The purpose of this study is to determine the safety and effectiveness of a combination of chemotherapy, capecitabine and oxaliplatin, plus the antibodies bevacizumab and trastuzumab. Trastuzumab (also called Herceptin) is an antibody that attacks HER2 protein in tumor cells. Bevacizumab (also called Avastin) works by slowing or stopping the growth of cells in cancer tumors by decreasing the blood supply of the tumors. If blood supply is decreased, oxygen and nutrients that are needed for tumor growth are decreased. The chemotherapy used in this trial is called CAPOX, which is an abbreviation of capecitabine and oxaliplatin.

- We recommend that the participants have a vascular access device, more commonly known as a PORT, inserted prior to starting chemotherapy. A port is a small device that is inserted under the skin (usually near the collar bone) by a minor surgical procedure and is then connected to one of the large veins inside the chest. The port will be used to give the intravenous medications.
- During the first cycle, the participant will receive trastuzumab intravenously on Day 1. Cycle 2 will then start one week later. On this day, bevacizumab will be given intravenously first followed by trastuzumab and then oxaliplatin. The participant will then start taking capecitabine tablets orally twice a day for 14 days. Each treatment cycle is 21 days long.
- Participants will have the following tests and procedures at specific time points during study treatment; physical exam, blood tests, CT scan, MUGA scan or echocardiogram, and urine test.
