What was measured
A serious adverse event is defined as an adverse event that meets at least 1 of the following serious criteria:
* fatal,
* life threatening (places the subject at immediate risk of death),
* requires in-patient hospitalization or prolongation of existing hospitalization,
* results in persistent or significant disability/incapacity,
* congenital anomaly/birth defect, and/or
* other significant medical hazard. Adverse events were graded for severity according to the CTCAE version 3.0 grading scale, where Grade 3 = moderate, Grade 4 = life-threatening and Grade 5 = fatal.
Treatment-related adverse events (TRAEs) were those assessed by the investigator as possibly related to study drug. This relationship was determined by a "yes" or "no" response to the question: "Is there a reasonable possibility that the event may have been caused by study drug?"
Analysis population: Safety analysis set (all participants who received at least one dose of study drug)
Groups in this outcome
Placebo
Participants received weekly subcutaneous placebo for 24 weeks.
Romiplostim
Participants received once weekly subcutaneous romiplostim for 24 weeks at a starting dose of 1 µg/kg; weekly dose increases continued in increments of 1 µg/kg/week to a maximum dose of 10 µg/kg in an attempt to reach a target platelet count of ≥ 50 x 10\^9/L.
Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
