Sozinibercept

Sozinibercept (OPT 302; VGX-300) is a soluble form of VEGFR-3, potently inhibits the activity of VEGF-C/D, which are the proangiogenic factors, inhibiting angiogenesis and vascular leakage. Sozinibercept also inhibits diabetic retinal edema in rats.

Sozinibercept inhibits CNV lesion formation and vascular leakage in the mouse laser-induced model of choroidal neovascularization (CNV). Moreover, Sozinibercept exhibits comparable efficacy to Aflibercept in CNV mouse model^[1][2].
Sozinibercept (intravitreal injection; once every 4 wk for 4 months) shows selective inhibition of VEGF-C/D, and inhibits diabetic retinal edema induced by streptozotocin (STZ) in the rat model, and equivalent to inhibition of VEGF-A inhibitor (Aflibercept)^[3].
