`Purpose:: To determine the safety, tolerability, and bioactivity of a single dose (4.0mg) of
`intravitreal VEGF Trap in patients with diabetic macular edema (DME).
`Methods:: Five patients with DME, foveal thickness
` 250µm measured by optical
`coherence tomography (OCT) and ETDRS best-corrected visual acuity (BCVA) of
` 20/40 and
` 20/320 were administered a single intravitreal injection of 4 mg VEGF Trap at day 0.
`Safety assessments included eye examinations, vital signs, and laboratory tests. Measures
`of bioactivity included changes from baseline in BCVA, centerpoint retinal thickness (CRT),
`and leakage
`on uorescein angiography. Subjects were monitored for 6 weeks following
`VEGF Trap administration.
`Results:: Mean patient age was 65.2 years (range=56-75); 4 were Type 2 diabetics. Mean
`duration of diabetes prior to treatment was 26 years. All had received prior treatment for
`DME. No severe ocular or serious systemic adverse events related to study drug were
`noted. Mean baseline BCVA was 69 letters and mean baseline CRT was 407µm. Four
`patients had improvements in BCVA, ranging from 6 to 10 letters at 4 weeks post-injection.
`The mean decrease in centerpoint retinal thickness was 115µm at 4 weeks.
`Conclusions:: A single intravitreal dose of VEGF Trap was well-tolerated and led to a
`reduction in CRT and an improvement in BCVA. Although the number of subjects is small,
`preliminary evidence for bioactivity of VEGF Trap in patients with DME was detected.

`Additional studies are being planned to identify the potential therapeutic role of
`intravitreal VEGF Trap in DME.
