General information about the trial
|
|||
Main objective of the trial |
To assess immunogenicity of Octanate® in PUPs by monitoring the levels of inhibitor against FVIII (Bethesda assay) every 3-4 exposure days until the 20th exposure day and every 10th exposure day until exposure day 100 or every 3 months, whichever comes first.
|
||
Protection of trial subjects |
This trial was conducted in accordance to the principles of GCP, ensuring that the rights, safety and well-being of patients are protected and in consistency with the Declaration of Helsinki. Inclusion and exclusion criteria were carefully defined in order to protect subjects from contraindications, interactions with other medication and risk factors associated with the investigational medicinal product. Safety was assessed throughout the study, such as occurrence of AEs, testing of virology and testing of immunogenicity .
