Clinical Trial Transformation: Recent Changes and Future Predictions
Clinical trials play a pivotal role in advancing medical research and improving patient care, and are an essential part of new drug development. In recent years, clinical trials have undergone significant changes driven by technological advancements, regulatory shifts and a growing emphasis on patient-centricity.
Accelerated by the COVID-19 pandemic, we have seen a shift in clinical trials, with changes to the way they are conducted, regulated and perceived. In this article, we will explore the recent transformations in the world of clinical trials and offer insights into their potential future direction.
Recent changes in clinical trials
One of the most prominent recent developments in clinical trials is the increasing use of real-world evidence (RWE). RWE uses data from a variety of sources, including electronic health records, insurance claims and wearable devices. This allows researchers to gather data beyond traditional clinical trial settings, providing a more comprehensive view of a treatment’s effectiveness and safety.
The COVID-19 pandemic accelerated the adoption of remote and decentralised clinical trials, also known as virtual, at-home or site-less trials. With the implementation of telemedicine and home-based monitoring, patients can take part in trials from the comfort of their homes, eliminating the need to travel to specific sites. This approach has shown increased patient participation and increased study effectiveness, and will ultimately help to get drugs to market faster.
There has also been a growing emphasis on patient-centricity in more recent clinical trials. Regulatory agencies and sponsors are actively involving patients in the trial design process to ensure that the research is aligned with patients’ needs and preferences. This approach not only enhances the relevance of the trials but also increases patient recruitment and retention rates.
Several countries have undergone significant changes in their clinical trial regulations to adapt to the changing landscape:
United States: In June 2023, the FDA announced the availability of a new draft guidance, ‘E6(R3) Good clinical Practice (GCP)’. The latest draft guidance includes updated recommendations and “encourages innovation, focuses on quality, and establishes proportionate and risk-based approaches for conducting clinical trials, while minimizing unnecessary complexities”. New recommendations include encouraging the use of innovative digital health technologies (DHTs), such as wearable sensors, to increase the efficiency of data collection.
European Union: The EU has implemented a new Clinical Trials Regulation (CTR) to create a more unified and efficient framework for clinical trials across member states. The CTR, fully implemented in early 2023, simplifies the approval process, harmonises trial designs and establishes a single portal for trial submissions. These changes are expected to reduce administrative burdens and enhance the competitiveness of EU clinical research.
India: In 2019, the Ministry of Health and Family Welfare (MoHFW), Government of India released updated New Drugs and Clinical Trials Rules, designed to help streamline regulations and guide clinical trial conduct in India. These updated rules include new time limits for responses to submissions for application for clinical trials.
United Kingdom: Announced in October 2023, a series of new measures will be introduced by the Medicines and Healthcare products Regulatory Agency (MHRA) to streamline clinical trial approvals. Under the new framework, clinical trials application processes in the UK will be more streamlined and flexible without compromising on safety, helping to make it faster and easier to gain approval and to run clinical trials in the UK. The changes will also result in a framework that is responsive to diverse types of trials and designs, and supportive of new ways of conducting trials such as decentralised trials.
Predictions for the future of clinical trials
The future of clinical trials will continue to be shaped by ongoing developments and emerging trends. Here are some predictions on what we think will shape clinical trials in the coming years:
Advanced data analytics: The integration of artificial intelligence and machine learning will revolutionise data analysis in clinical trials. Predictive modelling, data mining and real-time monitoring will enable more efficient trial designs, better patient selection and early identification of safety concerns.
Expansion of decentralised trials: The trend of decentralised and remote trials will expand, making participation more convenient for patients. Regulatory agencies will further support this shift by providing clear guidelines for virtual trials.
Enhanced regulatory flexibility: Regulatory agencies are expected to keep a more flexible approach, enabling faster responses to emerging health crises. Collaborative relationships between the pharmaceutical industry and regulatory bodies are likely to continue evolving to streamline the approval process.
Personalised medicine: Advancements in genomics and biomarker discovery will drive the development of targeted therapies. Clinical trials will need to adapt to consider individual genetic profiles and treatment responses, paving the way for targeted therapies.
Real-world data will be critical in decision-making: Emerging technologies and new devices will enable companies to gather large amounts of real-world evidence. This data, along with data from clinical research, will help to guide pharmaceutical companies’ approach towards clinical trials.
The world of clinical trials has evolved significantly in recent years, with an emphasis on real-world evidence, patient-centricity, and streamlined regulatory processes. These changes have made clinical trials more efficient, patient-friendly and globally connected. The future holds even more promise with advanced data analytics, decentralised trials, global harmonisation and the rise of personalised medicine. As we continue to navigate the ever-changing landscape of clinical trials, the ultimate beneficiaries will be patients who receive safer and more effective treatments because of these innovations.
