Clearside Biomedical CLS1003-301

A Randomized, Masked, Controlled Trial to Study the Safety and Efficacy of Suprachoroidal CLS-TA in Conjunction with Intravitreal Aflibercept in Subjects with Retinal Vein Occlusion

Sponsor:  Clearside Biomedical, Inc.

Principal Investigator: Jonathan Chang, MD

Study Coordinator: Kris Dietzman


The purpose of this study is to demonstrate the safety and efficacy of SC CLS-TA in conjunction with IVT aflibercept in subjects with RVO.

This is a Phase 3, multicenter, randomized, masked, controlled, parallel group study of 12 months duration in treatment-naïve subjects with RVO. This study is projected to enroll approximately 460 subjects, randomly assigned 1:1 to one of two treatment groups stratified by disease (BRVO, CRVO).

The study design includes 12 clinic visits over approximately 50 weeks

Study Drug:

Active: IVT aflibercept (2 mg/0.05 mL) + CLS-TA (4 mg/100 μL) SC injections

Control: IVT aflibercept (2 mg/0.05 mL) injection + sham SC procedure
