The basics
Sotorasib (brand name-Lumakras) is an FDA-approved treatment for lung cancer (non-small cell lung cancer; NSCLC) that has spread to other parts of the body or cannot be removed by surgery in adults who have received at least one other treatment.
Sotorasib is in a class of medications called KRAS inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells.
