Multi-institutional Prospective Research of Expanded Multi-antigen Specifically Oriented Lymphocytes for the Treatment of VEry High Risk Hematopoietic Malignancies

Description

This Phase I dose-escalation trial is designed to evaluate the safety of administering rapidly -generated tumor multi-antigen associated -specific cytotoxic T lymphocytes, to HSCT recipients (Arm A) or future HSCT recipients (Arm B) for the treatment of high-risk or relapsed or refractory hematopoietic malignancies. In addition to safety, this study will also evaluate if event-free survival (EFS) is improved with TAA-T administration at six months after HSCT for patients with high risk AML and MDS (Arm C).

Conditions

Relapsed/Refractory Hematopoietic Malignancies, Acute Myeloid Leukemia and MDS

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Aged 6 months to 80 years
  • * Received prior or anticipated myeloablative or non-myeloablative allogeneic hematopoietic stem cell transplant
  • * Patients (Arm A) who have undergone allo-HSCT with high risk or relapse or residual/recurrent disease (see below) OR patients (Arm B) with high risk or relapsed/refractory disease (\> 2 regimens with greater than M1 marrow or persistent HD) with anticipated allo-HSCT:
  • * Acute lymphoblastic leukemia (ALL), Acute myeloid leukemia (AML), Ambiguous lineage leukemia or lymphoma, Chronic Myelogenous leukemia (CML), CMML, MDS:
  • * Evidence of active leukemia or lymphoma disease by flow cytometry, morphology, or cytogenetic evaluation within the marrow or extramedullary sites.
  • * Hodgkin's Lymphoma that has failed or are intolerant of Brentuximab, Non-Hodgkin Lymphoma (NHL) including Grey Zone Lymphoma, Anaplastic large cell lymphoma (ALCL), and mantle cell lymphoma:
  • * Evidence of lymphoma by morphology, Positron Emission Tomography (PET)/ Computed tomography (CT) uptake in a site of previous disease in the absence of other etiologies.
  • * ARM C only includes patients with high risk AML and MDS who have received an allo-HSCT and have not had hematologic relapse of disease.
  • * Karnofsky/Lansky score of ≥ 50
  • * Agree to use contraceptive measures during study protocol participation (when age appropriate)
  • * Patient or parent/guardian capable of providing informed consent.
  • * T cell chimerism \> 94% if collected from recipient of allo-HSCT (performed within the last 6 months)
  • * If the product is procured from the recipient in the autologous (Arm B) setting, the absolute lymphocyte count should be greater than or equal to 600 for procurement. Please note: If a patient has already undergone an allogeneic HSCT, it is NOT allowed to generate TAA-T from patient blood collected post-HSCT under Arm A or C
  • * Patients with uncontrolled infections
  • * Current evidence of GVHD \> grade 2 or bronchiolitis obliterans syndrome, sclerotic GVHD, or serositis Pregnancy or lactating (female of childbearing potential) Recipient Inclusion criteria for initial TAA-T administration and for subsequent infusions
  • * Patients (Arm A) who have undergone allo-HSCT with high risk or relapse or residual/recurrent disease (see below) OR patients (Arm B) with high risk or relapsed/refractory disease (\> 2 regimens with greater than M1 marrow or persistent HD) with anticipated allo-HSCT:
  • * Steroids less than 0.5 mg/kg/day prednisone or equivalent.
  • * Karnofsky/Lansky score of ≥ 50.
  • * Bilirubin \< 2.5 mg/dL, AST/ALT \<5x upper limit of normal, Serum creatinine \< 1.0 or 2x the upper limit of normal (whichever is higher).
  • * Pulse oximetry of \> 90% on room air.
  • * Absolute neutrophil count \> 250/ µL (may be supported with Granulocyte colony-stimulating factor (GCSF)).
  • * Agree to use contraceptive measures during study protocol participation (when age appropriate).
  • * Patient or parent/guardian capable of providing informed consent.
  • * LVEF \> 50% or LVSF \> 27% (performed within the last 6 months) if history of TBI \>500 cGy for arm A and B.
  • * Total chimerism \> 50%; or if cancer cells preclude this, donor T cell chimerism \> 50% (performed within the last 6 months).
  • * Patients who received ATG, Campath, or other T cell immunosuppressive monoclonal antibodies within 28 days prior to TAA-T infusion.
  • * No investigational therapies (under IND, not extensively studied in the current clinical context) within 28 days prior to TAA-T infusion.
  • * Uncontrolled infections
  • * Active Bronchiolitis obliterans syndrome, sclerotic GVHD, or serositis
  • * Current evidence of GVHD \> grade 2 for Arm A and B; Active GVHD of any grade is exclusion for arm C patients.
  • * Pregnancy or lactating (female of childbearing potential)
