The aim of this study is to determine if paclitaxel given together with ramucirumab (IMC-1211B) as second line therapy will prolong overall survival (OS) compared to paclitaxel alone.~Approximately 663 participants (at least 18 years) in approximately 200 study centers and in approximately 30 countries will be randomized with histologically or cytologically confirmed metastatic gastric or gastroesophageal junction adenocarcinoma. Participants must have received at least one cycle of first line therapy with any platinum/fluoropyrimidine doublet with or without anthracycline (epirubicin or doxorubicin) and must have discontinued this therapy prior to study entry due to disease progression.~Upon registration and completion of screening procedure and reviewing the Inclusion and Exclusion Criteria eligible participants will be randomized to receive either paclitaxel plus ramucirumab or paclitaxel plus placebo.~Ramucirumab (IMC-1211B) DP/placebo will be administered IV on Days 1 and 15, paclitaxel will be administered IV on Days 1, 8 and 15 of a 4 weekly cycle.~Participants will be continuously treated and monitored until radiographic or symptomatic progression of disease, toxicity requiring cessation, protocol noncompliance, or withdrawal of consent.
This is a Phase III randomized multicenter double-blind, placebo controlled trial evaluating the safety and efficacy of paclitaxel plus ramucirumab (IMC-1211B) drug product (DP) compared to paclitaxel plus placebo.
