A Trial of Anlotinib Combined With Docetaxel in Patients With Wild-type Advanced Non-squamous Non Small Cell Lung Cancer

A Study on the Efficacy and Safety of Anlotinib Combined With Docetaxel in the Treatment of Wild-type Advanced Non-squamous Non Small Cell Lung Cancer Patients With Progress After Immunotherapy Plus Chemotherapy as First-line Treatment

Anlotinib is a multi-target receptor tyrosine kinase inhibitor under domestic research and development. It can inhibit angiogenesis-related kinases, 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 systemic chemotherapy (third-line or above) or were intolerant of the drugs were treated with anlotinib or placebo. The PFS and OS in the anlotinib group were 5.37 months and 9.63 months, respectively. The placebo group PFS and OS were 1.4 months and 6.3 months. Therefore, it is envisaged to use anlotinib combined with docetaxel to treat wild-type advanced non-squamous non small cell lung cancer to further improve the patient's PFS or OS.

This is a single arm clinical trial conducted in China. The purpose of this study is to assess the efficacy and safety of Anlotinib Hydrochloride (12mg, QD PO d1-14, 21days per cycle) combined with Docetaxel (75mg/m2 IV d1) in the treatment of wild-type advanced non-squamous non small cell lung cancer patients with progression after immunotherapy plus chemotherapy as first-line treatment. After being informed about the study and potential risks, all patients giving written informed consent will undergo a 4-week screening period to determine eligibility for study entry. The expected sample size is 42.
