Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lecanemab is a humanized monoclonal antibody that targets aggregated soluble and insoluble forms of amyloid beta, reducing amyloid plaques in the brain.
Bezlotoxumab is a human monoclonal antibody that binds to Clostridioides difficile toxin B, neutralizing its activity and preventing damage to colonic epithelial cells.
