Population pharmacokinetics tools and uses thereof
First Claim
1. A method of treating hemophilia in a subject in need thereof comprising(i) calculating a therapeutic dose of a chimeric clotting factor and/or a dosing interval of the chimeric clotting factor for the subject using a web-based application that is accessible through a web server, wherein the application is programmed to implement a clotting factor population pharmacokinetic (popPK) model for said chimeric clotting factor and a Bayesian estimation program to calculate the therapeutic dose and/or dosing interval;
- and,(ii) administering the chimeric clotting factor at the calculated therapeutic dose and/or the dosing interval to the subject wherein(a) the chimeric clotting factor comprises a FVIII polypeptide and a neonatal Fc receptor binding partner (FcRn BP), and the clotting factor popK model for the chimeric clotting factor comprises the parameters in Table 18, 24 or 25;
or(b) the chimeric clotting factor comprises a FIX polypeptide and an FcRn BP, and the clotting factor popK model for the chimeric clotting factor comprises the parameters in Table 10, 13 or 14.
