Inclusion Criteria:  Capable to understand and sign the informed consent form (ICF) which includes compliance with the ICF and this protocol. In the Investigator's judgment, willing and able to complete all visits and assessments adhering to the prohibitions and restrictions specified in this protocol. Women or men aged ≥50 years when signing the ICF. Newly diagnosed, untreated, active subfoveal or juxtafoveal CNV lesions secondary to AMD in the study eye. (Active CNV was defined as leakage on FA and subretinal or intraretinal fluid on OCT with confirmation of the reading center during screening). The total lesion area (including hemorrhage, scar and neovascularization) of the study eye ≤12 disc area (DA) with confirmation of the reading center before randomization a. The BCVA letters between 24 and 73, inclusive, in the study eye, using Early Treatment Diabetic Retinopathy Study (ETDRS) charts. Clear ocular media and adequate pupillary dilatation to allow acquisition of good quality retinal images to confirm the diagnosis. Participants' fellow (non-study) eye must have had a BCVA of 24 letters or better.  Exclusion Criteria:  Macular-related retinal pigment epithelial tears in the study eye; scar, fibrosis or atrophy involving the fovea, or CNV due to other causes in the study eye (e.g., ocular histoplasmosis, trauma, or pathological myopia etc.) with confirmation of the reading center. The fellow (nonstudy) eye needs anti-VEGF IVT injection (e.g. CNV due to wAMD, trauma, pathological myopia, retina vein occlusion, diabetic macular edema, etc) in the next 3 months after randomization, in the investigator's judgment. Active or recent (within 1 month prior to dose 1) intraocular, extraocular or periocular infection (including conjunctivitis, keratitis, scleritis or endophthalmitis), or history of idiopathic or autoimmune-associated uveitis in either eye. Vitreous hemorrhage in the study eye within 3 months prior to dose 1. Aphakia (except intraocular lens) or posterior capsular rupture of the lens (except yttrium aluminium-garnet (YAG) laser posterior capsulotomy after intraocular lens implantation ≥1 month prior to first dose) in the study eye. Corneal dystrophy or history of corneal transplantation, scleral softening or history of scleral softening, history of rhegmatogenous retinal detachment or macular hole (Stage II, III or IV) in the study eye. Uncontrolled glaucoma (defined as intraocular pressure [IOP] ≥25 mmHg despite treatment with antiglaucoma medication), and/or glaucoma filtering surgery (e.g., trabeculectomy, scleral nipping, non-penetrating trabeculectomy, etc.), or advanced glaucoma resulting in a cup/disc ratio >0.8 in the study eye Equivalent spherical diopter of the study eye ≥-8D. For participants who had undergone refractive correction or cataract surgery, the equivalent spherical diopter of the study eye before surgery ≥-8D. Estimated by the Investigator, any concurrent intraocular condition except wAMD (e.g., diabetic retinopathy, dry AMD, retina vein occlusion, uveitis, angioid streaks, retinal detachment, epiretinal membrane, amblyopia, central serous chorioretinopathy, etc.) in the study eye that limited the potential to gain visual acuity upon treatment with the investigational product, or could have required medical or surgical intervention during the study to prevent or treat visual loss. Underwent intraocular surgery including verteporfin photodynamic therapy (PDT), transpupillary thermotherapy, macular translocation, vitrectomy, laser photocoagulation in macular area, other surgery in macular area or surgery to treat AMD. Previous extraocular or periocular surgery within 1 month or intraocular surgery (including cataract surgery, etc.) within 3 months prior to dose 1, or current unhealed wound, moderate or severe ulcer or history of fracture in the study eye. Subconjunctival or intraocular or systemic use of corticosteroids within 3 months (including subconjunctival or intraocular long-acting implant within 6 months) prior to dose 1 in the study eye. Previous systemic anti-VEGF therapy or IVT injection of any anti-VEGF drug into either eye or other ocular use of anti-VEGF drug within 3 months prior to dose 1. Participated in any drug (other than vitamins and minerals) or device clinical trials within 3 months or the duration of 5 half-lives of the study drug (which is longer) prior to dose 1 and have used the test drug or received device treatment. Pregnancy or lactation.  Infertile women fail to meet either of the following ones: 1) menopause (≥12 continuous months of amenorrhea with no identified cause other than menopause before screening); 2) surgically sterilized.  Men or fertile women fail to meet both of the following ones: 1) women of childbearing potential must have a negative urine or serum pregnancy test result within 14 days prior to initiation of the study intervention, and should not breastfeed; If the urine pregnancy test is positive, it must be confirmed by a serum pregnancy test; 2) agreement to remain abstinent (refrain from heterosexual intercourse) or use effective contraceptive methods from signed ICF to at least 6 months following the last dose of the study intervention. Effective contraceptive methods include bilateral tubal ligation, male sterilization, established, proper use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices (IUDs), and copper IUDs.  In the Investigator's judgment, there is evidence of a disease or condition that contraindicates the use an investigational drug or that might affect interpretation of the results of the study or render the participant at high risk for treatment complications (e.g. stroke or myocardial infarction within 6 months prior todose1, uncontrolled hypertension (systolic blood pressure≥160 mmHg, or diastolic blood pressure ≥100 mmHg), etc.). Uncontrolled diabetes (defined as HbA1c>10.0%). Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) is more than twice the upper limit of normal (ULN), and/or serum creatinine is 1.2 times more than the ULN, and is clinically significant in the opinion of the Investigator. Abnormal coagulation function（prothrombin time ≥ 3 seconds over ULN, activated partial thromboplastin time ≥ 10 seconds over ULN） Active disseminated intravascular coagulation and obvious bleeding tendency within 3 months prior to dose 1. Evidence of significant uncontrolled concomitant diseases such as cardiovascular diseases, nervous system diseases, respiratory system diseases, urinary system diseases, digestive system diseases and endocrine diseases. Current treatment for active systemic infection, or history of recurrent serious infections. Known active or suspected autoimmune diseases, requiring systemic immunosuppressive therapy. Positive for syphilis screening test or positive for human immunodeficiency virus (HIV) screening test. Known allergy to any component of the study intervention or history of allergy to fluorescein or indocyanine green, any anesthetics or antimicrobial agents used during the course of the study. In the Investigator's judgment, other conditions considered not amenable to this study. Participant who has been diagnosed to be COVID-19 or who has received COVID-19 vaccine within 1 month prior to dose 1.  Other protocol defined inclusion and exclusion criteria may apply.
