Comprehensive Review of Ocular and Systemic Safety Events with Intravitreal Aflibercept Injection in Randomized Controlled Trials.

ABSTRACT

PURPOSE: To assess the ocular and systemic safety of intravitreal aflibercept injection (IAI) compared with controls in IAI trials in neovascular age-related macular degeneration (nAMD), macular edema following central retinal vein occlusion (MEfCRVO), macular edema following branch retinal vein occlusion (MEfBRVO), and diabetic macular edema (DME). DESIGN: Comprehensive review of 10 phase II and III trials of IAI in retinal diseases. PARTICIPANTS: Patients were included from IAI trials in nAMD (CLEAR-IT 2 [52 weeks], VIEW 1 [96 weeks], VIEW 2 [96 weeks], VIEW 1 extension [208 weeks]); MEfCRVO (COPERNICUS [100 weeks], GALILEO [76 weeks]); MEfBRVO (VIBRANT [52 weeks]); and DME (DA VINCI [52 weeks], VIVID [100 weeks], VISTA [100 weeks]). METHODS: Rates were calculated as events/100 person-years at risk (PYR). When applicable, rate ratios (RRs) and 95% confidence intervals (CIs) were provided. MAIN OUTCOME MEASURES: Outcomes included rates for intraocular inflammation, endophthalmitis, serious adverse events (SAEs), wound-healing complications, hypertension (HTN), adjudicated Anti-Platelet Trialists' Collaboration (APTC)-defined arterial thromboembolic events (ATEs) (nonfatal myocardial infarction, nonfatal stroke, and vascular death), and death from all causes. RESULTS: More than 4000 patients contributed >7000 PYR. For all outcomes, there were no meaningful differences between evaluated adverse event rates for IAI and controls. Overall intraocular inflammation rates were 2.37 (control) and 2.06 (IAI); overall RR was 0.87 (95% CI, 0.61-1.27). Overall endophthalmitis rates were 0.52 (control) and 0.22 (IAI); overall RR was 0.42 (95% CI, 0.18-1.03). Overall SAE rates were 23.09 (control) and 20.80 (IAI); overall RR was 0.90 (95% CI, 0.80-1.02). Overall rates of wound-healing complications were 0.17 (control) and 0.15 (IAI); overall RR was 0.85 (95% CI, 0.24-3.86). Overall HTN rates were 14.87 (control) and 11.27 (IAI), with an overall RR of 0.76 (95% CI, 0.65-0.89); HTN rates were highest in MEfBRVO and lowest in nAMD. For adjudicated APTC-defined ATEs, rates were 2.04 (control) and 2.19 (IAI), with an RR of 1.07 (95% CI, 0.73-1.61). Overall death rates were 1.16 (control) and 1.49 (IAI); overall RR was 1.28 (95% CI, 0.80-2.15). CONCLUSIONS: Rates of selected ocular and systemic adverse events with IAI were similar to those of controls and similar across disease states in evaluated IAI trials. Intravitreal aflibercept injection was generally well tolerated in the patients evaluated.
