To determine the efficacy of vascular endothelial growth factor (VEGF) Trap-Eye injected into the eye on vision function in subjects with macular edema as a consequence of central retinal vein occlusion.

Official Title

A Randomized, Double-masked, Sham-controlled Phase 3 Study of the Efficacy, Safety and Tolerability of Repeated Intravitreal Administration of VEGF Trap-Eye in Subjects With Macular Edema Secondary to Central Retinal Vein Occlusion (CRVO)

Conditions

Retinal Vein Occlusion

Study Type

Interventional

Study Design

Randomized, Parallel Assignment,  Double Blind (Subject, Investigator, Outcomes Assessor), Treatment, Safety/Efficacy Study

Further Details

Primary Outcome Measures:

  • The proportion of subjects who gain at least 15 letters in BCVA on the EDTRS chart compared with baseline at the Week 24 endpoint
    [ Time Frame: Week 24 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

  • Change from baseline in BCVA score
    [ Time Frame: week 24 ] [ Designated as safety issue: No ]
  • Absolute change from baseline in central retinal thickness, assessed by OCT
    [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
  • Proportion of subjects progressing to anterior segment neovascularization, neovascularization of the optic disc (NVD), or neovascularization of the retina elsewhere (NVE) requiring pan-retinal photocoagulation
    [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
  • Change in the NEI-VFQ-25 total score from baseline
    [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
  • Change in the EQ-5D score from baseline
    [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
