A Study of Eltrombopag or Placebo in Combination With Azacitidine in Subjects With International Prognostic Scoring System (IPSS) Intermediate-1, Intermediate-2 or High-risk Myelodysplastic Syndromes (MDS)
Stopped early · Phase 3 · Has a placebo group
Conditions studied: Thrombocytopaenia
In brief
Eltrombopag olamine (SB-497115-GR) is an orally bioavailable, small molecule thrombopoietin receptor agonist that may be beneficial in medical disorders associated with thrombocytopenia. Eltrombopag has been shown to increase platelet counts in patients with thrombocytopenia from various etiologies (Idiopathic thrombocytopenic purpura \[ITP\], liver disease, aplastic anemia and chemotherapy induced thrombocytopenia). Approximately 350 subjects will be randomized in a 1:1 ratio (175 into the eltrombopag arm and 175 into the placebo arm). Approximately 55 subjects will be enrolled into the azacitidine. Subjects with intermediate-1, intermediate-2 or high risk MDS by IPSS, and baseline platelet count of \<75 Giga (10\^9) per liter (Gi/L) will only be enrolled. This is a randomized, double-blind, parallel group, placebo-controlled study designed to explore the platelet supportive care effects of eltrombopag versus placebo in combination with the standard of care hypomethylating agent, azacitidine. The primary objective of this study is to determine the effect of eltrombopag versus placebo on the proportion of subjects who are platelet transfusion free during the first 4 cycles of azacitidine therapy. Key secondary endpoints include overall survival, disease response, and disease progression.

Who can join
Age: 18 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Age >=18 years (For subjects in Taiwan, Age >= 20 years)
- 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
- Women of childbearing potential must have a negative serum or urine pregnancy test within 7 days of first dose of study treatment and agree to use effective contraception during the study and for 3 months following the last dose of study treatment
- Men with a female partner of childbearing potential must have either had a prior vasectomy or agree to use effective contraception from time of randomization until 16 weeks after the last dose of study treatment
- French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category
You may not qualify if…
- Previous treatment with hypomethylating agent or induction chemotherapy for MDS
- Proliferative type chronic myelomonocytic leukemia with white blood cell count >12 Gi/L at any time during the 28 days before Day 1
- History of treatment with eltrombopag, romiplostim or other thrombopoietin receptor (TPO-R) agonists
- Previous allogeneic stem-cell transplantation
- Known thrombophilic risk factors. Exception: Subjects for whom the potential benefits of participating in the study outweigh the potential risks of thromboembolic events, as determined by the investigator
- Treatment with an investigational drug within 30 days or 5 half-lives (whichever is longer) preceding the first dose of investigational product (eltrombopag/placebo)
- Active and uncontrolled infections, including hepatitis B or C
- Human Immunodeficiency Virus (HIV) infection
- 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
