You may be eligible if
Eastern Cooperative Oncology Group (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 version 1.1)
Adequate organ function as determined by the following laboratory results, within 28 days prior to randomization
Participants 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)
Participants 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.
You may not be if
An interval shorter than 21 days from the last dose of chemotherapy or HER2-directed therapy until the time of randomization
Prior treatment with trastuzumab emtansine, docetaxel, or paclitaxel either as single agents or as part of a treatment regimen.
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
