Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The clinical trial is aimed to evaluate the anti-neovascular effect of KDR2-2 suspension eyedrop in the treatment of neovascular glaucoma. Fourty subjects would receive either 0.96 or 3.84 mg/per day/eye, in a QID fashion, ×7 days (those without complications can continue to 28 days). The anti-neovascular effect of KDR2-2 on iris neovascularization would be evaluated at day 1, day 7, day 14, day 28 after KDR2-2 usage.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Neovascular glaucoma (NVG) has a high blinding rate and poor prognosis. Anti-glaucoma surgery is the main stake of saving visual function and relieving pain, but the proliferation of iris neovascularization (NVI) makes it difficult to treat NVG. Normally, the patients need an intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents prior to glaucoma surgery to control the NVI proliferation.

KDR2-2, a novel small-molecule tyrosine kinase inhibitor targeting VEGF receptor 2 (VEGFR2), has demonstrated anti-neovascular effect without obvious side-effects or complications in animal studies and a Phase I clinical trial (NCT04620109). In this study, 40 patients with NVG will be included to evaluate the effectiveness of KDR2-2 suspension eyedrop on NVI in NVG eyes. The included subjects would receive either 0.96 or 3.84 mg/day/eye, in a QID fashion, ×7 days (those without complications can continue to 28 days).

This study aims to and propose a novel, non-invasive and more compliant method for the treatment of NVG.
