To demonstrate the superiority of TMC435 versus placebo as part of a treatment regimen including peginterferon alfa-2a (PegIFNα-2a) and ribavirin (RBV), with respect to the proportion of subjects with sustained virologic response (SVR) 24 weeks after the planned end of treatment (SVR24). |

E.3 | Principal inclusion criteria |
1. Male or female subject aged 18 years or above.
2. Subject must have a liver biopsy within 3 years prior to the screening visit (or between the screening and baseline visit) with histology consistent with chronic HCV infection:
a. If only inflammation is present, there should be laboratory evidence of chronic hepatitis C infection, i.e., presence of anti-HCV antibody or HCV RNA for at least 6 months prior to Day 1;
b. If cirrhosis (Metavir score F4) has been demonstrated on a previous liver biopsy,
the 3-year time window does not apply and there is no need for a new biopsy.
c. A biopsy is not required for subjects with bleeding disorders.
3. Subjects with bridging fibrosis (Metavir score F3) or cirrhosis (Metavir score F4) must have an ultrasound taken within 6 months prior to the screening visit (or between the screening and baseline visit) with no findings suspicious for hepatocellular carcinoma.
4. Genotype 1 HCV infection (confirmed at screening).
5. Plasma HCV RNA of > 10,000 IU/mL at screening.
Note: retesting of HCV RNA to assess eligibility will be allowed once, using an unscheduled visit during the screening period.
6. Subjects must have received (Peg)IFN-based therapy for at least 24 weeks with documented undetectable HCV RNA at the last measurement on treatment, and a subsequent detectable HCV RNA level within 1 year after the last medication intake.
7. Female subjects of childbearing potential or male subjects with a female partner of
childbearing potential must agree to use 2 forms of effective contraceptive methods (one of the methods needs to be a barrier method, e.g., condom or diaphragm) from at least 2 weeks prior to Day 1 (baseline) until at least 6 months after the last dose of PegIFN alfa-2a/RBV (or longer if dictated by local regulations), or not be heterosexually active, or vasectomized (male subjects) or have a vasectomized partner (female subjects), or be a female (subject or partner of male subject) of nonchildbearing potential (i.e., postmenopausal for at least 2 years or surgically sterile) (for further details, refer to Section 4.4, Prohibitions and Restrictions).
8. Subjects must be willing and able to comply with the protocol requirements.
9. Subjects must have voluntarily signed an ICF indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.
Note: To participate in the optional pharmacogenomic component in this study (exploratory host genotyping), subjects must have voluntarily signed a separate ICF for this component. Refusal to give consent for this component does not exclude a subject from participation in the clinical study. |
|
E.4 | Principal exclusion criteria |
1. Evidence of hepatic decompensation (history or current evidence of ascites, bleeding varices or hepatic encephalopathy)
2. Any liver disease of non-HCV etiology. This includes acute hepatitis A, drug- or alcoholrelated liver disease, autoimmune hepatitis, hemochromatosis, Wilson's disease, alpha-1 antitrypsin deficiency, primary biliary cirrhosis, or any other non-HCV liver disease considered clinically significant by the investigator.
3. Infection/co-infection with nongenotype 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).
5. Co-infection with hepatitis B virus (hepatitis B surface antigen [HBsAg] positive).
6. Previous discontinuation of (Peg-)IFN or RBV for an adverse event that in the opinion of the investigator would likely be treatment limiting during re-exposure to PegIFNalfa-2a or RBV.
7. Known allergy or hypersensitivity to TMC435, PegIFNalfa-2a, RBV, or any of the other
components of the formulation.
8. Medical conditions which are contraindications for PegIFNalfa-2a or RBV therapy:
a. Major uncontrolled depressive illness;
b. Organ transplant (other than cornea or hair transplant or skin graft);
c. Severe concurrent medical disease such as severe hypertension, significant coronary heart disease, poorly controlled diabetes, untreated thyroid disease, chronic obstructive pulmonary disease, severe infections (bacterial, viral, fungal, including acute tuberculosis), or hemoglobinopathies (thalassemia major or sickle-cell anemia);
d. Autoimmune hepatitis or other autoimmune conditions known to be exacerbated by PegIFN and RBV. Any other clinically significant disease that in the opinion of the investigator would be exacerbated by the known effects of PegIFN and RBV.
10. History of malignancy within 5 years of the screening visit (exceptions: squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy that in the opinion of the investigator is considered cured with minimal risk of recurrence).
11. Subject with any of the following laboratory abnormalities:
a. Platelet count < 90,000/mm3;
b. Absolute neutrophil count < 1500 cells/mm3 (blacks: < 1200 cells/mm3);
c. Hemoglobin < 12 g/dL for women and < 13 g/dL for men;
d. Creatinine > 1.5 mg/dL;
e. ALT and/or AST > 10 x upper limit of laboratory normal range (ULN);
f. Total serum bilirubin > 1.5 x ULN;
g. Alpha-fetoprotein (AFP) > 50 ng/mL in subjects with cirrhosis (Metavir score F4).
Subjects without cirrhosis and AFP > 50 ng/mL must have an ultrasound between the
screening and baseline visit with no findings suspicious for hepatocellular carcinoma.
Note: retesting of abnormal laboratory values that lead to exclusion will be allowed once using an unscheduled visit during the screening period to assess eligibility.
12. Any other active clinically significant disease or clinically significant findings during
screening of medical history, physical examination, laboratory testing or ECG recording that, in the investigator?s opinion, would compromise the subject?s safety or could interfere with the subject participating in and completing the study.
Note: retesting of results that lead to exclusion will be allowed once using an unscheduled visit during the screening period to assess eligibility.
13. Current or past abuse of alcohol and/or recreational or narcotic drugs, which in the opinion of the investigator would compromise the subject?s safety and/or compliance with the study procedures.
14. Pregnant, planning on becoming pregnant, or breastfeeding female subject or male subject whose partner is pregnant or planning on becoming pregnant.
15. Subject who has received an investigational drug (including investigational vaccines) or used an invasive investigational medical device within 30 days of screening.
16. Use of disallowed concomitant therapy.
17. Previous treatment with any HCV therapy other than IFN and RBV, including any directacting anti-HCV agents (e.g., NS5B polymerase, NS3/4A protease or NS5A inhibitor, or cyclophilin inhibitors). |
