What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dose-limiting toxicities (DLTs) of Apatinib mesylate in patients with unresectable locally advanced or metastatic gastric cancer | Graded and described using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v 4.03 | First 28 days of dosing | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of Adverse events (AEs), Serious AEs (SAEs), clinical laboratory abnormalities, and ECG abnormalities | Incidence and severity of treatment-related adverse events reported and their relationship to Apatinib mesylate will be assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.3) | From date of registration to time of first progressive disease(PD) or death, an average of 1 year | 
| Duration of Response(Stable disease, partial response or Complete response) | Tumor response and progression will be evaluated using RECIST v 1.1. | From date of registration to time of first progressive disease(PD) or death, an average of 1 year |
