The primary objective of the study was to assess investigate the pharmacokinetic effects of Apatinib on Rosuvastatin or Metformin.

The secondary objective of the study was to assess the safety of Apatinib alone or Rosuvastatin/Metformin alone or concomitant medication.

Exclusion Criteria:

Subjects meeting any one of the followings will be excluded in this study:

1. Patients with gastrointestinal diseases that affect the use or absorption of drugs, such as gastric cancer or intestinal cancer, unable to swallow, chronic diarrhea, intestinal obstruction, large stomach or total gastrectomy, or within 6 months before the first medication Patients with abdominal fistula, gastrointestinal perforation or abdominal abscess;
2. Active (without medical control) brain metastases, cancerous meningitis, spinal cord compression patients, or imaging CT or MRI examination at screening to find diseases of the brain or pia mater
3. Presence of clinically symptomatic third space fluid (e.g. large pleural fluid or ascites) that cannot be controlled by drainage or other methods;
4. Patients with hypertension, or patients with a history of hypertension
5. Patients with NYHA Class III-IV cardiac insufficiency or left ventricular ejection fraction (LVEF) < 50% by echocardiography; uncontrolled arrhythmias (QTc interval ≥ 450 ms in males and ≥ 470 ms in females);
6. During the study period, patients should be used drugs that may lead to prolonged QTc interval (such as antiarrhythmic drugs, quinidine, disopyramide, procainamide, sotalol, amiodarone, etc.)
7. Patients with abnormal coagulation function (INR > 1.5 or prothrombin time (PT) > ULN + 4 s or APTT > 1.5 ULN)
8. Patients with clinically significant bleeding or clear bleeding tendency within 3 months prior to the first dose, such as coughing up blood, hemoptysis, GI bleeding, hemorrhagic gastric ulcer, or baseline fecal occult blood (FOB) ++ and above. Gastroscopy is required for patients with FOB (+) and no surgical resection of primary gastric tumor. In case of ulcerative gastric cancer, patients are not enrolled due to a risk of acute gastrointestinal hemorrhage;
9. Events of arterial/venous thrombosis within 6 months prior to the first dose, such as cerebrovascular accidents (including transient ischemic attacks, cerebral hemorrhage, brain infarction), deep vein thrombosis, and pulmonary embolism;
10. Known hereditary or acquired hemorrhage and thrombophilia (such as hemophilia, coagulopathy, thrombocytopenia, hypersplenism, etc.);

12. Have undergone major surgery or with severe traumatic injury, fracture, or ulcer within 4 weeks prior to the first dose; There is no previous wound healing.
13. Use of study drugs in other clinical trials within 4 weeks prior to the first dose;
14. Drugs that is CYP3A inhibitor, or the transporter BCRP or MATE1 inhibitor, or drugs that affect gastric acid secretion, or Chinese herbal medicines within 2 weeks before the first dose; use the drug that is metabolic enzyme CYP3A inducer within 4 weeks before the first dose
15. Infectious disease screening (hepatitis B virus surface antigen, hepatitis C virus antibody, Treponema pallidum antibody and human immunodeficiency virus antibody) positive
16. History of immunodeficiency, with acquired, congenital immunodeficiency disease, or history of organ transplantation
