Study Endpoints

Primary Endpoints

Maximum Plasma FVIII Activity (Cmax)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose
Area Under the Plasma FVIII Activity-Time Profile From Time 0 to Time of the Last Quantifiable Concentration (AUClast)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose
Area Under the Plasma FVIII Activity-Time Profile From Time 0 Extrapolated to Infinite Time (AUCinf)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose
Clearance (CL)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose

Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Volume of Distribution at Steady-State (Vss)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose

Volume of distribution is the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Vss is the volume of distribution at steady-state.

Terminal Phase Rate Constant (Kel)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose

Terminal phase rate constant is the absolute value of the slope of a linear regression during the terminal phase of the natural--logarithm transformed concentration--time profile.

Terminal Elimination Half-Life (t1/2)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose

Terminal half-life is the time measured for the plasma concentration to decrease by one half.

Mean Residence Time (MRT)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose

MRT = AUMCinf / AUCinf, where AUMCinf is the area under the first moment curve from zero time to infinity calculated as AUMCinf = AUMCt + ((t x Ct) / kel) + (Ct / kel\^2). AUMCt is the area under the first moment curve from zero time to time t calculated using the trapezoidal method.

Incremental Recovery (INCREC)
Pre-dose and 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32, 48, and 72 hours post-dose

Incremental recovery is the increase in circulating FVIII activity for every IU of Xyntha administered per kilogram of body weight.
