FLUDEOXYGLUCOSE F18 vs MIRALUMA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fludeoxyglucose F18 is a glucose analog that is taken up by cells via glucose transporters (GLUT), particularly GLUT-1. It is phosphorylated to FDG-6-phosphate by hexokinase, which cannot be further metabolized, leading to intracellular accumulation proportional to glucose metabolism. It emits positrons detected by PET 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).
5-10 mCi (185-370 MBq) intravenous injection, single dose for PET imaging.
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 is approximately 110 minutes (range 100–120 minutes). This reflects clearance of unmetabolized FDG from plasma and is clinically relevant for imaging timing, as optimal image acquisition occurs 30–60 minutes post-injection to allow for target-to-background ratio maximization.
20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Primarily renal; approximately 90% of injected activity is excreted unchanged in urine within the first 2 hours post-injection. Less than 5% is eliminated via feces.
90% renal as unchanged drug; 10% biliary/fecal
