What was measured

The maximum duration for which a participant continuously maintained a platelet count of \>=50 Gi/L was calculated and summarized for the 24 weeks of eltrombopag dosing (Part 2). Participants with non-weekly assessments were assumed to have maintained a positive response for each week between two assessments that had positive responses. If the participant achieved a positive response at an assessment and then achieved a negative response at the next assessment, then it was assumed that the participant had achieved a positive response for one day.

Analysis population: ITT Population. Only those participants who entered into Part 2 (Open-label eltrombopag-only phase) were analyzed.

Groups in this outcome

Part 2 (Open-Label Period) - Eltrombopag

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: aged between 6 and 17 years with a 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. Participants aged between 1 and 5 years received eltrombopag 1.2 mg/kg QD and; participants of East Asian ancestry received a starting dose of eltrombopag 0.8 mg/kg/day.
