Lebrikizumab significantly improved skin clearance and itch in people with moderate-to-severe atopic dermatitis.

-Lebrikizumab led to significant improvements with at least 75 percent skin clearance in more than half of people with moderate-to-severe atopic dermatitis (AD), as measured by EASI, in Eli Lilly and Company's ADvocate 1 and ADvocate 2 Phase III clinical trials. In the top-line results from these two studies of lebrikizumab as a monotherapy in AD, primary and all key secondary endpoints, including skin clearance and itch improvement, were met at Week 16.

Lebrikizumab is a novel monoclonal antibody (mAb) that binds soluble IL-13 with high affinity, has high bioavailability, a long half-life and blocks IL-13 signaling. The FDA has granted Fast Track designation to lebrikizumab for moderate-to-severe AD in adult and adolescent patients (aged 12 to less than 18 years of age and weighing at least 40 kg). Fast Track designation is granted for a medicine that is intended to treat a serious condition and data demonstrate the potential to address an unmet medical need.

ADvocate 1 and ADvocate 2 are ongoing 52-week randomized, double-blind, placebo-controlled, parallel-group, Phase III studies designed to evaluate lebrikizumab as monotherapy in adult and adolescent patients (aged 12 to less than 18 years of age and weighing at least 40 kg) with moderate-to-severe AD. The primary efficacy endpoints were assessed at 16 weeks in the two studies and were 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 Week 16 and at least a 75 percent or greater change from baseline in their Eczema Area and Severity Index (EASI) score at Week 16..

Lebrikizumab also achieved key secondary endpoints versus placebo in patients with AD, including early onset in skin clearance and itch relief, improvement in interference of itch on sleep and quality of life. Key secondary endpoints were measured by the IGA, EASI, the Pruritus Numeric Rating Scale, Sleep-Loss due to Pruritus and the Dermatology Life Quality Index..

In the initial 16-week placebo-controlled period of ADvocate 1 and ADvocate 2, the incidence of treatment-emergent adverse events (AEs) and serious AEs among patients treated with lebrikizumab was consistent with that of the previous Phase II lebrikizumab study in AD. The most common AEs included conjunctivitis, nasopharyngitis and headache for lebrikizumab-treated patients. Discontinuations due to AEs were similar in the lebrikizumab group (1.4%) compared to placebo (1.7%)..
