The Central and Unacknowledged Role of the U.S. Food and Drug Administration in the Design and Execution of Medical Device Pivotal Trials

Abstract

The introduction of new medical devices has transformed cardiovascular care in recent decades. Devices, such as heart valves, pacemakers, stents, ventricular assist devices, and implantable defibrillators, have prolonged and improved the quality of life for millions of patients worldwide. Medical device innovation requires a robust ecosystem that involves medical technology innovators, often at start-ups, large medical device manufacturers, and clinical investigators. Central to this process is strong regulatory oversight, which in the United States is provided by the U.S. Food and Drug Administration’s Center for Devices and Radiologic Health (FDA/CDRH). This viewpoint discusses the effect of the regulatory approval process and the role that FDA/CDRH plays in the design and execution of the pivotal trials (clinical studies) that are used to support the regulatory approval of high-risk devices. We also review norms in the publication of pivotal trials in peer-reviewed medical journals; these publications often fail to acknowledge the role of the FDA/CRH or discuss results within the context of the device approval process.

In 2019, the co-founders of the Swedish medical start-up 1928 Diagnostics, CEO Dr. Kristina Lagerstedt and COO Dr. Susanne Staaf, had to pick the right business model to commercialize their novel technology to hospitals and health care providers. Developed in partnership with research hospitals to help fight the global antibiotic resistance crisis, the firm’s cloud-based technology platform helped partners identify resistant genes and mutations in bacteria more quickly and accurately, allowing for easier outbreak cluster tracking in support of hospital infection control management, as well as better diagnostics and antibiotic selection. By 2019, they had raised $5 million, employed 16 people, and had their tool deployed at 24 partner sites in 10 different countries. Their decisions on which markets to focus on and with which business model would crucially impact the young firm’s chances at successfully converting existing users and attracting new clients.

Emerging gene therapy and gene-editing technologies will have a growing impact on patient lives and health-care delivery. We analyzed a decade of data on clinical trials and venture capital investments to understand the likely trajectory of genetically focused therapies in the years ahead. The number of clinical trials and venture capital deals increased substantially from 2006–2017. We observed particularly notable growth in both industry-sponsored trials and trials involving specialty fields of drug development, including oncology, neurology, hematology, ophthalmology, and neurology. As the number of gene-therapy and gene-editing technologies continues to grow, we expect that such therapies will have a significant and heterogeneous impact on health-care delivery, including a shifting of resources from chronic disease management to more intense acute episodic care, an increase in the complexity of required intellectual property and manufacturing know-how, and the potential expansion of biopharmaceutical companies into service-based business models.

Assessing the Food and Drug Administration's Risk-Based Framework for Software Precertification with Top Health Apps in the United States: Quality Improvement Study

Noy Alon, Ariel Dora Stern and John Torous

BACKGROUND: As the development of mobile health apps continues to accelerate, the need to implement a framework that can standardize categorizing these apps to allow for efficient, yet robust regulation grows. However, regulators and researchers are faced with numerous challenges as apps have a wide variety of features, constant updates, and fluid use cases for consumers. As past regulatory efforts have failed to match the rapid innovation of these apps, the United States Food and Drug Administration (FDA) has proposed that the Software Precertification (Pre-Cert) Program and new risk-based framework could be the solution. OBJECTIVE: The objective of this study was to determine if the risk-based framework proposed by the FDA's Pre-Cert Program could standardize categorizing top U.S. health apps. METHODS: In this quality improvement study during the summer 2019, the top 10 apps for six disease conditions (addiction, anxiety, depression, diabetes, high blood pressure, and schizophrenia) in the United States Apple iTunes and Android Google Play Store were classified using the FDA's risk-based framework. Data on the presence of well-defined apps features, user engagement methods, popularity metrics, medical claims, and scientific backing were collected. RESULTS: The FDA's risk-based framework classifies an app's risk by the disease condition it targets and what information that app provides. Out of the 120 apps tested, 95 apps were categorized as targeting a non-serious health condition, while only seven targeted a serious condition and 18 apps targeted a critical condition. Since the majority of apps targeted a non-serious condition, their risk categorization was largely determined by what information they provided. The apps that were assessed as not requiring FDA review were more likely than those assessed as requiring review to be associated with the integration of external devices (15/58, 26% vs. 5/62, 8%; P=.03) and health information collection (24/58, 41% vs. 9/62, 15%; P =.008). Apps exempt from review were less likely to offer health information (25/58, 43% vs 45/62, 72%; P <.001), to connect users with professional care (7/58, 12% vs 14/62, 23%; P =.04), and to include an intervention (8/58, 14% vs. 35/62, 55%; P <.001). CONCLUSIONS: The FDA's risk-based framework has the potential to improve the efficiency of the regulatory review process for health apps. However, we were unable to identify a standard measure that differentiated apps requiring regulatory review from those that would not. Apps exempt from review also carried concerns regarding privacy and data security. Before the framework is used to assess the need for formal review of digital health tools, further research and regulatory guidance are needed in order to ensure that the Pre-Cert Program operates in the greatest interest of the public health.
