What is being measured
The primary outcome is the main question the study is designed to answer.
Safety (Physical Examination, Vital Signs, ECG, Haematology, Biochemistry, Urinalysis, Coagulation Factors, Coagulation-related Parameters, Injection Site Tolerability and Adverse Events (AE))
Any safety issue was reported as AE
Measured: between dosing and 2-3 weeks after dosing
Subjects With Anti-Vatreptacog Alfa Antibody
Post-dosing samples from subjects were evaluated for the presence of Anti-Vatreptacog alfa antibody
Measured: between dosing, 2-3 weeks after dosing, and 11-13 weeks after dosing
Secondary outcomes (12)
Vatreptacog Alfa Clot Activity: Area Under the FVIIa Activity-time Curve From Time 0 and up Until the Last Quantifiable Activity (AUC0-t)
AUC0-t was computed using the linear trapezoid rule. Plasma FVIIa clot activity at time 0 was calculated by log linear interpolation.
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity: Area Under the FVIIa Activity-time Curve From Time 0 to 24 h (AUC0-24)
Blood samples were collected at following time points: -30 min, -20 min, -10 min, 5 min, 10 min, 20 min, 30 min, 1 h, 2h, 3h, 4h, 5h, 8h, 12h and 24h to calculate area under the curve.
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity: Area Under the FVIIa Activity-time Curve From Time 0 h to Infinity (AUC 0-inf)
AUC0-inf = AUC0-t + (Ct / λz), Where Ct is the last quantifiable activity and t the time of Ct.
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity: Maximum FVIIa Activity (Cmax)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity: FVIIa Activity Measured 5 Min After Administration of NN1731 (C5min)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity: Back Extrapolated Estimate of the Initial FVIIa Activity (C0)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity- Terminal Slope (λz)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity: Terminal Half-life (t1/2)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity- Total Clearance (CL)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity- Apparent Volume of Distribution at Steady State (Vss)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity- Initial Volume of Distribution (VD)
Measured: during 1-2 days after drug administration
Vatreptacog Alfa Clot Activity- Mean Residence Time (MRT)
Mean residence time of the unchanged drug in the systemic circulation
Measured: during 1-2 days after drug administration
