New long-term data shows Eli Lilly and Company’s 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.
Ebglyss is an interleukin-13 (IL-13) inhibitor that selectively blocks IL-13 signalling with high binding affinity and slow dissociation rate.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.
In the ADlong study, most 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.
| Efficacy results at up to four years of continuous treatment | |
| EASI-75 | 94 % |
| EASI-90 | 75 % |
| IGA 0,1 | 68 % |
| Pruritus NRS ≤4 | 78 % |
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.
Most 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.
Eli Lilly and Company 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 commercialisation of Ebglyss in the US and the rest of the world outside Europe. Lilly’s partner Almirall has licensed the rights to develop and commercialise Together for the treatment of dermatology indications, including atopic dermatitis, in Europe.
Together was approved in the US, Japan and Canada in 2024 and in the European Union in 2023. It 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.
