E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to evaluate the efficacy of 6 different regimens of TMC435 in combination with PegIFNα-2a and RBV (i.e., SoC), defined as the proportion of subjects with undetectable HCV RNA (< 10 IU/mL) 24 weeks after the planned end of treatment (SVR24), compared to the control group receiving SoC in combination with TMC435-matched placebo. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are: - To evaluate and compare the antiviral activity of TMC435 when administered in different regimens versus control (SoC) over the trial period; - To evaluate and compare the antiviral activity of TMC435 when administered in different regimens versus control (SoC) over the trial period in the different subpopulations (prior null responders/partial responders/relapsers); - To evaluate and compare the safety and tolerability of the TMC435-containing regimens versus SoC over the trial period; - To determine the frequency/kinetics and viral genetics of virologic failures; - To evaluate the pharmacokinetics and the pharmacokinetic/pharmacodynamic relationship for efficacy and safety of TMC435; - To collect Medical Resource Utilization information, and to evaluate Quality of Life (QoL) and the level of fatigue over the trial period. |

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Title: A substudy of TMC435-TiDP16-C206 to evaluate the pharmacokinetic profile of TMC435 as part of a treatment regimen including peginterferon alpha (PegIFNα)-2a and ribavirin (RBV) in hepatitis C virus genotype 1 infected subjects who failed to respond or relapsed following at least 1 course of PegIFNα-2a/b and RBV therapy.
Date: 24 July 2009
Version: Final
Objectives: The objective of this substudy is to obtain steady-state pharmacokinetic profiles of MC435 in plasma, at a timepoint between at least 4 weeks and up to 6 weeks of TMC435 100 or 150 mg q.d. treatment in combination with SoC consisting of PegIFNα-2a and RBV. |

E.3 | Principal inclusion criteria |
Subjects who meet all of the following criteria are eligible for this trial: 1. Male or female subject aged between 18 and 70 years, extremes included; 2. Documented chronic hepatitis C infection as evidenced by all of the following: - a liver biopsy demonstrating chronic viral hepatitis within 2 years of screening; - anti-HCV positive; - HCV RNA positive (if only inflammation is present on liver biopsy, HCV RNA presence should be documented for at least 6 months prior to baseline). Note: If no biopsy is available, one will be performed on a separate day during screening. For subjects with cirrhosis diagnosed by prior biopsy (evidence of which should be available in the source documents) and no evidence of hepatocellular carcinoma (confirmed by alpha-fetoprotein [AFP] level < 50 ng/mL and ultrasound at screening), another biopsy is not required. 3. Genotype 1 HCV infection (confirmed at screening); 4. Plasma HCV RNA of > 10,000 IU/mL at screening (as assessed by standard quantitative in vitro nucleic acid amplification assay); Note: Retesting of HCV RNA to reassess eligibility will be allowed only once using an unscheduled visit during the screening period. 5. At least 1 prior documented course of PegIFNα-2a/RBV or PegIFNα-2b/RBV therapy for at least 12 consecutive weeks which has not been discontinued due to intolerability to PegIFNα-2a/b and RBV therapy; Note: Subjects who were treated with (Peg)IFN monotherapy are not allowed. 6. Body weight between 40 and 125 kg; 7. Subject (male with partner of childbearing potential or female of childbearing potential) agrees to use 2 separate forms of highly effective contraception methods (1 of the methods needs to be a barrier method, e.g., condom or diaphragm) from screening throughout the duration of study treatment and for 7 months after the last dose of RBV, or is non-heterosexually active, vasectomized (male subject) or has a vasectomized partner (female subject), or is a female (subject or partner of male subject) of non-childbearing potential; 8. Informed consent signed voluntarily before the first trial-related activity; 9. Being able to comply with the protocol requirements. |
|
E.4 | Principal exclusion criteria |
Subjects meeting 1 or more of the following criteria cannot be selected: 1. Decompensated liver disease defined as history or presence of ascites, hepatic encephalopathy, esophageal bleeding, or gastric varices. 2. Any other liver disease of non-HCV etiology; this may include but is not limited to hepatitis A or B, drug- or alcohol-related liver disease, autoimmune hepatitis, hemochromatosis, Wilson’s disease, non-alcoholic steatohepatitis (NASH) or primary biliary cirrhosis; 3. Infection/co-infection with non-genotype 1 HCV; 4. Co-infection with HIV type 1 or type 2 (HIV-1 or HIV-2) (positive HIV-1 or HIV-2 antibodies test at screening) or hepatitis B virus infection (hepatitis B surface antigen [HbsAg]); 5. History of invasive malignancy diagnosed or treated within 5 years prior to screening (locally treated non-invasive basal cell skin carcinoma is permitted; cervical carcinoma in situ is allowed if treated prior to screening); 6. Evidence of hepatocellular carcinoma (e.g., AFP > 50 ng/mL); 7. Medical conditions that are exclusion criteria for PegIFNα-2a or RBV treatment (please refer to the manufacturer’s prescribing information for details): − Presence or history of psychiatric disorders including but not limited to severe depression, anxiety disorders, psychotic disorders, a history of hospitalization for any psychiatric disorder or a suicide attempt; − Uncontrolled/unstable cardiac disorders (e.g., congestive heart failure, supraventricular arrhythmias); − Uncontrolled/unstable chronic pulmonary disorders (e.g., chronic obstructive pulmonary disease); − Severe bacterial, viral or fungal infections including acute tuberculosis; − Uncontrolled/unstable thyroid disease (hypo- or hyperthyroidism); − Uncontrolled/unstable diabetes mellitus (e.g., glycated hemoglobin [HbA1c] ≥ 7%, diabetic retinopathy); − Renal impairment (e.g., serum creatinine >1.5 x ULN or creatinine clearance < 50 mL/min); − Anti-nuclear Antibody (ANA) titer ≥ 1:320; − Autoimmune disease (e.g., Graves’ disease); − Hemoglobinopathies (e.g., thalassemia major or sickle-cell anemia). 8.

Having any of the following laboratory abnormalities: − AST and/or ALT > 10 x ULN; − Laboratory evidence of significantly decreased hepatic function or decompensation (i.e., international normalized ratio [INR] > 1.5, or albumin < 30 g/L, or bilirubin > 1.5 x upper limit of laboratory normal range [ULN]); − Laboratory abnormalities that are exclusion criteria for PegIFNα-2a or RBV treatment (please refer to the manufacturer’s prescribing information for details): a.
