30 Participants

SECONDARY outcome

Timeframe: up to 12 weeks

Population: Participants who completed study. Statistical tests were not completed because a) Difficulty in obtaining accurate information on the reasons for platelet transfusion in the historical cohort and b) Several participants had platelet counts higher than threshold for starting transfusion, making comparisons not meaningful

Defined as the average number of days from the first day of eltrombopag until the first of five consecutive days with platelet counts \>= 50,000 /µL without a platelet transfusion. The time will be summarized using the Kaplan-Meier method and will use the logrank test and proportional hazards models.

Population: Participants who completed study

The number of participants with a sustained improvement of platelet counts (independent of platelet transfusions) seen by at least a doubling of platelet count from the pretreatment thrombocytopenic level (defined as \< 10000 /µL, ) or an absolute increase in platelet counts to between 30000 /µL and 50000 /µL, whichever is higher but not achieving complete response. Or if there is a need to restart eltrombopag due to drop in platelet count to below 50000 /µL following interruption of eltrombopag therapy after achieving platelet counts of \> 100000 /µL on the drug.
