E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the effect of response to treatment (assessed by SVR12 status) on the long-term progression of liver disease in adults with chronic HCV GT1 infection who received treatment with ABT-450/r/ABT-267 and ABT-333 with or without ribavirin, as measured by all-cause death, liver-related death, liver decompensation, liver transplantation, and hepatocellular carcinoma.
|
L’obiettivo primario di questo studio è valutare gli effetti della risposta al trattamento (definita in base alla risposta virologica sostenuta [sustained virological response, SVR12]) sulla progressione a lungo termine dell’epatopatia negli adulti con infezione cronica da HCV GT1 già sottoposti a trattamento con ABT-450/r/ABT-267 e ABT-333 con o senza ribavirina, in base all’incidenza di decessi per tutte le cause o correlati al fegato, decompensazione epatica, trapianti di fegato e carcinomi epatocellulari. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the long-term progression of fibrosis by baseline fibrosis stage and sustained virologic response, as measured by change from baseline in liver stiffness measured by transient elastography (FibroScan®) when available, in adults with genotype 1 (GT1) chronic HCV infection who received treatment with ABT-450/r/ABT-267 and ABT-333 with or without ribavirin.
To evaluate the percentage of subjects achieving SVR12 with ABT-450/r/ABT-267 and
ABT-333 with or without ribavirin in adults with GT1 chronic HCV infection |
Valutare la progressione a lungo termine della fibrosi in base allo stadio della patologia al basale e alla risposta virologica sostenuta, alla luce delle variazioni rispetto al basale del grado di rigidità del fegato, misurate tramite elastografia a impulsi (FibroScan®) laddove disponibile, negli adulti con infezione cronica da HCV di genotipo 1 (GT1) precedentemente trattati con ABT-450/r/ABT-267 e ABT-333 con o senza ribavirina. Valutare la percentuale di soggetti che raggiungono la SVR12 in seguito al trattamento con ABT-450/r/ABT-267 e ABT-333 con o senza ribavirina negli adulti con infezione cronica da HCV GT1. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the incidence of all-cause death, liver-related death, liver decompensation, liver transplantation, hepatocellular carcinoma, and the composite of any of the above outcomes observed during the post-treatment period. |
L’endpoint primario è l’incidenza di decessi per tutte le cause o correlati al fegato, decompensazione epatica, trapianti di fegato, carcinomi epatocellulari e la combinazione di qualsiasi degli esiti sopra indicati osservata durante il periodo di post-trattamento. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 weeks after last dose of study drugs |
12 settimane dopo l’ultima dose dei farmaci in studio |
|
E.5.2 | Secondary end point(s) |
1. The effect of sustained virologic response and baseline fibrosis stage on longitudinal change from baseline in Fibroscan score (assessed at the end of treatment and/or post-treatment visits) will be evaluated by comparing mean change between subjects who achieve SVR12 and those who do not. Point estimates and 95% confidence intervals will be provided.
2. The percentage of subjects achieving SVR12 (HCV RNA < LLOQ 12 weeks after the last actual dose of study drug). The simple percentage of subjects achieving SVR12 will be calculated and a two-sided 95% confidence interval of the percentage will be computed based on Wilson's score method.
|
1. Saranno valutati l’effetto della risposta virologica sostenuta e lo stadio della fibrosi al basale con variazione longitudinale con il punteggio Fibroscan (valutazione alle visite di fine trattamento e/o post-trattamento) facendo un confronto tra i soggetti che ottengono SVR12 e quelli che non raggiungono questo obiettivo. Saranno forniti gli intervalli di confidenza (IC) al 95% e le stime dei punti. 2. La percentuale dei soggetti che ottengono SVR12 (HCV RNA < LLOQ 12 settimane dopo l’ultima effettiva dose del farmaco in studio). Sarà calcolata la semplice percentuale di soggetti che ottengono SVR12 e l’intervallo di confidenza bilaterale al 95% della percentuale sarà determinato sulla base del punteggio di Wilson. |
