Outcome Measures
Primary Outcome Measures
- Number of Participants With Any Adverse Event (AE) and Any Serious Adverse Event (SAE) in Part 1 [From the start of investigational product up to the start of antiviral therapy (up to 9 weeks; median of 21 days)]
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, may jeopardize the participant or require medical or surgical intervention to prevent one of the other outcomes listed, or is an event of possible drug-induced liver injury. Refer to the general AE/SAE module for a list of AEs and SAEs.
- Number of Participants With Any AE and Any SAE in Part 2 [From the date of initiation of antiviral therapy (Antiviral Baseline Visit [between Study Day 14 and Study Day 65]) to the completion of the follow-up period (up to Week 96/WD)]

Refer to the general AE/SAE module for a list of AEs and SAEs.
- Number of Participants With the Indicated Worst-case Division of Acquired Immune Deficiency Syndrome (DAIDS) Grade Increases From Screening for the Indicated Clinical Chemistry Parameters During Part 1 [From Screening up to the start of antiviral therapy (up to 9 weeks; median of 21 days)]
Blood samples were collected for the measurement of clinical chemistry parameters. The DAIDS grades are utilized for measuring the severity of AEs. Grade 1, mild; Grade 2, moderate; Grade 3, severe; Grade 4, potentially life threatening.
- Number of Participants With the Indicated Worst-case DAIDS Grade Increases From the Antiviral Baseline Visit for the Indicated Clinical Chemistry Parameter During Part 2 [From Day 0 of Part 2 (Antiviral Baseline Visit [between Study Day 14 and Study Day 65) to the completion of the follow-up period (up to Week 96/WD)]
Blood samples were collected for the measurement of clinical chemistry parameters. The DAIDS grades are utilized for measuring the severity of AEs. Grade 1, mild; Grade 2, moderate; Grade 3, severe; Grade 4, potentially life threatening.
- Number of Participants With the Indicated Worst-case DAIDS Grade Increases From Screening for the Indicated Hematology Parameters During Part 1 [From Screening up to the start of antiviral therapy (up to 9 weeks; median of 21 days)]
Blood samples were collected for the measurement of hematology parameters. The DAIDS grades are utilized for measuring the severity of AEs. Grade 1, mild; Grade 2, moderate; Grade 3, severe; Grade 4, potentially life threatening.
- Number of Participants With the Indicated Worst-case DAIDS Grade Increases From the Antiviral Baseline Visit for the Indicated Hematology Parameters During Part 2 [From Day 0 of Part 2 (Antiviral Baseline Visit [between Study Day 14 and Study Day 65) to the completion of the follow-up period (up to Week 96/WD)]
Blood samples were collected for the measurement of hematology chemistry parameters. The DAIDS grades are utilized for measuring the severity of AEs. Grade 1, mild; Grade 2, moderate; Grade 3, severe; Grade 4, potentially life threatening.
- Number of Participants With a Decrease in Visual Acuity During Parts 1 and 2 [From the start of investigational product up to the 24-week follow-up visit after the last dose in Part 2 or early withdrawal (up to 96 weeks)]
Visual acuity (VA) is defined as acuteness or clearness of vision.
- Number of Participants With the Indicated Change in logMAR Scale Values During Parts 1 and 2 [From the start of investigational product up to the 24-week follow-up visit after the last dose in Part 2 or early withdrawal (up to 96 weeks)]
LogMAR (logarithm of the minimum angle of resolution) charts are used to measure an individual's visual acuity. LogMAR, expressed as the (decadic) logarithm of the minimum angle of resolution (range from +1.00 to -0.30), converts the geometric sequence of a traditional chart to a linear scale. As there are 5 letters per line, the total score for a line on the LogMAR chart represents a change of 0.1 log units.
- Number of Participants With a logMAR Change >=0.15 During Parts 1 and 2 [From the start of investigational product up to the 24-week follow-up visit after the last dose in Part 2 or early withdrawal (up to 96 weeks)]
LogMAR (logarithm of the minimum angle of resolution) charts are used to measure an individual's visual acuity. LogMAR, expressed as the (decadic) logarithm of the minimum angle of resolution (range from +1.00 to -0.30), converts the geometric sequence of a traditional chart to a linear scale.

Recruitment Details | 10^9 cells (Giga) per liter=Gi/L; participants=par.; polyethylene glycol=Peg; interferon=INF. |
---|---|
Pre-assignment Detail | In Part (P) 1, the treatment goal was to increase the platelet count to >=90 Gi/L. In P 2, par. continued on the selected P 1 dose of eltrombopag (dose effectively raising platelets to >=90 or >=100 Gi/L). Eltrombopag was given in combination with antiviral therapy (Peg INF alfa-2a or Peg INF alfa-2b and ribavirin) for the duration of treatment. |
Arm/Group Title | Eltrombopag |
---|---|
Arm/Group Description | In the Pre-antiviral Treatment Phase, participants (par.) with a platelet count of <75000/microliter (µL) received eltrombopag once daily for a minimum of 2 weeks and a maximum of 9 weeks in sequential dose escalations (25 milligrams [mg] for a minimum of 2 weeks, 50 mg for 1-2 weeks, 75 mg for 1-2 weeks, and 100 mg for 1-3 weeks) until platelet counts reached either >=90000/µL or 100000/µL. Par. who achieved the desired platelet count continued with eltrombopag in Part 2 along with antiviral treatment. Par. who did not achieve the desired platelet count completed the follow-up visits and were withdrawn from the study. Once the desired platelet counts were reached in Part 1 (>=90 Gi/L or >=100 Gi/L), par. continued to receive the dose of eltrombopag from Part 1 and polyethylene glycol (Peg) interferon (INF) alfa-2a (>=90 Gi/L) or Peg IFN alfa-2b (>=100 Gi/L) plus ribavirin. Dose adjustments of eltrombopag were permitted to achieve and maintain an appropriate platelet count. |

Arm/Group Description | In the Pre-antiviral Treatment Phase, participants (par.) with a platelet count of <75000/microliter (µL) received eltrombopag once daily for a minimum of 2 weeks and a maximum of 9 weeks in sequential dose escalations (25 milligrams [mg] for a minimum of 2 weeks, 50 mg for 1-2 weeks, 75 mg for 1-2 weeks, and 100 mg for 1-3 weeks) until platelet counts reached either >=90000/µL or 100000/µL. Par. who achieved the desired platelet count continued with eltrombopag in Part 2 along with antiviral treatment. Par. who did not achieve the desired platelet count completed the follow-up visits and were withdrawn from the study. Once the desired platelet counts were reached in Part 1 (>=90 Gi/L or >=100 Gi/L), par. continued to receive the dose of eltrombopag from Part 1 and polyethylene glycol (Peg) interferon (INF) alfa-2a (>=90 Gi/L) or Peg IFN alfa-2b (>=100 Gi/L) plus ribavirin. Dose adjustments of eltrombopag were permitted to achieve and maintain an appropriate platelet count. |
