Inclusion Criteria

1. Patients (>18yr) with histologically or cytologically confirmed diagnosis of breast cancer, or patients with documented cytologically or histologically confirmed gastric adenocarcinoma or gastroesophageal junction adenocarcinoma. Patients must have metastatic or locally advanced-unresectable disease.
2. an Eastern Cooperative Oncology Group (ECOG) performance status of * 2.
3. At least one prior trastuzumab-containing regimen.
4. Metastatic breast cancer patients must have received a minimum of 1 and a maximum of 3 prior anti-HER2-based regimens, with documented progression on the most recent regimen which must contain trastuzumab or lapatinib
5. Gastric cancer patients must have received a minimum of 1 and a maximum of 2 prior anti-HER2-based regimens, with documented progression on the most recent regimen which must contain trastuzumab.
During the dose expansion part of the study:
6. Baseline tumor tissue must be obtained by biopsy
7. In dose expansion only, patients must have measurable disease as defined by RECIST v1.1 (at least one lesion * 10 mm in at least one dimension when assessed by CT or MRI, or a cutaneous lesion with clearly defined margins that measures * 10 mm in at least one dimension)

Exclusion Criteria
