Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Interleukin-6 (IL-6) receptor antagonist; sarilumab binds specifically to both soluble and membrane-bound IL-6 receptors, inhibiting IL-6-mediated signaling through gp130 and STAT3.
Lecanemab is a humanized monoclonal antibody that targets aggregated soluble and insoluble forms of amyloid beta, reducing amyloid plaques in the brain.
