About this trial

This is an interventional treatment trial for HCV Infection

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria

Main Selection Criteria for Healthy Volunteers:

  • Subject has provided written consent.
  • Subject is in general good health.
  • Females must be post-menopausal for at least 2 years or surgically sterile.
  • Females must not be pregnant or breast-feeding. If male, subject is surgically sterile or practicing specific forms of birth control.

Main Selection Criteria for HCV Genotype 1-infected Volunteers:

  • Subject has provided written consent.
  • Subject has chronic HCV genotype 1 infection at screening.
  • Liver biopsy within 3 years with histology.
  • Females must be post-menopausal for at least 2 years or surgically sterile.
  • Females must not be pregnant or breast-feeding. If male, subject is surgically sterile or practicing specific forms of birth control.
  • Subject is in general good health, as perceived by the investigator, other than HCV infection.

Main Selection Criteria for Volunteers in the Resistance Monitoring Portion of the Study:

  • Subject has provided written consent, has received at least one dose of ABT-267 or placebo in the study, and is considered suitable by the investigator to participate.

Exclusion Criteria

Main Exclusion Criteria for Healthy Volunteers:

  • Positive test for HAV IgM, HBsAg, HCV Ab or HIV Ab.
  • Clinically significant cardiovascular, respiratory (except mild asthma), renal, gastrointestinal, hematologic, neurologic, thyroid, or any uncontrolled medical illness or psychiatric disorder.
  • Use of tobacco or nicotine-containing products with the 6-month period prior to study drug administration.
  • Abnormal screening laboratory results.
  • Significant sensitivity to any drug.
  • Requirement for any over the counter and/or prescription medication, vitamins and/or herbal supplements on a regular basis.

Main Exclusion Criteria for HCV Genotype 1-infected Volunteers:

  • Significant sensitivity to any drug.
  • Positive HBsAg, HAV-IgM, and HIV Ab. Use of CYP enzyme inducers or inhibitors within 1 month of dosing.
  • Clinically significant cardiovascular, respiratory (except mild asthma), renal, gastrointestinal, hematologic, neurologic, thyroid disease (except hypothyroidism on stable thyroid replacement therapy), or any uncontrolled medical illness or psychiatric disorder.
  • Use of any medications (prescription and over-the counter) within 2 weeks prior to study drug dosing without prior approval by the Abbott Medical Monitor.
  • Use of any vitamins or herbal supplements within 2 weeks prior to study drug dosing.
  • Prior treatment with any investigational or commercially available anti-HCV agents.
  • Abnormal screening laboratory results.

Healthy volunteers, receiving single ascending doses of ABT-267 or placebo.

Healthy volunteers, receiving multiple ascending doses of ABT-267 or placebo, OR, multiple doses of ABT-267 + single dose of a Cytochrome P450 inhibitor or placebo + single dose of a Cytochrome P450 inhibitor.

Healthy volunteers, receiving ABT-267, multi-dose, food effect.

HCV genotype 1-infected treatment naïve subjects receiving multiple ascending doses of ABT-267 or placebo monotherapy for 3 days.

HCV genotype 1-infected treatment naïve subjects, receiving at least one dose of ABT-267 or placebo in the "Antiviral Activity" arm, follow-up to monitor resistance developed to ABT-267, no treatment and only blood samples will be collected

Outcomes

Primary Outcome Measures

Analysis of pharmacokinetic variables and mean change in HCV RNA level from baseline.
Analysis of safety measures including but not limited to tabulation of adverse events, physical exam, vital signs, ECGs, continuous cardiac monitoring, and clinical lab results (including chemistry, hematology and urine).
