Study Endpoints

Primary Endpoints

Number of Participants Achieving Responder Status at 24 Weeks of Treatment
Up to 24 weeks

The number of participants achieving responder status at 24 weeks of treatment was assessed. A participant was classified as a responder if, at 24 weeks of treatment, they met both of the following criteria: 1) HCV-Ribonucleic Acid (RNA) negative (defined as \<100 copies/mL serum by quantitative polymerase chain reaction \[qPCR\] assay); and 2) alanine transaminase (ALT) level normal.

Number of Participants Achieving Sustained Responder Status at 24 Weeks of Follow-up
Up to 72 weeks (up to 48 weeks treatment and 24 weeks follow-up)

The number of participants achieving sustained responder status at 24 weeks of follow-up was assessed. A participant was classified as a sustained responder if, at 24 weeks of follow-up, they met both of the following criteria: 1) HCV-RNA negative (defined as \<100 copies/mL serum by qPCR assay); and 2) ALT level normal.

Area Under the Curve (AUC) of PEG-Intron at 12 Weeks
Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks

AUC was defined as the actual body exposure to drug after administration of a dose of the drug.

Maximum Serum Concentration (Cmax) of PEG-Intron at 12 Weeks
Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks

Cmax was defined as observed maximum plasma concentration.

Average Concentration Within the Dosing Interval (Cavg) of PEG-Intron at 12 Weeks
Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks

Cavg was defined as average plasma concentration.

Minimum Serum Concentration (Cmin) of PEG-Intron at 12 Weeks
Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks

Cmin was defined as observed minimum plasma concentration.

Observed Time to Achieve Cmax (Tmax) of PEG-Intron at 12 Weeks
Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks

Tmax was defined as time of maximum plasma concentration.

Apparent Clearance(CL/F) of PEG-Intron at 12 Weeks
Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks

CL/F was defined apparent clearance - the volume of plasma in the vascular compartment cleared of drug per unit of time and per kilogram of body weight by the processes of metabolism and excretion.
