Clinical Trial Summary

A prospective, multicenter clinical study designed to explore the efficacy of postoperative adjuvant EGFR-TKIs therapy based on MRD status in patients with stage IB-IIIB EGFR-mutant non-squamous non-small cell lung cancer (non-squamous NSCLC). Primary endpoints include 3-year Disease-Free Survival rate (3y-DFS) and median disease-free survival (mDFS).


Description:

All subjects enrolled in this clinical trial will receive peripheral blood MRD status assessment within 1 week and 1 month after surgery, and will be divided into MRD positive group (+) and MRD negative group (-) according to their results , followed by MRD status assessment every 12 weeks. The MRD positive group would receive icotinib as adjuvant treatment. When the peripheral blood MRD turned negative, the subjects entered the drug withdrawal observation period. When the MRD turned positive again, the subjects resumed icotinib treatment. If EGFR T790M mutation was found, researchers would resume medication and choose osimertinib therapy. The MRD negative group (-) directly entered the follow-up observation period. When the MRD status of peripheral blood turned positive, the subjects received osimertinib treatment. When the MRD turned negative again, the subjects entered the drug withdrawal observation period.

Eligibility Inclusion Criteria: 1. Written informed consent provided. 2. Males or females aged =18 years, < 80 years. 3. Able to comply with the required protocol and follow-up procedures, and able to receive oral medications. 4. Target population is completely resected pathological stage IB-IIIB NSCLC with EGFR exon 19 deletions, L861Q mutation, G719X mutation and exon 21 L858R activating mutation. 5.

Adequate liver function: Total bilirubin = 1.5 x upper limit of normal (ULN), Aspartate aminotransferase (AST), alanine aminotransferase (ALT) = 2.5 x ULN in subjects without liver metastases; = 5 x ULN in subjects with liver metastases. 10. Adequate renal function: Serum creatinine = 1.25 x ULN, or = 60 ml/min. 11. Female subjects should not be pregnant or breast-feeding. Exclusion Criteria: 1. Known severe hypersensitivity to icotinib, osimertinib or any of the excipients of this product. 2. Inability to comply with protocol or study procedures. 3. A serious concomitant systemic disorder that, in the opinion of the investigator, would compromise the patient's ability to complete the study. 4. A serious cardiac condition, such as myocardial infarction within 6 months, angina, or heart disease. 5. Interstitial pneumonia. 6. Patients with prior exposure to agents directed at the HER axis (e.g. erlotinib, gefitinib, icotinib, cetuximab, trastuzumab). 7. Patients with prior chemotherapy or therapy with systemic anti-tumour therapy (e.g. monoclonal antibody therapy). 8. Patients with prior radiotherapy to primary lesion or lymph nodes. 9. History of another malignancy in the last 5 years with the exception of the following: Other malignancies cured by surgery alone and having a continuous disease-free interval of 5 years are permitted. Cured basal cell carcinoma of the skin and cured in situ carcinoma of the uterine cervix are permitted. 10. Any unstable systemic disease (including active infection, uncontrolled hypertension (systolic pressure > 160mmHg, diastolic pressure > 100mmHg), unstable angina, congestive heart failure, myocardial infarction within the previous year, serious cardiac arrhythmia requiring medication, hepatic, renal, or metabolic disease). 11. Eye inflammation or eye infection not fully treated or conditions predisposing the subject to this. 12. Evidence of any other disease, neurological or metabolic dysfunction, physical examination or laboratory finding giving reasonable suspicion of a disease or condition that contraindicated the use of an investigational drug or puts the subject at high risk for treatment-related complications. 13. Patient who has active serious infection (e.g. pyrexia of or 38.0? over) Patients who harboring exon 20 T790M mutation, EGFR 20 insertions, ALK fusion, BRAF V600E mutation, MET amplification and KRAS mutation.

Intervention

Genetic:
Adjuvant treatment for MRD positivity
The MRD positive group would receive icotinib as adjuvant treatment. When the peripheral blood MRD turned negative, the subjects entered the drug withdrawal observation period. When the MRD turned positive again, the subjects resumed icotinib treatment. If EGFR T790M mutation was found, researchers would resume medication and choose osimertinib therapy.
