The study is a 64-week randomized, double-masked, multi-center, active-controlled, two-arm study in patients with nAMD (neovascular age related macular degeneration) who have not previously received anti-VEGF (vascular endothelial growth factor) treatment. Patients who consent will undergo screening assessments to evaluate their eligibility based on the inclusion and exclusion criteria.

Inclusion Criteria

Signed informed consent must be obtained prior to participation in the study
Male or female patients 50 years of age at screening who are treatment naive
Active choroidal neovascularization (CNV) secondary to AMD that affects the central subfield, including retinal angiomatous proliferation (RAP) with a CNV component, confirmed by presence of active leakage from CNV seen by fluorescein angiography and sequellae of CNV, e.g. pigment epithelial detachment (PED), subretinal or sub-retinal pigment epithelium (sub-RPE) hemorrhage, blocked fluorescence, macular edema (study eye)
Presence of intraretinal fluid (IRF) or subretinal fluid (SRF) that affects the central subfield, as seen by Spectral Domain Optical Coherence Tomography (SD-OCT) (study eye)
Best-corrected visual acuity (BCVA) score between 83 and 38 letters, inclusive, using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at both screening and baseline visit (study eye)

Exclusion Criteria

Ocular conditions/disorders at screening or baseline which could, in the opinion of the investigator, prevent response to study treatment or may confound interpretation of study results, compromise visual acuity or require planned medical or surgical intervention during the first 12-month study period, structural damage of the fovea, atrophy or fibrosis at the center of the fovea (study eye)
Any active intraocular or periocular infection or active intraocular inflammation, at screening or baseline (study eye)
Uncontrolled glaucoma defined as intraocular pressure (IOP) > 25 mmHg on medication, or according to investigator's judgment, at screening or baseline (study eye)
Ocular treatments: previous treatment with any anti-vascular endothelial growth factor (VEGF) drugs or investigational drugs, intraocular or periocular steroids, macular laser photocoagulation, photodynamic therapy, vitreoretinal surgery, intraocular surgery (study eye)
Stroke or myocardial infarction during the 6-month period prior to baseline
Systemic anti-VEGF therapy at any time
Other protocol-defined inclusion/exclusion criteria may apply
