Abstract Introduction/Background Tralokinumab is a high-affinity monoclonal antibody that specifically targets IL-13, a driver of inflammation in atopic dermatitis (AD). The ECZTRA 1, 2, 3, and 6 trials demonstrated that tralokinumab is efficacious and safe in adults and adolescents; however, real-world evidence on tralokinumab use is limited. Objectives To assess the change from baseline in clinician-assessed and patient-reported outcomes (PROs) among US adults with AD following 6 months of persistent tralokinumab use after treatment initiation in the CorEvitas AD registry. Methods The CorEvitas AD Registry is a prospective, non-interventional registry launched in July 2020 for adult AD patients under the care of a licensed dermatologist or qualified dermatology practitioner. This analysis includes US patients enrolled in the CorEvitas AD registry who initiated tralokinumab between February 1, 2022 and May 31, 2023, had baseline data, and were persistent on tralokinumab at the 6-month follow-up (defined as a visit occurring 5 to 9 months from tralokinumab initiation). Baseline data were summarized using descriptive statistics and stratified by advanced systemic therapy (AST) experience (defined as any previous history of dupilumab, abrocitinib, or upadacitinib). Outcome measures collected included: validated Investigator’s Global Assessment for atopic dermatitis (vIGA-ADTM), ≥50%/≥75% improvement in Eczema Area and Severity Index (EASI) (EASI-50/75), ≥4-point improvement in Dermatology Life Quality Index (DLQI), ≥3-point improvement in mean weekly pruritis numerical rating scale, and mean change in Work Productivity and Activity Impairment (WPAI). Results Among the 60 patients in this analysis, the mean age was 49.1 years and mean AD duration was 15.0 years. The majority of patients were female (34/60, 56.7%), White (51/60, 85.0%), worked full-time (38/60, 63.3%), and AST-naïve (44/60, 73.3%). At baseline, the majority of patients had moderate-to-severe AD based on EASI (EASI≥ 7, 40/60, 67%) and vIGA-ADTM (vIGA-ADTM 3: 50/60, 83.3%; vIGA-ADTM 4: 4/60, 6.7%). Disease severity was lower in AST-experienced patients, all of whom were dupilumab-experienced. A notable proportion of patients experienced improvements in clinician-assessed endpoints and PROs from baseline to 6 months: vIGA-ADTM ≤1 from 6.7% (4/60) to 55.0% (33/60), EASI ≤7 from 33.3% (20/60) to 85.0% (51/60), and DLQI ≤5 from 38.3% (23/60) to 66.7% (40/60). Among patients with EASI ≥7.1 at baseline, 85.0% (34/40) achieved EASI-50 (AST-naïve: 90.9%, 30/33; AST-experienced: 57.1%, 4/7) and 77.5% (31/40) achieved EASI-75 (AST-naïve: 84.8%, 28/33; AST-experienced: 42.9%, 3/7) at the 6-month follow-up. In patients with vIGA-ADTM of 3 or 4 at baseline, 79.6% (43/54) achieved EASI-50 (AST-naïve: 83.3%, 35/42; AST-experienced: 66.7%, 8/12) and 66.7% (36/54) achieved EASI-75 (AST-naïve: 76.2%, 32/42; AST-experienced: 33.3%, 4/12) at follow-up. Among patients with baseline DLQI ≥4, 71.4% (30/42) achieved ≥4-point improvement at follow-up (AST-naïve: 78.1%, 25/32; AST-experienced: 50.0%, 5/10). Of patients with baseline mean weekly pruritus NRS ≥3, 69.8% (37/53) achieved ≥3-point improvement at follow-up (AST-naïve: 70.0%, 28/40; AST-experienced: 69.2%, 9/13). Among the 40 patients employed at both baseline and follow-up visit, improvements were reported in WPAI. Percent impairment at work due to AD decreased by 14.8% (95% CI: -25.6%; -3.9%) and percent overall work impairment due to AD decreased by 15.7% (95% CI: -26.4%; -5.0%). For all 60 patients, non-work activity impairment due to AD decreased by 14.5% (95% CI: -23.9%; -5.1%). Conclusions In this real-world study, patients with AD experienced notable improvements in both clinician-assessed and patient-reported outcomes after 6-months of persistent tralokinumab treatment, regardless of prior AST therapy use. All 16 AST-experienced patients had prior use of dupilumab. These findings support the therapeutic potential of tralokinumab for AD patients, highlighting the need for future studies with longer follow-up period and larger sample size.

Purpose: Evidence on treatment preferences of patients with moderate-to-severe atopic dermatitis (AD) in the United States (US) is limited and an assessment of treatment preferences in this group is warranted.Materials and methods: An online discrete choice experiment survey was conducted (June 2023) among US adults with self-reported moderate-to-severe AD or experience with systemic therapy who had inadequate response to topical treatments. Preference weights estimated from conditional logistic regression models were used to calculate willingness to trade off and attributes’ relative importance (RI).Results: Participants (N = 300; mean age: 45 years; 70% females; 52% systemic therapy experienced) preferred treatments with higher efficacy, lower risk of adverse events (AEs), and less frequent blood tests (p < .05). Treatment attributes, from high to low RI, were itch control (38%), risk of cancer (23%), risk of respiratory infections (18%), risk of heart problems (11%), sustained improvement in skin appearance (5%), blood test frequency (3%), and frequency and mode of administration (2%); together, AE attributes accounted for more than half of the RI.Conclusions: Participants preferred AD treatments that maximize itch control while minimizing AE risks, whereas mode of administration had little impact on preferences. Understanding patients’ preferences may help improve shared decision-making, potentially leading to enhanced patient satisfaction with treatment, increased engagement, and better clinical outcomes.

Abstract Introduction/Background Atopic dermatitis (AD) is a common chronic condition affecting 5-10% of adults worldwide. AD symptoms (e.g., itching) can lead to sleep disturbances and affect daily activity and work productivity. Objectives With the evolving treatment landscape for moderate-to-severe AD, including advanced systemic therapies like biologics and Janus-kinase (JAK) inhibitors, a contemporary appraisal of the clinical burden and impairment in patients with moderate-to-severe AD in the United States (US) is warranted. Methods A web-based survey was conducted in June 2023 among US adults (≥ 18 years) with self-reported moderate-to-­severe AD or who had experience with systemic therapy, were diagnosed with AD for ≥ 1 year, and with inadequate response to topical treatments. Demographic and clinical characteristics (e.g., comorbidities, body regions ever affected by AD) at the time of the survey were summarized descriptively, along with productivity/activity burden (i.e., activity impairment, work impairment, absenteeism, presenteeism) using the Workers Productivity and Impairment Activity Index (WPAI). Analyses were reported overall and separately for White, Black, and Asian participants. Results 300 participants from all US regions completed the survey (White: 234 [78.0%], Black: 37 [12.3%], Asian: 16 [5.3%], Other/Unknown: 13 [4.4%]). Overall, participants’ mean age was 45 years, 70% were female, and 66% were employed. Half had experienced severe symptoms at any time (50%), and 52% had experience with systemic therapy. At the time of the survey, over 90% of participants were receiving treatment for AD, and 20% self-reported current symptoms as mild (moderate: 69%, severe: 11%). Approximately half reported AD affected their face (46%), neck (52%), or feet (54%) at any time. The most frequently reported comorbidities were anxiety (53%), depression (39%), high blood pressure (25%), allergic rhinitis (24%), and asthma (22%). Most participants (85%) reported some activity impairment due to AD with a mean activity impairment score of 37.6%. A majority (82%) of employed participants reported some work impairment due to AD with a mean overall work impairment score of 38.5%, absenteeism of 7.1% and presenteeism of 36.0%. Race-stratified analysis indicated that Black patients were diagnosed at a younger age, with a numerically higher proportion reporting severe disease (70%) and more affected by AD on the face (54%), neck (68%), and feet (62%) at any time compared to White and Asian patients. All race groups reported substantial activity impairment (33.0%-38.6%) and work impairment (27.2%-39.9%). Conclusions Moderate-to-severe AD is associated with a high disease burden with severity of symptoms across the US population, leading to substantial activity and productivity impairments. Given half of the patients in this study had never received systemic therapy, wider use of available treatment options may improve disease and symptom management, thereby reducing activity and work impairment.

Introduction: Tralokinumab, a high-affinity, monoclonal antibody that targets IL-13, is approved in the EU and Canada for adolescents (aged ≥12 years) with inadequately controlled moderate-to-severe atopic dermatitis (AD), and it does not require laboratory monitoring. The phase 3 ECZTRA 6 (NCT03526861) clinical trial demonstrated efficacy and safety up to 52 weeks in that population.&#x0D; Objective/Purpose: To further characterize the safety profile of tralokinumab by evaluating laboratory parameters of adolescents in the ECZTRA 6 trial.&#x0D; Methods: ECZTRA 6 subjects received tralokinumab 150mg (n=98), 300mg (n=97) or placebo (n=94) every 2 weeks (Q2W) from week 0–16 after a loading dose at week 0 (twice the subsequent dose), and then randomized to maintenance [original tralokinumab dose either Q2W or every 4 weeks (Q4W) or placebo Q2W] or open-label (tralokinumab 300mg Q2W) until week 52. Laboratory parameters included hematology, serum biochemistry, and urinalysis throughout the trial (weeks 0, 8, 16, 28, and 52).&#x0D; Results: Overall (n= 289 subjects), laboratory baseline parameters were similar across treatment groups. Mean and median changes of most hematology parameters showed minor fluctuations within the normal ranges through week 52, except for eosinophils. At baseline, elevated mean eosinophil counts (&gt;0.5 109/L) were observed for 40.8% (tralokinumab 150mg), 48.5% (tralokinumab 300mg), and 43.6% (placebo) of subjects in each respective treatment group. Some tralokinumab-treated patients had small transient increases in eosinophils (maximum mean change from baseline 0.2×109/L) before week 16. Continued treatment with tralokinumab or placebo did not correspond with further increase in eosinophil levels over time, and no adverse events of eosinophilia were reported. Mean levels of most biochemistry parameters, including electrolytes, renal and liver function parameters, and lipid panel, were within normal range at baseline, and mean and median changes showed minor fluctuations within normal ranges in all treatment arms. Mean lactate dehydrogenase levels were around or above the upper limit of normal at baseline and decreased to within the normal ranges during the trial across all groups. Overall, no clinically meaningful differences were observed in hematology, biochemistry, or urinalysis parameters between active treatment groups or placebo.&#x0D; Conclusions: Similar to findings in adult trials, no meaningful changes in laboratory parameters were observed in adolescents through week 52 with tralokinumab treatment. No routine laboratory monitoring is needed for adult or adolescent AD patients treated with tralokinumab.

Investigator's Global Assessment of clear/almost clear skin (IGA 0/1) is a difficult endpoint to achieve after short-term treatment of chronic moderate-to-severe atopic dermatitis, and does not fully reflect clinically meaningful changes in other parameters. We assessed the impact of tralokinumab versus placebo on other clinically meaningful parameters in patients not achieving IGA 0/1 at week 16 using pooled data from two monotherapy phase III trials, ECZTRA 1 and 2. This post hoc analysis included patients (n = 1328) from ECZTRA 1 and 2 who did not achieve the co-primary endpoint, IGA 0/1 at week 16 without rescue medication. Endpoints evaluating atopic dermatitis extent and severity included proportions of patients achieving IGA 0/1, 50%, 75%, and 90% improvement in Eczema Area and Severity Index (EASI-50/75/90); endpoints evaluating patient-reported outcomes included a ≥3-point improvement in worst daily pruritus Numerical Rating Scale (NRS), a ≥3-point improvement in eczema-related sleep interference (sleep) NRS, a ≥4-point improvement in Dermatology Life Quality Index (DLQI), and DLQI ≤5. Specifically, clinically meaningful responses were defined as EASI-50, a ≥3-point improvement in itch NRS, or a ≥ 4-point improvement in DLQI at week 16. Among ECZTRA 1 and 2 patients who did not achieve IGA 0/1 at week 16 without rescue medication, a significantly greater proportion of patients receiving tralokinumab versus placebo achieved EASI-50 (33.0% vs 13.0%), a ≥ 3-point improvement in itch NRS (22.6% vs 9.4%), or a ≥4-point improvement in DLQI (41.2% vs 24.5%) at week 16. In addition, compared with placebo, a numerically greater proportion of tralokinumab-treated patients achieved all three measures of clinically meaningful response (30% vs 18%) or a clinically meaningful change in at least one outcome (48.8% vs 28.5%). Significantly greater proportions of patients receiving tralokinumab versus placebo achieved additional clinician-reported and patient-reported outcomes, such as EASI-75 (13.5% vs 4.1%), EASI-90 (3.5% vs 1.1%), DLQI ≤5 (22.5% vs 12.5%), and a ≥3-point improvement in sleep NRS (24.5% vs 11.5%). Tralokinumab provided clinically meaningful responses in patients with moderate-to-severe atopic dermatitis who did not achieve IGA 0/1 at week 16 and/or used rescue medication. Using multiple validated outcome measures of both efficacy and quality of life, alongside IGA scores, can better characterize tralokinumab treatment responses in patients with moderate-to-severe atopic dermatitis.

Abstract In the monotherapy phase 3 trial (ECZTRA 6, NCT03526861) in adolescents with moderate-to-severe atopic dermatitis (AD) treated with tralokinumab, IGA of clear/almost clear skin (IGA 0/1) at week 16 was a primary endpoint. IGA 0/1 can be a high standard to achieve for patients with moderate-to-severe AD and may not fully reflect achievement of other clinically meaningful parameters, such as improvement in signs, symptoms and/or quality-of-life (QoL). To assess the impact of tralokinumab (150 or 300 mg) vs. placebo on other clinically meaningful parameters at week 16 in the subset of patients who did not achieve IGA 0/1 at week 16 and/or used rescue medication. Adolescents (12–17 years) were randomized to subcutaneous tralokinumab 150 or 300 mg, or placebo, every 2 weeks. Patients who did not achieve IGA 0/1 at week 16 and/or utilized rescue therapy were included in this post-hoc analysis. Non-responder imputation was used for patients who utilized rescue therapy or had missing data. Clinically meaningful responses were defined as EASI-50, ≥ 3-point improvement in pruritus NRS, or ≥6-point improvement in CDLQI. At week 16, 78.6% and 82.5% of tralokinumab-treated patients (150 mg/300 mg) vs. 95.7% (placebo) exhibited IGA &amp;gt; 1 and/or used rescue therapy. 36.4% (150 mg) and 52.5% (300 mg) of patients with IGA &amp;gt; 1 in the tralokinumab arms, compared to 21.1% (placebo), achieved clinically meaningful responses in at least one measure: EASI-50, pruritus NRS, or CDLQI. Greater proportions of tralokinumab-treated patients (150/300 mg vs. placebo) achieved EASI-50 (31.2%/41.3% vs. 10.0%) and ≥3-point improvement in pruritus NRS (21.6%/22.8% vs. 8.0%). A greater proportion of tralokinumab 300 mg patients vs. placebo (35.2% vs. 15.0%) achieved ≥6-point improvement in CDLQI. Many tralokinumab-treated adolescents who did not achieve IGA 0/1 at week 16 and/or used rescue therapy still achieved clinically meaningful improvements in AD signs, symptoms, and/or QoL.
