A Study to Compare LY09004 and Eylea in the Treatment of Wet Age-related Macular Degeneration（wAMD）

A randomized, double-blind, parallel controlled, multicenter clinical trial to compare the efficacy and safety of LY09004 and EYLEA in the Treatment of Wet Age-related Macular Degeneration（wAMD)

This is a randomized, double-blind, parallel controlled, multicenter clinical trial.

The primary objective is to assess the efficacy similarity of LY09004 and EYLEA in the treatment of w-AMD.

The secondary objective is to assess the safety similarity of LY09004 and EYLEA in the treatment of w-AMD.

13. Any history of glaucoma;
14. Any evidence of pseudocapsular exfoliation syndrome in either eye;
15. A history of vitreous hemorrhage within 3 months before screening in either eye;
16. Any systemic drug (currently in use or may need to use) could cause lens toxicity or retinal toxicity, such as desferrioxamine, chloroquine/hydroxychloroquine, tamoxifen, phenothiazine, ethambutol, etc.;
17. History of allergy to the therapeutic or diagnostic drugs used in the research protocol, including allergies to the test articles;
18. Diabetic subjects with diabetic retinopathy or glycosylated hemoglobin\> 9%;
19. Any history of surgery within 1 month before screening, and/or any currently unhealed wounds, ulcers, fractures, etc.;
20. Any infectious disease requiring systemic treatment (oral, intramuscular or intravenous) during screening;

22. History of diffuse intravascular coagulation and obvious bleeding tendency (such as hemoptysis, hematemesis, severe purpura, etc.) within 3 months before screening, or use of anticoagulant and antiplatelet therapy other than aspirin/NSAIDs within 14 days before screening;
23. Subjects with systemic immune diseases;
24. Poorly-controlled blood pressure (defined as: after receiving antihypertensive drugs, the subject's systolic value ≥160 mmHg or diastolic value ≥100 mmHg at seat);
25. Any uncontrollable clinical disease (such as serious mental, respiratory and other system diseases and malignant tumors);
26. Abnormal liver and kidney function (ALT, AST≥2.5 times the upper limit of normal; total bilirubin≥1.5 times the upper limit of normal; Crea, urea/urea nitrogen≥1.2 times the upper limit of normal);
