Patients in the VISTA-DME trial were randomized to receive either EYLEA 2Q4 (n=155), EYLEA 2Q8 (n=152), or the comparator treatment of laser photocoagulation (n=154).
After two years, patients receiving EYLEA 2Q4 had a mean change from baseline in BCVA of 11.5 letters (12.5 letters at 52 weeks). Patients receiving EYLEA 2Q8 had a mean change from baseline in BCVA of 11.1 letters (10.7 letters at 52 weeks). Patients in the laser photocoagulation treatment group had a mean change from baseline in BCVA of 0.9 letters (0.2 letters at 52 weeks).
"These data showed that treatment with EYLEA in this trial improved vision and maintained the improvement over two years in patients with diabetic macular edema," said
In this trial, EYLEA was generally well tolerated with a similar overall incidence of adverse events (AEs), ocular serious AEs, and non-ocular serious AEs across the EYLEA treatment groups and the laser control group. AEs were typical of those seen in other studies in patients with diabetes receiving intravitreal anti-VEGF therapy. The most frequent ocular AEs observed in the VISTA-DME trial included conjunctival hemorrhage, eye pain, and vitreous floaters. The most frequent non-ocular AEs included hypertension, anemia, and urinary tract infection. Arterial thromboembolic events as defined by the Anti-Platelet Trialists' Collaboration (non-fatal stroke, non-fatal myocardial infarction, and vascular death) were similar across the treatment groups and the laser control group with events occurring in 13 out of 155 patients in the EYLEA 2Q4 group, 11 out of 152 patients in the EYLEA 2Q8 group, and 9 out of 154 patients in the laser group. Eight out of 155 patients died in the EYLEA 2Q4 group, 4 out of 152 patients in the EYLEA 2Q8 group, and 3 out of 154 patients in the laser treatment group.
Full two-year data from the VISTA-DME trial will be presented at upcoming medical conferences. Two-year data from the similarly designed VIVID-DME trial are expected later in 2014. Both the VISTA-DME and the VIVID-DME trials will continue as planned up to 148 weeks.

About the EYLEA® (aflibercept) Injection Phase 3 DME Program

About Diabetic Macular Edema (DME)
DME is a common complication of Diabetic Retinopathy (DR), a disease affecting the blood vessels of the retina. Clinically significant DME occurs when fluid leaks into the center of the macula, the light-sensitive part of the retina responsible for sharp, direct vision. Fluid in the macula can cause severe vision loss or blindness.
DME is the most frequent cause of blindness in young and mid-aged adults. The treatable population for DME globally is estimated at about 6.2 million people. According to the
About EYLEA® (aflibercept) Injection for Intravitreal Injection
Vascular Endothelial Growth Factor (VEGF) is a naturally occurring protein in the body. In patients with diabetic macular edema (DME), hyperglycemia-induced vascular dysfunction and hypoxia result in elevated intraocular VEGF levels in the eye and resultant blood vessel permeability that leads to macular edema, which can result in vision loss.
EYLEA, known in the scientific literature as VEGF Trap-Eye, is a recombinant fusion protein, consisting of portions of human VEGF receptors 1 and 2 extracellular domains fused to the Fc portion of human IgG1 and formulated as an iso-osmotic solution for intravitreal administration. EYLEA acts as a soluble decoy receptor that binds VEGF-A and placental growth factor (PlGF) and thereby can inhibit the binding and activation of their cognate VEGF receptors.
IMPORTANT PRESCRIBING INFORMATION FOR EYLEA® (aflibercept) INJECTION IN
EYLEA® (aflibercept) Injection is indicated for the treatment of patients with neovascular (Wet) Age-related Macular Degeneration (AMD). The recommended dose for EYLEA is 2 mg administered by intravitreal injection every 4 weeks (monthly) for the first 12 weeks (3 months), followed by 2 mg once every 8 weeks (2 months). Although EYLEA may be dosed as frequently as 2 mg every 4 weeks (monthly), additional efficacy was not demonstrated when EYLEA was dosed every 4 weeks compared to every 8 weeks.
EYLEA is indicated for the treatment of patients with Macular Edema following Central Retinal Vein Occlusion (CRVO). The recommended dose for EYLEA is 2 mg administered by intravitreal injection every 4 weeks (monthly).
IMPORTANT SAFETY INFORMATION FOR EYLEA® (aflibercept) INJECTION
EYLEA® (aflibercept) Injection is contraindicated in patients with ocular or periocular infections, active intraocular inflammation, or known hypersensitivity to aflibercept or to any of the excipients in EYLEA.
Intravitreal injections, including those with EYLEA, have been associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering EYLEA. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately. Intraocular inflammation has been reported with the use of EYLEA.
Acute increases in intraocular pressure have been seen within 60 minutes of intravitreal injection, including with EYLEA. Sustained increases in intraocular pressure have also been reported after repeated intravitreal dosing with VEGF inhibitors. Intraocular pressure and the perfusion of the optic nerve head should be monitored and managed appropriately.
There is a potential risk of arterial thromboembolic events (ATEs) following use of intravitreal VEGF inhibitors, including EYLEA, defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause). The incidence of ATEs in the VIEW 1 and VIEW 2 wet AMD studies in patients treated with EYLEA was 1.8% during the first year. The incidence of ATEs in the COPERNICUS and GALILEO CRVO studies was 0% in patients treated with EYLEA compared with 1.4% in patients receiving sham control during the first six months.
The most common adverse reactions (5% or more) noted in the U.S. prescribing information for the approved indications of EYLEA were conjunctival hemorrhage, eye pain, cataract, vitreous detachment, vitreous floaters, and increased intraocular pressure.
Serious adverse reactions related to the injection procedure have occurred in < 0.1% of intravitreal injections with EYLEA including endophthalmitis, traumatic cataract, increased intraocular pressure, and vitreous detachment.
