Colorado’s Medicare provider has announced that it will cover VeriStrat, a test designed to guide decisions about second-line therapies for advanced non-small cell lung cancer (NSCLC). The main second-line therapy options in NSCLC include chemotherapy or the drug erlotinib (Tarceva). While Tarceva can significantly improve outcomes in patients with mutations in the EGFR gene, it also benefits some patients without these mutations. VeriStrat, a rapid blood test, helps predict which of these patients would be more likely to respond to Tarceva and which would be better served by other treatments. Medicare coverage will allow many more patients in Colorado to access this useful tool.
