Neovascular (Wet) Age-related Macular Degeneration Clinical Trial
Official title:
A Multicenter, Randomized, Double-blind Phase III Clinical Study Comparing the Efficacy and Safety of BAT5906 and Ranibizumab (Lucentis®) in Patients With Neovascular Age-related Macular Degeneration
A non-inferiority design was used to conduct a randomized, double-blind, parallel-controlled multi-center study. A total of 488 subjects with neovascular (wet) age-related macular degeneration (w-AMD) were planned to be enrolled. Qualified subjects were divided into experimental group and control group in a 1:1 ratio, and stratified randomized according to the letter value of baseline period and whether the eyes had received anti-VEGF drug treatment. The experimental group received BAT5906 injection. The control group received Lucentis® treatment. Only 1 eye per subject was included in this study.

The experimental group received BAT5906 injection. The control group received Lucentis® treatment. Only 1 eye per subject was included in this study. The administration regimen was as follows: once every 4 weeks, 4mg BAT5906 or 0.5mg Lucentis® were injected intravitreal each time, the treatment period of the study was 48 weeks, a total of 13 administration times, the last follow-up was conducted at the 52nd week, the last visit did not require treatment, only efficacy and safety assessment, and blood samples were collected as required. Ophthalmic examination, vital signs, physical examination, and laboratory examination were performed for efficacy and safety assessment according to the test procedures specified in the protocol, and blood samples were collected for immunogenicity indicators. Change in best corrected visual acuity (BCVA) from baseline was assessed by ETDRS visual acuity chart at 4-week intervals. The primary efficacy measure was the change in BCVA from baseline at 52 weeks. Secondary efficacy measures were the change in best corrected visual acuity (BCVA) of the target eye from baseline and the change in macular fovea thickness (CRT) from baseline at weeks 12, 24, 36 and 48. Blood samples were collected according to the time points specified in the program, and the serum anti-drug antibody (ADA) was detected. Titer analysis and neutralizing antibody (Nab) analysis were performed on the samples confirmed as positive by ADA.
