Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Based on the existing research results, Osimertinibi is effective not only for patients with sensitizing EGFR mutations, but also for other less common EGFR mutations. However, no studies have been done so far regarding the difference in efficacy of various EGFR mutation subtypes. Meanwhile, the presenting studies data of the safety and efficacy of Osimertinib as first-line therapy for NSCLC is very limited. Therefore, this study aims at assessing the safety and efficacy of Osimertinib as First-line therapy for patients with EGFR mutation-positive locally advanced or Metastatic Non-squamous NSCLC as well as the its difference in efficacy of various EGFR mutation subtypes.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Histologically or cytologically confirmed unresectable locally advanced(Stage IIIB，not amenable to definitive multi-modality therapy)、metastatic(Stage IV)or recurrent EGFR mutation-positive Non-squamous NSCLC.( Diagnosis of NSCLC based on sputum cytology alone is not acceptable; If the specimen shows more than one tumor components, a pathological evaluation to classify the major histological subtype of the lung cancer must be performed.)Choose EGFR-TKIs as the first-line therapy.
2. Patients with EGFR mutation(any form of EGFR mutation subtype except for EGFR exon 20 insertion mutation) detected by First generation sequencing(Sager sequencing) or next generation sequencing(NGS) from tissue sample includes fresh tissue or formalin-fixed paraffin-embedded(FFPE)sample or body fluid sample(blood, pleural effusion, cerebrospinal fluid ,etc.)
3. Measurable disease by RECIST 1.1(At least one lesion that can be accurately measured at baseline as ≥10mm in the longest diameter, If the CT scan thickness \>5mm, the lesion diameter is at least 2 times the scan thickness).
4. Age≥18 years or≤75 years.
5. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS)of 0 or 1.

8. Adequate hepatic function:Total bilirubin \< 1.5 x upper limit of normal(ULN);For patients without liver metastases:Aspartate aminotransferase (AST)/ alanine aminotransferase (ALT) \<2.5 x ULN;For patients with known hepatic metastases AST and ALT both \<5 x ULN.
9. Adequate renal function:Serum Creatinine≤1.5x ULN or creatinine clearance≥50mL/min;
10. Within 7 days before included in the study:International normalized ratio(INR) ≤1.5, prothrombin time(PT) or activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN.
