Pharmacokinetic Characterization of the Hemophilia A Population in Spain Using myPKFiT®

Completed
Conditions
Hemophilia A
Factor VIII Deficiency
Hemophilia
Interventions
Registration Number
NCT03006965
Lead Sponsor
Spanish Society of Thrombosis and Haemostasis
Brief Summary

The purpose of this study is to describe the pharmacokinetic profile of patients with hemophilia A in prophylaxis in Spain using myPKFit®

Detailed Description

This pharmacokinetic profile will be obtained in only in patient using Advate® (INN-octocog alfa) or Adynovi® (INN- rurioctocog alfa pegol), both recombinant intravenous FVIII products, with myPKFiT®. This patients will be followed during the period of 12 months, and the pharmacokinetic will be measured collecting at least 2 blood samples, in which the presence of factor VIII will be determined by the usual clinical methods: chromogenic method or coagulative method.

Hemophilia A patientsoctocog alfaGroup of patients in prophylactic treatment with Advate® (octocog alfa) or Adynovi® (rurioctocog alfa pegol), or patients using already myPKFit®. Patients will be given a dose of octocog alfa or rurioctocog alfa pegol according to usual clinical practice, and two blood samples will be taken in case of octocog alfa: one sample will be extracted 3-4h postdose (+/- 30 minutes), and the second sample will be extracted 24-32h postdose (+/- 60 minutes). In case of rurioctocog alfa pegol, the first sample is taken in the same conditions than octocog alfa, and the second sample will be extracted 48h postdose (+/- 120 minutes), and other sample post 72h(+/- 120 minutes) optional.
