Brief summary: To evaluate the efficacy and safety of recombinant human endostatin (Endostar) combined with platinum-based doublet chemotherapy as the first-line therapy for patients with driver-gene-negative advanced non-small cell lung cancer(NSCLC).

This study is an exploratory single-arm study. The specific treatment regimen is as follows: Non-squamous NSCLC: Endostar (210 mg, continuous intravenous infusion (CIV) for 120 h) is started on the first day of each treatment cycle and administered every three weeks. Carboplatin AUC 5-6 mg/ml/min or cisplatin 75 mg/m2 (d4) +pemetrexed 500 mg/m2 (d4) Q3W is administered in this regimen for 4 cycles followed by Endostar plus pemetrexed until disease progression or intolerable toxicity.

Squamous NSCLC: Endostar (210 mg, continuous intravenous infusion (CIV) for 120 hours) is started on the first day of each treatment cycle and administered every three weeks. Carboplatin AUC 5-6 mg/ml/min or cisplatin 75 mg/m2 (d4) + paclitaxel 175 mg/m2 (d4) Q3W.Endostar is administered after 4 cycles of this treatment regimen until disease progression or intolerable toxicity developed.

Patients are assessed for measurable disease at baseline, 6 weeks, 12 weeks after starting treatment, and every 9 weeks thereafter according to RECIST 1.1 criteria during the treatment period until disease progression or intolerable toxicity withdrawal. Following discontinuation of treatment, subjects are followed for survival status every 3 months until death. Subject safety was assessed during treatment according to NCI CTCAE Version 4.0 criteria. Subjects who experience an AE should be followed until the AE returns to baseline. The primary endpoints is Progression-free survival (PFS) . Secondary endpoints include objective response rate (ORR), overall survival (OS) and safety (NCI CTCAE v 4.0).

Statistical methods: The PFS curve was estimated using the Kaplan-Meier method for the largest population to be analyzed. The confidence interval method was used as the criterion for the main analysis. OS was calculated in the same way as the secondary endpoint. Descriptive statistics will be used to analyze ORR, DCR, etc.

It is expected that continuous intravenous Endostar combined with platinum-based doublet chemotherapy as first-line treatment will prolong median PFS and OS in patients with driver gene-negative advanced NSCLC.

Detailed description: With the progress of molecular biology and translational medicine research, the treatment of advanced non-small cell lung cancer(NSCLC) has entered the era of individualized treatment. EGFR-TKIs bring about 2 years of overall survival (OS) to patients with EGFR mutated advanced non-small cell lung cancer, and ALK mutations are also promising. For patients with lung cancer whose EGFR and ALK mutations are -negative or unknown, chemotherapy remains the mainstay of treatment. Platinum-based chemotherapy entered the plateau of efficacy.

The occurrence of tumor vessels depends on the activation, proliferation, adsorption and maturation process of vascular endothelial cells, all of which can be the target of vascular inhibitors. Recombinant human endostatin (Endostar) can inhibit tumor endothelial cell proliferation, angiogenesis and tumor growth. Endostar has been shown to be efficient and safe in the treatment of NSCLC and was approved by Chinese Food and Drug Administration. Endostar combined with platinum-based chemotherapy in non-small cell lung cancer has shown high safety and efficacy, with encouraging clinical application prospects. Endostar is currently administered in clinical application at 7.5 mg/m2 by instillation for 3 - 4 hours per day for 14 consecutive days as a cycle. Because its half-life is only about 10 hours, it will cause excessive fluctuations in plasma concentrations in the body and inability to maintain steady-state concentrations, while the patient 's compliance is also poor. Continuous intravenous infusion of Endostar can maintain steady-state plasma concentration and continuously inhibit tumor angiogenesis without increasing the toxicity of the drug, further improving the efficacy of Endostar and patient compliance. Although very low quality of evidence supported the survival benefit of continuous intravenous compared with intermittent intravenous, we need more evidence to demonstrate survival benefits.

Objective: To evaluate the efficacy and safety of Endostar(210 mg, continuous intravenous infusion(CIV) for 120h) combined with platinum-based doublet chemotherapy as the first-line therapy for patients with driver-gene-negative advanced NSCLC.

The research idea starts from the safety and efficacy of Endostar in vascular targeted therapy for lung cancer. Under the theoretical perspective of clinical research on cancer treatment, an exploratory multicenter single-arm study method is used to perform Endostar (210 mg, CIV 120h) combined with platinum-based chemotherapy regimen for first-line treatment of advanced NSCLC patients with negative driver gene. A database is established for the enrolled case report form, systematic data analysis is performed, and finally the study conclusions of Endostar safety, efficacy, timing method and optimization are obtained. It is expected that continuous intravenous Endostar combined with platinum-based doublet chemotherapy as first-line treatment will prolong median PFS and OS in patients with driver gene-negative advanced NSCLC.

This study is an exploratory single-arm study. The specific treatment regimen is as follows: Non-squamous NSCLC: Endostar (210 mg, CIV for 120 h) is started on the first day of each treatment cycle and administered every three weeks. Carboplatin AUC 5-6 mg/ml/min or cisplatin 75 mg/m2 (d4) +pemetrexed 500 mg/m2 (d4) Q3W is administered in this regimen for 4 cycles followed by Endostar plus pemetrexed until disease progression or intolerable toxicity.

Squamous NSCLC: Endostar (210 mg, CIV for 120 hours) is started on the first day of each treatment cycle and administered every three weeks. Carboplatin AUC 5-6 mg/ml/min or cisplatin 75 mg/m2 (d4) + paclitaxel 175 mg/m2 (d4) Q3W.Endostar is administered after 4 cycles of this treatment regimen until disease progression or intolerable toxicity developed.

Patients are assessed for measurable disease at baseline, 6 weeks, 12 weeks after starting treatment, and every 9 weeks thereafter according to RECIST 1.1 criteria during the treatment period until disease progression or intolerable toxicity withdrawal. Following discontinuation of treatment, subjects are followed for survival status every 3 months until death. Subject safety was assessed during treatment according to NCI CTCAE Version 4.0 criteria. Subjects who experience an AE should be followed until the AE returns to baseline.The primary endpoints is Progression-free survival (PFS) . Secondary endpoints include objective response rate (ORR), overall survival (OS) and safety (NCI CTCAE v 4.0).

Statistical methods: The PFS curve was estimated using the Kaplan-Meier method for the largest population to be analyzed. The confidence interval method was used as the criterion for the main analysis. OS was calculated in the same way as the secondary endpoint. Descriptive statistics will be used to analyze ORR, DCR, etc.
