Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Maximum Tolerated Dose (MTD) of 2 Schedules of BI 811283 in Combination With Cytarabine.	The MTD was defined as the highest dose at which 6 patients were treated and less than 2 patients who experienced a dose limiting toxicities (DLT) within the first cycle of treatment.The MTD was defined based on safety data from the first cycle only.; It was determined using a standard "3 + 3 design with de-escalation".	up to 28 days of treatment	No
Secondary	Response (Complete Remission [CR], Complete Remission With Incomplete Blood Count Recovery [CRi])	Response to treatment was evaluated according to the following criteria (modified from the National Cancer Institute/Cancer and Leukemia Group B criteria: The best overall response was defined as the best overall response recorded during the time period from the start of the treatment until the end of the treatment period, progression or death (whichever was earlier). Possible categories for best overall response were CR, CRi, Partial remission (PR), no change (NC), Progressive disease (PD) and no assessment.; Complete remission (CR): morphologically leukaemia free state (i.e. bone marrow with < 5% blasts by morphologic criteria and no Auer rods, no evidence of extramedullary leukaemia) and absolute neutrophil count = 1,000/µL and platelets > 100,000/µL.; Complete remission with incomplete blood count recovery ("incomplete" CR, CRi).All of the above criteria for CR had to be met, except that neutrophils < 1,000/µL or platelets < 100,000/µL in the blood.	Data collected up to cut-off date 20Oct2011, Up to 1239 days	No

Data from first treatment administration until cut-off date of 20 October 2011; up to 1239 days	No
Secondary	Incidence of Dose Limiting Toxicity (DLT)	Number of participants with DLT in the first cycle (28 days) for the determination of the maximum tolerated dose (MTD)	up to 28 days of treatment	No
Secondary	Partial Remission	Response to treatment was evaluated according to the following criteria (modified from the National Cancer Institute/Cancer and Leukemia Group B criteria; The best overall response was defined as the best overall response recorded during the time period from the start of the treatment until the end of the treatment period, progression or death (whichever was earlier). Possible categories for best overall response were CR, CRi, Partial remission (PR), no change (NC), Progressive disease (PD) and no assessment.; Partial remission (PR). All of the criteria for CR had to be met, except that the bone marrow had to contain = 5% but less than 25% blasts (or = 50% of initial blast count), or < 5% blasts in the presence of Auer rods or abnormal morphology.	Data collected up to cut-off date 20 Oct 2011, Up to 1239 days	No
Secondary	Event Free Survival (EFS)	EFS was defined as the duration of time from randomisation to time of treatment failure (i.e. PD), relapse from CR, or death from any cause, whichever came first.	Data collected up to cut-off date 20 Oct 2011, Up to 1239 days	No
Secondary	Relapse Free Survival	Relapse-free survival was defined only for patients who achieved CR/CRi and was measured from the date of attaining CR/CRi until the date of recurrence or death from any cause, whichever occurred first.; Number of patients having relapse free survival are presented.	Data collected up to cut-off date 20 Oct 2011, Up to 1239 days	No
Secondary	Remission Duration	Remission duration analysis was defined only for patients who achieved CR, and was measured from the date of attaining CR until the date of disease recurrence (relapse). For patients who died without report of relapse, remission duration was censored on the date of death, regardless of the cause.	Data collected up to cut-off date 20 Oct 2011, Up to 1239 days	No
Secondary	Overall Survival (OS)	OS was defined for all patients that entered the trial, and measured from the date of randomization until death from any cause.	Data collected up to cut-off date 20 Oct 2011, Up to 1239 days	No
