A Rollover Study to Provide Continued Treatment With Eltrombopag

This Phase IV, multicenter, non-randomized, open-label, uncontrolled, rollover study was designed to provide continued access to eltrombopag to eligible subjects. As this study was a rollover study, the subjects were enrolled into this study from the parent studies. There were 3 cohorts in this study: Cohort A: Adult subjects who have completed study treatment with eltrombopag during their participation in a parent study for MDS/AML (i.e., 114968/ASPIRE and PMA112509). Cohort B: Adult subjects who have completed study treatment with eltrombopag during their participation in a parent study for ITP (i.e., TRA105325/EXTEND). Cohort C: Pediatric subjects who have completed study treatment with eltrombopag during their participation in a parent study for ITP. Once a subject turned 18 years of age, they might remain in the study and follow the Cohort B procedures. No pediatric subjects were enrolled in this cohort/study. The study consisted of a transition visit, study treatment visits, and a follow-up visit. Subjects in Cohort A and Cohort B completed the Transition visit assessments and then returned for their next schedule visit as per the Visit schedule. In the study treatment visit, subjects received a starting dose of eltrombopag at the same dose and administration that they were receiving at the time of their last study treatment visit in the parent study. Safety was evaluated through physical examinations, clinical laboratory tests, and monitoring of adverse events. Additional safety assessments were done as per standard of care and/or when medically indicated. Assessment of clinical benefit was performed throughout the study using local standard of care as determined by the Investigator to determine continued study participation and treatment with eltrombopag. Only subjects considered by the Investigator to be receiving clinical benefit without unacceptable toxicity may continue on study treatment. Once treatment with eltrombopag was permanently discontinued, the subject would attend the follow-up visit.
