EYE-RES-104 is a randomized, dose-masked study of intravitreal EYE103 in participants with neovascular age-related macular degeneration (NVAMD) or macular edema following branch retinal vein occlusion (BRVO).

The study will consist of 4 patient cohorts, with participants in each cohort randomized (1:1) to either a low dose of EYE103 via IVT or a high dose of EYE103 via IVT. 40 participants will be enrolled in each cohort. Enrollment timing for each cohort will be sequenced into specific arms of the study at the Sponsor's discretion.

All participants in the study will receive a total of 3 injections of EYE103 into the study eye, spaced at 4 weeks apart. All participants will return at designated time points following each injection for safety and efficacy assessments. The Week 12 Visit will serve as the end of study visit for all participants.

EYE-RES-104 is a randomized, dose-masked study of intravitreal EYE103 in participants with neovascular age-related macular degeneration (NVAMD) or macular edema following branch retinal vein occlusion (BRVO).

The study will consist of 4 patient cohorts, with participants in each cohort randomized (1:1) to either a low dose of EYE103 via IVT or a high dose of EYE103 via IVT:

• one cohort of 40 treatment naïve NVAMD participants will be randomized (1:1) to 1 of the 2 doses of EYE103 (as monotherapy),
• one cohort of 40 incomplete responder (IR) NVAMD participants will be randomized (1:1) to 1 of the 2 doses of EYE103 (as monotherapy),
• one cohort of 40 IR NVAMD participants will be randomized (1:1) to 1 of the 2 doses of EYE103, to be administered in combination with aflibercept 2.0 mg
• one cohort of 40 treatment naïve BRVO participants will be randomized (1:1) to 1 of the 2 doses of EYE103 (as monotherapy)

Enrollment timing for each cohort will be sequenced into specific arms of the study at the Sponsor's discretion.

All participants in the study will receive a total of 3 injections of EYE103 into the study eye, spaced at 4 weeks apart. IR NVAMD participants in the combination therapy cohort will also receive an injection of aflibercept 2.0 mg in the study eye on Day 1.

All participants will be assessed for safety and efficacy at injection visits. Treatment naïve NVAMD participants and IR NVAMD participants in the monotherapy cohort will also return 2 weeks after each injection visit for safety and efficacy assessments. Depending on the cohort, participants will be evaluated every 2 weeks or every 4 weeks, including measurement of ETDRS BCVA, examination by slit-lamp biomicroscopy, fundoscopy, and SD-OCT. Among other parameters, SD-OCT will be used to measure central subfield thickness (CST) in microns. The Week 12 Visit will serve as the end of study visit for all participants.
