Official title: An Exploratory Single Site, Open Label, Randomized, Controlled Study to Evaluate Plasma Vascular Endothelial Growth Factor Levels After Intravitreal Injection of Ranibizumab (Lucentis) and Conbercept (Langmu) for nAMD

Status Completed

Clinical Trial Summary

An exploratory single site, open label, randomized, controlled study evaluated plasma vascular endothelial growth factor levels after intravitreal injection of ranibizumab (Lucentis) and conbercept (Langmu) for neovascular age-related macular degeneration

Clinical Trial Description

This prospective, randomized, open label study enrolled patients with neovascular AMD who were naïve to anti-VEGF therapy or have not received intravitreal anti-VEGF therapy for the previous 3 months. Patients were randomized in two treatment arms for 3 months:

• Study arm 1: Three monthly injections of 0.5mg Ranibizumab

• Study arm 2: Three monthly injections of 0.5mg Conbercept Blood sample (plasma/serum) was collected at baseline (pre-dose), 3h post-injections and days 1, 3, 7 and 28, following doses 1 and 3 for PK and systemic VEGF analysis. The lab staff was blinded for treatment allocation.

Plasma VEGF concentration was measured by a blinded laboratory using Quantikine® ELISA kits. Serum ranibizumab and conbercept concentration will be determined using validated ELISA assay.

The study was divided into 2 stages: the 1st initial feasibility stage with 6 patients per arm (12 patients in total) to verify SD for sample size justification and 2nd stage to confirm the findings with justified sample size. ;
