This real-life study confirms findings from the tocilizumab (TCZ) clinical development program that IL-6 inhibition with TCZ may be associated with increased risk of lower intestinal perforation (LIP). Data were analysed from the RABBIT register of patients. The primary outcome was the incidence of LIPs in patients exposed to TCZ, csDMARDs, TNFis, abatacept, or rituximab. Thirty-seven LIPs were observed in 53,972 patient years. The proportion of patients who developed a LIP was higher in patient...
This study pools data from the global tofacitinib RA development programme (phase II, phase III and long-term extension studies) to determine the rate of infections and all-cause mortality with tofacitinib treatment. In total, 4,789 patients within these studies received tofacitinib, at varying doses and with varying duration.

The overall incidence rate of serious infections was 3.09 events/100 patient-years (95% CI 2.73–3.49), which was stable over time, with pneumonia and skin and soft...

Two systematic literature reviews were undertaken to update the safety findings on synthetic and biological DMARDs in order to inform the updates to the EULAR recommendations to the treatment of RA. Of 10,559 articles screened, 49 were included for review covering a diverse range of outcomes. In the main these showed the patients on bDMARDs had a significantly greater risk of serious infections and tuberculosis compared with csDMARDs, while differences in data between studies mean a slight incre...
