apatinib plus docetaxel as 2nd line treatment in patients with advanced lung adenocarcinoma harboring wild-type egfr

Conditions: Lung Adenocarcinoma

Summary: the purpose of this study is to confirm the safety of apatinib at a dose level up to 750 mg/d with standard therapy of docetaxel (60 mg/m²) in advanced lung adenocarcinoma patients harboring wild-type egfr after failure of first line chemotherapy and to determine the recommended dose for the phase ii trial.
