IOFLUPANE I-123 vs MIRALUMA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ioflupane I-123 is a radiopharmaceutical that binds with high affinity to the dopamine transporter (DAT) in the striatum. It allows visualization of presynaptic dopaminergic neurons via single-photon emission computed tomography (SPECT) imaging.
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).
Intravenous: 148-185 MBq (4-5 mCi) administered as a single IV bolus injection over 20-30 seconds, followed by saline flush.
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.

Terminal elimination half-life of ioflupane I-123 is approximately 25-30 hours. This prolonged half-life allows for imaging up to 6-8 hours post-injection with sustained target-to-background ratio, but requires consideration for radiation safety.
20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Primarily renal; about 60% of administered radioactivity excreted in urine within 24 hours, with 38% as unchanged ioflupane and 22% as metabolites. Fecal excretion accounts for approximately 14% over 48 hours. Additional elimination via biliary route is minimal.
90% renal as unchanged drug; 10% biliary/fecal
