Patients with moderate to severe atopic dermatitis (AD) affecting between 10% and 50% of their body surface area (BSA) account for the majority of responders to baricitinib 2 mg, results from an analysis of phase 3 data showed.
"This proposed clinical tailoring approach for baricitinib 2 mg allows for treatment of patients who are more likely to respond to therapy and rapid decision on discontinuation of treatment for those who are not likely to benefit from baricitinib 2 mg," Eric L. Simpson, MD, said during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis virtual symposium.
Baricitinib is an oral, reversible and selective Janus kinase 1/JAK2 inhibitor that is approved in Europe for the treatment of moderate to severe AD in adults who are candidates for systemic therapy. In the United States, it is approved for treating rheumatoid arthritis, and is currently under Food and Drug Administration review in the United States for AD.
For the current analysis, Simpson, professor of dermatology at Oregon Health & Science University, Portland, and colleagues set out to identify responders to baricitinib 2 mg using a tailored approach based on baseline BSA affected and early clinical improvement in the phase 3 monotherapy trial BREEZE-AD5
