Encorafenib is a targeted therapy drug designed for cancer patients harboring BRAF V600E or V600K mutations. It is typically used in combination with binimetinib to treat malignant tumors such as unresectable or metastatic melanoma and non-small cell lung cancer. By inhibiting the activity of abnormal BRAF proteins and blocking tumor growth signaling pathways, it offers a new therapeutic option for patients for whom traditional treatments have proven ineffective or who have developed resistance.
