E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy of SCH 503034 800 mg TID PO in combination with PegIntron 1.5 µg/kg QW SC plus ribavirin (800-1400 mg QD PO) in previously untreated adult CHC subjects infected with Genotype 1. |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate the safety of SCH 503034 when used in combination with PegIntron 1.5 µg/kg QW SC plus ribavirin (800-1400 mg QD PO). 2. To assess the relationship of a) early virologic response (EVR) and b) time to HCV-RNA negative, to sustained virologic response (SVR). 3. To assess the effect of the 4 week lead in with PegIntron and ribavirin on SVR (FW 24). 4.To assess the effect of duration of treatment with SCH 503034 on SVR. 5. To assess the proportion of subjects with HCV-RNA levels below the limit of detection at FW 12. 6. To assess the proportion of subjects with HCV-RNA levels below the limit of detection at 72 weeks post randomization. 7. To explore the relationship between virologic response at FW 12, FW 24 (SVR), and 72 weeks post randomization.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Subject must be between 18 and 60 years of age; 2. Subject’s body weight must be between 45 and 125 kg; 3. Subject must have documented chronic hepatitis C genotype 1 with most recent (within 6 months of Day 1) quantitative HCV-RNA result greater than or equal to 10,000 IU/mL; 4. Subject must have a liver biopsy within 5 years of Day 1 with histology consistent with chronic hepatitis and no other etiology for chronic liver disease. A copy of the local pathology report must be available in the site’s file; 5. Subject and subject's partner(s) must each agree to use acceptable methods of contraception 2 weeks prior to Day 1 and at least 6 months or longer if dictated by local regulations after last dose of study drug (see Section 7.6.1). In section 7.6.1 the study protocol defines that females must be using one of the following methods of birth control: a. diaphragm, b. tubal ligation, c. intrauterine device (IUD), d. sponge and spermicide, e. appropriate contraception registered for marketing containing an estrogen and/ or progesterone agent (oral, transdermal, intramuscular, or implant).
As the use of a diaphragm, a non-hormonal intrauterine device (IUD) or a sponge and spermicide as birth control method is not safe enough according to the Note for guidance on non-clinical safety studies for the conduct of human clinical trials for pharmaceuticals (CPMP/ICH/286/95), the following change in section 7.6.1. of the study protocol will apply:
Sexual-active females of childbearing potential who use a diaphragm, a non-hormonal intrauterine-device (IUD) or a sponge and spermicide will not be included into the study.
6. Subjects must be willing to give written informed consent

If subject's marijuana use is not deemed excessive and does not interfere with life, subject must be instructed to discontinue any current use of recreational marijuana prior to entry into study and throughout the study period. 7. Any known pre-existing medical condition that could interfere with the subject’s participation in and completion of the study as specified in the protocol. 8. Evidence of active or suspected malignancy, or a history of malignancy, within the last 5 years (except adequately treated basal cell carcinoma of the skin) 9. Subjects who are pregnant or nursing. Subjects who intend to become pregnant during the study period. Male subjects with partners who are, or intend to become, pregnant during the study period 10. Any other condition which, in the opinion of the Principal Investigator, or physician listed in FDA Form 1572 would make the subject unsuitable for enrollment or could interfere with the subject participating in and completing the study. 11. Participation in any other clinical trial within 30 days of the screening visit or intention to participate in another clinical trial during participation in this study. Collection of additional blood, urine, or tissue samples or additional data, beyond that specified in this protocol, is prohibited (other than that related to subject’s medical care). 12. Treatment with any investigation drug within 30 days of screening visit in this study. 13. Subjects who are part of the site personnel directly involved with this study. 14. Subjects who are family members of the investigational study staff.
Laboratory Exclusion Criteria NOTE: If any of the laboratory exclusion criteria are met, then the site may have the subject retested. If a single value is more than 10% outside the listed laboratory exclusion criterion value, the clinical significance of this value may be discussed with the sponsor’s Project Physician for enrollment consideration. 15. Hematologic, biochemical, and serologic criteria (growth factors may not be used to achieve study entry requirements: a. Hemoglobin <12 g/dL for females and <13 g/dL for males b. Neutrophils <1500/mm3 (Blacks: <1200mm3) c. Platelets <100,000/mm3 d. Direct Bilirubin >1.5 x ULN (upper limit of normal) of the laboratory reference range. Total bilirubin >1.6 mg/dL unless history if Gilbert’s disease. If Gilbert’s disease is the proposed etiology, this must be documented in the subject’s chart. 16. Serum albumin <LLN (lower limit of normal) of laboratory reference range 17. Thyroid stimulating hormone (TSH) >1.2 x ULN or <0.8 x LLN of laboratory reference range (subject can use thyroid medication to be in an acceptable TSH range and subject must be clinically euthyroid) 18.

E.5 End points |
E.5.1 | Primary end point(s) |
