E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the haemostatic effect of N8-GP during surgical procedures
in patients with
haemophilia A |
Valutare l’effetto emostatico di N8-GP nel corso delle operazioni chirurgiche in pazienti affetti da emofilia A |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the general safety including immunogenicity of N8-GP
when used for prevention and treatment of bleeding throughout the
surgical period
- To evaluate the haemostatic effect of N8-GP during the post-operative
period
- To evaluate health economic resource use (hospitalisation days) due to
surgery |
-Valutare la sicurezza generale,inclusa l’immunogenicità,di N8-GP usato nella prevenzione e il trattamento dei sanguinamenti nel corso dell’intero periodo chirurgico
-Valutare l’effetto emostatico di N8-GP durante il periodo post-operatorio
-Valutare l’uso delle risorse di economia sanitaria (HE) (giorni di ricovero) correlate all’intervento chirurgico |
