Biological Activity

Osocimab (BAY 1213790), an anti-FXIa antibody (Ki=2.4 nM; EC50=0.2 nM). FXI inhibition may reduce the risk of thrombosis. Osocimab inhibits thrombin generation, and prolongs activated partial thromboplastin time. Osocimab exhibits anticoagulant effects.

Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
