Empowering drug development: Leveraging insights from imaging technologies to enable the advancement of digital health technologies

Abstract

The US Food and Drug Administration (FDA) has publicly recognized the importance of improving drug development efficiency, deeming translational biomarkers a top priority. The use of imaging biomarkers has been associated with increased rates of drug approvals. An appropriate level of validation provides a pragmatic way to choose and implement these biomarkers. Standardizing imaging modality selection, data acquisition protocols, and image analysis (in ways that are agnostic to equipment and algorithms) have been key to imaging biomarker deployment. The best known examples come from studies done via precompetitive collaboration efforts, which enable input from multiple stakeholders and data sharing. Digital health technologies (DHTs) provide an opportunity to measure meaningful aspects of patient health, including patient function, for extended periods of time outside of the hospital walls, with objective, sensor‐based measures. We identified the areas where learnings from the imaging biomarker field can accelerate the adoption and widespread use of DHTs to develop novel treatments. As with imaging, technical validation parameters and performance acceptance thresholds need to be established. Approaches amenable to multiple hardware options and data processing algorithms can be enabled by sharing DHT data and by cross‐validating algorithms. Data standardization and creation of shared databases will be vital. Pre‐competitive consortia (public‐private partnerships and professional societies that bring together all stakeholders, including patient organizations, industry, academic experts, and regulators) will advance the regulatory maturity of DHTs in clinical trials.

In vivo medical imaging for assessing geroprotective interventions in humans

“…The use of in vivo imaging techniques to aid drug development is not new. For decades, pharmaceutical companies have successfully included imaging as part of their development pipelines 117 . However, instead of focusing on a single tissue or indication, which is the usual practice in drug development, we propose to study multiple pathological processes in parallel.…”

Empowering rheumatology through digital health technologies: contributions and barriers

“…Digital health systems streamline patient records, making them easily accessible to all healthcare providers and facilities. This promotes care coordination, reduces duplication of tests, and improves the continuity of care for RMD patients [22]. Moreover, EHRs can also be a tool for clinical decision-making [5].…”

A proposed multi‐domain, digital model for capturing functional status and health‐related quality of life in oncology

“…Importantly, we present a device‐agnostic model to allow for flexibility depending on study hypotheses, characteristics of the study sample, and different data collection environments. Moreover, an agnostic approach to technology selection has been demonstrated to be critical for broader technology adoption in multi‐center studies, 62 contingent on the demonstration of data comparability across different tools. When determining which combination of DHTs may be useful for capturing outcomes aligned to our proposed model, several considerations must be addressed.…”
