Clinical Trial

Disease: Relapsed or Refractory Multiple Myeloma, MM, (NCT05000450)

Disease info:

Multiple myeloma is a cancer that develops in the bone marrow, the spongy tissue found in the centre of most bones. Multiple myeloma is characterised by abnormalities in plasma cells, a type of white blood cell. In myeloma, these abnormal cells multiply uncontrollably, increasing from about one percent of cells in the bone marrow to the majority of bone marrow cells. The abnormal cells form tumours within the bone, causing bone pain and an increased risk of fractures.

Relapsed myeloma refers to when a patient had active treatment that their disease responded to, went off treatment and then the disease came back. 

Refractory myeloma is a disease that is progressing despite active treatment.


Multiple myeloma occurs in approximately 4 per 100,000 people per year; there are currently about 100,000 affected individuals in the United States.

Allogene developed the TurboCAR technology to further enhance the potency of cell therapies. This technology allows ligand independent, cytokine signaling to be engineered selectively into CAR T cells. TurboCARs have the potential to enhance AlloCAR T cell proliferation and overcome T cell exhaustion

ALLO-605: B-Cell Maturation Antigen (BCMA) CAR T cells were generated from healthy donor T cells by lentiviral transduction with a CAR construct followed by genetic inactivation of the T-Cell Receptor Alpha Constant (TRAC) and CD52 loci using TALEN gene editing. Allogeneic BCMA TurboCAR T cells, engineered for stoichiometric expression of the CAR and a Constitutively Active Chimeric Cytokine Receptor (CACCR) via a self-cleaving peptide, were produced similarly.
