Lilly's EBGLYSS (lebrikizumab-lbkz) delivered up to four years of durable disease control for patients with moderate-to-severe atopic dermatitis

In the ADlong Phase 3b study, nearly all EBGLYSS-treated patients achieved meaningful skin improvement (EASI-75) for up to four years

75% of patients achieved a high bar of near-complete skin clearance (EASI-90) and 78% experienced significant itch relief (Pruritus NRS ≤4), one of the most bothersome symptoms for patients

80% of patients achieved durable results without the need for topical corticosteroids

INDIANAPOLIS, March 27, 2026 /PRNewswire/ -- New long-term data show Eli Lilly and Company's (NYSE:LLY) EBGLYSS (lebrikizumab-lbkz) delivered durable skin clearance and relief from persistent itch for up to four years for patients with moderate-to-severe atopic dermatitis (eczema) in an open-label extension study offering once-monthly maintenance injection. Interim findings from the first year of the ADlong Phase 3b study will be presented at the American Academy of Dermatology (AAD) Annual Meeting, taking place March 27-31 in Denver.¹

"These data underscore our unwavering commitment to expanding what people with moderate-to-severe atopic dermatitis can achieve with treatment," said Adrienne Brown, executive vice president and president, Lilly Immunology. "For too long the focus has been around symptom management and many patients struggle to achieve consistent disease control despite cycling through topical treatments. EBGLYSS is helping transform this treatment paradigm—allowing people the opportunity to reimagine life without the frequent interruptions caused by flares or topicals applied 2-3 times per day."

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

In the ADlong study, the majority of patients achieved a high bar of near-complete skin clearance and significant itch relief with up to four years of continuous EBGLYSS treatment. Most patients (77%) were on EBGLYSS monotherapy, and 80% achieved results without topical corticosteroids. In addition, 80% achieved these outcomes with EBGLYSS monthly maintenance dosing during the study.

* Data are reported as observed

** EASI=Eczema Area and Severity Index; EASI-75=75% reduction in EASI from baseline

† EASI-90=90% reduction in EASI from baseline

‡ IGA 0,1=Investigator's Global Assessment 0 or 1 ("clear" or "almost clear")

§ Pruritus NRS=Numeric Rating Scale rating itch from 0-10 with 10 being worst imaginable itch within the past 24 hours 

The safety of EBGLYSS in the first year of the ADlong study was consistent with the known profile in patients with moderate-to-severe atopic dermatitis, regardless of dose frequency, and no new safety signals were observed. The majority of adverse events were mild or moderate and did not lead to discontinuation. Reported treatment-related adverse events in the study included conjunctivitis (6.9%) and injection-site reactions (0.6%).

The ADlong study is ongoing and will continue for an additional year of treatment. These results reinforce previously reported long-term results for EBGLYSS for patients with moderate-to-severe atopic dermatitis. In addition, a post-hoc analysis presented at Maui Derm Hawaii 2026 on EASI-75 stable responders showed less than one flare per patient per year with EBGLYSS monthly maintenance dosing used as monotherapy.⁷

"There is still an unmet need for people with moderate-to-severe atopic dermatitis who frequently experience unpredictable flares and are in need of treatment options that go beyond just symptomatic relief and address the underlying inflammation driving skin symptoms and persistent itch," said Emma Guttman-Yassky, M.D., Ph.D., The Waldman Professor and Health System Chair, Department of Dermatology at the Icahn School of Medicine at Mount Sinai in New York. "These four-year findings reinforce that EBGLYSS has the potential to deliver durable disease control, helping patients flare less with or without topicals."

Lilly continues to raise the standard of care in dermatology and boldly invest in the next wave of immunology innovation, which includes big bets on next-generation modalities, the targeted expansion of small molecules and advancing novel science that uncovers the potential of incretins. Lilly recently shared topline findings from the TOGETHER-PsA and TOGETHER-PsO trials investigating the concomitant use of ixekizumab and an incretin-based therapy to treat adults with psoriatic disease and obesity or overweight with at least one additional weight-related comorbid condition. Lilly's investigational therapies include DC-853, a novel oral IL-17 inhibitor being studied for psoriasis, and eltrekibart, a novel monoclonal antibody that targets neutrophil-driven inflammation and is being assessed in hidradenitis suppurativa.

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 atopic dermatitis, in Europe.

About ADlong

ADlong (NCT05916365) open-label extension study is evaluating the long-term safety and efficacy of EBGLYSS 250 mg dosed every four weeks (Q4W) in patients with moderate-to-severe atopic dermatitis for a total of 108 weeks. Adult and adolescent (ages 12–17, weighing ≥40 kg) patients from select countries in Europe who completed the 100-week ADjoin extension study, including patients who completed the ADore trial (52 weeks), the ADhere trial (16 weeks), and Week 16 responders who completed the ADvocate 1 and 2 trials (52 weeks), were eligible to enroll in ADlong. Patients (N=174) in this analysis receive open-label EBGLYSS 250 mg Q4W, regardless of their previous treatment in ADjoin (Q2W or Q4W dose). The approved maintenance dose of EBGLYSS is 250 mg once monthly, after taking EBGLYSS every two weeks for the four-month initial dosing phase (or later once achieving adequate clinical response).⁸ Intermittent use of topical rescue medications and short-term systemic treatments was allowed.¹ If response was below EASI-50, Q2W could be used and thereafter Q4W could be resumed.

About EBGLYSS  

EBGLYSS is a monoclonal antibody that selectively targets and neutralizes IL-13 with high binding affinity and a slow dissociation rate.^3,4,8 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. 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-13.⁸

The EBGLYSS Phase 3 program in atopic dermatitis consists of seven key global studies evaluating over 1,600 patients, including two monotherapy studies (ADvocate 1 and 2), a combination study with topical corticosteroids (ADhere), long-term extension (ADjoin), adolescent open-label (ADore) and pediatric (ADorable 1 and 2) studies. EBGLYSS is also being studied in allergic rhinitis and chronic rhinosinusitis with nasal polyps.

EBGLYSS was approved in the U.S., Japan and Canada in 2024 and in the European Union in 2023. EBGLYSS is a first-line biologic treatment with the option of monotherapy that offers once-monthly maintenance dosing for adults and children 12 years of age and older who weigh at least 88 pounds (40 kg) with moderate-to-severe atopic dermatitis that is not well controlled with topical prescription therapies.⁸ EBGLYSS 250 mg/2 mL injection is dosed as a single monthly maintenance injection following the initial phase of treatment. The recommended initial starting dose of EBGLYSS is 500 mg (two 250 mg injections) at Week 0 and Week 2, followed by 250 mg every two weeks until Week 16 or later when adequate clinical response is achieved; after this, maintenance dosing is a single monthly injection (250 mg every four weeks) which can be used with or without topical corticosteroids.⁸

Lilly is committed to serving patients living with moderate-to-severe atopic dermatitis and is working to enable broad first-line biologic access to EBGLYSS for patients not well controlled with topical prescription therapy through commercial insurance. Lilly has coverage with all three major national pharmacy benefit managers and 94% of commercially insured patients have coverage through national health plans. We have expanded Medicaid coverage and are pursuing similarly broad Medicare coverage as part of Lilly's health equity and affordability initiative. Through Lilly Support Services, Lilly offers a patient support program including co-pay assistance for eligible, commercially insured patients.
