What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are 4D-150 IVT (3E10 vg/eye), or EYLEA® (aflibercept) Injection 2 mg (0.05mL). The registry lists allocation as randomized. This Phase 3 study is evaluating the safety and how well it works of 4D-150 versus aflibercept in participants with neovascular age-related macular degeneration (nAMD).
They plan to enroll about 480 people at 126 sites. Taking part typically means an infusion or injection of a biologic plus check-ins.
