Trastuzumab in Combination with Different First-Line Chemotherapies for Treatment of Her2-Positive Metastatic Gastric Cancer: Updated Findings from the German Non-Interventional Study Hermes

ABSTRACT Aim: The international phase III study ToGA has shown that trastuzumab (TRA) (Herceptin®) is effective in prolonging survival in HER2-positive metastatic gastric or gastro-oesophageal junction cancer (MGC). However, few data are available for TRA as part of routine clinical practice. Methods: This non-interventional observational study (NCT01220934) aims to evaluate the efficacy, safety and feasibility of TRA in previously untreated pts with HER2-positive MGC. Results: Between Apr 2010 and Apr 2014, we collected data from 360 pts. All pts were evaluable for safety. Baseline pt characteristics were as follows: median age 66 y (range 29–90); gender (male 74%; female 26%); ECOG PS (0:…
