Objectives

Narrative objectives1

The efficacies of tofacitinib and abatacept in rheumatoid arthritis (RA) in clinical practice is compared in multicenter trials. Comparisons are made using propensity score matching to eliminate the effects of selection bias and confounding factors in observational studies. In addition, we analyze HLA-DRB1 alleles of target patients and investigate the influence of shared epitopes on the therapeutic effect of each drug.

Assessment

Primary outcomes

Comparison of DAS28-ESR remission rates between tofacitinib (TOF) and abatacept (ABT) at 6 months after initiation of treatment

Key secondary outcomes

1. Comparison of RA disease activity (changes in DAS28-ESR, SDAI and CDAI scores and EULAR response criteria) between the TOF nd ABT groups at 6 months of treatment initiation.
2. Comparison of RA disease activity (changes in DAS28-ESR, SADI and CDAI scores and EULAR response criteria) and changes in total Sharp score and HAQ-DI between the TOF and ABT groups at 12 months after the initiation of treatment.
3. Analysis of retention rates in the TOF and ABT groups up to 12 months after administration.
4. Analysis of factors contributing to DAS28-ESR remission at 6 months after treatment initiation in the TOF and ABT groups.
5. Analysis of the influence of shared epitopes on DAS28-ESR remission in the TOF and ABT groups at 6 months after treatment initiation.

Results

There was no significant difference in the proportion of patients achieving DAS28-ESR remission between the TOF and ABT groups at week24, while change in DAS28-ESR from baseline to week4 was significantly greater in TOF than in ABT. Analysis of EULAR response at week 24 showed that the proportion of patients who achieved a good EULAR response in TOF group was not affected by number of SE copies, whereas in ABT group it was increased significantly with increasing number of SE copies.
