One-year clinical outcomes of four-dose induction versus immediate treat-and-extend faricimab regimens in pretreated neovascular age-related macular degeneration
摘要
This study aimed to compare one-year clinical outcomes of two faricimab treatment strategies in patients with previously treated exudative neovascular age-related macular degeneration (nAMD): (1) immediate switch to treat-and-extend dosing (T&E), and (2) initiation with a four-dose induction (“loading”) regimen.
Subject/methodsRetrospective comparing two cohorts of pretreated nAMD patients with 12 months of follow-up who were either switched to Faricimab with immediate T&E dosing (Lucerne protocol, “on-the-fly”), or initiated with a four-dose induction phase (Lugano protocol,“re-loading”). Both cohorts were subsequently managed according to a T&E regimen. Demographic and clinical data, including prior intravitreal agents, best-corrected visual acuity (BCVA), central subfield thickness (CST) on optical coherence tomography (OCT), and length of treatment intervals were analysed. Multivariable models were adjusted for baseline differences.
ResultsBoth cohorts (Lucerne, 183 eyes; Lugano, 33 eyes) were similar in baseline characteristics. BCVA improved by 0.81 ETDRS letters in Lucerne and by 2.42 in the Lugano cohort (p = 0.250). CRT decreased by -38.3 μm in Lucerne and by -57.8 μm in Lugano (p = 0.053). Treatment intervals increased by 2.2 weeks in Lucerne and 3.4 weeks in Lugano (p = 0.092). At 12 months, 15.3% of Lucerne patients and 27.3% of Lugano patients achieved intervals ≥ 12 weeks, with significantly higher odds of extension in Lugano (OR 3.87; p = 0.013).
ConclusionsBoth cohorts showed anatomical and functional improvements after switching to faricimab. The Lugano cohort, using a four-dose induction phase, showed longer treatment intervals, suggesting better disease stability.
