News Release

Monthly EGBLYSS maintenance dosing sustained clear or almost-clear skin for up to three years in the vast majority of ADvocate 1 and 2 responders

Nearly 87 percent of patients taking EBGLYSS did not require either high-potency topical corticosteroids or systemic treatments during the three-year study

The safety profile at three years was consistent with the previously published two-year results

INDIANAPOLIS, Sept. 25, 2024 /PRNewswire/ -- More than 80 percent of adults and adolescents with moderate-to-severe atopic dermatitis who responded to EBGLYSS™ treatment at Week 16 in the ADvocate 1 and 2 monotherapy trials and continued treatment for up to three years experienced sustained skin clearance with monthly maintenance dosing. Eli Lilly and Company (NYSE: LLY) announced these new long-term results from the ADjoin long-term extension study, which will be presented at the European Academy of Dermatology and Venereology (EADV) Congress from Sept. 25-28 in Amsterdam, Netherlands.¹ 

EBGLYSS is an interleukin-13 (IL-13) inhibitor that selectively blocks IL-13 signaling with high binding affinity.^2,3,4 The cytokine IL-13 is key in atopic dermatitis, driving the type-2 inflammatory cycle in the skin, leading to skin barrier dysfunction, itch, skin thickening and infection.^5,6 

"The chronic and persistent signs and symptoms of atopic dermatitis affect patients' daily lives, highlighting the need for a treatment that can provide sustained, long-term relief," said Eric Simpson, M.D., M.C.R., professor of dermatology and director of clinical research at Oregon Health & Science University School of Medicine in Portland, Oregon, and senior author and investigator of the ADjoin analysis. "These three-year results provide compelling evidence of durable efficacy and a consistent safety profile, offering further long-term evidence for health care providers seeking a new biologic treatment option for their patients."

Patients taking EBGLYSS who completed 52 weeks in ADvocate 1 or 2 could enroll in ADjoin for an additional 100 weeks of continued treatment (up to 152 weeks of continuous treatment). Patients in this analysis of the long-term extension trial received treatment either 250 mg every two weeks (Q2W) or once monthly (Q4W). The approved maintenance dose of EBGLYSS is 250 mg Q4W. These data presented are part of ADjoin, the long-term extension study of the EBGLYSS trials, and include participants who responded to EBGLYSS treatment at Week 16 from ADvocate 1 and ADvocate 2. ¹

• 84 percent of these patients taking EBGLYSS once monthly and 83 percent taking EBGLYSS every two weeks maintained clear or almost-clear skin (IGA 0,1) at three years.¹
• 87 percent of these patients taking EBGLYSS once monthly and 79 percent taking EBGLYSS every two weeks achieved or maintained at least 90 percent improvement in disease extent and severity (EASI-90) at three years.¹
• 83 percent of these patients taking EBGLYSS once monthly and 91 percent taking EBGLYSS every two weeks did not require either high-potency topical corticosteroids or systemic treatments.¹

The safety profile of these patients taking EBGLYSS in ADjoin was consistent with previous EBGLYSS studies, and no new safety signals were observed up to three years of treatment. The majority of adverse events were mild or moderate. Less than three percent of patients experienced adverse events leading to treatment discontinuation. The most common side effects of EBGLYSS were conjunctivitis, injection site reactions and shingles (herpes zoster).¹

"Without adequate treatment, atopic dermatitis can leave people struggling with uncontrolled symptoms," said Mark Genovese, M.D., senior vice president of Immunology Development at Lilly. "EBGLYSS selectively targets IL-13, one of the main drivers of inflammation in eczema. These three-year data demonstrate that EBGLYSS given once monthly provides durable symptom relief for patients who need it most."

Additional data from this clinical study is underway, with results to be presented at future congresses. 

EBGLYSS was approved in the U.S. by the Food and Drug Administration (FDA) earlier this month. EBGLYSS was also approved in the European Union in 2023, as well as in Japan in January 2024, with additional markets expected later this year.

"These latest clinical data for EBGLYSS show the potential of this innovative medicine to provide sustained improvement of moderate-to-severe atopic dermatitis, a chronic and often debilitating condition," said Volker Koscielny, M.D., Chief Medical Officer at Almirall. "The data can help inform clinical decision-making and are reassuring, as they show that the vast majority of patients who respond to the treatment will continue to respond over time."

Lilly has exclusive rights for development and commercialization of EBGLYSS in the U.S. and the rest of the world outside Europe. Lilly's partner Almirall has licensed the rights to develop and commercialize EBGLYSS for the treatment of dermatology indications, including eczema, in Europe.

About ADjoin
ADjoin (NCT04392154) evaluated the long-term safety and efficacy of EBGLYSS treatment in patients with moderate-to-severe atopic dermatitis for up to 100 weeks (up to 152 weeks of continuous treatment with the parent studies). Patients taking EBGLYSS who completed any of the parent studies (ADvocate 1 and 2, ADhere, ADore, ADopt-VA) were able to enroll in ADjoin. The ADhere parent study includes patients taking topical corticosteroids with EBGLYSS as a combination therapy. Patients could also enroll directly into ADjoin without participating in a parent study. Patients in this analysis of the long-term extension trial received either EBGLYSS 250 mg every two weeks or once monthly.¹

INDICATION AND SAFETY SUMMARY 
EBGLYSS™ (EHB-glihs) is an injectable medicine used to treat adults and children 12 years of age and older who weigh at least 88 pounds (40 kg) with moderate-to-severe eczema (atopic dermatitis) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies. EBGLYSS can be used with or without topical corticosteroids.

It is not known if EBGLYSS is safe and effective in children less than 12 years of age or in children 12 years to less than 18 years of age who weigh less than 88 pounds (40 kg).

About EBGLYSS 
EBGLYSS is a monoclonal antibody that selectively targets and neutralizes IL-13 with high binding affinity and a slow dissociation rate.^3,4,7 EBGLYSS binds to the IL-13 cytokine at an area that overlaps with the binding site of the IL-4Rα subunit of the IL-13Rα1/IL-4Rα heterodimer, preventing formation of this receptor complex and inhibiting IL-13 signaling.⁵ IL-13 is implicated as a primary cytokine tied to the pathophysiology of eczema, driving the type-2 inflammatory loop in the skin, and EBGLYSS selectively targets IL-13.⁷

The EBGLYSS Phase 3 program consists of five key global studies evaluating over 1,300 patients, including two monotherapy studies (ADvocate 1 and 2), a combination study with topical corticosteroids (ADhere), as well as long-term extension (ADjoin) and adolescent open label (ADore) studies. Further data results from ADmirable and ADapt are expected to be shared in 2024 and early 2025.
