Study of Ramucirumab, Trastuzumab and Paclitaxel in Patients With HER2-positive Recurrent/Metastatic Gastric Cancer (HER-RAM Study)

An Open-label, Multicenter Phase Ib/II Study of Ramucirumab in Combination With Trastuzumab and Weekly Paclitaxel in Patients With HER2-positive Recurrent/Metastatic Gastric Cancer

Human epidermal growth factor receptor 2 (HER2) is overexpressed or amplified in 10-20% of gastric or gastroesophageal junction cancer. Trastuzumab combined with fluorouracil and platinum has been established as first-line treatment for patients with HER2-positive gastric cancer. The role of trastuzumab in second-line treatment for HER2-positive gastric cancer has not yet been addressed. Here, we evaluated the safety and efficacy of adding trastuzumab to ramucirumab and paclitaxel combination as a second-line treatment in HER2-positive gastric cancer progressed after trastuzumab-containing chemotherapy.
