Regorafenib works by blocking proteins that signal cancer cells to divide. It also blocks proteins that signal the growth of new blood vessels that tumors need to grow. Blocking these signals keeps cancer cells from growing and spreading to other parts of the body. Regorafenib is a type of targeted therapy drug called a kinase inhibitor. It is a small-molecule drug (a drug that can enter cells easily).
Use in Cancer
Regorafenib is approved to treat:
- Colorectal cancer that has spread to other parts of the body. It is used in patients who have not gotten better with other treatments.

Regorafenib is also being studied in the treatment of other types of cancer.
