Sarilumab (trade name Kevzara) is a human monoclonal antibody against the interleukin-6 receptor. Regeneron and Sanofi developed the drug for the treatment of rheumatoid arthritis (RA), for which it received US FDA approval on 22 May 2017 and European Medicines Agency approval on 23 June 2017.
Sarilumab is used for the treatment of moderately to severely active rheumatoid arthritis in people who have not responded to, or did not tolerate, more conventional treatments. It can be used alone or in combination with methotrexate or other disease-modifying antirheumatic drugs (DMARDs).
In Europe, sarilumab is contraindicated in people with active, severe infections. While this is not listed as a contraindication under the US FDA approval, there is a boxed warning that recommends testing for hidden tuberculosis infection before treatment and monitoring for signs of an infection during therapy with sarilumab.
The MONARCH trial suggested a significantly higher incidence of neutropenia in patients receiving 200 mg sarilumab every 2 weeks, compared to patients being treated with adalimumab (13.6% vs 0.5%). However, infection rates were similar between both groups (28.8% vs 27.7%).
Other common side effects that occurred in 1% to 10% of patients included thrombocytopenia (low platelet count), infections of the upper respiratory tract and the urinary tract, oral herpes, hyperlipidaemia, and reactions at the injection site.
On May 15, 2013, both companies announced that 2 new trials were starting (COMPARE and ASCERTAIN) and the first patients had already been enrolled.
In Nov 2015, the SARIL-RA-TARGET trial reported good results (meeting both its coprimary end points).
