Inclusion Criteria

Inclusion Criteria:

  • Patient diagnosed with macular edema due to RVO (either BRVO or CRVO, non-ischemic)
  • Retinal thickness ≥ 300 μm by SD-OCT in the central 1 mm macular subfield of the study eye at the Screening visit
  • BCVA score of 19 to 73 letters (approximately 20/400 to 20/40 Snellen equivalent) in the study eye measured by ETDRS method at Screening
  • < 3 months of macular edema duration
  • Treatment-naive patients (ie, have not previously received any treatment for macular edema secondary to RVO)
Exclusion Criteria
  • Uncontrolled systemic disease
  • Presence of/history of any ocular condition other than macular edema that affects visual acuity (eg, cataract, severe macular ischemia, foveal atrophy, age-related macular degeneration, uveitis or other ocular inflammatory disease, neovascular glaucoma, Irvine-Gass syndrome, prior macular detachment)
  • Any of the following ≤ 3 months before study entry or anticipated need within the coming 3 months:
  • Intraocular surgery
  • Laser photocoagulation
  • Intraocular injection
  • Periocular steroid injection
  • Vitrectomized eye
  • Aphakic eyes with ruptured posterior lens capsule or presence of an ACIOL, iris or transscleral fixated intraocular lens
  • History of marked IOP elevation in response to steroid treatment that (a) required IOP-lowering treatment, (b) resulted in a >10 mm Hg increase in IOP from predose, or (c) resulted in IOP >25 mm Hg
  • History of glaucoma or ocular hypertension (IOP > 21 mm Hg), or optic nerve head change consistent with glaucoma damage, and/or glaucomatous visual field loss in the study eye (patients with a history of previous angle closure that has been successfully treated with either a laser or surgical peripheral iridotomy [PI] are allowed as long as the visual fields have been stable for > 1 year prior to study entry and the patient has been and can be safely dilated).
  • Any active ocular infection (i.e., bacterial, viral, parasitic, or fungal) in either eye at the Screening visit
  • Female patients who are pregnant, nursing, or planning a pregnancy, or who are of childbearing potential and not using a reliable means of contraception
  • Any condition that may interfere or preclude participation in the study
  • Use of systemic steroids (e.g., oral, intravenous, intramuscular, epidural, rectal, or extensive dermal) within 1 month prior to Baseline or anticipated use at any time during the study (inhaled, intranasal, and intra-articular/intrabursal corticosteroids are allowed)
  • Use of immunosuppressants, immunomodulators, antimetabolites, and/or alkylating agents within 3 months prior to Baseline or anticipated use at any time during the study
  • Use of warfarin or heparin within 2 weeks prior to Baseline or anticipated use within the study period
  • Known allergy, hypersensitivity or contraindication to the study medication, its components, fluorescein or povidone iodine
  • Current enrollment in another drug or device study within 30 days prior to Baseline

Primary Outcome Measures
NameTimeMethod
Mean change in visual acuity from BaselineAt Month 6

Determined by best corrected visual acuity (BCVA)

Proportion of patients with a BCVA improvement of 15 letters or more compared to BaselineAt Month 6

Measured using the ETDRS visual acuity protocol

BCVA average change from Baseline in area under the curve (AUC) analysisAt Month 6
Secondary Outcome Measures
NameTimeMethod
Mean change from Baseline in BCVAAfter first follow-up visit, at each injection, and at Month 12
Mean change from Baseline in Central Retinal Thickness (CRT)At Months 6 and 12
Mean change from Baseline in the National Eye Institute (NEI) Visual Function Questionnaire (VFQ)-25At Months 6 and 12

25 vision-targeted questions representing 11 vision-related constructs, plus an additional single-item general health rating question. All items are scored so that a high score represents better functioning. Original numeric values from the survey will be recoded with the worst and best possible scores set at 0 and 100 points, respectively. In this format, scores represent the achieved percentage of the total possible score, e.g. a score of 50 represents 50% of the highest possible score.
