A recent single-center retrospective study has shed new light on the treatment of moderate to severe atopic dermatitis (M2S AD), a chronic inflammatory skin condition marked by intense itching and painful lesions that significantly impair patients’ quality of life. The study compared the effectiveness and safety of three oral medications—cyclosporine, tofacitinib, and the recently approved abrocitinib—over a 16-week period in adult patients.
Atopic dermatitis remains a challenging condition to manage, especially in its moderate to severe forms. Traditional therapies such as cyclosporine have long been used, while tofacitinib, primarily prescribed off-label, has shown promising results. More recently, abrocitinib, a selective Janus kinase 1 (JAK1) inhibitor, gained approval and has been studied mostly in Western populations. However, comparative real-world data among these three treatments have been scarce until now.
The study involved 15 patients divided equally among the three treatment groups. Researchers evaluated the patients at the start and at four-week intervals up to week 16, using widely accepted measures like the Eczema Area and Severity Index (EASI), Scoring Atopic Dermatitis (SCORAD), and the Dermatology Life Quality Index (DLQI). They also assessed patients’ itch severity using a Numerical Rating Scale (NRS) and monitored serum IgE levels, an immune marker often elevated in atopic dermatitis.
Results showed that all three medications significantly improved symptoms and quality of life over the study period. However, abrocitinib demonstrated superior clinical outcomes, with notably greater reductions in EASI, SCORAD, and NRS scores compared to tofacitinib and cyclosporine. Specifically, abrocitinib led to an 87% reduction in EASI scores, outperforming tofacitinib’s 64% and cyclosporine’s 51%. Similar trends were observed in SCORAD and NRS measurements, with abrocitinib achieving reductions of 93% and 85%, respectively. Quality of life improvements, as measured by DLQI, also favored abrocitinib, which showed an 80% improvement compared to 59% and 47% for tofacitinib and cyclosporine. Notably, serum IgE levels decreased significantly only in the abrocitinib group.
Regarding safety, the medications were generally well tolerated. Mild adverse events occurred across all groups, including headaches and nausea among patients on abrocitinib, infections in the tofacitinib group, and hypertension in those taking cyclosporine. Importantly, no severe side effects or treatment discontinuations were reported, and all adverse events resolved during the study.
While the findings suggest that abrocitinib may offer enhanced symptom control over existing treatments, researchers caution that the small sample size limits the generalizability of these results. They emphasize the need for larger, long-term studies to confirm these preliminary observations and to further assess the safety profile of these drugs in diverse patient populations.
This study highlights the evolving landscape of atopic dermatitis treatment, underscoring the potential benefits of newer targeted therapies. As clinicians seek to optimize management strategies for M2S AD, real-world evidence like this provides valuable insights to guide therapeutic decisions and improve patient outcomes.
