GALLIUM CITRATE GA 67 vs MIRALUMA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gallium citrate Ga 67 is a radiopharmaceutical that localizes in tumors and inflammatory lesions. The mechanism is not fully understood but may involve binding to transferrin and uptake via transferrin receptors, as well as accumulation in lysosomes of macrophages and tumor cells.
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).
2-5 mCi (74-185 MBq) intravenously once; repeat imaging may require an additional 2-5 mCi at 48-72 hours.
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: approximately 25 days (range 6-72 days) in soft tissues; reflects slow clearance from binding sites (e.g., transferrin, lactoferrin).
20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Renal: approximately 25% within first 24 hours; fecal: approximately 10% within 48 hours; retained in tissues (bone, liver, spleen) with slow release over weeks.
90% renal as unchanged drug; 10% biliary/fecal
