3. Patients who have previously received disease progression or toxic side effects after first-line systemic chemotherapy are not tolerated;The standard first-line chemotherapy regimen was defined as a two-drug combination regimen of gemcitabine plus cisplatin, gemcitabine plus gio, or capecitabine plus oxaliplatin.Failure of first-line standard chemotherapy was defined as progression of disease during treatment or within 6 months after the last treatment;Or the toxic side effects of the treatment process are intolerable;

4. Presence of at least one measurable target lesion for further evaluation according to RECIST criteria;

5. Patients who had previously received A VEGF or VEGFR-targeted drug required progression 4 months after the last dose;

6. No systemic antitumor therapy in 4 weeks;

7. The patient has no evidence of biliary obstruction unless the obstruction is controlled by local treatment or the patient is decompressed by endoscopic or percutaneous stenting, and bilirubin is subsequently reduced to below the upper limit of 1.5x normal (ULN);

8. Eastern Cooperative Oncology Group (ECOG) performance status 0-1;Predicted survival ≥3 months;

9. Screening laboratory values must meet the following criteria (within past 14 days):

   • neutrophils ≥1.5×109/L ;
   • platelets ≥9g/dL；
   • hemoglobin ≥ 9.0 g/dL;
   • albumin≥3g/dL；
   • total bilirubin ≤ 1.5 x upper limit of normal (ULN); aspartic transaminase (AST) and alanine transaminase (ALT) ≤ 2.5 x ULN without, and ≤ 5 x ULN with hepatic metastasis; serum creatinine ≤1.5╳ULN;

10. Voluntary enrollment, good compliance, can cooperate with the experiment observation, and signed a written informed consent;

11. Males or female of childbearing potential must: agree to use using a reliable form of contraception (eg, oral contraceptives, intrauterine device, control sex desire, double barrier method of condom and spermicidal) during the treatment period and for at least 6 months after the last dose of study drug.

Exclusion Criteria

2. Prior antitumor therapy with chemotherapy, radical radiation therapy ，biological immunotherapy，targeted therapy within 4 weeks.
3. Prior participation in other clinical trials not approved or listed in China within past 4 weeks；
4. Prior major surgery within past 4 weeks (diagnostic surgery excluded);
5. International standardized ratio (INR) >1.5 or partially activated prothrombin time (APTT) >1.5×ULN;
6. Clinically significant severe electrolyte abnormality judged by investigator ;
7. Hypertension that is not controlled by the drug, and is defined as: SBP≥140 mmHg and/or DBP≥90 mmHg;
8. Currently suffering from poorly controlled diabetes (after regular treatment, fasting plasma glucose concentration ≥10mmol/L);
9. The patient currently has disease or condition that affects the absorption of the drug, or the patient cannot be administered orally;
10. Digestive tract disease such as gastric and duodenal active ulcer, ulcerative colitis or unresected tumor, or other conditions determined by the investigator that may cause gastrointestinal bleeding and perforation;
11. Evidence of bleeding tendency or history within 3 months, or thromboembolic event (including a stroke event and/or a transient ischemic attack) occurred within 12 month;
