Dupilumab is a subcutaneous injection therapy that inhibits the interleukin 4 receptor alpha subunit. It has been approved in the United States for the treatment of adults with moderate-to-severe AD since 2017 and has since been approved for children and adolescents older than 6 years. Many real-world studies of the effectiveness of dupilumab have been published over the past few years. Kojanova and colleagues reported findings from a retrospective, multicenter study of 360 adults with severe AD who received dupilumab. They found that a high proportion of patients achieved a 75% improvement in the Eczema Area and Severity Index (EASI-75) at week 16 (66.6%), 1 year (89.5%), and 2 years (95.8%). Drug persistence rates were very high (> 90%) throughout the 2 years of therapy, suggesting that dupilumab was effective and well-tolerated.
Dupilumab was previously found to be associated with increased conjunctivitis in clinical trials and real-world studies. Schneeweiss and colleagues conducted a population-based longitudinal study of 5,004,117 patients with AD who newly initiated dupilumab, methotrexate, mycophenolate, and cyclosporine. They found that the risk of developing conjunctivitis diagnosed in clinical practice within 6 months of treatment initiation was approximately double with dupilumab compared with methotrexate, mycophenolate, or cyclosporine. Interestingly, comorbid asthma was found to be a risk factor for conjunctivitis in dupilumab initiators. This study provides insight into how commonly clinically significant conjunctivitis occurs with dupilumab treatment. Of note, the study results may underestimate the incidence of conjunctivitis because milder cases may go undetected.
Upadacitinib is an oral selective Janus kinase (JAK) 1 inhibitor that was approved in the United States in 2022 for the treatment of moderate-to-severe AD. Simpson and colleagues reported on the long-term efficacy and safety of oral upadacitinib from the phase 3 double-blind, randomized controlled trials Measure Up 1 and Measure Up 2 in adolescents and adults with moderate-to-severe atopic dermatitis ho had an inadequate response to topical therapy. The initial phase of the Measure Up 1 and Measure Up 2 studies was 16 weeks in duration, with a placebo control group. At week 16, patients who received 15 or 30 mg upadacitinib in the initial 16 weeks of the study continued to receive that dose. Patients who received placebo in the initial 16 weeks were randomly assigned to receive oral 15 mg or 30 mg upadacitinib daily. So, in the long run, all patients received upadacitinib in the second phase of the study but were blinded to the dose they were receiving. The results from the first 16 weeks of treatment were previously published. Simpson and colleagues reported on the results up to week 52 from the second phase of the study. They showed that at week 52, 82.0% and 79.1% of patients in Measure Up 1 and Measure Up 2 achieved a 75% improvement in EASI-75 when continuing on 15 mg upadacitinib and 84.9% and 84.3% in patients continuing 30 mg upadacitinib, respectively. More than 80% of patients who switched from placebo to upadacitinib at week 16 achieved EASI-75 at week 52. No safety signals were observed in this phase of the study that were not previously observed in other studies of upadacitinib for atopic dermatitis and other indications (rheumatoid arthritis and psoriatic arthritis). These results indicate that upadacitinib has durable efficacy with long-term treatment in moderate-to-severe AD. These studies are ongoing, and I look forward to future results reporting for even longer-term treatment.
It is an exciting time in dermatology with the arrival of multiple novel therapies for atopic dermatitis. The field has already benefited so much by the tremendous interest and research effort into understanding how to best manage this disease. With so many more treatments in the pipeline, perhaps the best is yet to come.
