NCT01097395

Brief Summary

The purpose of this study is to determine if concentration-controlled ribavirin dosing can achieve a targeted level of plasma exposures and if it appears safe and effective compared with standard weight-based ribavirin dosing. Forty, previously treatment-naive participants with genotype 1 disease will be randomized to receive concentration-guided or standard weight-based ribavirin. Peginterferon alfa 2a,ribavirin, and telaprevir will be provided through the study.

Outcome Measures

Primary Outcomes (1)

  • Ribavirin AUC-12 Variability

    Demonstrate that concentration-controlled ribavirin dosing can achieve a targeted level of plasma exposure with reduced variability in the steady-state area-under-the-concentration-time curve (AUC0-12) compared with standard weight-based ribavirin dosing

    steady state (~weeks 9-10)

Secondary Outcomes (2)

  • Safety - Absolute Hemoglobin Declines

    from baseline through end of treatment, up to 48 weeks

  • Sustained Virologic Response (i.e., Cure)

    assessed 12 weeks after stopping treatment

Study Arms (2)

Standard Weight-Based Ribavirin Dosing

ACTIVE COMPARATOR

1000 mg daily in patients weighing \<75 kg and 1200 mg daily in patients weighing ≥ 75 kg

Drug: ribavirin

Concentration-Controlled Ribavirin Dosing

EXPERIMENTAL

Dose adjusted based on first dose AUC0-12

Drug: ribavirin

Interventions

Randomization to standard weight based ribavirin dosing (1000 or 1200 mg daily) or concentration-guided dosing based on first dose AUC0-12

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Chronic HCV-infected men and women
  • years
  • HCV genotype 1
  • Deemed ready for HCV treatment by hepatology provider and patient

You may not qualify if:

  • previous treatment with interferon, peginterferon, investigational HCV drugs, boceprevir, or ribavirin;
  • baseline absolute neutrophil count (ANC) \< 1000/mm3,
  • platelets \< 100,000/mm3,
  • hemoglobin \< 12 g/dL for women and \< 13 g/dL for men;
  • HIV positive serostatus;
  • HBV positive serostatus;
  • decompensated liver disease (i.e., ascites, history of esophageal variceal bleeding, hepatic encephalopathy);
  • autoimmune hepatitis
  • hemoglobinopathy (e.g., sickle cell anemia, thalassemia)
  • Cockcroft and Gault estimated creatinine clearance \< 50 mL/min;
  • alcohol or illicit drug use that in the opinion of the investigator would interfere with study participation and/or impact study results
  • for females, active pregnancy or any intent to become pregnant during study period or for up to 6 months after completing treatment
  • for males, a pregnant female partner or intent to impregnate a female during study period or for up to 6 months after completing treatment
  • for both sexes an unwillingness to use two forms of contraception during the study period and for 6 months after completing treatment. While on telaprevir and for 2 weeks following discontinuation of telaprevir, females must use two non-hormonal forms of contraception;
  • history of significant or unstable cardiac disease including severe coronary artery disease (unstable angina, recent myocardial infarction, chest pain with exertion) or congestive heart failure;
  • +7 more criteria
