Allogeneic cell therapy is a type of cell therapy in which a patient receives cells from a donor.
Allogeneic cell therapy is a type of cell therapy in which a patient recieves cells from a donor. Bone marrow transplants are a type of allogeneic cell therapy. Allogenic therapy products may also be called universal cell therapy product or off-the-shelf cell therapy products. Autologous cell therapy uses cells which are derived from a patient’s own cells. Allogeneic cell therapies carry the risk of immune rejection but also have potential advantages over autologous cell therapy. Since cells do not need to be extracted from the patient and prepared, allogeneic cell therapy products are more immediately available to the patient. Allogeneic cell therapy products could potentially allow less variability, more standardization and allow for an industrialized process to decrease the cost of production.
Mesenchymal stromal cells (MSCs) are a heterogeneous population of cells that when expanded in vitro include stem, progenitor and differentiated cells. MSCs have been have regenerative potential and anti-inflammatory properties. However, MSC treatments in clinical trials have produced mixed results. No cell therapies using MSCs have been FDA approved.

Cancer immunotherapies are treatments that activate or strengthen immune response to cancer cells or preventing tumor cells from suppressing the body’s immune response. T cells and natural killer (NK) cells are among the immune cells with antitumour activity. Chimeric antigen receptor-engineered (CAR) T cell therapy treats a patient with T cells that are modified to have enhanced targeting toward cancer cells. CAR NK cells are NK cells with enhanced cancer targeting.
Allogene Therapeutics developed ALLO-715 and ALLO-647, two allogeneic CAR T cell therapies in cancer clinical trials as of 2023.ALLO-715 is an allogeneic, anti-BCMA CAR T cell therapy developed to treat multiple myeloma. ALLO-715, manufactured by Allogene is prepared from peripheral blood mononuclear cells from healthy donors. ALLO-715 targets BCMA, a protein expressed on the surface of mature B lymphocyte and plasma cells that plays a role in myeloma cell survival and proliferation. BCMA is a target for multiple myeloma because it is overexpressed and activated in multiple myeloma.
TheAs firstof 2021 most CAR T therapies developed toin treatclinical cancertrials were autologous CAR T cell therapies. All FDA approved CAR T therapies (Abecma, Breyanzi, Carvykti, Kymriah, Yescarta) are autologous cell therapies. Allogeneic CAR T therapies are in preclinical and clinical development.
Allogeneic NK cells do not cause graft-versus-host disease (GVHD), giving them an advantage over allogeneic CAR T-cell therapies. Other advantages of NK cell therapies over CAR T-cell therapies include reduced cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome toxicity.

Congenital athymia is disease characterized by the absence of a functioning thymus, which results in profound immunodeficiency, increased susceptibility to infections and an increased risk of graft-versus-host disease (GVHD). Most infants with congenital athymia have CHARGE syndrome or have a deletion of genetic material at chromosome 22q11.2. Infants have a higher risk of congenital athymia if they were exposed to retinoic acid during pregnancy or were born to diabetic mothers.
The following products are hematopoietic progenitor cells (HPC) derived from umbilical cord blood used for treatment of disorders affecting the hematopoietic system that are inherited, acquired or resulting from myeloablative treatment.
Natural killer (NK) cells are a type of lymphocyte, or white blood cell, that control viral infections and recognize and kill malignant cells. NK cells also produce cytokines and chemokines, secreted signaling molecules that regulate other cells in inflammatory and immune responses. The three main sources of allogeneic NK cells are 1) donor peripheral blood, 2) Cord blood or differentiation from cord blood hematopoietic stem and progenitor cells (HSPCs) or 3) induced pluripotent stem cells (iPSCs).
Allogeneic NK cells do not cause graft-versus-host disease (GVHD), giving them an advantage over CAR T-cell therapies. Other advantages of NK cell therapies over CAR T-cell therapies include reduced cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome toxicity.
