Brief Summary:
The purpose of this study is to compare the efficacy and safety of ESBA1008 versus EYLEA® in the treatment of exudative age-related macular degeneration.

Condition or disease Intervention/treatment Phase
Exudative Age-Related Macular Degeneration Drug: ESBA1008 solution Drug: Aflibercept Phase 2

Detailed Description:
This study consisted of 16 visits (Screening, Baseline [Day 0], and 14 post-baseline assessment visits) that occurred at 4-week intervals through Week 56. Enrolled subjects were randomized 1:1 to receive ESBA1008 or EYLEA. All subjects received active intravitreal (IVT) injections at baseline with 2 additional loading doses of the assigned investigational product at 4-week intervals (ie, at Weeks 4 and 8) and then received further injections at 8-weeks intervals at Weeks 16, 24, and 32. Subjects in the ESBA1008 group also received an injection at Week 44, while subjects in the EYLEA group also received injections at Weeks 40 and 48. To maintain the study masking, subjects in the ESBA1008 group received sham injections at Weeks 40 and 48 (when the subjects in the EYLEA group received active injections), while subjects in the EYLEA group received a sham injection at Week 44 (when the subjects in the ESBA1008 group received an active injection). All subjects were followed up to Week 56. Week 40 visit was the end of assessment period for the 8-week treatment cycle.

Primary Outcome Measures :
  1. Best-Corrected Visual Acuity (BCVA) Change From Baseline (No. of Letters) to Week 12 [ Time Frame: Baseline (Day 0), Week 12 ]
    This outcome measure was used to compare the ESBA1008 and EYLEA groups in regards to fluctuations in treatment effect during the maintenance phase with 8-week treatment cycles (ie, to evaluate treatment effect stability during the maintenance phase). BCVA (with spectacles or other visual corrective devices) using Early Treatment Diabetic Retinopathy Study (ETDRS) testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. One eye (study eye) contributed to the analysis.


Secondary Outcome Measures :
  1. BCVA Change From Baseline (No. of Letters) to Week 16 [ Time Frame: Baseline (Day 0), Week 16 ]
    BCVA (with spectacles or other visual corrective devices) using ETDRS testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. One eye (study eye) contributed to the analysis.

  2. BCVA Change From Baseline (No. of Letters) by Visit [ Time Frame: Baseline (Day 0), Week 4, Week 8, Week 20, Week 24, Week 28, Week 32, Week 36, Week 40, Week 44, Week 48, Week 52, Week 56 ]
    BCVA (with spectacles or other visual corrective devices) using ETDRS testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. One eye (study eye) contributed to the analysis.

  3. Average BCVA Change From Baseline (No. of Letters) Over the Periods of Week 4 to Week 16, Week 4 to Week 24, Week 4 to Week 40, and Week 4 to Week 56 [ Time Frame: Baseline (Day 0), Week 4, Week 8, Week 12, Week 16, Week 20, Week 24, Week 28, Week 32, Week 36, Week 40, Week 44, Week 48, Week 52, Week 56 ]
    The purpose of this outcome measure was to assess the integrated effect of the treatment for different study periods and to provide more robust estimate of the absolute treatment effects. BCVA (with spectacles or other visual corrective devices) using ETDRS testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. These changes were computed as the average of the changes from baseline to each monthly study visit corresponding to each period. One eye (study eye) contributed to the analysis.

  4. Average BCVA Change From Week 12 (No. of Letters) Over the Periods of Week 16 to Week 24, Week 16 Week 40, and Week 16 to Week 56 [ Time Frame: Week 12, Week 16, Week 20, Week 24, Week 28, Week 32, Week 36, Week 40, Week 44, Week 48, Week 52, Week 56 ]
    The purpose of this outcome measure was to assess the average maintenance level of BCVA following the 3 loading treatments (ie, after Week 12). BCVA (with spectacles or other visual corrective devices) using ETDRS testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. These changes were computed as the average of the changes from Week 12 to each monthly study visit corresponding to each period. One eye (study eye) contributed to the analysis.

  5. One-Month BCVA Changes (No. of Letters) Following No Treatment for 1-Month [ Time Frame: Week 12, Week 16, Week 20, Week 24, Week 28, Week 32, Week 36, Week 40, Week 44, Week 48, Week 52, Week 56 ]
    The purpose of this outcome measure was to assess the stability of BCVA during the second month of 8-week/12-week treatment cycles and specifically to identify potential under treatment. BCVA (with spectacles or other visual corrective devices) using ETDRS testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. One eye (study eye) contributed to the analysis.

  6. One-Month BCVA Changes (No. of Letters) Following Treatment by Visit [ Time Frame: Week 16, Week 20, Week 24, Week 28, Week 32, Week 36, Week 40, Week 44, Week 48, Week 52 ]
    The purpose of this outcome measure was to assess the potential treatment needs present at these treatment visits. BCVA (with spectacles or other visual corrective devices) using ETDRS testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. One eye (study eye) contributed to the analysis.

  7. Two-Months BCVA Changes (No. of Letters) Following No Treatment for 1 Month in ESBA Treatment Group [ Time Frame: Week 36, Week 44, Week 48, Week 56 ]
    BCVA (with spectacles or other visual corrective devices) using ETDRS testing was reported in letters read correctly. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. This outcome measure was pre-specified for ESBA1008 arm only. One eye (study eye) contributed to the analysis.

  8. Central Subfield Thickness (CSFT) Change From Baseline by Visit [ Time Frame: Baseline (Day 0), Week 4, Week 8, Week 12, Week 16, Week 20, Week 24, Week 28, Week 32, Week 36, Week 40, Week 44, Week 48, Week 52, Week 56 ]
    CSFT (average thickness in the central subfield centered at the fovea) as measured using Spectral-Domain Optical Coherence Tomography (SD-OCT). Reduction in CSFT measurement from baseline indicates improvement. One eye (study eye) contributed to the analysis.
