Number of Participants With Non-Serious Adverse Events (AEs) And Serious Adverse Events (SAEs) [ Time Frame: From signing of informed consent up to end of study (up to Week 72) ]
An AE was any untoward medical occurrence in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Number of participants with non-serious AEs were exclusive of serious AEs.
Adverse events; laboratory parameters [ Time Frame: Throughout study; recorded at each clinic visit ]

  • Percentage of Participants With Sustained Virological Response (SVR) at 24 Weeks After End of Therapy [ Time Frame: 24 weeks after end of therapy (Week 72) ]
    SVR at 24 weeks after end of therapy was defined as a negative result of HCV Ribonucleic Acid (HCV RNA) qualitative assay 24 weeks after end of therapy. Percentage of participants with SVR was calculated as [number of participants with negative results of HCV RNA qualitative assay 24 weeks after end of therapy divided by the total number of participants analyzed] multiplied by 100. The participants who failed to undergo tests at 24 weeks after completion of therapy were considered not amenable to therapy.
  • Percentage of Participants With Undetectable HCV RNA at Weeks 12, 24 and 48 After Therapy Initiation [ Time Frame: Weeks 12,24 and 48 After Therapy Initiation ]
    HCV RNA levels of < 50 International Units per milliliter (IU/mL) were defined as undetectable HCV RNA. The percentage of participants with undetectable HCV RNA was calculated as [number of participants with undetectable HCV RNA divided by the total number of participants analyzed] multiplied by 100 for Weeks 12, 24 and 48.
  • Percentage of Participants With Change in Hemoglobin Level [ Time Frame: Baseline, Weeks 2, 4, 8, 12, 24, 36, 48 and follow-up Weeks 4 (Week 52), 12 (Week 60), and 24 (Week 72) ]
    Change in hemoglobin level (compared to baseline) was reported as "significant decrease", "Normal" (no change), "Increase", "Decrease", and "Missing". Significant decrease was defined as per Investigator's discretion.
Sustained viral response [ Time Frame: 24 weeks after end of therapy ]

Safety and Tolerability of Ribavirin (RO 20-9963) in Combination With Peginterferon Alfa-2a (40 kD)in Patients With Chronic Hepatitis C
This single arm study will evaluate the safety and tolerability of ribavirin in combination with PEGASYS in patients with chronic hepatitis C. Patients will receive ribavirin 800mg, or 1000-1200mg po daily, according to HCV genotype and body weight (< and >75kg)in combination with PEGASYS 180micrograms sc weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is >500 individuals.
