To Evaluate The Role of Intravitreal Aflibercept Injection (2.0 mg) in the Management of Previously Treated Patients With Exudative AMD

Study Overview
=================
Brief Summary
-----------------
This is an open label study to evaluate intravitreally administered 2.0 mg intravitreal aflibercept injection in patients who have been previously treated for AMD and have persistent or recurrent fluid despite monthly intravitreal anti-VEGF therapy.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Intravitreal aflibercept<br>All eligible patients will receive intravitreal aflibercept injection (2.0mg) every 4 weeks (monthly) for the first 12 weeks (3 months), followed by 2 mg once every 8 weeks (2 months) through Week 24.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of Patients With no Fluid on OCT at Week 24 | No primary outcome data can be found or provided. | 24 week | 
| Mean Change in Visual Acuity From Baseline to Week 16 | Visual acuity was documented via BCVA at every study visit. | Baseline to Week 16 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Change in OCT Central Retinal Lesion Thickness From Baseline to Week 16 | OCT is performed on the Spectralis spectral domain OCT machine (Heidelberg Engineering, Germany). The OCT is centered on the fovea. The OCT examination will use the 19 scan mode on the Spectralis averaging at least 25 images per scan. Follow-up visits will use the follow-up protocol on the Spectralis , automatically placing follow-up scans in precisely the same location as the baseline scan. | Baseline and week 16 | 
| Mean Change in OCT Greatest Height of Pigment Epithelial Detachment From Baseline to Week 16 | OCT is performed on the Spectralis spectral domain OCT machine (Heidelberg Engineering, Germany). The OCT is centered on the fovea. The OCT examination will use the 19 scan mode on the Spectralis averaging at least 25 images per scan. Follow-up visits will use the follow-up protocol on the Spectralis , automatically placing follow-up scans in precisely the same location as the baseline scan. | Baseline and 16 weeks |
