Brief Summary

This study is a randomized, prospective, exploratory, descriptive, open label, parallel group, post-authorization study designed to describe and evaluate two aflibercept treatment regimens aimed at achieving and maintaining a maximum visual function benefit (i.e., BCVA stability). The goal of the study is to compare two strategies for dosing regimen with aflibercept in wet AMD: the standard regimen (one injection every 8 weeks after 3 monthly loading doses in the treatment of wet age-related macular degeneration) versus the treat and extend protocol (details outlined below in the "Study Design" section) aiming at achieving and maintaining maximum visual acuity benefit while minimizing the number of injections. Patients will be randomized at week 8 (Month 2) in a proportion of 1:2 (Standard treatment : treat and extend treatment). We aim to demonstrate that the Treat and Extend regimen is equivalent or better to the standard fixed interval regimen in terms of change in patients' visual acuity after a year of treatment and that patients in the Treat and Extend arm will receive fewer injections and fewer visits, than their counterparts in the standard regimen arm. The results could be used to generate a base for future controlled-randomized clinical trials on the timing of treatment administration for patients with wAMD.

Eligibility Criteria

• Age: 50 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patient who are able to give written informed consent
• Patients 50 years of age or older
• Patients with a diagnosis of treatmenttreatment-naive CNV secondary to AMD in the study eye, for which aflibercept treatment hashas been prescribed by the treating physician. This includes patients with lesion(s) with less than 50% hemorrhage, less that 50% fibrosis, and/or serious pigment epithelial detachment (PED)
• Patients with best corrected visual acuity score in the study eye between 78 and 19 letters inclusively, using ETDRS visual acuity testing charts at a testing distance of 4 meters (approximate Snellen equivalent of 20/32 to 20/400 at screening)
• Females of childbearing potential must, in the opinion of the Investigator, be using a medically effective method of contraception to prevent pregnancy and agree to use an acceptable method of contraception for the duration of their participation in this study. Effective contraception should be used by subjects during the study and for three months after treatment. Effective methods of contraception include, but are not limited to, (i) condoms (male or female) with or without a spermicidal agent; (ii) diaphragm or cervical cap with spermicide; (iii) intra-uterine device; (iv) hormone-based contraception.

You may not qualify if:

• Patients with a structural foveal damage - advanced sub retinal fibrosis or significant geographic atrophy involving the foveal center (lack of morphological reserve) in the study eye
• Patients with confounding severe ocular disease in the study eye (such as uncontrolled glaucoma, diabetic retinopathy likely to be visually significant within 2 years, cataract presumably requiring surgery within 2 years) -vitreous or pre-retinal haemorrhage obscuring the central macula, or presence of rhegmatogenous retinal detachment
• Patients with clinical suspicion of polypoidal choroidal vasculopathy
• Patients with active or suspected ocular per ocular infections in either eye
• Patients with active intraocular inflammation in either eye
• Patients with a known sensitivity to Aflibercept or any component of its formulation
• Patients physically unable to tolerate intravenous fluorescein angiography
• Pregnant or breastfeeding female patients
• Any patient with recent history of new onset cardiac disease or thromboembolic event (within 12 months of Baseline visit)
• Patients having received systemic treatment with any other anti-VEGF therapy 60 days prior to enrollment
• Patients having had any prior treatment in the study eye (Avastin, Lucentis, Visudyne, Ozurdex, external radiation therapy, transpupillary thermotherapy, or any intravitreal injection)
• Concurrent participation in a clinical trial or within 30 days prior to enrollment
• Patients with any other condition which, in the opinion of the principal investigator, would require treatment that would significantly impact the treatment assessments during the study.
