Eltrombopag

Participants who achieved a platelet count \>=50 Gi/L for at least 6 out of 8 weeks, between Weeks 5 and 12 of Part 1, were reported.

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.

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.

Visual acuity (VA) is defined as acuteness or clearness of vision.

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.

An AE is any untoward medical occurrence in a participant, temporally associated with the use of a medical product, whether or not related to the product. An SAE is any untoward medical occurrence that, at any dose, results in death, is life-threatening, requires hospitalization or its prolongation, results in disability/incapacity, is a congenital anomaly/birth defect, or is another event considered serious. A drug-related AE is any AE that was judged to have a relationship with the study medication by the investigator. The severity of an AE is based on the investigator's clinical judgment.

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.

The percentage of evaluable participants who achieved a platelet response (defined as a platelet count between 50,000 and 400,000 microliter) at each nominal on-therapy day and 4 weeks post-treatment

Participants who achieved a platelet count \>=50 Gi/L at least once between Day 8 and Day 43 (first 6 weeks of Part 2) in the absense of rescue treatment were reported. A 95% confidence interval was calculated by the exact binomial method.

Complete blood count, platelet count by blood draw

Following PK parameters will be assessed: Area under the concentration-time curve from time zero to last time of quantifiable concentration within a subject (AUC\[0-t\]), area under the curve (concentration/time) from time 0 extrapolated to infinity (AUC\[0 inf\]), maximum observed concentration (Cmax) and time to Cmax (tmax)

Plasma eltrombopag PK Parameters: area under the concentration time-curves from time zero to infinity AUC(0-infinity) and maximum concentration (Cmax).

Plasma boceprevir PK Parameters: AUC from time zero to the dosing interval AUC(0-τ), Cmax, and Concentraction at end of the dosing interval (Cτ)

Plasma eltrombopag PK Parameters: AUC(0-infinity) and Cmax
