, results from an analysis of registry data showed.
“We know from clinical trials that upadacitinib is effective, but we have very little real-world experience on its effectiveness,” presenting study author Melinda Gooderham, MD, medical director of the Skin Center for Dermatology in Peterborough, Ontario, Canada, said during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.
For the analysis, she and her coauthors evaluated the real-world clinical and patient-reported outcomes of 335 adults enrolled in the CorEvitas AD Registry from July 21, 2020, through Aug. 7, 2023. They included patients who were on upadacitinib for at least 4 weeks and persisted on the drug until the time of evaluation.
The CorEvitas AD Registry is a prospective, non-interventional registry of adults diagnosed with AD by a dermatologist or qualified dermatology practitioner. Outcomes measures included the proportion of patients who achieved skin clearance as defined by a Validated Investigators Global Assessment Scale for Atopic Dermatitis (vIGA) score of 0 or 1, an Eczema Area and Severity Index (EASI) score of 3 or less, a Peak Pruritus Numeric Rating Scale (PP-NRS) score of 0 or 1, Patient-Oriented Eczema Measure (POEM) scores of 0-2, Dermatology Life Quality Index (DLQI) scores of 0 or 1, or an Atopic Dermatitis Control Tool (ADCT) score of <7.
The researchers evaluated cross-sectional data from three different cohorts: data from the last registry visit (the overall cohort), data from a visit within 1 month to less than 5 months of upadacitinib initiation (the 1-5 months cohort), and data from a visit within 5-9 months following upadacitinib initiation (the 5-9 months cohort). They also conducted subgroup analyses of patients with prior use of biologics for AD (bio-experience) and those with no such history (bio-naive). Safety events were not assessed in this analysis.
The mean age of the 335 patients was 45.6 years, 51.6% were female, 64.2% were White, 64.2% were based in the United States and the rest were based in Canada. Most patients (70.8%) were treated with the 15-mg dose of upadacitinib. The median duration of treatment was 6.9 months. Slightly more than one-quarter of patients (28.1%) reported concomitant use of topical corticosteroids for AD, while 45.4% reported prior use of dupilumab and 6% reported prior use of tralokinumab.
Dr. Gooderham reported that 57.5% of patients in the total cohort total cohort achieved clear or almost clear skin (a vIGA-AD score of 0 or 1), with slight differences between the bio-naive (60.6%) and bio-experienced (54.1%) subgroups.
The other outcomes were similarly close between the 176 bio-naive and 159 bio-experienced patients. Specifically, 74.8% in the total cohort, 79.4% in the bio-naive subgroup, and 69.6% in the bio-experienced subgroup achieved an EASI score of 3 or less. In the measure of the worst itch in the past 24 hours, 45.3%, 47.7%, and 42.8% respectively achieved a PP-NRS of 0 or 1. In the patient-reported disease burden, 36.4%, 41%, and 31.4% achieved a POEM score of 0-2. In the quality of life measure, 39.8%, 42.8%, and 36.5% achieved a DLQI score of 0 or 1. In the measure of disease control, 69.3%, 70.5%, and 67.9% achieved an ADCT score of <7. In a combination of skin clearance and itch control, 40.9%, 43.2%, and 38.4% of the total cohort, bio-naive, and bio-experienced respectively achieved both an EASI score of 3 or less and a PP-NRS of 0 or 1.
The study outcomes were similar between the 1-5 months cohort and the 5-9 months cohort, but there was a trend toward more clearance the longer patients were on therapy.
“The findings suggest that low levels of disease severity are observed in patients on upadacitinib in a real-world setting,” Dr. Gooderham concluded. “This confirms what we see in the clinical trials.”
