Capmatinib is used to treat a certain type of non-small cell lung cancer (NSCLC) that has spread to other parts of the body. Capmatinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
