 (submitted: June 8, 2019)
Safety and tolerability of combined DLI and blinatumomab treatment in subjects with treatment-resistant MC or MRD of CD19+ B-precursor ALL after allogeneic SCT [ Time Frame: 18 weeks ]
Subject incidence and grade of adverse events (AEs) including graft-versus-host disease (GvHD). The intensity of (S)AEs will be assessed according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), version 4.03.

Current Secondary Outcome Measures  ICMJE
 (submitted: June 8, 2019)
  • Efficacy of a combined treatment of DLI and blinatumomab to induce a complete MRD/chimerism response [ Time Frame: 18 weeks ]
    MRD response based on RT-PCR: Complete MRD response (MolCR): hCR and MRD not detectable by molecular probe[s] with a sensitivity ≥10−4. The MRD response is calculated as: [number of patients achieving complete MRD response after at least one cycle (minimum 4 days blinatumomab) of study treatment] / [number of patients who received at least 1 cycle (minimum 4 days blinatumomab) of study treatment]. Mixed chimerism response: CC response: only donor STRs in bone marrow; Low-level MC response ≥90% but <100% donor STRs in bone marrow. The MC response is calculated as: [number of patients achieving CC/low-level MC response after at least one cycle (minimum 4 days blinatumomab) of study treatment] / [number of patients who received at least 1 cycle (minimum 4 days blinatumomab) of study treatment].
  • Duration of the response and survival after combined treatment of DLI and blinatumomab [ Time Frame: 18 weeks ]
    For patients who received at least one cycle (minimum 4 days of blinatumomab), progression-free survival and overall survival will be calculated using kaplan-meier survival estimates. Descriptive summary statistics (N, mean, standard deviation, minimum, median and maximum) for the duration of response will be performed for all patients with an observed complete MRD response or CC/low-level MC response.

Brief Summary This phase 2 study is designed to evaluate the safety, tolerability and efficacy of allogeneic donor lymphocyte infusions (DLI) combined with the bispecific T cell engager blinatumomab in B-precursor ALL patients who have mixed chimerism (MC) or are MRD-positive after allogeneic SCT and are refractory to at least one MRD- or MC-targeted therapy (i.e. blinatumomab, DLI, tyrosine kinase inhibitors or other agents).

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Adult patients with CD19+ B-precursor ALL (as determined by immunophenotyping) in hCR (defined as having less than 5% blasts in bone marrow) after allogeneic SCT.
  2. One, or a combination of the following documented after an interval of at least 2 weeks since cessation of the most recent leukemia-targeting therapy (i.e. chemotherapy, immunotherapy or cellular therapy, except for intrathecal prophylaxis):

    • Positivity for CD19+ MRD (molecular failure or molecular relapse), defined as presence of MRD at a level of ≥10^-4 according to an assay with a minimum sensitivity of 10^-4.
    • Donor chimerism <90%, as determined by analysis of host and donor STRs in bone marrow sample engraftment analysis.
  3. At least one previous line of treatment for MRD-positivity and/or reduced donor chimerism (i.e. blinatumomab, DLI, TKI or other agents) after allogeneic SCT.
  4. For those with BCR/ABL-positive B-precursor ALL only: persistence of MRD and/or MC following at least one ≥ second generation TKI (dasatinib, nilotinib, bosutinib, ponatinib) OR intolerance to second generation TKI and intolerance to or persistence of MRD and/or MC following imatinib mesylate.
  5. Availability of allogeneic donor lymphocytes from the subject's donor (at least 2 x 10^8 T cells/kg).
  6. Subject has provided written informed consent prior to initiation of any study-specific activities/procedures.
  7. Subject has provided informed consent to be followed up in the GMALL-Registry.
  8. Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤ 2.

  10. Hepatic function as follows:

    • Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) ≤ 3.0 x upper limit of normal (ULN)
    • Alkaline phosphatase (ALP) < 3.0 x ULN
    • Bilirubin ≤ 2.0 x ULN (unless considered due to Gilbert's syndrome or hemolysis)
