Abstract
ObjectiveThis real-world analysis assessed baseline demographics/characteristics and treatment patterns/effectiveness in patients with rheumatoid arthritis (RA) initiating tofacitinib (TOF) in the US CorEvitas RA Registry.MethodsThe primary analysis of this study included patients with RA initiating TOF with a 12-month follow-up visit from November 2012 to January 2021. Outcomes included baseline demographics/characteristics and TOF initiation/discontinuation reasons, treatment patterns, and effectiveness (disease activity and patient-reported outcomes [PROs] at 12 months); the primary effectiveness outcome was Clinical Disease Activity Index low disease activity (CDAI LDA). All data, analyzed descriptively, were stratified by TOF regimen (monotherapy vs combination therapy), line of therapy (second- to fourth-line), time of initiation (2012-2014, 2015-2017, or 2018-2020), and dose (5 mg twice daily vs 11 mg once daily).ResultsOf 2874 patients with RA who initiated TOF, 1298 had a qualifying 12-month follow-up visit; of these, 43.1% were monotherapy and 66.5% were fourth-line therapy. Overall, tumor necrosis factor inhibitors (40.8%) were the most common treatment immediately prior to TOF initiation. The most common reason for TOF initiation (among those with a reason) was lack/loss of efficacy of prior treatment (67.7%). Overall, at 12 months, 31.9% and 10.1% had achieved CDAI LDA and remission, respectively; 22.4%, 10.4%, and 5% had achieved ≥ 20%, ≥ 50%, and ≥ 70% improvement in modified American College of Rheumatology core set measures, respectively; and improvements in PROs were observed. Effectiveness was generally similar across TOF stratifications.ConclusionTOF effectiveness (CDAI LDA) was observed in a US real-world setting of patients with RA regardless of TOF regimen, line of therapy, time of initiation, and dose.
