Brief summary: This study is conducted to explore the safety and efficacy of anlotinib, a tyrosine kinase inhibitors of vascular endothelial growth factor receptor 2（VEGFR）、FGFR（fibroblast growth factor receptor）, platelet-derived growth factor receptor（PDGFR） and tumor cell proliferation related kinase c-Kit, combined with platinum plus pemetrexed in T790M mutation negative metastatic non-squamous non-small cell lung cancer(NSCLC) after the failure of EGFR-TKI.

Detailed description: Anlotinib, an oral highly potent tyrosine-kinase inhibitor targeting VEGFR、PDGFR、FGFR and c-kit，has demonstrated improved survival in previously treated patients with advanced non-small-cell lung cancer(NSCLC).

In the phase Ⅲ study ALTER0303, patients who failed at least two kinds of systemic chemotherapy (third line or beyond) or drug intolerance were treated with anlotinib or placebo, the anlotinib group PFS and OS were 5.37 months and 9.63 months, the placebo group PFS and OS were 1.4 months and 6.3 months. Therefore,we envisage using anlotinib plus platinum plus pemetrexed treat the EGFR wild-type metastatic non-small cell lung cancer patients who were failure in the treatment of chemotherapy with platinum containing drugs, to further improve the patient's PFS.

The study is divided into two stages，phase I use a dose escalation trial design to explore the safety, tolerability, dose-limiting toxicities(DLT), Maximum Tolerable Dose(MTD), A cohort of 3\~6 subjects will be enrolled at each dose level, If 0 of 3 or ≤ 1 of 6 subjects experience a DLT, the phase I trial will move ahead to the next dose until ≥ 2 of 6 subjects experience a DLT，and the current dose will be considered the MTD. Following completion of the dose escalation trial and determination of MTD（Phase I）, a single arm study including 44 subjects may be enrolled to further evaluate safety, tolerability, and efficacy of anlotinib in combination with platinum plus pemetrexed in the same target population（phase II）. Phase II is to designed to explore the anti-tumor activity of anlotinib combined with platinum plus pemetrexed in T790M mutation negative metastatic non-squamous non-small cell lung cancer(NSCLC) after the failure of EGFR-TKI.
