Method for allogeneic cell therapy

摘要

A method of manipulating allogeneic cells for use in allogeneic cell therapy providing a composition of highly activated allogeneic T-cells which are infused into immunocompetent cancer patients to elicit a novel anti-tumor immune mechanism, or “Mirror Effect”. In contrast to current allogeneic cell therapy protocols where T-cells in the graft mediate the beneficial graft vs. tumor (GVT) and detrimental graft vs. host (GVH) effects, the allogeneic cells of the present invention stimulate host T-cells to mediate the “mirror” of these effects. The mirror of the GVT effect is the host vs. tumor (HVT) effect. The “mirror” of the GVH effect is the host vs. graft (HVG) effect The anti-tumor HVT effect occurs in conjunction with a non-toxic HVG rejection effect. The highly activated allogeneic cells of the invention can be used to stimulate host immunity in a complete HLA mis-matched setting in a patient.

主权项

1. A method of allogeneic transplant into a host that provides an anti-tumor effect without GVHD toxicity to the host, the method comprising:
infusing into the host allogeneic cells of which at least a portion are activated T-cells derived from a tissue mis-matched normal donor and wherein said allogeneic cells are rejected by the host.
