Neovascular Age-Related Macular Degeneration (nAMD) Wet AMD

This is a Phase II, randomized, open-label, active-controlled study designed to evaluate the preliminary efficacy and safety of a single subretinal administration of JWK001 at different dose levels in patients with neovascular age-related macular degeneration.

The purpose of this study is to evaluate safety, effectiveness and durability of a gene therapy called Ixo-vec (Ixoberogene soroparvovec) when administered to the contralateral (second) eye of adult participants (≥ 50 years of age) who have been diagnosed with bilateral neovascular (wet) age related macular degeneration (nAMD). The study will enroll adults with nAMD in both eyes, including participants who previously received Ixo-vec treatment in one (initial) eye and/or participants who will receive Ixo-vec treatment for the first time. This study focuses on how the treatment works when both eyes are treated at different times and how effective and long-lasting Ixo-vec treatment is in the second (contralateral) eye. Participants will receive a single administration of Ixo-vec in the contralateral eye and will be followed for approximately 5 years to evaluate safety, efficacy and durability of contralateral treatment. Secondary objectives include assessments that will evaluate clinical activity, including visual and anatomic outcomes, as well as the need for supplemental anti-VEGF therapy. The study is intended to provide additional information on the safety, tolerability, and use of Ixo-vec in bilateral treatment.

Primary objective: • To evaluate the change in aqueous humor vascular endothelial growth factor A (VEGF-A) levels after 2 months of initial treatment with 8 mg Aflibercept in treatment-naïve nAMD patients. Secondary objectives: • To assess the efficacy, safety, and biomarker changes of 8 mg Aflibercept using a modified fixed-interval dosing regimen over 12 months in treatment-naïve nAMD patients.
