• • MDS by World Health Organization (WHO) or French-American-British (FAB) classification
• • Intermediate 1, intermediate 2 or high risk MDS by IPSS
• • At least one platelet count \< 75 Gi/L
• • Eastern Cooperative Oncology Group (ECOG) Status 0-2
• • Adequate baseline organ function defined by the criteria below: total bilirubin =\< 1.5x the upper limit of normal (ULN) except for Gilbert's syndrome or cases clearly not indicative of inadequate liver function (i.e. elevation of indirect \[haemolytic\] bilirubin in the absence of alanine aminotransferase \[ALT\] abnormality); ALT =\< 2.5xULN; creatinine =\< 2.5xULN
• • Subjects with a corrected QT interval (QTc) \<450 milliseconds (msec) or \<480msec for subjects with bundle branch block. The QTc is the QT interval corrected for heart rate according to Fridericia's formula (QTcF), machine or manual overread. For subject eligibility and withdrawal, QTcF will be used. For purposes of data analysis, QTcF will be used. The QTc should be based on single or averaged QTc values of triplicate electrocardiograms (ECGs) obtained over a brief recording period
• • Subject is able to understand and comply with protocol requirements and instructions
• • Subject has signed and dated informed consent
• • Women must be either of non-child bearing potential, or women with child-bearing potential and men with reproductive potential must be willing to practice acceptable methods of birth control during the study

• • Active and uncontrolled infections, including hepatitis B or C

• • Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to eltrombopag or its excipient, or azacitidine, that contraindicates the subjects' participation
• • Pregnant or lactating female
• • Any serious and/or unstable pre-existing medical condition (including any advanced malignancy other than the disease under study), psychiatric disorder, or other conditions that could interfere with subject's safety, obtaining informed consent or compliance with the study procedures
• • French subjects: the French subject has participated in any study using an investigational drug during the previous 30 days
