,” the study’s lead author, Jonathan I. Silverberg, MD, PhD, MPH, reported.
The findings come from an analysis of real-world outcomes from the TARGET-DERM AD registry, which Dr. Silverberg, professor and director of clinical research and contact dermatitis in the department of dermatology at George Washington University, Washington, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. He characterized the findings as “patients just getting stuck with a therapy and not advancing when they need to.”
TARGET-DERM AD is a longitudinal observational study of people with AD at 39 academic centers in the United States and Canada. Dr. Silverberg and his coinvestigators evaluated the proportion of patients who were experiencing an inadequate response after receiving systemic therapy and continuing on the same treatment for 3-12 months. “These are patients who are receiving their first or advanced systemic therapy, and the question is, how long did they stay on it, even if they’re not doing so well?” Dr. Silverberg said.

The researchers identified and compared the proportions of patients not achieving moderate or optimal clinician-reported outcome targets on patients with AD treated with their first systemic therapy. Advanced systemic therapy (AST) included abrocitinib, dupilumab, tralokinumab, or upadacitinib, while conventional systemic therapy (CST) included methotrexate, cyclosporine, mycophenolate mofetil, azathioprine, and systemic corticosteroids.
Patients in TARGET-DERM AD were treated and maintained on their first systemic therapy (either advanced or conventional) for up to 12 months. They had a validated Investigator’s Global Assessment of AD (vIGA-AD) score of 3 or 4 less than 45 days prior to initiation of systemic therapy or up to 14 days afterward. They also had at least one vIGA-AD assessment 3-12 months after initiating treatment. Outcome measures included IGA (defined as a score of 2 or less, with an optional target of 0 or 1), BSA (defined as a 50% BSA improvement, with an optimal target BSA of 2% or less), and the Worst-Itch Numeric Rating Scale (defined as at least a 4-point reduction, with an optimal target of 1 or less).
The analysis included 445 patients with a mean age of 31 years at enrollment. More than half (62%) were female and 45% were non-Hispanic Whites. Most patients (92%) were on an AST, mainly dupilumab, with smaller proportions treated with either tralokinumab, upadacitinib, or abrocitinib. Fewer than 10% of patients in the registry were being treated with CSTs.
At 6 months, 37% and approximately 67% of the AST-treated patients had inadequate responses in terms of skin clearance and itch outcomes, respectively. At 12 months, these figures were about 30% and 66%, respectively. CST-treated patients showed a similar trend. For patients starting an AST on or after Sept. 21, 2021, when three additional AST options were available (tralokinumab, upadacitinib, and abrocitinib), the proportion of patients demonstrating an adequate response over 12 months was generally similar to the overall cohort of those on ASTs.
“These findings suggest a need for alternative therapies and management strategies in AD treatment,” concluded Dr. Silverberg, who chaired the RAD symposium.
