Brief Summary:

Myelodysplastic syndromes (MDS) prevail in older age and are characterized by ineffective erythropoiesis and peripheral cytopenias. Supportive therapy is the main therapeutic option for most patients. Quality of Life (QoL) is mainly deteriorated by anemia and by the limitations associated with thrombocytopenia, neutropenia and transfusion dependence. The only available treatment for severe thrombocytopenia, in the presence of bleeding, is platelet transfusion.

Eltrombopag is an orally bioavailable agonist of the thrombopoietin receptor. In adult patients with chronic immune thrombocytopenia (ITP), Eltrombopag rapidly increases platelet counts and significantly reduces bleeding episodes during treatment. Eltrombopag is well tolerated. In 2007, Eltrombopag has received the Orphan Drug Designation for the treatment of ITP (EMEA/OD/031/07), and in 2008 the Food and Drug Association approved Eltrombopag for the treatment of ITP refractory or resistant. It has been shown that in patients affected by MDS and by acute myeloid leukemia, Eltrombopag neither increases the proliferation, nor the clonogenic growth capacity of bone marrow blasts. Furthermore, Eltrombopag induces an increase in the megakaryocytic differentiation and in the formation of normal megakaryocytic colonies. These results provide the rationale for pursuing further research on Eltrombopag for the treatment of thrombocytopenia in case of MDS.

The study is open to adult patients with myelodysplastic syndrome (MDS) with thrombocytopenia and low- or intermediate-1 IPSS risk (Index Prognostic Score System).

Severe thrombocytopenia associated with MDS may lead to death from hemorrhage, even in low prognostic risk patients. The benefit of platelet transfusion is short-termed. Patients become refractory in the long term. The availability of a treatment that induces the increase of platelet count is extremely important, either in terms of quality of life, and in overall survival.

Drug Information available for: Eltrombopag

Arm Intervention/treatment
Experimental: Arm 1 (Eltrombopag)
Arm 1 is the active treatment arm
Drug: Eltrombopag/Revolade
Eltrombopag 50 mg once daily has been selected as the starting dose for this study. Thereafter, dependent on platelet response the dose of study medication can be increased by 50 mg every 2 weeks, up to a maximum dose of 300 mg once daily (150 mg in subjects of East Asian ethnicity).

Placebo Comparator: Arm 2 (Placebo)
Arm 2 is the control arm
Other: Placebo
The administration is the same of eltrombopag




Primary Outcome Measures :

Secondary Outcome Measures :
  1. Quality of life (QoL) score [ Time Frame: six months ]
    to evaluate the changes of the quality of life in the two arms

  2. number of monthly platelet transfusions [ Time Frame: six months ]
  3. duration of transfusion independence [ Time Frame: six months ]
  4. time to response [ Time Frame: six months ]
    time to response (time from starting treatment to time of achievement of CR or PR)

  5. incidence and severity of bleeding [ Time Frame: six months ]
    incidence and severity of bleeding using the WHO (World Health Organization)Bleeding Scale

  6. overall survival [ Time Frame: 2 and 5 years ]
    overall survival (OS) at 2 and at 5 years

  7. leukemia-free survival (LFS) [ Time Frame: 2 and 5 years ]
    leukemia-free survival (LFS) at 2 and at 5 years (events for LFS are defined as death and progression to AML);

Criteria

Inclusion Criteria:
