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 BALLERUP, Denmark--(BUSINESS WIRE)-- 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 pro 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. INDICATION AND IMPORTANT SAFETY INFORMATION What is ADBRY?

BALLERUP, Denmark I September 26, 2024 I LEO Pharma A/S, a global leader in medical dermatology, today announced positive results from the Phase 2a Mechanism of Action (MoA) trial, which assessed the mechanistic impact of investigational temtokibart and dupilumab in patients with moderate-to-severe atopic dermatitis (AD). Results were shared as a Late Breaker oral presentation at the 2024 EADV Annual Meeting. 1 The Phase 2a MoA trial assessed the impact of inhibiting the IL-22RA1 or interleukin 4 receptor alpha (IL-4Rα) on a mechanistic level in patients with moderate-to-severe AD. 1 The results showed that temtokibart 450 mg once every 2 weeks dosing (Q2W, n=8) significantly improved skin hydration faster and to a greater extent than dupilumab 300 mg Q2W (n=4). 1 Temtokibart significantly improved natural moisturizing factors PCA and UCA by Week 1 from baseline (p<0.0001). 1 Subsequent improvement in barrier function markers including terminal differentiation markers and cell adhesion molecules were also shown with temtokibart treatment. 1 In line with its respective MoA, dupilumab showed a strong and consistent decrease in Type 2-associated inflammatory markers particularly in immune cells and fibroblasts. 1 Clinical improvements in EASI and itch NRS from baseline to Week 16 were comparable for temtokibart and dupilumab. 1 These data suggest that IL-22RA1 blockade does not directly affect skin immune cells but can rapidly help improve barrier abnormalities, identifying a potential new MoA for patients with moderate-to-severe AD. 1 “The results of this trial provide new insights into the pathophysiology of AD and give us a unique understanding of the mode of action of temtokibart,” said Dr Christine Bangert, MD, Head of the Allergology Task Force of the Austrian Society of Dermatology and Venereology, Head of the atopic eczema outpatient clinic of the Medical University of Vienna, and the Principal Investigator for the Phase 2a MoA trial. “These data suggest that the IL-22 pathway is central to atopic dermatitis pathogenesis, demonstrating that Type 2 inflammation is not the only relevant driver of the disease.” Temtokibart is an investigational monoclonal antibody, currently in Phase 2 development for the treatment of moderate-to-severe AD, which blocks the IL-22RA1 receptor subunit thereby inhibiting the effect of the interleukin-22 (IL-22) cytokine, and also partially inhibits IL-20 and IL-24 signaling. 2,3 A Phase 2b dose finding trial is currently ongoing to evaluate the efficacy and safety of different doses of temtokibart in adult patients with moderate-to-severe AD. 4 The Phase 2b trial has finalized recruitment, and results are expected in Q1 2025. LEO Pharma is also exploring indications outside dermatology for temtokibart in diseases where the IL-22 pathway is known to play a key role. “We are encouraged by the results of this AD trial exploring how targeting the disease from different angles with different mechanisms of action impacts disease markers,” said Kreesten Meldgaard Madsen, Chief Development Officer, LEO Pharma. “ These results further clarify the mode of action of temtokibart, giving reasons to believe temtokibart could also address unmet needs in other diseases where the IL-22 pathway is known to play a key role. LEO Pharma is currently exploring temtokibart for inflammation induced anemia.” LEO Pharma and argenx, a global immunology company, formed a strategic alliance in 2015 to develop innovative antibody-based solutions for the treatment of chronic inflammation that underlies many skin conditions. LEO Pharma and argenx jointly developed temtokibart under an exclusive option and research agreement. LEO Pharma obtained the license to temtokibart in 2022 and now assumes the responsibility to develop and commercialize temtokibart. About the Phase 2a MoA trial The temtokibart Phase 2a MoA trial (NCT05470114) was a randomized, double-blind, active comparator-controlled, 16-week, single-site, exploratory, mechanistic trial to assess the effect of temtokibart on the molecular signature and safety in adults with moderate-to-severe AD. 1,5 Patients were randomized 2:1 to receive either temtokibart 450 mg Q2W (n=8) or dupilumab 300 mg Q2W (n=4), for 16 weeks. 1 The primary endpoint was change in gene expression typically associated with AD in lesional skin biopsies from baseline to Week 4. 5 The key secondary endpoint was number of treatment-emergent adverse events from baseline to Week 16 per subject. 5 About the Phase 2b trial The temtokibart Phase 2b trial (NCT05923099) is an ongoing randomized, double-blind, placebo-controlled, multi-site, parallel-group, dose finding trial to evaluate the efficacy and safety of different doses of subcutaneously administered temtokibart in adult patients with moderate-to-severe AD. 4 Patients were randomized to receive one of four doses of temtokibart or placebo. 4 The primary endpoint is percent change in EASI score from baseline to Week 16. 4 The key secondary endpoint is number of treatment-emergent adverse events from baseline to Week 16 per subject. 4 About atopic dermatitis AD is a chronic, inflammatory skin disease characterized by intense itch and eczematous lesions. 6 AD is the result of skin barrier dysfunction and immune dysregulation, leading to chronic inflammation. 7 Type 2 cytokines, including IL-13, play an important role in the key aspects of atopic dermatitis pathophysiology. 8,9 Excessive IL-22 production is also known to contribute to the pathogenesis of AD. 10,11 About investigational temtokibart Temtokibart is an investigational monoclonal antibody that targets the IL-22RA1 receptor subunit, currently in Phase 2 development for the potential treatment of moderate-to-severe AD. 2,3 It blocks the IL-22RA1 subunit and thereby inhibits the effects of the IL-22 cytokine, and also the effects of IL-20 and IL-24 signaling. 2,3 Temtokibart does not bind to the IL-22 cytokine itself. 2,3 LEO Pharma has obtained a worldwide exclusive license to develop and commercialize temtokibart from argenx.

About Chronic Hand Eczema Chronic hand eczema (CHE) is defined as hand eczema (HE) that lasts for more than three months or relapses twice or more within a year. 29,30 CHE is one the most common skin disorder of the hands with a prevalence rate of approximately 4.7%. 31 In a substantial number of patients, HE can develop into a chronic condition. 32 CHE is a fluctuating disorder characterized by itch and pain, and patients may experience signs such as erythema, scaling, lichenification, hyperkeratosis, vesicles, edema, and fissures on hands and wrists. 33 CHE has been shown to cause psychological and functional burdens that impact patient quality of life, 34 with approximately 70% of individuals who live with severe CHE admitting to problems in performing everyday activities, and suffering disruption in their daily life due to the condition. 35 Furthermore, careers and earning potential have also been shown to be impacted by the burden of living with CHE. 36 About Atopic Dermatitis Atopic dermatitis is a chronic, inflammatory skin disease characterized by intense itch and eczematous lesions. 37 Atopic dermatitis is the result of skin barrier dysfunction and immune dysregulation, leading to chronic inflammation. 38 Type 2 cytokines, including IL-13, play an important role in the key aspects of atopic dermatitis pathophysiology. 37,38 Excessive IL-22 production is also known to contribute to the pathogenesis of AD. 39 About Psoriasis Psoriasis is a chronic, systemic inflammatory disease that primarily affects the skin in 125 million people worldwide. 40,41 Psoriasis is the result of skin barrier cell proliferation and the activation of cytokines (a family of proteins involved in immune responses) that cause inflammation. 42 About 80% to 90% of patients are affected by plaque psoriasis, the most common clinical form of psoriasis. 43 The symptoms of plaque psoriasis are itchy or painful raised scaly and inflamed plaques. Plaques may appear anywhere on the body, but often appear on the scalp, knees, elbows and torso. 43 About Anzupgo ® (delgocitinib) cream Anzupgo ® (delgocitinib) cream 20 mg/g is a topical pan-Janus kinase (JAK) inhibitor for the treatment of moderate to severe CHE. It inhibits the activation of JAK-STAT signaling, which plays a key role in the pathogenesis of CHE. 44 The pathophysiology is characterized by skin barrier dysfunction, inflammation of the skin, and alterations of the skin microbiome. 45 Anzupgo is currently approved in the European Union for the treatment of moderate to severe chronic hand eczema (CHE) in adults for whom topical corticosteroids are inadequate or inappropriate. In 2014, LEO Pharma A/S and Japan Tobacco Inc. (JT) entered into a license agreement in which LEO Pharma gained exclusive rights to develop and commercialize delgocitinib cream for topical use in dermatological indications worldwide, excluding Japan, where JT retains rights. 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. 38,46 Adtralza ® specifically binds to the IL-13 cytokine, thereby inhibiting interaction with the IL-13 receptor α1 and α2 subunits (IL-13Rα1 and IL-13Rα2). 47 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. About Kyntheum ® (brodalumab) Kyntheum ® (brodalumab) is a recombinant fully human monoclonal immunoglobulin IgG2 antibody that binds with high affinity to human IL-17RA and blocks the biological activities of the pro-inflammatory cytokines IL-17A, IL-17F, IL-17A/F heterodimer, IL-17C and IL-17E (also known as IL-25), resulting in inhibition of the inflammation and clinical symptoms associated with psoriasis. IL-17RA is a protein expressed on the cell surface and is a required component of receptor complexes utilized by multiple IL-17 family cytokines. IL-17 family cytokine levels have been reported to be increased in psoriasis. IL-17A, IL-17F and IL-17A/F heterodimer have pleiotropic activities including the induction of pro-inflammatory mediators such as IL-6, GROα, and G-CSF from epithelial cells, endothelial cells and fibroblasts that promote tissue inflammation. IL-17C has been shown to induce similar responses as IL-17A and IL-17F in keratinocytes. Blocking IL-17RA inhibits IL-17 cytokine-induced responses resulting in normalization of inflammation in the skin. 48 Kyntheum ® is indicated in the European Union, Great Britain, the United Arab Emirates, and Brazil for the treatment of moderate to severe plaque psoriasis in adult patients who are candidates for systemic therapy. About temtokibart Temtokibart (LEO 138559) is an investigational monoclonal antibody that targets the IL-22RA1 receptor subunit, currently in Phase 2 development for the potential treatment of moderate to severe atopic dermatitis. 49 It blocks the IL-22RA1 subunit and thereby inhibits the effects of the IL-22 cytokine, and potentially also to some extent the effects of IL-20 and IL-24. 49 Temtokibart does not bind to the IL-22 cytokine itself. 49 LEO Pharma has obtained a worldwide exclusive license to develop and commercialize temtokibart from argenx.
