Brief Summary:
The study is intended to characterize the clinical benefit regarding safety and efficacy of a long term treatment with Lucentis in comparison with Ozurdex over an additional 6 months and a 3-month follow-up period, following the initial 6-month treatment in the respective core studies CRFB002EDE17 (NCT01396057) and CRFB002EDE18 (NCT01396083).

Arm Intervention/treatment
Experimental: Ranibizumab (Arm A)

The PRN injection scheme applied in the core study will also be followed during this extension study:

Patients should be monitored monthly (starting at V1E) for VA and treatment is to be resumed when monitoring indicates loss of VA due to disease activity. Monthly injections should then be administered until stable VA is reached again for 3 consecutive monthly assessments (implying a minimum of 2 injections during stable VA). The interval between 2 doses should not be shorter than 1 month

Biological: RFB002
0.5 mg/0.05 mL solution to be injected intravitreally. Ranibizumab was formulated as a sterile solution aseptically filled in a sterile glass vial. Each vial contained ranibizumab in an aqueous solution (pH 5.5) with histidine, trehalose and polysorbate 20.

Sham Comparator: Dexamethasone (Arm B)
A PRN re-treatment scheme will be applied for the Ozurdex arm during this extension study, i.e. patients may receive an implant at V1E or later as needed: Patients should be monitored monthly and if there is a decline from stable VA stability due to macular edema patients will receive another intravitreal implant. (700 µg; long acting release (LAR)) given that in the opinion of the investigator the patient would benefit from the re-treatment. However, a minimum period of 5 months in between implantations is required.
Drug: Dexamethasone
Ozurdex (Dexamethasone): intravitreal implant as per commercial label (700 µg Dexamethasone; Dexamethasone was formulated as a rod shaped implant to be inserted into the eye by an applicator. The implant as well as the respective applicator were suitable for single use only. Dexamethasone had to be stored according to label instructions and it had to be kept in a secure locked facility

Primary Outcome Measures :
  1. Number of Participants With Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 6 months ]
    The number of participants who experienced Adverse events, serious AE and death

Secondary Outcome Measures :
  1. Raw Mean Best Corrected Visual Acuity (BCVA) by Treatment Group [ Time Frame: Baseline, 6 months and 12 months ]
    Best-Corrected Visual Acuity (BCVA) letters was measured using Early Treatment Diabetic Retinopathy Study (EDTRS)-like chart while participants were in a sitting position at a testing distance of 4 meters. An ETDRS visual acuity score of 85 is approximately 20/20. The range of BCVA (EDTRS) is 0 to 100 letters. A positive change from baseline of BCVA indicates improvement

  2. Percentage of Patients Gaining / Losing ≥ 15 / 10 / 5 Letters at Month 12 Compared to Baseline [ Time Frame: 12 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 percentage of participants who were gaining/losing ≥15, 10 or 5 more letters of visual acuity at month 12 as compared with baseline

  3. Change in Central Subfield Thickness (CSRT) From Baseline to Month 12 [ Time Frame: Baseline , Month 12 ]
    High Resolution OCT was performed at every study visit by Spectral Domain OCT (if not available Time Domain OCT was acceptable) and the images were transferred to a digital video disc. These assessments were performed by trained and adequately qualified experts at the sites and prior to any study drug administration. CSFT is the average retinal thickness of the circular area with 1 mm diameter around the foveal center.

  4. Change of Foveal Center Point Thickness (FCPT) From Baseline to Month 12 [ Time Frame: Baseline, Month 12 ]
    FCPT (foveal center point thickness) was assessed by central reading center to ensure error- corrected measurements of retinal thickness and volumes,

  5. Change in Mean Visual Function Questionnaire (VFQ-25) [ Time Frame: Baseline, 12 months ]
    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.

  6. Change in SF-36 Summary Scores [ Time Frame: Baseline, month 12 ]
    The SF-36 measures the impact of disease on overall quality of life and consists of eight subscales (physical function, pain, general and mental health, vitality, social function, physical and emotional health) which can be aggregated to derive a physical-component summary score and a mental-component summary score. Scores for each subscale range from 0 to 10, and the composite scores range from 0 to 100, with higher scores indicating better health. A positive change from Baseline score indicates improvement in quality of life.

  7. Change in Euro Quality of Life Questionnaire (EQ-5D) VAS Summary Scores [ Time Frame: Baseline, month 12 ]
    The Euro Quality of Life Questionnaire (EQ-5D) standardized instrument was utilized to measure health outcomes related to mobility, self care, usual activities, pain/discomfort, and anxiety/depression. Participants self-rate their health on a visual, vertical analogue scale from 0 to 100 where the endpoints are labeled "Best imaginable health state" (100) and "worst imaginable health state" (0).

  8. Time to the First Retreatment of Both Treatment Arms [ Time Frame: 6 months ]
    Time to the first retreatment
