Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A two part, multi-center study consisting of a Phase 1b open label, sequential dose escalation followed by a Phase 2a randomized, double-masked, dose expansion evaluating OPT-302 in combination with aflibercept in participants with persistent central-involved Diabetic Macular Edema.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study OPT-302-1003 was designed as a 2-part, multicenter study consisting of a Phase 1b open-label, sequential dose escalation followed by a Phase 2a randomized, parallel-group, sham-controlled, double-masked, dose-expansion evaluating intravitreal OPT-302 in combination with aflibercept in participants with persistent central-involved diabetic macula edema.
