The purpose of this study was to compare intravitreal nesvacumab (anti-angiopoietin 2) plus aflibercept with intravitreal aflibercept injection (IAI) in diabetic macular edema.
The eyes (n = 302) were randomized (1:2:3) to nesvacumab 3 mg + aflibercept 2 mg (LD combo), nesvacumab 6 mg + aflibercept 2 mg (HD combo), or IAI 2 mg at baseline, Weeks 4 and 8. LD combo continued every 8 weeks (q8w). HD combo was rerandomized at Week 12 to q8w or every 12 weeks (q12w); IAI to q8w, q12w, or HD combo q8w through Week 32.
Week 12 best-corrected visual acuity gains for LD and HD combo versus IAI were 6.8, 8.5, and 8.8 letters; Week 36 changes were similar. Central subfield retinal thickness reductions at Week 12 were -169.4, -184.0, and -174.6 µm (nominal P = 0.0183, HD combo vs. IAI); Week 36 reductions for LD combo and HD combo q8w and q12w versus IAI were -210.4, -223.4, and -193.7 versus -61.9 µm (nominal P < 0.05). At Week 12, 13.3% and 21.3% versus 15.2% had ≥2-step Diabetic Retinopathy Severity Scale improvement (LD and HD combos vs. IAI) and 59.6% and 66.3% versus 53.7% had complete foveal center fluid resolution. Safety was comparable across groups.
Nesvacumab + aflibercept demonstrated no additional visual benefit over IAI. Anatomic improvements with HD combo may warrant further investigation.
本研究旨在比较玻璃体内注射奈维单抗(抗血管生成素 2)联合阿柏西普与玻璃体内注射阿柏西普(IAI)治疗糖尿病性黄斑水肿的疗效。
本研究纳入 302 只眼,按 1:2:3 的比例随机分配至奈维单抗 3mg+阿柏西普 2mg(LD 联合治疗组)、奈维单抗 6mg+阿柏西普 2mg(HD 联合治疗组)或 IAI 2mg 治疗组,在基线、第 4 周和第 8 周时给药。LD 联合治疗组每 8 周(q8w)给药 1 次。HD 联合治疗组在第 12 周时重新随机分为 q8w 或每 12 周(q12w)1 次;IAI 组则每 8 周、每 12 周或 HD 联合治疗组 q8w 治疗至第 32 周。
治疗第 12 周时,与 IAI 相比,LD 和 HD 联合治疗组的最佳矫正视力(BCVA)增益分别为 6.8、8.5 和 8.8 个字母;治疗第 36 周时,这种变化趋势仍然相似。治疗第 12 周时,中央视网膜厚度(CRT)较基线的减少值分别为-169.4μm、-184.0μm 和-174.6μm(名义 P=0.0183,HD 联合治疗组 vs. IAI 组);治疗第 36 周时,LD 联合治疗组和 HD 联合治疗组 q8w 和 q12w 与 IAI 相比,CRT 减少值分别为-210.4μm、-223.4μm 和-193.7μm,而 IAI 组的 CRT 减少值为-61.9μm(名义 P<0.05)。治疗第 12 周时,LD 和 HD 联合治疗组分别有 13.3%和 21.3%的患者(vs. IAI 组,15.2%)的糖尿病视网膜病变严重程度评分(DRS)改善≥2 个等级,59.6%和 66.3%的患者(vs. IAI 组,53.7%)的黄斑中心凹完全无液。各组间的安全性无差异。
与 IAI 相比,奈维单抗+阿柏西普并未带来额外的视力获益。HD 联合治疗的解剖学改善可能需要进一步研究。
