Abstract
BACKGROUND
As an evidence resource for the currently planned European Academy of Allergy and Clinical Immunology (EAACI) clinical practice guideline "systemic treatment of atopic dermatitis (AD)," we critically appraised evidence on systemic treatments for moderate-to-severe AD.
METHODS
We systematically identified randomized controlled trials (RCTs) investigating the safety and efficacy of systemic treatments for AD up to February 2020. Primary efficacy outcomes were clinical signs, AD symptoms and health-related quality of life. Primary safety outcomes included cumulative incidence rates for (serious) adverse events. Trial quality was assessed applying the Cochrane Risk of Bias Tool 2.0. Meta-analyses were conducted where appropriate.
RESULTS
50 RCTs totalling 6681 patients were included. Trial evidence was identified for apremilast, azathioprine (AZA), baricitinib, ciclosporin A (CSA), corticosteroids, dupilumab, interferon-gamma, intravenous immunoglobulins (IVIG), mepolizumab, methotrexate (MTX), omalizumab, upadacitinib and ustekinumab. Meta-analyses were indicated for the efficacy of baricitinib [EASI75 RD 0.16, 95% CI (0.10;0.23)] and dupilumab [EASI75, RD 0.37, 95% CI (0.32;0.42)] indicating short-term (ie 16-week treatment) superiority over placebo. Furthermore, efficacy analyses of AZA and CSA indicated short-term superiority over placebo; however, nonvalidated scores were used and can therefore not be compared to EASI.
CONCLUSION
The most robust, replicated high-quality trial evidence is present for the efficacy and safety of dupilumab for up to 1 year in adults. Robust trial evidence was further revealed for AZA, baricitinib and CSA. Methodological restrictions led to limited evidence-based conclusions for all other systemic treatments. Head-to-head trials with novel systemic treatments are required to clarify the future role of conventional therapies.
