Introduction: Gastric cancer remains one of the most lethal malignancy, accounting for an estimated 783,000 deaths worldwide in 2018. Although there are several approved drugs for the treatment of gastric cancer, the survival of patients with advanced disease remains dismal. Ramucirumab, a vascular endothelial growth factor receptor-2 inhibitor, is an important new targeted drug approved for gastric and gastroesophageal adenocarcinoma (GEJ) in second-line setting. Areas covered: In this article, we have reviewed the role of ramucirumab in the management of gastric and GEJ adenocarcinoma. A comprehensive review of various clinical trials is presented that support the use of ramucirumab in gastric cancer. Expert opinion: In our opinion, ramucirumab should be considered as a standard of care option, either alone or with paclitaxel, after progression on first-line therapy for advanced or metastatic disease. The results of large, randomized phase III clinical trials show benefit of ramucirumab on median overall survival (OS). However, the benefit is limited, with only about two months OS benefit of using ramucirumab with paclitaxel compared to paclitaxel alone. Novel combination therapies, such as ramucirumab with other targeted agents and immune checkpoint inhibitors in ongoing clinical trials, may provide important information to further improve the patient outcomes.
