Upadacitinib Outperforms Dupilumab in Treating Atopic Dermatitis: Study
Researchers have found that upadacitinib (Rinvoq) was more effective than dupilumab (Dupixent) in treating moderate-to-severe atopic dermatitis in a phase 3b/4 trial, according to data from the LEVEL UP trial announced on April 25, 2024. The study demonstrated that a greater proportion of patients achieved relief and resolution of symptoms with upadacitinib than with dupilumab. This was announced by AbbVie and was conducted by Jonathan Silverberg, MD, PhD, MPH, director of clinical research and professor of dermatology at the George Washington University School of Medicine and Health Science.
Atopic dermatitis (AD) is a chronic skin condition that can significantly impact patients' quality of life. Both dupilumab and upadacitinib have become important treatments in managing AD, providing options for patients who do not respond adequately to other therapies. The LEVEL UP trial was initiated in 2022 to compare the effects of these agents and guide clinicians in their decision-making.
The LEVEL UP trial included patients aged 12 years and older with moderate-to-severe AD. Participants underwent a 16-week treatment period, followed by an additional 16-week period of treatment with protocol-defined adjustments. The primary endpoint was achieving both a 90% reduction in the Eczema Area and Severity Index (EASI 90) and a Worst Pruritus Numerical Rating Scale of 0 or 1 (WP-NRS 0/1) at the 16-week mark.
Patients in the trial received either upadacitinib starting at 15 mg daily (escalated to 30 mg based on response) or dupilumab at 600 mg initially, followed by 300 mg every two weeks for subjects weighing ≥60 kg. Those weighing less than 60 kg received an initial dose of 400 mg, followed by 200 mg every two weeks.
The key findings of the study were:
• A significantly higher percentage of upadacitinib-treated patients achieved the primary endpoint compared to those treated with dupilumab (19.9% vs 8.9%, P < .0001).
• Upadacitinib also outperformed dupilumab in terms of EASI 90 (40.8% vs 22.5%, P < .0001) and WP-NRS of 0/1 (30.2% vs 15.5%, P < .0001) at the 16-week mark.
• The safety profile of upadacitinib was consistent with previous AD studies, with no new safety concerns identified.
• Both medications had a similar rate of serious adverse events (0.9%).
The results from the LEVEL UP trial suggest that upadacitinib may be a more effective treatment option than dupilumab for patients with moderate-to-severe AD. This can help guide clinicians in selecting the most effective treatments for their patients.
The LEVEL UP trial provides evidence that upadacitinib outperforms dupilumab in treating moderate-to-severe atopic dermatitis, offering higher rates of symptom relief and skin clearance. The safety profile of upadacitinib remains consistent with previous studies, making it a promising option for AD management.
