Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Patients With Overall Complete Response for Stage I | IWG Cheson criteria every 28 days from randomization for study duration (24 months, between 2009 - 2011) | Percentage of patients achieving either a complete response (CR) or a confirmed complete remission with incomplete recovery of neutrophils or platelets (confirmed CRi). Per Cheson Criteria: Confirmed complete remission (CRi) is defined as a disappearance of blasts in the peripheral blood; a decrease in bone marrow blasts to \<5% total bone marrow nucleated cells demonstrated in bone marrow aspirate; absence of Auer rods; no persistent extramedullary leukaemia. Complete response (CR) is defined as all requirements to meet CRi and in addition: recovery of neutrophils to ≥1.0 x 109/L and platelets to ≥100 x 109/L; transfusion-independence. |

| Duration of Response (DoR): Stage I and Transition Phase | DoR was measured every 28 days from randomization for study duration (24 months, between 2009 - 2011) | DoR was defined for the median of days which showed a confirmed CRi or CR, as the time from first documented evidence of CRi or CR until the first documented sign of disease progression or death. Duration of Response was measured from the Response Start date until evidence of patient relapse or death. Stage I : 45 patients randomized in a 2:1 ratio to AZD1152 or LDAC. Transition phase: enrollment of up to 30 additional patients randomized as per stage I. |
| Percent of Patients With Worsened Trial Outcome Index (TOI) | TOI was measured every 28 days from randomization for study duration (24 months, between 2009 - 2011) | TOI is derived from the sum of the Functional Well Being (FWB), Physical Well Being (PWB) and additional subscales of the FACT-Leu. The TOI subscale consists of 31 items with TOI scores ranging from 0 to 124. The TOI is described as a summary measure of HRQoL. Higher scores indicate better HRQoL. Negative changes from baseline indicate a worsening of HRQoL while positive changes indicate an improvement in HRQoL. A response of Worsened was a change from baseline in score of less than or equal to -9. |
| Percent of Patients With Worsened Functional Assessment of Cancer Therapy - Leukaemia (FACT-Leu) Score. | FACT-Leu was measured every 28 days from randomization for study duration (24 months, between 2009 - 2011) | The total FACT-Leu score consists of 44 items with total scores ranging from 0 to 176. Higher scores indicate better HRQoL. Negative changes from baseline indicate a worsening of HRQoL while positive changes indicate an improvement in HRQoL. A response of Worsened was a change from baseline in score of less than or equal to -11. |
| Overall Survival (OS) | Assessed from randomisation until the date of death from any cause, assessed up to 24 months | Overall Survival is defined as the median time from randomisation to death from any cause. Patients who were not known to have died at the time of the analysis were censored at the date they were last known to be alive. |
