Previous articles on Clinical Leader have discussed the potential benefits of wearable devices for remote patient monitoring in clinical trials. In addition to possible increases in trial efficiency and reduction of costs, “wearables” have the potential to collect data better reflecting patient functioning and response in the real-world setting. According to the Clinical Trials Transformation Initiative’s Mobile Clinical Trials (MCT) Program, mobile devices, including wearables, offer the opportunity to collect more complete and informative data than ever before. Mobile devices may also reduce the patient burden in clinical trials, thus enhancing the patient experience. Companies are exploring the use of wearable devices in the post-marketing setting as well, as a component of patient care.
