Brief Summary:

The primary objective of the study was to explore the effect of REGN2176-3 on the Early Treatment Diabetic Retinopathy Scale (ETDRS) best-corrected visual acuity (BCVA) in participants with neovascular age-related macular degeneration (AMD), compared to intravitreal aflibercept injection (IAI) monotherapy.

The secondary objectives of the study were the following:

  • To explore the effect of 2 dose levels of IVT REGN2176-3 on anatomical changes of CNV in participants with nAMD compared to IAI monotherapy (at week 12)
  • To evaluate if short-term treatment with REGN2176-3 followed by IAI monotherapy offered the same or additional benefit compared to continuous treatment with REGN2176-3. Also to determine if there was benefit in initiating IAI treatment prior to REGN2176-3 compared to continuous treatment with IAI.
  • To assess the safety and tolerability of IVT REGN2176-3 in participants with nAMD

Primary Outcome Measures :
  1. Change From Baseline in Best Corrected Visual Acuity (BCVA) of the Study Eye at Week 12 [ Time Frame: Baseline, Week 12 ]
    Visual function of the study eye was assessed using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol at 4 meters. BCVA score was measured using an eye chart and was reported as the number of letters read correctly at a testing distance of 4 meters using the ETDRS Scale (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved. Change from baseline calculated by subtracting baseline value from observed post-baseline value at Week 12.


Secondary Outcome Measures :
  1. Change From Baseline in Central Subfield Retinal Thickness (CST) at Week 12, as Measured by Optical Coherence Tomography (OCT) [ Time Frame: Baseline, Week 12 ]
    CST was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation. A negative change from baseline indicated improvement. Change from baseline calculated by subtracting baseline value from LOCF post-baseline value at Week 12.

  2. Percentage of Participants With Complete Resolution of Intraretinal and Subretinal Fluid From Baseline at Week 12 Measured by Optical Coherence Tomography (OCT) [ Time Frame: Week 12 ]
    CST was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation.

  3. Change From Baseline in Choroidal Neovascularization (CNV) Area at Week 12 Measured by Fluorescein Angiography (FA) [ Time Frame: Baseline, Week 12 ]
    The anatomical state of the retinal vasculature of the study eye and the fellow eye was evaluated by funduscopic examination, fundus photography and FA to evaluate the total lesion area, CNV area, classic CNV area, and fluorescein leakage. CNV area values measured in square millimeters, each disc area was equivalent to 2.54 mm^2 on the retina; lower values represent better outcomes.

  4. Change From Baseline in Total Lesion Size at Week 12 Measured by Fluorescein Angiography (FA) [ Time Frame: Baseline, Week 12 ]
    Total Lesion Size was assessed by Fluorescein Angiography.

  5. Percentage of Participants Who Gained At Least 15 Letters in BCVA From Baseline at Week 12, Measured by 4-meter Early Treatment Diabetic Retinopathy Scale (ETDRS) [ Time Frame: Week 12 ]
    Visual function of the study eye was assessed using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol at 4 meters. BCVA score was measured using an eye chart and was reported as the number of letters read correctly at a testing distance of 4 meters using the ETDRS Scale (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved. This outcome assessed the percentage of participants who gained 15 or more letters of visual acuity at Week 12 compared with baseline.

  6. Percent Change From Baseline in Subretinal Hyperreflectivity Material (SHM) at Week 12 Measured by Optical Coherence Tomography (OCT) [ Time Frame: Baseline, Week 12 ]
    SHM was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation. A negative change from baseline indicated improvement.

  7. Change From Baseline in Central Retinal/Lesion Thickness at Week 12 Measured by Optical Coherence Tomography (OCT) [ Time Frame: Baseline, Week 12 ]
    CST was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation. A negative change from baseline indicated improvement. Change from baseline calculated by subtracting baseline value from LOCF post-baseline value at Week 12.
