Study of ATLCAR.CD138 Cells for Relapsed/Refractory Multiple Myeloma

Running, not enrolling · Phase 1

Conditions studied: Multiple Myeloma, Immune System Diseases

In brief

The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding those bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat subjects with cancers. They both have shown promise, but neither alone has been sufficient to cure most subjects. This study is designed to combine both T cells and antibodies to create a more effective treatment. The treatment that is being researched is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD138 antigen (CAR138 T cells). In previous studies, it has been shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. A gene is a unit of DNA. Genes make up the chemical structure carrying the subject's genetic information that may determine human characteristics (i.e., eye color, height and sex). The new gene that is put in the T cells in this study makes a piece of an antibody called anti-CD138. This antibody floats around in the blood and can detect and stick to cancer cells called multiple myeloma cells because they have a substance on the outside of the cells called CD138. Anti-CD138 antibodies have been used to treat people with multiple myeloma, but have not been strong enough to cure most subjects. For this study, the anti-CD138 antibody has been changed so that instead of floating free in the blood part of it is now joined to the T cells. Only the part of the antibody that sticks to the multiple myeloma cells is attached to the T cells instead of the entire antibody. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD138 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown.
