RESUMO
INTRODUCTION: On 4 February, 2020, the Secretary of the Department of Health and Human Services declared a public health emergency related to coronavirus disease 2019 (COVID-19), and on 27 March, 2020 declared circumstances existed to justify the authorization of the emergency use of drug and biological products (hereafter, "drugs") for COVID-19. At the outset of the pandemic with uncertainty relating to the virus, many drugs were being used to treat or prevent COVID-19, resulting in the US Food and Drug Administration's (FDA's) need to initiate heightened surveillance across these drugs. OBJECTIVE: We aimed to describe the FDA's approach to monitoring the safety of drugs to treat or prevent COVID-19 across multiple data sources and the subsequent actions taken by the FDA to protect public health. METHODS: The FDA conducted surveillance of adverse event and medication error data using the FDA Adverse Event Reporting System, biomedical literature, FDA-American College of Medical Toxicology COVID-19 Toxicology Investigators Consortium Pharmacovigilance Project Sub-registry, and the American Association of Poison Control Centers National Poison Data System. RESULTS: From 4 February, 2020, through 31 January, 2022, we identified 22,944 unique adverse event cases worldwide and 1052 unique medication error cases domestically with drugs to treat or prevent COVID-19. These were from the FDA Adverse Event Reporting System (22,219), biomedical literature (1107), FDA-American College of Medical Toxicology COVID-19 Toxicology Investigator's Consortium Sub-registry (638), and the National Poison Data System (32), resulting in the detection of several important safety issues. CONCLUSIONS: Safety surveillance using near real-time data was critical during the COVID-19 pandemic because the FDA monitored an unprecedented number of drugs to treat or prevent COVID-19. Additionally, the pandemic prompted the FDA to accelerate innovation, forging new collaborations and leveraging data sources to conduct safety surveillance to respond to the pandemic.

Complex regulatory and scientific considerations exist for drug-device combination products submitted under an Abbreviated New Drug Application. The Agency has published several guidances to aid industry in the development of a generic drug-device combination product: providing recommendations on the types of studies necessary to establish bioequivalence, providing considerations on product quality and performance for certain types of device constituents, and most recently, providing tools to assess the proposed user interface when compared to the user interface of the Reference Listed Drug. In addition, the Office of Generic Drugs1 has established a regulatory science research program intended to support projects that examine scientific questions relating to the development of generic combination products and their associated regulatory review. Several research examples are described within this article, which demonstrate how equivalence can be evaluated when the function of the device could potentially impact drug delivery. Moreover, this article provides an overview of regulatory recommendations and ongoing scientific research efforts to further develop guidances and ultimately improve public access to generic combination products.
