Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Phase 2b, multicenter, visual examiner-masked, randomized active-controlled, parallel-arm design study to evaluate the safety and duration of repeated IVT injections of 3 dose levels of GB-102 compared with aflibercept.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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
