MIRALUMA vs THALLOUS CHLORIDE TL 201
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).
Thallous chloride Tl-201 is a potassium analog that is taken up by viable myocardial cells via the Na+/K+ ATPase pump. Its distribution reflects regional myocardial blood flow and cell viability. In areas of ischemia or infarction, uptake is reduced, creating a perusion defect.
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.
111-148 MBq (3-4 mCi) intravenous injection for myocardial perfusion imaging; imaging begins 5-10 minutes post-injection.

20 hours; prolonged to 30-40 hours in renal impairment requiring dose adjustment
Terminal elimination half-life: approximately 73 hours. Clinical context: The long half-life allows for delayed imaging (e.g., redistribution imaging for thallium-201 myocardial perfusion scans).
90% renal as unchanged drug; 10% biliary/fecal
Renal: approximately 70% over 10 days; fecal: less than 30% over 10 days.
