One year outcomes of intravitreal faricimab for treatment Naïve neovascular AMD and associations with baseline aqueous humor cytokines.

This study investigated the one-year real-world clinical outcomes of intravitreal faricimab (IVF) in treatment-naïve neovascular age-related macular degeneration (nAMD) and its association with aqueous humor cytokine profiles. Thirty-four eyes of 32 nAMD patients, who received initial IVF at Jichi Medical University were included. These eyes showed significant improvements in central retinal subfield thickness (CST), central choroidal thickness (CCT), and best-corrected visual acuity (BCVA) one year post-IVF (all P < 0.01). Among 24 measurable cytokines, only VEGF-A was significantly higher in eyes with a dry macula at week 16 (P = 0.0030). Three cytokines were significantly higher in eyes with longer injection interval. Higher levels of galectin-1 and VCAM-1, and lower levels of P-selectin, were correlated with greater CST reduction (P = 0.020, 0.0061, and 0.012, respectively). Conversely, five cytokines including Ang-1 were correlated with greater BCVA improvement (all P < 0.05). In conclusion, an anatomical perspective faricimab demonstrated anatomical efficacy for VEGF-driven nAMD in the loading phase, while multiple cytokines associated with vascular instability or fibrosis appear to contribute to its durability. Notably, Ang-1 may be linked to visual improvement, suggesting that the neurotrophic effects of Ang-1 could be enhanced by Ang-2 inhibition.
