Group Intervention Description Aflibercept (IAI) 2 mg Intravitreal Aflibercept Injection (IAI) Participants were administered intravitreal injection of Aflibercept (IAI) 2 mg Q4 on Day 1, Week 4 and Week 8 for 3 initial doses up to Week 12. At Week 12, participants were re-randomized to receive IAI Q8 or Q12 (beginning at Week 16 or 20) or REGN910-3 (6 mg:2 mg) Q8 beginning at Week 16 through Week 32. REGN910-3 (3 mg: 2 mg) REGN910-3 Participants were administered intravitreal injection of REGN910-3 (3 milligram \[mg\]:2 mg) every 4 weeks (Q4) on Day 1, Week 4, and Week 8 for 3 initial doses followed by every Week 8 (Q8) dosing beginning at Week 16 up to Week 32. REGN910-3 (6 mg:2 mg) REGN910-3 Participants were administered intravitreal injection of REGN910-3 (6 mg:2 mg) Q4 on Day 1, Week 4 and Week 8 for 3 initial doses. At Week 12, participants were re-randomized to receive REGN910-3 (6 mg:2 mg) Q8 or Q12 (beginning at Week 16 or Week 20) through Week 32. Aflibercept (IAI) 2 mg REGN910-3 Participants were administered intravitreal injection of Aflibercept (IAI) 2 mg Q4 on Day 1, Week 4 and Week 8 for 3 initial doses up to Week 12. At Week 12, participants were re-randomized to receive IAI Q8 or Q12 (beginning at Week 16 or 20) or REGN910-3 (6 mg:2 mg) Q8 beginning at Week 16 through Week 32.
- Primary Outcome Measures
Name Time Method Change From Baseline in Best Corrected Visual Acuity (BCVA) Measured by Early Treatment Diabetic Retinopathy Study (ETDRS) Letter Score at Week 12 At Week 12 Visual function of the study eye was assessed using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol at 4 meters. Best Corrected Visual Acuity (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.
Change From Baseline in Best Corrected Visual Acuity (BCVA) Measured by Early Treatment Diabetic Retinopathy Study (ETDRS) Letter Score at Week 36 At Week 36 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 36.
- Secondary Outcome Measures
Name Time Method Change From Baseline in Central Sub-field Retinal Thickness (CST) Measured by Spectral Domain Optical Coherence Tomography (SD-OCT) at Week 36 At Week 36 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 36.
Change From Baseline in Central Sub-field Retinal Thickness (CST) Measured by Spectral Domain Optical Coherence Tomography (SD-OCT) at Week 12 At Week 12 Central Sub-field Retinal Thickness (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 last observation carried forward (LOCF) post-baseline value at Week 12.
Change From Baseline in Choroidal Neovascularization (CNV) Area at Week 36 At Week 36 Choroidal neovascularization (CNV) was evaluated using fluorescein angiography (FA).CNV area values measured in square millimeters (mm\^2); lower values represent better outcomes.
Change From Baseline in Total Lesion Area at Week 12 At Week 12 Total lesion area was evaluated using fluorescein angiography (FA). Lesion area values measured in square millimeters (mm\^2); lower values represent better outcomes.
Change From Baseline in Total Lesion Area at Week 36 At Week 36 Total lesion area was evaluated using fluorescein angiography (FA). Lesion area values measured in square millimeters (mm\^2); lower values represent better outcomes.
Change From Baseline in Choroidal Neovascularization (CNV) Area at Week 12 At Week 12 Choroidal neovascularization (CNV) was evaluated using fluorescein angiography (FA).CNV area values measured in square millimeters (mm\^2); lower values represent better outcomes.
