Vascular Endothelial Growth Factor (VEGF) Trap-Eye: Investigation of Efficacy and Safety in Central Retinal Vein Occlusion (CRVO)
|Macular Edema Secondary to Central Retinal Vein Occlusion||Biological: VEGF Trap-Eye 2.0mg Drug: Sham||Phase 3|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||A Randomized, Double Masked, Controlled Phase 3 Study of the Efficacy, Safety, and Tolerability of Repeated Intravitreal Administration of Vascular Endothelial Growth Factor Trap-Eye in Subjects With Macular Edema Secondary to Central Retinal Vein Occlusion|
- Percentage of Participants Who Gained at Least 15 Letters in BCVA at Week 24 as Measured by ETDRS Letter Score [ Time Frame: Baseline and at Week 24 ]
Percentage values indicate the number of subjects in each arm who were able to read an additional 15 letters or more at Week 24 compared to baseline.
Defined study baseline range of ETDRS Best Corrected Visual Acuity letter score of 73 to 24 letters (= Acuity of 20/40 to 20/320) in the study eye; a higher score represents better functioning.
- Change From Baseline in BCVA as Measured by ETDRS Letter Score at Week 24 - Last Observation Carried Forward (LOCF) [ Time Frame: Baseline and at Week 24 ]Defined study baseline range of ETDRS Best Corrected Visual Acuity letter score of 73 to 24 (= Acuity of 20/40 to 20/320) in the study eye; a higher score represents better functioning.
- Change From Baseline in Central Retinal Thickness (CRT) at Week 24 - LOCF [ Time Frame: Baseline and at Week 24 ]
- Percentage of Participants Progressing to Any of the Following: Anterior Segment Neovascularization, New Vessels of the Disc (NVD) or New Vessels Elsewhere (NVE) During the First 24 Weeks [ Time Frame: Baseline to Week 24 ]
- Change From Baseline in the NEI VFQ-25 in Total Score at Week 24 (LOCF) [ Time Frame: Baseline and at Week 24 ]The NEI VFQ-25 assesses visual function and quality of life. Total score ranges from 0-100 with a score of 0 being the worst outcome and 100 being the best outcome. The NEI VFQ questionnaire is organized as a collection of subscales which are all scored from 0-100. To reach the overall composite score, each sub-scale score is averaged in order to give each sub-scale equal weight.
