About this trial

This is an interventional treatment trial for HCV Infection

Eligibility Criteria

18 Years - 60 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Males and females 18 to 60 years of age
  • No evidence of cirrhosis or have liver fibrosis corresponding to Metavir Stages 0 to 3
  • Subject's liver disease is stable with ALT values < 5 X ULN
  • Serologic evidence of detectable plasma HCV-RNA of ≥ 100,000 IU/ml at screening
  • Documented HCV Genotype 1 chronic hepatitis C.
  • Judged to be in good health on the basis of medical history and physical examination
  • All other hematology and clinical chemistry must be within normal limits or show no clinically significant abnormalities.
  • Be treatment-naïve or experienced.
  • For female subjects, must not be pregnant or breastfeeding and must be postmenopausal, surgically sterile, abstinent, or using two proven methods of birth control.
  • Sexually active male subjects, must be practicing acceptable methods of contraception during the treatment period
  • Female subjects of childbearing potential must have a negative serum ß-HCG pregnancy test at screening and a negative urine pregnancy test on Day 1 before the first dose of study drugs.
  • Agree not to participate in other clinical trials for the duration of his/her participation in this clinical trial.

Exclusion Criteria:

  • Be participating in any other clinical studies or have participated in another clinical trial within the last 30 days before study drug administration, or participation in more than 2 drug studies in the last 12 months (exclusive of the current study).
  • Be actively taking hard illicit drugs within 12 months prior to the screening visit or alcohol.
  • Have a Child-Pugh score > than 5.
  • Have evidence of liver cirrhosis including histological evidence of hepatic cirrhosis on any liver biopsy.
  • Have any cause of liver disease other than chronic hepatitis C-infection
  • Active or malignant disease or suspicion or history of malignant disease within five previous years (except for adequately treated basal cell carcinoma).
  • Have clinically significant electrocardiogram abnormalities and/or cardiovascular dysfunction within the previous 6 months
  • Have significant renal, pulmonary, gastrointestinal absorption, or neurological diseases, or neoplasia.
  • Have a history of psychiatric disorders determined by the investigator to contraindicate therapy.
  • Have uncontrolled Type 1 or Type II diabetes.
  • Antinuclear antibody titer ≥1:320.
  • Coinfection with hepatitis B and/or HIV 1 or HIV 2.

Outcomes

Primary Outcome Measures

The primary objective of this trial is to assess the antiviral activity, safety, and tolerability of VCH-916 monotherapy in adult subjects with chronic HCV-infection.

Secondary Outcome Measures

To evaluate the pharmacokinetic (PK) profile of VCH-916 in HCV-infected adults.
To establish the relationship between VCH-916 plasma levels and corresponding HCV RNA reduction with the administered dosages of VCH-916 in adults.
To study the kinetics of plasma HCV RNA following treatment for up to three(3) days with VCH-916.

5. Study Description

Brief Summary
The purpose of this study is to determine whether a 3-day course of therapy with orally administered VCH-916 given at different dosages can effectively reduce the amount of circulating virus (i.e., viral load) in patients with early-stage chronic hepatitis C-infection. This study will also evaluate the safety and tolerability of treatment with VCH-916. Blood samples will also be taken to measure the levels of VCH-916 present in plasma at various time points during the treatment period.
