Participants should have received only 1 line of platinum-containing treatment for metastatic disease (i.e., adjuvant treatment with a platinum-containing regimen is not sufficient for eligibility because not received in the context of a metastatic disease).

Participants who received any platinum containing doublet or triplet as a neoadjuvant chemotherapy strategy, but are not ultimately candidates for surgery will also be eligible, as long as they did not have progressive disease after completion of the neoadjuvant chemotherapy. In addition, participants with gastric cancer can enter in the study if their white blood cell (WBC) and lymphocyte count is as defined in the protocol
