Example: Pfizer continues to lead in decentralized trial architecture via its “Clinical Trial Anywhere” model, which reduces in-person visits by ~50% and achieves ~90% retention rates—well above the 75% industry average. Their cross-functional teams leverage telehealth, mobile units, and local labs to operationalize hybrid trials.
2. Patient Recruitment and Enrolment
Patient recruitment and enrolment in a digital clinical trial leverage the power of technology to reach a broader and more diverse participant pool, addressing one of the most challenging aspects of clinical research. Online recruitment strategies, such as targeted social media campaigns, digital advertising, and partnerships with online health communities, enable researchers to identify and engage potential participants more effectively. This approach not only broadens the reach but also enhances the diversity of the participant population, which is crucial for the generalizability of the trial results.
Once potential participants are identified, the enrolment process is streamlined using electronic informed consent (e-consent) systems. These systems enable participants to review, understand, and sign consent forms digitally, providing a more convenient and accessible method for obtaining informed consent. Additionally, digital platforms can facilitate pre-screening questionnaires and virtual consultations to ensure that participants meet the eligibility criteria before formal enrolment.
Example: Science 37, acquired by eMed in March 2024, supports site-less trials using video chat, e-consent, mobile nurse services, and same-day medication delivery .
3. Data Collection and Monitoring
Data collection and monitoring in a digital clinical trial harness advanced technologies to enhance accuracy, efficiency, and real-time oversight. Participants often use wearable devices, such as smartwatches and fitness trackers, to continuously monitor vital signs, physical activity, and other health metrics, providing a wealth of real-time data that is automatically transmitted to the research team.
Mobile applications further facilitate data collection by allowing participants to log symptoms, medication adherence, and other relevant information directly from their smartphones. These apps can also enable seamless communication between participants and researchers, ensuring timely reporting of any issues or adverse events.
Remote monitoring capabilities enable researchers to oversee participants’ health data in real-time, reducing the need for frequent in-person visits and allowing for prompt interventions when necessary.
Example: Takeda has implemented Smart Tech—a system of smart packaging with sensors to log medication adherence automatically. By integrating this with their data platforms, Takeda ensures precise tracking of compliance.
4. Patient Engagement and Retention
Telemedicine plays a crucial role by offering virtual visits and consultations, which reduce the need for participants to travel and make it easier for them to stay engaged with the trial. This convenience is particularly beneficial for participants with mobility issues or those living in remote areas.
Digital reminders, such as automated notifications for medication adherence, upcoming appointments, and data entry tasks, help keep participants on track and reduce the likelihood of missed activities.
Interactive platforms, including online forums and chatbots, provide participants with continuous support and information, fostering a sense of community and belonging. These platforms can also facilitate real-time communication with the research team, allowing participants to ask questions and receive prompt responses. By creating a more participant-centric experience through these digital tools, researchers can improve engagement and retention rates.
5. Data Management and Analysis
Electronic Data Capture (EDC) systems play a central role by securely collecting, storing, and managing trial data, ensuring that it is easily accessible and organized for analysis. These systems reduce the risk of data entry errors and enhance data integrity by automating many aspects of data collection and validation.
Advanced analytics tools enable real-time processing and analysis of the collected data, allowing researchers to identify trends, monitor progress, and make data-driven decisions promptly. This real-time capability is particularly valuable for interim analyses, where early insights can inform necessary adjustments to the trial protocol or strategy.
