INDIANAPOLIS, June 9, 2026 /PRNewswire/ --Eli Lilly and Company(NYSE: LLY) announced today that theU.S. Food and Drug Administration(FDA) approved a regimen of one maintenance dose every eight weeks of a single injection (250 mg/2 mL) of EBGLYSS (lebrikizumab-lbkz) for subcutaneous use in adults and children 12 years of age and older who weigh at least 88 pounds (40 kg) with moderate-to-severe atopic dermatitis. EBGLYSS is already approved for a once-monthly maintenance dose, with long-term data showing durable disease control. Now, EBGLYSS gives patients with moderate-to-severe atopic dermatitis the option to manage their condition with as few as six maintenance injections per year.1
"Today's approval builds on EBGLYSS' established long-term durability, with a new option for one maintenance dose every eight weeks. For people living with moderate-to-severe atopic dermatitis, that means a treatment they only need to take as few as six times a year—without prescription topicals from the start," saidAdrienne Brown, executive vice president and president of Lilly Immunology. "EBGLYSS now gives patients the opportunity to flare less and live their lives with fewer interruptions from atopic dermatitis."
The approval is based on longitudinal exposure-response modeling data and supported by every-eight-week clinical data from an extension to the Phase 3 ADjoin long-term trial, which evaluated EBGLYSS maintenance dosing every four weeks or every eight weeks over 32 weeks.2
"The option to extend EBGLYSS maintenance dosing to every eight weeks represents an important moment for patients living with moderate-to-severe atopic dermatitis," saidPeter Lio, M.D., author of the ADjoin study and clinical assistant professor of dermatology and pediatrics,Northwestern University. "This new dosing regimen without mandatory topicals gives patients a new option to manage their condition based on individual needs. It's about meeting patients where they are in their lives."
No new safety signals were noted in the EBGLYSS safety data in the 32-week ADjoin Q8W extension. No patients discontinued due to adverse events through 32 weeks. The most common (≥1%) adverse reactions reported with EBGLYSS are conjunctivitis, injection site reactions and herpes zoster.1
"Living with moderate-to-severe atopic dermatitis often means dealing with a cycle of symptoms and time-intensive treatment routines during and in-between flares," saidKristin Belleson, president and CEO of theNational Eczema Association. "Patients living with moderate-to-severe atopic dermatitis seek treatments that can offer durable disease control and fewer injections. This new option can ease the burden, allowing patients to spend less time thinking about managing their condition on a daily basis."
Lilly has exclusive rights for development and commercialization of EBGLYSS in theU.S. and the rest of the world outsideEurope. Almirall has licensed the rights to develop and commercialize EBGLYSS for the treatment of dermatology indications, including atopic dermatitis, inEurope.
About the Q8W ADjoin Extension
The Q8W ADjoin extension (NCT04392154) evaluated EBGLYSS administered once every eight weeks (Q8W) and once every four weeks (Q4W), assessing its long-term safety and efficacy over 32 weeks in patients with moderate-to-severe atopic dermatitis across select countries. Adult and adolescent patients (ages 12–17, weighing ≥40 kg) who completed the 100-week ADjoin long-term study, including participants from the Phase 3 ADvocate 1 and 2 trials (52 weeks), ADore trial (52 weeks) and the ADopt-VA (16 weeks) trial, were eligible to enroll. Patients in this analysis received open-label EBGLYSS 250 mg, Q8W or Q4W, regardless of their previous treatment in ADjoin (Q2W or Q4W dose) or response at extension baseline. The approved maintenance dose of EBGLYSS is 250 mg every four weeks or 250 mg every eight weeks, after taking EBGLYSS 250 mg every two weeks for 16 weeks or later when adequate clinical response is achieved.
About EBGLYSS
EBGLYSS is a monoclonal antibody that selectively targets and neutralizes IL-13 with high binding affinity and a slow dissociation rate.1,3,4 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 atopic dermatitis, driving the type-2 inflammatory loop in the skin, and EBGLYSS selectively targets IL-13.1
The EBGLYSS Phase 3 program in atopic dermatitis consists of seven key global studies evaluating more than 1,600 patients, including two monotherapy studies (ADvocate 1 and 2), a combination study with topical corticosteroids (ADhere), long-term extension (ADjoin) and adolescent open-label (ADore) studies. The program also includes a study assessing the impact of EBGLYSS on vaccine immune response in adults (ADopt-VA). EBGLYSS has been studied in patients with skin of color (ADmirable) and in dupilumab-experienced patients (ADapt).
EBGLYSS was approved in theU.S.,JapanandCanadain 2024 and in theEuropean Unionin 2023. EBGLYSS is a first-line biologic treatment, administered with or without topical corticosteroids, that offers every-four-week or every-eight-week 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.1 In theU.S., 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 250 mg every four weeks or every eight weeks.1
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. ThroughLilly Support Services™ for EBGLYSS®, Lilly offers a patient support program including co-pay assistance for eligible, commercially insured patients.
