Eligibility Criteria
Inclusion Criteria
- •Active subfoveal CNV lesion or juxtafoveal CNV lesion with foveal involvement that is secondary to AMD in the Study Eye.
- •An ETDRS BCVA score between 60 and 25 (inclusive) letters in the Study Eye.
Exclusion Criteria
- •Any previous treatment for neovascular AMD.
- •Clinically significant ocular disorders (other than neovascular AMD), which may interfere with assessment of BCVA, assessment of safety, or fundus imaging.
- •Any current (or history of a) social, psychological, or medical condition that precludes enrolment into the study.
- •Additional inclusion/exclusion criteria apply.

Outcomes
Primary Outcomes
Mean Change in Early Treatment Retinopathy Study (ETDRS) Best-corrected Visual Acuity (BCVA) Letters
Time Frame: Baseline to Week 52
To determine the efficacy of intravitreal 2.0 mg OPT-302 when administered in combination with intravitreal 2.0 mg aflibercept, in participants with neovascular age-related macular degeneration (nAMD), in terms of change in ETDRS BCVA letter score in the study eye from Baseline to Week 52. The primary analysis presented used mixed model for repeated measures in the overall population. (A positive outcome measure means an improvement in ETDRS BCVA letter score from baseline; a negative outcome measure means a deterioration in ETDRS BCVA letter score from baseline)
Secondary Outcomes
- Proportion of Participants Gaining 15 or More ETDRS BCVA Letters(Baseline to Week 52)
- Proportion of Participants Gaining 10 or More ETDRS BCVA Letters(Baseline to Week 52)
- Proportion of Participants With Absence of Both Sub-retinal Fluid and Intra-retinal Cysts by SD-OCT(at Week 52)
- Change in Choroidal Neovascularisation (CNV) Area by Fluorescein Angiography (FA)(Baseline to Week 52)
