For instance, Medable and Science 37 are utilizing AI to conduct decentralized trials, increasing reach and patient engagement. AI also simplifies the identification of suitable patient subgroups based on clinical and genetic characteristics, promoting more personalized medicine approaches. Regulatory agencies like the FDA are becoming increasingly accepting of AI use in trial protocols, with initiatives such as the FDA's Digital Health Center of Excellence facilitating the appropriate use of AI within clinical trials. These advancements are all contributing to the widespread adoption of AI throughout the clinical trial market.
What is an AI in Clinical Trials?
AI in Clinical Trials refers to the application of artificial intelligence technologies, such as machine learning, natural language processing, and computer vision, to enhance and accelerate various aspects of the clinical trial process. AI enhances patient recruitment by selecting eligible patients from electronic health records, automating the design and writing of trials and protocols, forecasting patient dropout, and tracking the status of the trial in real time. It also enables data analysis, identification of adverse events, and ensures regulatory compliance. AI plays an important role in decentralized trials by enabling remote monitoring through wearable technologies and mobile applications. Besides improving efficiency in trials, these technological advancements reduce costs, shorten timelines, and enhance the accuracy and personalization of trial outcomes.
