FDA Publishes Digital Health and Artificial Intelligence Glossary

On December 18, 2025, the Food and Drug Administration (FDA) released a final guidance entitled “Processes and Practices Applicable to Bioresearch Monitoring Inspections.” The guidance was issued to comply with the Food and Drug Omnibus Reform Act of 2022, which directs FDA to issue guidance describing the processes and practices applicable to inspections of sites and facilities inspected under FDA’s Bioresearch Monitoring (BIMO) inspection program, to the extent that is not covered in already available FDA guides and manuals. The BIMO program was established to assess and monitor the conduct and reporting of FDA-regulated research as well as postmarketing activities through on-site inspections, investigations and Remote Regulatory Assessments.

On December 5, 2025, FDA announced its Technology-Enabled Meaningful Patient Outcomes (TEMPO) for Digital Health Devices Pilot, a new voluntary pilot that seeks to accelerate innovation and expand access to digital health devices for people living with chronic conditions. Under TEMPO, FDA will evaluate a new, risk-based enforcement approach that supports digital health devices intended for use to improve patient outcomes in cardio-kidney-metabolic, musculoskeletal and behavioral health conditions. Under the pilot, participating manufacturers may request that the agency exercise enforcement discretion for certain requirements, such as premarket authorization and investigational device requirements, while manufacturers collect and share real-world data demonstrating the device’s performance.

Last week, FDA released draft guidance titled “Scientific Considerations in Demonstrating Biosimilarity to a Reference Product: Updated Recommendations for Assessing the Need for Comparative Efficacy Studies.” This draft guidance reflects an evolution in FDA’s approach to determining whether a comparative clinical study with efficacy endpoints (a comparative efficacy study or CES) is necessary to support a demonstration of biosimilarity. Specifically, the agency notes that a comparative analytical assessment (CAA) is generally more sensitive when it comes to detecting differences between products than a CES.

On October 23, 2025, FDA released its final guidance regarding Patient-Focused Drug Development: Selecting, Developing, or Modifying Fit-for-Purpose Clinical Outcome Assessments. The guidance is the third guidance in a four-part series of FDA guidance focused on patient-focused drug development (PFDD) that describe how stakeholders, such as patients, caregivers, researchers, medical product developers and others can submit patient experience data and other relevant information that can be used for medical product development and regulatory decision making.
