Detailed Description

This is a phase 2/3 open label, multicenter trial testing blinatumomab monotherapy for the treatment of subjects with R/R aggressive B-NHL not achieving CMR after standard platinum-based chemotherapy regimens administered as S1. This study incorporates multiple interim analyses for futility, efficacy, and unblinded sample-size re-estimation. In the phase 3 part of the study, blinatumomab will be compared to IC chemotherapy.The phase 2 component of the study will consist of up to a 28-day screening period, approximately 70 to 112 days of study treatment, a 30-day (+/- 3days) safety follow up, and long-term follow up that will conclude with the final analysis of the phase 3 component, estimated at 30 months after initiation of the phase 3 component. For the phase 3 component, the study will consist of up to a 28-day screening period, a treatment period of up to approximately 168 days, a 30-day safety follow-up visit, and long-term follow up. Long-term follow up will conclude with the final analysis.In the phase 2 component, enrolled subjects will receive blinatumomab monotherapy. In the phase 3 component, enrolled subjects will be randomized in a 1:1 ratio to blinatumomab or IC chemotherapy.

In March 2019, decision made to not proceed with phase 3.

  • Outcome Measures

    Primary Outcome Measures

    1. Phase 2: Percentage of Participants Who Achieved Complete Metabolic Response (CMR) [Up to 12 weeks after first dose of blinatumomab]

      Complete metabolic response (CMR) was determined by central radiographic assessment of positron emission tomography and computed tomography (PET/CT) scans using the Lugano Classification.

    2. Phase 3: Number of Participants Who Achieved Complete Metabolic Response (CMR) [Up to 12 weeks after first dose of study treatment]

      Complete metabolic response (CMR) was determined by central radiographic assessment of positron emission tomography and computed tomography (PET/CT) scans using the Lugano Classification.

    Secondary Outcome Measures

    1. Phase 2: Overall Survival (OS) [From randomization until the end of study, up to 30 months]

      OS was defined as the time from the date of randomization until death due to any cause. OS was calculated using Kaplan-Meier estimates.

    2. Phase 2: Objective Response Rate (ORR) [Up to 12 weeks after first dose of blinatumomab]

      ORR is inclusive of all participants who achieved CMR or those who achieved partial metabolic response (PMR), as determined by central radiographic assessment of PET/CT scans using the Lugano Classification.

    3. Phase 2: Progression Free Survival (PFS) [From first dose of blinatumomab until the end of study, up to 30 months]

      PFS was defined as the time from start of treatment with blinatumomab until the date of diagnosis of progression of lymphoma, or date of death, whichever is earliest. PFS was estimated using Kaplan-Meier method.

    4. Phase 2: Duration of Response (DOR) [From first dose of blinatumomab up to 12 weeks]

      DOR was calculated only for participants who achieve a response (CMR or PMR). The duration was calculated from the date a response, CMR or PMR, was first achieved until the earliest date of a disease assessment indicating disease progression or death, whichever occured first. DOR was estimated using Kaplan-Meier method.

    5. Phase 2: Percentage of Participants Who Experienced Successful Mobilization [From first dose of blinatumomab until the end of study, up to 30 months]

      Successful mobilization rate was defined as the percentage of participants who initiated mobilization while in remission and without any other anti-tumor therapy where the mobilization procedure had an outcome of 'Successful'. Successful mobilization was dictated by institutional standards and defined when the target cell dose was no less than 2 x 10^6 CD34+ cells/kg.

    6. Phase 2: Percentage of Participants Who Had Allogeneic or Autologous Post-baseline Hematopoietic Stem Cell Transplant (HSCT) [From baseline HSCT until the end of study, up to 30 months]

      The percentage of responders per investigator's review (participants who achieved either CMR or PMR during the treatment) who have undergone allogeneic (allo) HSCT or autologous (auto) HSCT while in remission and without any other anti-cancer treatment.

    7. Phase 2: Cumulative Incidence Function Estimate of 100-day Mortality After HSCT Presented as Percentage of Participants That Died Not Due to Relapse, With Relapse and Death Due to Relapse as Competing Events [100 days after HSCT]

      Non-relapse mortality rate at 100 days after HSCT was calculated as the percentage of participants who died not due to relapse. Only participants who achieved a response per investigator's review and underwent autoHSCT are included.

    8. Phase 2: Blinatumomab Steady State Concentrations (Css) [Pre-dose on Day 1, and post-dose on Days 2, 9 and 16 of Cycle 1 (Cycle 1 was 70 days)]

      Pharmacokinetic (PK) parameters were estimated by non compartmental analysis. The Css of blinatumomab was summarized as the observed concentrations collected after at least 24 hours after the start of continuous IV infusion or start of dose step, where appropriate.

    9. Phase 2: Blinatumomab Clearance (CL) [Pre-dose on Day 1, and post-dose on Days 2, 9 and 16 of Cycle 1 (Cycle 1 was 70 days)]

      Serum blinatumomab CL was calculated as CL=R0/Css,DN; where R0 is the infusion rate (μg/hr) and Css,DN is the dose normalized average Css. For the CL calculation, the Css,DN was normalized to the 112 μg/day dose in which the value of dose in units of μg/hr was used for the infusion rate.

    10. Phase 2: Half-life of Blinatumomab [Pre-dose on Day 1, and Days 2, 9 and 16 of Cycle 1 (Cycle 1 was 70 days)]

    11. Phase 2: Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE) [From first dose of blinatumomab until 30 days after last dose. The maximum treatment duration for blinatumomab was 114 days]

      Treatment-emergent adverse events were events with an onset after the administration of the first dose of blinatumomab. TEAEs were graded using the Common Terminology Criteria for Adverse Events (CTCAE). Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limited age appropriate instrumental activities of daily life (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolonged hospitalization indicated; disabling; limited self care ADL. Grade 4 Life-threatening consequences; urgent interventions indicated.

    12. Phase 3: Objective Response Rate (ORR) [Up to 12 weeks after first dose of study treatment]

    13. Phase 3: Progression Free Survival (PFS) [From first dose of study treatment until the end of study, up to 30 months]

    14. Phase 3: Duration of Response (DOR) [From first dose of study treatment up to 12 weeks]

    15. Phase 3: Percentage of Participants Who Experienced Successful Mobilization [From baseline until the end of study, up to 30 months]

    16. Phase 3: Percentage of Participants Who Had Allogeneic or Autologous Post-baseline Hematopoietic Stem Cell Transplant (HSCT) [From baseline HSCT until the end of study, up to 30 months]

    17. Phase 3: Percentage of Participants Who Died Within 100 Days After Hematopoietic Stem Cell Transplantation (HSCT) That Was Not Due to Relapse [100 days after HSCT]

    18. Phase 3: Change From Baseline in Patient Reported Clinical Outcome Assessments Quality of Life (QOLCOA) Scores [Up to 30 days after last dose after study treatment]

    19. Phase 3: Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE) [From first dose of study treatment until 30 days after last dose]

    20. Phase 3: Serum Blinatumomab Steady State Concentration (Css) [24 hours after first dose of blinatumomab]

    21. Phase 3: Blinatumomab Clearance (CL) [Pre-dose on Day 1, and Days 2, 9 and 16 of Cycle 1 (Cycle 1 was 70 days)]

    22. Phase 3: Half-life of Blinatumomab [Pre-dose on Day 1, and Days 2, 9 and 16 of Cycle 1 (Cycle 1 was 70 days)]

    Certain Agreements

    Principal Investigators are NOT employed by the organization sponsoring the study.

    The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results after completion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
