E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To further evaluate safety, immunogenicity, and hemostatic efficacy of BAX 326 in those subjects who completed pivotal study 250901, until BAX 326 is licensed in the subjects country or until the total accumulation of at least 100 exposure days (EDs) of treatment with BAX 326, whichever occurs last To monitor incremental recovery of BAX 326 over time To evaluate changes in health-related quality of life (HR QoL) and health resource use |
- Evaluar mejor la seguridad, la inmunogenicidad y la eficacia hemostática de BAX 326 en los pacientes sometidos al estudio pivotal 250901 hasta que se autorice BAX 326 en el país de cada paciente o hasta completarse al menos 100 días de exposición (DE) a BAX 326, lo que ocurra más tarde. - Controlar la recuperación creciente de BAX 326 en el tiempo - Evaluar los cambios en la calidad de vida relacionada con la salud (CVRS) y la utilización de recursos sanitarios. |
