Summary

Brief summary

Patients with some forms of acute myeloid leukemia (AML) and multiple myeloma (MM) are not cured with conventional therapy and new approaches are needed. For the last 15 years we have investigated the potential of using a patient's own T cells (a type of white blood cell \[WBC\]) to eradicate the tumor. We have demonstrated the feasibility of this approach in cell culture and animal models of AML and MM. Over the last 5 years we have been preparing to treat patients as part of a Phase I (first in human) clinical trial.

The trial treatment involves collecting the patient's own WBCs from the blood by a standard well established and safe process called apheresis. The cells are then cultured in a specialized laboratory (under Good Manufacturing Practice conditions, similar to standards under which pharmaceuticals are produced) over 12 days to convert the cells to specialized tumor-attacking T cells. Early in that culture process the cells are exposed to a virus (that is modified so that it cannot infect or replicate outside the special culture conditions) that contains a special gene. Via the virus, this gene inserts into the patient's T cells in culture and gets incorporated into the T cell's genetic machinery. As the T cells replicate, the new gene produces a protein receptor that becomes part of the patient's T cells. This protein receptor on the T cells has the capacity to specifically recognize and bind to a protein on the leukemia or myeloma cells called the "Lewis Y" antigen.

After the modified T cells are infused into the patient, they home into the bone marrow (this tracking is monitored by special radiological techniques) where the new protein receptor on the T cell surface can recognize and bind to the cancer cells (which express Lewis Y). Once bound onto the cancer cells, the T cells get activated and subsequently replicate and kill the cancer cells. The novelty of this approach is that the T-cells will only kill cells that have the Lewis Y on their surface - the cancer cells. Moreover, because there are few normal cells in a person's body that carry Lewis Y, this treatment is likely to only have minor side effects.

This gene therapy trial is unique and although the primary purpose is to test the safety of this approach, patients will be monitored closely for anti-tumor responses. As the trial progresses, the dose of T cells infused will increase, in the hope that this will result in a better and stronger immune response to the leukemia or myeloma.
