Faricimab reduces fluid in Neovascular Age-Related Macular Degeneration eyes, unravels study

Retrospective chart review was conducted on eyes with nARMD with persistent subretinal and/or intraretinal fluid despite previously receiving ≥15 injections with ≥2 different anti-VEGF agents. Best corrected visual acuity (BCVA) and optical coherence tomography (OCT) parameters were collected at baseline, initial post-injection visit, and most recent visit with OCT following last faricimab.

Nineteen eyes were included. Average logMAR BCVA was 0.47 ± 0.60 at baseline, 0.42 ± 0.47 at initial follow-up (p=0.38), and 0.51 ± 0.63 at final visit (p = 0.50). Average central subfield thickness (CST) was 310 ± 92 μm at baseline, 279 ± 88 μm at initial follow-up (p = 0.001), and 274 ± 100 μm at last visit (p < 0.001). 9 eyes (47%) achieved resolution of fluid at both initial and final follow-up visits.

While many eyes with nARMD respond favorably to initial anti-VEGF therapies, there is a significant subset of eyes that show persistent signs of disease activity with non-resolving macular edema despite several routine anti-VEGF treatments and thus may have worse visual outcomes. For this subset of patients, switching anti-VEGF agents is often a consideration. Authors hypothesized that faricimab may benefit eyes with previous incomplete response or non-response to two or more traditional anti-VEGF agents due to the novel mechanistic nature of the antibody. The results of the present study suggest that faricimab may result in anatomic improvement in this subset of patients without evidence of an associated functional benefit in terms of improvement in BCVA. CST, which started at an average of 310 ± 92 μm, decreased to 279 ± 88 μm by the initial follow-up visit, with minimal subsequent decrease to a final average of 274 ± 100 μm at last follow-up. Additionally, 9 eyes (47%) showed resolution of fluid at both initial follow-up and final follow-up visits.

In a subset of eyes with nARMD that showed persistent intraretinal and/or subretinal fluid refractory to treatment with traditional anti-VEGF agents, faricimab resulted in anatomic improvement in terms of mildly decreased CST and resolution of fluid in several eyes. However, there was no significant associated change in BCVA.
