PURPOSE To test the hypothesis that tolerating some subretinal fluid (SRF) in patients with neovascular age-related macular degeneration (nAMD) treated with ranibizumab using a treat-and-extend (T&E) regimen can achieve similar visual acuity (VA) outcomes as treatment aimed at resolving all SRF. DESIGN Multicenter, randomized, 24-month, phase 4, single-masked, noninferiority clinical trial. PARTICIPANTS Participants with treatment-naïve active subfoveal choroidal neovascularization (CNV). METHODS Participants were randomized to receive ranibizumab 0.5 mg monthly until either complete resolution of SRF and intraretinal fluid (IRF; intensive arm: SRF intolerant) or resolution of all IRF only (relaxed arm: SRF tolerant except for SRF >200 μm at the foveal center) before extending treatment intervals. A 5-letter noninferiority margin was applied to the primary outcome. MAIN OUTCOME MEASURES Mean change in best-corrected VA (BCVA), and central subfield thickness and number of injections from baseline to month 24. RESULTS Of the 349 participants randomized (intensive arm, n = 174; relaxed arm, n = 175), 279 (79.9%) completed the month 24. The mean change in BCVA from baseline to month 24 was 3.0 letters (standard deviation, 16.3 letters) in the intensive group and 2.6 letters (standard deviation, 16.3 letters) in the relaxed group, demonstrating noninferiority of the relaxed compared with the intensive treatment (P = 0.99). Similar proportions of both groups achieved 20/40 or better VA (53.5% and 56.6%, respectively; P = 0.92) and 20/200 or worse VA (8.7% and 8.1%, respectively; P = 0.52). Participants in the relaxed group received fewer ranibizumab injections over 24 months (mean, 15.8 [standard deviation, 5.9]) than those in the intensive group (mean, 17 [standard deviation, 6.5]; P = 0.001). Significantly more participants in the intensive group never extended beyond 4-week treatment intervals (13.5%) than in the relaxed group (2.8%; P = 0.003), and significantly more participants in the relaxed group extended to and maintained 12-week treatment intervals (29.6%) than the intensive group (15.0%; P = 0.005). CONCLUSIONS Patients treated with a ranibizumab T&E protocol who tolerated some SRF achieved VA that is comparable, with fewer injections, with that achieved when treatment aimed to resolve all SRF completely.

雷尼单抗治疗和扩展方案治疗新血管性年龄相关性黄斑变性中的视网膜下液耐受:FLUID研究24个月结果。

目的测试以下假设:在接受兰尼单抗治疗和治疗(T&E)方案治疗的新生血管性年龄相关性黄斑变性(nAMD)患者中,可以耐受某些视网膜下液(SRF)可以达到与治疗相似的视力(VA)结果旨在解决所有SRF。设计多中心,随机,24个月,第4期,单掩盖,非劣效性临床试验。研究对象:未接受过治疗的活动性中央凹下脉络膜新血管形成(CNV)的参与者。方法将参与者随机接受每月0.5 mg雷珠单抗的治疗,直至SRF和视网膜内液完全消退(IRF;强直臂:对SRF耐受)或仅对所有IRF消退(放松臂:对SRF耐受),但中心凹处SRF> 200μm除外),然后再延长治疗间隔。对主要结局采用5个字母的自卑边际。主要观察指标:从基线到第24个月,最佳校正后的VA(BCVA),中心子场厚度和注射次数的平均变化。结果在349名参与者中进行了随机分组(强化组,n = 174;放松组,n = 175), 279(79.9%)人在24月内完成。从基线到24月,BCVA的平均变化在强化组中为3.0个字母(标准差,16.3个字母),在放松组中为2.6个字母(标准差,16.3个字母),表明与强化治疗相比,放松的非劣效性(P = 0.99)。两组的相似比例达到20/40或更高的VA(分别为53.5%和56.6%; P = 0.92)和20/200或更低的VA(分别为8.7%和8.1%; P = 0.52)。放松组的参与者在24个月内接受雷珠单抗注射的次数较少(均值15.8 [标准差,5.9]),而强化组的参与者(平均数17,[标准差,6.5]; P = 0.001)。在强化治疗组中,从未超过4周治疗间隔的参与者(13.5%)比在放松组中(2.8%; P = 0.003)更多,并且在放松治疗组中,延长并维持12周治疗间隔的参与者明显更多(29.6%)比强化组(15.0%; P = 0.005)。结论接受兰尼单抗T&E方案治疗的患者能够耐受某些SRF,其VA值可与注射量较少的患者相媲美,而其治疗目的是完全解决所有SRF。17 [标准偏差,6.5];P = 0.001)。在强化治疗组中,从未超过4周治疗间隔的参与者(13.5%)比在放松组中(2.8%; P = 0.003)更多,并且在放松治疗组中,延长并维持12周治疗间隔的参与者明显更多(29.6%)比强化组(15.0%; P = 0.005)。结论接受兰尼单抗T&E方案治疗的患者能够耐受某些SRF,其VA值可与注射量较少的患者相媲美,而其治疗目的是完全解决所有SRF。17 [标准偏差,6.5];P = 0.001)。在强化治疗组中,从未超过4周治疗间隔的参与者(13.5%)比在放松组中(2.8%; P = 0.003)更多,并且在放松治疗组中,延长并维持12周治疗间隔的参与者明显更多(29.6%)比强化组(15.0%; P = 0.005)。结论接受兰尼单抗T&E方案治疗的患者能够耐受某些SRF,其VA值可与注射量较少的患者相媲美,而其治疗目的是完全解决所有SRF。与放松组相比,放松组的参与者延长至并维持12周治疗间隔(29.6%)的比例明显高于加强组(15.0%; P = 0.005)。结论接受兰尼单抗T&E方案治疗的患者能够耐受某些SRF,其VA值可与注射量较少的患者相媲美,而其治疗目的是完全解决所有SRF。与放松组相比,放松组的参与者延长至并维持12周治疗间隔(29.6%)的比例明显高于加强组(15.0%; P = 0.005)。结论接受兰尼单抗T&E方案治疗的患者能够耐受某些SRF,其VA值可与注射量较少的患者相媲美,而其治疗目的是完全解决所有SRF。
