Summary
This 3-arm study assessed the safety and efficacy of combination treatment with peginterferon alfa-2a + ribavirin in participants with chronic hepatitis C. Three groups of participants were studied; 1) those with elevated alanine transaminase (ALT) levels, 2) those with normal ALT levels, and 3) those with human immunodeficiency virus (HIV) co-infection. Participants with genotype 1, 4, 5 or 6 received peginterferon alfa-2a 180 micrograms (mcg) subcutaneous (SC) once weekly (qw) + ribavirin 1000-1200 milligrams (mg) orally (PO) daily (dependent on body weight) for 48 weeks. Those with genotype 2 or 3 received peginterferon alfa-2a 180 mcg SC qw + ribavirin 800 mg PO daily for 24 weeks, and all participants with HIV co-infection received peginterferon alfa-2a 180 mcg SC qw + ribavirin 800 mg PO daily for 48 weeks.

(RNA)

- Scheduled for treatment with peginterferon alfa-2a

- Compensated liver disease

- Women in fertile age must be informed about obligation of using adequate contraception
during and 6 months post treatment with ribavirin (Copegus®)

- Men with a sexual partner in fertile age must be informed about obligatory
contraception preventing pregnancy during the course of treatment with ribavirin
(Copegus®) as well as 6 months after treatment cessation

sooner than within 2 weeks preceding the planned inclusion to the study

- Men with a sexual partner in fertile age must produce a negative result of the
partner's pregnancy test performed not sooner than within 2 weeks preceding the
planned partner's inclusion to the study

Exclusion Criteria:

- Therapy with any systemic antiviral, antineoplastic or immunomodulatory treatment less
than or equal to (<=) 6 months prior to first dose of study drug

participants (the result must not be older than 2 weeks prior to inclusion to the
study)

- Platelet count <90 x 10^9/liter (the result must not be older than 2 weeks prior to
inclusion to the study

- Neutrofil count <1.5 x 10^9/liter (the result must not be older than 2 weeks prior to
inclusion to the study)

- Participants with increased risk of anaemia, or participants at risk of serious health
problems resulting from anaemia or decrease of hemoglobin (e.g., participants with
serious cardiovascular or cerebrovascular disease)

- History or presence of a serious mental disease, especially depression, which, in the
investigator's opinion, does not allow administration of peginterferon alfa-2a
(Pegasys®)
