Background: Decision to initiate a new systemic therapy (ST) among patients with atopic dermatitis (AD) is complex. This cross-sectional study explored overall disease burden, sociodemographic and clinical characteristics, and disease activity among patients with moderate-to-severe AD.

Methods: Adult patients with AD who had a vIGA-ADTM score ≥3 and Eczema Area Severity Index (EASI) score ≥12 at enrollment were identified from the prospective, longitudinal CorEvitas AD Registry between 07/21/2020 and 12/31/2022. Included patients were newly prescribed an eligible ST (ST group) or not prescribed an eligible ST (non-ST group) at enrollment. Patients on ST before enrollment were excluded. Sociodemographic characteristics, disease features, severity measures (vIGA-ADTM [0–4]; body surface area (BSA) [0–100%]; EASI [0–72]), and patient-reported outcomes (PROs) were assessed. PROs included Dermatology Life Quality Index (DLQI) [0-30], Itch/Pruritus Numeric Rating Scale [0-10], Patient-Oriented Eczema Measure (POEM) [0-26], and AD Control Tool (ADCT) [<7 controlled, >7 not controlled]. Differences in means or proportions of characteristics among ST and non-ST groups were summarized using effect sizes (ES).

Results: The study included 673 (mean age=50.7 years, 55.6% female) patients who were newly prescribed ST and 229 (47.8 years, 51.3%) who were not prescribed ST. The overall distribution of race (Whites 70.4% vs. 60.5%, Asians 8.6% vs. 17.5%, Black 13.7% vs. 8.3%, Other 7.3% vs. 13.6%; ES=0.17) and geographic region (West 8.5% vs. 28.4%, South 32.1% vs. 15.7%; ES=0.27) had small differences between the ST and non-ST groups. More patients (n=402 [59.7%]) in the ST group had severe AD (vIGA-ADTM=4), whereas moderate AD (vIGA-ADTM=3) was more common (n=137 [59.8%]) in the non-ST group. Higher disease severity was reported in the ST group versus non-ST group: BSA (mean [SD]: 41.6% [17.1] vs. 31.5% [16.0]; ES=0.61) and EASI (24.3 [10.1] vs. 19.8 [8.6]; ES=0.47). Mean [SD] PRO measures were also higher in the ST group compared to non-ST group: DLQI (11.7 [7.5] vs. 10.4 [7.9]; ES=0.17), mean peak pruritus in the past 24 hours (6.8 [2.9] vs. 6.1 [3.1]; ES=0.25), POEM (17.8 [7.1] vs. 16.6 [7.5]; ES=0.17), and ADCT (14.4 [6.1] vs. 13.0 [6.7]; ES=0.21).

Conclusion: Patients not initiating ST have high rates of severe, uncontrolled AD, and considerable burden from their disease, indicating potential delayed or undertreatment. Understanding the factors that influence the decision to escalate therapy in systemic-eligible patients is important for improving care of AD.
