You may be eligible if
1. According to the 8th edition of the AJCC/UICC TNM staging system for NSCLC, patients with locally advanced (stage III B/III C), metastatic or recurrent (stage IV) NSCLC confirmed by histology or cytology who are unable to undergo surgery and radical concomitant radiochemotherapy and are confirmed to have at least one measurable lesion according to RECIST 1.1.
2. Patients harboring uncommon EGFR mutations. Uncommon EGFR mutations were defined as mutations in exon 18-21 but except for 19del, 21L858R and well-established drug resistant type (20 insertion, 20T790M, 19L747S, 19L747P, D761Y, 21T854A). Mutations should be previously reported that it was sensitive to first- or second-generation TKIs. Detailed mutation type including:
Few exon 19 point mutations with unknown structure and kinase activity have been found in EGFR-TKI responders, however, a new class of sensitizing mutations, exon 19 insertions, were recently found, these patients were also eligible for this study: I744\_K745insKIPVAI, K745\_E746insIPVAIK, K745\_E746insVPVAIK, K745\_E746insTPVAIK.
5. Previously untreated with EGFR-TKIs including first-, second- or third generation agents. Subjects who were only treated with chemotherapy were eligible. Patients who have received adjuvant chemotherapy but disease recurrence must have happened at least 6 months after the last dose of chemotherapy. Palliative radiotherapy must be completed 7 days before the first dose of study drugs;
6. The main organs function is normal, that is, the following criteria met:
* Good hematopoietic function, defined as absolute neutrophil count ≥1.5×109 /L, platelet count≥100 ×109 /L, hemoglobin ≥90g/L \[no blood transfusion or no erythropoietin (EPO) dependence within 7 days before enrollment\]
* Biochemical test results should meet the following criteria: BIL \< 1.25 times the upper limit of normal value (ULN); ALT and AST \< 2.5 × ULN; in case of liver metastases, ALT and AST \< 5 × ULN; Cr ≤1.5×ULN or creatinine clearance (CCr) ≥60ml/min; Coagulation function is good, INR and PT ≤1.5 times ULN; if the subject is receiving anticoagulant treatment, PT should be within the prescribed range of use of anticoagulant drugs;
7. Women of child-bearing age should agree to take contraceptive measures (such as intrauterine devices, contraceptives or condoms) during the study and within 6 months after the study; non-breast-feeding patients whose serum or urinary pregnancy test should be negative; male patients should agree to take contraceptive measures during the study and within 6 months after the study.
8. Patients are voluntarily enrolled into the study, sign the informed consent form and have good compliance.
Patients who meet any of the following criteria will be excluded:
1. Small cell lung cancer (including mixed small cell and non-small cell lung cancer);
2. Patients who have received EGFR-TKIs as adjuvant or salvaged treatment;
3. Patients with 19del or 21L858R or well-established drug resistant type (20 insertion, 20T790M, L747S, L747P, D761Y, T854A).
4. Patients with many factors affecting oral medication, such as dysphagia, gastrointestinal resection, chronic diarrhea and intestinal obstruction;
5. Patients who are known to have brain metastases including asymptomatic metastasis, spinal cord compression, carcinomatous meningitis, or brain or leptomeningeal disease diagnosed by CT or MRI at the time of screening;
6. Patients with severe and / or uncontrolled diseases, such as:
* Routine urine test result indicates that urine protein ≥++, and 24-hour urine protein quantitation is confirmed to be \> 1.0 g;
* Active tuberculosis, etc.;
* Uncontrolled hypercalcemia (\> 1.5 mmol/L calcium ion or calcium \> 12 mg/dL or corrected serum calcium \> ULN), or symptomatic hypercalcemia requiring continued diphosphate therapy;
* Long-term unhealed wounds or fractures;
7. Patients who have a history of psychotropic drug abuse and cannot abstain from it or have mental disorders;
8. Patients who are known to have severe allergies (≥ grade 3) to active ingredients and any excipients of dacomitinib
9. Patients who have other malignant tumors (except radical cervical carcinoma in situ, non-melanoma skin cancer, etc.) at the same time; patients who are evaluated by the investigator to have concomitant diseases that seriously endanger the safety of the patients or affect the patients completing the study.
10. The subjects or their sexual partners cannot or refuse to take effective contraceptive measures during the clinical trial
11. Pregnant or breast-feeding women
12. Patients in other situations who are evaluated by the investigator to be ineligible to be enrolled
