Abstract
Introduction: Atopic dermatitis is a complex, chronic, inflammatory skin disease that requires long-term control of symptoms like itch and sleep loss and improvement in quality of life, in addition to reduction of clinical signs. Lebrikizumab is a selective interleukin-13 inhibitor approved in the European Union, United Kingdom, United Arab Emirates, Canada, and Japan for treatment of moderate-to-severe atopic dermatitis in adults and adolescents. Here, we assess the magnitude of changes across signs and symptoms of atopic dermatitis with lebrikizumab monotherapy over the 16-week induction period in two phase 3 studies, ADvocate1 and ADvocate2.
Methods: Eligible adults (aged ≥ 18 years) and adolescents (aged 12 to < 18 years and weighing ≥ 40 kg) with moderate-to-severe atopic dermatitis were randomized to receive either 250 mg of lebrikizumab or placebo subcutaneously every two weeks. Least squares mean percentage change from baseline through week 16 was compared between lebrikizumab and placebo using mixed model repeated measure analysis for the following endpoints: Eczema Area and Severity Index (EASI), Pruritus Numeric Rating Scale (NRS), Sleep-Loss Scale, Patient-Oriented Eczema Measure (POEM), and Dermatology Life Quality Index (DLQI).
Results: In both trials, significant (P < 0.05) improvements were observed for lebrikizumab treatment compared with placebo at each 2-week timepoint for EASI, Pruritus NRS, Sleep-Loss Scale, and POEM, and at each 4-week timepoint for DLQI, through week 16. Statistically significant (P < 0.001) improvements were observed at 16 weeks for lebrikizumab treatment versus placebo in ADvocate1/ADvocate2 for EASI (71.9%/75.0% vs. 35.6%/43.3%), Pruritus NRS (53.3%/46.3% vs. 21.4%/18.0%), Sleep-Loss Scale (57.7%/55.6% vs. 23.9%/25.5%), POEM (54.4%/45.8% vs. 18.8%/16.9%), and DLQI (64.2%/60.5% vs. 28.5%/32.2%). Patient photos show improvements in skin appearance when disease measures improve.
Conclusions: Lebrikizumab monotherapy resulted in significant and fast improvements in multiple dimensions of disease (clinical signs, symptoms, and quality of life) over 16 weeks in patients with moderate-to-severe atopic dermatitis.
期刊介绍：
Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
