Evaluate the efficacy and safety of Anlotinib in combination with Docetaxel versus Docetaxel in patients with advanced non-small lung cancer after failure of first-line Chemotherapy .

Anlotinib is a multi-target receptor tyrosine kinase inhibitor in domestic research and development. It can inhibit the angiogenesis related kinase, such as VEGFR, FGFR, PDGFR, and tumor cell proliferation related kinase -c-Kit kinase. In the phase Ⅲ study, patients who failed at least two kinds of systemic chemotherapy (third line or beyond) or drug intolerance were treated with anlotinib（12mg，po. qd. on day 1to14 of a 21-day cycle） 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, the investigators envisage using anlotinib plus docetaxel treat the advanced Non-small cell lung cancer patients who were failure of first-line Chemotherapy , to further improve the patient's PFS.
