What type of cancer is targeted therapy used for?
Examples: alemtuzumab (certain chronic leukemias), trastuzumab (certain breast cancers), cetuximab (certain colorectal, lung, head and neck cancers).

What is the new cancer treatment?
The FDA has approved a form of gene therapy called CAR T-cell therapy. It uses some of your own immune cells, called T cells, to treat your cancer. Doctors take the cells out of your blood and change them by adding new genes so they can better find and kill cancer cells.
What are the disadvantages of targeted therapy?
Targeted therapy does have some drawbacks. Cancer cells can become resistant to targeted therapy. Resistance can happen when the target itself changes and the targeted therapy is not able to interact with it. Or it can happen when cancer cells find new ways to grow that do not depend on the target.

Phase 0 trials are very small trials that help researchers decide if a new agent should be tested in a phase 1 trial.
What are the phases of cancer?
During the early phases (phases 1 and 2) , researchers figure out whether a new treatment is safe, what its side effects are, and the best dose of the new treatment. They also make sure that the treatment has some benefit, such as slowing tumor growth. In the later phase (phase 3), researchers study whether the treatment works better than ...
What is phase 3 in a study?
