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 c-kit, vs docetaxel in advanced Non-squamous Non-small cell lung cancer harbouring wild-type epidermal growth factor receptor (EGFR) .

This is a multicentre randomised controlled clinical trial conducted in China to compare the efficacy and and safety of Anlotinib vs Docetaxel in patients of EGFR mutation-negative advanced nonsquamous non-small Cell Lung Cancer.

Eligible patients will be randomized to arm A and arm B:

Arm A: Patients on the anlotinib arm received 12mg anlotinib orally daily on day 1 to 14 of a 21-day cycle.

Arm B: Patients on the docetaxel arm received 75mg/m2 docetaxel as intravenous infusion on day 1 of a 21-day cycle.
