Brief Summary
This study is designed to evaluate the safety and efficacy of every 2 week intravitreal aflibercept injections in a population of neovascular AMD patients that have demonstrated refractory subretinal fluid with or without intraretinal fluid despite prior monthly intravitreal aflibercept treatment.

Continued Q2 Week Treatment
EXPERIMENTALWill receive intravitreal aflibercept (2.0mg) injections for an additional four consecutive 2 week intervals at weeks 18, 20, 22, and 24
Treat-And-Extend Treatment

Interventions
Aflibercept is a recombinant fusion protein consisting of portions of human VEGF receptors 1 and 2 extracellular domains fused to the Fc portion of human IgG1 formulated as an iso-osmotic solution for intravitreal administration.
Eligibility Criteria
You may qualify if:
- Age ≥ 50 years
- A diagnosis of choroidal neovascularization related to age-related macular degeneration
- ETDRS refracted BCVA ≥ 20/200
- Prior treatment with any anti-VEGF agent for ≥ 12 months
- Prior treatment with at least five intravitreal aflibercept at the time of screening (week -2) with an average inter-treatment interval \<35 days
- Presence of persistent subretinal fluid with or without intraretinal fluid on OCT at most recent standard of care visit occurring 28-35 days following most recent intravitreal aflibercept injection
- Demonstration of definite improvement in overall retinal thickness and/or subretinal fluid on OCT based on evaluation of examining investigator at screening visit (week -2) 13-15 days following most recent standard of care visit
- o Note: screening OCT will be performed prior to dilation to allow for undilated ETDRS BCVA testing following confirmation of eligibility
- Willing and able to comply with clinic visits and study-related procedures
- Provide signed informed consent
You may not qualify if:
- Prior treatment with verteporfin, external-beam radiation therapy, or transpupillary thermotherapy in the study eye
- Previous subfoveal focal laser photocoagulation involving the foveal center in the study eye
- Concurrent eye disease in the study eye that could compromise visual acuity (e.g. advanced diabetic retinopathy, advanced glaucoma)
- Active intraocular inflammation (grade trace or above) in the study eye
- Current vitreous hemorrhage in the study eye
- History of macula-involving rhegmatogenous retinal detachment or macular hole (Stage 2 - 4) in the study eye
- Active infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye
- Aphakia in the study eye
- Uncontrolled glaucoma in the study eye (defined as intraocular pressure ≥30 mmHg despite treatment with anti-glaucoma medication)
- Use of systemic anti-VEGF medications within 6 months of screening visit
- History of cerebrovascular accident, myocardial infarction, ventricular arrhythmia, unstable angina, coronary or peripheral artery bypass or stenting within 6 months of day 0
- History of deep vein thrombosis or pulmonary embolus within 6 months of day 0
- Uncontrolled hypertension (\>160/100 on medical treatment)
- Pregnant or breast-feeding women
- Sexually active men\* or women of childbearing potential\*\* who are unwilling to practice adequate contraception prior to the initial dose administration (baseline visit, week 0). Adequate contraceptive measures include stable use of oral contraceptives or other prescription pharmaceutical contraceptives for 2 or more menstrual cycles prior to screening; intrauterine device; bilateral tubal ligation; vasectomy; condom plus contraceptive sponge, foam, or jelly, or diaphragm plus contraceptive sponge, foam, or jelly.
