Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodine-131 is taken up by the thyroid gland and emits beta particles and gamma rays, causing destruction of thyroid tissue via radiation-induced cell death.
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).
For thyroid ablation: 3.7-5.55 MBq (100-150 μCi) orally as a single dose. For hyperthyroidism: 185-555 MBq (5-15 mCi) orally as a single dose.
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 half-life is approximately 120-140 days for total body iodine, but the effective half-life for therapeutic use is 8-13 days due to biological turnover in the thyroid. For diagnostic use, effective half-life is 1-2 days.
20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Primarily renal: >90% excreted in urine as iodide. Fecal excretion is negligible (<2%).
