Brief Summary:
This Phase 3, multicenter, randomized, masked, controlled, parallel group study is designed to demonstrate that suprachoroidal (SC) CLS-TA administered with intravitreal (IVT) anti-VEGF agent in subjects with treatment naive RVO is superior to IVT anti-VEGF agent used alone.

Condition or disease Intervention/treatment Phase
Macular Edema Retinal Vein Occlusion Drug: suprachoroidal CLS-TA Drug: suprachoroidal sham Drug: Lucentis or Avastin Phase 3
