What was measured

The visual acuity assessment was performed by an ophthalmologist or an optometrist under the guidance of an ophthalmologist. Visual acuity is defined as acuteness or clearness of vision. Number of participants with a change in visual acuity and change in visual acuity due to the worsening of cataracts since Baseline are presented for Part 2/3 Follow-up Visits at 3-months (FU3) and 6-months (FU6). Change in visual acuity since Baseline is displayed under the left eye but applies to both eyes. Change in visual acuity (VA) is categorized as "yes" or "no". Change due to cataracts is categorized as "yes" or "no".

Analysis population: Safety Population: all subjects who have received at least one dose of the investigational product during Part 2/3 were analyzed.

Groups in this outcome

Part 2/3 (Eltrombopag Open-Label Period) Cohort 1

All participants aged between 12 and 17 years and completing Part 2 of the study received an Open-Label treatment of eltrombopag administered as a tablet in Part 2/3. Participants who received placebo in Part 2 received 24 weeks of treatment of eltrombopag starting at 37.5 mg QD up to Week 31 of the study. Participants who received 7 weeks of eltrombopag treatment in Part 2 received an additional 17 weeks of treatment to complete a total of 24 weeks continuing at the same dosage at the end of Part 2. The maximum dose allowed was 75 mg daily. All participants enrolled in the study underwent individual dose titration based upon platelet response.

Part 2/3 (Eltrombopag Open-Label Period) Cohort 2

All participants aged between 6 and 11 years and completing Part 2 of the study received an Open -Label treatment of eltrombopag administered as a tablet in Part 2/3. Participants with difficulty swallowing a tablet in Part 2 were administered eltrombopag as a dry powder for oral suspension in Part 2/3. Participants who received placebo in Part 2 received 24 weeks of treatment of eltrombopag based on body weight up to Week 31 of the study. Participants with a body weight of \<=27 kg received 25 mg QD and participants with a body weight of \>=27 kg QD received 50 mg QD. Participants who received 7 weeks of eltrombopag treatment in Part 2 received an additional 17 weeks of treatment to complete a total of 24 weeks continuing at the same dosage at the end of Part 2. The maximum dose allowed was 75 mg daily. All participants enrolled in the study underwent individual dose titration based upon platelet response.

Part 2/3 (Eltrombopag Open- Label Period) Cohort 3

All participants aged between 1 and 5 years and completing Part 2 of the study received an Open-Label treatment of eltrombopag administered as a dry powder for oral suspension in Part 2/3. Participants who received placebo in Part 2 received 24 weeks of treatment of eltrombopag up to Week 31 of the study at 1.5 mg/kg QD. Participants of East Asian ancestry received 0.8 mg/kg/day. Participants who received 7 weeks of eltrombopag treatment in Part 2 received an additional 17 weeks of treatment to complete a total of 24 weeks continuing at the same dosage at the end of Part 2. The maximum dose allowed was 75 mg daily. All participants enrolled in the study underwent individual dose titration based upon platelet response.
