Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Daclizumab is a humanized monoclonal antibody that binds to the alpha subunit (CD25) of the high-affinity interleukin-2 (IL-2) receptor on activated T cells. By blocking IL-2 binding, it inhibits IL-2-mediated activation and proliferation of lymphocytes, which are involved in the pathogenesis of multiple sclerosis.
Bezlotoxumab is a human monoclonal antibody that binds to Clostridioides difficile toxin B, neutralizing its activity and preventing damage to colonic epithelial cells.

Terminal half-life approximately 21 days (range 18-27 days) following subcutaneous administration, supporting monthly dosing interval.
Mean terminal elimination half-life is approximately 19 days (range 14–22 days), supporting a 6-week dosing interval.
Excreted primarily via proteolytic catabolism; not renally or hepatically eliminated. No specific biliary/fecal data available.
Primarily eliminated via fecal excretion as unchanged drug (approximately 79% of dose), with minimal renal excretion (about 15% as unchanged drug).
