Brief Summary

This study aims to verify the efficacy and safety of osimertinib in patients with EGFR-sensitive mutation non-small cell lung cancer who progressed after adjuvant targeted therapy following radical surgery. The main questions it aims to answer is: whether EGFR-TKI is effective in the re-treatment of NSCLC after postoperative adjuvant targeted therapy relapse.

Conditions

Lung Neoplasms; Lung Cancer, Nonsmall Cell

Outcome Measures

Primary Outcomes (1)

• Objective remission rate evaluated by the investigator (ORR)

  Objective Response Rate (ORR) (per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) using Investigator assessments) is defined as the number (%) of patients with at least 1 visit response of Complete Response or Partial Response.

  Follow-up until treatment duration reached 3 years, disease progression, or other treatment termination criteria were met

Secondary Outcomes (6)

• Progression-free survival (PFS) evaluated by the investigator

  Follow-up until treatment duration reached 3 years, disease progression, or other treatment termination criteria were met

• Duration of response (DoR) evaluated by the investigator

  Follow-up until treatment duration reached 3 years, disease progression, or other treatment termination criteria were met

• Disease control rate (DCR) evaluated by the investigator

  Follow-up until treatment duration reached 3 years, disease progression, or other treatment termination criteria were met

• Overall survival (OS) evaluated by the investigator

  Follow-up until treatment duration reached 3 years, disease progression, or other treatment termination criteria were met

• Tumor response depth (DepOR) evaluated by the investigator

  Follow-up until treatment duration reached 3 years, disease progression, or other treatment termination criteria were met

Study Arms (1)

Eligibility Criteria

• Age: 18 Years - 100 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Aged 18 years or older (inclusive).
• Histologically confirmed NSCLC (according to the 8th edition of AJCC lung cancer staging standards).
• Subjects must be patients with stage IB-IIIB NSCLC after previous radical surgery, who received adjuvant targeted therapy with EGFR TKIs (first-, second-, or third-generation EGFR TKIs) after surgery, and had tumor recurrence and progression more than 3 months after the end of the adjuvant therapy course.
• Tumor tissue samples or blood samples previously diagnosed with NSCLC were confirmed to have EGFR sensitive mutations by qualified laboratory tests.
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1 and no deterioration in the previous 2 weeks, with a minimum expected survival of 12 weeks.
• Patients must have at least 1 tumor lesion that can be accurately measured at baseline, with the longest diameter ≥10 mm at baseline (if it is a lymph node, the short diameter must be ≥15 mm). The selected measurement method is suitable for accurate repeated measurements, which can be computed tomography (CT) or magnetic resonance imaging (MRI). If there is only one measurable lesion, it can be accepted as a target lesion, and a baseline evaluation of the tumor lesion must be performed at least 14 days after the diagnostic biopsy.
• Within 7 days before treatment, the international normalized ratio (INR) is ≤1.5, or the prothrombin time (PTT) and activated partial thromboplastin time (aPTT) are ≤1.5×ULN.
• Women of childbearing age should take appropriate contraceptive measures from screening to 6 months after stopping study treatment and should not breastfeed. Before starting medication, the pregnancy test is negative, or one of the following criteria is met to prove that there is no risk of pregnancy:
• Postmenopause is defined as age greater than 50 years and amenorrhea for at least 12 months after stopping all exogenous hormone replacement therapy;
• Women under the age of 50 can also be considered postmenopausal if they have amenorrhea for 12 months or more after stopping all exogenous hormone therapy and their luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels are within the laboratory postmenopausal reference range;
• Those who have undergone irreversible sterilization surgery, including hysterectomy, bilateral oophorectomy or bilateral salpingectomy, but excluding bilateral tubal ligation.
• Male patients should use barrier contraception (i.e. condoms) from screening to 6 months after stopping study treatment.
• The subjects themselves voluntarily participate and sign the informed consent in writing.

You may not qualify if:

• Patients who have received any of the following anti-tumor treatments:
• a) Patients who have received platinum-containing chemotherapy or other chemotherapy after disease progression; b) Patients who have received other EGFR TKI targeted therapy after disease progression; c) Patients who have received chest radiotherapy after disease progression; d) Patients who have received any lung cancer immunotherapy after disease progression; e) Patients who have received anti-angiogenic drugs such as bevacizumab after disease progression; f) Patients who have received major surgery (including biopsy) or major trauma within 4 weeks before the first administration of the study drug; Patients who are expected to require major surgery during the study; g) Patients who have received more than 30% bone marrow irradiation or large-area radiotherapy within 4 weeks before the first administration of the study drug; i) Patients who have used strong CYP3A4 inhibitors, inducers, or drugs with narrow therapeutic windows that are sensitive substrates of CYP3A4 within 7 days before the first administration of the study drug.
• Patients with only local recurrence and who are suitable for radical chest radiotherapy and chemotherapy.
• Patients with any complications or other malignancies who require standard treatment or major surgery within 2 years after the first administration of study treatment.
• Severe cardiovascular and cerebrovascular diseases, including but not limited to cerebrovascular accident (CVA), transient ischemic attack (TIA), myocardial infarction, unstable angina, heart failure ≥ grade II (New York Heart Association (NYHA) classification) within 6 months before enrollment, and severe arrhythmias (including: requiring drug control during the study; the drugs used will interfere with the normal treatment of the study drugs; arrhythmias that cannot be controlled by drugs).
• A history of interstitial lung disease, a history of drug-induced interstitial lung disease, a history of radiation pneumonitis requiring steroid treatment, or any evidence of clinically active interstitial lung disease.
• Non-healing wounds, active peptic ulcers, or fractures.
• Patients with other malignancies other than non-small cell lung cancer within 5 years before enrollment, excluding fully treated cervical carcinoma in situ, basal cell or squamous cell skin cancer, localized prostate cancer after radical surgery, and breast ductal carcinoma in situ.
• Patients with residual toxicity from previous treatment that was greater than CTCAE grade 1 and failed to be relieved at the start of study treatment, excluding those with alopecia and grade 2 neurotoxicity caused by previous chemotherapy.
• Spinal cord compression or brain metastasis, unless asymptomatic, stable, and without the need for steroid treatment for at least 2 weeks before the first dose of study treatment.
• Patients with any severe or poorly controlled systemic disease, such as active bleeding physique or active infection, as judged by the investigator. Chronic diseases do not need to be screened.
• Patients with refractory nausea, vomiting, or chronic gastrointestinal diseases, inability to swallow study drugs, or previous extensive intestinal resection may affect the adequate absorption of osimertinib.
• Meet any of the following cardiac examination results:
• The average corrected QT interval (QTc) obtained from 3 electrocardiograms (ECG) at rest is \> 470 msec, and the QT interval correction (QTcF) is performed using the Fridericia formula;
• The resting ECG shows various clinically significant rhythm, conduction or ECG morphology abnormalities (such as complete left bundle branch block, third-degree atrioventricular block, second-degree atrioventricular block and PR interval \> 250 msec);
