An open-label, dose-adjustment, extension study to evaluate the safety and efficacy of
eltrombopag for the treatment of subjects with idiopathic thrombocytopenic purpura (ITP) who
have previously been enrolled in an eltrombopag trial. This study will allow adjustment of
the eltrombopag dose to achieve an individualized dose and schedule for each subject. In
addition, the ability to reduce the dose of concomitant ITP medications in the presence of
eltrombopag, while maintaining platelet counts = 50,000/μL will be investigated.
