September 21, 2016 updated by: Novartis Pharmaceuticals

A 6-month Multicenter, Randomized, Double-masked Phase IIIb-study Comparing the Efficacy and Safety of Ranibizumab Intravitreal Injections Versus Dexamethasone Intravitreal Implant in Patients With Visual Impairment Due to Macular Edema Following Central Retinal Vein Occlusion (CRVO)

This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant® after 6 months of treatment. In the study arm Lucentis will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mean Average BCVA Change From Month 1 Through Month 6 to Baseline
Time Frame: Baseline, month 6
the average of the changes in BCVA (letters) from baseline to any post-baseline visit, i.e. the mean of six differences to baseline for the six post-baseline visits at month 1 to 6. BCVA score was based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters. An ETDRS visual acuity score of 85 is pproximately 20/20. An increased score indicates improvement in acuity
Baseline, month 6

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to Achieve a Significant Improvement ≥ 15 Letters
Time Frame: Baseline, month 6
The time was analyzed by the Kaplan-Maier-Method, adjusting the calculation for dropouts
Baseline, month 6
Change Over Time of the Central Retinal Thickness (CRT)
Time Frame: Baseline, month 6
Retinal thickness was measured using Optical Coherence Tomography (OCT). The images were reviewed by a central reading center to ensure a standardized evaluation
Baseline, month 6
Changes in the Quality of Life According to the Short Form (36) Health Survey (SF-36)Questionnaires
Time Frame: Baseline, month 6
SF-36 summary measures are norm-based scores with mean = 50 and SD = 10. Higher scores indicate better health
Baseline, month 6
Changes in the Quality of Life According to Euro Quality of Life (EQ-5D) Questionnaires
Time Frame: Baseline, month 6
The EQ-5D visual analog scale ranges from 0 to 100, 0 representing the worst and 100 the best imaginable health state.
Baseline, month 6
Mean BCVA Change at Month 6
Time Frame: Baseline, month 6
The analysis was performed by an analysis of covariance (ANCOVA) model with average change in BCVA (letters) from Visit 1 through Visit 6 as dependent variable, and with the factors center, treatment and covariate baseline BCVA as predictors
Baseline, month 6
Number of Patients Gaining / Losing ≥ 15 / 10 / 5 Letters
Time Frame: Baseline, 6 month
BCVA score was based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters. An ETDRS visual acuity score of 85 is approximately 20/20. An increased score indicates improvement in acuity. This outcome assessed the number of participants who gained 15, 10 or 5 more letters of visual acuity at month 6 as compared with baseline
Baseline, 6 month
Change Over Time in BCVA
Time Frame: Baseline, month 6
The analysis was performed by an analysis of covariance (ANCOVA) model with average change in BCVA (letters) from Visit 1 through Visit 6 as dependent variable, and with the factors center, treatment and covariate baseline BCVA as predictors
Baseline, month 6
Changes in the Quality of Life According to the National Eye Institute Visual Function Questionnaire (NEI-VFQ 25) Questionnaires
Time Frame: Baseline, month 6
The VFQ-25 composite and subscale scores range from 0 to 100, a higher score indicating better functioning. The 12 subscales in the VFQ-25 are general health, general vision, ocular pain, near activities, distance activities, social function, mental health, role difficulties, dependency, driving, color vision, and peripheral vision. The scores on the subscales were added together for a total score, which ranged from 0 to 100. A higher score indicated improvement in quality of life due to vision function
Baseline, month 6
Increase Rate of the Internal Ocular Pressure (IOP ) : Patients With ≥10% Increase in IOP Compared to Baseline
Time Frame: Baseline, month 6
The proportion of patients with ≥ 10% increase in Internal Ocular Pressure (IOP) compared to baseline at any post-baseline visit.
Baseline, month 6
