Decentralized clinical trials differ from traditional clinical trial model. They are facilitated by telemedicine and mobile/local healthcare providers, transforming traditional approaches by enabling remote monitoring of participants. Decentralized models have several benefits – they not only enhance patient access, but also reduce trial durations and lower costs. Since these trials allow patients to participate from their homes, they remove barriers related to travel and time commitments, eventually leading to faster recruitment and retention.

Adaptive Trial Designs

As the name indicates, ‘Adaptive’ trial designs are designed to allow modification to the trial and statistical procedure of the trial (to adapt) after its commencement without undermining its validity and integrity. The flexibility offered by adaptive trial designs enables researchers to make real-time adjustments to dosage, treatment regimens, or patient populations, all of which can accelerate the approval process.

Wearable Devices and Digital Biomarkers

Wearable devices provide real-time data on health metrics and behaviors. These technologies facilitate continuous assessment of clinical outcomes. This immediate feedback loop supports more dynamic decision-making, contributing to faster clinical evaluations. For instance, the use of Apple Watch in a study helped in monitoring atrial fibrillation in participants. The constant stream of data allowed researchers to assess outcomes without requiring frequent clinic visits, expediting the trial process.
