Key information

About this study

This is an open-label (all people know the identity of the intervention), multicenter study in genotype 1 chronic HCV infected liver transplant patients who will be treated for 12 weeks with telaprevir 750 mg every 8 hours given in combination with Peg-IFN-alfa-2a and ribavirin followed by 36 weeks of treatment with Peg-IFN-alfa-2a and ribavirin alone. The total treatment duration will be 48 weeks. Safety will be evaluated throughout the study and will include evaluations of adverse events, clinical laboratory tests, electrocardiogram, vital signs, and physical examination.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • First time liver transplant recipient whose primary pre-transplant diagnosis was chronic hepatitis C genotype 1
  • More than 6 months to 10 years post-liver transplant
  • Patient did or did not receive treatment for HCV prior to liver transplantation
  • Patient must agree to have a liver graft biopsy during the screening period unless they had a biopsy within three months of the screening period (for patients between 6 months and one year post transplant) or within six months of the screening period (for patients who are more than one year post transplant)
  • A female patient of childbearing potential and a nonvasectomized male patient who has a female partner of childbearing potential must agree to the use of 2 effective methods of birth control from screening until 6 months (female patient) or 7 months (male patient) after the last dose of ribavirin

Exclusion criteria

  • Patient is currently infected or co-infected with HCV of another genotype than genotype 1
  • Patient received treatment for hepatitis C following liver transplantation
  • Patient has history of decompensated liver disease or shows evidence of significant liver disease in addition to hepatitis C
  • Patient with human immunodeficiency virus or hepatitis B virus co-infection
  • Patient with active malignant disease or history of malignant disease within the past 5 years (with the exception of treated basal cell carcinoma or hepatocellular carcinoma)

Treatment and study plan

Telaprevir

Drug

Type=exact number, unit=mg, number=375, form=tablet, route=oral. Patients will receive 2 oral tablets (750 mg) every 8 hours for 12 weeks.

Pegylated interferon alfa-2a

Drug

Type=exact number, unit=µg, number=180, form=injection, route=subcutaneous. 180 microgram (µg) per week, subcutaneous injection, for 48 weeks.

Ribavirin

Drug

Type=exact number, unit=mg, number=200, form=tablet, route=oral. Starting from 600 mg (3 tablets) per day on Day 1. This dose will become higher or lower based on blood results and the investigators opinion (to a goal of 1000 to 1200 mg/day [5 to 6 tablets] based on subject weight), twice daily regimen, for 48 weeks.

Primary outcomes

  1. Number of patients achieving sustained virologic response (SVR) 12 planned

    Time frame: Week 60

    SVR12 planned is defined as having plasma hepatitis C virus (HCV ) ribonucleic acid (RNA) level less than 25 IU/mL 12 weeks after the last planned dose of study medication.

Secondary outcomes

  1. Number of patients achieving SVR12 planned(c)

    Time frame: Week 60

    SVR12 planned(c) is defined as having undetectable plasma HCV RNA levels 12 weeks after the last planned dose of study drugs.

  2. Number of patients achieving SVR24 planned

    Time frame: Week 72

    SVR24 planned is defined as having plasma HCV RNA levels less than 25 IU/mL 24 weeks after the last planned dose of study medication.

  3. Number of patients achieving SVR24 planned(c)

    Time frame: Week 72

    SVR24 planned(c) is defined as having an undetectable plasma HCV RNA level 24 weeks after the last planned dose of study medication.

  4. Number of patients having an undetectable HCV RNA level at Week 4 of treatment

    Time frame: Week 4

  5. Number of patients having an undetectable HCV RNA level at Week 12 of treatment

    Time frame: Week 12

  6. Number of patients having undetectable HCV RNA levels at Week 4 and Week 12 of treatment

    Time frame: Week 4 and Week 12

  7. Number of patients having an undetectable HCV RNA level at the actual end of treatment

    Time frame: Week 48

  8. Number of patients having an undetectable HCV RNA level at the planned end of treatment

    Time frame: Week 48

  9. Number of patients having less than 25 IU/mL at the planned end of treatment

    Time frame: Week 48

  10. Number of patients with on-treatment virologic failure

    Time frame: Week 48

    Virologic failure is defined as patients who meet a virologic stopping rule and/or meet the definition of viral breakthrough.

  11. Number of patients with relapse after undetectable HCV RNA at actual end of treatment

    Time frame: Week 48

    Number of patients who relapse, defined as having confirmed detectable HCV RNA during the follow-up period after previous undetectable HCV RNA (less than 25 IU/mL, target not detected) at actual end of treatment.

  12. Number of patients with relapse after undetectable HCV RNA at planned end of treatment

    Time frame: Week 48

    Number of patients who relapse, defined as having confirmed detectable HCV RNA during the follow-up period after previous undetectable HCV RNA (less than 25 IU/mL, target not detected) at planned end of treatment.

  13. Number of patients with relapse after previous HCV RNA less than 25 IU/mL at planned end of treatment

    Time frame: Week 48

    Number of patients who relapse, defined as having confirmed detectable HCV RNA during the follow-up period after previous HCV RNA less than 25 IU/mL at planned end of treatment.

  14. Number of patients with viral breakthrough

    Time frame: Week 48

    Number of patients with viral breakthrough (defined as an increase more than 1 log in HCV RNA level from the lowest level reached, or a value of HCV RNA more than 100 IU/mL in patients whose HCV RNA has previously become less than 25 IU/mL during treatment).

  15. Change from baseline in log HCV RNA values
