Interventions

  • Aspirin — DRUG
    Aspirin, also known as acetylsalicylic acid (ASA), is a very safe medication used to treat pain, fever, or inflammation.
  • Osimertinib — DRUG
    Osimertinib, also known as azd9291, is a 3rd-generation EGFR-TKI used to treat NSCLC patients with resistance to 1st generation EGFR-TKI due to T790M mutation. It has been approved in clinical applications by the FDA in 2015.

Study Details

The third generation epidermal growth gactor receptor-tyrosine Kinase Inhibitor（EGFR-TKI） osimertinib has obvious curative effect for EGFR sensitive mutation and T790M mutation(PMID 27959700), but acquired drug resistance will occur. Previous studies show that apoptosis escape can lead to EGFR-TKI resistance.Osimertinib resistant cells show abnormal activation of PI3K/AKT/BIM activation(PMID 28765329). The classical drug aspirin can effectively decrease AKT phosphorylation and activate of BIM(PMID 28881293).So Investigators speculate that aspirin may decrease the PI3K/AKT/BIM signaling pathways, then promote osimertinib resistant cells apoptosis. The current study aims to evaluate the combination of aspirin and osimertinib in patients with EGFR/T790M mutations.

Arms

  • Arm: osimertinib and aspirin
    Osimertinib and Aspirin starting at a dose of 80 mg and 100mg once a day, orally with meals. Aspirin treatment will be initiated one week before beginning TKI therapy, if possible, but TKI therapy will not be delayed for Aspirin loading. Drug: Osimertinib and Aspirin will be administered once every day. If subject has complete response, partial response, stable disease, or unacceptable toxicity.
  • Arm: osimertinib
