This is a phase 3, multicenter, randomized, masked, controlled, parallel group study of 49 week-duration in treatment naïve subjects with RVO.

Primary Outcome Measures

Name	Time	Method
Main Objective: To demonstrate that suprachoroidally injected CLS-TA in combination with an intravitreally injected anti-VEGF agent is superior to an intravitreally injected anti-VEGF agent alone using a best corrected visual acuity (BCVA) outcome measure. ;Secondary Objective: • To determine the effect of suprachoroidally injected CLS-TA in combination with an intravitreally injected anti-VEGF agent on mean change from Baseline in BCVA<br>• To determine the effect of suprachoroidally injected CLS-TA in combination with an intravitreally injected anti-VEGF agent on mean change from Baseline in central subfield thickness <br>;Primary end point(s): Proportion of subjects demonstrating = 15 letter improvement from Baseline in Early Treatment of Diabetic Retinopathy Study (ETDRS) BCVA at Visit 4 (Month 2).;Timepoint(s) of evaluation of this end point: during treatment period.

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): • Mean change from Baseline (Visit 2, Day 0) in BCVA at Visit 4 (Week 8) and Visit 8 (Week 24)<br>• Mean change from Baseline (Visit 2, Day 0) in CST at Visit 4 (Week 8) and Visit 8 (Week 24)<br>;Timepoint(s) of evaluation of this end point: during treatment period.
