| Primary | Hematologic Response Rate at 6 Months (Week 26) by Investigator | 6 months (Week 26) | Hematologic response rate: percentage of subjects who met any of the International Working Group criteria: Platelet count: If platelet transfusion independent at baseline (BL): Transfusion independent and increase from BL by 20×10\^9/L or more; If platelet transfusion dependent at BL: No platelet transfusion requirement for 8 weeks; Hemoglobin: If red blood cells (RBC) transfusion independent at BL: transfusion independent and increase from BL by 15 g/L or more; If RBC transfusion dependent at BL: A decrease of at least 4 units in RBC transfusions in the post-treatment 8-week period (1 unit = RBC derived from 200 mL blood) or no RBC transfusion requirement for 8 weeks; Neutrophil count: In the absence of granulocyte colony stimulating factor (G-CSF) taken within 21 days preceding the blood sample collection: Increase from BL by 0.5×10\^9/L or more, or (if \< 0.5×10\^9/L at BL) increase by 100% or more. Patients who discontinued from the trial before week 26 were treated as non-responders. |
| Secondary | Hematologic Response Rate by Investigator | Week (Wk) 13, Week 52 | Hematologic response rate: percentage of subjects who met any of the International Working Group criteria: Platelet count: If platelet transfusion independent at baseline (BL): Transfusion independent and increase from BL by 20×10\^9/L or more; If platelet transfusion dependent at BL: No platelet transfusion requirement for 8 wks; Hemoglobin: If red blood cells (RBC) transfusion independent at BL: transfusion independent and increase from BL by 15 g/L or more; If RBC transfusion dependent at BL: A decrease of at least 4 units in RBC transfusions in the post-treatment 8-week period (1 unit =RBC derived from 200 mL blood) or no RBC transfusion requirement for 8 wks; Neutrophil count: In the absence of granulocyte colony stimulating factor (G-CSF) taken within 21 days preceding the blood sample collection: Increase from BL by 0.5×10\^9/L or more, or (if \< 0.5×10\^9/L at BL) increase by 100% or more. Patients who discontinued from the trial before wks 13 \& 26 were treated as non-responders. |
| Secondary | Change From Baseline in Platelet Count | Baseline, Week 13, Week 26, Week 52 | Change (increase from baseline) in platelet count (in the absence of platelet transfusion) were calculated according to the lab test results entered into the case report form (CRF) that were summarized at each visit using descriptive statistics. Platelet Count (×109/L) was assessed in hematology test. |
| Secondary | Change From Baseline in Hemoglobin Levels | Baseline, Week 13, Week 26 and Week 52 | Change (increase from baseline) in hemoglobin (in the absence of red blood cell (RBC) transfusion) were calculated according to the lab test results entered into the CRF that were summarized at each visit using descriptive statistics. Hemoglobin level (g/L) was assessed in hematology test. |
| Secondary | Change From Baseline in Neutrophil Count | Baseline, Week 13, Week 26 and Week 52 | Change (increase from baseline) in neutrophil count (in the absence of granulocyte colony stimulating factor (G-CSF) and calculated according to the lab test results entered into the CRF that were summarized at each visit using descriptive statistics). Neutrophil count (×109/L) was assessed in hematology test. |
| Secondary | Time to Hematologic Response by Investigator | Baseline to Week 26 | Time to hematological response was defined as the time from the date of first study drug administration to the first hematological response. If a participant did not meet hematological response before or at the cutoff date, censoring was performed using the date of last assessment. |
| Secondary | Duration of Hematologic Response by Investigator | up to approx. 3.5 years | Duration of hematologic response (any response according to the response criteria for the primary endpoint). For subjects who responded, duration of response was defined as the number of weeks from the first date of hematological response until the first date of relapse or death. Only participants with at least two response assessments were included for the duration of hematologic response assessment. |
| Secondary | Frequency of Platelets Transfusion | Baseline, Week 13, Week 26 and Week 52 | For subjects receiving transfusion (platelets) at baseline, the frequency of platelet transfusion in each period (Baseline: 4 weeks before Day 1; Week 13, 26, 52: 4 weeks before each visit day) was summarized using descriptive statistics. |
| Secondary | Amount of Platelets Transfusion | Baseline, Week 13, Week 26 and Week 52 | The amount of transfusion was defined as the sum of transfusion multiplied by the volume of transfusion. |
| Secondary | Frequency of Red Blood Cells (RBC) Transfusion | Baseline, Week 13, Week 26 and Week 52 | For subjects receiving transfusion (RBC (Red Blood Cell)) at baseline, the frequency of RBC transfusion in each period (Baseline: 8 weeks before Day 1; Week 13, 26, 52: 8 weeks before each visit day) was summarized using descriptive statistics. |
| Secondary | Amount of Red Blood Cells (RBC) Transfusion | Baseline, Week 13, Week 26 and Week 52 | The amount of RBC transfusion was defined as the sum of transfusion multiplied by the volume of transfusion. |
| Secondary | Plasma PK Parameters of Eltrombopag: Cmax | pre-dose, and 1, 2, 4, 6, 8 and 24 hours post-dose on Day 14 | Cmax is the maximum (peak) observed plasma drug concentration after single dose administration (mass\*volume-1). Blood samples were collected from patients to assess the plasma concentrations of eltrombopag. The plasma concentrations were used to determine the PK characteristics of eltrombopag. Serial intensive PK blood samples were collected for the initial 25 mg/day dose to provide at least 12 participants with evaluable PK profiles at steady state. |
| Secondary | Plasma PK Parameters of Eltrombopag: Tmax | pre-dose, and 1, 2, 4, 6, 8 and 24 hours post-dose on Day 14 | Tmax is the time to reach maximum (peak) plasma drug concentration after single dose administration (time). Blood samples were collected from all patients to assess the plasma concentrations of eltrombopag. The plasma concentrations were used to determine the PK characteristics of eltrombopag. Serial intensive PK blood samples were collected for the initial 25 mg/day dose to provide at least 12 participants with evaluable PK profiles at steady state. |
| Secondary | Plasma PK Parameters of Eltrombopag: AUCtau & AUClast | pre-dose, and 1, 2, 4, 6, 8 and 24 hours post-dose on Day 14 | AUCtau is the area under the curve calculated to the end of a dosing interval (tau) at steady-state (amount\*time\*volume-1). AUClast is the AUC calculated from time 0 to the time of the last quantifiable concentration. Blood samples were collected from patients to assess the plasma concentrations of eltrombopag. The plasma concentrations were used to determine the PK characteristics of eltrombopag. Serial intensive PK blood samples were collected for the initial 25 mg/day dose to provide at least 12 participants with evaluable PK profiles at steady state. |
| Secondary | Plasma PK Parameters of Eltrombopag: CLss/F | pre-dose, and 1, 2, 4, 6, 8 and 24 hours post-dose on Day 14 | Steady State (CLss/F) is the apparent systemic (or total body) clearance at steady state from plasma (volume/time) following drug administration. Blood samples were collected from patients to assess the plasma concentrations of eltrombopag. The plasma concentrations were used to determine the PK characteristics of eltrombopag. Serial intensive PK blood samples were collected for the initial 25 mg/day dose to provide at least 12 participants with evaluable PK profiles at steady state. |
| Secondary | Plasma Trough Concentration of Eltrombopag | Pre-dose sample on the 15th day after each new dose level was started | Ctrough is the pre-dose concentration at the end of dose interval (mass\*volume-1). Blood samples were collected from patients to assess the plasma concentrations of eltrombopag. The plasma concentrations were used to determine the PK characteristics of eltrombopag. Serial intensive PK blood samples were collected for the initial 25 mg/day dose to provide at least 12 participants with evaluable PK profiles at steady state. Sparse PK blood samples were collected for the other doses and in the rest of the patients for Ctrough assessment. |
| Secondary | Number of Participants With Clonal Evolution | From Baseline up to approx. 2.9 years | Number of participants with clonal evolution with a normal karyotype at baseline including clonal evolution to PNH (Paroxysmal Nocturnal Hemoglobinuria), evolution to AML (Acute Myeloid Leukemia) or MDS (Myelodysplastic Syndromes). |
