Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Peginterferon alfa-2a
Treatment: Drugs - Ribavirin

Experimental: Group A - 8 weeks therapy - 8 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 2 weeks of therapy.

Experimental: Group B - 16 weeks therapy - 16 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 4 weeks of therapy.

Experimental: Group C - 24 weeks therapy - 24 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 6 weeks of therapy.

Experimental: Group D - 32 weeks (gt1) or 24 weeks (gt 2/3) - 32 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 8 weeks of therapy (genotype 1) or 24 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 8 weeks of therapy.

Experimental: Group E - 48 weeks (gt 1) or 24 weeks (gt 2/3) - 48 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 12 weeks of therapy (genotype 1) or 24 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 12 weeks of therapy (genotype 2/3).

No intervention: Untreated Group - Observation only. No treatment for hepatitis C administered. Subjects who have undetectable HCV RNA at baseline, do not wish to commence treatment or are ineligible for treatment.


Treatment: Drugs: Peginterferon alfa-2a
PEG-IFN 180 mcg in 0.5 ml (prefilled syringes) administered subcutaneously (SC) once weekly

Treatment: Drugs: Ribavirin
Genotype 1: 1000mg or 1200mg p.o. daily in split doses (1000mg for patients weighing \<75kg and 1200mg for patients weighing = 75kg) Genotypes 2/3: 800mg daily p.o. daily in split doses for genotype 2 and 3 patients

Outcomes
Primary outcome [1] 0 0
Evaluate the safety and efficacy of response-guided pegylated interferon and ribavirin for the treatment of recent HCV infection. Response-guided means the duration of treatment will be determined by the subject's early response to treatment.
Timepoint [1] 0 0
8-48 weeks

OR

B)

* i) First anti-HCV antibody or HCV RNA positive within the previous 6 months and
* ii) acute clinical hepatitis (jaundice or ALT> 10 X ULN) within the 12 months prior to first positive HCV antibody or HCV RNA with no other cause of acute hepatitis identifiable and

Treatment group only:

* Age between 16 and 18 years
* Women with ongoing pregnancy or breast feeding
* Therapy with any systemic anti-viral, anti-neoplastic or immunomodulatory treatment (including supraphysiologic doses of steroids and radiation) *6 months prior to the first dose of study drug
* Any investigational drug <6 weeks prior to the first dose of study drug
* Positive test at screening for anti-HAV IgM Ab, anti-HBc IgM Ab

* History of a severe seizure disorder or current anticonvulsant use
* History of immunologically mediated disease, chronic pulmonary disease associated with functional limitation, severe cardiac disease, major organ transplantation or other evidence of severe illness, malignancy, or any other conditions which would make the patient, in the opinion of the investigator, unsuitable for the study

Summary
Brief summary
To determine whether response guided treatment with pegylated interferon +/- ribavirin is effective for the treatment of recently acquired hepatitis C infection. Response guided treatment is when the length of treatment is determined by how quickly you respond to the treatment.
