Vismodegib Overview
-
Vismodegib is used to treat basal cell carcinoma (a type of skin cancer) in people with cancer that has spread to other parts of the body. Vismodegib is also used to treat basal cell carcinoma that cannot be treated with surgery or radiation or has come back after surgery. Vismodegib is in a class of medications called hedgehog pathway inhibitors. It works by blocking the action of a protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells and may help shrink tumors.
