  Purpose

Background:

- Standard treatment for the hepatitis C virus (HCV) is a combination of the drugs peg-IFN and ribavirin. However, this treatment is not very effective in people with a serious type of HCV (HCV genotype 1) and also in people who have human immunodeficiency virus (HIV) coinfection. Researchers want to add a new drug, boceprevir to see if it can improve treatment results in people with both HCV genotype 1 and HIV. Boceprevir used in combination with peg-IFN and ribavirin has been recently approved for the treatment of people with HCV genotype 1 infection only, and is currently being studied in those with HIV and HCV.

Objectives:

- To test boceprevir, peg-IFN, and ribavirin as a treatment for HCV genotype 1 in people with HCV monoinfection compared to those with both HIV and HCV infections.

Eligibility:

  • Individuals at least 18 years of age who have HCV genotype 1 infection, and have not received interferon treatment for HCV
  • Half of the study participants will also have HIV infection.

Design:

  • Participants will be screened with a medical history and physical exam. They will also have blood and urine tests.
  • Participants will also have heart and liver function tests, and answer questions about mood and depression.
  • Those in the study will receive ribavirin tablets to take twice a day, and peg-IFN to inject under the skin weekly.
  • Two weeks after starting treatment, participants will have blood tests to study the treatment.
  • Four weeks after starting treatment, participants will start taking boceprevir three times a day.
  • Participants will have regular study visits with blood samples and other tests. The length of therapy will depend on the level of virus detected in the blood at several clinic visits. Those who do not respond well to the medicines at 12 weeks will stop treatment. The full length of treatment is 48 weeks.

Detailed Description:

Chronic hepatitis C virus (HCV) infection is a major public health problem with an estimated 180 million people infected worldwide. In the United States, an estimated 4.1 million people are infected and HCV is the principal cause of death from liver disease and leading indication for liver transplantation. A combination of ribavirin (RBV) and pegylated interferon (peg-IFN) is the currently recommended therapy for chronic HCV infection. However, this therapy achieves viral clearance in only 19% to 52% of patients infected with HCV genotype 1 and 76% to 80% of patients infected with genotypes 2 and 3. Current therapy is also associated with a high incidence of adverse events and low cure rates in several populations. Novel therapies that do not rely on an interferon backbone will be required to enhance cure rates in various populations. Recent data show that adding an HCV serine protease inhibitor (such as boceprevir [BOC]) to peg-IFN and RBV results in HCV eradication rates of 70% to 80% among HCV-monoinfected subjects. However, whether human immunodeficiency virus (HIV)-infected subjects will have similar rates of response to triple combination therapy is presently not known. Previous data have suggested that HIV-infected patients with chronic HCV infection have much lower eradication rates to peg-IFN and RBV than HCV-monoinfected subjects. This study will explore whether HIV/HCV-coinfected subjects have a lower response rate to a BOC/peg-IFN/RBV regimen than HCV-monoinfected subjects. Participants who have chronic hepatitis C genotype 1 monoinfection (N=50) or coinfection with HIV-1 (N=50), and who are na(SqrRoot) ve to IFN-based HCV treatment, will receive combination therapy with BOC (800 mg three times a day, every 7 to 9 hours, with food), weekly peg-IFN alpha-2b (1.5 mcg/kg/week) and twice daily RBV (weight based) for a maximum of 44 weeks, after a 4-week lead-in of peg-IFN and RBV. BOC received recent FDA approval for treating HCV monoinfection in combination with peg-IFN and RBV, and the approved labeling will be followed in this study. The primary endpoint is comparative efficacy in HCV-monoinfected and HIV/HCV-coinfected subjects. Secondary endpoints include determination of host predictors for therapeutic response, emergence of resistance biomarkers, and early viral kinetics. The findings from this study will aid in the understanding of whether HIV infection affects HCV antiviral and host responses to combination therapy using BOC/peg-IFN alfa-2b/RBV.

Criteria
  • 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(SqrRoot) ve to prior IFN-based treatment for HCV.
  8. Have CD4 cell counts greater than or equal to 100 cells/mm(3).

  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.
