 68%; EASI 90: 46%; IGA 0,1: 39%; ≥3-Point Pruritus NRS improvement: 66%; and ≥4-point Pruritus NRS improvement: 56%. At Week 16, the mean percentage change from baseline (improvement) was -79.1% for EASI and -53.9% for Pruritus NRS. At Week 16, 12 of 21 patients with baseline hyperpigmented lesions had improved PDCA-Derm™ and 6 of the 21 lesions achieved normal skin tone. No SAEs were observed. Conclusions In this interim analysis of the first Phase 3b clinical trial of lebrikizumab for patients with moderate-to-severe AD and SOC, lebrikizumab improved AD signs and symptoms as measured with objective and subjective tools and scales, and no SAEs were observed.

Introduction/Background Lebrikizumab (LEB) is a novel monoclonal antibody that binds with high affinity and slow off-rate to interleukin (IL)-13, thereby blocking the downstream effects of IL-13 with high potency. ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967) are identically designed Phase 3 trials that evaluated LEB as a monotherapy treatment for moderate-to-severe atopic dermatitis (AD). Many patients who met the protocol-defined response criteria at Week 16, defined as achieving ≥75% improvement in the Eczema Area and Severity Index (EASI 75) or an Investigator's Global Assessment of 0 or 1 (IGA 0/1) without use of rescue therapy, maintained a deep response up to Week 521. Deep response was defined as maintaining an IGA 0 (clear skin), a 100% improvement in the Eczema Area and Severity Index (EASI 100), or a Pruritus Numeric Rating Scale score of 0 or 1 (Pruritus NRS 0/1). Patients completing Week 52 were given the option to roll over into a long-term extension (LTE) study, ADjoin (NCT04392154), allowing the opportunity to analyze deep response for a longer period of time. This analysis supports the evolution of AD treatment goals toward maintaining higher efficacy thresholds for a longer duration. Objectives To present the long-term maintenance of LEB's depth of response for up to 104 weeks of treatment (52 weeks in the ADvocate studies and 52 weeks in the ADjoin study). Methods Patients entering ADjoin from ADvocate1 and ADvocate2 continued taking the same LEB dose as the parent study. Patients receiving placebo (LEB withdrawal) during the maintenance period of ADvocate1 and ADvocate2 transitioned to receive LEB every 2 weeks (Q2W) during ADjoin (data not included in this analysis). The proportion of patients achieving IGA and EASI responses were calculated from the LEB-treated patients who were IGA 0/1 or EASI 75 responders, respectively, at Week 16 in ADvocate1 and ADvocate2. The proportion of patients achieving a Pruritus NRS 0/1 response were calculated from the LEB patients who were per protocol responders at Week 16 of ADvocate1 and ADvocate2. Each patient's absolute Pruritus NRS score was calculated by averaging daily scores from the previous seven days with at least one nonmissing value. The weekly score was then rounded to the nearest integer. Consistent with common reporting practices for LTE studies, this post hoc analysis reports observed data which were analyzed regardless of rescue medication use or treatment discontinuation. Results From Week 52 to Week 104, the proportion of IGA 0 responders was maintained and slightly increased in patients treated with LEB Q2W (50.8% [N=59] to 52.3% [N=44]) and LEB every 4 weeks (Q4W; 43.5% [N=69] to 45.5% [N=55]). Greater improvements over the second year of treatment were seen in the proportion of EASI 100 responders treated with LEB Q2W (36.4% [N=88] to 39.7% [N=68]) and LEB Q4W (30.7% [N=101] to 41.3% [N=80]) as well as the proportion of Pruritus NRS 0/1 responders treated with LEB Q2W (46.3% [N=80] to 57.4% [N=61]) and Q4W (47.9% [N=94] to 55.4% [N=65]). Although rescue medication was allowed during ADjoin, a relatively low proportion of patients received ≥1 topical rescue medication in the LEB Q2W (9.8%) and LEB Q4W (15.2%) treatment arms. Conclusions These 2-year results demonstrate an extended maintenance of deep response in patients treated with LEB Q2W and LEB Q4W after responding to 16 weeks of LEB Q2W. Approximately 50% and 40% of LEB-treated patients sustained total skin clearance (IGA 0 and EASI 100, respectively) and more than 55% of LEB-treated patients reported no or minimal itch (Pruritus NRS 0/1). Maintenance treatment with LEB Q2W and LEB Q4W allows patients and providers to elevate their expected treatment goals in AD beyond EASI 75 and IGA 0/1 response. [ABSTRACT FROM AUTHOR]

Introduction Historically, atopic dermatitis (AD) was believed to affect primarily children. However, a recent meta-analysis of 17 studies reporting age of AD onset as >16 years found that the pooled proportion of adult-onset AD was 26.1%, and that AD onset can occur at all ages. Lebrikizumab (LEB) is a high-affinity monoclonal antibody which targets IL-13, the key cytokine implicated in AD. Objectives This analysis investigated the efficacy and safety of lebrikizumab in adults ≥60 years with moderate-to-severe AD. Methods Data for patients aged ≥60 years from two Phase 3 trials, ADvocate1 and ADvocate2, were pooled. A total of 98 patients ≥ 60 years participated in the ADvocate trials (N=28 placebo (PBO), N=70 LEB). Patients were treated with lebrikizumab 250mg every 2 weeks or PBO, for 16 Weeks. Baseline demographics and characteristics were recorded. Efficacy was assessed in the pooled modified intent to treat population at Week 16 with Investigator's Global Assessment (IGA) (0,1) with ≥2-point improvement, ≥75% improvement in Eczema Area and Severity Index (EASI 75), EASI percentage change from baseline (CFB), and Pruritus Numeric Rating Scale (NRS) ≥4-point improvement. Categorical outcomes were evaluated by Cochran Mantel Haenszel tests to compare treatment groups. Continuous outcomes were analyzed using the analysis of covariance model. Data collected after use of rescue medication or discontinuation due to lack of efficacy were imputed with non-responder imputation (NRI) for categorical endpoints, or baseline values for continuous endpoints. Data collected after discontinuation for other reasons were set to missing and missing data were imputed with multiple imputation. Safety was also assessed in the integrated modified safety population. Results The baseline mean age was 67.2 years (standard deviation [SD] 6.7, range 60-93) in LEB- treated patients and 69 years ([6.2], range 60-85) in PBO. The LEB-treated population was 62.9% male (n=44/70) vs PBO 46.4% (n=13/28). Race was comparable between groups. At baseline 67.1% LEB (n=47/70) and 57.1% PBO (n=16/28) patients had IGA 3, while 32.9% LEB (n=23/70) and 42.9% PBO (n=12/28) had IGA 4. Other baseline characteristics were comparable: EASI: LEB 26.1, [10.6] vs PBO 27.1, [8.1]; BSA: LEB 38.3, [19.8] vs. PBO 40.9, [18.1]; and Pruritus NRS: LEB 7.5, [2.0] vs PBO 7.4, [1.7]. At Week 16, IGA (0,1) was achieved by 34.5% LEB-treated patients vs 11% PBO (P=0.022). EASI 75 was achieved by 48.9% and 16.3% of LEB- and PBO-treated patients, respectively (P=0.004). Pruritus NRS with ≥4-point improvement was reported by 45.5% and 12.2% of LEB vs PBO, respectively (P=0.004). The mean percent CFB EASI was LEB -58.5% (SE 8.5) and PBO -29.4% (SE 11.1) (P=0.002). Safety results in the older adult population were consistent with the overall modified safety population. Conclusions At Week 16, efficacy and patient reported outcome endpoints were met in the older adult population. These results indicate that lebrikizumab is an effective treatment for moderate-to-severe AD in the adult population ≥60 years of age and has a consistent safety profile. [ABSTRACT FROM AUTHOR]

Background Lebrikizumab is a novel, high-affinity monoclonal antibody that selectively binds to interleukin (IL)-13. Objectives To evaluate the efficacy and safety of lebrikizumab monotherapy in adolescent and adult patients with moderate-to-severe atopic dermatitis (AD) over 52 weeks of treatment in ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967). Methods Patients who responded to lebrikizumab 250 mg every 2 weeks (Q2W) at the end of the 16-week induction period were re-randomized 2 : 2 : 1 to receive lebrikizumab Q2W, lebrikizumab 250 mg every 4 weeks (Q4W) or placebo Q2W (lebrikizumab withdrawal) for 36 additional weeks. Response at week 16 was defined as achieving a 75% reduction in Eczema Area Severity Index (EASI 75) or an Investigator's Global Assessment (IGA) of 0 or 1, with a ≥ 2-point improvement and no rescue medication use. Multiple imputation was used to handle missing data. Intermittent use of topical therapy was permitted during the maintenance period. Results After 52 weeks, an IGA of 0 or 1 with a ≥ 2 point improvement was maintained by 71.2% of patients treated with lebrikizumab Q2W, 76.9% of patients treated with lebrikizumab Q4W and 47.9% of patients in the lebrikizumab withdrawal arm. EASI 75 was maintained by 78.4% of patients treated with lebrikizumab Q2W, 81.7% of patients treated with lebrikizumab Q4W and 66.4% of patients in the lebrikizumab withdrawal arm at week 52. Across treatment arms, proportions of patients using any rescue therapy were 14.0% (ADvocate1) and 16.4% (ADvocate2). During the combined induction and maintenance periods of ADvocate1 and ADvocate2, 63.0% of lebrikizumab-treated patients reported any treatment emergent adverse event, with most events (93.1%) being mild or moderate in severity. Conclusions After a 16-week induction period with lebrikizumab Q2W, lebrikizumab Q2W and Q4W maintained similar improvement of the signs and symptoms of moderate-to-severe AD, with a safety profile consistent with previously published data.

Background: Baricitinib demonstrated efficacy in treating adults with moderate‐to‐severe atopic dermatitis (AD) in Phase 3 clinical trials. Objective: To examine long‐term efficacy of baricitinib combined with topical corticosteroids (TCS) in adult patients from a Phase 3 study, BREEZE‐AD7 (NCT03733301), enrolled in ongoing extension study, BREEZE‐AD3 (NCT03334435). Methods: Upon BREEZE‐AD7 completion, responders or partial responders (RPR [vIGA‐AD™ ≤2]) receiving baricitinib 2‐mg or 4‐mg + TCS maintained their original treatment doses in BREEZE‐AD3. Nonresponders (NR; vIGA‐AD 3,4) receiving baricitinib 2‐mg were rerandomized 1:1 to baricitinib 2‐mg or 4‐mg; NR receiving baricitinib 4‐mg remained on same dose. Integrated data from all patients (RPR + NR = baricitinib 4‐mg intent‐to‐treat [ITT] cohort) receiving continuous baricitinib 4‐mg in BREEZE‐AD7 through BREEZE‐AD3 were analysed, along with baricitinib 4‐mg or 2‐mg RPR cohorts. Primary endpoint was proportion of patients with vIGA‐AD (0,1) at Weeks 16, 36 and 52 (Weeks 32, 52 and 68 of continuous therapy). Additional outcomes included improvement in EASI75 and Itch NRS (up to Week 32). Missing data were imputed by last observation carried forward. Results: In baricitinib 4‐mg ITT cohort (N = 102), proportions of patients achieving vIGA‐AD (0,1) at Week 32, Week 52, and Week 68 were 21.6%, 26.5% and 23.5%; EASI75 were 46.1%, 40.2% and 43.1%, respectively. Itch NRS ≥4‐point improvement (Itch ≥4) were 47.3% at Week 16 and 40.6% at Week 32. In baricitinib 4‐mg RPR cohort (N = 63), proportions of patients achieving vIGA‐AD (0,1) at Week 32, Week 52 and Week 68 were 31.7%, 33.3% 34.9%, respectively; EASI75 were 57.1%, 49.2% and 49.2%, respectively. Itch ≥4 were 53.6% at Week 16 and 46.4% at Week 32. Corresponding proportions for baricitinib 2‐mg RPR cohort (N = 53) for vIGA‐AD (0,1) were 39.6%, 45.3% and 30.2%; EASI75 were 77.4%, 69.8% and 58.5%, respectively. Itch ≥4 were 56.3% at Week 16 and 47.9% at Week 32. Conclusion: Baricitinib 4‐mg and 2‐mg combined with TCS maintained clinically meaningful sustained efficacy over 68 weeks of continuous treatment.

Real-world data on the effectiveness of systemic therapy in atopic dermatitis (AD) are limited. Adult patients with AD in the CorEvitas AD registry (2020–2021) who received systemic therapies for 4–12 months prior to enrollment were included based on disease severity: body surface area (BSA) 0%–9% and BSA ≥10%. Demographics, clinical characteristics, and outcomes were assessed using descriptive statistics. Pairwise effect sizes (ES) were used to compare BSA groups. The study included 308 patients (BSA 0%–9%: 246 [80%]; BSA ≥10%: 62 [20%]). Despite systemic therapy, both BSA groups reported the use of additional topical therapy and the presence of lesions at difficult locations. Moderate-to-severe AD (vIGA-AD®) was reported by 11% (BSA 0%–9%) and 66% (BSA ≥10%; ES = 0.56) of patients. Mean disease severity scores: total BSA (2% and 22%; ES = 3.59), EASI (1.1 and 11.1; ES = 2.60), and SCORAD (12.1 and 38.0; ES = 1.99). Mean scores for PROs: DLQI (3.7 and 7.5; ES = 0.75), and peak pruritus (2.2 and 4.5; ES = 0.81). Inadequate control of AD was seen in 27% and 53% of patients (ES = 0.23). Patients with AD experience a high disease burden despite systemic treatment for 4–12 months. This study provides potential evidence of suboptimal treatment and the need for additional effective treatment options for AD. This real-world study assessed clinical characteristics and overall disease burden in adult patients with atopic dermatitis (AD) who were receiving systemic therapy for 4–12 months. Patients reported greater involvement of back and anterior trunk, and lesions at difficult locations. Irrespective of body surface area involvement, patients continued to experience inadequate control of AD, varied disease severity, and impact on quality of life. The study provides potential evidence of suboptimal treatment and the need for effective treatment options for the management of AD. Besides clinical outcomes, treating dermatologists and dermatology practitioners should include patient-reported outcomes in routine clinical care to determine the best treatment options for their patients.

This post hoc analysis assessed association between scalp hair regrowth and improvements in health-related quality of life (HRQoL) and psychological burden in patients with severe alopecia areata (AA). Data were pooled from two phase-3 trials (N = 1200). Patients randomized to once-daily placebo, baricitinib 2-mg, or 4-mg were analyzed independently of treatment allocation, and categorized according to scalp hair regrowth (at Week 36): meaningful regrowth (Severity of Alopecia Tool (SALT) score ≤20); intermediate regrowth (≥30% SALT improvement [SALT30] at any post-baseline visit to Week 36, but SALT score > 20 at Week 36); no/minimal regrowth (never achieved SALT30). Skindex-16 for AA score change-from-baseline and proportion of patients with baseline Hospital Anxiety and Depression Scale (HADS) scores ≥8 that shifted to <8 (normal) were assessed. Patients with meaningful regrowth achieved greater improvements in all Skindex-16 AA domains versus no/minimal regrowth. More patients with meaningful versus no/minimal regrowth shifted from HADS ≥8 to <8 (anxiety:46.8% versus 26.4%; depression:52.3% versus 24.0%). Improvements occurred with intermediate regrowth but to a lesser extent versus meaningful regrowth. Patients with severe AA and scalp hair regrowth at Week 36 experienced greater improvements in HRQoL and anxiety and depression versus patients with no/minimal regrowth. The highest benefit was observed in patients with meaningful regrowth (SALT score ≤20).ClinicalTrials.gov listing: NCT03570749 and NCT03899259 [ABSTRACT FROM AUTHOR]

Patients with atopic dermatitis (AD) have low treatment satisfaction. In this study, we evaluated the humanistic burden, treatment satisfaction, and treatment expectations in patients with AD in the United States. Adults with AD recruited through the National Eczema Association and clinical sites completed a web-based survey comprising the Patient-Oriented SCORing Atopic Dermatitis (PO-SCORAD), Dermatology Life Quality Index; Work Productivity and Activity Impairment Questionnaire-Atopic Dermatitis; Treatment Satisfaction Questionnaire for Medication (TSQM); and answered questions on healthcare provider (HCP) visits, treatment history, and treatment goals. Descriptive analyses were performed to compare participants by severity. Among 186 participants (mean [standard deviation] age 39.7 [15.3] years, 79.6% female), 26.9%, 44.6%, and 26.3% of the participants had mild, moderate, or severe AD, respectively, based on PO-SCORAD. Greater disease severity was associated with a greater impact on work and daily life, decreased TSQM scores, and increased HCP visits. Corticosteroid topical cream or ointment (53.8%) and oral antihistamines (31.2%) were most commonly used for the treatment of AD. Participants reported declining/stopping/changing AD treatment due to the potential for side effects or lack of efficacy. 'Leading normal lives' (28.0%) and 'being itch-free' (33.9%) were important treatment goals. Individuals with AD, especially severe disease, face a considerable humanistic burden even while using treatment. [ABSTRACT FROM AUTHOR]

Patients who completed the originating studies, BREEZE-AD1 (NCT03334396), BREEZE-AD2(NCT03334422), and BREEZE-AD7 (NCT03733301), were eligible for enrollment in the multicenter,phase-3, long-term extension study BREEZE-AD3 (NCT03334435). At week 52, responders and partial responders to baricitinib 4 mg were re-randomized (1:1) into the sub-study to dose continuation (4 mg, N = 84), or dose down-titration (2 mg, N = 84). Maintenance of response was assessed from week 52 to 104 of BREEZE-AD3. Physician-rated outcomes included vIGA-AD (0,1), EASI75, and mean change from baseline in EASI. Patient-reported outcomes included DLQI, P OEM total score, HADS, and from baseline: WPAI (presenteeism, absenteeism, overall work impairment, daily activity impairment) and change from baseline in SCORAD itch and sleep loss. With continuous treatment with baricitinib 4 mg, efficacy was maintained up to week 104 in vIGA-AD (0,1), EASI75, EASI mean change from baseline, SCORAD itch, SCORAD sleep loss, DLQI, P OEM, HADS, and WPAI (all scores). Patients down-titrated to 2 mg maintained most of their improvements in each of these measures. The sub-study of BREEZE AD3 supports flexibility in baricitinib dosing regimens. Patients who continued treatment with baricitinib 4 mg and down-titrated to 2 mg maintained improvements in skin, itch, sleep, and quality of life for up to 104 weeks. [ABSTRACT FROM AUTHOR]

To address the need for long‐term efficacy and patient‐reported outcomes (PROs) data for patients with atopic dermatitis (AD) treated with baricitinib 2 mg, a study was conducted to evaluate the efficacy of baricitinib 2 mg in adult patients with moderate‐to‐severe AD. Data presented here provided efficacy and outcomes data for patients treated for 52 weeks. Patients who participated in the originating study, BREEZE‐AD5 (NCT03435081), and met additional eligibility criteria could enroll in the multicenter, open‐label, Phase 3, long‐term extension study BREEZE‐AD6 (NCT03559270). Patients received baricitinib 2 mg for the duration of BREEZE‐AD6. In BREEZE‐AD6, the proportion of patients who achieved a 75% improvement in the Eczema Area and Severity Index (EASI75) and validated Investigator Global Assessment for AD (vIGA‐AD™) of 0 (clear) or 1 (almost clear) were assessed through 52 weeks, in addition to several PROs. At week 52, the proportion of patients treated with baricitinib 2 mg daily achieving EASI75 was 48.6% (70/144), and 31.3% (45/144) of patients achieved a vIGA‐AD score of 0 or 1 (clear or almost clear). Improvements in PROs such as SCORing Atopic Dermatitis (SCORAD, itch and sleep) scores, Dermatology Life Quality Index (DLQI) total score, and DLQI ≤5 response were observed, and these responses were sustained through 52 weeks. Long‐term efficacy of baricitinib in patients with AD was demonstrated by both clinician and patient‐reported outcome measures. [ABSTRACT FROM AUTHOR]

Background/Purpose To address issues regarding health disparities and differential access to health care in diverse racial and ethnic populations, many of whom are part of underserved communities, current and robust data on atopic dermatitis (AD) prevalence by race/ethnicity are needed. Whereas data on pediatric prevalence of atopic dermatitis in diverse race/ethnicity populations have been reported, there are limited epidemiologic data on adult populations with AD. Methods Analyses were conducted using cross-sectional data from the 2021 National Health Interview Survey. Weighted overall frequencies of subject reports of diagnosed AD or eczema were estimated by race/ethnicity. Adjusted odds ratios were estimated to compare prevalence rates between subgroups. Corresponding population denominators for use in estimating prevalence rates were obtained from the US Census Bureau (2020 Census Demographic Profile). Prevalence is reported as percentage (standard error). Pediatric data was also analyzed for the presentation. Results Overall US prevalence of AD in adults ages 18-64 was 7.6% (0.2) and age 65+ was 6.1% (0.3), with a weighted US estimate of 15.3 and 3.2 million respectively. Race/ethnicity prevalence rates for all adults were Black/African American 8.5% (0.6), White 7.7% (0.2), Asian 6.5% (0.7), American Indian/Alaskan Native 4.9% (2.1), and Hispanic 4.8% (0.4). The odds ratio for Hispanic vs Non-Hispanic White was 0.6 (95%CI 0.5-0.7; p<0.0001). Conclusions Total US prevalence of AD in all adults is approximately 18 million. Hispanic adults have a lower prevalence AD than all other adult groups. Additional studies are needed to understand sociodemographic variations in AD prevalence. [ABSTRACT FROM AUTHOR]

Dupilumab is a treatment option for moderate-to-severe atopic dermatitis (AD). Not all patients treated with dupilumab achieve and maintain clinically meaningful responses; some experience adverse events and some discontinue dupilumab for other reasons. For these patients, prospective data are needed to better understand the efficacy of systemic medications administered after discontinuation of dupilumab. Lebrikizumab (LEB) is a monoclonal antibody that binds with high affinity and slow off-rate to interleukin (IL)-13, thereby blocking the downstream effects of IL-13 with high potency. ADhere (NCT04250337) is a randomized, double-blind phase 3 trial evaluating the efficacy of lebrikizumab in combination with topical corticosteroids (TCS) over 16 weeks in adults and adolescents with moderate-to-severe AD. The results of this study, previously reported, showed statistically and clinically meaningful improvements in the signs and symptoms of AD in patients treated with LEB plus TCS vs. placebo (PBO) plus TCS. Of the patients randomized to LEB plus TCS, 20 reported prior dupilumab exposure. This study aims to evaluate the efficacy of LEB plus low to mid-potency TCS for the treatment of moderate-to-severe AD in the subpopulation of ADhere patients with prior exposure to dupilumab. At baseline, eligible patients in ADhere were randomized 2 : 1 to LEB 250 mg plus TCS or PBO plus TCS. Patients with prior exposure to dupilumab were permitted, with at least 8 weeks of washout prior to entering the study. Reported medical history was used to identify patients with prior exposure to dupilumab. Efficacy was measured through Investigator's Global Assessment (IGA), Eczema Area and Severity Index (EASI) and Pruritus Numeric Rating Scale (NRS). ADhere analyses were performed on a modified population, excluding 17 patients (from a single study site) whose eligibility could not be confirmed. All analyses are descriptive summaries using post hoc, as-observed analyses. The Pruritus NRS analysis only includes patients with baseline values ≥4. Observed results exclude data collected after use of rescue medication or treatment discontinuation. In ADhere, 211 patients were randomized 2 : 1 to LEB plus TCS (n = 145) or PBO plus TCS (n = 66). Of the patients randomized to LEB plus TCS, 20 reported prior dupilumab exposure. Of these 20 patients, the reason for dupilumab discontinuation was loss of response or inadequate response (10 patients), subject decision (four patients) or intolerance to medication (one patient). The final five patients discontinued due to affordability, treatment availability or unspecified reasons. In patients treated with LEB plus TCS, baseline disease characteristics were comparable between the overall LEB-treated population (n = 145) and the subpopulation with prior dupilumab exposure (n = 20). Of the 20 patients with prior dupilumab exposure, 13 patients presented with an IGA of three and seven patients presented with an IGA of 4. The mean [standard deviation (SD)] body surface area reported at baseline was 37.3 (15.7). The mean (SD) baseline scores for EASI and Pruritus NRS were 25.9 (8.1) and 7.8 (1.9), respectively. The mean (SD) duration since AD onset was longer in patients with prior dupilumab experience vs. the overall LEB-treated population 27.0 (22.5) vs. 21.0 (17.4) years, respectively]. In patients treated with LEB plus TCS, two of the 20 with prior dupilumab exposure were excluded due to use of rescue medication or treatment discontinuation. The IGA 0/1 with 2-point improvement was achieved by 6/18 patients, EASI 75 was achieved by 13/18 patients and Pruritus NRS 4-point improvement was achieved by 8/15 patients at Week 16. One patient reported rescue medication use. The results of this subpopulation analysis suggest that patients with prior dupilumab exposure can benefit from lebrikizumab treatment in combination with TCS. Additional data are needed to confirm this finding due to the small number of patients in the subpopulation. [ABSTRACT FROM AUTHOR]

Introduction/Background The efficacy of monotherapy lebrikizumab to treat moderate-to-severe atopic dermatitis (AD) has been established in phase 3 studies. Disease characteristics and efficacy outcomes may vary among racial and ethnic subgroups. Objectives: To report the week 16 efficacy results of lebrikizumab-treated patients by racial and ethnic subgroups from ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967). Methods: Eligible patients were randomized 2:1 to receive lebrikizumab or placebo every 2 weeks. Other AD treatments during this induction period were prohibited. The week 16 efficacy endpoints reported here include Investigator's Global Assessment 0 or 1 with =2-point improvement from baseline (IGA 0/1), =75% improvement in the Eczema Area and Severity Index from baseline (EASI 75), =90% improvement in EASI from baseline (EASI 90), and =4-point Pruritus Numeric Rating Scale (NRS) improvement from baseline. Race and ethnicity were self-reported. Data were collected globally. Data were pooled from ADvocate1 (Intent to Treat [ITT]) and ADvocate2 (modified ITT). Subsequent data from patients who received topical or systemic rescue medication or discontinued treatment due to lack of efficacy were imputed as nonresponders. Subsequent data from patients who discontinued treatment for other reasons were set to missing. Missing data were handled with multiple imputation. Logistic regression tested the interaction between the treatment by subgroup. P>0.1 indicated consistent treatment effect of lebrikizumab versus placebo across subgroups. For each outcome, the Cochran-Mantel-Haenszel method evaluated treatment effect within each subgroup after adjusting for stratification factors. Results: Most patients (818/851 [96.1%]) were Asian (192 [22.6%]), Black/African American (84 [9.9%]), or White (542 [63.7%]). Due to the low proportion of patients identifying as another racial category (33/851 [3.9%]) including American Indian or Alaska Native, Native Hawaiian or other Pacific Islander, multiple, other, and not reported, only results of Asian, Black/African American, and White subgroups are reported. In patients with completed ethnicity data (N=839), 10.8% (91/839) identified as Hispanic/Latino and 89.2% (748/839) identified as not Hispanic/Latino. At baseline, Asian patients reported a numerically earlier mean age of AD onset (8.3 years) compared to White (16.5 years) and Black/African American (16.9 years) patients. A numerically greater proportion of Asian patients presented with severe (IGA 4) disease at baseline (49.5%) and prior use of systemic treatment for AD (75.5%) compared with White (35.1% and 51.1%, respectively) and Black/African American (33.3% and 36.9%, respectively) patients. At week 16, no significant treatment differences were observed for the proportion of patients achieving or reporting IGA 0/1, EASI 75, EASI 90, or ≥4-point Pruritus NRS improvement across racial or ethnic subgroups (p>0.1). In Asian patients, a higher proportion treated with lebrikizumab vs placebo (p<0.001) achieved or reported IGA 0/1 (25.1%, 4.1%), EASI 75 (45.5%, 8.5%), EASI 90 (26.5%, 4.3%), and Pruritus NRS ≥4-point improvement (36.4%, 5.7%). In Black/African American patients, a greater proportion treated with lebrikizumab versus placebo achieved or reported IGA 0/1 (33.2%, 13.2%) EASI 75 (51.7%, 18.8%), EASI 90 (26.9%, 13.2%), and ≥4-point Pruritus NRS improvement (41.7%, 17.4%). No statistical comparisons were performed due to limited sample size. In White patients treated with lebrikizumab, statistical significance was observed versus placebo (p<0.001) for IGA 0/1 (43.3%, 14.1%), EASI 75 (59.7%, 20.4%), EASI 90 (38.3%, 10.9%), and Pruritus NRS ≥4-point improvement (45.9%, 14.8%). Significant and similar differences with lebrikizumab-treatment versus placebo were observed among IGA 0/1, EASI 75, and ≥4-point Pruritus NRS improvement in Hispanic/Latino (p<0.05) and non-Hispanic/Latino (p<0.001) patients. The proportion of lebrikizumab-treated patients achieving EASI 90 versus placebo was numerically greater in Hispanic/Latino patients (p=0.057) but only reached statistical significance in non-Hispanic/Latino patients (p<0.001). Conclusions: In ADvocate1 and ADvocate2, lebrikizumab was effective across racial and ethnic subgroups for the treatment of moderate-to-severe AD after 16 weeks of monotherapy treatment.

Introduction/Background Atopic dermatitis (AD) is a chronic disease affecting children and adults and requires long-term treatment. Moderate-to-severe AD causes itching, which considerably impacts sleep. Interleukin (IL)-13 is the key cytokine in the skin of patients with AD. Lebrikizumab (LEB) is a novel monoclonal antibody that binds with high affinity and slow off-rate to IL-13, thereby blocking the downstream effects of IL-13 with high potency. LEB has demonstrated efficacy and maintained improvement in measures of itch and sleep over 52 weeks in previous phase 3 trials. ADhere (NCT04250337) was a 16-week, randomized, double-blinded, placebo-controlled, phase 3 clinical trial, where patients were treated with LEB and topical corticosteroids (TCS) vs placebo and TCS. LEB responders from ADhere at week 16 were defined as having Investigator's Global Assessment response of 0 or 1 or reporting 75% improvement from ADhere baseline in Eczema Area and Severity Index who did not use rescue medications. ADhere LEB responders were rerandomized 2:1 into ADjoin (NCT04392154) for blinded treatment with LEB 250 mg every 2 weeks (Q2W) or every 4 weeks (Q4W), respectively, with TCS use as needed, for an additional 100 weeks with itch and sleep data being collected for the first 52 weeks. Objectives: The objectives of the study are to report the impact of LEB on itch and sleep improvements over a longer period (68 weeks) in ADhere week 16 LEB responders with moderate-to-severe AD who entered a long-term extension study, ADjoin. Methods: Itch was reported using the Pruritus Numeric Rating Scale (NRS), a patient-reported, single-item, daily, 11-point scale, where the minimal clinically important difference (MCID) is 3 points. Sleep loss due to itch was reported using the Sleep-Loss Scale, a patient-reported, single-item, 5-point scale, where the MCID is 1 point. We report =3-point improvement in Pruritus NRS among patients with baseline score at least 3, percent change from ADhere baseline (PCFB) in Pruritus NRS, Pruritus NRS (0,1), =1-point improvement in Sleep-Loss Scale score among patients with baseline score at least 1, =2-point improvement in Sleep-Loss Scale score among patients with baseline score at least 2 and PCFB in Sleep-Loss Scale score. All outcomes were reported at week 52 of ADjoin study, after a total of 68 weeks of LEB treatment. As observed analyses used all data collected. Results: At week 68, most patients reported maintaining ≥3-point improvement in Pruritus NRS treated with LEB Q2W (80.6%, 29/36) and LEB Q4W (88.9%, 16/18). Patients treated with LEB Q2W and LEB Q4W reported maintaining 65.3% and 59.4% improvement in Pruritus NRS at week 68 compared to ADhere baseline, respectively. At week 68, 45.9% (17/37) patients in LEB Q2W group and 31.6% (6/19) in LEB Q4W group reached Pruritus NRS of 0 or 1. At week 68, most patients reported maintaining ≥1-point improvement in Sleep-Loss Scale score treated with LEB Q2W (96.9%, 31/32) and LEB Q4W (85.7%, 12/14). Similarly, most patients reported maintaining ≥2-point improvement in Sleep-Loss Scale score treated with LEB Q2W (60.9%, 14/23) and LEB Q4W (75.0%, 6/8). Patients treated with LEB Q2W and Q4W reported maintaining 84.1% and 58.8% improvement in Sleep-Loss Scale score at week 68, respectively, compared to ADhere baseline. Conclusions: LEB + TCS maintained itch and sleep improvement at 68 weeks in patients with moderate-to-severe atopic dermatitis. [ABSTRACT FROM AUTHOR]

Introduction Lebrikizumab is a novel monoclonal antibody that binds with high affinity and slow off-rate to IL-13, thereby blocking the downstream effects of IL-13 with high potency. The efficacy and safety of lebrikizumab have been investigated in a number of Phase 3 trials including: ADvocate1 (NCT04146363), ADvocate2 (NCT04178967), ADhere (NCT04250337), and ADjoin (NCT04392154). Lebrikizumab (with or without TCS) was efficacious in providing clinically meaningful improvements in the signs and symptoms of AD through Week(W) 52 in adult and adolescent patients with moderate-to-severe AD. Objectives: We report the efficacy and safety of lebrikizumab (LEB) in the long-term extension study ADjoin (NCT04392154) following 104 weeks of continuous LEB treatment with and without TCS use. Methods: Patients in ADvocate1&2 who achieved either EASI 75 or IGA 0/1 (without rescue) at W16 were re-randomized 2:2:1 to LEB250mg Q2W, LEB250mg Q4W, or placebo (LEB withdrawal). Patients who completed W52 of ADvocate1&2 were able to enroll in ADjoin. Patients in ADhere who achieved either EASI 75 or IGA 0/1 (without rescue) at W16 were able to enroll into ADjoin and randomized 2:1 to LEB250mg Q2W or LEB250mg Q4W. Data are reported for patients originating from ADvocate1&2 and ADhere who received LEB250mg Q2W or Q4W in ADjoin. Efficacy outcomes were assessed based on all collected data (as observed analysis) up to 104W of LEB treatment. Safety was reported from ADjoin enrollment up to the data cut-off April 14, 2023. Results: At W104, IGA 0/1 was maintained by 38/44 (86.4%; Q2W) and 42/55 (76.4%; Q4W) patients from ADvocate1&2 and 26/31 (83.9%; Q2W) and 11/14 (78.6%; Q4W) patients from ADhere. EASI 75 was maintained by 65/68 (95.6%; Q2W) and 77/80 (96.3% Q4W) ADvocate1&2 patients and 39/41 (95.1%; Q2W) and 24/25 (96.0%; Q4W) ADhere patients at W104. In patients who achieved EASI 75 at W16, EASI 90 was achieved by 56/68 (82.4%; Q2W) and 66/80 (82.5%; Q4W) ADvocate1&2 patients and 35/41 (85.4%; Q2W) and 18/25 (72.0%; Q4W) ADhere patients at 104W.During ADjoin, 166/267 (62.2%) patients from the subpopulations of ADvocate1&2 and ADhere who received LEB Q2W or Q4W in ADjoin reported adverse events (AEs), most of which were mild (31.5%, n=84) or moderate (27.0%, n=72) in severity. Serious AEs were reported by 10 (3.8%) patients. There was one death in the ADhere Q2W arm. Six (2.3%) patients reported AEs leading to treatment discontinuation. The safety profile of LEB in ADjoin is consistent with that observed during ADvocate1&2 and ADhere. Conclusions: Efficacy outcomes were maintained long-term, over 2 years of continuous LEB treatment, in both LEB250mg Q2W and Q4W arms. The safety profile of LEB in ADjoin is consistent with previous LEB studies in patients with moderate-to-severe AD. [ABSTRACT FROM AUTHOR]

Background: Itch and sleep disturbance due to itch are burdensome symptoms associated with atopic dermatitis (AD). Rapid onset of action is important for AD treatments to improve quality of life and relieve suffering. Objectives: This subanalysis evaluated how quickly baricitinib 1-mg and 2-mg reduced itch and associated sleep disturbance during the first 7 days after treatment initiation in a phase 3, double-blind, placebo-controlled trial. Methods: Adult patients with AD were randomized 1:1:1 to placebo (N = 147), baricitinib 1 mg (N = 147) or baricitinib 2 mg (N = 146). Patients kept daily diaries, completing the Itch Numeric Rating Scale (NRS) (itch severity from 0 = no itch to 10 = worst itch imaginable) and the Atopic Dermatitis Sleep Scale (ADSS) to measure sleep disturbance (number of nighttime awakenings because of itch). Mixed model repeated measures analysis was used to analyze change from day 1 to day 7 values. Results: Patients receiving either dose of baricitinib had a 9.9% decrease in itch NRS scores from baseline to Day 2 vs 1.5% decrease for placebo (significant between-group least squares mean [LSM] difference: 8.3; 95% CI −12.66 to −3.89; P =.0002). Baricitinib 2 mg reduced nighttime awakenings due to itch (ADSS item 2) at day 2 by 25.2% vs 3.9% in the placebo group (between-group LSM difference: −21.4, P =.0025). Baricitinib 2 mg continued to demonstrate a statistically significant difference from placebo in sleep symptoms at day 7 (LSM difference −23.9; P =.001). Conclusions: Baricitinib 2-mg provided relief from itching and sleep disturbance in patients with AD, beginning the day after taking first dose.

Introduction: Real-world disease management of atopic dermatitis (AD) is hampered by a lack of consistency between providers that treat AD regarding assessment of severity, disease activity, and quality of life. Variability and inconsistency in documentation makes it difficult to understand the impact of AD. This study summarizes AD-related symptoms and concerns captured in unstructured qualitative provider notes by healthcare providers during visits with patients with AD. Methods: Provider notes were obtained for patients with AD (n = 133,025) from a USA-based ambulatory electronic health records system. The sample included both children (n = 69,551) and adults at least 18 years of age (n = 63,474) receiving treatment from a variety of specialties including primary care, dermatology, and allergy/immunology. Key skin-related words were identified from a review of a sample of notes and natural language processing (NLP) was applied to determine the frequency of the keywords and bigram patterns. Results: Provider notes largely focused on symptoms (primarily itch) and symptom relief rather than the impact of AD on work or lifestyle. Despite the known relationship between itch and skin pain, neuralgia was not widely documented. Compared to primary care providers, dermatologists' and allergist/immunologists' notes had more documentation of symptom-related issues. Personal and work/life burden issues were not widely documented regardless of specialty. Conclusion: The topics documented in case notes by healthcare providers about their patients with AD focus largely on symptoms and, to a lesser extent, treatment, but do not reflect the burden of AD on patients' lives. This finding highlights a potential care gap that warrants further investigation. [ABSTRACT FROM AUTHOR]

Introduction: Atopic dermatitis (AD) is associated with risk factors for venous thromboembolism (VTE). However, the risk of VTE among this population is unknown. The aim of this study was to assess the risk of VTE among adults with AD and compare the risk vs. matched non-AD controls. Methods: This retrospective study used claims data from the IBM Watson MarketScan® Commercial Claims and Encounters, Medicare Supplemental, and Medicaid databases to identify adults aged 18 years or older with AD. Incidence rates (IR) per 100 person-years (PY) of VTE were reported for three cohorts: overall AD, moderate-to-severe AD, and non-AD controls matched by age, sex, and calendar time to the overall cohort. Cox proportional hazards regression was used to estimate hazard ratios (HR) for VTE risk. Results: Overall, 198,685 patients with AD were identified. Crude VTE IRs were 0.24 for AD overall, 0.31 for moderate-to-severe AD, and 0.25 for non-AD controls. VTE risk was similar in patients with AD vs. non-AD controls (partially adjusted HR 1.00, 95% confidence interval [CI] 0.92, 1.09). VTE risk was greater in patients with moderate-to-severe AD vs. non-AD controls in partially adjusted models (HR 1.24, 95% CI 1.13, 1.36), but not after adjustment for healthcare use and VTE risk factors (HR 0.95, 95% CI 0.85, 1.07). Conclusions: AD was not an independent risk factor for VTE, and the risk of VTE among patients with AD was low. These findings provide valuable context for understanding VTE risk among patients with AD, which is particularly relevant as advanced therapies for the treatment of moderate to severe AD, such as janus kinase inhibitors, become available.

Introduction: Burdensome symptoms of atopic dermatitis include itch and sleep disturbance. This post hoc analysis reports the effect of baricitinib on itch and sleep disturbance during the first week of treatment in 3 phase 3 studies. Methods: Patients were randomized 2:1:1:1 to once-daily placebo or baricitinib 1 mg, 2 mg, or 4 mg in the BREEZE-AD1 and -AD2 studies and 1:1:1 to once-daily placebo or baricitinib 2 mg or 4 mg in the BREEZE-AD7 study. Topical corticosteroids were only allowed in BREEZE-AD7. Patients completed the itch numerical rating scale and atopic dermatitis sleep scale (ADSS) items 1–3 using an electronic daily diary. Data were analyzed by study as least squares mean percent change from baseline in daily scores for the randomized patients. Mixed model repeated measures analysis was used to analyze change from baseline values. Results: A total of 624, 615, and 329 patients were randomized in BREEZE-AD1, -AD2, and -AD7, respectively. Itch severity significantly improved with baricitinib 2 mg and 4 mg versus placebo starting at day 2 (1 day after first dose) in BREEZE-AD1 and -AD7 and at day 1 in BREEZE-AD2. Patients' ability to fall asleep (ADSS item 1) significantly improved with baricitinib 2 mg and 4 mg versus placebo starting at day 2 in all three studies. There were significant improvements in patients waking due to itch (ADSS item 2) with baricitinib 4 mg versus placebo starting at day 2 in all three studies. Patients' ability to return to sleep after being woken by itch (ADSS item 3) was significantly improved with baricitinib 4 mg versus placebo starting at day 2 in BREEZE-AD1 and -AD2 and at day 4 in BREEZE-AD7. Conclusion: Rapid onset of action, typically 1 day after taking the first dose of baricitinib, was observed consistently for the burdensome symptoms of itch and sleep disturbance.

Introduction: A number of treatments for atopic dermatitis (AD) are available; however, long-term treatment patterns and healthcare consumption in patients with AD are poorly described. Methods: We conducted a registry-based longitudinal drug utilization study among Danish patients with AD that were referred to their first-ever visit at hospital-based dermatology clinics. Their first visit was in the period between 1 January 2005 and 31 December 2012, and patients were followed up to 5 years after their first visit. Results: In total, 8213 people with a first-time hospital dermatologist contact for AD were included in the study (3514 aged 0–9 years, 1501 aged 10–19 years, 3198 aged 20 years or older). At first visit, a baseline history of moderately potent topical corticosteroid (TCS) use was seen among 46.6% of children (0–9 years), whereas potent or very potent TCS use was more frequently among older individuals (e.g., 51.1% and 25.6% of people aged 50 years or older had used potent and very potent TCS, respectively). The median (interquartile range) annual number of visits to general practitioners was 4 (2–7) for children and 5 (2–8) for adults, in the 12 months prior to referral. Three years after referral, these numbers had decreased to 2 (1–4) and 3 (1–6), respectively. In the first year after referral, 6% of patients were prescribed systemic corticosteroids, whereas other systemic therapies were used in 5% or less. Conclusions: After referral, low proportions of patients received systemic treatment, or potent TCS. These findings highlight considerable differences in treatment patterns between general practitioners and private practice dermatologists, compared with hospital-based dermatologists, and emphasize the need for better adherence to evidence-based treatment guidelines.

Introduction Lebrikizumab (LEB) is a monoclonal antibody (Ab) that has shown efficacy and safety in patients with moderate-tosevere atopic dermatitis (AD) in Phase 2/3 trials. LEB targets IL-13 and inhibits signaling of the IL-4Ra/IL-13Ra1 complex. The potential immunomodulator effect of LEB necessitates investigating its impact on immune responses. Objectives: To report the seroresponses to the Tdap (Diphtheria/Tetanus Toxoids/Pertussis) and MCV (Meningococcal (Groups A, C, Y, and W-135)) vaccines in LEB-treated and placebo (PBO)-treated adult patients (aged 18-15 years) with moderate-to-severe AD; and to compare the efficacy of LEB vs PBO in the treatment of AD. Methods: ADopt-VA was a US Phase 3, 16-week (W) randomized, double-blind, placebo-controlled study to assess LEB impact on vaccine immune responses in adult patients with moderate-to-severe AD. The primary endpoint was the immune response to 2 vaccines, the Tdap and MCV. LEB was given as a 500 mg loading dose at baseline and W2, followed by 250 mg LEB Q2W. At W12, both vaccines (Tdap and MCV) were administered to all patients, LEB group N=107, Placebo (PBO) group N=81. Immune responses were determined by Ab level differences between W12 and W16. Secondary efficacy endpoints at W16 were Investigator Global Assessment (IGA) and Eczema Area and Severity Index (EASI 75) scores. Results: For Tdap, 73.6% of LEB patients had a positive Ab response vs 73.4% for PBO, 90% CI, 0.3 (-10.2, 11.2). For MCV, LEB patients had an 86.9% positive Ab response vs 75.0% for PBO, 90% CI, 12.2 (2.5, 22.0). IGA (0,1) was achieved by 40.6% of LEB patients vs 18.9% receiving PBO (p=<0.001); EASI 75 was achieved by 58.0% and 32.7% (p<0.001), respectively. The safety profile was consistent with previous LEB trials. Conclusions: These data show that LEB does not negatively impact immune responses for Tdap or MCV vaccines in adults with moderate-to-severe AD. [ABSTRACT FROM AUTHOR]

The total treatment effect over placebo for changes in DLQI that could be accounted for by either itch or EASI was the indirect or mediation effect. With data from three monotherapy baricitinib phase III randomized clinical trials (RCTs), we conducted a posthoc mediator analysis to assess whether changes in itch or skin severity mediated the treatment effect over placebo on changes in health-related quality of life.

Little is currently known about possible associations between disease specific characteristics of atopic dermatitis (AD) and use of medical treatments. We explored the use of AD treatments within the past 12 months in Danish adults according to distinct patient characteristics. Patients who had received a diagnosis of AD in a hospital in‐ or outpatient setting as adults were surveyed and data cross‐linked to a national prescription registry. AD severity was measured by the Patient‐Oriented SCORing Atopic Dermatitis (PO‐SCORAD). A total of 3834 patients participated. Use of topical medication in the past 12 months increased with increasing AD severity, whereas no difference was observed for systemic medication use. Positive associations between AD in the face and neck, and use of mild and moderately potent topical corticosteroids were observed, while involvement of palms and chest was associated with use of more potent topical corticosteroids. The mean DLQI, skin pain, and itch severity scores were lower in patients managed only with topical corticosteroids (5.5, 3.2, and 4.3, respectively) compared to patients treated with both oral and topical medication (7.1, 3.8, and 5.0, respectively). Patients with frequent topical corticosteroid use tended to be older (50.7 vs 48.6 years), males (50.0% vs 33.6%), current daily smokers (17.3% vs 13.7%), and having asthma (59.1% vs 43.8%) compared with infrequent users of topical corticosteroids. We found a disconnect between the severity of AD signs and symptoms, and use of AD therapies. In particular, a very modest use of systemic immunosuppressants was seen even among patients with severe AD symptoms. However, the underlying clinical decisions and reasons behind this disconnect is not clear based on the current data. [ABSTRACT FROM AUTHOR]

Background: Pyoderma gangrenosum (PG) is an uncommon but severe extra-intestinal manifestation (EIM) of inflammatory bowel disease (IBD). The incidence and risk factors for PG are disputed. Aims: To assess the incidence of PG and identify factors associated with PG in IBD patients. Methods: A search of electronic databases (Ovid and PubMed) was conducted between 1966 and 2019. Studies that calculated the incidence of PG in IBD patient cohorts were included. Patient demographics, IBD subtype, and EIM presence were recorded. A review of our institutional database of 1057 IBD patients was conducted. A multivariate regression model and meta-analysis were conducted to identify risk factors for PG. A random effects model was used to combine the data of included studies. Results: Fourteen studies were included in addition to 1057 IBD patients and 26 PG cases from the Louisville cohort. In total, there were 379 cases of PG in the cumulative cohort of 61,695 IBD patients. The PG incidence in individual studies ranged from 0.4 to 2.6%. In the institutional cohort, ocular EIMs and a permanent stoma were significant risk factors for PG. In the meta-analysis, PG was associated with female gender (RR = 1.328, 95% CI 1.161–1.520), Crohn's disease (RR = 1.193, 95% CI 1.001–1.422), erythema nodosum (RR = 9.281, 95% CI 6.081–14.164), and ocular EIM (RR = 4.55, 95% CI 3.04–6.81). There was study heterogeneity when assessing IBD subtype, ocular, and joint EIMs. Conclusions: There are conflicting data on the incidence and risk factors for PG. This meta-analysis confirms an association between PG and female gender, Crohn's disease, erythema nodosum, and ocular EIM that have been described in smaller studies. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) can greatly impact quality of life in adolescents, and improved management is needed. Lebrikizumab, a high-affinity monoclonal antibody targeting interleukin (IL)-13, demonstrated clinical benefit in Phase 3 trials: ADvocate1, ADvocate2 and ADhere. This study aims to report 52-week safety and efficacy outcomes from ADore (NCT04250350), a Phase 3, open label study of lebrikizumab in adolescent patients with moderate-to-severe AD. Eligible adolescents (n = 206) (≥12 to <18 years; weighing ≥40 kg) received 500-mg loading doses at baseline and Week 2, and 250-mg lebrikizumab subcutaneous injections every 2-weeks (Q2W) for 52-weeks. Safety was monitored using adverse events (AEs), AEs leading to treatment discontinuation, vital signs and laboratory testing. Efficacy analyses included Investigator Global Assessment (IGA) and Eczema Area and Severity Index (EASI). A total of 172 patients completed the treatment period. Low frequencies of AEs leading to treatment discontinuation (2.4%) and SAEs (2.4%) were reported. Overall, 134 (65.0%) patients reported at least one treatment-emergent adverse event, most being mild or moderate in severity, including 14 (6.8%) conjunctivitis events. Efficacy was rapid, with 14.4% achieving IGA (0,1) at Week 4, increasing to 46.3% at Week 16 and 62.6% at Week 52. The EASI-75 was 28.6% at Week 4, 73.2% at Week 16, and 81.9% at Week 52. The mean percent improvement from baseline to Week 52 in EASI was 86.0%. Lebrikizumab open-label 250-mg Q2W had a safety profile in adolescents with moderate-to-severe AD, which was consistent with previous trials, with 2.4% treatment discontinuation due to AEs. Lebrikizumab demonstrated efficacy, with 81.9% of patients achieving EASI-75 and 62.6% achieving IGA (0,1) at Week 52. [ABSTRACT FROM AUTHOR]

Lebrikizumab (LEB) is a novel, high-affinity monoclonal anti - body that selectively binds to interleukin (IL)-13. To evaluate the efficacy and safety of LEB monotherapy in patients with moderate-to-severe atopic dermatitis (AD) in two identical phase 3 trials ADvocate1 (ADv1) and ADvocate2 (ADv2). Patients who responded to LEB 250 mg every 2 weeks (LEB Q2W) at the end of the 16-week induction period were re-randomized in a 2 : 2 :1 ratio to receive LEB Q2W, LEB 250 mg every 4 weeks (LEB Q4W) or placebo (LEB withdrawal) for an additional 36 weeks. Response, at week 16, was defined as achieving an IGA (0, 1) with a ≥2-point improvement or EASI75 and no use of rescue medication. Efficacy outcomes reported at week 52 included IGA (0, 1), EASI 75, ≥4-point reduction in Pruritis Numeric Rating Scale (NRS), EASI 90 and DLQI ≥4-point. Safety analysis was conducted on all patients who received ≥1 dose of LEB. Patients maintained IGA (0, 1) in LEB Q2W (ADv1, 75.8%; ADv2, 64.6%), LEB Q4W (ADv1, 74.2%; ADv2, 80.6%) and LEB withdrawal (ADv1, 46.5%; ADv2, 49.8%). Maintenance of EASI75 was, in LEB Q2W (ADv1, 79.2%; ADv2, 77.4%), LEB Q4W (ADv1, 79.2%; ADv2, 84.7%) and LEB withdrawal (ADv1, 61.3%; ADv2, 72.0%). For Pruritus NRS ≥4-point improvement from baseline, patients-maintained improvement in the LEB Q2W (ADv1, 81.2%; ADv2, 90.3%), LEB Q4W (ADv1, 80.4%; ADv2, 88.1%) and LEB withdrawal (ADv1, 65.4%; ADv2, 67.6%). Maintenance of EASI90 was, in LEB Q2W (ADv1, 66.1%; ADv2, 61.5%), LEB Q4W (ADv1, 66.6%; ADv2, 67.4%) and LEB withdrawal (ADv1, 45.5%; ADv2, 36.9%). DLQI ≥4-point improvement from baseline was LEB Q2W (ADv1, 64.0%; ADv2, 59.0%), LEB Q4W (ADv1, 62.7%; ADv2, 73.0%) and LEB withdrawal (ADv1, 57.7%; ADv2, 45.5%). TEAEs were reported by 58.1% (ADv1) and 67.8% (ADv2) LEB-treated patients at week 52. Serious adverse events were reported by 3.3% of ADv1 patients and 2.7% of ADv2 patients. In ADv1 and ADv2, 2.3% and 3.9% of patients reported an adverse event leading to treatment discontinuation, respectively. Both LEB Q2W and LEB Q4W maintained improvement in all reported outcomes for the treatment of moderate-to-severe AD through 52 weeks. The safety profile was consistent with previously published data.

Lebrikizumab, a high-affinity monoclonal antibody targeting IL-13, previously demonstrated clinical efficacy in adults and adolescents with atopic dermatitis (AD) in phase 3 trials. Here we evaluate 16-week efficacy outcomes of lebrikizumab in adolescent patients with moderate-to-severe AD from 3 randomized, double-blind, placebo-controlled phase 3 trials: ADvocate1, ADvocate2 and ADhere. Eligible adolescents (≥12 to <18 years weighing ≥40 kg) were randomized 2 : 1 to subcutaneous lebrikizumab (loading doses of 500 mg at Baseline and Week 2 followed by 250 mg every 2 weeks) or placebo in ADvocate1&2 as monotherapy, and in combination with topical corticosteroids (TCS) in ADhere. Efficacy analyses at Week 16 included IGA (0,1) with ≥2-point improvement, EASI-75, and Pruritus NRS ≥4-point improvement. Adolescent data from ADvocate1 and ADvocate2 were pooled, and ADhere data were analysed separately. ADvocate2 and ADhere analyses were performed on a modified population, excluding 10 adolescent patients from a single site whose eligibility could not be confirmed. Combined adolescent 16-week results from ADvocate1 and ADvocate2 [lebrikizumab (n = 67) vs. placebo (n = 35)] were IGA (0,1) with ≥2-point improvement from baseline 46.6% vs. 14.3% (P < 0.01), EASI-75 62.0% vs. 17.3% (P < 0.001) and Pruritus NRS ≥4-point improvement from baseline 48.9% vs. 13.1% (P < 0.01), respectively. The corresponding proportions in ADhere (lebrikizumab + TCS, n = 32; placebo + TCS, n = 14) were IGA (0,1) 57.3% vs. 28.6% (P = 0.071), EASI-75 88.0% vs. 57.1%, (P < 0.05) and Pruritus NRS 45.8% vs. 13.8%, (P = 0.078), respectively. Lebrikizumab treatment with or without TCS demonstrated clinical efficacy in adolescents with moderate-to-severe AD. [ABSTRACT FROM AUTHOR]

Lebrikizumab demonstrated robust efficacy during the first 16 weeks of treatment in ADvocate1 and ADvocate2. This study aims to describe the 52-week results of lebrikizumab-treated patients who did not meet the protocol-defined criteria for response at 16 weeks of treatment. During the induction period, patients were randomized 2 : 1 to lebrikizumab 250 mg or placebo every 2 weeks (Q2W) for 16 weeks. Protocol-defined criteria for response were characterized as achieving a 75% Eczema Area and Severity Index (EASI75) or an Investigator's Global Assessment of 0 or 1 (IGA 0,1) with a ≥2-point improvement and without rescue medication use. At Week 16, patients from the lebrikizumab treatment arm, who did not reach the criteria for response, were assigned to the Escape arm (n = 215). These patients continued to receive lebrikizumab 250 mg Q2W for an additional 36 weeks. Endpoints and measurements included at week 52 were EASI75, EASI90, IGA (0,1) and pruritus. Pruritus was assessed using an 11-point Pruritus Numeric Rating Scale (NRS). Data are presented as observed results with no imputation for missing data. Pooled results for patients who did not respond to lebrikizumab and entered the escape arm show 36.1% achieved IGA (0,1) with 2-point improvement at Week 52. In the same population, 75.5% achieved EASI75, 44.2% achieved EASI90 and 66.4% reported 4-point improvement in Pruritus NRS. These results suggest that patients, who do not achieve protocol-defined response at 16 weeks of treatment, can be slow responders and derive benefit from continuing long-term therapy with lebrikizumab.
