What is Lumakras (sotorasib) for?
Lumakras (sotorasib) is a prescription medicine used to treat adult patients with non-small cell lung cancer (NSCLC):[1]
that has spread to other parts of the body or cannot be removed by surgery, and
whose tumor has an abnormal KRAS G12C gene, and
who have received at least one prior systemic treatment for their cancer.
It is available in tablet form containing 120 mg sotorasib.[1]
How does Lumakras (sotorasib) work?
13% of patients with NSCLC have an abnormal KRAS G12C gene. KRAS is an oncogene, a gene that is a mutated (changed) form of a gene involved in normal cell growth. It produces the mutant form of the KRAS protein, which drives the development of lung and other cancer.[2,3]
Lumakras contains the active ingredient sotorasib, which is designed to inactivate the mutated protein. Thereby it can block tumor growth and slow down the disease.[2,3]
It is not a chemotherapy, immunotherapy, or tyrosine kinase inhibitor. It’s an oral inhibitor designed specifically for patients with a KRAS G12C mutation.[2,3]
