|---|---|---|---|
| Primary | Overall Survival | From randomization until the data cut-off date of 04 January 2016; median observation time was 11.8 months in the SOC group and 11.7 months in the blinatumomab group. | Overall survival (OS) was calculated from time of randomization until death due to any cause. Participants still alive were censored at the date they were last known to be alive. |
| Secondary | Percentage of Participants With Complete Remission Within 12 Weeks of Treatment Initiation | 12 weeks | Participants were evaluated for efficacy at the end of each treatment cycle via a central bone marrow aspiration and local peripheral blood counts. Complete Remission (CR) was defined as having ≤ 5% blasts in the bone marrow, no evidence of disease, and full recovery of peripheral blood counts: platelets \> 100,000/μl, and absolute neutrophil count (ANC) \> 1,000/μl. CR must have occurred within 12 weeks of the first dose of therapy. |
| Secondary | Percentage of Participants With Complete Remission/Complete Remission With Partial Hematological Recovery/Complete Remission With Incomplete Hematological Recovery (CR/CRh*/CRi) Within 12 Weeks of Treatment Initiation | 12 weeks | Participants were evaluated for efficacy at the end of each treatment cycle via a central bone marrow aspiration and local peripheral blood counts. Complete remission was defined as having ≤ 5% blasts in the bone marrow, no evidence of disease, and full recovery of peripheral blood counts: platelets \> 100,000/μl, and ANC \> 1,000/μl. Complete Remission with partial hematological recovery (CRh\*) was defined as ≤ 5% blasts in the bone marrow, no evidence of disease and partial recovery of peripheral blood counts: platelets \> 50,000/μl, and ANC \> 500/μl. Complete remission with incomplete hematological recovery (CRi) was defined as ≤ 5% blasts in the bone marrow, no evidence of disease and incomplete recovery of peripheral blood counts: platelets \> 100,000/μl or ANC \> 1000 (but not both). |
| Secondary | Event Free Survival (EFS) | 6 months | Event free survival was defined as the time from randomization until a documented relapse after achieving CR/CRh\*/CRi or death, whichever occurred first. Participants who failed to achieve a CR/CRh\*/CRi within 12 weeks of treatment initiation were considered as non-responders and assigned an EFS duration of 1 day. Participants still alive and relapse-free were censored on their last disease assessment date. A relapse event was any one of the following: * Hematological relapse: proportion of blasts in bone marrow \>5% or blasts in peripheral blood after documented CR or CRh\* or CRi * Progressive disease: An increase from baseline of at least 25% of bone marrow blasts or an absolute increase of at least 5,000 cells/μL in the number of circulating leukemia cells * Extramedullary relapse: extramedullary lesion that is new or increased by 50% from nadir as assessed by Cheson criteria. The Kaplan-Meier estimate of EFS at 6 months is reported. |
| Secondary | Duration of Complete Remission | Up to the data cut-off date of 04 January 2016; median observation time was 10.8 months in the SOC group and 7.0 months in the blinatumomab group. | Duration of complete remission, calculated only for participants who achieved a CR, was calculated from the date a CR was first achieved until the earliest date of a disease assessment indicating a relapse event or death, whichever occurred first. Participants who did not have a relapse event were censored on their last disease assessment date. |
| Secondary | Duration of Complete Remission/Complete Remission With Partial Hematological Recovery/Complete Remission With Incomplete Hematological Recovery (CR/CRh*/CRi) | Up to the data cut-off date of 04 January 2016; median observation time was 10.8 months in the SOC group and 7.2 months in the blinatumomab group. | Duration of CR/CRh\*/CRi, calculated only for participants who achieved a CR/CRh\*/CRi, was calculated from the date a CR/CRh\*/CRi was first achieved until the earliest date of a disease assessment indicating a relapse event or death, whichever occurred first. Participants who did not have a relapse event were censored on their last disease assessment date. |
| Secondary | Percentage of Participants With Minimal Residual Disease (MRD) Within 12 Weeks of Treatment Initiation | 12 weeks | Bone marrow samples were evaluated for MRD remission by a central laboratory. MRD remission was defined as the occurrence of an MRD level below 10\^-4 measured by quantitative reverse transcription polymerase chain reaction (PCR) or flow cytometry. |
| Secondary | Percentage of Participants Who Received an Allogeneic Hematopoietic Stem Cell Transplant (HSCT) | Up to the data cut-off date of 04 January 2016; maximum time on study was 23 months. | |
| Secondary | Number of Participants With Adverse Events | From first dose of protocol-specified therapy until 30 days after the last dose, up to the data cut-off date of 04 January 2016; median duration of treatment was 5 days in the SOC group and 70 days in the blinatumomab group. | Adverse events (AEs) were graded for severity according to the CTCAE version 4.0, where Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living. Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care activities of daily living. Grade 4: Life-threatening consequences; urgent intervention indicated. Grade 5: Death related to AE. Treatment-related adverse events (TRAEs) were those assessed by the investigator as possibly related to blinatumomab based on response to the question: Is there a reasonable possibility that the event may have been caused by blinatumomab or other protocol-specified therapies/procedures? |
| Secondary | 100-Day Mortality After Allogeneic Hematopoietic Stem Cell Transplant | 100 days, from the date of allogeneic HSCT until the data cut-off date of 04 January 2016 | The analysis of 100-day mortality after allogeneic HSCT was assessed for participants who achieved a best response of CR/CRh\*CTi within 12 weeks of treatment initiation, who received an allogeneic HSCT and did not receive any additional anticancer treatment before the transplant. 100-day mortality after allogeneic HSCT was calculated relative to the date of allogeneic HSCT. The 100-day mortality rate after allogeneic HSCT was defined as the percentage of participants having died up to 100 days after allogeneic HSCT estimated using the estimated time to death in percent calculated by Kaplan-Meier methods. Participants alive were censored on the last documented visit date or the date of the last phone contact when the patient was last known to have been alive. |
| Secondary | Number of Participants With Anti-blinatumomab Antibodies | Samples were collected on day 29 at the end of cycle 2 and 30 days after the last dose of blinatumomab (median duration of treatment was 70 days). | Anti-blinatumomab binding antibodies were evaluated using a validated electrochemiluminescence (ECL)-based assay (binding assay). Samples positive for binding were analyzed using a cell-based bioassay to determine if the detected antibodies had neutralizing properties (neutralizing assay). |
| Secondary | Time to a 10-point Decrease From Baseline in Global Health Status and Quality of Life or Death | From randomization until the data cut-off date of 04 January 2016; EORTC QLQ-C30 was assessed on day 1, 8, 15, and 29 during cycle 1; days 1, 15, and 29 in cycle 2 and each consolidation cycle, and 30-days following the last dose of drug treatment. | The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) is a 30-item questionnaire that assesses the health related quality of life of cancer patients. The EORTC QLQ-C30 consists of a global health status/quality of life (QoL) scale, 5 functional scales, 3 symptom scales, and 6 single items. The global health/QoL scale consists of 2 questions that ask participants to rate their overall health and overall quality of life durig the past week on a scale from 1 (very poor) to 7 (excellent). The scale score was derived as the sum of each score and transformed to a scale from 0 to 100 where higher scores represent a high QoL. Time to a ≥10-point decrease from baseline GHS/QoL or death, whichever came first, was calculated from baseline. Participants still alive and without a 10-point decrease in GHS/QoL EORTC QLQ-C30 were censored on their last EORTC QLQ-C30 assessment date. |
