A Multi-Center, Two-Stage, Open-Label Phase I and Randomized, Active Controlled, Masked Phase II Study to Evaluate the Safety and Efficacy of Intravitreal Implantation of NT-503-3 Encapsulated Cell Technology Compared With Eylea for the Treatment of Recurrent CNV Secondary to AMD

Prospective, multi-center 2-stage study. Stage 1 (Phase I) is open-label with all patients
treated with the NT-503-3 ECT implant. Stage 1 (Phase I) patients will undergo explantation
at year 2. Those who, in the opinion of the investigator, are still candidates for continued
anti-VEGF therapy will be re-implanted with a new NT-503-3 investigational product and
followed for an additional 12 weeks before study exit. Stage 2 (Phase II) is a separate,
randomized, masked phase during which eligible patients will be randomized to the NT-503-3
group or the control group.

Clinical Hypotheses:

- NT-503-3 ECT is comparable to Eylea® injected intravitreally every 8 weeks in the
prevention of vision loss due to recurrent CNV secondary to AMD

- NT-503-3 ECT has an acceptable safety profile


Key Inclusion Criteria:

- Diagnosis of Active (recurrent or persistent) subfoveal CNV lesions secondary to AMD
in the study eye

- Prior Intravitreal Anti-VEGF injections

Key Exclusion Criteria:

- Significant subretinal hemorrhage

- Significant Scar and/or, fibrosis

- Suspected polypoidal choroidopathy, or pigment epithelial tears or rips

- Inadequate response to anti-VEGF therapy
