• Adult patients, aged >/= 18 years.
• ECOG performance status of 0 or 1.
• Life expectancy of at least 12 weeks from the first dose of study treatment.
• Measurable and/or evaluable disease based on Response Evaluation Criteria in Solid Tumors (RECIST v1.1).
• Adequate organ function as determined by the following laboratory results, within 28 days prior to randomization.
• Patients must have a history of advanced gastric cancer (AGC), defined as unresectable and locally advanced or metastatic gastric cancer, including adenocarcinoma of the gastroesophageal junction (GEJ), and must have experienced disease progression during or after first-line therapy for their disease.
• HER2-positive tumor (primary tumor or metastatic lesion) as confirmed by central laboratory HER2 testing (immunohistochemistry and/or in-situ hybridization).
• Patients must have received at least one prior chemotherapy regimen for AGC; prior therapy does not need to have included HER2-directed therapy.
• First-line therapy for AGC, including adenocarcinoma of the GEJ, must have included a combination of at least a platinum- and a fluoropyrimidine-based treatment given concurrently; prior therapy does not need to have included a HER2-directed therapy.
• Adjuvant or neoadjuvant therapy for AGC is allowed.
• Women of childbearing potential and men with partners of childbearing potential must be willing to use a highly effective, non-hormonal form of contraception or two effective forms of contraception by the patient and/or partner and continue its use for the duration of study treatment and for 7 months after the last dose of study treatment.

• Treatment with any investigational anticancer drug within 21 days of the first study treatment administration.
• More than one prior line of therapy for advanced gastric cancer.
• History of other malignancy within the previous 5 years except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, Stage I uterine cancer, or other malignancies with an expected curative outcome.
• Brain metastases that are untreated or symptomatic or require any radiation, surgery, or steroid therapy to control symptoms from brain metastases within 1 month of randomization.
• Peripheral neuropathy Grade >/=2.
• Uncontrolled cardiopulmonary dysfunction (e.g., high blood pressure, serious cardiac arrhythmia).
• Other current, severe, uncontrolled systemic disease (e.g., clinically significant metabolic disease, wound healing disorders, ulcers).
• Clinically significant bleeding within 30 days before enrollment.
• For female patients, current pregnancy or lactation.
• Major surgical procedure or significant traumatic injury within 28 days prior to randomization or anticipation of the need for major surgery during the course of study treatment.
• Infection with HIV or hepatitis B virus, hepatitis C virus.

Name Time Method Main Objective: To compare the overall survival (OS) of patients treated with trastuzumab emtansine with the regimen from Stage 1 of the study selected at the interim analysis to the OS of patients treated with physician’s choice of taxane (docetaxel or paclitaxel) in patients with HER2-positive advanced gastric cancer (AGC), defined as unresectable and locally advanced or metastatic GC, including adenocarcinoma of the GEJ. <br>;Secondary Objective: • Objective response rate (ORR)<br>• Progression-free survival (PFS) <br>• Duration of response (DOR) <br>• Characterization of clinical safety<br>• Assessment of Quality of Life<br>;Primary end point(s): Overall Survival (OS);Timepoint(s) of evaluation of this end point: Approximately 3 years
