a study to compare ql1207 to eylea® in subjects with wet age-related macular degeneration (wamd)

Conditions: Wet Age-related Macular Degeneration

Summary: this is a randomised, double-masked, parallel group, multicentre study to evaluate the efficacy and safety of ql1207 compared to eylea® in subjects with wet amd.

subjects will be randomised in a 1:1 ratio to receive either ql1207 or eylea® (administered via intravitreal \[ivt\] injection 2 mg \[0.05 ml\] every 4 weeks for the first 3 months (i.e., at weeks 0, 4, and 8), followed by 2 mg \[0.05 ml\] once every 8 weeks ) . subjects will be administered the study drug up to week 48, and the last assessment will be done at week 52.
