What is Ebglyss?

Ebglyss (lebrikizumab) is a biologic treatment for moderate-to-severe atopic dermatitis to help relieve itch and clear skin. Ebglyss is used for atopic dermatitis (moderate to severe) that is not well-controlled using prescription topical medicines in patients 12 years and older. 

Ebglyss targets the cause of atopic eczema inflammation to help improve dry, itchy, and irritated skin. In atopic eczema, a protein called IL-13 (Interleukin 13) is involved in the inflammation that causes atopic dermatitis.  Ebglyss works by blocking IL-13, which reduces inflammation and improves atopic dermatitis symptoms. It is from a class of medicines called an interleukin-13 antagonist.

Ebglyss is given as an injection under the skin (subcutaneous injection) every two weeks until Week 16 or later and then as a single monthly injection for maintenance dosing. 

Ebglyss FDA approval

Ebglyss FDA approval was granted to Eli Lilly on September 13, 2024, for moderate-to-severe atopic dermatitis (eczema) after positive results in ADvocate 1 (NCT04146363)  and ADvocate 2 (NCT04178967) clinical trials.
