What was measured
Single PK samples were collected at each visit during Part 1 Weeks 2, 4, 6, 8, 10, 12 and at each weekly or monthly visit during Part 2 Weeks 1-12 (Study Weeks 13-37). The concentration data were pooled across visits to identify population PK and variability parameter estimates and covariate effects. Cmax is defined as the maximum observed concentration. The Cmax for a 50mg dose was estimated for each cohort. From the final model, a single value of each PK parameter was estimated for each subject, and geometric mean (95% CI) values are presented for each cohort for a 50mg dose.
Analysis population: PK Population. Only those participants who provided pharmacokinetic samples were analyzed
Groups in this outcome
Eltrombopag Cohort 1 (12-17 Years)
Participants who received eltrombopag in Part 1 continued on the same dose in Part 2 unless adjustments were warranted according to the dosing guidelines. Participants who received placebo in Part 1 received Eltrombopag as per age criteria as follows:body weight \<27 kg received eltrombopag 37.5 mg QD, and those with a body weight \>=27 kg received eltrombopag 50 mg QD. Participants of East Asian ancestry received a starting dose of eltrombopag 25 mg QD.
Eltrombopag Cohort 2 (6-11 Years)
Participants who received eltrombopag in Part 1 continued on the same dose in Part 2 unless adjustments were warranted according to the dosing guidelines. Participants who received placebo in Part 1 received Eltrombopag as per age criteria as follows: body weight \<27 kg received eltrombopag 37.5 mg QD, and those with a body weight \>=27 kg received eltrombopag 50 mg QD. Participants of East Asian ancestry received a starting dose of eltrombopag 25 mg QD.
Eltrombopag Cohort 3 (1-5 Years)
Participants who received eltrombopag in Part 1 continued on the same dose in Part 2 unless adjustments were warranted according to the dosing guidelines. Participants who received placebo in Part 1 received Eltrombopag 1.2 mg/kg QD and; participants of East Asian ancestry received a starting dose of eltrombopag 0.8 mg/kg/day.
