Recent evidence has suggested that the use of norrin mimetics targeting both frizzled-4 (FZD4) and low-density lipoprotein receptor-related protein 5 (LRP5) may be highly effective at modulating retinal vascular leakage. When combined with an anti-VEGF therapy, it was hypothesized to have an additive benefit potential for treating retinal vascular disorders.
Glaucoma is a leading cause of blindness and is characterized by the death of retinal ganglion cells (RGCs). Genetic screening data have identified dual leucine zipper kinase (DLK) and leucine zipper kinase (LZK) as important mediators of RGC death.
Innovent Biologics Inc.’s efdamrofusp alfa (IBI-302) met the primary endpoint in phase II, showing a gain of 10 or more letters in visual acuity from baseline at one year in Chinese patients with neovascular age-related macular degeneration.
