Evaluation of a remote biomarker capture system integrated with REDCap: A decentralized randomized trial

Remote smartphone cognitive testing using the ALLFTD Mobile App was feasible and acceptable for people with frontotemporal dementia and at-risk kindreds, supporting decentralised trials and improved access to research.

A direct-to-participant, multichannel recruitment strategy enrolled 34,244 older adults into a virtual trial testing an Apple Watch based heart health programme with electrocardiogram and irregular rhythm notification features, achieving broad geographic and gender diversity but under-representing non-White ethnic groups.

Home spirometry gave slightly lower percent-predicted FEV1 values than office measurements cross-sectionally, but the three-month change in lung function did not differ significantly between settings. This suggests home spirometry can reliably detect treatment effects, supporting its use as an endpoint for decentralised cystic fibrosis trials.

Wearable-derived digital biomarkers have been accepted by regulatory agencies as endpoints in clinical trials for Duchenne muscular dystrophy, showing their potential to support decentralised diagnostics through patient-centric monitoring. This matters because it enables more sensitive and continuous assessment of disease progression outside clinical settings.

The study found that acoustic speech features differed significantly between Android and iOS devices, with iOS recordings showing more periodic content but less high-frequency energy, while Android devices exhibited greater measurement variability. These platform-specific differences, coupled with participant experience challenges such as iOS users struggling with background noise checks, demonstrate that device choice and app instruction design materially affect data quality and trial outcomes in decentralised digital biomarker studies.
