Brief Summary:
In this study researchers want to learn more about changes in visual acuity (clarity of vision) with a high dose treatment with Aflibercept (Eylea) in patients suffering from neovascular age-related macular degeneration (nAMD). Neovascular AMD is an eye disease that causes blurred vision or a blind spot due to abnormal blood vessels that leak fluid or blood into the light sensitive lining inside the eye (retina). The fluid buildup causes the central part of the retina (macula) responsible for sharp, straight-ahead vision to swell and thicken (edema), which distorts vision.

Neovascular Age-Related Macular Degeneration Drug: Aflibercept High Dose VEGF Trap-Eye (BAY86-5321) Drug: Aflibercept VEGF Trap-Eye (Eylea, BAY86-5321) Phase 3

Secondary Outcome Measures :
  1. Change in BCVA measured by the ETDRS letter score [ Time Frame: At baseline and week 60 ]
  2. Proportion of participants with no intraretinal fluid (IRF) and no subretinal fluid (SRF) in central subfield [ Time Frame: At week 16 ]
  3. Proportion of participants gaining at least 15 letters in BCVA [ Time Frame: At baseline and week 48 ]
  4. Proportion of participants achieving an ETDRS letter score of at least 69 [ Time Frame: At week 48 ]
  5. Change in choroidal neovascularization (CNV) size [ Time Frame: At baseline and week 48 ]
  6. Change in total lesion area [ Time Frame: At baseline and week 48 ]
  7. Proportion of participants with no IRF and no SRF in the center subfield [ Time Frame: At week 48 ]
  8. Change in central subfield retinal thickness (CST) [ Time Frame: At baseline and week 48 ]
  9. Change in National Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25) total score [ Time Frame: At baseline and week 48 ]
  10. Treatment-emergent adverse events (AEs) and serious AEs (SAEs) [ Time Frame: Up to 96 weeks ]
  11. Systemic exposure to aflibercept as assessed by plasma concentration [ Time Frame: Up to week 48 ]
  12. Assessment of immunogenicity to aflibercept by measuring the incidence of treatment-emergent anti-drug antibodies (ADA) response [ Time Frame: Up to week 96 ]

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Active subfoveal CNV secondary to nAMD, including juxtafoveal lesions that affect the fovea as assessed in the study eye.
  • Total area of CNV (including both classic and occult components) must comprise greater than 50% of the total lesion area in the study eye.
  • BCVA ETDRS letter score of 78 to 24 (corresponding to a Snellen equivalent of approximately 20/32 to 20/320) in the study eye.
  • Decrease in BCVA determined to be primarily the result of nAMD in the study eye.
  • Presence of IRF and/or SRF affecting the central subfield of the study eye on OCT.

  • Myopia of a spherical equivalent of at least 8 diopters in the study eye prior to any refractive or cataract surgery.
  • History or clinical evidence of diabetic retinopathy, diabetic macular edema, or any retinal vascular disease other than nAMD in either eye.
  • Evidence of extraocular or periocular infection or inflammation (including infectious blepharitis, keratitis, scleritis, or conjunctivitis) in either eye at the time of screening/randomization.
  • Uncontrolled blood pressure (defined as systolic >160 mmHg or diastolic >95 mmHg).
