E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare systemic VEGF-A levels following monthly intravitreal injections of 0.5 mg ranibizumab (treatment group 1) versus monthly 2mg aflibercept (treatment group 3) as measured by the area under the curve (AUC) from baseline to study week 24 |
Per confrontare i livelli di VEGF-A sistemico dopo iniezioni intravitreali mensili di ranibizumab 0,5 mg (gruppo di trattamento 1) rispetto ad aflibercept 2 mg mensile (gruppo di trattamento 3) misurati come l'area sotto la curva (AUC) dal basale alla settimana 24. |
|
E.2.2 | Secondary objectives of the trial |
To compare systemic VEGF-A levels in patients switching from monthly 2 mg aflibercept injections for first three months to monthly 0.5 mg ranibizumab (treatment group 2) for the next three months compared to patients treated with monthly 0.5 mg ranibizumab (treatment group 1) for six months at specific time points from week 12 to week 24. To compare systemic VEGF-A levels in patients switching from monthly 2 mg aflibercept injections for first three months to monthly 0.5 mg ranibizumab (treatment group 2) for the next three months compared to patients treated with monthly 2 mg aflibercept (treatment group 3) for six months at specific time points from week 12 to week 24.

Confrontare i livelli di VEGF-A sistemico in pazienti che passano da iniezioni mensili di aflibercept 2 mg a ranibizumab 0,5 mg mensile (gruppo di trattamento 2) per i successivi tre mesi, rispetto ai pazienti trattati con ranibizumab 0,5 mg mensile (gruppo di trattamento 1) per sei mesi in momenti specifici dalla settimana 12 alla settimana 24. Confrontare i livelli di VEGF-A sistemico in pazienti che passano dalle iniezioni mensili di aflibercept 2 mg per i primi tre mesi di tempo a ranibizumab 0,5 mg mensile (gruppo di trattamento 2) per i successivi tre mesi, rispetto ai pazienti trattati con aflibercept 2 mg mensile (gruppo di trattamento 3) per sei mesi in momenti specifici dalla settimana 12 alla settimana 24. - Valutare la sicurezza oculare e sistemica in tutti e tre i gruppi di trattamento. |
