Real-World-Data of Treatment-Naïve and Previously Treated Patients Receiving Up to 3 Injections of Faricimab in Neovascular Age-Related Macular Degeneration.

PURPOSE

To evaluate visual and anatomical outcome of consecutive patients who received intravitreal injections (IVI) of faricimab for the treatment of neovascular age-related macular degeneration (nAMD).

PATIENTS AND METHODS

A retrospective study of patients treated for nAMD with one to three IVIs of faricimab from October 2022 to January 2024. Demographic data, treatment history, best corrected visual acuity (BCVA), anatomic parameters, and adverse events (AEs) were collected.

RESULTS

After one IVI of faricimab, previously treated (n=160) eyes with a mean of 33.51 IVIs and treatment-naïve (n=10) eyes showed a mean BCVA gain of +0.59±0.52 letters (p=0.364) and +5.00±6.50 letters (p=0.461), respectively, and a mean central subfield thickness (CST) reduction of -27.65±5.33 µm (p<0.001) and -94.10±39.74 μm (p=0.042), respectively. In treatment-refractory eyes after switching from aflibercept (n=108), mean BCVA increased by +0.42±0.66 (p=0.745) and the mean CST improved by -21.98±6.04 (p<0.001). After three IVIs of faricimab previously treated (n=106) and treatment-naïve (n=5) eyes showed a mean BCVA increase of +1.57±0.88 letters (p=0.051) versus +12.50±8.14 letters (p=0.185), and a mean CST reduction of -25.51±5.82 µm (p<0.001) versus -82.60±36.20 µm from baseline, respectively. In treatment-refractory eyes after switching from aflibercept (n=79), mean BCVA improved by +2.15±1.08 letters (p=0.029) and mean CST decreased by -27.46±7.04 µm (p<0.001). Mean pigment epithelial detachment (PED) was also significantly reduced even between the first and the third faricimab injection in previously treated eyes (p=0.03). The proportion of eyes with intraretinal fluid and subretinal fluid improved significantly in all eyes and treatment-refractory eyes after switching from aflibercept. Ocular AEs were reported in three out of 170 eyes, and one patient had two stroke events during faricimab therapy.

CONCLUSION

Three IVIs of faricimab have the potential to improve visual acuity and anatomical parameters even in treatment-refractory nAMD eyes with a mean dosing interval of more than 6 weeks.
