Safety Study of Gene Modified Donor T-cells Following Partially Mismatched Stem Cell Transplant
Sponsor: Bellicum Pharmaceuticals
Summary
This study will evaluate patients with blood cell cancers who are going to have an allogeneic (donor) blood stem cell transplant from a partially matched relative. The research study will test whether immune cells, called T cells, which come from the donor relative and are specially grown in the laboratory and then given back to the patient along with the stem cell transplant (T cell addback), can help the immune system recover faster after the transplant. As a safety measure, these T cells have been "programmed" with a "self-destruct switch" so that if, after they have been given to the patient, the T cells start to react against the tissues (called "graft versus host" disease, GVHD), the T cells can be destroyed.

Interventions
BPX-501 dose 1
Subjects will receive 2x10E5 donor T cells/kg genetically modified with BPZ-1001 retroviral vector containing the iCasp suicide gene (BPX-501) after stem cell transplant.
Rimiducid
Dimerizer drug administered by intravenous infusion in those subjects who develop GVHD after infusion of BPX-501 cells.
BPX-501 dose 2
Subjects will receive 5x10E5 donor T cells/kg genetically modified with BPZ-1001 retroviral vector containing the iCasp suicide gene (BPX-501) after stem cell transplant.
BPX-501 dose 3
Subjects will receive 1x10E6 donor T cells/kg genetically modified with BPZ-1001 retroviral vector containing the iCasp suicide gene (BPX-501) after stem cell transplant.
BPX-501 dose 4
Subjects will receive 3x10E6 donor T cells/kg genetically modified with BPZ-1001 retroviral vector containing the iCasp suicide gene (BPX-501) after stem cell transplant.
SCT
all subjects will receive an alpha beta depleted donor transplant as part of treatment
