645 - Effectiveness and safety of upadacitinib in adolescent and adult patients with atopic dermatitis: an analysis of long-term (week 52) data from a real-world multicenter retrospective review
Notice bibliographique
Résumé
Abstract Introduction While clinical trial data demonstrates the efficacy and safety of upadacitinib (UPA), an oral Janus kinase inhibitor (JAKi) for atopic dermatitis (AD), long-term real-world evidence remains limited. Objectives Our study evaluated the real-world effectiveness and safety of UPA for AD at week 52±6. Methods We conducted a multicenter retrospective review of 3 practices in Canada. Effectiveness endpoints were evaluated at weeks 52±6 and including the following: Investigator Global Assessment (IGA) score of clear or almost clear (IGA 0/1) as well as improvements in Eczema Area and Severity Index (EASI), body surface area (BSA), IGAxBSA, and Dermatology Life Quality Index (DLQI)/Children’s DLQI (CDLQI). Safety was determined via incidence of treatment-related adverse events (AEs). Results A total of 102 patients with AD were included in the analysis; mean age was 44.2 (range: 12-79) years and 52.9% (54/102) were female. Initial UPA doses were 15 mg (UPA15: 41.2%, 42/102) or 30 mg (UPA30: 58.8%, 60/102) once daily. Previous systemic therapies included conventional non-biologics (72.5%), biologics (30.4%), and JAKi (2.9%). At week 52±6: 78.4% (80/102) of patients achieved Investigator Global Assessment (IGA) 0/1; 87.5% (49/56), 78.6% (44/56), and 50.0% (28/56) achieved Eczema Area and Severity Index (EASI) improvements of 75% (EASI75), 90% (EASI90), and 100% (EASI100), respectively; 75.0% (42/56) achieved EASI90 + IGA 0/1; mean EASI was reduced from 12.9 to 0.8 (mean EASI improvement = 91.4%); 91.9% (52/56), 92.9% (52/56), 82.1% (46/56), and 75.0% (42/56) achieved absolute EASI scores <7, <5, <3, and <1, respectively; mean body surface area (BSA) was reduced from 17.0% to 0.6% (mean BSA improvement=87.8%); mean IGAxBSA was reduced from 52.1 to 0.8 (mean IGAxBSA improvement=90.7%); and mean Dermatology Life Quality Index (DLQI)/Children’s DLQI was reduced from 13 to 1.8 (mean DLQI/CDLQI improvement=86%), with 66.0% (33/50) of patients achieving DLQI/CDLQI 0/1. For patients not achieving IGA 0/1, EASI75, EASI90, and EASI100 at weeks 8-20, these responses were subsequently achieved in 60.0% (6/10), 88.9% (8/9), 84.6% (11/13), and 38.1% (8/21) of patients at week 52±6. Dose alterations occurred in 13 patients (12.7%) (escalation: 6.9%, 7/102; reduction: 5.9%, 6/102). Concomitant systemic therapies were used in 1.0% (1/102) of patients. We noted higher statistically significant achievement of endpoints for systemic biologic/JAKi-naïve vs -experienced patients (EASI75; EASI<7; EASI<5; DLQI/CDLQI >4-point improvement). No significant differences in outcomes were identified between dosing regimens. Frequent AEs included: acne (19.6%, 20/102), hypertriglyceridemia (17.6%, 18/102), elevated creatine phosphokinase (13.7%, 14/102), neutropenia (7.8%, 8/102), and transaminitis (7.8%, 8/102). Seven patients (6.8%) discontinued UPA owing to treatment-related AEs, including one case of venous thromboembolism; four patients (3.9%) discontinued UPA due to patient preference, and one patient (1%) discontinued UPA due to lack of efficacy. No serious infections, tuberculosis, major adverse cardiovascular events, gastrointestinal perforation, malignancy, or deaths were observed in 102.5 patient-years of follow-up. Conclusions In contrast to 52-week data from the Measure Up 1/2 and AD Up clinical trials, our results were superior for several outcome parameters (IGA 0/1, EASI90, EASI100, and DLQI 0/1), possibly owing to a patient population with less extensive baseline disease severity. Additionally, we noted similar achievement of these endpoints versus comparable long-term real-world studies. Safety was consistent with existing data, highlighting acne as a common AE (5.3%-20.3% versus 19.6%). Study limitations include its sample size and retrospective nature.
