| Neovascular Age-Related Macular Degeneration | Drug: Drug: GB-102 Drug: Aflibercept | Phase 2 |
Phase 2b, multicenter, visual examiner-masked, randomized active-controlled, parallel-arm design study to evaluate the safety and duration of the effect of GB-102, as measured by time to first rescue treatment across multiple dose levels of GB-102 administered every 6 months as compared to intravitreal (IVT) aflibercept administered every 2 months in subjects with neovascular (wet) age-related macular degeneration who have received prior induction with anti-vascular endothelial growth factor (VEGF)
Extension Study:
To monitor the safety and duration of effect of IVT GB-102 administered every 6 months compared to IVT aflibercept administered every 2 months in subjects in ALTISSIMO (Core Study) who complete all study visits through Month 12 (Day 360) and who do not require/receive rescue treatment at the Month 12 (Day 360) final study visit

- Time to First Rescue Treatment [ Time Frame: Baseline through 12 months ]Kaplan-Meier estimate of the median time to first rescue treatment.
- Time to Fulfillment of at Least One Rescue Criterion [ Time Frame: 6 months through 12 months ]Assessment of time to fulfillment of at least one rescue criterion starting at the Month 6 visit through to the Month 12 visit
- Number of Times That at Least One Rescue Criterion is Met [ Time Frame: Baseline through 12 months ]Assessment of the number of monthly intervals that at least one rescue criterion is met
- Number of Treatments, Including Both Rescue and Scheduled Study Treatments, During the Study [ Time Frame: Baseline through 12 months ]Assessment of the number of treatments, including both rescue and scheduled study treatments, that occurred during the study
- Change From Baseline in Best-corrected Visual Acuity (BCVA) (ETDRS Letter Score) at All Visits [ Time Frame: Baseline through 12 months ]
BCVA = best corrected visual acuity; ETDRS = early treatment of diabetic retinopathy
BCVA ETDRS range = 0 (worst) to 100 (best)
Assessment of change in BCVA (ETDRS letter score) from baseline at all visits
- Categorical Change From Baseline in BCVA (ETDRS Letter Score) at All Visits [ Time Frame: Baseline through 12 months ]
BCVA = best corrected visual acuity; ETDRS = early treatment of diabetic retinopathy
BCVA ETDRS range = 0 (worst) to 100 (best)
Assessment of categorical change in BCVA (ETDRS letter score) from baseline at all visits
- Frequency of Subjects With BCVA Worse Than 20/200 (Snellen Equivalent) at All Visits [ Time Frame: Baseline through 12 months ]
Assessment of the frequency of subjects with BCVA worse than 20/200 (Snellen equivalent) at all visits
A vision score of 20/20 is considered normal. A vision score of 20/200 is considered legally blind.
- Change From Baseline in Central Subfield Thickness (CST) (μm) at All Visits [ Time Frame: Baseline through 12 months ]
CST = central subfield thickness
Assessment of change in CST (μm) measurement from baseline at all visits
- Frequency of Subjects With Absence of Exudation (Intra-/Sub-retinal Fluid/Cystoid Edema) at at All Visits [ Time Frame: Baseline through 12 months ]Assessment of the frequency of subjects with absence of exudation (intra-/sub-retinal fluid/cystoid edema) at all visits
