Parameter | Unit | Estimate | %RSE |
CLL | mL/h/kg | 0.14 | 6.1 |
V1 | mL/kg | 33 | 34 |
V2 | mL/kg | 33 | - |
Q | mL/h/kg | 0.12 | 16 |
F | % | 93 | 7.7 |

CL
L: the linear part of the clearance.
V1: the volume of the central compartment.
V2: the volume of the peripheral compartment.
V
max: the maximum amount of anti-TFPI cleared per time unit via binding to TFPI.
K
m: the concentration at which the target mediated elimination rate is 50% of the maximum value (Vmax).
T
1/2(abs): the absorption half-life, describing the rate of absorption after sc administration.
%RSE: residual standard error.
Animal Model: | Cynomolgus monkeys (target mediated drug disposition (TMDD) model)[2]. |
Dosage: | 20mg/kg or 200 mg/kg |
Administration: | Intravenous injection/subcutaneous injection |
Result: | Showed a high bioavailability (93%) and the absorption half-life is estimated to be 72 h.
