Everolimus

Everolimus acts as a sophisticated "circuit breaker" for cancer. Tumors are addicted to growth signals sent by the mTOR protein—it tells them to divide and build new blood vessels. Everolimus cuts this line of communication, effectively starving the tumor and halting its expansion. It is a game-changer for breast cancer patients whose disease has outsmarted hormone therapy, and a key weapon against kidney cancer and neuroendocrine tumors (NETs).
