Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants In Best Hematological Response Categories as Determined by the Investigator Using International Working Group 2000 (IWG 2000) Criteria For Myelodysplastic Syndromes (MDS) During the Initial Study Period. [ Time Frame: Day 1 (randomization) to 6 months ]

    Participant counts by best hematological response; complete remission(CR) is better than a partial remission(PR) which is better than stable disease(SD).

    Investigator determined responses followed IWG 2000 criteria for MDS CR: repeat bone marrow show <5% myeloblasts, and peripheral blood evaluations lasting >=2 months of hemoglobin(>110 g/L), neutrophils(>=1.5x10^9/L), platelets(>=100x10^9/L), blasts (0%) and no dysplasia PR is the same as CR for peripheral blood: bone marrow shows blasts decrease by >=50% or a less advanced FAB classification from pretreatment (see Population Descrip)


  2. Number of Participants With Best Hematological Improvement Derived Using International Working Group 2000 (IWG 2000) Criteria for MDS During the Initial Study Period. [ Time Frame: Day 1 (randomization) to 6 months ]

    IWG 2000 Criteria: Pretreatment=hemoglobin <110g/L or RBC transfusion-dependence, platelet count <100x10^9/L or platelet transfusion dependence, absolute neutrophil count <1.5x10^9/L.

    Erythroid response: Major->20g/L increase in hemoglobin or transfusion independence. Minor- 10-20g/L increase in hemoglobin or >=50% decrease in transfusion requirements.

    Platelet response: Major-absolute increase of platelet count by >=30x10^9/L or platelet transfusion independence. Minor->=50% increase in platelet count with net increase >10x10^9/L but <30x10^9/L.

    (continued in Population Description)


  3. Number of Participants With Overall Best Hematologic Response and Hematologic Improvement Based on IWG 2000 Criteria For MDS During the Initial Study Period [ Time Frame: Day 1 (randomization) to 6 months ]
    Number of participants whose best hematological outcome was either complete remission (CR), partial remission (PR) (as determined by the investigator), or any hematologic improvement (based on the IWG 2000 criteria for MDS). See previous outcomes for detailed definitions.

  4. Number of Participants Who Improved or Maintained The Hematologic Response From the Initial Study Period (Based on IWG 2000 Criteria For MDS) During the Maintenance Period [ Time Frame: 24 months ]
    Hematologic response during the maintenance period are compared to the response in the initial study period. Initial response could have been a complete remission, a partial remission, stable disease or a hematologic improvement. Maintenance period best response is after randomization to a maintenance arm for those randomized, and is after the start of cycle 7 for those remaining on initial period treatment throughout the study.


Secondary Outcome Measures :
  1. Baseline Hemoglobin Values [ Time Frame: Day 1 (randomization) ]
    The median values for hemoglobin based on blood tests performed on study day 1 (prior to study treatment) constitute a baseline measure for hemoglobin. Baseline values are used to compare to values following treatment.

  2. Change From Baseline in Hemoglobin at End of Initial Study Period (6 Months) [ Time Frame: 6 months ]
    The difference between hemoglobin values at the end of the initial study period minus the hemoglobin values at baseline.

  3. Change From Baseline in Hemoglobin at the End of the Maintenance Study Period [ Time Frame: 24 months ]
    The difference between hemoglobin values at the end of the maintenance study period minus the hemoglobin values at baseline.

  4. Baseline Platelet Values [ Time Frame: Day 1 (randomization) ]
    The median values for platelets based on blood tests performed on study day 1 (prior to study treatment) constitute a baseline measure for platelets. Baseline values are used to compare to values following treatment.

  5. Change From Baseline in Platelets at the End of Initial Study Period (6 Months) [ Time Frame: 6 months ]
    The difference between platelet values at the end of the initial study period minus the platelet values at baseline.

  6. Change From Baseline in Platelets at the End of the Maintenance Study Period (Month 24) [ Time Frame: 24 months ]
    The difference between platelet values at the end of the maintenance study period minus the platelet values at baseline.

  7. Baseline Absolute Neutrophil Count (ANC) Values [ Time Frame: Day 1 (randomization) ]
    The median values for ANC based on blood tests performed on study day 1 (prior to study treatment) constitute a baseline measure for ANC. Baseline values are used to compare to values following treatment.

  8. Change From Baseline in Absolute Neutrophil Count (ANC) at the End of Initial Study Period (6 Months) [ Time Frame: 6 months ]
    The difference between ANC values at the end of the initial study period minus the ANC values at baseline.

  9. Change From Baseline in Absolute Neutrophil Count (ANC) at the End of the Maintenance Study Period (Month 24) [ Time Frame: 24 months ]
    The difference between ANC values at the end of the maintenance study period minus the ANC values at baseline.

  10. Red Blood Cell (RBC) Transfusion Status at Baseline and End of Initial Study Period (6 Months) [ Time Frame: 6 months ]
    Shift table comparing the RBC transfusion status of patients at the end of the initial study period to the transfusion status at baseline.

  11. Platelet Transfusion Status at Baseline and End of Initial Study Period (6 Months) [ Time Frame: 6 months ]
    Shift table comparing the platelet transfusion status of patients at the end of the initial study period to the transfusion status at baseline.

  12. Red Blood Cell (RBC) Transfusion Status at Baseline and End of Maintenance Study Period (24 Months) [ Time Frame: 24 months ]
    Shift table comparing the RBC transfusion status of patients at the end of the maintenance study period to the transfusion status at baseline.

  13. Platelet Transfusion Status at Baseline and End of Maintenance Study Period (24 Months) [ Time Frame: 24 months ]
    Shift table comparing the platelet transfusion status of patients at the end of the maintenance study period to the transfusion status at baseline.

  14. Change From Baseline in the Number of Infections Requiring Treatment With IV Antibiotics Per Treatment Cycle (28 Days) for the Initial Study Period [ Time Frame: 6 months ]
    Baseline uses the average number of infections requiring IV antibiotic treatment from the 28 days prior to and including the day of first dose to an initial treatment arm. Initial study period values total the number of infections requiring IV antibiotic treatment divided by the number of treatment cycles (each cycle is approximately one month).

  15. Change From Baseline in the Number of Infections Requiring Treatment With IV Antibiotics Per Treatment Cycle (28 Days) for the Maintenance Study Period [ Time Frame: 24 months ]
    Baseline uses the average number of infections requiring IV antibiotic treatment from the 28 days prior to and including the day of first dose to an initial treatment arm. Maintenance study period values total the number of infections requiring IV antibiotic treatment divided by the number of treatment cycles (each cycle is approximately one month).
