E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectives of this study are to assess the efficacy (the percentage of subjects achieving SVR12, HCV RNA < lower limit of quantification [LLOQ] 12 weeks following treatment) and safety of ABT- 450/r/ABT-267, and ABT-333 co-administered with RBV for 12 weeks in pegIFN/RBV treatment-experienced HCV genotype 1-infected adults. |
Gli obiettivi primari di questa sperimentazione sono rappresentati dalla valutazione dell'efficacia (percentuale di soggetti che ottengono una risposta virologica sostenuta della durata di 12 settimane, SVR12 (HCV acido ribonucleico (RNA) < limite inferiore di quantificazione [LLOQ] 12 settimane dopo il trattamento) e della sicurezza di ABT-450/r/ABT-267 e ABT-333 in co-somministrazione con RBV per 12 settimane in adulti con infezione da HCV di genotipo 1 precedentemente trattati con pegIFN/RBV. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are to assess the percentage of subjects with ALT normalization, the percentage of subjects with virologic failure during treatment, and the percentage of subjects with relapse post-treatment. |
Gli obiettivi secondari di questa sperimentazione sono la valutazione della percentuale di soggetti con normalizzazione dei livelli di ALT, della percentuale di soggetti con fallimento virologico durante il trattamento e della percentuale dei soggetti con recidiva dopo il trattamento. |

|
E.4 | Principal exclusion criteria |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the percentage of subjects with SVR12. |
L’endpoint primario di efficacia è rappresentato dalla percentuale di soggetti con SVR12. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 weeks after last dose of study drug. |
12 Settimane dopo l’ultima dose di farmaco sperimentale. |
|
E.5.2 | Secondary end point(s) |
1. The percentage of subjects in either treatment group with ALT normalization at the end of treatment (defined as ALT ≤ ULN at Final DB Treatment Visit for subjects with ALT > ULN at Baseline); 2. The percentage of subjects in the active treatment group with virologic failure during treatment (defined as confirmed HCV RNA ≥ LLOQ after HCV RNA < LLOQ during treatment or HCV RNA ≥ LLOQ at the end of treatment); 3. The percentage of subjects in the active treatment group with posttreatment relapse (defined as HCV RNA ≥ LLOQ between end of treatment and 12 weeks after the last dose of study drugs among subjects completing treatment and with HCV RNA < LLOQ at the end of treatment). |
1) Percentuale di soggetti con normalizzazione dei livelli di ALT alla fine del trattamento in entrambi i gruppi di trattamento (definita come ALT ≤ ULN alla Visita Finale di Trattamento nell'ambito del Periodo di Trattamento DB per i soggetti con ALT > ULN al Baseline); 2) Percentuale di soggetti nel braccio di trattamento attivo con fallimento virologico durante il trattamento (definito come confermato HCV RNA ≥ LLOQ dopo HCV RNA < LLOQ durante il trattamento o HCV RNA ≥ LLOQ alla fine del trattamento); 3) Percentuale di soggetti nel gruppo di trattamento attivo con recidiva dopo il trattamento (definito come HCV RNA ≥ LLOQ tra la fine del trattamento e 12 Settimane dopo l’ultima dose di farmaco sperimentale fra i soggetti che stanno completando il trattamento e con HCV RNA < LLOQ alla fine del trattamento). |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
