Drug Overview
Sarilumab (Sanofi/Regeneron) is a human monoclonal antibody interleukin (IL)-6 receptor antagonist in Phase III development for rheumatoid arthritis. IL-6 is a pro-inflammatory cytokine which plays an essential role in a wide variety of biological functions, including the final differentiation of B cells into immunoglobulin-secreting cells, as well as inducing myeloma/plasmacytoma growth and nerve cell differentiation.
Analyst Outlook
Sarilumab’s (Sanofi/Regeneron) clinical performance to date has been comparable to that of the first-to-market interleukin (IL)-6 inhibitor Actemra (tocilizumab; Chugai/Roche). Interviewed rheumatologists highlight that sarilumab’s lack of differentiation from its marketed competitor will prevent it from capturing significant share. Datamonitor Healthcare believes that unless sarilumab demonstrates superior efficacy in certain patient subgroups, and/or has a lower cost, its uptake in rheumatoid arthritis (RA) will be low as Actemra will remain rheumatologists’ IL-6 inhibitor of choice.
