Abstract

Objectives: Whether patients with RA benefit from repeated trials of biologic or targeted synthetic DMARDs (b/tsDMARDs) after three or more attempts is unknown. We aimed to describe treatment outcomes in each line of b/tsDMARD therapy.

Methods: Using data from the British Society for Rheumatology Biologics Register for RA from 2001 to 2020, change to a new b/tsDMARD (except biosimilar switches) was defined as a new line of therapy. Treatment outcomes were compared across lines of therapy, including DAS28 remission (≤2.6), low disease activity (LDA, ≤3.2) at 6 months and median time to drug discontinuation. Multiple imputation was used for missing data.

Results: A total of 22 934 individuals starting a first b/tsDMARD were included (mean age 56 years, 76% female), among whom 10 823 commenced a second-line drug, 5056 third, 2128 fourth, 767 fifth and 292 sixth. Most (71%) had sufficient data for DAS28-derived outcome analyses. TNF inhibitors were the most common first-line drug, but choice of subsequent-line drugs changed over time. Seventeen percent achieved DAS28 remission following first-line, 13% second and 8-13% with third through sixth. LDA was achieved in 29% of first-line, 23% second, 17-22% through to the sixth. Patients stayed on first-line therapy for a median of 2.6 years, ranging from 1.0-1.4 years for lines two to six.

Conclusion: Many patients will eventually benefit after repeated trials of b/tsDMARD. Further research to improve treatment selection are needed to prevent prolonged trial and error approaches in some patients.

Pattern of sequential therapy Each column represents one line of treatment, with length proportional to absolute numbers. TNF, tumour necrosis factor inhibitor; CD20, rituximab is the only example of B cell depletion therapy; CTLA4, abatacept is the sole CTLA4 immunoglobulin; IL6, IL-6 inhibitor; JAK, janus kinase inhibitor; IL1, anakinra is the sole IL-1 inhibitor.
