Intravitreal Ziv-Aflibercept: Clinical Effects and Economic Impact

Abstract

During the past decade, drugs that inhibit the actions of vascular endothelial growth factor (VEGF) have become standard-of-care treatment for a variety of chorioretinal vascular conditions. The off-label, intravitreal use of ziv-aflibercept (Zaltrap) has provided clinicians with an additional cost-effective drug. The commercial preparation of ziv-aflibercept contains the same aflibercept (VEGF-trap) molecule as Eylea but has a much higher osmolarity (1000 mOsm/kg vs 300 mOsm/kg). Initial concerns regarding cytotoxicity and long-term safety of intravitreal ziv-aflibercept have been largely negated after a series of publications failed to identify adverse ocular and systemic side effects. Both treatment-naive and anti-VEGF‒resistant cases of neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), retinal vein occlusion (RVO), and choroidal neovascular membrane (CNVM) may respond as well to ziv-aflibercept as to aflibercept. A higher dose of ziv-aflibercept (2 mg in 0.08 mL) does not cause any adverse effects during short-term follow-up period (1 month). Data from various sources suggest that ziv-aflibercept may be as cost effective as bevacizumab, thereby making it an attractive treatment option in low- and middle-income countries. However, problems with off-label use, compounding, and counterfeiting limit its availability in many countries. Data from prospective, randomized, multicenter clinical trials are still required to convince physicians and regulatory bodies of its clinical efficacy and potential as early therapy.
