E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectives of this study are to assess safety and efficacy (the percentage of subjects achieving a 12-week sustained virologic response, SVR12 (HCV ribonucleic acid [RNA] < lower limit of quantification [LLOQ] 12 weeks following treatment) of coformulated ABT-450/r and ABT-267 (ABT-450/r/ABT-267) and ABT-333 coadministered with RBV for 24 weeks in HCV genotype 1-infected adult liver transplant recipients. |
Los objetivos principales de este estudio consisten en evaluar la seguridad y la eficacia (porcentaje de sujetos que logren una respuesta virológica mantenida a las 12 semanas, RVM12 (ácido ribonucleico (ARN) del VHC < límite inferior de cuantificación (LIC), 12 semanas después del tratamiento) de ABT-450 en formulación conjunta con ritonavir (r) y ABT-267 (ABT-450/r/ABT-267) y ABT-333 administrado conjuntamente con ribavirina (RBV) durante 24 semanas en receptores adultos de un trasplante hepático con infección recurrente por el VHC de genotipo 1. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are to assess the percentage of subjects achieving a 24-week sustained virologic response, SVR24 (HCV RNA < LLOQ 24 weeks following treatment), the percentage of subjects with virologic failure during treatment, and the percentage of subjects with relapse post-treatment. |
Los objetivos secundarios de este estudio consisten en evaluar el porcentaje de sujetos con fracaso virológico durante el tratamiento, el porcentaje de sujetos que logren una respuesta virológica mantenida a las 24 semanas, RVM24 (ARN del VHC < LIC, 24 semanas después del tratamiento) y el porcentaje de sujetos con recidiva después del tratamiento. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female between the ages of 18 and 70 years, inclusive, at time of enrollment. 2. Liver transplantation as a consequence of HCV infection no less than 12 months before the Screening Visit. 3. A liver biopsy which shows evidence of fibrosis ? F2 (Metavir scale) within 3 months prior to or during the Screening Period. 4. Screening laboratory result indicating HCV genotype 1 infection. 5. Currently taking an immunosuppressant regimen based on either tacrolimus or cyclosporine where doses of immunosuppressant drugs have not been increased over the 3 months prior to Screening and no new drugs have been added for at least 3 months before Screening. Corticosteroids such as prednisone or prednisolone are permitted as components of the immunosuppressant regimen providing the dose is not more than 5 mg/day. |
1. Varones o mujeres con una edad comprendida entre los 18 y 70 años, ambos inclusive, en el momento de inclusión. 2. Trasplante hepático como consecuencia de la infección por el VHC no menos de 12 meses antes de la visita de selección. 3. Biopsia hepática que revele datos de fibrosis ? F2 (escala de puntuación Metavir) en los 3 meses previos al período de selección o durante el mismo. 4. Resultado analítico en la selección indicativo de una infección por el VHC de genotipo 1. 5. Tratamiento presente con un régimen inmunosupresor a base de tacrolimus o ciclosporina en el que no se han aumentado las dosis de inmunosupresores durante los 3 meses previos a la selección y no se han añadido fármacos nuevos durante, al menos, 3 meses antes de la selección. Se permite el uso de corticosteroides, como prednisona o prednisolona, como componentes del régimen inmunosupresor, siempre que la dosis no sea superior a 5 mg/día. |
|
E.4 | Principal exclusion criteria |
- Positive test result for Hepatitis B surface antigen (HBsAg) or anti-Human Immunodeficiency virus antibody (HIV Ab). - Clinically significant abnormalities, other than HCV infection in a subject post transplant, based upon the results of a medical history, physical examination, vital signs, laboratory profile and a 12-lead electrocardiogram (ECG) that make the subject an unsuitable candidate for this study in the opinion of the investigator. - Recent (within 6 months prior to study drugs administration) history of drug or alcohol abuse that, in the opinion of the investigator, could preclude adherence to the protocol. - Previous use of any investigational or commercially available anti-HCV agent other than IFN-based therapy, i.e. conventional (c)IFN and/or pegylated (Peg) IFN, with or without RBV, including previous exposure to ABT-450, ABT-333 or ABT-267. |
- Resultado positivo en el análisis del antígeno de superficie del virus de la hepatitis B (HbsAg) o de anticuerpos contra el virus de la inmunodeficiencia humana (Ac anti-VIH). - Anomalías clínicamente importantes, aparte de la infección por el VHC, después del trasplante, basadas en los resultados de la anamnesis, la exploración física, las constantes vitales, las pruebas analíticas y un electrocardiograma (ECG) de 12 derivaciones que hacen que, en opinión del investigador, el sujeto no sea un candidato adecuado para este estudio. - Antecedentes recientes (en los 6 meses previos a la administración de los fármacos del estudio) de alcoholismo o toxicomanía que, en opinión del investigador, podrían impedir el cumplimiento del protocolo. - Uso previo de cualquier fármaco en investigación o comercializado contra el VHC distinto de un tratamiento a base de interferón (IFN), es decir, IFN convencional (IFNc) o pegilado (IFNpeg), con o sin RBV, incluida la exposición previa a ABT-450, ABT-333 o ABT-267. |
