In 2017, the FDA approved the first ever gene immunotherapy to treat cancer. It is called chimeric antigen receptor T-cell therapy or CAR-T, for short. The one-time treatment is now being used to treat some adults and children with certain types of blood cancers.
Chimeric antigen receptor T-cell therapy or CAR-T is a personalized cancer therapy that teaches the immune system's T cells to target cancer cells
There is currently no CAR-T immunotherapy approved to treat breast cancer. But researchers are investigating whether CAR-T and other types of gene therapies might be effective in treating solid tumors, like breast cancer, and a few clinical trials have already gotten underway.
The clinical trials currently studying CAR-T in breast cancer can be found here on BreastCancerTrials.org.
