LEO Pharma Presents Late-breaking Tralokinumab Data at EADV 2024 for Moderate-to-Severe Atopic Dermatitis (AD) in the Difficult-to-Treat Head and Neck Region

• Real-world findings showed that subgroup of patients treated with Adtralza^® (tralokinumab) / Adbry^® (tralokinumab-ldrm) and with head and neck (H&N) atopic dermatitis (AD) at baseline reported presence of AD in that area in 52.1% of patients after nine months of treatment.¹
• As part of one of LEO Pharma’s most extensive scientific programs at EADV to date, the late-breaking presentation examined interim data from the real-world TRACE study of adult AD patients who have been prescribed Adtralza/Adbry for up to nine months.¹
• Additional posters presented interim results of the TRACE study on effectiveness of Adtralza/Adbry treatment through various physician and patient reported outcomes such as improvements in Eczema Area and Severity Index (EASI), Investigator Global Assessment (IGA), itch, sleep disturbance and quality of life.^2,3

NOT FOR UK USE – NOT INTENDED FOR UK MEDIA

LEO Pharma A/S, a global leader in medical dermatology, today presented nine-month interim data from the TRACE study, showing that Adtralza^® (tralokinumab) / Adbry ^® (tralokinumab-ldrm) reduced the severity of moderate-to-severe atopic dermatitis (AD) in the head and neck region of the body (H&N).

Results were shared through one of LEO Pharma’s five late-breaking oral presentations at the 33^rd European Academy of Dermatology and Venereology (EADV) Congress in Amsterdam.¹

TRACE is an international, prospective, single-cohort study of adult patients with AD who were prescribed Adtralza / Adbry. At the data cut-off for this interim analysis, the following number of patients were included in the full analysis set (FAS): baseline (n=824), three months (n=668), six months (n=331), and nine months (n=143). The late-breaker analysis included patients who had AD involvement on the face, scalp, and/or neck (head and neck area) at baseline (79.5%, 655/824).^1-3

In patients with H&N AD at baseline, the percentage of patients still reporting AD in the H&N area decreased to 67.2% (363/540) at three months and 52.1% (62/119) at nine months. Similar decreases were seen in dupilumab-naïve (50%, 42/84) and dupilumab-experienced (57.1%, 20/35) patients at nine months.¹

Among patients with baseline H&N AD, the percentage of patients with an Investigator's Global Assessment score of 0 (clear) or 1 (almost clear) (IGA 0/1) increased from 1.4% (9/650) at baseline to 33.6% (172/512) at three months, 48.4% (121/250) at six months, and 57.4% (58/101) at nine months of treatment with Adtralza.¹

“Atopic dermatitis often affects multiple regions of the body but can be exceptionally burdensome and difficult to treat in the head and neck,” said Kreesten Meldgaard Madsen, Chief Development Officer, LEO Pharma. “We are particularly encouraged to see treatment with Adtralza / Adbry leading to such positive real-world outcomes in a challenging region of the body, regardless of previous biologic treatment.”

"Presenting this data on Adtralza / Adbry at EADV underscores our commitment to advancing treatment options for atopic dermatitis,” said Alexander Egeberg, Head of Global Medical Affairs, LEO Pharma. “The positive outcomes observed in the TRACE study not only highlight the real-world results of Adtralza/Adbry but also reinforce LEO Pharma's dedication to addressing the diverse needs of patients. With five late-breakers at this conference, we are proud to showcase our extensive scientific program and the significant strides we are making in dermatology."

Alongside the late-breaking data, two poster presentations used interim TRACE data to show improvements in patient-reported symptoms of itch and physician-assessed Eczema Area and Severity Index (EASI). Patients reported that nine months of treatment with Adtralza / Adbry improved symptoms of itch, with the mean Peak Pruritus Numeric Rating Scale (PP-NRS, where 0 = “no itch” and 10 = “worst itch imaginable”) improving from 6.3 at baseline (n=484) to 3.3 at 9 months (n=65). A physician-assessed outcome measure showed the mean Eczema Area and Severity Index (EASI) improved from 20.1 at baseline (n=631) to 3.6 at 9 months (n=88).^2,3

Separately to data shared from the TRACE study, a poster was shared from the ECZTEND open-label extension trial in AD patients aged 65 and over. In this vulnerable population, reporting of adverse events (AEs) remained consistent with existing data after up to 4.5 years of treatment, while the long-term efficacy profile showed sustained improvements in AD consistent with the larger trial population.⁴

About TRACE

TRACE is a prospective, non-interventional, international, single-cohort study of adult patients with AD who were prescribed tralokinumab according to national approved labels. Patients were enrolled between November 2021 and July 2023 and followed for one year. At data cut-off (October 15th, 2023) for the interim analysis, the following number of patients were included in the full analysis set (FAS): baseline (n=824), 3 months (n=668), 6 months (n=331), and 9 months (n=143).^1-3

About the ECZTEND - Long-Term Extension (LTE) Trial

ECZTEND (Long-term Extension Trial in Subjects With Atopic Dermatitis Who Participated in Previous Tralokinumab Trials) is an ongoing Phase 3, long-term, five-year, open-label, single-arm extension trial to evaluate the safety and efficacy of Adtralza in patients with atopic dermatitis who participated in the previous Adtralza monotherapy trials (ECZTRA 1 and ECZTRA 2), the combination therapy Adtralza plus TCS trial (ECZTRA 3), the Drug-drug interaction (DDI) trial (ECZTRA 4), the vaccine trial (ECZTRA 5), the adolescent trial (ECZTRA 6), the oral cyclosporine A trial (ECZTRA 7), the combination therapy Adtralza plus TCS trial in Japanese subjects (ECZTRA 8), and the Adtralza monotherapy skin barrier function trial (TraSki). Patients were permitted to enter ECZTEND after completion of the parent trial regardless of their treatment response or whether they were treated with Adtralza or placebo.^5,6

About Atopic Dermatitis

Atopic dermatitis is a chronic, inflammatory skin disease characterized by intense itch and eczematous lesions.⁷ Atopic dermatitis is the result of skin barrier dysfunction and immune dysregulation, leading to chronic inflammation.⁸ Type 2 cytokines, including IL-13, play an important role in the key aspects of atopic dermatitis pathophysiology.^7,8 Excessive IL-22 production is also known to contribute to the pathogenesis of AD.⁹

About Adtralza^® (tralokinumab) / Adbry ^® (tralokinumab-ldrm)

Adtralza^® (tralokinumab), which is marketed under the tradename Adbry^® in the U.S., is a high-affinity fully human monoclonal antibody developed to bind to and inhibit the interleukin (IL)-13 cytokine, which plays a role in the immune and inflammatory processes underlying atopic dermatitis signs and symptoms.^7,8 Adtralza/Adbry specifically binds to the IL-13 cytokine, thereby inhibiting interaction with the IL-13 receptor α1 and α2 subunits (IL-13Rα1 and IL-13Rα2).¹⁰

Adtralza^® is approved for the treatment of moderate to severe AD in adult and adolescent patients 12 years and older in the European Union, Canada, Great Britain, the United Arab Emirates, and South Korea. Adtralza is approved for use in adults with moderate to severe AD in the U.S., Switzerland, Saudi Arabia, and Japan.
