"End of EXTEND: Observing for Cure in Patients With Chronic ITP"
This study proposes to observe whether a stable platelet count would be maintained without additional treatment in the long term in at least a proportion of patients who have discontinued eltrombopag taken for at least 4 months. This requires that if patients stop treatment with eltrombopag, they are not immediately transitioned to further treatment unless it is necessary.
The objective of the study is to assess how frequently patients who have discontinued eltrombopag attain a stable, treatment-free, unmaintained adequate platelet count 4 to 8 weeks after discontinuing eltrombopag and how long such a response lasts (if it occurs).
