LumakrasTM (sotorasib) is a drug used to treat certain adults with non-small cell lung cancer (NSCLC) that has:1
- Spread to other parts of the body (metastatic) or is locally advanced (has progressed within the lung region), and
- A KRAS G12C genetic mutation, and
- Been treated with least 1 prior treatment
The U.S. Food and Drug Administration (FDA) also approved 2 companion diagnostics for Lumakras. A companion diagnostic can help determine which people are right for therapy based on tumor features. The approved companion diagnostics look for the KRAS G12C mutation. They include:1,2
- Guardant360® CDx, which uses a plasma specimen
- QIAGEN therascreen® KRAS RGQ PCR kit, which uses tumor tissue and is used if no mutation is found in the plasma sample
The FDA granted Lumakras accelerated approval. The FDA may give accelerated approval to new drugs that treat a serious health condition with few or no other treatments and have promising results. This means drugs like Lumakras can be sold sooner.1
NSCLC makes up about 80 to 85 percent of all lung cancers. About 13 percent of people with NSCLC have a KRAS G12C genetic mutation. NSCLCs with this mutation are usually resistant to other drugs used to treat lung cancer.3
