Depth of response data was also presented in patients that took part in the Advocate 1 (NCT04146363) and Advocate 2 (NCT04178967) phase 3 studies that took place over 52 weeks. Deep responses were defined as total skin clearance (Investigator’s Global Assessment [IGA], Eczema Area and Severity Index [EASI] 100, and itch relief [NRS 0,1]). Deep responses were achieved in 20% and 31% of patients in ADvocate 1 and ADvocate 2, respectively, by week 16 and were maintained or increased through week 52.1
Long-term clinically meaningful responses were observed in patients that help achieve disease control. Eighty-four percent of patients in the ADvocate 1 and 2 studies that responded to lebrikizumab at week 16 achieved a “clinically meaningful response in at least [1] domain of the disease (mild signs, symptoms, or quality of life impact),” at the 52-week mark, according to Almirall. Over 57% demonstrated response across all 3 domains.1
A significantly higher proportion of participants treated with lebrikizumab achieved EASI of 7 or less (mild) and EASI of 1 or less (clear/almost clear) at week 16 compared to placebo, a post-hoc analysis of the ADvocate 1 and Advocate 2 trials revealed.1
Regardless of baseline severity, the analysis revealed over 50% of those treated with lebrikizumab 250 mg every other week on nontherapy for 16 weeks achieved an EASI score indicating mild AD. An EASI score indicating clear or almost clear was achieved in approximately 20% of participants.1
Eli Lilly and Company owns exclusive rights for the development and commercialization of lebrikizumab in the United States and the rest of the world, not including Europe, where Almirall has licensed the rights for development and commercialization.1
