|---|---|---|---|
| Primary | Number of Participants With Sustained Virologic Response (SVR) in the Double-blind (DB) Antiviral Treatment Phase | From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3) | Participants with SVR are defined as those with non-detectable Hepatitis C Virus (HCV) ribonucleic acid (RNA) at the end of treatment and all subsequent planned visits up to 24 weeks post-completion of the treatment period of the DB Phase. |
| Secondary | Number of Participants Whose Platelet Count Increased From a Baseline Count of <75 Gi/L to a Count Greater Than or Equal to (>=) 100 Giga (10^9) Cells Per Liter (Gi/L) During the Open-label (OL) Pre-Antiviral Treatment Phase | From Baseline up to Week 9 in the OL Phase | Participants were assessed for a shift from a baseline platelet count of \<75 Gi/L to a count \>=100 Gi/L during the OL Phase (up to 9 weeks). Local laboratories were used for platelet function tests. Platelet counts were measured by blood draw. |
| Secondary | Number of Participants Receiving the Indicated Doses of Eltrombopag in the OL Phase Who Initiated Antiviral Therapy (Peginterferon Alfa-2a and Ribavirin) in the DB Phase | From Baseline up to Week 9 in the OL Phase | In the OL Phase, participants initially received the lowest dose of eltrombopag (25 mg QD) for 2 weeks. If after this time the platelet count was \<100 Gi/L, participants underwent sequential dose escalation to the next highest dose (50 mg QD for up to 2 weeks), with further dose escalations to 75 mg QD (up to 2 weeks) and 100 mg QD (up to a maximum of 3 weeks) if platelet counts remained \<100 Gi/L. Participants who achieved platelet counts \>=100 Gi/L when receiving any of the eltrombopag doses in the OL Phase initiated antiviral therapy in the DB Phase. |

| Secondary | Number of Participants With End of Treatment Response (ETR) and Sustained Virological Response at Week 12 of Follow-up (SVR12) During the DB Phase | From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3) | ETR is defined as the absence of detectable HCV RNA at the end of antiviral treatment. SVR12 is defined as the absence of detectable HCV RNA at the end of antiviral treatment and the 12-week follow-up assessment. |
| Secondary | Number of Participants in the Indicated Categories for Antiviral Therapy Dose Reductions in the DB Phase | From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3) | Participants were assigned a score equal to the number of times their dose of antiviral therapy (peginterferon or ribavirin) was reduced (0=no dose reductions \[DRs\]; 1=one DR; 2=two DRs; 3=three DRs; \>3=more than three DRs). When possible, every effort was made to maintain the recommended dose of antiviral therapy for the treatment duration in the DB Phase. However, when dose modification of antiviral therapy was required due to safety concerns, it was performed by the Investigator as per the region-specific product labels of peginterferon and ribavirin. |
| Secondary | Time to First Dose Reduction of Peginterferon Alfa-2a and Ribavirin Therapy in the DB Phase | From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3) | Time to first dose reduction was calculated as the time period from the first dose to the first dose reduction. |
| Secondary | Number of Participants With the Indicated Levels of Peginterferon Dose Reductions in the DB Phase | From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3) | The assigned dose in the DB Phase of peginterferon alfa-2a was 180 micrograms (µg). For peginterferon dose modification, downward adjustments in one-level increments were considered. The lowest dose of peginterferon alfa-2a that was allowed to be administered was 45 µg. When dose adjustment was required for moderate to severe adverse reactions (clinical and/or laboratory), an initial dose reduction to 135 µg was generally adequate. In some cases, a dose reduction to 90 µg or 45 µg was necessary. Dose increases toward the original dose were considered when the adverse reaction was resolved. |
| Secondary | Number of Participants Who Prematurely Discontinued Antiviral Therapy in the DB Phase | From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3) | The following participants were considered to have discontinued antiviral therapy: participants who were lost to follow-up; participants who withdrew for any reason; participants who died; participants who otherwise did not complete their planned course of antiviral therapy for any reason. The planned duration of antiviral therapy was 48 weeks for participants with Non-Genotype 2/3 and 24 or 48 weeks for participants with Genotype 2/3. |
| Secondary | Number of Participants Categorized as Responders (R) and Non-responders (NR) for SVR and RVR to Antiviral Therapy in the Indicated Variants of Interleukin 28B (IL28B) (or Interferon, Lambda 3) | From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3) | There are two genetic variants (rs12979860 and rs8099917) mapping near IL28B associated with both interferon-induced SVR and spontaneous HCV clearance. IL28B genotype distribution by response to antiviral therapy (SVR/RVR responders: those who achieved SVR/RVR; SVR/RVR non-responders: those who did not achieve SVR/RVR) was assessed. The effect of genotype was tested by comparing participants that carried 2 copies of the IL28B favorable response allele versus the others (recessive model). Genotypes at rs12979860 were coded as: CC=1, CT or TT=0; rs8099917 was coded as TT=1, GT or GG=0. |

The number of participants with a CS and a NCS change from baseline in ECG status, as determined by the Investigator, was reported. CS, ECG with a CS abnormality that meets exclusion criteria. NCS, ECG with an abnormality not CS or meeting exclusion criteria, per Investigator, based on reasonable standards of clinical judgment. "Not applicable" indicates that information was not provided by the investigator on whether the change from baseline ECG was CS or NCS. |
| Secondary | Mean Change From Baseline in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) at the Indicated Time Points During the DB Phase | DB Phase: Baseline; Weeks 1, 2, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, and 44; End of Treatment (up to Week 48); 4-week Follow-up (FU) (up to Week 52); 12-week FU (up to Week 60); and 24-week FU (up to Week 72) | Participant's blood pressure was measured at the indicated time points during the study. Systolic blood pressure is a measure of blood pressure while the heart is beating. Diastolic blood pressure is a measure of blood pressure while the heart is relaxed. Mean change from Baseline was calculated as the value at the indicated time points minus the value at Baseline. |
