E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of the study is to assess the therapeutic equivalence of two different formulation of Travoprost PR (Travoprost PR versus Travatan) in the treatment of subjects affected by primary angle glaucoma (POAG) or ocular hypertension (OH) treated for 12 weeks.
Primary end-point will be the change in IOP from baseline in 2 study groups at 12 weeks. |
obiettivo principale dello studio la valutazione dell’equivalenza terapeutica di due colliri contenenti Travoprost (Travoprost PR versus Travatan) nel trattamento, per 12 settimane, di soggetti affetti da glaucoma primario ad angolo aperto o da ipertensione oculare.
L’obiettivo primario è la dimostrazione dell’equivalenza terapeutica dei due prodotti in termini di cambiamento della pressione oculare (IOP) al termine delle 12 settimane di trattamento in confronto ai valori basali. |
|
E.2.2 | Secondary objectives of the trial |
Secondary end-points will be:
•To assess local tolerability of the two formulations, in terms of local adverse events,
•To assess systemic tolerability of the two formulations in terms of changes in vital parameters (arterial blood pressure and heart rate will be registered at each visit), onset of systemic adverse events (registered at each visit) and changes in laboratory parameters (assessed at the entry and at the end of the 12-week treatment),
•To calculate the percentage change in IOP from start to end of 12-week treatment,
•To calculate the reduction in IOP by both formulation, at each time point at baseline and at the end of the 12-week treatment. |
Gli obiettivi secondari sono:
•La valutazione della tollerabilità locale dei due prodotti, in termini di eventi avversi locali,
•La valutazione della tollerabilità sistemica dei due prodotti in termini di cambiamento dei parametri vitali (pressione arteriosa e frequenza cardiaca rilevate ad ogni visita), insorgenza di eventi avversi sistemici (registrati ad ogni visita) e variazione dei parametri di laboratorio (valutazioni effettuate alla visita di screening e a quella finale),
•Il calcolo della variazione percentuale della pressione oculare al termine dello studio rispetto ai valori di base,
•Il calcolo della riduzione della pressione oculare nelle diverse ore di misurazione della IOP. |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary outcome will be the change in IOP from baseline in 2 study groups at 12 weeks. |
Il parametro principale di efficacia è la differenza in termini di riduzione della pressione oculare tra i valori osservati al basale rispetto a quelli registrati al termine dello studio (12 settimane) nei due bracci di trattamento. |
