Purpose: To evaluate the short-term effects of intravitreal faricimab (IVF) in treatment-resistant neovascular age-related macular degeneration (nAMD) subjects previously treated with intravitreal aflibercept (IVA). Methods: A retrospective review was conducted on nAMD patients undergoing IVA therapy at a single private practice institution. Subjects were divided into Study and Control groups. Both Study and Control subjects had undergone ≥6 IVA treatments during the previous 12 months, ≥4 IVA treatments during the previous 6 months, had a central macular thickness (CMT) on optical coherence tomography (OCT) of ≥300 microns, and had observable intraretinal and/or subretinal fluid on OCT prior to group assignment. Study subjects were switched from IVA to IVF and received 3 treatments within 4 months. Control subjects remained on IVA during the same time period and received 3 treatments within 4 months. Results: There were a total of 55 subjects analyzed. There were 39.3% (11/28) in the Study Group and 7.4% (2/27) in the Control Group attaining a CMT of less than 300 microns without retinal fluid on OCT at the end of the 4-month study period (p = 0.004). There were 35.7% (10/28) in the Study Group and 7.4% (2/27) in the Control Group gaining 2 or more lines of visual acuity at the end of the 4-month study period (p = 0.008). Conclusion: IVF can improve the visual and anatomic outcomes in a significant minority of treatment-resistant nAMD subjects previously managed with IVA. A greater follow-up period is needed to determine if such improvements can be maintained.
