E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to demonstrate that in treatment-naïve chronic hepatitis C genotype 1 patients i) Fixed-duration triple therapy with DEB025 600 mg BID / 600 mg QD plus peg- IFNα2a/RBV for 48 weeks leads to a superior SVR24 rate as compared to peg- IFNα2a/RBV for 48 weeks AND/OR ii) Response-guided triple therapy with either 24 or 48 weeks with DEB025 400 mg BID plus peg-IFNα2a/RBV leads to a superior SVR24 rate as compared to peg-IFNα2a/RBV for 48 weeks AND/OR iii) Response-guided triple therapy with either 24 or 48 weeks with DEB025 600 mg BID / 600 mg QD plus peg-IFNα2a/RBV leads to a superior SVR24 rate as compared to peg- IFNα2a/RBV for 48 weeks. |
Obiettivo primario: dimostrare nei pazienti con epatite cronica C genotipo 1 naive che: i) la triplice terapia con DEB025 600 mg QD in associazione a PEG-IFN-α2a e RBV per una durata di trattamento prestabilita di 48 settimane (comprensive della loading dose*) permetta di ottenere un tasso di SVR24 superiore rispetto al trattamento con PEG-IFN-α2a e RBV per 48 settimane; E/O ii) la triplice terapia per un periodo di tempo sia di 24 che di 48 settimane, in base alla risposta al trattamento (response-guided therapy), con DEB025 400 mg BID in associazione a PEG-IFN-α2a e RBV permetta di ottenere un tasso di SVR24 superiore rispetto al trattamento con PEG-IFN-α2a e RBV per 48 settimane E/O Per favore ved. sinossi in italiano |

E.2.2 | Secondary objectives of the trial |
The key secondary objectives include evaluating whether response-guided triple therapy with DEB025 600 mg BID / 600 mg QD plus peg-IFNα2a/RBV or DEB025 400 mg BID plus peg- IFNα2a/RBV has similar efficacy as the fixed duration triple therapy in terms of proportion of patients achieving SVR24. These analyses will be conducted at a descriptive level. 2.3 Other Secondary objectives • To evaluate the proportions of patients who achieve the following virologic response in each treatment arm: • RVR4LOQ: “Rapid Virologic Response by LOQ”: serum HCV RNA < LOQ (limit of quantification) after 4 weeks of treatment • RVR4LOD: “Rapid Virologic Response by LOD”: serum HCV RNA < LOD (limit of detection) after 4 weeks of treatment • EVR: “Early Virologic Response”: HCV RNA decrease ≥ 2 log10 or HCV RNA < LOQ (limit of quantification) after 12 weeks of treatment • PLEASE SEE PROTOCOL |
Obiettivo secondario principale: esplorare se con un periodo di trattamento più corto (24 settimane) guidato dalla risposta al trattamento in corso di trattamento (response-guide therapy) si possa ottenere un tasso di SVR24 simile a quello ottenuto con la triplice terapia (DEB025 in associazione a PEG-IFN-α2a + RBV) per 48 settimane Per maggiori dettagli consultare il capitolo 3 del protocollo originale. |

In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment 3.

Only 4 weeks after permanent discontinuation of DEB02/placebo: Use of oral, injected or implanted hormonal methods of contraception. Women are considered not to be of child bearing potential (thus eligible without contraception) if they: • are post menopausal as defined as at least 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms), or PLEASE SEE PROTOCOL |
