Though vascular endothelial growth factors (VEGF) and other proangiogenic factors, such as angiopoietins (Ang), may be involved in the development of neovascular age-related macular degeneration (nvAMD), only drugs that inhibit the VEGF family are available for the treatment. The newly approved anti-VEGF drug faricimab, which also inhibits Ang-2, is expected to be effective in patients with AMD refractory to conventional anti-VEGF drugs. Therefore, we prospectively investigated the efficacy of faricimab in the treatment of aflibercept-refractory nvAMD. Patients with nvAMD who had been treated with aflibercept in the last year and required bimonthly injections were recruited. 25 eyes showed persistent exudative changes immediately before the faricimab injection (baseline). In these 25 eyes, switching to faricimab did not change visual acuity or central retinal thickness 2 months after the injection; however, 56% of eyes showed reduction or complete absorption of fluid. Notably, 25% of the eyes that showed dry macula at month 2 had no fluid recurrence for up to 4 months. These results indicate that faricimab could benefit some patients with aflibercept-refractory nvAMD.
虽然血管内皮生长因子(VEGF)和其他促血管生成因子,如血管生成素(Ang),可能参与新生血管性年龄相关性黄斑变性(nvAMD)的发生,但目前仅可使用抑制 VEGF 家族的药物进行治疗。新批准的抗 VEGF 药物 faricimab 也可抑制 Ang-2,有望对常规抗 VEGF 药物治疗抵抗的 AMD 患者有效。因此,我们前瞻性地研究了 faricimab 治疗 aflibercept 抵抗的 nvAMD 的疗效。我们招募了在过去一年中接受 aflibercept 治疗且需要每两个月注射一次的 nvAMD 患者。25 只眼在接受 faricimab 注射前(基线)立即出现持续性渗出性改变。在这 25 只眼中,注射后 2 个月时,转换为 faricimab 并未改变视力或中心视网膜厚度;然而,56%的眼显示液体减少或完全吸收。值得注意的是,在第 2 个月时表现为干性黄斑的 25%的眼中,高达 4 个月内没有再次出现液体复发。这些结果表明,faricimab 可能使一些 aflibercept 抵抗的 nvAMD 患者受益。
