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 COMPARATOR1000 mg daily in patients weighing \<75 kg and 1200 mg daily in patients weighing ≥ 75 kg
Concentration-Controlled Ribavirin Dosing
EXPERIMENTALDose adjusted based on first dose AUC0-12
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
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
