VEGF trap-eye for diabetic macular oedema
VEGF Trap is a human recombinant fusion protein consisting of the binding domains of VEGF receptors and Fc domain of IgG. Compared with ranibizumab, VEGF Trap has a longer half-life after intraocular injection, a higher binding affinity to VEGF-A, and binds other members of the VEGF family. Do et al assessed the safety and bioactivity of a single intravitreal injection of VEGF Trap-Eye (4.0 mg) in five subjects with diabetic macular oedema. No ocular toxicity was observed.
