About this study
Official title: A Multi-center, Prospective, Non-randomized, Open-label Study of the Efficacy and Safety of Osimertinib Combined With Aspirin in Patients With Locally Advanced or Metastatic Non-small Cell Lung Cancer Who Are T790M-positive and Resistant to First-generation Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors.
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.
Read the detailed description
Reversible small-molecule EGF receptor tyrosine kinase inhibitors (EGFR-TKI) have shown dramatic therapeutic efficacy in non-small cell lung cancer (NSCLC) patients with EGFR-activating mutations, and have been recommended as the standard first-line therapy in these patients. However, despite excellent initial clinical responses, nearly all patients eventually develop drug resistance after a median period of about 10 months(PMID 26497205). Osimertinib is a 3rd-generation EGFR-TKI used to treat NSCLC patients with resistance to 1st generation EGFR-TKI due to T790M mutation. But Osimertinib also face the problem of acquired drug-resistance(PMID 27959700). Thus, innovative treatment strategies are urgently needed to overcome therapeutic resistance to Osimertinib to improve the survival of patients with NSCLC.
Molecular mechanisms underlying acquired Osimertinib resistance are still not fully understood. Previous study showed that one principal mechanism accounting for majority of acquired resistance to Osimertinib in lung cancer is mediated by an exon 20 C797S mutation etc(PMID 29596911). More molecular mechanisms are still to be found. Apoptosis is a process of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay. Apoptosis has been found to be related to drug resistance to 1st generation EGFR-TKI(PMID 29731879). The investigators previous found apoptosis is also related to Osimertinib resistance(PMID 28765329). Therefore, promoting apoptosis may be an effective way to improve the response to Osimertinib treatment.
Investigators' group has focused on lung cancer targeted therapy for several years. Previously, investigators have reported that metformin in combination with 1st generation EGFR-TKI could enhance the effect of TKI (PMID 24644001). Therefore, investigators further asked whether the drug combination approach could overcome osimertinib resistance. Aspirin is a widely used and well-tolerated drug for Kawasaki disease, pericarditis, and rheumatic and has arisen keen interest as a potential anticancer agent ever since the report of the clinical evidence that the cancer risk and mortality are reduced in Colon cancer. Aspirin exerts remarkable antitumor properties in tumor cells and mouse models. It strongly inhibited the growth of lung cancer cells, and its combination with TKI agents, including Sorafenib (PMID: 28857200), significantly suppressed RAS-mutant cancers growth and prolonged remission in a xenograft model. Interestingly, Aspirin exposure significantly promoted the apoptosis suggesting that aspirin may overcome Osimertinib resistance by promoting the apoptosis.
Here, investigators'group observed that in clinic, several patients who took osimertinib and aspirin together have shown excellent effect.Investigators therefore conduct this clinical trial to observe whether the combination of Aspirin and Osimertinib could enhance efficacy of Osimertinib in lung cancer patients resistant to 1st generation EGFR-TKI with T790M.

What are the possible benefits and risks?

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
progression-free survival（PFS） rates according to resist 1.1 (time frame: 3years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03543683, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
