Introduction: Anlotinib hydrochloride is a multi-targeted receptor tyrosine kinase inhibitor that targets angiogenesis-related kinases and has already showed good safety and efficacy in some solid tumours. However, evidence on the safety and feasibility of anlotinib in patients with stage IV gastric cancer is scarce.
Methods and analysis: This study is a single-armed and single-centred clinical study being designed to include 150 patients of stage IV gastric cancer. The patients' demographics, pathological characteristics, test results of blood, biochemistry and tumour markers before and after medication, disease-free survival and overall survival will be collected and analysed. The primary and main efficacy outcomes are objective response rate, progression-free survival, disease control rate and overall survival. The secondary efficacy outcome is safety indicator including the incidence of adverse drug reactions and adverse events after administration.
Ethics and dissemination: Ethics approval has been obtained from the Ethics Committee at the First Affiliated Hospital (Xijing Hospital) of Fourth Military Medical University (KY20192111-F-1). The results of this study will be disseminated at several research conferences and as published articles in peer-reviewed journals.
