DCTs have the potential to overcome these challenges by expanding the recruitment pool beyond the limited geographic area close to trial sites. By including participants from remote areas, DCTs enhance diversity in study populations and improve the generalisability of results
  • Regulatory acceptance and guidelines: Regulatory agencies, recognising the benefits of DCTs, have issued guidelines to support their implementation. For example, the FDA and the EMA have released instructions on decentralised trials, providing recommendations on data integrity, patient privacy, remote consent, and other considerations. These guidelines have fostered confidence among sponsors and investigators, facilitating the wider adoption of DCTs
  • Learnings from the COVID-19 pandemic: The COVID-19 pandemic accelerated the adoption of remote approaches in clinical trials. With travel restrictions and safety concerns, traditional trial operations faced significant disruptions. DCTs emerged as a viable alternative, enabling researchers to continue studies remotely. The successful implementation of DCTs during the pandemic has highlighted their potential and paved the way for their continued use even beyond the pandemic

 What are the key benefits and advantages of conducting decentralised clinical trials compared to traditional site-based trials?

Revolutionising clinical research, DCTs have surfaced and presented unparalleled benefits that disrupt traditional approaches. It has demonstrated numerous advantages such as:

  • Improved patient access and convenience: DCTs offer heightened accessibility and convenience by cutting down on the frequency of travel to clinical trial sites
  • Enhanced patient retention: Maintaining patient retention in clinical trials is a frequent obstacle, often arising from demanding visit schedules, travel obligations, and logistical complexities. DCTs address these challenges by offering a patient-centric experience that alleviates these burdens
  • Cost and time efficiency: DCTs achieve cost-minimisation in operations by doing away with the requirement for physical trial sites and decreasing on-site monitoring
  • Real-time data collection and analysis: By enabling real-time data collection and prompt analysis, researchers are equipped to make informed decisions during the trial, leading to the development of more efficient and adaptive protocols

 How does the use of technology enable remote patient monitoring and data collection in DCTs?

The use of technology plays a critical role in enabling remote patient monitoring and data collection in DCTs. Through digital health tools such as mobile applications, wearable devices, and connected sensors, participants can track and transmit real-time health data from their homes. EHRs facilitate securing the sharing of patient information between healthcare providers and trial sponsors.

Additionally, telemedicine platforms make it easier for people to have virtual consultations instead of in-person appointments. With remote data capture tools like electronic case report forms (eCRFs) and electronic patient-reported outcome (ePRO) systems, participants can directly enter their data and responses into digital forms. By integrating data from various sources like wearable devices and EHRs, valuable insights can be derived through real-time analysis. Measures are taken to ensure secure data transmission and maintain privacy to protect participants’ information. In essence, the integration of technology in DCTs enhances participant convenience, improves data quality, and optimises trial operations through remote monitoring and data collection.

 How do DCTs improve patient recruitment and retention compared to traditional trials?

DCTs expand participant accessibility by allowing individuals to engage in trials from their homes or local communities, eliminating geographical barriers. This broader reach increases the potential participant pool and enhances diversity in study populations. Additionally, the convenience of participating remotely reduces the burden on participants, resulting in higher engagement and improved retention rates. By minimising the need for frequent in-person visits and associated travel costs, DCTs enhance convenience and reduce the logistical challenges that often deter participation or lead to participant dropouts in traditional trials. The flexibility and patient-centric nature of DCTs contribute to increased recruitment rates and better participant retention throughout the trial, ultimately leading to more successful and efficient clinical research.

Additionally, the integration of applications with remote sensor devices allows subjects to virtually record trial-related details, eliminating the need for site visits. The ‘televisits’ feature enables subjects to conveniently engage in discussions with site clinicians, addressing their day-to-day questions and concerns. With the ‘caregiver concept’, patients can grant authorisation for a caregiver to provide their details when direct communication with the site is not feasible. In contrast, web portals provide a convenient solution, allowing patients to remotely log in, complete questionnaires, and record study-related information without the requirement of visiting the site in person. These features enhance accessibility and streamline the participation process in clinical trials.
