Detailed Description
This is a randomized, double-blind, placebo-controlled, Japanese local phase II study to evaluate the efficacy and safety of eltrombopag monotherapy in Japanese adult patients with platelet transfusion-dependent lower-risk MDS (IPSS-R very low, low, intermediate risk with bone marrow blast count < 5% and cytogenetic very good, good or intermediate risk). Platelet transfusion dependence at baseline is defined as receiving platelet transfusion regularly with a frequency of 2 or more times within 4 weeks prior to randomization. Platelet transfusion should be performed for a patient with platelet counts < 20 X 10^9/L, or with hemorrhagic symptoms and platelet counts < 30 X 10^9/L.
The primary objective is to demonstrate superiority of eltrombopag versus placebo in terms of the proportion of participants who achieve platelet transfusion independence at Week 24.

Cytogenetic very good, good or intermediate risk corresponding to IPSS-R
- Platelet transfusion dependence
- Refractory, intolerant to, or ineligible for MDS treatments

Exclusion Criteria:
- Patients with a history of prior administration of eltrombopag, romiplostim, or other TPO-RA
- Therapy-related MDS per WHO classification revised 4th edition

- MDS with excess blasts (EB) per WHO classification revised 4th edition
- Known history of IPSS-R high or very high risk MDS
- Currently receiving treatments for MDS (e.g., HMA, cyclosporine A (CsA) or lenalidomide). Supportive treatment with erythropoiesis-stimulating agents (ESAs) in anemic patients or granulocyte-colony stimulating factor (G-CSF) in patients with severe neutropenia and recurrent infections is allowed if at stable dosage for 3 months prior to screening and continued at the same dosing/schedule until the optimal dose of eltrombopag has been established.

- Bone marrow fibrosis that leads to an inability to aspirate adequate bone marrow sample
- Known thrombophilic risk factors (except in cases where potential benefits of participating in the study outweighed potential risks of thromboembolic events(TEE), as determined by the investigator)
Other protocol-defined inclusion/exclusion criteria may apply.

|
The changes from baseline to each visit where measured using QLQ-C30. EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Subject's responses to 28 questions about their physical functioning, disease symptoms, global health status and utilities are scored on a 4-point scale (1=Not at all to 4=Very much), a low score indicates a high / healthy level of functioning. And the responses to 2 questions about health-related QoL are scored on a 7-point scale (1=Very poor to 7=Excellent), a high score indicates a high / healthy level of functioning. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. |
Baseline, every 4 weeks until week 52, every 8 weeks after week 52 up to end of treatment or end of post-treatment follow-up, approximately 3.5 years.
