CRYSVITA vs RAXIBACUMAB
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fibroblast growth factor 23 (FGF23) inhibitor; increases renal phosphate reabsorption and 1,25-dihydroxyvitamin D production by blocking FGF23 activity.
Raxibacumab is a monoclonal antibody that binds to the protective antigen (PA) component of Bacillus anthracis toxins, preventing PA from binding to host cell receptors and thereby inhibiting the intracellular entry of lethal factor and edema factor. This neutralizes the lethal and edema toxins, reducing pathogenicity.
1 mg/kg subcutaneously once monthly; maximum dose 90 mg. Administer at a fixed date each month.
Single intravenous dose of 40 mg/kg administered over 30 minutes.

16.4 days (terminal elimination half-life); supports monthly subcutaneous dosing.
Terminal elimination half-life approximately 12-24 hours (mean ~18 hours) in patients with normal renal function; half-life extends in renal impairment.
Renal (minimal, as intact antibody); catabolized into small peptides and amino acids; no biliary/fecal elimination of intact drug.
Primarily renal excretion as intact protein; >90% of administered dose recovered in urine over 48 hours.
