MIRALUMA vs PLUVICTO
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).
Lutetium Lu 177 vipivotide tetraxetan is a radioligand therapeutic agent that binds to prostate-specific membrane antigen (PSMA), which is overexpressed on prostate cancer cells. After binding, the radioactive isotope lutetium-177 emits beta particles, causing DNA damage and cell death.
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.
PLUVICTO (lutetium Lu 177 vipivotide tetraxetan) is administered intravenously at a dose of 7.4 GBq (200 mCi) every 6 weeks for up to 6 doses, in combination with a gonadotropin-releasing hormone (GnRH) analog or after prior unilateral orchiectomy.

20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Effective half-life of lutetium-177 is approximately 160 hours (6.67 days), reflecting both physical decay (T1/2 6.647 days) and biological clearance. Clinical context: Due to physical decay, therapeutic radioactivity decreases to <1% after about 45 days.
90% renal as unchanged drug; 10% biliary/fecal
Primarily renal; approximately 60% of administered radioactivity excreted in urine within 24 hours, with gradual elimination thereafter. Biliary/fecal excretion accounts for <15%.
