Boceprevir Drug Combination for Hepatitis C Treatment in People With and Without HIV

• INCLUSION CRITERIA:

To be eligible for participation on this protocol, a participant must satisfy all of the following conditions:

1. Be greater than or equal to18 years old and have an identifiable primary care provider.
2. Have documented chronic HCV infection by demonstration of a positive test for hepatitis C antibody and HCV RNA of 2,000 IU/mL or greater.
3. Infected with HCV GT-1 virus.
4. If coinfected, have either documentation of HIV-1 infection by licensed enzyme-linked immunosorbent assay (ELISA) confirmed by a Western Blot or history of HIV RNA of 1,000 copies/mL or greater.

5. If coinfected, must meet one of the following prior to enrollment:

   1. If on a stable non-NNRTI or non-PI antiretroviral regimen that HAS NOT changed within the past 6 months, must have an HIV-1 VL of less than 400 copies/mL for at least 3 months; or
   2. If on a current antiretroviral regimen that HAS changed within the past 6 months, have an HIV-1 VL of less than 50 copies/mL for at least 3 months; or
   3. Be a long-term nonprogressor as documented in the medica record.
6. Have histopathologic features consistent with chronic HCV infection at the time of enrollment. A liver biopsy within 3 years (36 calendar months) prior to screening may be used as the baseline biopsy. Participants can opt out of a liver biopsy if they had one more than 3 years prior and have a contraindication, such as receipt of chronic anticoagulation therapy. Participants with decompensated liver disease are excluded from the study.
7. Are na ve to prior IFN-based treatment for HCV.
8. Have CD4 cell counts greater than or equal to 100 cells/mm(3).
9. Willing to have genetic testing.
10. Not pregnant or breastfeeding. Serum pregnancy test must be negative at screening for female participants.

11. Agree not to become pregnant if a female of childbearing potential while on the study and for at least 6 months after stopping RBV. Because of the potential teratogenic effects of RBV treatment, subjects and their partners must remain abstinent or use two methods of birth control, which may be selected from the following list (oral contraceptive concentrations are decreased, and may not be effective when used during BOC treatment and, therefore, are not included in this list):

    Surgical sterilization of either partner

    Intrauterine device

    Male or female condoms with or without a spermicide

    Diaphragm, cervical cap, or sponge

12. Male participants who are not documented to be sterile must agree to either abstain from intercourse or consistently use a condom while their female partner (if applicable) agrees to use one of the appropriate medically accepted methods of birth control listed above from the date of screening until 6 months after the last dose of RBV.
13. Be able and willing to either learn to safely inject medication or find another person to inject the medication for him/her.
14. Be willing to allow storage of blood or tissue samples for future research.

Exclusion of Children:

Because there are insufficient data regarding the safety and efficacy of BOC, PEG, or RBV in the pediatric population, children are excluded from this study.

Exclusion of Women:

Pregnancy: Pregnant women are excluded from this study because the effects of BOC, PEG, and RBV on the developing human fetus are unknown. Preclinical animal data indicate that the use of RBV treatment during pregnancy is potentially teratogenic.

Breastfeeding: Because there is an unknown but potential risk for adverse effects in nursing infants secondary to treatment of the mother with BOC, PEG, or RBV, breastfeeding women are excluded from this study.
