Upadacitinib exhibits Efficacy and High Retention in Atopic Dermatitis Treatment, reveals study

The study team conducted a retrospective analysis based on data obtained from the Royal Melbourne Hospital's BioGrid Database and electronic medical records. Participants were adults aged 18 years and above with moderate-to-severe chronic atopic dermatitis who had at least one upadacitinib prescription via PBS or a Compassionate Supply program. Patient demographics, comorbidities, EASI scores, Dermatology Life Quality Index (DLQI) scores, and previous treatments were collected.

The main outcome was treatment persistence, defined as the time from upadacitinib initiation until discontinuation, switch to a different biologic, or death. Reasons for discontinuation were closely recorded, including factors such as side effects, infections, practical barriers, failure to respond, or secondary loss of response.

Key Findings

The results of the study showed excellent treatment retention with upadacitinib in clinical practice:

• 90.5% of the patients were still on upadacitinib at week 4, reflecting a very high short-term rate of medication continuation.

• Discontinuations were due to many reasons, such as adverse events, infections, loss of efficacy, and logistical issues.

• 50% of 14 patients who had switched from dupilumab to upadacitinib reported loss of efficacy as the primary reason for switching, and 28.6% switched because dupilumab was completely not effective.

• The research established that loss of treatment effect was most commonly identified by patients and corroborated by dermatologists with clinical indicators like increasing EASI scores.

• Patient variables at baseline were the variables like comorbid asthma, history of smoking, and previous use of biologics, but none of these had a strong influence on persistence rates in the short term.

This real-world analysis in Australia showed that upadacitinib has high treatment retention rates among moderate-to-severe atopic dermatitis patients, 90.5% at 4 weeks. Loss of efficacy was the most common reason for discontinuation, especially among dupilumab-pretreated patients. The results are helpful for clinicians selecting biologic therapies and support the practical, long-lasting place for upadacitinib in the treatment of atopic dermatitis.
