Peginterferon Alfa-2a + Ribavirin

Participants received Peginterferon alfa-2a (40 kD) \[Pegasys\] at a dosage of 180 microgram (μg), subcutaneously (SC), once a week plus Ribavirin \[Copegus\] 1000 or 1200 milligram (mg)/day), orally, \[according to body weight, lesser than or greater than/equal to (\< or \>/=) 75 kilogram (kg), respectively\] twice daily during the randomized treatment period for 12 weeks. Participants who completed the randomized treatment period of 12 weeks and wished to continue therapy were given Peginterferon alfa-2a 180 μg SC once weekly plus Ribavirin 1000 or 1200 mg/day orally (\< or \>/=75 kg body weight, respectively twice daily for an additional 36 weeks to complete a full 48-week treatment course. After treatment completion, participants were followed-up for safety for 24 weeks.

Participants who completed the randomized treatment period of 12 weeks and wished to continue therapy were given Peginterferon alfa-2a 180 μg SC once weekly plus Ribavirin 1000 or 1200 mg/day orally (\< or \>/=75 kg body weight, respectively) twice daily for an additional 36 weeks to complete a full 48-week treatment course.
