Brief Summary:
A Phase I study of BPX-501 T cell infusion in adults with recurrent or minimal residual disease (MRD) hematologic malignancies post-allogeneic transplant. The treatment consists of increasing doses of BPX-501 T cell infusions to achieve a clinical response. AP1903 will be investigated for the treatment of aGvHD after BPX-501 T cell infusion to determine a dose that can mitigate GvHD and preserve the graft versus leukemia effect.

Detailed Description:
Unmanipulated donor lymphocyte infusion (DLI) is used after stem cell transplantation to treat and prevent relapse, to prevent infections and to establish full donor chimerism. The addition of mature T cells which exhibit a broad repertoire of T cell immunity against viral and cancer antigens, might provide a clinical benefit. However, an expected side effect of the presence of mature T cells is the potential occurrence of acute graft-versus-host disease (aGVHD). BPX-501 contains genetically modified donor T cells that have an inducible safety switch iCasp9 suicide gene. Evidence has emerged that escalating DLI has achieved higher clinical response rate with lower GVHD occurrence. Optimization of DLI dose and schedule as well as strategies of donor T-cell manipulation may lead to the consistent ability to separate GVHD from GvL (graft-versus-leukemia) activity and improve the safety of DLI treatment.

Arm Intervention/treatment
Experimental: BPX-501 and AP1903

All subjects will receive 3 cycles of BPX-501 T cell infusions at escalating dose levels (DL). DL1 on Day 0, DL2 on Days 30 and 60. The first dose of BPX-501 T cells will occur ≥30 days after hematopoietic stem cell transplant (HSCT).

Two doses of AP1903 ( 0.1 mg/kg and 0.4 mg/kg) will be investigated for the treatment of aGvHD after BPX-501 T cell infusion.

 Biological: BPX-501
Biological: T cells transduced with CaspaCIDe suicide gene

Drug: AP1903
AP1903 administered to treat GVHD
Other Name: Rimiducid


Outcome Measures

Primary Outcome Measures :
  1. Adverse events [ Time Frame: 1 year ]
    To evaluate the safety of 2 stratified dose levels of BPX-501 T cell infusions based on patient-donor match in adult subjects with hematological malignancies

  2. Adverse events [ Time Frame: 36 hours ]
    evaluate the safety of the infusion of escalating doses of dimerizer drug rimiducid (AP1903) in subjects who develop acute GvHD after BPX-501 infusion


Secondary Outcome Measures :
  1. Response Rate [ Time Frame: 2 years ]
    Measure overall survival and disease free survival 2 years after BPX-501 infusion
