Description of intervention(s) / exposure
Treatment: Drugs - Aflibercept (Eylea, BAY86-5321)

Experimental: Intravitreal (IVT) aflibercept - Participants with macular edema secondary to CRVO were treated with the study drug intravitreal aflibercept


Treatment: Drugs: Aflibercept (Eylea, BAY86-5321)
The recommended dose for intravitreal aflibercept was 2 mg equivalent to 50 µL. Study treatment was administered at baseline and at monthly intervals until stabilization of disease. When stability was achieved, the treatment interval could be extended based on visual and anatomic outcomes as judged by the treating investigator.

Can healthy volunteers participate?
No
Key exclusion criteria
- Previous PRP or macular laser photocoagulation in the study eye.

excluded.

- Prior systemic anti-VEGF or corticosteroid therapy, investigational or approved,
within the last 3 months before the first dose in the study.

- Previous use of intraocular corticosteroids in the study eye at any time or use of
periocular corticosteroids in the study eye within 12 months prior to Day 1.

- Any active intraocular, extraocular, and periocular inflammation or infection in
either eye within 4 weeks of screening.

- Any history of allergy to povidone iodine.

- Known serious allergy to the fluorescein sodium for injection in angiography.

- Presence of any contraindications indicated in the EU commission/locally approved
label for IVT aflibercept: hypersensitivity to the active substance IVT aflibercept or
to any of the excipients; active or suspected ocular or periocular infection; active
severe intraocular inflammation.

Summary
Brief summary
Central retinal vein occlusion (CRVO) occurs when the main blood vessel that transports blood
away from the retina (the very back portion of the eye) becomes blocked, causing the leakage
of fluid into the retina and thereby causing a swelling of the macula (the portion of the
retina responsible for fine vision). This swelling is called macular edema. When the macula
swells with fluid, central vision becomes blurry. The study drug aflibercept has been shown
to reduce the amount of fluid and blood leaked into the retina. It can help to stabilize, and
in many cases, improve the vision loss related to CRVO. Aflibercept has been approved for the
treatment of macular edema secondary to CRVO in the United States (US), European Union (EU),
Japan, and other countries.

The study was considered research because, although the study drug was already on the market
for macular edema secondary to CRVO, there were no studies available that addressed the
questions of what were useful intervals for treating and assessing patients, how did they
differ among patients, and how were criteria applied for retreatment. The purpose of this
study was to evaluate the effectiveness, treatment interval, and safety of the treatment
regimen (pattern for administering treatment) in subjects with macular edema secondary to
CRVO. In addition, this study explored new imaging methods for assessing the affected eye.
