. EGFR is used by normal cells, but certain cancers produce much higher levels of it, which fuels their growth. In 2015, the Food and Drug Administration approved osimertinib to treat advanced non-small cell lung cancers that carried one specific EGFR-related mutation. Since then, AstraZeneca has sought to show that itsover the weekend in the New England Journal of Medicine. It
looks at long-term data from the company’s ADAURA Phase III trial. The trial involved 682 patients diagnosed with early-stage EGFR-mutated NSCLCs who had their tumors completely removed with surgery. The patients were randomized to receive osimertinib or a placebo. The patients had their tumors detected early enough that they could possibly be cured with surgery alone. But these cancers frequently recur and often become fatal. In this trial, however, those taking osimertinib had a noticeably higher chance of survival. Across both the primary analysis and secondary analysis , the drug was found to reduce the risk of dying five years after treatment by 51%.
AstraZeneca plans to release more data showing the effectiveness of using osimertinib in combination with standard chemotherapy to treat advanced EGFR-mutated lung cancers later this year. But outside researchers and advocates are already excited about the drug’s potential to become a frontline treatment for these patients.
