Abstract: The present invention refers to a method of treating tumor growth and metastasis in a mammal, said treating comprising administering allogenic effector cells together with trifunctional bispecific or trispecific antibodies or a combination thereof having the following properties: a) binding to a T cell b) binding to at least one antigen on a tumor cell c) binding via their Fc portion in the case of trifunctional bispecific antibodies or via third specificity in the case of trispecific antibodies to Fc receptor positive cells said antibodies redirecting the allogenic cells away from host tissues in order to substantially reduce or avoid a graft versus host disease.

Abstract: A composition comprising bone marrow cells (BMC) and demineralized bone matrix (DBM) and/or mineralized bone matrix (MBM), optionally comprising bone morphogenetic protein (BMP), particularly for use in bone marrow transplantation, into bone marrow cavity or into extraskeletal sites, and methods of transplantation/implantation thereof. The composition and methods of the invention enable restoring and/or enhancing the formation of hematopoiectic microenvironment originating from the transplanted BMC, and are useful in the treatment of hematopoietic disorders, such as deficiency of stem cells and/or their products, genetic conditions resulting in abnormal stem cells and/or products, or hematopoietic disorders of malignant or non-malignant origin.

Abstract: Serious hematologic malignancies are treated through high dose or lethal chemotherapy and/or radiation therapy conditioning regimens followed by rescue with allogeneic stem cell transplantation (allo-SCT) or autologous stem cell transplantation (ASCT). These myeloablative/lymphoablative (M/L) treatment regimens involve the elimination of both the patient's hematopoietic stem cells and T-lymphocytes, often leading to serious complications including graft versus host disease (GVHD). The claimed invention addresses some of these problems by providing a conditioning regimen that is designed to eliminate the patient's T-lymphocytes while retaining a functional population of hematopoietic stem cells (HSC). This non-myeloablative/lymphoablative (-/L) conditioning regimen involves the administration of one or more agents such as purine analogs (e.g., fludarabine), alkylating agents (e.g., bisulfan, cyclophosphamide), or anti-leukocyte globulins (e.g., anti-T lymphocyte globulin).

Abstract: Methods have been discovered for treating minimal residual disease following removal of most or a substantial fraction of malignant cells from a cancer patient. An autologous stem cell transplant is performed on the patient. Following partial hematopoiesis recovery, the patient is infused with allogeneic peripheral blood lymphocytes, either alone or in combination with in vivo or in vitro cytokine. The infused allogeneic lymphocytes engender an anti-malignant cell response and can be instrumental in prevention of disease relapse.

Abstract: The present invention features a method of inducing donor-specific tolerance in a host. Tolerogenic treatments of the present invention may be administered to a host prior to transplantation of donor-derived materials. The tolerogenic treatment involves (1) administering an immunosuppressive agent to a host mammal in a non-myeloablative regimen sufficient to decrease, but not necessarily to eliminate, the host mammal's functional T lymphocyte population; (2) infusing donor antigens from a non-syngeneic donor into the host mammal; (3) eliminating those host T lymphocytes responding to the infused donor antigens using a non-myeloablative dose of lymphocytotoxic or tolerizing agent; and (4) administering donor hematopoietic cells to the host mammal. Donor lymphoid cells used for cell therapy of a host mammal can be depleted of host specific immunological reactivity by methods essentially similar to those use for tolerizing a host mammal prior to transplantation.
