ABSTRACT
PURPOSE:
To investigate differences in the development of macular atrophy (MA) over 24 months between treat-and-extend (T&E) ranibizumab and aflibercept in patients with neovascular age-related macular degeneration (nAMD).DESIGN:
A phase 4 randomized, partially masked, multicenter study.PARTICIPANTS:
Individuals 50 years of age or older diagnosed with active, treatment-naïve subfoveal choroidal neovascularization secondary to nAMD with baseline best-corrected visual acuity (BCVA) of 23 logarithm of minimum angle of resolution letters or more.METHODS:
Patients were randomized 11 to receive either intravitreal injections of ranibizumab 0.5 mg or aflibercept 2.0 mg and were treated according to the same reading center-guided T&E regimen after 3 initial monthly injections. MAIN OUTCOMEMEASURES:
The primary outcome was mean change in square root area of MA from baseline to month 24. Key secondary outcomes included number of injections and mean change in BCVA from baseline to months 12 and 24.RESULTS:
Two hundred seventy-eight patients were included in the analysis (ranibizumab 0.5 mg, n = 141; aflibercept 2.0 mg, n = 137). Mean change in square root area of MA from baseline to month 24 was +0.36 mm (95% confidence interval [CI], 0.27-0.45 mm) for ranibizumab and +0.28 mm (95% CI, 0.19-0.37 mm) for aflibercept (treatment difference, +0.08 mm [95% CI, -0.05 to 0.21 mm]; P = 0.24). The proportion of patients with MA increased from 7% (10/141) to 37% (43/117) for ranibizumab and from 6% (8/137) to 32% (35/108) for aflibercept from baseline to month 24. The average number of injections received per year was similar between both groups 9.6 (95% CI, 9.2-10.0) for ranibizumab and 9.5 (95% CI, 9.1-9.9) for aflibercept. The mean change in BCVA from baseline to month 24 was +6.6 letters (95% CI,4.7-8.5 letters) for the ranibizumab group and +4.6 letters (95% CI, 2.7-6.6 letters) for the aflibercept group ( P = 0.15). Rates of adverse events (AEs) were similar between both groups.CONCLUSIONS:
No significant differences in the rate of development or growth of MA over 24 months were observed between ranibizumab and aflibercept in nAMD patients treated using an identical T&E regimen.
