NCT06477055

Brief Summary

This study was a multicenter, real-world observational study aimed at characterizing the genomic landscape of recurrence in patients with EGFR-sensitizing mutation-positive early-stage (clinical stage IB-IIIA) non-small cell lung cancer who received adjuvant osimertinib after surgery.

Outcome Measures

Primary Outcomes (1)

  • Recurrence gene profiles

    To assess the recurrence gene profiles of adjuvant Osimertinib therapy

    From April 1, 2021 to May 31, 2025, assessed retrospectively from medical records.

Secondary Outcomes (2)

  • Recurrence gene profiles in patients with different recurrence types (local /distant)

    From April 1, 2021 to May 31, 2025, assessed retrospectively from medical records

  • Subsequent treatment patterns

    From April 1, 2021 to May 31, 2025, assessed retrospectively from medical records

Other Outcomes (1)

  • Investigate the mechanisms driving tumor progression

    From April 1, 2021 to May 31, 2025, assessed retrospectively from medical records.

Study Arms (2)

Cohort 1

consists of 30 patients who experienced a recurrence more than 6 months after completing 3 years of adjuvant osimertinib.

Cohort 2

consists of 30 patients with recurrence during adjuvant osimertinib treatment.

Study Population

This multicenter, retrospective, real-world study includes patients with resected stage IB-IIIA NSCLC harboring EGFR-sensitizing mutations (exon 19 deletion or exon 21 L858R) who received adjuvant osimertinib. A total of 60 patients are enrolled and classified into two cohorts based on recurrence timing: Cohort 1 comprises 30 patients with recurrence more than 6 months after completing 3 years of adjuvant osimertinib; Cohort 2 comprises 30 patients with recurrence during adjuvant osimertinib treatment. Genomic profiling data of recurrence, obtained from next-generation sequencing of tissue and/or blood samples, are collected and analyzed. All data are extracted from electronic medical records.

You may qualify if:

  • Informed consent signed;
  • Age ≥ 18 years;
  • Histologically confirmed diagnosis of non-squamous non-small cell lung cancer;
  • Patients with stage IB-IIIA (TNM 8#) NSCLC undergo confirmed radical R0 resection;
  • Confirmed EGFR sensitive-mutations (exon 19 deletions, 21 L858R point mutations) prior to adjuvant osimertinib therapy;
  • Recurrence after/on Osimertinib treatment according to RECIST 1.1;
  • NGS gene test report (tumor or blood sample) at the time of recurrence;
  • Receiving or not receiving neoadjuvant treatment before surgery.

You may not qualify if:

  • Patients with stage I-III NSCLC whose surgical resection cannot be confirmed;
  • Received adjuvant therapy other than that specified in the ADAURA study;
  • No NGS test report at recurrence;
  • History of other malignant tumors within 2 years;
  • Patients assessed by the investigator as unfit for enrollment, such as neurological disorders or metabolic disorders, physical examination or laboratory examination suspected that the patient has a possible disease, or has treatment-related complications High risk etc.
