MIRALUMA vs PHOSPHOTOPE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
MIRALUMA (garadacimab) is a monoclonal antibody that binds to activated factor XII (FXIIa) and inhibits its activity, thereby blocking the contact activation pathway of the coagulation cascade. This prevents the generation of bradykinin, reducing vascular permeability and swelling in hereditary angioedema (HAE).
Unknown; proposed to normalize phosphate metabolism and inhibit ectopic calcification by binding to calcium and phosphate.
MIRALUMA (mirvetuximab soravtansine) is administered intravenously at 6 mg/kg adjusted ideal body weight (AIBW) once every 3 weeks until disease progression or unacceptable toxicity.
10-20 mcg/kg intravenous bolus over 1-2 minutes, may repeat every 10-20 minutes as needed for hemodynamic support. Maximum total dose: 1 mg.

20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Terminal elimination half-life: 4-6 hours in patients with normal renal function; prolonged to 12-24 hours in moderate renal impairment (CrCl <30 mL/min) and >24 hours in dialysis-dependent patients.
90% renal as unchanged drug; 10% biliary/fecal
Renal: 70-80% as unchanged drug; fecal: 15-20% as metabolites; biliary: <5%.
