Abstract

Background/aims: To evaluate the efficacy, safety and durability of intravitreal faricimab in patients with neovascular age-related macular degeneration (nAMD) with unsatisfactory response to traditional anti-vascular endothelial growth factor (anti-VEGF) agents.

Methods: Single-centre, prospective cohort study of all consecutive patients with nAMD who were switched to intravitreal faricimab from intravitreal ranibizumab or aflibercept, due to unsatisfactory treatment response (maximal fluid-free interval ≤ 8 weeks). Intravitreal faricimab was administered with a loading dose of four 4-weekly injections, followed by an 8-week extension. A treat and extend (T&E) regime was adopted thereafter. Primary outcome was the difference between the maximal fluid-free interval achieved with faricimab, and the one achieved before the switch. Morpho-functional outcomes were also assessed. Secondary outcome was accordance with clinical management when applying faricimab pivotal trial criteria versus our real-world T&E protocol, measured as a proportion.

Results: Twenty-six eyes of 26 patients with a median age of 82 years (range 77-85) were included. Patients were followed for 30.2 weeks (range 26.3-33.1). Maximal fluid-free interval after switch to faricimab (Mdn = 6.0 weeks; IQR = 4-8) was longer than the maximum interval before the switch (Mdn = 4.0 weeks; IQR = 4-4), p < 0.001. Comparing real-world T&E protocol with pivotal trial criteria, 8 (30.8%) eyes received the same clinical management while 18 (69.2%) eyes were kept at a shorter interval when following our T&E protocol. No serious adverse events were recorded.

Conclusions: Faricimab appears to increase the fluid-free interval and allow extension of dosing interval in patients with nAMD poorly responsive to traditional anti-VEGF drugs.
