Title: A Phase 2a, 2-Part, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Study of Telaprevir in Combination With Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) in Subjects Who Have Chronic HCV-1/HIV-1 Co-Infection and Are Treatment-Naïve for Hepatitis C
Brief Summary: The purpose of this study is to determine whether the combination of telaprevir, peginterferon alfa-2a, and ribavirin is safe and effective in treating hepatitis C virus (HCV) infection in subjects who are infected with both HCV and human immunodeficiency virus (HIV).


Options:
A: Inclusion criteria:

* Chronic hepatitis C virus (HCV) infection of genotype (GT) 1
* Parts 1-3:Treatment naive to Interferon -alfa (IFN), Pegylated interferon -alfa (PegIFN), ribavirin (RBV), and any direct acting antiviral agent for chronic hepatitis C
* Part 4: Treatment experienced with confirmed prior virological failure to an approved dose of PegIFN/RBV (null-response)
* HCV RNA \>=10,000 IU/mL at screening
* Liver biopsy within two years or fibroscan within six months prior to baseline
* Liver biopsy within two years or fibroscan within 6 months prior to screening
* Age 18-75 years

Exclusion criteria:

* Hepatitis C virus (HCV) infection of mixed genotype
* Evidence of liver disease due to causes other than chronic HCV infection
* Positive ELISA for human immunodeficiency virus (HIV)
* Hepatitis B virus (HBV) infection
* Decompensated liver disease or history of decompensated liver disease
* Active or suspected malignancy within the last 5 years

* Usage of any investigational drugs within 30 days prior to enrolment, or 5 half-lives, whichever is longer; o the planned usage of an investigational drug during the course of the current study
* Known hypersensitivity to any ingredient of the study drugs
* A condition that is defined as one which in the opinion of the investigator may interfere with the patient's capability for participation in the trial or may influence the results of the trial
* Alpha fetoprotein \>100ng/mL at screening; if \>20ng/mL and \<=100ng/mL, patients can be included if there is no evidence of liver cancer in an appropriate imaging study within 6 months prior to randomisation
* Total bilirubin \> 2 mg/dL with ratio of direct/indirect \> 1
* AST or ALT \>5xULN
* INR prolonged to \>1.7xULN
* Requirement for chronic systemic corticosteroids
* Received concomitant systemic antiviral, hematopoietic growth factor, or immunomodulatory treatment within 30 days prior to enrolment or 5 half-lives, whichever is longer
* Received silymarin or glycyrrhizin or Sho-saiko-to within 30 days prior to enrolment
* Contraindications pertaining to PegIFN or RBV
B: Inclusion Criteria:

* Chronic, genotype 1, hepatitis C with detectable HCV RNA
* HIV-1 infection for \>6 months
* Documentation of a liver biopsy within 1 year before the screening visit showing evidence of hepatitis (demonstrated by inflammation and/or fibrosis)

Exclusion Criteria:

* Previous treatment with any approved or investigational drug or drug regimen for the treatment of hepatitis C
* Previous treatment with interferon or ribavirin
* Evidence of hepatic decompensation in cirrhotic subjects
* Subjects who have participated in a clinical study involving administration of an investigational drug within 2 months
* Part A only: subjects who have been on a HAART regimen within 12 weeks before study start
C: Inclusion Criteria:

* HCV treatment-naive
* HCV RNA \> 10,000 IU/mL at screening
* Screening laboratory values within defined thresholds
* Use of two effective contraception methods if female of childbearing potential or sexually active male

Exclusion Criteria:

* Pregnant or nursing female or male with pregnant female partner
* Presence of cirrhosis
* Coinfection with HIV or hepatitis B virus (HBV)
* Current or prior history of clinical hepatic decompensation
* Chronic use of systemic immunosuppressive agents
* History of clinically significant illness or any other medical disorder that may interfere with subject treatment, assessment or compliance with the protocol
D: Inclusion Criteria:

* Patient has chronic Genotype 1 Hepatitis C infection

Exclusion Criteria:

* Subject has been previously treated for HCV
* Has Human Immunodeficiency Virus (HIV)
* Has Hepatitis B
* Has a history of clinically significant medical condition that may interfere with the study (e.g., stroke or chronic seizures or major neurological disorder) or is contraindicated for treatment with peg-IFN and Ribavirin
