Top 17 Clinical Research Organizations (CRO) in 2023

In clinical research and treatment development, clinical research organizations (CROs) are frequently a sponsor’s most important partner and ally.

Depending on the nature of the clinical trial, and your existing capabilities as a sponsor to run the trial, the CRO company of your choice will typically be responsible for facilitating most of the micro and macro processes that go into designing and running a successful clinical trial.

When contracting a CRO to help you with your trial, you are transferring over a large portion of responsibility into the hands of your clinical research partner. The CRO of your choice will have the responsibility to control a variety of factors and processes of a clinical trial, and depending on their expertise, team structures, service offerings, internal resources and many other capabilities.

Your ability to find and contract a top CRO company that is the right fit for your unique trial will be a determinant of whether or not you will be able to operate a high-quality clinical trial that meets your expected timelines, budget and delivers a top-notch patient experience.

9 Fundamental Questions To Ask A Top CRO Company Before Signing The Contract

1. which services does the cro provide.

CROs offload a lot of operational tasks from trial sponsors, which can touch any component of clinical trial operations. From formulating an overall study strategy and implementing technologies to support the operational processes of the trial, to picking and identifying sites, and supporting patients during the trial, the range of clinical services offered by a CRO tends to be vast and inclusive of all the typical services and support you will require for running a successful clinical trial.

However, not all CROs are the same in their service offerings, or are able to offer the same depth of capability within a seemingly same clinical trial support process. For this reason it is important to understand exactly which kind of clinical services and support you are looking to receive from the prospective CRO when running your clinical trial.

While services such as clinical monitoring and clinical trial management are offered by the majority of CROs, the specific needs of each trial are unique, and for this reason it is important to first identify what will be the unique services your trial requires. Completing this internal analysis first will help you to understand the extent to which a potential CRO partner will be able to provide all of these services.

Some CROs specialize in specific clinical trial functions which the company may label as a “core services”, in which case this is a sign the company will have more expertise, experience, and will be set up in a way to maximize their capabilities in providing support for these services compared to other services that the CRO offers.

For example, a CRO may include patient recruitment as part of its “core services”, which implies that they are highly skilled in and have the necessary infrastructure to design and implement a high-quality patient recruitment strategy.

Clara Health CRO Support Services: At Clara Health our specialty services include technology-augmented digital and patient advocacy recruitment, as well as patient support via our signature patient recruitment platform, which we use to upgrade clinical trials and deliver results sponsors look for in their recruitment and retention campaigns.

At Clara, we work alongside CROs to supplement and support clinical trials with modern and personalized capabilities that CROs do not typically have the bandwidth, corporate structure or infrastructure to support.

If you would like to learn more about exactly how our platform can upgrade your unique trial, feel free to book a Free 30 Minute Consultation Session Here with one of our in-house experts.

2. What Related Experience Does The CRO Have?

It is helpful to ask the prospective CRO company if they have any relevant experience in running clinical trials that would be an asset in designing and running your study. Previous experience in a related therapeutic area or in running a trial with a similar design allows CROs to have a deeper understanding into potential opportunities and challenges, increasing the likelihood of your clinical study being successful.

For example, if a sponsor is planning to run a trial in oncology, for the purpose of site identification and selection it would be valuable to partner with a CRO vendor that has expertise in this area, as they likely already have a good understanding of which sites will lead to optimal results.

However, it is also important to consider all factors when selecting a CRO vendor and not to rely on therapeutic experience as the sole qualifier for whether or not a potential CRO is a fit for your trial. While previous experience is beneficial, some sponsors close themselves off from working with vendors that have not worked in their therapeutic area, which significantly limits options when choosing a CRO partner that is truly a good fit for their clinical study.

This can impact the end result of your clinical study, as sponsors that are not successful in choosing a CRO vendor that is the right overall fit may face difficulties if the needs of their clinical study aren’t being properly met.

Clara Health: We have worked to provide support for clinical trials across a wide range of therapeutic areas and trial designs. Our specialty is filling in the gaps that CROs traditionally did not have to think about, which include digital patient recruitment, patient advocacy recruitment, and technology-augmented patient support.

Additionally, we are constantly building our proprietary data and running tests in a variety of therapeutic areas. These research efforts allow us to have a detailed understanding of the expected level of difficulty when recruiting particular patient populations, as well as allow us to predict with accuracy which segments of the targeted population will be likely to qualify in a particular study.

3. What Are The Communication Workflows & Expectations For Performing And Delivering Contracted Services?

It is important that you clarify what the expectations for communication will be between your prospective CRO vendor and your internal teams, as you will most likely be working with the CRO of your choice for the entire duration of your clinical trial.

There are a vast variety of factors and success determinants for a clinical trial, which are continuously undergoing change as the study unfolds. For this reason, it is recommended that you work with a CRO that is proactive in their communication, so that you are kept up to date with information about important changes as your clinical trial progresses.

A vendor that is proactive rather than reactive in their communication and approach to dealing with arising issues is one of the most important qualities in CRO. Challenging situations will naturally arise, and the promptness with which they are taken care of will significantly impact your clinical trial’s degree of success. Therefore, seeking a vendor that is able to match the standard of communication that you as a sponsor would like to experience throughout the duration of your partnership is one of the most critical steps in determining which CRO is the right fit for your clinical trial.

We’ve included a few additional questions pertaining to the communication structure and reporting expectations that you can ask a prospective CRO vendor to determine the degree of fit in this particular category:

Communication Expectations:

  • If we were to move forward with you, which of your team members will be our main point of contact?
  • How available will you be outside of the scheduled meetings to address any of our concerns or additional requests?
  • What will be the frequency at which update meetings will be conducted, and who will be present at those meetings?
  • Which clinical study processes will be reported on, and what will be the workflow for how we will receive this information?
  • What will be the cadence at which we will receive progress reports?
  • Would we be able to access metrics electronically via an interactive dashboard, or will you send us formal reports?

Clara Health: At Clara Health, we directly interact and actively work with several key stakeholders involved in running a clinical trial, which includes sponsors, CROs, sites, and patients. This unique position allows us to have a centralized perspective which helps us to see all the moving parts of a clinical trial at the same time, which helps to identify issues and relay this vital information and insight back to the sponsor (or other appropriate stakeholders) in the shortest time possible.

The ability to access this perspective allows us to gather the most accurate, complete, and up-to-date information about how the clinical trial is unfolding, and quickly becomes very valuable to sponsors for their clinical trial.

As an example, we may receive feedback from patients about having an unsatisfactory experience with a particular study site. We are able to aggregate and analyze this information, and relay our findings back to the sponsor and the study site to improve the experience for other patients.

4. What Is The CRO’s Client Satisfaction Record?

It is a good practice to request information or metrics from the prospective CRO vendor that can point to the degree of satisfaction of their past clients. Prior to signing the contract, vendors will naturally do their best to uplift their image and future value to you during their sales conversations with you and your team. It can be tricky to get an objective understanding of what the partnership experience will actually entail, especially when there are multiple vendors fighting for your commitment.

We recommend that you ask the prospective vendor to provide success metrics regarding areas of clinical trial operations that are going to be important for your trial.

For example, you may be interested in learning about the vendor’s relationship to finances, in which case it will be useful to ask them about situations in which they went over the planned budget, and investigate into the reasons behind that. Alternatively you may be concerned about potential delays in timelines, in which case it would be helpful to learn about metrics regarding the CRO’s ability to meet timeline expectations.

You may also request to talk to the prospective CRO’s past clients, which will help you to gain insight into what the relationship was like and give you the opportunity to examine if the way in which the particular CRO manages its relationships and performs its services meets the expectations that you would have for your potential relationship and for your clinical trial.

Clara Health: At Clara Health, our relationships with our partners and with our patients are most important to us. In the unique position where we fit in the clinical trial process, we have the opportunity to directly co-create the clinical trial patient experience with a variety of stakeholders, including sponsors, sites, CROs, and patients.

Our company’s values and culture have been directed and developed to be such that the client and patient experience is at the top of priority for all of our internal teams, and we work to provide the best quality of care to all stakeholders.

We have many testimonials from every type of partner we’ve worked with which we can happily share with you.

5. How Do You Adapt When Encountering Challenges With Running A Clinical Trial?

It is inevitable that challenges and unforeseen changes will arise throughout the operational clinical trial process, and for this reason it is important to work with a CRO vendor that can provide you with evidence of their flexibility and ability to adapt to sudden changes.

The ideal CRO partner is one that is highly consultative throughout the entire process, and has an ability and the initiative to deal with challenges at their seed stage, prior to them turning into major obstacles for the success of your trial.

CROs naturally have a large reach, and there are a lot of different clinical trial mechanisms and processes that are under their control. They are able to monitor and respond to what is going on in every key link in the chain of the clinical trial operation.

It is reasonable to expect this level of oversight from a CRO, and additional questions that can help you gain insight into this include:

  • What are some examples where the CRO was effective at monitoring the health of clinical trials they’ve helped operate in the past?
  • How quickly does the CRO respond to challenges or opportunities for improving the clinical trial experience?
  • How well does the CRO gather & process information from study sites, study teams, patients & the sponsor, and what are their typical data analysis workflows?

It is also recommended to speak to the prospective CROs past clients to help you gain insight into how well they respond and adapt to the naturally arising challenges in clinical trials.

Clara Health: While CROs do have a large reach within the clinical trial, no CRO has complete visibility into every clinical process. They are not typically set up to support full visibility, which can manifest as a potential threat to your clinical trial as it unfolds. This is especially true for parts of the clinical trial processes that CROs naturally do not specialize and often subcontract, such as clinical trial recruitment.

At Clara, we are in a unique position in relation to other key partners involved in operating the clinical trial. We are in direct and frequent contact with patients, CROs, study sites, study teams, and the sponsor, and have a very deep understanding of the patient pipeline. This allows us the unique ability to go very deep into specific parts of the recruitment chain and investigate what is working and what is not working.

In addition, Clara functions as a resource for all partners in the clinical trial. For example, we work directly with site teams to ensure that they have access to a 3rd party that they can relay their needs to and receive fast support in case there is anything they require that can improve the patient recruitment process.

6. Which Parts Of Operating The Clinical Trial Will You Be Outsourcing?

Since there are so many processes and mechanisms that go into operating a clinical trial, CROs will always outsource some parts of running and managing the study. While you can expect that the prospective CRO will subcontract some of the work, it is important to find out which exact parts the clinical study will be outsourced.

There are certain basic and key clinical processes (such as site selection) that CROs almost always help with, and if you find that these parts of your trial are going to be subcontracted to another company, it is recommended to find out why the CROs operations are set up this way and how this would impact the service you will receive.

Ultimately what matters to you as a partner and client is that the quality of service and care that you will receive will be up to standard, and meet what was promised and what you are expecting. While this trust is important after you have signed the contract, it is recommended that prior to entering into such a significant commitment that you have evidence and the conviction that the CRO of your choice is truly the right fit and will deliver the quality of service that was being discussed.

Since it is impossible to predict exactly what the quality of this relationship and services performed will actually be like in practice, it is recommended that you understand the details of what will be done for your trial and how. Investigating how the CRO outsources and subcontracts services for a clinical trial will help you to gain necessary insight that you would need to make the correct vendor selection decision.

Clara Health: At Clara, we maximize the effectiveness of the digital component across the entire digital & recruitment spectrum, which is added on top of the existing capabilities of the CROs and other vendors involved in operating your clinical trial. In addition, we offer services that augment the CROs efforts, which has the potential to significantly improve the patient experience, operations flows, recruitment and retention performance, which is so important in ensuring the success of a clinical trial.

For example, if a CRO wants to have a great site relationship, we are able to come in as a third party on behalf of the sponsor and CRO and act as a resource and additional support for sites.

In another example, If a sponsor wants to have great relationships with the patient community, Clara is able to come in on behalf of the sponsor and develop these relationships while being perceived more neutrally by the patient community.

7. Do You Have Experience Running International Trials?

If you are planning on operating an international clinical trial, it is recommended to work with a CRO that has extensive experience in this area. While many CROs will offer near-global coverage, the level of experience with specific geographic locations can significantly vary from one vendor to another.

It is important to work with a CRO that has experience running clinical trials in the specific countries and regions you are planning to conduct your research in. Being compliant with the local rules and regulations for clinical testing is a very complex process that requires existing understanding and familiarity in order to ensure logistical smoothness and to mitigate legal risks. In operating a clinical trial, there are a multitude of clinical services and processes, which can greatly vary across the many regions in which you can conduct clinical testing.

A CRO that is lacking experience in operating international trials or operating in particular regions where you plan on conducting research may not be able to meet your desired quality and agility expectations, and therefore may not be the right fit for your international clinical trial.

Clara Health: In the past, we have provided international patient recruitment and digitally-augmented trial support services for clinical trials in the EU, Canada, UK, Australia and South America.

Clara Health is fully compliant to operate international studies everywhere in the world, with the exception of Russia and China.

8. What Is Your Relationship With Patients?

Patient-centric approach to designing and operating a clinical trial is becoming more and more crucial in the clinical research space. The ability of a sponsor and their CRO partner to understand the needs and characteristics of their target patient community is a significant determinant of whether or not the study will be a success.

A sponsor that has close and authentic relationships with the patient community tends to have a deeper understanding of how to create the best clinical trial experience that will attract patients and keep their interest throughout the clinical trial.

In addition, strong relationships with patients allow sponsors and CROs to forecast recruitment and patient retention pipeline with much higher accuracy. This ability is critical for ensuring the success of the trial and mitigating the risk of low enrollment. After an understanding of the patient population is acquired, sponsors gain the necessary insight to design a clinical trial that is not only favorable to their research results, but is also practical and will result in the enrollment numbers they are looking for.

While many CROs have already recognized the importance of patient-centricity and evolved the ways in which they design and operate clinical trials, other CROs have not yet made such a pivot in their values. It is important to understand the degree of importance the prospective CRO places on creating a favorable patient experience, and what kind of infrastructure the company has to support it.

At Clara, we recommend choosing a CRO partner that is adapting to the patient-centric model which is becoming more and more important for running a successful clinical trial.

Clara Health: Since early stages of our development, we’ve had a dedicated patient advocacy team that has been integral in shaping our company’s vision and operations. We have built our entire platform and recruitment infrastructure around creating the best experience for patients. Our teams, corporate values, service offerings and company infrastructure all work in the service of the patient.

In addition, over the many years of being in business we have heavily invested in building authentic patient community relationships that span across a variety of therapeutic areas. This has given us a unique ability to receive feedback directly from patients that is genuine and authentic around marketing materials, strategy for patient recruitment, and other services that we build for specific trials.

This ability to build partnerships with the patient community in an authentic way gives us a very unique ability to engage with the patient community on behalf of a pharmaceutical company, allowing our sponsor & CRO partners the opportunity to start conversations with patients through our in-house patient advocacy team.

If you would like to learn how Clara can help you to build a strong & authentic relationship with your target patient community, get in touch with us and we’d be happy to share our capabilities and previous results with you as they relate to your current or upcoming clinical trial.

9. How Is The CRO Going To Utilize Patient Input For Developing The Trial?

In the initial stages of clinical trial design, sponsors often determine the ideal patient profiles that would help them to drive the most favorable research outcomes for their study. While it is important for the success of your trial to determine who your ideal patients are, very often these projections do not match up with what is viable in practice.

At Clara, we often encounter study protocols that are not set up realistically for successful recruitment to be possible.

Common mistakes that are made when determining trial eligibility criteria and trial design include:

  • Overestimating the interest in the clinical trial from the target patient population
  • A lack of patient focus in the trial design
  • A lack of convenience for patients in their participation
  • Complicated and/or inefficient study experience flows
  • Crafting the eligibility criteria around the patient population that is most likely to lead to favorable study outcomes, without conducting sufficient research to more accurately estimate the recruitment and retention difficulty of the group for a particular study

It is natural for there to be a “push & pull” between the research ideal and the real world practicality. It is important to determine the correct balance between these two sides for your trial, as going too far in either direction will decrease the chance of your clinical study’s success.

The nature of the industry as it is right now is such that there is excess research idealization and not enough emphasis on patient centricity. This distorted orientation has resulted in many clinical trials being unsuccessful, negatively impacting sponsors, patients and the entire clinical trials industry.

The ideal CRO partner should help you make sure that your protocol design sets your study up for success. The CRO should be able to help you determine the proper balance between the research ideal and the real world practicality, and back up their findings with sufficient research and patient data that can project your trial being a success.

Clara Health: When formulating a recruitment and retention plan for our clients, we begin with conducting thorough research into the target trial patient population. This allows us to get a clear understanding of which recruitment channels will yield the best results and what kind of marketing materials will resonate with the prospective study participants.

To ensure accuracy and real-world applicability of our research, we consult and collaborate with our internal patient advocacy and patient support teams, as well as with our clients and patients representing the target trial patient profiles. We then tie our findings back with any existing proprietary data that we have in connection with the therapeutic area or the prospective target patient group.

Our unique position within the clinical recruitment chain gives us the presence and deep-rooted access needed to effectively tap into any of the three patient traffic sources: digital recruitment, offline recruitment, or patient advocacy recruitment.

Once a recruitment campaign has gone live, we constantly monitor, analyze and optimize our performance to make sure that the processes we have in place are as efficient as possible and drive the greatest results. In addition, we have the capability to layer in any traditional advertising (such as billboard ads) if requested by the study sponsor.

9 Notable AI Companies in Clinical Research to Watch in 2023

The clinical trial is a critical stage of drug development workflow, with an estimated average success rate of about 11% for drug candidates moving from Phase 1 towards approval. Even if the drug candidate is safe and efficacious, clinical trials might fail due to the lack of financing, insufficient enrollment, or poor study design .

Artificial Intelligence (AI) is increasingly perceived as a source of opportunities to improve the operational efficiency of clinical trials and minimize clinical development costs.  Typically AI vendors offer their services and expertise in the three main areas. AI start-ups in the first area help to unlock information from disparate data sources, such as scientific papers, medical records, disease registries, and even medical claims by applying Natural Language Processing (NLP). This can support patient recruitment and stratification, site selection, and improve clinical study design and understanding of disease mechanisms. As an example, about 18 % of clinical studies fail due to insufficient recruitment, as a 2015 study reported.

Another aspect of success in clinical trials is improved patient stratification. Since trial patients are expensive - the average cost of enrolling one patient was $15,700-26,000 in 2017 -- it is important to be able to predict which patient will have greater benefit or risk from treatment. AI-driven companies operate with multiple data types, such as Electronic Health Records (EHR), omics, and imaging data to reduce population heterogeneity and increase clinical study power. Vendors could use speech biomarkers to identify neurological disease progression, imaging analyses to track treatment progression, or genetic biomarkers to identify patients with more severe symptoms.

AI is also streamlining the operational processes of clinical trials. AI vendors help to track patient health from their homes, monitor treatment response, and patient adherence to the trial procedures. By doing that AI companies decrease the risk of patient dropouts, which accounted for 30% on average.  Usually, the Phase 3 clinical study stage requires 1000-3000 participants, with a part of them taking a placebo. That’s why the development of synthetic control arms - AI models that could replace the placebo-control groups of individuals thus reducing the number of individuals required for clinical trials - might become a novel trend.

Below we summarize a list of notable AI vendors providing advanced tools for clinical development. 

ConcertAI (formerly, Concerto HealthAI) is a US-based company founded in 2017. The company provides real-world evidence (RWE) services for precision oncology. It has established the broadest clinical network through partnerships and licensing with community oncology networks, thus getting access to Electronic Medical Records, Results of NGS diagnostics, and patient-reported outcomes. Concerto then analyzes such data and generates evidence for new therapeutic approaches. In 2023, ConcertAI launched its CTO 2.0 solution to enhance the design and execution of clinical trials by leveraging expanded data assets from public sources, which include site- and physician-level trial information. Through collaborations with data partners, the system offers operational trial metrics and site profile data, emphasizing the capabilities and performance of study centers. Furthermore, the CTO 2.0 integrates social determinants of health information at the site, physician, and patient levels, aiming to automate trial site selection using a data-driven methodology. The platform's SaaS technology aligns with FDA mandates, enabling research scalability through advanced clinical informatics and data standards. The company raised a total of $300 million from a number of investors, with the latest $150 million Series C round from Sixth Street.

For decades, computing power followed Moore’s law, advancing at a predictable pace. The number of components on an integrated circuit doubled roughly every two years. In 2012, researchers coined the term Eroom’s law (Moore spelled backwards) to describe the contrasting path of drug development 1 . Over the previous 60 years, the number of drugs approved in the United States per billion dollars in R&D spending had halved every nine years. It can now take more than a billion dollars in funding and a decade of work to bring one new medication to market. Half of that time and money is spent on clinical trials, which are growing larger and more complex. And only one in seven drugs that enters phase I trials is eventually approved.

clinical research tech companies

Nature Index 2024 Health sciences

Some researchers are hoping that the fruits of Moore’s law can help to curtail Eroom’s law. Artificial intelligence (AI) has already been used to make strong inroads into the early stages of drug discovery , assisting in the search for suitable disease targets and new molecule designs. Now scientists are starting to use AI to manage clinical trials, including the tasks of writing protocols, recruiting patients and analysing data.

Reforming clinical research is “a big topic of interest in the industry”, says Lisa Moneymaker, the chief technology officer and chief product officer at Saama, a software company in Campbell, California, that uses AI to help organizations automate parts of clinical trials. “In terms of applications,” she says, “it’s like a kid in a candy store.”

Trial by design

The first step of the clinical-trials process is trial design. What dosages of drugs should be given? To how many patients? What data should be collected on them? The lab of Jimeng Sun, a computer scientist at the University of Illinois Urbana-Champaign, developed an algorithm called HINT (hierarchical interaction network) that can predict whether a trial will succeed, based on the drug molecule, target disease and patient eligibility criteria. They followed up with a system called SPOT (sequential predictive modelling of clinical trial outcome) that additionally takes into account when the trials in its training data took place and weighs more recent trials more heavily. Based on the predicted outcome, pharmaceutical companies might decide to alter a trial design, or try a different drug completely.

A company called Intelligent Medical Objects in Rosemont, Illinois, has developed SEETrials, a method for prompting OpenAI’s large language model GPT-4 to extract safety and efficacy information from the abstracts of clinical trials. This enables trial designers to quickly see how other researchers have designed trials and what the outcomes have been. The lab of Michael Snyder, a geneticist at Stanford University in California, developed a tool last year called CliniDigest that simultaneously summarizes dozens of records from ClinicalTrials.gov, the main US registry for medical trials, adding references to the unified summary. They’ve used it to summarize how clinical researchers are using wearables such as smartwatches, sleep trackers and glucose monitors to gather patient data. “I’ve had conversations with plenty of practitioners who see wearables’ potential in trials, but do not know how to use them for highest impact,” says Alexander Rosenberg Johansen, a computer-science student in Snyder’s lab. “Best practice does not exist yet, as the field is moving so fast.”

Most eligible

The most time-consuming part of a clinical trial is recruiting patients, taking up to one-third of the study length. One in five trials don’t even recruit the required number of people, and nearly all trials exceed the expected recruitment timelines. Some researchers would like to accelerate the process by relaxing some of the eligibility criteria while maintaining safety. A group at Stanford led by James Zou, a biomedical data scientist, developed a system called Trial Pathfinder that analyses a set of completed clinical trials and assesses how adjusting the criteria for participation — such as thresholds for blood pressure and lymphocyte counts — affects hazard ratios, or rates of negative incidents such as serious illness or death among patients. In one study 2 , they applied it to drug trials for a type of lung cancer. They found that adjusting the criteria as suggested by Trial Pathfinder would have doubled the number of eligible patients without increasing the hazard ratio. The study showed that the system also worked for other types of cancer and actually reduced harmful outcomes because it made sicker people — who had more to gain from the drugs — eligible for treatment.

AI can eliminate some of the guesswork and manual labour from optimizing eligibility criteria. Zou says that sometimes even teams working at the same company and studying the same disease can come up with different criteria for a trial. But now several firms, including Roche, Genentech and AstraZeneca, are using Trial Pathfinder. More recent work from Sun’s lab in Illinois has produced AutoTrial, a method for training a large language model so that a user can provide a trial description and ask it to generate an appropriate criterion range for, say, body mass index.

Once researchers have settled on eligibility criteria, they must find eligible patients. The lab of Chunhua Weng, a biomedical informatician at Columbia University in New York City (who has also worked on optimizing eligibility criteria), has developed Criteria2Query. Through a web-based interface, users can type inclusion and exclusion criteria in natural language, or enter a trial’s identification number, and the program turns the eligibility criteria into a formal database query to find matching candidates in patient databases.

Weng has also developed methods to help patients look for trials. One system, called DQueST, has two parts. The first uses Criteria2Query to extract criteria from trial descriptions. The second part generates relevant questions for patients to help narrow down their search. Another system, TrialGPT, from Sun’s lab in collaboration with the US National Institutes of Health, is a method for prompting a large language model to find appropriate trials for a patient. Given a description of a patient and clinical trial, it first decides whether the patient fits each criterion in a trial and offers an explanation. It then aggregates these assessments into a trial-level score. It does this for many trials and ranks them for the patient.

Helping researchers and patients find each other doesn’t just speed up clinical research. It also makes it more robust. Often trials unnecessarily exclude populations such as children, the elderly or people who are pregnant, but AI can find ways to include them. People with terminal cancer and those with rare diseases have an especially hard time finding trials to join. “These patients sometimes do more work than clinicians in diligently searching for trial opportunities,” Weng says. AI can help match them with relevant projects.

AI can also reduce the number of patients needed for a trial. A start-up called Unlearn in San Francisco, California, creates digital twins of patients in clinical trials. Based on an experimental patient’s data at the start of a trial, researchers can use the twin to predict how the same patient would have progressed in the control group and compare outcomes. This method typically reduces the number of control patients needed by between 20% and 50%, says Charles Fisher, Unlearn’s founder and chief executive. The company works with a number of small and large pharmaceutical companies. Fisher says digital twins benefit not only researchers, but also patients who enrol in trials, because they have a lower chance of receiving the placebo.

Patient maintenance

The hurdles in clinical trials don’t end once patients enrol. Drop-out rates are high. In one analysis of 95 clinical trials, nearly 40% of patients stopped taking the prescribed medication in the first year. In a recent review article 3 , researchers at Novartis mentioned ways that AI can help. These include using past data to predict who is most likely to drop out so that clinicians can intervene, or using AI to analyse videos of patients taking their medication to ensure that doses are not missed.

Chatbots can answer patients’ questions, whether during a study or in normal clinical practice. One study 4 took questions and answers from Reddit’s AskDocs forum and gave the questions to ChatGPT. Health-care professionals preferred ChatGPT’s answers to the doctors’ answers nearly 80% of the time. In another study 5 , researchers created a tool called ChatDoctor by fine-tuning a large language model (Meta’s LLaMA-7B) on patient-doctor dialogues and giving it real-time access to online sources. ChatDoctor could answer questions about medical information that was more recent than ChatGPT’s training data.

Putting it together

AI can help researchers manage incoming clinical-trial data. The Novartis researchers reported that it can extract data from unstructured reports, as well as annotate images or lab results, add missing data points (by predicting values in results) and identify subgroups among a population that responds uniquely to a treatment. Zou’s group at Stanford has developed PLIP, an AI-powered search engine that lets users find relevant text or images within large medical documents. Zou says they’ve been talking with pharmaceutical companies that want to use it to organize all of the data that comes in from clinical trials, including notes and pathology photos. A patient’s data might exist in different formats, scattered across different databases. Zou says they’ve also done work with insurance companies, developing a language model to extract billing codes from medical records, and that such techniques could also extract important clinical trial data from reports such as recovery outcomes, symptoms, side effects and adverse incidents.

To collect data for a trial, researchers sometimes have to produce more than 50 case report forms. A company in China called Taimei Technology is using AI to generate these automatically based on a trial’s protocol.

Increased trial complexity

The cost of drug development continues to rise, and the size and complexity of clinical trials is a major factor. In the past two decades, the number of countries in which a clinical trial is conducted has more than doubled, and the average number of data points collected has grown dramatically. There are more endpoints — outcomes of a clinical trial that help to determine the efficacy and safety of an experimental therapy — and procedures to measure these outcomes, such as blood tests and heart-activity assessments. By comparison, eligibility criteria for participants, which include demographics such as age and sex and whether a participant is a healthy or a patient volunteer, have remained relatively consistent.

A few companies are developing platforms that integrate many of these AI approaches into one system. Xiaoyan Wang, who heads the life-science department at Intelligent Medical Objects, co-developed AutoCriteria, a method for prompting a large language model to extract eligibility requirements from clinical trial descriptions and format them into a table. This informs other AI modules in their software suite, such as those that find ideal trial sites, optimize eligibility criteria and predict trial outcomes. Soon, Wang says, the company will offer ChatTrial, a chatbot that lets researchers ask about trials in the system’s database, or what would happen if a hypothetical trial were adjusted in a certain way.

The company also helps pharmaceutical firms to prepare clinical-trial reports for submission to the US Food and Drug Administration (FDA), the organization that gives final approval for a drug’s use in the United States. What the company calls its Intelligent Systematic Literature Review extracts data from comparison trials. Another tool searches social media for what people are saying about diseases and drugs in order to demonstrate unmet needs in communities, especially those that feel underserved. Researchers can add this information to reports.

Zifeng Wang, a student in Sun’s lab, in Illinois, says he’s raising money with Sun and another co-founder, Benjamin Danek, for a start-up called Keiji AI. A product called TrialMind will offer a chatbot to answer questions about trial design, similar to Xiaoyan Wang’s. It will do things that might normally require a team of data scientists, such as write code to analyse data or produce visualizations. “There are a lot of opportunities” for AI in clinical trials, he says, “especially with the recent rise of larger language models.”

At the start of the pandemic, Saama worked with Pfizer on its COVID-19 vaccine trial. Using Saama’s AI-enabled technology, SDQ, they ‘cleaned’ data from more than 30,000 patients in a short time span. “It was the perfect use case to really push forward what AI could bring to the space,” Moneymaker says. The tool flags anomalous or duplicate data, using several kinds of machine-learning approaches. Whereas experts might need two months to manually discover any issues with a data set, such software can do it in less than two days.

Other tools developed by Saama can predict when trials will hit certain milestones or lower drop-out rates by predicting which patients will need a nudge. Its tools can also combine all the data from a patient — such as lab tests, stats from wearable devices and notes — to assess outcomes. “The complexity of the picture of an individual patient has become so huge that it’s really not possible to analyse by hand anymore,” Moneymaker says.

Xiaoyan Wang notes that there are several ethical and practical challenges to AI’s deployment in clinical trials. AI models can be biased . Their results can be hard to reproduce . They require large amounts of training data, which could violate patient privacy or create security risks. Researchers might become too dependent on AI. Algorithms can be too complex to understand. “This lack of transparency can be problematic in clinical trials, where understanding how decisions are made is crucial for trust and validation,” she says. A recent review article 6 in the International Journal of Surgery states that using AI systems in clinical trials “can’t take into account human faculties like common sense, intuition and medical training”.

Moneymaker says the processes for designing and running clinical trials have often been slow to change, but adds that the FDA has relaxed some of its regulations in the past few years, leading to “a spike of innovation”: decentralized trials and remote monitoring have increased as a result of the pandemic, opening the door for new types of data. That has coincided with an explosion of generative-AI capabilities . “I think we have not even scratched the surface of where generative-AI applicability is going to take us,” she says. “There are problems we couldn’t solve three months ago that we can solve now.”

How artificial intelligence can power clinical development

Clinical development and the randomized clinical trial (RCT) remain largely unaffected by the unprecedented wave of innovation in pharmaceutical R&D fueled by developments in artificial intelligence (AI), including generative AI (gen AI) and foundational models. However, they are under pressure from the rise of precision medicine and a more competitive development landscape. So far, the adoption of AI for clinical development has emphasized operational excellence and acceleration, but advances in scientific AI have made this the time to leverage modern analytical tools and novel sources of data to design more precise, efficient trials with greater success rates.

About the authors

This article is a collaborative effort by Chris Anagnostopoulos, David Champagne , Thomas Devenyns, Alex Devereson , and Heikki Tarkkila, representing views from McKinsey’s Life Sciences Practice.

The introduction of RCTs in the mid-20th century ushered in the modern era of evidence-based drug development. Their rigidity and simplicity were welcome defenses against an overreliance on anecdotes and case studies and have unarguably served patients well, supporting the introduction of countless safe, effective therapies. Yet RCTs are starting to be seen as bottlenecks that lengthen the time for therapies to gain approval and can increase costs. 1 Donald A Berry, “The brave new world of clinical cancer research: Adaptive biomarker-driven trials integrating clinical practice with clinical research,” Molecular Oncology , 2015, Volume 9, Issue 5; Michael Baumann et al., “How much does it cost to research and develop a new drug? A systematic review and assessment,” PharmacoEconomics , 2021, Volume 39, Issue 11. Meanwhile, as gen AI breaks milestone after milestone, patients eagerly await the translation of such unprecedented technological progress into pharmaceutical R&D that could deliver faster access to better treatments.

In addition to rising expectations about timelines, clinical development is also facing increasing demands to generate targeted and meaningful data. As precision medicine becomes mainstream, RCTs often must prove not only the general efficacy of a treatment but also whether it will benefit a specific segment of the patient population. The smaller that segment, the harder it can be to enroll enough patients in trials. In addition, the bar for what constitutes a clinically meaningful treatment effect is creeping higher to meet standards set by regulators and payers as well as competitive pressure. In most therapeutic areas today, there are, on average, 40 percent more assets per indication than in 2006, 2 McKinsey research on data from EvaluatePharma, March 2019. raising the need for greater differentiation. And clinicians and patients alike need more evidence to make decisions about the best available treatment at a given time.

All this comes as researchers accelerate drug discovery by making greater use of AI and gen AI, such as DeepMind’s AI-enabled platform AlphaFold, which can predict the 3-D structure of molecules 3 “ AI in biopharma research: A time to focus and scale ,” McKinsey, October 10, 2022. leading to a pipeline of more and better-designed preclinical assets with a better target validation. Companies are also striving to improve their operational processes with a view to speeding up the time it takes to apply for a first-in-human study. But if clinical development fails to keep pace, the benefits to patients of faster drug discovery will inevitably be delayed, and delivering on the promise of AI-enabled acceleration may flounder.

While the RCT will remain a central pillar of clinical development, the tide is changing. Regulators have recently issued guidance on appropriate use of real-world data (RWD). 4 See, for example, the US Food and Drug Administration’s real-world evidence activities responding to the 21st Century Cures Act. The healthcare data ecosystem is booming, leveraging privacy-respecting technology to make patient-level data safely available for research. And evidence generation from multiple data sources is now possible using causal machine learning, which aims to distinguish correlation from causation via a combination of biostatistics with machine learning (ML) and, increasingly, gen AI and foundational models.

Despite this level of promise, only a handful of established companies are deploying AI and data-driven approaches systematically in their clinical development. The focus so far has been on improving operational excellence and increasing acceleration rather than helping to inform trial design strategy. The remainder of this white paper dives deeper into the context, gives tangible example use cases and associated impact, and identifies challenges companies face when adopting AI for clinical development. Rather than staying at a high level, it aims to bring the topic to life through relevant details and case examples.

Never just tech

Creating value beyond the hype

Let’s deliver on the promise of technology from strategy to scale.

Expanding adoption of AI and RWD for clinical development

Today AI can draw upon growing volumes of RWD. Electronic health records and claims data from certain geographies are widely available, and novel data sources—including biobanks, data omics panels, population-wide genomic studies, patient registries, and imaging and digital pathology—are increasing in number and diversity. All these sources reflect a notable change in patients’ ability to share their data for the purpose of advancing research and treatments in privacy-respecting ways, including technology that enables the training of ML models in a manner that respects patients’ privacy.

In addition, new tools can systematically capture knowledge from unstructured data. Large language models (for example, BioGPT) are able to convert unstructured physician notes into high-quality structured data. Similarly, these models can search the vast corpus of published literature and identify connections between biological entities on a large scale, generating high-quality input for knowledge graphs that better represent the totality of available evidence on a given indication across domains, including genes, targets, proteins, pathways, and phenotypes.

Most pharma companies using AI and RWD in clinical development tend to do so only in isolated use cases, and they rarely deploy both in combination. For example, they might use machine learning to select trial sites or to predict patient enrollment rates. They might use RWD to measure disease prevalence—the size of an eligible population—to understand the natural course of a disease among untreated patients, or to construct an external control arm for regulatory purposes. While these use cases deliver value, a great deal more is now possible. Similarly, while the level of funding and investment going into AI-enabled drug discovery companies has tripled in the last five years, that same trend is not true for equivalent companies in the clinical development space.

Four use cases that demonstrate the potential of AI

Companies that are deploying AI combined with RWD are seeing impactful results. While RWD can be valuable supporting evidence in health authority submission packages, the most successful companies focus their use of AI and RWD to make better and more informed decisions to support the success of clinical development programs in every step, from asset and portfolio strategy to protocol and trial design:

  • At the stage of defining an asset strategy, AI and RWD can reveal which indications are most promising indications to pursue for novel assets. Several leading biopharma companies identified multiple new indications for existing assets in this way, and an early-stage biotech used AI and RWD to assess whether to shift its indication selection strategy regarding a novel asset.
  • AI and RWD can support decisions about the target patient population of a clinical trial, with subgroup discovery, refine trial eligibility criteria and help remove patients that are highly unlikely to benefit from the treatment, and shorten the length of trials. One early-stage biotech could better characterize “super-progressors” (that is, patients whose disease was likely to progress faster within the time frame of a clinical trial) and design a trial with similar expected benefits in a faster time frame.
  • For decisions about portfolio strategy, AI and RWD can help companies identify the right combination of drugs for an indication or for the right patients. One biopharma company leveraged a prospective observational data set to generate evidence supportive of earlier positioning of its third-line treatment. Another was able to identify “super-responders” for several drugs in its portfolio—insights that helped the company position its assets optimally in a crowded indication.
  • At the step of selecting and optimizing the end points of a clinical trial, AI and RWD can help a company identify patient attributes that closely track the primary end point over time. One biopharma company replaced a rare disease’s existing end point, which was an infrequent event, with end points that occurred with greater frequency or could be measured with blood tests. This cut the length of trials by 15 to 30 percent.

The following discussion looks in greater depth at four detailed use cases, illustrating the wealth of information that AI can unlock.

Indication selection for asset strategy

Selecting which indications to target with a specific molecule is one of the most important decisions a biopharma company makes. This decision is often informed by a combination of input from key opinion leaders, literature reviews, omics analysis (for example, genome-wide association studies), RCT data, and competitor decisions. Such decisions rarely are fully data driven, typically prove hard to integrate, and cover only part of the available evidence base, resulting in a subjective and suboptimal synthesis. In contrast, strategies informed by RWD and AI are objective and comprehensive in their use of multiple data sets and foundational models built on clinical data continually redefining the art of the possible.

For already-approved therapies, companies can use RWD to understand the therapies’ likely efficacy on alternative indications. One approach is examining the outcomes of patients who were prescribed the drug on a spontaneous basis by their physician; another is determining a drug’s average effect on patients exposed to the treatment because of incidental comorbidities. AI techniques can then extrapolate any findings to a set of patients whose characteristics may be distributed differently, by leveraging observed correlations between patient characteristics and outcomes.

Where companies are looking to expand the indication of an approved asset or identify for a novel asset, RWD and AI can estimate the biological proximity of one indication to another from a patient and clinical perspective—that is, whether the patient experiences similar symptoms, comorbidities, lab characteristics, and treatment journeys. Foundational models that treat medical events as words and patient medical histories as documents can uncover the semantic similarity of different events, including diagnoses. Each indication, from what is likely to be a sizable list of those with biological proximity, is scored according to its similarity to one or more anchor references—perhaps the indication for which the asset was originally approved or, in the case of a novel asset, one for which there is strong preclinical evidence of efficacy of the asset’s mechanism of action (MoA).

The scoring can also incorporate information from molecular knowledge graphs that show new connections—for example, between entities such as proteins or human biological pathways that have already been identified in literature or public data. Exhibit 1 shows a potential outcome of this approach: it can reveal the indications most strongly connected to each of the reference indications, serving as an anchor into the existing evidence base. The indications with the most connections to these references are further prioritized by unmet medical need, strategic fit, and technical feasibility, resulting in an evidence-based indication selection.

These analytical approaches can identify novel indications that can be rapidly validated via in vitro or animal models, can increase the confidence in selecting indications with a high probability of success, and can derisk resource allocation accordingly. The analysis provides a clearer and more holistic evidence base for investors, shareholders, and R&D leaders, and it can reduce the opportunity cost of blind alleys by helping new treatments reach patients faster.

Subgroup discovery for trial design

Once an asset has been matched with an indication, pharmaceutical companies pursue an all-comer clinical development and trial design strategy—that is, one that includes all patients except those deemed high-risk based on input from key opinion leaders and conventional wisdom. 5 The use of the all-comer strategy may reflect a low level of confidence in existing hypotheses that currently seek to explain response heterogeneity in patient subpopulations. As a result, patients unlikely to respond to a treatment may be included in the trial. A notable exception to this method is in precision oncology, where researchers use specific biomarkers discovered preclinically (such as genetic mutations) to stratify patients according to their probability of progression or to predict a patient’s response to different treatments. This approach is revolutionizing oncology treatments, but even it can identify only a fraction of possible patient subpopulations.

In contrast, AI and omics-rich RWD can examine thousands of genetic and/or phenotypic attributes to pinpoint the combinations most likely to influence prognostic or predictive scores, explain response heterogeneity, and improve a trial’s technical probability of success. Even in situations where the patient cohorts are modestly sized, foundational models trained on broad RWD can be used as a starting point for more bespoke modeling at the indication level.

One large biopharmaceutical company used RWD to remove likely nonresponders from a trial and to reduce its expected duration by between 5 and 10 percent without compromising its probability of success, which would allow the treatment to reach patients faster. Another company leveraged hospital episode RWD to identify super-responders to its comparator arm for an asset in Phase I, ensuring the trial was designed in a manner that focused on patients without access to effective treatments.

AI for subgroup discovery can also directly support the strategic trade-off between the size of the eligible population and the level of the treatment effect in a smaller population, in the form of an efficient frontier (Exhibit 2). The different subpopulations that are marked as blue on the exhibit are those for which it is impossible to simultaneously increase their breadth without reducing the drug’s expected effect. This approach widens the overlap between patients with access to this new treatment and patients who are most likely to benefit significantly from it.

Subgroup discovery and comparative efficacy for portfolio optimization

Not only can AI be used to discover subgroups to inform the design of a trial, it also can contribute to the wider portfolio strategy. The product pipelines and portfolios of many biopharmaceutical companies contain multiple assets aimed to treat a similar set of patients, often because companies lack sufficient evidence to inform the portfolio strategy differently, especially for new MoAs. However, the systematic analysis of all available data sources can predict the response of different patient subgroups (or disease endotypes), which could help companies hone their portfolio strategy—in some cases, resulting in a double-digit percentage improvement in net present value. This strategic stance can support targeted trials that produce the type of precision evidence that clinicians need to make the best possible treatment decisions for their patients amid a proliferation of novel assets.

In addition, several analytical approaches and data sources can be combined to determine the efficacy of novel MoAs in the portfolio relative to each other or to approved treatments of different patient subgroups. Enriching RWD with data from molecular knowledge graphs can enable foundational-model-powered representations of treatments that represent their associated biological pathways. From this, the company can estimate the efficacy of a novel treatment by observing the outcomes of approved treatments that share similar biological action mechanisms with the novel treatment. This exercise can be repeated across multiple disease endotypes or patient subgroups, identified through a combination of patient-level attributes (Exhibit 3).

End point optimization in clinical development

In many trials, there is no single, established end point. In others, it can be hard to know which of several would best measure the intended action of the drug. Some end points may take a long time to manifest, leading to extended development timelines. Others may detect progression that is more reliable for some types of patients than for others or that may be particularly invasive, increasing the trial’s burden on patients.

AI used on rich, patient-level longitudinal data sets can be deployed to identify patient attributes that closely track the primary end point over time. Such an application can control multiple confounding factors to ensure the association persists in future trials where the patient population may differ, thereby establishing potential novel end points.

Here, X-rays, CT and MRI scans, and other imaging techniques are often valuable sources of data for monitoring biomarkers in a noninvasive manner (as is the case with using MRIs to help detect Alzheimer’s disease 6 Ruth Stephen et al., “Change in CAIDE dementia risk score and neuroimaging biomarkers during a 2-year multidomain lifestyle randomized controlled trial: Results of a post-hoc subgroup analysis,” Journals of Gerontology: Series A , 2021, Volume 76, Issue 8. ). Foundational models using medical imaging are increasingly able to extract imaging biomarkers curated by human expertise from raw images at scale. They can even discover altogether novel, deeply hidden visual signatures of disease activity and severity with better predictive characteristics.

In all cases, the association between novel end points and desired patient outcomes such as survival or quality of life must persist even under treatment. The clinical data and the information present in RWD must be combined with a biological understanding of the mechanisms affected by the considered treatment.

Tackling the organizational challenges

Inevitably, supplementing a century-long, RCT-dependent approach to clinical development with a new, analytics-driven one using novel data poses organizational challenges. Here are some ways to tackle them.

Embed AI into clinical development

The governance processes and incentive structures in place in most biopharmaceutical companies encourage default solutions in clinical development at the asset team level and beyond. One consequence is the prevalence of all-comer trials, which target the broadest possible population without leveraging evidence about nonresponders and super-responders—a method that can increase trials’ duration and decrease their probability of success, resulting in longer waits for patients who would benefit from the treatment.

R&D leaders can help change that culture by encouraging the use of analytical methods to integrate all sources of available evidence when making key decisions. Individual incentives can help. A stronger step is to strengthen the development governance model to require that all key decisions be supported by AI.

Develop internal capabilities and talent

External providers can supply off-the-shelf AI solutions to support some use cases. But with so many new solutions emerging, no provider can yet support them all. Even if they could, companies would be unwise to become dependent upon them for critical strategic decisions. Providers with such rich intellectual property might eventually become competitors.

Biopharmaceutical companies could therefore consider building their own AI capabilities and products. However, significant investment is needed to acquire the relevant data sets; build up the necessary data science, data engineering, and business translator expertise; and establish agile product development processes that ensure use cases deliver business value in a timely and cost-efficient manner.

Companies will also have to work hard to attract and retain top data scientists and data engineers, as the biopharmaceutical industry is not typically their first choice. Measures that can help include offering competitive remuneration packages, building an innovative employer brand, and locating in key talent hubs. So, too, can a focus on the industry’s value proposition—offering employees the chance to help people lead longer and healthier lives.

Develop a targeted data strategy

With so much data becoming available, companies should consider formulating a detailed and iterative data strategy for each disease area. The purchase of certain commercial data sets, such as electronic health records, claims, and sometimes omics, can be relatively straightforward, even in therapeutic areas such as oncology, where biomarker-rich data are required. But other types of data sets—registries, biobanks, and clinical trials from other pharma companies—can involve complex negotiations and contracts, and companies will have to partner with a range of different data providers.

In addition, each data set is likely to be structured differently, with varying levels of quality and completeness. This means companies will likely need data curation and analytical capabilities for tasks such as combining different data sets to plug gaps in evidence and meeting regulatory expectations for the use of real-world data.

Build scalable products

AI’s power lies in its application across the clinical development portfolio, not restricted to isolated use cases. Achieving this kind of scale can be hard, due to limitations of the code base, data platforms, the company’s data engineering capabilities, and the analytical stack needed to collect, combine, and analyze data. As a result, pilots often remain just that—never reused or deployed against other assets in development.

To counter this, analytical use cases should be built as products, meaning solutions built in a manner that makes them easy to reuse and scale for different use cases, even at the proof-of-concept phase. The code base should be well annotated, for example, and deploy common, reusable analytical components that are either developed internally, open-source, or bought off the shelf. Shared ML development standards and coding frameworks can help by speeding up development work across different use cases because data scientists and engineers are familiar with them. Companies also need a mature and flexible ML operations stack—that is, the operational components needed to streamline the process of taking ML models to production and maintaining and monitoring them.

By harnessing novel data and the power of AI, biopharmaceutical companies can move beyond RCTs to vastly improve clinical development. The benefits accrue at each stage of the development process, from formulating asset strategy to designing the protocol and trial planning. For patients, the results can speed up access to new treatments, thanks to an accelerated development timeline, and make treatments more likely to elicit the strongest response.

High-impact solutions are already being implemented, and more will follow. Companies can benefit from beginning to build the capabilities they need and scaling them across the portfolio and their assets’ life cycles. The clinical development and trial design system is ripe for change, and the value to patients will be vast.
