Brief summary
The goal of this study is to evaluate the overall safety and efficacy of LX102 gene therapy for nAMD.
Detailed description
In this Phase 2, multi-center, randomized controlled study, subjects will be randomized to receive one of the two dose levels of LX102 (n=20 for each dose level), or aflibercept (n=10). Safety, tolerability, and efficacy will be evaluated for a period of approximately 1 year from baseline.
Interventions
LX102: AAV-based gene therapy comprised of codon-optimized sequence encoding VEGF-trap
Commercially available Active Comparator

Exclusion criteria
1. CNV or macular edema in the study eye secondary to diseases other than nAMD. 2. Retinal detachment, uveitis, uncontrolled glaucoma in the study eye, or any condition preventing visual acuity improvement. 3. Absence of RPE tear at Screening. 4. Acute coronary syndrome, myocardial infarction or coronary artery revascularization, CVA, TIA in the last 6 months. 5.
