0.5 mg Conbercept
Subjects received 0.5 mg conbercept intravitreal injection at Day 1, Week 4 and Week 8 (three injection loading dose), and treated every eight weeks thereafter (0.5 mg, q8w) through Week 36. At the Week 40 visit, the criteria-based pro re nata (PRN) approach will begin through the end of the treatment period at Week 92, for a total of 92 weeks treatment in the study eye.
