FDA Approves lebrikizumab for treatment of atopic dermatitis

The US food and Drug Administration has approved lebrikizumab for treatment of atopic dermatitis in adults and children ages above 12 years of age.

Eczema inflammation under the skin can lead to symptoms seen and felt on the outside. EBGLYSS works by targeting eczema inflammation throughout the body that can lead to dry, itchy and irritated skin.

EBGLYSS 250 mg/2 mL injection can be used with or without topical corticosteroids and 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).

"Patients still struggle to control their moderate-to-severe atopic dermatitis with currently available therapies. Many experience poor long-term disease control, and severe itch can significantly impact their daily lives," said Jonathan Silverberg, M.D., Ph.D., M.P.H., professor of dermatology at George Washington University School of Medicine and Health Sciences in Washington, DC, and first author of the New England Journal of Medicine manuscript summarizing EBGLYSS clinical trials. "Today's FDA approval of EBGLYSS is a big win for patients, as we now have a new first-line biologic treatment option for moderate-to-severe disease when topical prescriptions aren't enough."

The approval was based on results from the ADvocate 1, ADvocate 2, and ADhere studies, which included over 1,000 adults and children (aged 12 and older) with moderate-to-severe eczema who were unable to control their symptoms with topical prescription medicines. The primary endpoint for these studies was evaluated at 16 weeks and measured clear or almost clear skin (IGA 0,1).

In an average of two studies (ADvocate 1 and 2), 38 percent of people who took EBGLYSS achieved clear or almost-clear skin at 16 weeks (versus 12 percent with placebo) and 10 percent saw these results as early as four weeks. Of the people who experienced clear or almost-clear skin at Week 16, 77 percent maintained those results at one year with once-monthly dosing. Forty-eight percent of responders who were switched from EBGLYSS to placebo at Week 16 maintained these results at one year.

Similarly, in both studies, many people experienced itch relief with EBGLYSS. On average, 43 percent of people who took EBGLYSS felt itch relief at 16 weeks (compared to 12 percent who took placebo) and five percent felt relief as early as two weeks. Of the people who felt itch relief at Week 16, 85 percent still felt that relief at one year of treatment with monthly maintenance dosing. Sixty-six percent of responders who were switched from EBGLYSS to placebo at Week 16 maintained these results at one year.

"Eczema can affect people of all skin tones, ethnicities, genders and ages. Nearly 16.5 million adults in the U.S. have eczema, with 6.6 million experiencing moderate-to-severe symptoms like itchiness, dry and scaly skin, discoloration and rashes, which can lead to more scratching that may cause skin to crack and bleed," said Kristin Belleson, President and CEO of the National Eczema Association. "The approval of EBGLYSS provides hope and promise for the eczema community and those still seeking lasting relief from disruptive symptoms."

The most common side effects of EBGLYSS include eye and eyelid inflammation, such as redness, swelling and itching; injection site reactions and shingles (herpes zoster). EBGLYSS cannot be used in people allergic to lebrikizumab-lbkz or to any of the ingredients in EBGLYSS. The maintenance period was generally consistent with the 16-week safety profile throughout multiple studies. 

"People living with eczema have symptoms that can appear at the most inopportune times, creating unpredictability and impacting their everyday lives," said Daniel Skovronsky, M.D., Ph.D., chief scientific officer and president of Lilly Research Laboratories, and president, Lilly Immunology. "Today's approval allows people the opportunity to reimagine life with eczema as EBGLYSS offers a targeted approach to reduce a main cause of eczema inflammation. EBGLYSS provides long-lasting symptom relief with a convenient once-monthly maintenance dose."

EBGLYSS will be available in the United States in the coming weeks. Lilly is committed to setting new expectations for patients living with eczema and is working with insurers, health systems and providers to enable patient access to EBGLYSS. Through Lilly Support Services™ for EBGLYSS™, Lilly will offer a patient support program including co-pay assistance for eligible, commercially insured patients.

EBGLYSS was approved for use by the European Commission in 2023, as well as in Japan in January 2024 with additional markets expected later this year.

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 S.A. has licensed the rights to develop and commercialize EBGLYSS for the treatment of dermatology indications, including eczema, in Europe.

About ADvocate 1 and ADvocate 2

ADvocate 1 and ADvocate 2 are 52-week randomized, double-blind, placebo-controlled, parallel-group, global, Phase 3 studies designed to evaluate EBGLYSS as monotherapy in adults and children (aged 12 to less than 18 years of age and weighing at least 40 kg) with moderate-to-severe eczema.

During the 16-week treatment induction period, patients received EBGLYSS 500-mg initially and at two weeks, followed by EBGLYSS 250-mg or placebo every two weeks. In the maintenance period, patients with moderate-to-severe eczema who achieved a clinical response after 16 weeks of EBGLYSS treatment were re-randomized to receive EBGLYSS every two weeks or four weeks or placebo for an additional 36 weeks. Patients who required rescue treatment during the induction period or who did not meet protocol-defined response criteria at 16 weeks received open-label EBGLYSS every two weeks for an additional 36 weeks.

The primary endpoint was measured by an Investigator Global Assessment (IGA) score of clear (0) or almost clear (1) skin with a reduction of at least two points from baseline at 16 weeks. Key secondary endpoints were measured by Eczema Area and Severity Index (EASI) and the Pruritus Numeric Rating Scale. EASI measures extent and severity of the disease.

About ADhere

ADhere is a 16-week randomized, double-blind, placebo-controlled, parallel-group, global, Phase 3 study to evaluate the efficacy and safety of EBGLYSS in combination with topical corticosteroids (TCS) initiated in 211 adults and children (aged 12 to less than 18 years of age and weighing at least 40 kg) with moderate-to-severe eczema. In the study, patients' baseline eczema symptoms were inadequately controlled by topical medications.
