This single-arm, open, multicenter clinical study is going to evaluate the efficacy and safety of combination therapy with ectiecinib, pemetrexed and platinum in patients with metastatic non-squamous non-small cell lung cancer with EGFR mutations who did not progress after pemetrexed in combination with platinum-based chemotherapy.


The positive rate of EGFR mutations in lung adenocarcinoma patients is about 50% in both Asian population and China.Domestic and international clinical studies have found that targeted therapy combination chemotherapy can prolong the overall survival of patients with EGFR mutations, and a large number of class 2A evidences have been recommended.The 2018 CSCO lung cancer guidelines recommend EGFR-TKIs combined with chemotherapy for first-line treatment of advanced EGFR mutant NSCLC (grade II recommended).The independently developed ectinib in China, belong to EGFR-TKIs as gefitinib and erlotinib . The results of phase III clinical trial (ICOGEN) showed that the efficacy of ectinib and gefitinib was similar, but in terms of safety, the adverse reactions of the ectinib group were significantly lower than that of the gefitinib group, and the difference between the two groups was statistically significant.Targeted combination chemotherapy has relatively large side effects, which will increase chemotherapy-related side effects, mainly hematological toxicity. Foreign studies suggest that combination therapy may be more suitable for patients with good basic state.Based on previous studies, this study is going to use the strategy of short-term induction chemotherapy and drug sensitivity platform to find the most suitable patients for combined therapy.

This single-arm, open, multicenter clinical study is going to evaluate the efficacy and safety of combination therapy with ectiecinib, pemetrexed and platinum in patients with metastatic non-squamous non-small cell lung cancer with EGFR mutations who did not progress after pemetrexed in combination with platinum-based chemotherapy.

Patients received two cycles of chemotherapy with pemetrexed/platinum before enrolling, followed by ectinib: ectinib 125mg/ tablet, one tablet at a time, three times a day, take orally, until disease progression;Pemetrexed 500mg/m2, intravenously administered on day 1;Carboplatin AUC6/ Cisplatin 75mg/m2,intravenously on day 1,21 days for a cycle, a total of 6 cycles.Maintenance therapy: ectinib: ectinib 125mg/ tablet, one tablet at a time, three times a day, take orally, pemetrexed 500mg/m2, intravenously on day 1,21 days for a cycle, until disease progression.Make detailed records of toxic and side effects during medication.The efficacy was evaluated using RESIST standard after every 2 cycles of the treatment, the regimen will continue until the disease progression or the appearance of not tolerable toxicity.

Received two cycles of pemetrexed/platinum chemotherapy with no progress (efficacy was evaluated as SD or PR)
Tumor specimens must be provided before patients receive ectinib combined chemotherapy to complete the EGFR gene test. There is no need to clarify the EGFR mutation status before the initial pemetrexed/platinum chemotherapy
Volunteers who participate in exploratory studies need provide tumor samples for the laboratory to complete the study on anti-tumor drug sensitivity of microfluidic chip technology
Volunteers who participate in exploratory studies need provide blood samples to complete the analysis of blood biomarkers and disease progression/anti-tumor efficacy, tolerance and safety of drugs
0-1 ECOG score
Patients may have a history of brain parenchymal metastasis, and local treatment (surgery and/or radiotherapy) is required for good control of symptoms, and hormone maintenance therapy is not required
According to RECIST criteria 1.1, there is at least one measurable lesion that has not been irradiated:1) if there is at least one measurable lesion, and if there is only one lesion, the nature of new organisms at the lesion site must be confirmed by cytology or histology;2) for patients with at least one lesion diameter that can be accurately measured by any of the following methods, computed tomography (CT) or magnetic resonance (MRI) of chest or abdomen, the diameter of which should be at least 20mm by conventional methods or at least 10mm by spiral CT
The level of organ function must meet the following requirements:1) bone marrow: median granulocyte absolute count (ANC) 1.5109/L, platelet 100109/L, hemoglobin 9 g/dL;2) liver: serum bilirubin 1.5 times the upper limit of normal value, aspartate aminotransferase (AST) and alanine aminotransferase (ALT)2.5 times the upper limit of normal value (ALT 5 times the upper limit of normal value if there is liver metastasis);3) upper limit of serum creatinine <1.5 times normal value;Creatinine clearance 50 mL/min (calculated by cockroft-gault10 formula) for patients with low body weight or patients with significantly different values calculated by the two formulas, it is recommended to measure creatinine clearance by other methods, such as EDTA method, inulin clearance method, or 24-hour urinalysis.4) international standardized ratio of prothrombin time (INR) 1.5 and partial thrombin time (APTT) 1.5 upper limit of normal value in patients who have not received anticoagulation therapy.Patients receiving full or parenteral anticoagulant therapy can enter the clinical trial as long as the dose of anticoagulant is stable for at least 2 weeks before entering the clinical study and the results of coagulation test are within the limits of local treatment
Women of reproductive age must have negative serum pregnancy test results within 7 days prior to treatment;All enrolled patients (male or female) should take adequate barrier contraception during and within 4 weeks after treatment
Patients must be able to understand and sign informed consent voluntarily, prior to any trial procedures
