Comparative effectiveness of subcutaneous sarilumab 200 mg biweekly, subcutaneous Tocilizumab 162 mg biweekly, and intravenous Tocilizumab 8 mg/kg every 4 weeks in patients with rheumatoid arthritis: a prospective cohort study.

ABSTRACT:

Background

While targeting the interleukin-6 receptor (IL-6R) through the use of sarilumab (SAR) or tocilizumab (TCZ) has become a major therapeutic approach for rheumatoid arthritis (RA), direct comparisons between IL-6R inhibitors (IL-6Ris) for treating RA have not been conducted. We aimed to compare the effectiveness of subcutaneous sarilumab (SAR-SC), subcutaneous tocilizumab (TCZ-SC), and intravenous TCZ (TCZ-IV) against RA in a multicenter cohort study.

Methods

Within the target trial emulation framework, an incident new-user and active-comparator cohort design was used. The source population was the entire cohort of a multicenter prospective study (the ANSWER cohort study) in Japan from 2009 to 2023. We consecutively included patients with IL-6Ri-naïve RA who initiate
