Introduction: Anti-vascular endothelial growth factor (anti-VEGF) drugs are widely used for the treatment of several cancers and retinal diseases. The systemic use of anti-VEGF drugs has been associated with an increased risk of serious adverse reactions. Whether this risk is also related to intravitreal administration of anti-VEGF drugs is unclear. Objective: The aim of this study was to provide an overview of the safety of anti-VEGF drugs in oncology and ophthalmology settings using the Italian Spontaneous Reporting System (SRS). Methods: We selected all suspected adverse drug reaction (ADR) reports attributed to anti-VEGF drugs and conducted descriptive frequency analyses stratified by indication of use. As a measure of disproportionality, we calculated the proportional reporting ratio with 95% confidence intervals at the level of standardized Medical Dictionary for Regulatory Activities (MedDRA®) queries (SMQs). Results: Of a total of 2472 anti-VEGF drug-related reports, 2173 (87.9%) and 299 (12.1%) were attributed to systemic and intravitreal use of these drugs, respectively. The frequency of serious ADRs reported was higher for intravitreal administration of anti-VEGF drugs than for systemic use in patients with cancer (58.9 vs. 34.1%) (p < 0.001) and were disproportionally associated with ischemic heart disease and thromboembolic and cerebrovascular events. Most serious ADRs related to anti-VEGF drugs in patients with cancer are known and clinically relevant (e.g., gastrointestinal and vascular disorders). Conclusions: This study documented that serious ADRs and systemic toxicity may occur not only with systemic use of anti-VEGF drugs in patients with cancer but also with intravitreal administration. Close monitoring of cardio/cerebrovascular adverse events should be considered during treatment with all anti-VEGF drugs

Abstract

Introduction: Anti-vascular endothelial growth factor (anti-VEGF) drugs are widely used for the treatment of several cancers and retinal diseases. The systemic use of anti-VEGF drugs has been associated with an increased risk of serious adverse reactions. Whether this risk is also related to intravitreal administration of anti-VEGF drugs is unclear. Objective: The aim of this study was to provide an overview of the safety of anti-VEGF drugs in oncology and ophthalmology settings using the Italian Spontaneous Reporting System (SRS). Methods: We selected all suspected adverse drug reaction (ADR) reports attributed to anti-VEGF drugs and conducted descriptive frequency analyses stratified by indication of use. As a measure of disproportionality, we calculated the proportional reporting ratio with 95% confidence intervals at the level of standardized Medical Dictionary for Regulatory Activities (MedDRA®) queries (SMQs). Results: Of a total of 2472 anti-VEGF drug-related reports, 2173 (87.9%) and 299 (12.1%) were attributed to systemic and intravitreal use of these drugs, respectively. The frequency of serious ADRs reported was higher for intravitreal administration of anti-VEGF drugs than for systemic use in patients with cancer (58.9 vs. 34.1%) (p < 0.001) and were disproportionally associated with ischemic heart disease and thromboembolic and cerebrovascular events. Most serious ADRs related to anti-VEGF drugs in patients with cancer are known and clinically relevant (e.g., gastrointestinal and vascular disorders). Conclusions: This study documented that serious ADRs and systemic toxicity may occur not only with systemic use of anti-VEGF drugs in patients with cancer but also with intravitreal administration. Close monitoring of cardio/cerebrovascular adverse events should be considered during treatment with all anti-VEGF drugs
