A Study to Evaluate the Efficacy and Safety of VIS-101 in Participants With Neovascular Age-Related Macular Degeneration

Inclusion criteria

• Willingness to sign the informed consent form, aged ≥50 years (on Day 0 of dosing), with no gender restrictions
• Able to adhere to the study protocol per the Investigator judgment
• Female participants of childbearing potential (WOCBP) or male participants with partners who are WOCBP must agree to use highly effective contraception from screening until 3 months after treatment completion
• Treatment-naïve CNV secondary to AMD (nAMD)
• Subfoveal CNV or juxtafoveal/extrafoveal CNV with a subfoveal component related to the CNV activity identified by FFA or OCT (where CNV activity is defined as showing evidence of subretinal fluid, subretinal hyperreflective material, or leakage) confirmed by the Central Reading Center
• Sufficiently clear ocular media and adequate pupillary dilatation to allow acquisition of good-quality retinal images to confirm diagnosis and follow up

Exclusion criteria

• Any major illness or major surgical procedure within 1 month before screening in the opinion of the investigator
• Active cancer within the past 12 months before screening except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, and prostate cancer with a Gleason score ≤6 and a stable prostate-specific antigen for >12 months
• Requirement for continuous use of any medications and treatments indicated as prohibited therapy
• Systemic treatment for suspected or active systemic infection on Day 0 Ongoing use of prophylactic antibiotic therapy may be acceptable if approved after discussion with the medical monitor
• Uncontrolled blood pressure, defined as systolic blood pressure >180 mmHg and/or diastolic blood pressure >100 mmHg whilst a participant is at rest on Day 0
• Stroke (cerebral vascular accident) or myocardial infarction within 6 months before Day 0
• History of other disease, metabolic dysfunction, physical examination finding, or historical or current clinical laboratory finding giving reasonable suspicion of a condition that contraindicates the use of the investigational drug or that might affect interpretation of the results of the study or renders the participant at high risk for treatment complications in the opinion of the investigator
• Pregnancy or breastfeeding, or intention to become pregnant during the study WOCBP must have a negative serum pregnancy test result within 28 days before initiation of study treatment.
• History of a severe allergic reaction or anaphylactic reaction to a biologic agent or known hypersensitivity to any component of VIS-101, aflibercept, study-related procedure preparations (including fluorescein and indocyanine green), dilating drops, or any of the anesthetic and anti-microbial drops used by the participant during the study
• Participation in an investigational trial that involves treatment with any drug or device (with the exception of vitamins and minerals) within 3 months before Day 0

11 Any prior or concomitant treatment for CNV or vitreomacular-interface abnormalities, including, but not restricted to, IVT treatment (e.g., anti-VEGF, steroids, tissue plasminogen activator, ocriplasmin, C3F8, air), periocular pharmacological intervention, argon laser photocoagulation, verteporfin photodynamic therapy, diode laser, transpupillary thermotherapy, or ocular surgical intervention

• Any history of macular pathology unrelated to AMD affecting vision or contributing to the presence of intraretinal or subretinal fluid

• Any concurrent intraocular condition (e.g., amblyopia, aphakia, retinal detachment, cataract, diabetic retinopathy or maculopathy, or epiretinal membrane with traction) that, in the opinion of the investigator, could either reduce the potential for visual improvement or require medical or surgical intervention during the study

• Any cataract surgery or treatment for complications of cataract surgery with steroids or YAG laser capsulotomy within 3 months before Day 0

• Any other intraocular surgery (e.g., pars plana vitrectomy, glaucoma surgery, corneal transplant, or radiotherapy)

• Previous periocular pharmacological or IVT treatment (including anti VEGF and/or anti VEGF/ANG2 medications) for other retinal diseases

• BCVA of hand motion or worse in the fellow eye

• Monocular (no fellow eye)

• Any history of idiopathic or autoimmune associated uveitis in either eye

• Active ocular inflammation or suspected or active ocular or periocular infection in either eye on Day 0

21 Aphakic lens status or anterior chamber intraocular lens or an absence of the posterior lens capsule. Previous violation of the posterior capsule is also an exclusion criterion unless it occurred due to prior laser capsulotomy in association with a prior in the bag lens implantation.
