TOPLINE:
The use of newer biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) for treating juvenile idiopathic arthritis (JIA) rose sharply from 2001 to 2022, while the use of conventional synthetic DMARDs (csDMARDs) plummeted, with adalimumab becoming the most commonly used b/tsDMARD.
METHODOLOGY:
- Researchers performed a serial cross-sectional study using Merative MarketScan Commercial Claims and Encounters data from 2000 to 2022 to describe recent trends in DMARD use for children with JIA in the United States.
- They identified 20,258 new episodes of DMARD use among 13,696 children with JIA (median age, 14 years; 67.5% girls) who newly initiated at least one DMARD.
- Participants were required to have ≥ 365 days of continuous healthcare and pharmacy eligibility prior to the index date, defined as the date of DMARD initiation.
TAKEAWAY:
- The use of csDMARDs declined from 89.5% to 43.2% between 2001 and 2022 (P < .001 for trend), whereas the use of bDMARDs increased from 10.5% to 50.0% over the same period (P < .001).
- Methotrexate was the most commonly used DMARD throughout the study period ; however, as with other csDMARDs, its use declined from 42.1% in 2001 to 21.5% in 2022 (P < .001 ).
- Use of the tumor necrosis factor inhibitor adalimumab doubled from 7% in 2007 to 14% in 2008 and increased further up to 20.5% by 2022; adalimumab also became the most predominantly used b/tsDMARD after csDMARD monotherapy, accounting for 77.8% of prescriptions following csDMARDs in 2022.
- Even though the use of individual TNF inhibitors increased, their overall popularity fell in recent years as the use of newer b/tsDMARDs, such as ustekinumab and secukinumab, increased.
IN PRACTICE:
“These real-world treatment patterns give us insight into how selection of therapies for JIA has evolved with increasing availability of effective agents and help prepare for future studies on comparative DMARD safety and effectiveness,” the authors wrote.
SOURCE:
The study was led by Priyanka Yalamanchili, PharmD, MS, Center for Pharmacoepidemiology and Treatment Science, Institute for Health, Rutgers University, New Brunswick, New Jersey, and was published online October 22, 2024, in Arthritis & Rheumatology.
LIMITATIONS:
The dependence on commercial claims data may have limited the generalizability of the findings to other populations, such as those with public insurance or without insurance. The study did not have access to demographic data of the participants to investigate the presence of disparities in the use of DMARDs. Moreover, the lack of clinical details about the patients with JIA, including disease severity and specialty of prescribers, may have affected the interpretation of the results.
DISCLOSURES:
The study was supported by funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and several other institutes of the National Institutes of Health, as well as the Rheumatology Research Foundation and the Juvenile Diabetes Research Foundation. No conflicts of interest were reported by the authors.
