  Purpose
This study will evaluate pediatric patients with malignant or non-malignant blood cell disorders who are having a blood stem cell transplant depleted of T cell receptor (TCR) alfa and beta cells that comes from a partially matched family donor. The study will assess whether immune cells, called T cells, from the family donor, that are specially grown in the laboratory and given back to the patient along with the stem cell transplant can help the immune system recover faster after transplant. As a safety measure these T cells have been programmed with a self-destruct switch so that they can be destroyed if they start to react against tissues (Graft versus host disease).

Condition Intervention Phase
Acute Lymphoblastic Leukemia Leukemia, Acute Myeloid (AML), Child Lymphoma, Non-Hodgkin Myelodysplastic Syndromes Immunologic Deficiency Syndromes Biological: BPX-501 T cells and AP1903 Drug: AP1903 Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Extension Study of CaspaCIDe T Cells (BPX-501) From an HLA-partially Matched Family Donor After Negative Selection of TCR αβ+T Cells in Pediatric Patients Affected by Hematological Disorders

Primary Outcome Measures:
  • Number of participants with serious and non-serious adverse events [ Time Frame: 180 days ]

Estimated Enrollment: 120
Actual Study Start Date: April 2014
Estimated Study Completion Date: December 2019
Estimated Primary Completion Date: December 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BPX-501 T cells and AP1903

TCR alpha beta depleted graft infusion with addback of BPX-501 T cells.

AP1903: Dimerizer drug administered to subjects who develop Grade III-IV acute GVHD, Grade II gut/liver acute GVDH or Grade I/II skin-only acute GvHD which is non-responsive after 7 days of standard of care treatment

Biological: BPX-501 T cells and AP1903
T cells transduced with CaspaCIDe suicide gene
Drug: AP1903
AP1903 administered to treat GVHD
Other Name: rimiducid

Detailed Description:

This is a Phase 2 extension study evaluating the safety and feasibility of BPX-501 T cells infused after partially mismatched, related, TCR alpha beta T cell depleted hematopoietic stem cell transplant (HSCT) in pediatric patients. The purpose of this clinical trial is to determine whether BPX-501 infusion can enhance immune reconstitution in those patients with hematologic disorders, with the potential for reducing the severity and duration severe acute graft versus host disease (GvHD).

The trial will also evaluate the treatment of GvHD by the infusion of dimerizer drug (AP1903/rimiducid) in those subjects who present with GVHD who progress or do not respond to standard of care treatment.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Age < 18 years and > 1 month (< 1 month upon approval by Sponsor)

  5. Patients with life-threatening acute leukemia (high-risk ALL in 1st CR, ALL in 2nd CR, high-risk AML in 1st CR, AML in 2nd CR.) or myelodysplastic syndromes. Morphological CR must be documented and minimal residual disease measurement before transplantation is recommended.
  6. Non-malignant disorders deemed curable by allogeneic transplantation: a. primary immune deficiencies, b. severe aplastic anemia not responding to immune suppressive therapy, c. osteopetrosis d. selected cases of erythroid disorders such as β0 β0 thalassemia major, sickle cell disease, Diamond-Blackfan anemia.

    e. congenital/hereditary cytopenia, including Fanconi Anemia before any clonal malignant evolution (MDS, AML).

    Note: Subjects will be eligible if they meet either item 5 OR item 6.

  7. Lack of suitable conventional donor (HLA identical sibling or HLA phenotypically identical relative or 10/10 unrelated donor evaluated using high resolution molecular typing) or presence of rapidly progressive disease not permitting time to identify an unrelated donor
  8. A minimum genotypic identical match of 5/10 is required.
  9. The donor and recipient must be identical, as determined by high resolution typing, on at least one allele of each of the following genetic loci: HLA-A, HLA-B, HLA-Cw, HLA- DRB1 and HLA-DQB1.
  10. Lansky/Karnofsky score > 50
  11. Signed informed consent by the patient or the patient's parent or guardian for patients who are minors

Exclusion Criteria:

  1. Greater than active Grade II acute GvHD or chronic extensive GvHD due to a previous allograft at the time of screening
  2. Patient receiving an immunosuppressive treatment for GvHD treatment due to a previous allograft at the time of screening
  3. Dysfunction of liver (ALT/AST > 5 times normal value, or bilirubin > 3 times normal value), or of renal function (creatinine clearance <30ml/min/1.73m2)
  4. Severe cardiovascular disease (arrhythmias requiring chronic treatment, congestive heart failure or left ventricular ejection fraction < 40%)
  5. Current clinically active infectious disease (including positive HIV serology or viral RNA)
  6. Serious concurrent uncontrolled medical disorder
  7. Pregnant or breast feeding female patient
  8. Lack of parents'/guardian's informed consent for children who are minors.
