Researchers at Fred Hutch are focused on developing novel kidney cancer immunotherapies. One of the main targets of this research is 5T4, a well- characterized kidney cancer marker that is found on the surface of almost all kidney cancer cells and rarely in a healthy cell. Work has been completed to validate 5T4 as a potential target. The team is now developing genetically engineered T cells that recognize and attack 5T4-bearing cancer cells using an optimized T-cell receptor (TCR). Their final goal is to provide a TCR-based immunotherapy for infusions of autologous T cells to treat kidney cancer. A recent clinical trial for a 5T4-based vaccine has shown no safety concerns from 5T4 being targeted by the immune system. The team’s TCR immunotherapy approach offers an improvement to the vaccine approach. A vaccine will only work in a minority of patients that already possess T cells that recognize the specific markers in the vaccine, whereas the TCR immunotherapy approach provides all treated patients with an arsenal of properly-targeted T cells.

Kidney cancer is diagnosed in over 62,000 Americans each year and is the cause of 14,000 deaths. It is very difficult to cure once it has spread outside the kidneys. In 2016, the kidney cancer diagnostics and therapeutics market was valued at $3.11 billion and expected to grow with a CAGR of 5.64% over the next five years.
