In 1994, Dr. Kevin Hughes and his colleagues wanted to test a treatment for early stage breast cancer in older women. Even though around 40,000 women in the US could qualify for this trial every year, it took Hughes and his team a whole five years to recruit 636 participants. Some time later, Mayo Clinic was planning another study involving breast cancer. The researchers relied on IBM’s Watson for artificial intelligence (AI)-powered clinical trial patient matching and reported an 80% increase in monthly enrollment. If Dr. Hughes would’ve had access to such technology, he would’ve recruited enough participants sooner. Nowadays, pharmaceutical companies benefit from to facilitate their clinical studies’ planning and execution. The global AI-based clinical trials solution provider market is on the rise. It and is forecast to grow at a CAGR of 22% from 2022 to 2030. healthcare AI development services was valued at $1.3 billion in 2021 So, what else can AI do to benefit clinical trials? And what challenges could your organization expect on the way to the technology’s implementation? Why pharma needs a fresh approach to clinical trials Studies show that clinical trials of new drugs and cost around $1.3 billion to carry out. The cost of failed clinical trials, meanwhile, . And the fact that end up failing clinical trials only complicates the matter. last nine years on average ranges between $800 million and $1.4 billion 90% of all drugs In traditional clinical trials, doctors and researchers manually look for participants, and patients have to be physically present to enroll and undergo evaluation. The treatment also occurs on site through scheduled visits. This remains a safe approach to developing new remedies. However, it is slow and lacks the flexibility required to compose complex therapies and address the needs of smaller population segments that are often heterogeneous. Additionally, this approach doesn’t have the capacity to integrate and process data from hospitals, research centers, private practices, and patients' homes. Researchers would struggle with participant recruitment, and would request patients to visit trial sites for systematic condition reviews and monitoring, which could increase the chances of patient dropout. Artificial intelligence and its subtypes can help resolve these issues. How can AI modernize clinical trials? AI can integrate data from multiple sources, including electronic health records (EHRs), research papers, past clinical trials information, and special medical case studies. It can also handle the continuous stream of data from personal medical devices. AI-driven clinical trial technology can aggregate, clean, process, manage, and visualize all this information in a way that helps clinicians understand a given disease and the potential that different chemical compounds offer in countering it. While helps foresee how patients can react to the proposed remedies. predictive analytics in healthcare Gaining access to insights derived from all this information in a timely manner will empower researchers to make more informed decisions fast. Here is how AI can benefit different aspects of clinical trials. Artificial intelligence in clinical trials: top 5 applications Artificial intelligence has many . For example, since the pandemic hit, pharmaceutics extensively used of potential COVID-19 vaccine candidates. benefits in the healthcare sector AI to speed up clinical trials There are five major applications of AI in clinical trials. The technology: Helps design clinical trials Facilitates participant recruitment Supports trial site selection Monitors participants adherence Aids in clinical trial data gathering and analysis 1. AI helps design clinical trials Research shows that poor clinical trial design a potentially efficacious drug from demonstrating efficacy, wasting all the resources spent on developing this medication. can prevent But designing clinical studies is challenging as pharmaceutical companies need to look through vast amounts of data, 80% of which is . AI for clinical trials can help aggregate and process all this data and find useful patterns. For example, it can derive the right regulatory protocols, strategies, and patient enrollment models that suit the country of the trial. AI can also help identify the best timing for conducting the study. unstructured and hard to analyze This will result in encountering fewer protocol amendments, patient dropouts, and regulatory violations. The Tufts Center for the Study of Drug Development found that one substantial protocol amendment and cost between $140,000 and $530,000 depending on the trial’s phase. can prolong a trial for three months 2. AI facilitates participant recruitment in clinical trials There are three main patient-related issues that hinder clinical trials. 1. Candidate patient search Traditionally, patients can hear about relevant trials from their physician or search a corresponding database, like the . These sources are not sufficient, as doctors are not aware of all the ongoing trials and patients might find scrolling over governmental websites overwhelming, especially given their recent diagnosis. national US registry of clinical studies Enhancing clinical trials with AI allows for sifting through patient data, such as EHR and medical imaging, to compare patient characteristics to the study’s eligibility criteria to identify the right individuals for this particular trial. AI is powerful enough to select a homogeneous set of participants, which is challenging with the conventional methods. An AI startup uses its vast database of oncology studies to recruit patients for trials. The startup can match people newly diagnosed with cancer and speed up their enrollment in trials. While , a personal genetics company based in California, suggests clinical studies to its clients based on their genetic makeup. Deep Lens 23andMe 2. Patient dropout Research shows that approximately 30% of participants tend to quit clinical trials. This results in increased expenditure and time needed to complete the study. Recruiting one patient for a clinical trial , while replacing a patient when the trial is already underway costs even more. We can resolve both of these issues with a rigorous patient selection. costs on average $6,500 As mentioned in the previous point above, AI investigates patient data and can look beyond the study’s admission criteria, minimizing future dropout. 3. Patient evaluation Candidate participants need to go through evaluations to ensure they meet the inclusion criteria, which demands their physical presence. And depending on their location and job flexibility, they might not be able to visit the trial’s facilities in the dedicated time. AI can streamline wearable technology deployment, allowing patients to take some evaluations at home. Then machine learning algorithms can aggregate and analyze the data. For example, a medical startup offers connected examination tools and underlying mobile apps that enable patients to capture measurements from their lungs, heart, skin, throat, etc. and send it to clinicians. TytoCare 3. AI supports clinical trial site selection AI can analyze data on available doctors, patients, and climate conditions at different geographical locations and visualize it on a map, which helps pharma companies select an investigator site with the biggest potential. One example of using artificial intelligence in site selection . This clinical trials AI company helps pharmaceutical firms design and prepare for studies with its Clinical Trial Comparator technology. It offers dashboards for visualizing information that helps prioritize sites for prospective clinical studies, including proximity to competitor clinical trials, geography, and candidate population. Innoplexus also developed a customized AI-powered dashboard with filters that allows its clients to integrate third-party data and set thresholds and metrics for their own site selection criteria. comes from Innoplexus 4. AI monitors participant adherence in clinical trials Medication non-adherence is rather common. Studies indicate that their long-term chronic medication as instructed. And according to the World Health Organization, medication adherence can have an even bigger impact than the treatment itself. 50% of Americans fail to take In clinical trials, the process of manually tracking medication adherence is prone to error, as it relies on patients’ memory. And doctors often use unreliable recording systems, such as pen and paper, which can lead to information loss. Deploying wearables together with clinical trial AI allows researchers to monitor patients’ actions through automated data capturing instead of waiting for the patients’ manual reports. For instance, , one of the prominent AI clinical trial companies, developed an interactive medical assistant that can spot patients at risks of non-adherence. This technology also allows patients to take a video of themselves swallowing a pill as a proof that they actually did it. The assistant can identify the right patient and the pill, confirming adherence to the responsible doctor. AiCure To motivate patients and encourage adherence, built a smart medication bottle supported by a mobile app. This technology reminds patients when it's time for medication intake, tracks their dosage, and supplies educational materials. It can also communicate with clinicians to report patient feedback. optimize.health 5. AI aids in clinical trial data gathering and analysis Clinical trials consume and output massive amounts of data. Every participant would generate excessive information, such as adherence data, vital signs, and any other intermediate feedback. AI can aggregate, analyze, and present it to clinicians in a readable format. Also, with the help of and the , clinicians can monitor patients in their home in real time. This means processing large amounts of data daily. AI can take over this task and spot and report any deterioration in patients’ condition, ensuring patient well-being and minimizing dropouts. medical IoT devices Internet of Bodies Another interesting benefit is that machine learning algorithms can identify patient cohorts within a trail that merit further investigation. For instance, if the trial doesn’t seem to yield the expected results, AI can identify participants with specific conditions that seem to benefit from the investigated drug or treatment for sub-trials. A few words about challenges of using AI in clinical trials Lack of interoperability in medical data Despite the efforts put into unifying medical data, there are still multiple , and is still a challenge. This makes it hard to integrate patient information from medical organizations that use different EHR software. Not to mention that some doctors still rely on handwritten notes. healthcare IT standards health data interoperability Even though AI’s operations are hindered by lack of interoperability, the technology can also help overcome this problem. Natural language processing (NLP)-based models can extract clinical data, such as symptoms and diagnosis from diverse heterogeneous sources, and aggregate this information into the trials database instead of normalizing health records and other sources. One example is , which uses NLP to parse diverse EHR systems. The company was valued at $140 million in its latest fundraise. Deep 6 AI However, the job of NLP algorithms is not that straightforward as there is no unified terminology that doctors use to express the same concept. For instance, some physicians refer to a heart attack as “myocardial infarction” or “myocardial infarct,” while some just jot down “MI.” Therefore, clinical trial AI models need to be equipped to recognize all these variations. AI-related challenges AI has its specific difficulties that it brings to every field where it is applied. If you want to discover more about AI, check out our recent article on and . AI implementation challenges how much AI costs Here are two of the most relevant challenges artificial intelligence brings to clinical trials: Training machine learning algorithms At the moment, there is still no reliable, fully-automated replacement for the manual data annotation process required to train artificial intelligence models used in clinical trials. This task is time-consuming, and the results are often tailored to individual healthcare providers or specific diseases. said Noemie Elhadad, a Biomedical Informaticist at Columbia University, emphasizing the limited reusability of trained NLP models. “Right now, there is no such thing as an NLP engine that takes any clinical notes written from any physician and can understand what the notes say,” AI bias and necessity for constant evaluations if the training dataset is not representative of the actual population, as the generalizability of the model depends on the diversity that it saw during training. For example, improperly trained models can skew site suggestions for clinical trials or can perform poorly on patients with darker skin tones. AI can develop bias Even algorithms that are well-trained can acquire bias as they continue to learn on the job. Therefore, it is important to conduct timely independent audits to catch on any inappropriate behavior and eliminate it. , Principal Research Scientist at Massachusetts Institute of Technology. He believes that AI and machine learning in clinical trials need to be viewed as a separate product, independent of the medical devices the technology is used with. Therefore, AI-powered solutions have to be assessed independently and frequently. “AI is a living medical product that needs to be constantly tweaked and recalibrated,” says Dr Leo Anthony Celi The future of AI-powered clinical trials three waves of improvement in traditional clinical trials, some of them will take a long time to mature. Accenture predicts The first wave will bring a significant improvement in trials’ effectiveness due to emerging technology, such as augmented reality (AR), and access to real-time patient data, which AI will help maintain and analyze. , and the consultancy firm is particularly hopeful for AR and VR usage in patient adherence monitoring. AR already has several applications in the healthcare sector The second wave implies that trails will become virtual. This means that researchers could rely on AI-powered digital agents to recruit patients, check them for eligibility, obtain formal consent, and perform onboarding-related tasks. There will be decentralized data repositories with high security and ownership awareness. Patients will fully own their data and share it with clinicians on their terms. In the third wave, trials will be conducted without any risks to patients, as AI algorithms will model clinical outcomes. Fully automating clinical trials with artificial intelligence is still far in the future, but we already witness attempts of AI-based in vitro testing. A biotech company specializing in organ-on-a-chip technology reached out to ITRex to assist in building a platform for in vitro disease modeling and drug testing as a part of clinical trials. This technology relies on chips with microfluidic cells that mimic human organs. Our team , front-end and back-end software for trial design, management, and . helped develop embedded IoT software for the organ-on-a-chip platform data analytics The resulting innovative clinical trials AI solution was adopted by more than 100 labs, including the top US pharma companies, and helped them accelerate drug development and reduce costs. Even if some predictions by Accenture seem futuristic, you can already start incorporating artificial intelligence in clinical trials today. You can turn to AI for clinical trials consulting companies to streamline patient recruitment, monitor adherence, analyze and visualize clinical data, and make patients comfortable with in-house monitoring thanks to wearables. Moreover, you can deploy AI to automate the maintenance of biological materials used during trials. Such AI solutions can be trained to make informed decisions on how and when to split cells, for example. This goes to show that AI involvement in clinical trials is not limited to the applications mentioned in this article. If you have something different in mind, don’t hesitate to reach out.
