ABSTRACT Medication samples of anti-VEGF agents can represent a good option for retina specialists to provide timely treatment for newly converted neovascular age-related macular degeneration (nvAMD) while prior-authorizations (PA) are pending. Our study examines the effect of medication sample use (ranibizumab or aflibercept) on future anti-vascular endothelial growth factor (VEGF) agent selection in nvAMD.


Conclusions: Sample medications in nvAMD may be initiated for many reasons, including awaiting PA approval. Our study found that eyes receiving a sample anti-VEGF agent (ranibizumab or aflibercept) for their initial injection were less likely to receive bevacizumab at future visits relative to eyes that did not receive an anti-VEGF sample, even after one year of treatment. Given the persistent use of more expensive medications at subsequent injections for patients who were initiated on samples, insurance payors may consider waiving PA requirements for bevacizumab to avoid a paradoxical increase in health-care costs.
