Abstract
The foundation of medical research is clinical trials, which offer crucial information on the efficacy and safety of novel therapies and devices. However, there are several issues with traditional clinical trials, such as exorbitant expenses, protracted schedules, and restricted patient accessibility. The representativeness and quality of the data gathered may be jeopardized by factors such as geographic restrictions, strict procedures, and high participant burden, which frequently lead to recruitment problems and high dropout rates. Furthermore, centralized data processing and storage systems are a major component of traditional trials, which raise concerns about privacy, data security, and regulatory compliance. By using digital technologies and remote monitoring tools to conduct trials outside of conventional clinical settings, decentralized clinical trials (DCTs) present a viable answer to these problems. By allowing patients to participate from their homes, DCTs can improve participant engagement and retention through the use of wearable technology, telemedicine, and mobile health applications.
By simplifying the hiring, data gathering, and monitoring procedures, this change not only increases access to a wider range of populations but also lowers operating expenses and speeds up timeframes. To optimize these advantages, artificial intelligence (AI) must be incorporated into DCTs. Rapid data processing, patient monitoring, and predictive modeling are made possible by AI-driven analytics, which also offer real-time insights that improve decision-making and flexible trial designs. AI also makes it easier to stratify patients and create customized engagement plans, which lowers participant attrition and boosts trial effectiveness overall. By guaranteeing safe, transparent, and impenetrable data storage, blockchain technology can also support DCTs, protecting patient privacy while adhering to legal requirements. In summary, blockchain and AI-enabled DCTs have the potential to completely transform clinical research by overcoming many of the drawbacks of conventional trials and bringing clinical research closer to patients. These developments open the door for a more effective and patient-centered approach to clinical research, which in turn speeds up the journey from discovery to clinical application by increasing accessibility, strengthening data integrity, and facilitating quicker, more adaptable studies.
Clinical Trials—Evolution, Current Models, and Limitations
Developing safe, efficient therapies and expanding medical knowledge depend heavily on clinical trials. Clinical trials are defined as human subjects’ research studies that evaluate the safety, effectiveness, and possible adverse effects of novel interventions, such as medications, surgeries, and behavioral therapies. These studies are subject to strict ethical and scientific regulations that are enforced by the U.S. Food and Drug Administration (FDA) and international health authorities.1,2
Phases of Clinical Trials
- Phase I: This phase evaluates safety and dosing in a small group of healthy volunteers or patients.
- Phase II: Phase II trials involve more participants and focus on efficacy and side effects.
- Phase III: Phase III trials are larger and compare the new intervention against current standards or placebos. These trials often provide the evidence required for regulatory approval.
- Phase IV: Conducted post-approval, Phase IV trials gather information on long-term effectiveness, risks, and benefits in a larger, diverse population.
The goals and designs of clinical trials vary greatly, and each type has a specific function in the research and drug development process. Typical formats consist of the following.
Interventional Trials
These studies evaluate particular interventions on subjects, usually contrasting a novel treatment with an established standard or a placebo. One well-known example is randomized controlled trials (RCTs), in which participants are randomized to either the treatment or control groups to reduce bias and guarantee high validity.3
Observational Trials
Observational studies don’t use experimental therapies like interventional trials do. Over time, participants are observed by researchers, who gather unhindered data on particular health consequences. The long-term consequences of medicines, risk factors, and disease development are all better understood and attributed to these studies.4
Adaptive Trials
Adaptive trials modify key trial aspects (e.g., sample size, randomization) based on interim results. This flexible design can increase efficiency, speed, and the relevance of findings.5
Pragmatic Trials
Designed to evaluate effectiveness in real-world settings, pragmatic trials involve broad eligibility criteria and often have fewer restrictions, thereby offering insights into how treatments work in routine clinical practice.6 A clinical trial’s design is fundamental to its validity and scientific rigor. In addition to having different applications, benefits, and drawbacks, different designs also provide distinctive insights. The research topic, the goals of the study, and the trial’s practical limitations all play a role in choosing the best design. Here, some popular clinical trial designs and their advantages and disadvantages are discussed below.
Randomized Controlled Trials
Overview: Because of its reputation for reducing bias, RCTs are the gold standard in clinical research. The intervention under test or a control (such as a placebo or conventional treatment) is given to participants at random in an RCT. By reducing confounding variables, this randomization makes claims on causality more certain.7
Benefits
- Reduces Bias: Blinding and randomization lessen selection and observation biases, increasing the validity of findings.
- High Internal Validity: RCTs offer compelling proof that an intervention causes results.
- Regulatory Acceptance: Regulatory authorities generally accept RCTs as offering high-level evidence because of their meticulous design.8
Drawbacks
- Cost and Complexity: Conducting RCTs, particularly large, multicenter trials, can be costly and time-consuming.
- Ethical Restrictions: In extreme or life-threatening situations, it may be morally problematic to use a control group, which is typically a placebo.
- Limited Generalizability: RCT results may not transfer well to larger, real-world populations because of stringent eligibility requirements.9
Crossover Trials
To minimize carryover effects, participants in a crossover trial receive many therapies in a sequential order, separated by a “washout period.” This design enables each participant to act as their own control and is very helpful for researching therapies for chronic diseases.10
Benefits
- Decreased Variability: Crossover trials can lower variability and possibly need fewer participants by letting participants serve as their own controls.
- Effective Use of Resources: Compared to parallel RCTs, fewer participants and resources are frequently needed.
Drawbacks
- Risk of Carryover Effects: Results may be impacted by lingering effects from prior treatments, even during washout periods.
- Unsuitable for Some Conditions: In general, crossover trials are not useful for curative or acute therapies if the disease may alter over time.11
Cluster-Randomized Trials
Overview: Rather than randomly assigning participants to groups, or “clusters,” cluster-randomized trials (CRTs) do so. For instance, it is possible to randomly assign different towns or hospitals to various interventions, which is especially helpful for public health initiatives.12
Benefits
- Effective for Group-Level Interventions: CRTs are perfect for organizational or community-level interventions.
- Minimizes Contamination: CRTs lessen the possibility of contamination between intervention and control groups by randomly assigning clusters.13
Drawbacks
- Complex Statistical Analysis: To take intra-cluster correlation into account, CRTs need certain statistical techniques.
- Greater Sample Size Requirements: Compared to individual randomization methods, CRTs may need a larger sample size in order to reach enough statistical power.
Adaptive Trials
Overview: Based on interim data analyses, adaptive trials are adaptable and permit changes to the trial’s protocols (such as sample size, dosage, or treatment groups). The goal of this strategy is to improve participant ethics and efficiency.14
Benefits
- Enhanced Efficiency: By permitting modifications in the middle of a study, adaptive designs can lead to quicker findings.
- Ethical Benefits: Ineffective treatments can be discontinued early, and more participants can benefit sooner if effective treatments are identified early.15
Drawbacks
- Risk of Bias: If not properly managed, frequent interim evaluations and adjustments raise the possibility of bias.
- Regulatory Complexity: Because adaptive trials are adaptable, they are subject to regulatory scrutiny, and trial design needs to be carefully pre-specified.16
Non-Inferiority Trials
Non-inferiority studies seek to ascertain whether a novel treatment is not, by a certain margin, inferior to an established treatment. When a placebo is unethical and the objective is to demonstrate that the novel intervention is “good enough,” this design is frequently employed.17
Benefits
- Non-inferiority trials, which do not employ a placebo, enable comparison to conventional treatments, making them ethical for severe conditions.
- Encourages Gradual Progress
- Beneficial for assessing therapies that might be simpler to administer or have fewer adverse effects.18
DrawbacksComplex Analysis
- It can be challenging to determine non-inferiority margins and understand findings.
- Risk of Misinterpretation
- Careful analysis is necessary to prevent drawing false conclusions, as results indicating non-inferiority may not imply that the treatment is superior.19
Clinical Trial Design—The Problems with RCTs
While RCTs are the gold standard in the world of clinical trials, much appreciated by the medical community and the regulatory agencies for their scientific rigor and statistical power accounting for reliable outcomes, the complexity of recruiting, retention, and conducting such studies due to cost, availability of defined study populations, and the inability to complete such studies within appreciable timelines are major hurdles. These impediments have enabled the development of “master protocols” or overarching studies that can spread across multiple interventional studies based on a defined biomarker or disease entity.20,21 Master clinical protocols (MCPs) are novel trial designs that enable the assessment of several diseases, therapies, or subpopulations characterized by biomarkers under a single overall study framework. With the emergence of customized medicine, MCPs provide a strong foundation for effectively addressing challenging research topics. Platform, umbrella, and basket trials are the three main categories of master protocols; each is designed to meet particular research goals and target audiences.
Umbrella Trials
These studies concentrate on a particular disease or health condition while investigating several targeted treatments depending on subpopulations within that illness that have been identified by biomarkers. Because molecular profiling can reveal unique genetic variants within a single cancer type, this design is very common in oncology.22
Benefits
- Precision Medicine: Targeted therapy research is supported by umbrella studies that match medications to certain biomarkers within a disease, improving therapeutic efficacy and minimizing needless exposure to unsuccessful treatments.23
- Operational Efficiency: By testing several treatments in a single trial infrastructure, resources can be streamlined and fewer trials are required.24
Drawbacks
- Complex Design and Analysis: Managing several treatment arms and subgroups calls for intricate statistical analysis and trial design.
- Recruitment Challenges: Biomarker-based subgrouping can limit eligible participants, especially if the biomarker is rare, potentially prolonging trial recruitment timelines.25
Basket Trials
Overview: Basket trials assess a single treatment for a number of illnesses or ailments, usually those that have a common genetic mutation or biomarker. Basket studies, as opposed to umbrella trials, evaluate a single medicine across several indications by concentrating on a therapeutic target rather than a particular illness.26
Benefits
- Broad Applicability: When a mutation or biomarker is present in several malignancies or disease states, basket trials can be very helpful for rare diseases or disorders.
- Improved Access: Basket studies offer therapy access to a variety of patient groups by enrolling individuals from many disease areas with a shared biomarker, which may hasten patient accrual.27
Disadvantages
- Heterogeneity of Diseases: Differences in disease biology between indications may lead to variable treatment responses, complicating data interpretation.
- Limited Generalizability: A positive result in one subset of a basket trial may not generalize to all indications, particularly if disease mechanisms differ.
Platform Trials
Overview: Platform studies allow for the addition or removal of treatment arms in response to interim data, and they assess several medicines for a single condition. In an ongoing, eternal study structure, this adaptive design enables researchers to effectively evaluate several experimental medicines versus a control group or standard-of-care.28
Benefits
- Adaptive Flexibility: Platform trials allow treatment arms to be added or removed with ease, keeping the trial up to date and in line with new scientific findings.29
- Enhanced Efficiency and Cost Savings: By avoiding the need for different trial setups, sharing infrastructure and control groups across many arms lowers the overall cost and time needed to test new medicines.30
Drawbacks
Statistical and Regulatory Complexity: Because platform trials are adaptive, they are subject to extra regulatory scrutiny and need careful statistical preparation to account for Type I error across several treatment comparisons.31
Risk of Resource Burden: Although effective, the intricacy of overseeing several concurrent arms may present logistical and operational difficulties, particularly when it comes to synchronizing data among several treatment groups.
Benefits of Master Protocols
- Accelerated Drug Development: MCPs are made to speed up testing and development by enabling researchers to assess several interventions or targets in a single framework, which reduces recovery time.32
- Optimized Resource Use: MCPs reduce resource costs and increase data gathering by utilizing centralized trial infrastructure and shared control groups, which is especially advantageous in rare diseases or small patient populations.33,34
- Benefits for Ethics: MCPs eliminate the need for numerous control groups, which may expose fewer individuals to placebo. This is particularly helpful for critical illnesses for which there are few effective treatments.35
General Drawbacks of Master Protocols
- Complexity and Setup Cost: While MCPs can save resources once they’re up and running, they require complex statistical frameworks, biomarker testing, and trial designs, which can raise setup costs.
- Difficulties in Interpreting Data: Using several arms, biomarkers, or illnesses in a single procedure might make statistical analysis more difficult and necessitate sophisticated approaches to properly interpret the results.
- Enhanced Regulatory Scrutiny: Because of their unique structure and adaptability, MCPs are frequently the focus of thorough regulatory review, which may cause delays in the start of studies and the need for continuing management.
Limitations and Drawbacks of Traditional Clinical Trials
Time and Cost: Clinical trials, particularly Phase III studies, are time-consuming and costly procedures that can take years to finish. These temporal and financial constraints frequently limit access and postpone the release of promising therapies by limiting trial participation to well-funded institutions or organizations.36
Patient Recruitment and Retention: It might be difficult to find and keep participants, especially in uncommon conditions where there are fewer eligible patients. Furthermore, the rigorous character of certain studies may cause participant dropouts, which may compromise statistical power and the reliability of results.37
Risk and Ethical Issues: It might be difficult to strike a balance between scientific rigor and ethical issues in trials when volunteers might get placebos or suffer negative side effects. Withholding potentially beneficial therapies raises ethical concerns, especially in life-threatening illnesses.38
Generalizability: The fact that many clinical trials are carried out in well-regulated environments with stringent inclusion and exclusion standards may restrict their applicability to populations in the real world. Although pragmatic trial designs are still uncommon, this constraint has encouraged their usage.39
Risk of Bias and Confounding: Even with randomization, confounding variables can still affect some trials, especially in observational research. Furthermore, the medical literature may still be skewed by publication bias, which occurs when only good results are reported.40
Some solutions to existing issues with traditional clinical trials can be addressed by DCTs.
DCTs and Their Modalities
Clinical investigations carried out fully or in part outside of conventional research facilities are known as decentralized clinical trials, or DCTs. DCTs use remote technology and resources to engage participants wherever they are, in contrast to traditional clinical trials that typically require participants to travel to a central location (such as a hospital or clinical research facility) for each study-related activity.41 This change is intended to facilitate real-world, continuous data gathering, ease logistical difficulties, and make participation simpler and more accessible (Figure 1).

Important Elements of DCTs
DCTs usually use a number of cutting-edge techniques to interact with participants and collect data, such as:
- Telemedicine and Virtual Visits: Study staff can communicate with participants remotely for enrollment, follow-up, and even some assessments using video calls or phone consultations.
- Wearable Sensors and Devices: Wearable sensors and devices such as heart rate monitors, glucose meters, and fitness trackers can automatically record health data. This eliminates the need for in-person visits by enabling researchers to collect continuous, real-time data on participants’ vital signs, physical activity, and other metrics.
- Mobile Health Apps and Electronic Patient-Reported Outcomes (ePROs): Using a smartphone or other electronic device, participants can record their own data, report symptoms, and respond to questionnaires through mobile apps and ePROs.
- Home Health Services: Mobile health professionals can come to research participants’ homes to conduct physical examinations, take blood samples, or give study drugs.
- Direct-to-Patient Drug Delivery: Instead of requiring participants to come to the trial location for every dose or cycle, medications or other study-related materials are frequently sent straight to their homes.
Benefits of DCTs
The DCT approach has several benefits.
- Enhanced Accessibility: People from a variety of social, economic, and geographic backgrounds can participate more easily in DCTs since they eliminate the need for travel and in-person visits. Higher levels of satisfaction and reduced dropout rates are frequently the results of allowing patients to participate in studies with less interference with their daily life.
- Cost and Time Efficiency: DCTs can speed up participant recruiting and trial execution while lowering the administrative and logistical expenses related to physical facilities.
- Real-World Data Gathering: Ongoing, remote data gathering offers significant information about how therapies function in actual settings, which is crucial for assessing lifestyle impacts and long-term effects.
Challenges of DCTs
Notwithstanding their advantages, DCTs have some drawbacks.
- Data Security and Privacy: As our reliance on digital tools grows, safeguarding patient information and upholding confidentiality become crucial issues. Digital literacy and access to dependable internet are prerequisites for participation, as is the ability to use digital platforms, which can be difficult for some groups to access.
- Regulatory and Compliance Issues: As it relates to data accuracy, patient safety, and the legitimacy of remotely gathered data, regulatory bodies are still modifying their rules to allow DCTs.
- Data Integration and Quality: It can be difficult for researchers to manage massive amounts of data from several sources (such as wearables, ePROs, and electronic health records (EHRs)) while maintaining consistent quality and interoperability.

The Function of Blockchain Technology in Facilitating DCTs
Blockchain technology is a distributed ledger system that stores data via a decentralized network. It was first created for safe and transparent bitcoin transactions. This structure provides important benefits such as data immutability, transparency, and security. It is frequently made up of a series of encrypted “blocks” of data. Because of these characteristics, blockchain is a great option for enhancing the administration and operation of DCTs, where participant involvement and data integrity are crucial.
An Overview of Blockchain for Security and Data Integrity
Data entries can be made in a permanent, visible, and secure manner thanks to blockchain’s decentralized ledger. Each block is cryptographically connected to the previous one, meaning that any changes to the content must be approved by the network, which helps prevent data manipulation. This feature is useful for DCTs, where data must be continuously collected from remote participants while remaining secure and verifiable. By utilizing private and permissioned blockchains, such as Hyperledger Fabric, researchers can manage access to sensitive data while maintaining the transparency required for regulatory compliance.42
Smart Contracts for Automated Workflows and Dynamic Consent
The blockchain’s self-executing smart contracts make it possible to manage participant consent and trial procedures effectively. By enabling real-time revisions of participant consent preferences in DCTs, these contracts guarantee that researchers can monitor any modifications to study participants’ participation. Furthermore, smart contracts reduce the possibility of human error and improve transparency by automating a variety of trial procedures, such as initiating data-gathering events and carrying out payments. Enhancing patient involvement and streamlining intricate trial logistics depends on this characteristic.43,44
Improved Regulatory Compliance and Data Privacy
In clinical trials, where patient data privacy is crucial, blockchain technology’s capacity to offer safe, decentralized data storage options is especially crucial. Blockchain’s ledger is supplemented with decentralized storage systems, such as the interplanetary file system, which store large amounts of data off-chain, lowering costs, and improving scalability without sacrificing verifiability. By offering an auditable record of all transactions and data exchanges, blockchain also facilitates regulatory compliance, making it simpler for regulators and researchers to keep an eye on the trial’s progress and guarantee data integrity.45
Data Sharing and Interoperability
Blockchain allows for seamless data sharing among various stakeholders—pharmaceutical companies, clinical research organizations, and regulators—by ensuring that all parties have access to the same data version in real time. This lowers data reconciliation mistakes and eliminates the need for middlemen, which is especially beneficial in the decentralized and hybrid trial formats that have become popular during and after the COVID-19 pandemic.46
Contributions of AI to improve DCTs
DCTs are being transformed by artificial intelligence (AI), which improves patient experience, data gathering, recruitment, and retention. Here are some effects of AI that are backed up by pertinent research.47–53
Improved Recruitment and Retention
Locating and keeping participants is one of the major obstacles in clinical trials. AI makes this process easier by sifting through massive datasets to find qualified patients more quickly. AI algorithms can use real-world data from social media, EHRs, and other sources to match patient characteristics with trial needs. This shortens the time needed to enroll patients and increases the accuracy of patient selection. Research has shown that AI-driven tools in recruitment not only optimize efficiency but also mitigate bias in patient selection by expanding the pool of participants across diverse demographics and geographic locations, which is essential for decentralized models that aim to be more inclusive and representative of the general population. In the field of oncology, companies like Tempus have employed AI to better target underserved populations in clinical trials. Using AI to analyze EHRs, Tempus was able to identify minority patients with rare forms of cancer who were otherwise missed by traditional recruitment methods. By matching these patients to appropriate trials, the company was able to improve diversity in cancer research and treatment outcomes. Verily Life Sciences, a subsidiary of Alphabet, has been integrating AI and machine learning into clinical trials, including multilingual and multinational efforts. In their research, AI tools helped translate complex medical information into over 20 languages, making clinical trials more accessible to diverse patient groups globally.
Automated Data Gathering and Monitoring
AI facilitates automated data processing and patient-reported outcome monitoring, which are essential components of decentralized trials that depend on distant data gathering. Clinicians can keep an eye on patients’ health in real time by using AI systems to evaluate data from wearable devices and track parameters like heart rate or physical activity. This results in safer and more successful trials by lowering the need for in-person visits and assisting in the early identification of problems. In large-scale decentralized trials, AI’s contribution to data monitoring is very beneficial in enhancing data integrity and lowering errors. Data processing AI analyzes and combines many data sources, including patient-reported outcomes, wearables, and EHRs. Faster insights are made possible by Medable’s platform, which uses AI to harmonize real-time data from many sources in DCTs. For example, it assisted a trial sponsor in handling data from wearable technology and telehealth while cutting down on recruitment time by 50%.
Case Study: Virtual Trials at Pfizer
In order to ensure smooth data integration across digital touchpoints, Pfizer’s REMOTE experiment employed AI-driven technologies to remotely gather and process data from rheumatoid arthritis participants. AI ensures real-time tracking of health parameters by enabling remote patient monitoring using wearable technology and Internet of Things-enabled technologies. Wearable sensors are used by Biofourmis’ AI-powered platform to continuously monitor patient vitals like temperature and heart rate. It assisted in identifying early indicators of decline in a COVID-19 experiment.
Case Study: Wearable Technology Experiments at Novartis
In its multiple sclerosis trials, Novartis employed AI to evaluate wearable data, providing ongoing patient monitoring without frequent clinic visits.
Predictive Modeling: AI aids in trial design optimization by forecasting outcomes like disease progression or patient reactions to therapies. BenevolentAI uses machine learning to forecast patient reactions and possible medication candidates. It recognized baricitinib as a potential COVID-19 therapy during the epidemic.
Case Study: Health Flatiron
AI is used by Flatiron Health to forecast the outcomes of cancer patients based on empirical data, which helps with the design of clinical trials for oncology research. By keeping an unchangeable record, blockchain stops unwanted data changes. Triall uses blockchain integration to protect clinical trial data, guaranteeing the provenance and immutability of each data piece. Without the need for middlemen, trial sponsors can confirm the accuracy of data submissions.
Pfizer and Boehringer Ingelheim as a Case Study
Blockchain technology was employed by both businesses to protect private clinical trial data, guaranteeing that the data would not be changed during the trial.
Protection of Privacy: Blockchain uses decentralized identification and cryptography techniques to protect patient privacy. Embleema gives patients authority over their data while securely sharing and anonymizing information with trial sponsors via blockchain.
Case Study
The MedRec Project at MIT MedRec employs blockchain technology to keep a safe, decentralized patient record repository. To exchange encrypted patient data with researchers while maintaining anonymity, this system was tested for clinical trials.
Transparency and Compliance: Real-time, traceable logs for data sharing and regulatory compliance are made possible by blockchain. To provide auditability for regulatory agencies, IBM and Hyperledger collaborated to develop a blockchain-based system that follows each stage of clinical trials. Blockchain technology was employed by Bayer to guarantee traceable and transparent data sharing during clinical trials. The system improved stakeholder confidence and expedited consent management.
Enhancing Patient Experience: AI also makes the trial process easier for patients by giving them access to chatbots, digital assistants, and applications that provide support, reminders, and direction during the study. It has been demonstrated that this strategy increases participation because it makes participants feel more knowledgeable and connected, both of which are critical for long-term retention. DCTs are a feasible option for people who might not otherwise be able to participate since AI lessens the stress on patients by personalizing interactions and streamlining intricate procedures.
Language and Cultural Adaptation: Real-time translation and cultural contextualization of trial materials, including consent forms and teaching materials, are made possible by AI-powered natural language processing. AI techniques, for instance, might modify information to accommodate regional dialects and idioms, guaranteeing that trial participants comprehend and are at ease with the procedures.
Enhancing Accessibility: By providing user-friendly interfaces and multilingual support, AI-driven platforms, such as Medable’s solutions, simplify virtual trial participation and lower obstacles for participants who do not understand English. For example, in Asia-Pacific, ObvioHealth and Oracle’s partnership made it possible to integrate a variety of data for trials, increasing accessibility across cultural boundaries. U.S. National Institute of Health (NIH) and FDA have worked on initiatives to increase representation in clinical trials. AI systems have been used to identify patients in underrepresented communities, especially in trials for cancer treatments and rare diseases. AI helped predict which communities were most likely to benefit from new treatments and designed culturally sensitive recruitment campaigns, leading to more equitable participation.
Cost and Time Efficiency: AI reduces the logistical and financial obstacles that decentralized trials have historically faced by automating time-consuming processes like data entry and eligibility screening. Clinical trials might be shortened by up to 10% using AI-driven automation, according to research, which would save money and speed up trial results. AI-powered logistics also make trial coordination easier and increase scalability in a decentralized approach where trials take place in multiple locations.

- Impact: The trial demonstrated how a fully decentralized model could reduce operational burdens and significantly improve timelines and patient access.
Verily Life Sciences conducted a hybrid study on diabetes management in collaboration with virtual health platforms. This trial used a combination of home-based glucose monitoring, telemedicine consultations, and digital symptom tracking.
Key Results
- Cost Savings: The trial leveraged remote monitoring and digital tools to reduce costs associated with in-person visits, which are traditionally a significant portion of trial expenses. By eliminating the need for centralized trial sites, the trial saved on overhead, staffing, and patient travel reimbursements.
- Time Reductions: Data collection and analysis were streamlined using wearable devices, allowing for faster data processing and real-time insights. The trial was able to reduce the study duration by 4 months.
- Patient Engagement and Retention: Participants appreciated the ease of monitoring their diabetes from home, and retention rates were higher than in traditional trials. Recruitment was faster due to broader outreach, with patients able to participate from home.
- Impact: The case study highlights how remote health tools not only reduce costs and time but also improve patient engagement and data accuracy.
Eli Lilly ran the EVOLVE-3 trial for a rheumatology drug using a decentralized design with telemedicine and remote monitoring of clinical outcomes. Patients completed assessments via an app, while mobile health professionals visited participants’ homes.
Key Results
- Cost Savings: The use of remote monitoring and home visits saved approximately 25% of the typical costs related to patient recruitment and clinical site management.
- Time Reductions: With fewer in-person visits required, the recruitment process was faster, and the study timeline was shortened by 4 months. Digital tools enabled continuous data collection, reducing gaps and delays.
- Improved Patient Experience: By reducing the burden on patients to travel to clinics, Eli Lilly saw better patient satisfaction and higher completion rates.
- Impact: The study demonstrated that even for complex diseases requiring ongoing treatment and monitoring, a decentralized approach could streamline operations, cut costs, and improve patient retention.
Conclusion
A paradigm change in clinical research, DCTs have the potential to greatly increase the effectiveness, accessibility, and inclusion of trials for a variety of populations. DCTs overcome many of the geographical and logistical constraints that restrict participation in conventional trials by leveraging digital and remote tools. DCTs’ potential is further enhanced by the use of blockchain technology and AI, which adds levels of data protection, integrity, and analytical capability. Trial data is kept in a safe, tamper-proof environment thanks to blockchain’s immutability and transparency, protecting patient privacy and improving regulatory compliance. AI-driven analytics, on the other hand, enable quicker and more precise insights from intricate datasets, promoting in-the-moment decision-making and improving patient outcomes. When combined, these technologies allow for more patient-centered, flexible, and dynamic clinical trials, which eventually speeds up the conversion of research findings into clinical practice. To address obstacles pertaining to data interoperability, regulatory frameworks, and user adoption in the future, cooperation between regulatory agencies, technological developers, and healthcare stakeholders will be crucial. DCTs backed by blockchain and AI have the potential to revolutionize clinical research and help create a more effective, inclusive, and individualized approach to clinical medicine with continued work.
