What was measured

Platelet response was defined as having a platelet count of ≥ 50 x 10\^9/L at any time on study, excluding platelet counts within 8 weeks after receiving any rescue medications.

Analysis population: Efficacy Analysis Set, composed of all enrolled participants who received at least one dose of romiplostim

Groups in this outcome

Romiplostim in Adults

Romiplostim administered to adult participants subcutaneously weekly at doses up to 30 µg/kg based on platelet counts. After Amendment 1 the maximum weekly dose was reduced to 15 µg/kg, and after Amendment 2 the maximum weekly dose was reduced to 10 µg/kg. However, participants enrolled prior to Amendment 2 who were receiving \>10 µg/kg were permitted to remain on that higher dose, but could not increase their dose. In addition, if the participant's dose was decreased, it could not be increased to \>10 µg/kg.

Romiplostim in Pediatric Population

Romiplostim administered to pediatric participants subcutaneously weekly at doses up to 10 µg/kg based on platelet counts.
