A Study to Assess Efficacy and Safety of Eltrombopag in Combination With a Short Course of Dexamethasone in Patients With Newly Diagnosed ITP

A Phase II, Randomized (1:1) Open Label Study to Assess the Efficacy and Safety of Eltrombopag in Combination With Dexamethasone Compared to Dexamethasone, as First-line Treatment in Adult Patients With Newly Diagnosed Immune Thrombocytopenia

ClinicalTrials.gov Identifier: NCT04346654

All compounds are either investigational or being studied for (a) new use(s). Efficacy and safety have not been established. There is no guarantee that they will become commercially available for the use(s) under investigation.

Study Description

The purpose of this study is to compare the ability of eltrombopag in combination with a short course of high-dose dexamethasone to induce sustained response off treatment in patients with newly-diagnosed ITP versus 1-3 cycles of dexamethasone monotherapy.

The unmet clinical need and the potential for eltrombopag when added to steroids to improve the treatment outcome and the potential to induce sustained response off treatment serve as the basis for clinical investigation of eltrombopag in first-line ITP.
