Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Blinatumomab

Arm Description

Participants received blinatumomab by continuous intravenous (CIV) infusion over 4 weeks followed by a treatment-free interval of 2 weeks for up to 5 consecutive cycles. The initial dose was 9 μg/day for the first seven days of treatment, escalated to 28 μg/day starting from Week 2 of treatment.

Outcomes

Primary Outcome Measures

Percentage of Participants With a Best Response of Complete Remission or Complete Remission With Only Partial Hematological Recovery Within 2 Cycles of Treatment
Hematological assessments were performed from bone marrow biopsy samples. All hematological assessments of bone marrow were reviewed in a central reference laboratory. Hematological remissions were defined by the following criteria: Complete Remission (CR): bone marrow blasts ≤ 5% no evidence of disease full recovery of peripheral blood counts: platelets > 100,000/μL, and absolute neutrophil count (ANC) > 1,000/μL Complete Remission With Partial Hematological Recovery (CRh*): bone marrow blasts ≤ 5% no evidence of disease partial recovery of peripheral blood counts: platelets > 50,000/μL, and ANC > 500/μL.

Secondary Outcome Measures

Time to Hematological Relapse (Duration of Response)
Time to hematological relapse was measured for participants in remission during the core study (the time from the first infusion through 30 days after the last infusion), from the time the participant first achieved remission until first documented relapse or death due to disease progression. Participants without documented relapse (hematological or extramedullary) and who did not die were censored at the time of their last bone marrow assessment or their last survival follow-up visit confirming remission. Participants who died without having reported hematological relapse or without showing any clinical sign of disease progression were censored on their date of death. Hematological relapse is defined as: proportion of blasts in bone marrow > 5% after documented CR/CRh* or blasts in peripheral blood after documented CR/CRh*. Time to hematological relapse was analyzed by Kaplan-Meier methods and the median observation time was calculated by the reverse Kaplan Meier method.
Percentage of Participants Who Received an Allogeneic Hematopoietic Stem Cell Transplant (HSCT) During Blinatumomab Induced Remission
Participants who were eligible for allogeneic HSCT were those who achieved remission (complete response or complete response with partial recovery of peripheral blood counts) after 2 cycles of blinatumomab treatment, and no further anti-leukemic medication was given before HSCT.
Percentage of Participants With a Best Response of Complete Remission Within 2 Cycles of Treatment
Complete Remission was defined by the following criteria: bone marrow blasts ≤ 5% no evidence of disease full recovery of peripheral blood counts: platelets > 100,000/μL, and absolute neutrophil count (ANC) > 1,000/μL
Percentage of Participants With a Best Response of Complete Remission With Only Partial Hematological Recovery Within 2 Cycles of Treatment
Complete Remission With Partial Hematological Recovery was defined by the following criteria: bone marrow blasts ≤ 5% no evidence of disease partial recovery of peripheral blood counts: platelets > 50,000/μL, and ANC > 500/μL.
Percentage of Participants With a Best Response of Partial Remission Within 2 Cycles of Treatment
Partial Remission is defined as bone marrow blasts 6% to 25% with at least a 50% reduction from baseline.
Relapse-free Survival
Relapse-free survival was assessed for participants who achieved a complete remission or complete remission with partial hematological recovery during the core study and was measured from the time the participant first achieved remission until first documented relapse or death due to any cause. Participants without a documented relapse (hematological or extramedullary) or who did not die were censored at the time of their last bone marrow assessment or their last survival follow-up visit confirming remission. Relapse free survival was estimated using Kaplan-Meier methods and the median observation time was calculated by the reverse Kaplan Meier method.
Event-free Survival
Event-free survival was calculated from the start date of blinatumomab infusion until the date of bone marrow aspiration at which hematological relapse was first detected, or the date of diagnosis on which the hematological or extramedullary relapse was documented or the date of start of any new therapy for ALL (excluding HSCT), or the date of death, whichever was earlier. Participants who did not achieve complete remission or complete remission with partial hematological recovery during the core study were evaluated as having an event on Day 1. Participants in remission who did not experience hematological relapse, did not receive a new therapy for ALL (excluding HSCT), and did not die were censored on the date of the last available bone marrow aspiration or on the last date of survival follow-up visit, whichever was later. Event free survival was estimated using Kaplan-Meier methods and the median observation time was calculated by the reverse Kaplan Meier method.
Overall Survival
Overall survival was measured for all participants from the time the participant received the first treatment of blinatumomab until death due to any cause or the date of the last follow-up. Participants who did not die 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. Overall survival was estimated using Kaplan-Meier methods. The median follow-up time with respect to overall survival was calculated by the reverse Kaplan Meier method.
Number of Participants With Treatment-emergent Adverse Events
Adverse events (AEs) were evaluated for severity according to the the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4, as follows: Grade 1 - Mild AE; Grade 2 - Moderate AE; Grade 3 - Severe AE; Grade 4 - Life-threatening or disabling AE; Grade 5 - Death. The investigator used medical judgment to determine if there was a causal relationship (ie, related, unrelated) between an adverse event and blinatumomab. An AE was considered "serious" if it resulted in death, was life-threatening, requires or prolongs inpatient hospitalization, results in persistent or significant incapacity or substantial disruption to conduct normal life functions, is a congenital anomaly or birth defect or is a medically important condition. Progressive disease was not an adverse event, per the protocol, unless it was more severe than expected for the patient. Therefore, many deaths due to progressive disease were not counted as adverse events.
100-Day Mortality After Allogeneic Hematopoietic Stem Cell Transplant
The analysis of 100-day mortality after allogeneic HSCT was assessed for all participants who received an allogeneic HSCT while in remission (CR/CRh*) following treatment with blinatumomab. 100-day mortality after allogeneic HSCT was calculated relative to the date of allogeneic HSCT. Patients 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. The 100-day mortality rate after allogeneic HSCT was defined as the percentage of patients having died up to 100 days after allogeneic HSCT estimated using the estimated time to death in percent calculated by Kaplan-Meier methods.
Serum Blinatumomab Concentration at Steady State
The steady state concentration of blinatumomab was summarized as the observed concentrations collected at least 10 hours after the start of the IV infusion or dose step for cycle 1 and cycle 2, respectively. Serum concentrations of blinatumomab were measured using a validated bioassay. The lower limit of quantitation (LLOQ) = 50.0 pg/mL.
Serum Cytokine Peak Levels
The activation of immune effector cells was monitored by the measurement of peripheral blood cytokine levels including interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF)-α and interferon gamma (IFN)-γ using enzyme-linked immunosorbent assays or cytometric bead assays. The limit of detection of the assay (LOD) was 20 pg/mL and the limit of quantification (LOQ) was 125 pg/mL. Data below LOD were set to 10 pg/mL while data < LOQ and > LOD were reported as measured. Serum IL-4 levels were below detection limit (< 20 pg/mL) at all time points in all participants studied.
Percentage of Participants With a Best Response of Blast Free Hypoplastic or Aplastic Bone Marrow Within 2 Cycles of Treatment
Blast Free Hypoplastic or Aplastic Bone Marrow was defined as: bone marrow blasts ≤ 5% no evidence of disease insufficient recovery of peripheral counts: platelets ≤ 50,000/μL and/or absolute neutrophil count (ANC) ≤ 500/μL
Best Response During the Core Study
Complete Remission (CR): bone marrow blasts ≤ 5% no evidence of disease full recovery of peripheral blood counts: platelets > 100,000/μL, and absolute neutrophil count (ANC) > 1,000/μL Complete Remission With Partial Hematological Recovery (CRh*): bone marrow blasts ≤ 5% no evidence of disease partial recovery of peripheral blood counts: platelets > 50,000/μL, and ANC > 500/μL Blast Free Hypoplastic or Aplastic Bone Marrow: bone marrow blasts ≤ 5% no evidence of disease insufficient recovery of peripheral counts: platelets ≤ 50,000/μL and/or ANC ≤ 500/μL Partial Remission: • bone marrow blasts 6% to 25% with at least a 50% reduction from Baseline.

5. Study Description

Brief Summary
The purpose of this study is to confirm whether the bispecific T cell engager antibody blinatumomab (MT103) is effective and safe in the treatment of patients with relapsed or refractory Acute Lymphoblastic Leukemia (ALL).
Detailed Description
Relapsed/refractory B-precursor ALL in adult patients is an aggressive malignant disease with dismal prognosis. Several studies have reported long term survival to be below 10%. Major prognostic factors are duration of first complete remission (CR1) and age. With current salvage chemotherapy, complete remission (CR) rate is low (20 to 30%) in patients in first salvage with short duration (< one year) of first remission, patients relapsed after first salvage, or patients aged 60 years and older. Duration of CR is usually very short (median disease free survival [DFS]: 2.0-7.5 months). Allogeneic hematopoietic stem cell transplantation (HSCT) may provide a curative treatment option for patients in CR with a satisfactory donor and appropriate clinical status including age, organ function, and remission status. Allogeneic HSCT is not an option in most elderly patients with relapsed ALL. Additional therapeutic approaches are urgently needed. Blinatumomab is a bispecific single-chain antibody derivative against CD (cluster of differentiation)19 and CD3, designed to link B cells and T cells resulting in T cell activation and a cytotoxic T cell response against CD19-expressing cells. In vitro data indicate CD19+ lymphoma and leukemia cell lines to be extremely sensitive to blinatumomab-mediated cytotoxicity. Blinatumomab has the potential to provide meaningful therapeutic benefits to patients compared with existing treatments for this patient population. This study consists of a screening period, a treatment period and a follow-up period. Participants receive one to five treatment cycles of blinatumomab at a target dose of 28 μg/day. In the first cycle, the initial dose is 9 μg/day for the first seven days of treatment, escalated to 28 μg/day starting from Week 2 of treatment. Participants who achieve remission within two cycles of treatment can receive up to three additional cycles of consolidation treatment or proceed to allogeneic HSCT. In the event of progression or relapse within the treatment period, treatment will be terminated. Participants with hematological relapse during the efficacy or safety follow-up period may receive up to three additional cycles of blinatumomab (retreatment) for a maximal total of eight cycles at the investigator´s discretion. Thirty days after end of the last treatment, participants have an end-of-core-study visit. Following this, there are efficacy follow-up visits at 3, 6, 9, 12, 18 and 24 months at the most after treatment start. Once efficacy follow-up is complete, information on survival collected at least every six months until death or at least until three years after treatment start, whichever occurs earlier (survival follow-up).
