MIRALUMA vs MPI DMSA KIDNEY REAGENT
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).
DMSA (dimercaptosuccinic acid) labeled with technetium-99m binds to renal cortex, particularly proximal tubular cells, allowing scintigraphic imaging of functional renal parenchyma. Uptake correlates with renal blood flow and tubular function.
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.
Adults: 74-185 MBq (2-5 mCi) intravenously, single dose for renal imaging.

20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Initial whole-body half-life of dimer captosuccinic acid (DMSA) is 1.1 hours; terminal elimination half-life for cortical retention is 56 days, reflecting prolonged renal tubular uptake.
90% renal as unchanged drug; 10% biliary/fecal
Renal: ~50% excreted unchanged in urine within 24 hours; remaining fraction retained in renal tubular cells with gradual release over weeks.
