19.1 Introduction
Over the past two decades, the use of digital technology in clinical trials has proliferated, a shift that has been argued to reach a more diverse and representative trial population more efficiently. Also known as decentralized clinical trials, digital clinical trials (DCTs) saw a vastly increased use amid the COVID-19 pandemic, when remote methods were employed to reach trial participants who could not reach trial sites in person. While improving clinical trial accessibility through decentralized approaches is important, it is also crucial who is leading these efforts in the generation of scientific evidence. This essay re-centers the relationship between private equity (PE) and clinical trials in the analysis of DCTs and the social value of access in the for-profit, private production of scientific evidence. In a highly fragmented biotechnology industry, where PE firms are increasingly acquiring small firms that provide outsourced clinical research services, DCTs and PE firm unions might bring about additional opportunities to increase drug data opacity, compromising the access to the greater production of scientific evidence driving digital technology.
Structured in three parts, the essay examines the current state of DCTs and questions whether PE firms’ investment in DCTs is convenient for data generation and access to quality medicine. The first section discusses the exponential growth of DCTs, particularly in the years following the pandemic, and their potential to address challenges of the traditional on-site clinical trial model. The second section examines PE firms’ increasing interest in DCTs from a business, law, and policy perspective. The final section discusses the risks of generating scientific evidence through profit-driven models, with a special focus on the issues of publicity in the wider political economy of PE-funded medical research.
19.2 From In-Person to Remote Clinical Trials
Clinical trials are essential for generating the scientific evidence that regulators require to permit and ensure only safe and effective health care innovations leave the laboratory bench and eventually reach the market. In the past decade, private actors, including PE firms, have invested and managed the evidence production endeavor, critical to innovation access. Meeting the appropriate trial enrollment levels has been an important dimension of generating relevant and sufficient trial data that can be used to evaluate the efficacy and safety of medical treatments, drugs, and devices.Footnote 1 Yet, finding and recruiting trial participants can often be an operationally limiting and expensive task.
Traditionally, patients had to attend medical research sites in order to participate in clinical trials. This presented a series of problems to researchers. Consider that more than 70 percent of the US population lives at least two hours away from an academic medical research center and that only 50 percent of the US population participates in clinical research.Footnote 2 Bringing patients to a facility reduces generalizabilityFootnote 3 and generally implies mobility constraints that could make trial participation expensive or impossible.Footnote 4 These difficulties, in addition to participants’ communication and the identification of operational constraints, tended to increase the participants’ burden, considerably extending trial timelines and inflating costs, particularly in trials involving a large number of participants.Footnote 5
Diversity in trial patient pools is another problem affecting clinical data generation. A recent study of sixty-four trials that led to fifty-nine FDA-approved cancer therapeutics between January 2012 and December 2017 showed an adequate representation of women (56 percent), older adults (24 percent), and racially and ethnically minoritized patients (16 percent).Footnote 6 If evidence for new medical interventions is “dominated by data from unrepresentative populations,” as independent researchers argue, different disease severities, comorbidities, age groups, geographies, and other profiling factors will be excluded and users harmed by disparate access to medical treatment.Footnote 7
The decentralization of trials has thus been presented as a way to deal with recruitment and demographic representation obstacles while significantly reducing associated costs and time. Trials conducted entirely virtually can reach a larger, diverse population and their participants no longer need to travel to medical research centers and might not even meet with their study teams.Footnote 8 Remote monitoring and real-time oversight of participants can alleviate investigators’ and participants’ workloads while increasing the opportunities for assessments over extended periods of time.Footnote 9 This is expected to accelerate scientific evidence generation, with higher and faster data accuracy and cost controls, and, potentially, contribute to catapulting more products to the market sooner. Technology adds to decentralization improved recruitment, oversight, and the retention of a larger and diverse trial participant pool, data collection and aggregation, and data analytics. Huge growing trial data volumes will progressively be subject to sophisticated analytics and data-driven algorithms, with Artificial Intelligence and Machine Learning in clinical research reshaping drug development.Footnote 10
Although running medical research studies remotely with the assistance of technology has been an ongoing practice for years now,Footnote 11 and even captured the attention of the government,Footnote 12 it was only by the end of the past decade, with the COVID-19 pandemic, that their decentralization and the use of research digital tools gained popularity. As a result of isolation-based public health measures for the risks of contracting the virus and clinical networks’ priorities shifting from research to the treatment of COVID-19 patients, trial enrollment decreased by more than two-thirds across all therapeutic areas.Footnote 13 Remote trials proliferated and the Food and Drug Administration (FDA) required research sites to adjust their safety procedures or switch to digital, waiving Institutional Review Boards (IRB) or FDA approval but still subjecting them to reporting.Footnote 14 Remote trials during the pandemic helped to assess the strengths and weaknesses of virtual trials – for example, that studying patients remotely can be safe as long as participants do not have a serious medical condition (e.g., infectious disease or progressive cancer)Footnote 15 – and became a regular practice.Footnote 16 Since 2021, DCTs have become a “major part of [the industry’s] portfolios.”Footnote 17 Several clinical research organizations (CROs)Footnote 18 and academic research and related public–private initiativesFootnote 19 have developed products across the decentralized trial spectrum.
19.3 Private Equity’s Interest in DCTs
The US health care industry has been increasingly attractive to PE firms for some time now.Footnote 20 Distinctively, the United States reports an average of 2.3 PE health care transactions daily.Footnote 21 From hospital and nursing home buyouts in the 2000s, to medical practice acquisitions such as radiology and outpatient care, including urgent care and ambulatory surgery centers and neonatal and trauma units in the 2010s, PE health care investments have increased twenty times their value in the past two decades.Footnote 22 PE has also been active in nonhospital-based dermatology, dental, orthopedics, and behavioral health specialties,Footnote 23 and medical debt collecting.Footnote 24
Clinical trials, particularly those remote and digital, represent a new business opportunity for PE firms: If a drug can reach the market sooner and at a lower cost, manufacturers will make more profit. By outsourcing the performance of trials to CROs, manufacturers can reduce investment risks and separate the operational costs of running a trial; in turn, CROs can make revenues despite trials failing or if a drug is not approved.Footnote 25 The way in which PE firms operate, raising capital and investing it into various privately held companies, often grants them ownership or enough of a stake to gain operational control of their portfolio’s companies, appoint company directors, and dictate every aspect of the companies’ business and affairs.Footnote 26 The decentralization and digitization of trials require infrastructure outside of a research institution and technology tools that are often proprietary. This provides CROs – and the PE firms that finance and manage them – with more opportunity to grow, continue penetrating the space of trials, and build the infrastructure and technology required. Studies found substantial value in employing DCT methods in phase II and phase III of clinical trials, with high returns on investments.Footnote 27 Decentralization would be particularly more amenable for “general population drugs,” which serve a category of patients with less hospital-based resourcing needs;Footnote 28 yet, the industry has expressed interest in the decentralization of trials for rare diseases, too.Footnote 29
Financial stability would make trials a reliable investment for PE portfolios. Business strategies vary somewhat by type of private equity investment, but prioritizing short-term, high profits stays as a primary goal.Footnote 30 Unlike other technology-based industries, trial demand is resilient to inflation and economic declines. Research and development (R&D) of new health technologies can largely be government-backed, which secures low debt levels once entering clinical trial phases. Although these are signs of stable cash flow, some high volatility suggests clinical trials to be risky investments, with already cautionary tales of valuation fluctuation and labor struggles.Footnote 31 Science 37, one of the first DCT startups, showed continued and massive share price drops after an oversubscribed offering in 2020 and a major public listing in 2021.Footnote 32 Nevertheless, overall, DCTs make financial sense to PE firms that tolerate volatility and can make huge returns provided timely, good planning.Footnote 33 The clinical trial space is attractive for businesses; valued at US$16 billion, with an estimated 6.8 percent compound annual growth rate through 2025.Footnote 34 Since January 2021, ten PE-backed trial platforms have been acquired or created,Footnote 35 yet mostly interested in late-stage trials.Footnote 36 No drug studied via remote trials (whether PE funded or not) has been approved yet to date.
From a legal and policy perspective, the outsourcing of pharmaceutical services has not spurred enough regulatory oversight. Generally, PE firms’ transactions are not subject to rigorous scrutiny even though they can have large effects on competition.Footnote 37 About 90 percent of PE transactions – either buyouts or investments – are exempt from the federal mandatory antitrust reporting threshold,Footnote 38 with the exception of a few states, such as Oregon and Massachusetts, that monitor health care antitrust activity.Footnote 39
Fragmentation also makes clinical trials a prime target for PE firms. The medical research market includes stand-alone clinics and physician practices performing studies on a part-time basis, commercial sponsors, and CROs. As fragmented as trial activities thus become, it is harder for policies to address trial challenges with specificity, which creates the risk of ignoring the secondary effects of a given policy choice and moving toward contradictory policy goals – like expanding DCTs through PE firms.Footnote 40 For PE firms, fragmentation also represents the opportunity to consolidate markets and reduce operational costs, which PE firms do to maximize profits.Footnote 41 Vertical integration of CROs’ service offerings (e.g., recruitment, data collection) allows PE firms to gain operational control over trials.Footnote 42 As PE firms acquire independent sites, they become part of larger networks to be sold off once they are rolled up into a business.Footnote 43 Following a merger, acquirers tend to prioritize services that are operationally cost-efficient. Recruitment might be one of them. Additionally, former CEOs of pharmaceutical companies are occupying influential seats at PE firms,Footnote 44 suggesting new combinations of small and big pharmaceutical industry dominance that will demand new private law tools to ensure that consolidations receive increased scrutiny.
19.4 Greater Scientific Evidence at the Risk of More Opacity
Allegedly, PE firms have targeted DCTs as a blooming business opportunity.Footnote 45 At least 65 percent of the total clinical research transactions reported until February of 2023 have involved PE firms.Footnote 46 Eleven of the twenty-five PE firms identified by PitchBook as health care sector top investors have bought stakes in CROs.Footnote 47 Is it beneficial for scientific evidence production that PE firms finance and manage clinical trials, their decentralization, and digitization?
This essay frames this question not as one of ownership but of governance, motivated by concerns around access to scientific evidence produced by private sector actors. PE firms’ interest in DCTs is in tension with the original sponsor role of the industry. The FDA first coined the term drug “sponsor” in the 1960s to differentiate research tasks from development, when the labor of clinical investigations was conceived divorced from the industry. The role of drug manufacturers was to promote the merits of a novel product to the regulatory agency until it reached approval for commercialization.Footnote 48 The Bayh-Dole Act of 198049 opened the door for financialized actors to venture into drug development.Footnote 49 In the 1980s and 1990s, pharmaceutical firms underwent a corporate strategy transformation under the rise of the idea of shareholder value maximization (SVM), which distorted the way in which larger, publicly traded pharmaceutical companies generate growth for their shareholders – not on their current profitability but on their potential to deliver future earnings.Footnote 50 Although the expansion of financial actors, like venture capital, in the US health care systemFootnote 51 and biotechnology particularly is not new,Footnote 52 as PE firms get more involved in the decentralization and digitization of research, the industry’s original sponsor role reaches – yet again – new extremes. It also reinforces the supply-driven approach that has shaped biopharmaceutical innovation, which aligns biopharmaceutical innovation priorities with market demand over the social value of science, leaving the end goal of access to scientific evidence and resulting medicine at the periphery.Footnote 53
Scholars have raised concerns about PE firms’ investment in health care based on negative outcomes in the delivery of medical care: decline in safety and efficacyFootnote 54 and higher prices.Footnote 55 Clinical trials bring forth their own set of risks, too. Two areas of concern are the ethics of trial participants’ engagement (including data privacy protections, inclusivity, and participants’ rights and safety)Footnote 56 and the opportunities to skew or produce faulty data in uncontrolled environments.Footnote 57 In these cases, private law tools like torts are available to enforce data privacy obligations. But having new financialized actors like PE firms, private by nature, directly involved in a considerable and rising number of trials that generate critical scientific evidence that supports the release of new health technologies into the market, might affect all and everyone as potential science users, beyond trial participants, and subject to less transparency regulations.
Crucially, DCTs are expected to generate greater data volume and data diversity. As PE firms engage in ambitious DCTs, they will gain access to a larger number of patient data sources, leverage data management tactics with sophisticated digital tools, and be able to obtain more critical clinical data. For instance, a 2021 Tuft CSDD report evidenced that phase III clinical trials already generated an average of 3.6 million data points, three times the data collected by late-stage trials ten years ago.Footnote 58 These numbers are expected to continue to grow as trials are digitized. Now, more data has not always led to better scientific evidence for quality drugs. The clinical evidence that the industry currently produces and delivers to the FDA in order to assess the safety and efficacy of drugs is either incomplete or not as transparent and accessible as needed. There is no indication that PE firms’ involvement in the generation of scientific evidence will fix the information problem clinical trials face – to the contrary, the risk of opacity may even increase under PE leadership due to their opportunistic business model.
PE firms generate scientific evidence that is essential for regulators to exercise oversight over drug development, improve treatment guidelines, incentivize better innovation, and shed light on and correct bad industry practices. Data publicity is also important to bioethicists, who aim to reduce risks to trial participants and drug users; to health economists, to better direct health care spending to safe and effective treatments; and to independent researchers, advocates, and citizens at large for data reevaluation and accountability.Footnote 59 The FDA, which “houses the largest known repository of clinical data” in the world,Footnote 60 plays a gatekeeping role, with a primary function of information generation and validation.Footnote 61 This function is essentially frustrated when all information about drugs obtained in clinical trials is not made available or a part of it remains secret. All information includes both the positive and the negative data generated at trials. The burden to provide evidence of any negative effects is on firms.Footnote 62 However, drug developers have insufficient incentives to generate and share negative information as they want drugs to be approved, affecting validation.Footnote 63 A free rider problem leads to an information production and data publicity problem that PE firms could hardly overcome due to their appetite for maximizing profits in line with their fiduciary duty to create value for their investors in return for their entrusted money. This transactional PE–investor relationship silences other stakeholders’ interests (e.g., developing science for the benefit of the community) and makes more socially oriented goals, such as making complete drug evidence accessible, be perceived with disbelief.Footnote 64
Different trials produce different types of data. Metadata is essential for interpreting clinical trial results.Footnote 65 They include the study protocols that set forth investigators’ statistical analysis plans and the endpoints a clinical study will evaluate. The FDA requires metadata for drug assessment and approval;Footnote 66 independent researchers use them to run a reanalysis of studies and identify probable misleading studies generating flattering results.Footnote 67 Summary data include clinical trial summaries, prepared by manufacturers and submitted to the FDA, that highlight key trial results. Although not routinely disclosed by the FDA, summary data can jeopardize medicines’ permanence in markets.Footnote 68 Another set of valuable data for reanalysis is individual patient-level data. On a voluntary basis, raw and granular data collected per trial participant is made available in analyzable form and used to identify discrepancies, for example, in summary data.Footnote 69 A drug is safe only if its known therapeutic benefits outweigh its known risks;Footnote 70 thus, because “safety can only be understood in relation to efficacy and vice versa,”Footnote 71 and the safety and efficacy of drugs must be determined together, it is absolutely necessary that all trial data – metadata, summary data, individual patient-level data, and others – are not omitted, but disclosed and shared. The hidden data and existing opacity practices over privately produced evidence have already translated into grave examples of unsafe medicine. Vioxx led to tens of thousands of cardiac deaths,Footnote 72 whereas Paroxetine (Paxil) caused suicidal thoughts in a substantial portion of young patients who used the antidepressant during pediatric treatment, despite studies showing their risks clearly.Footnote 73
PE firms’ profit incentive schemes continue to put the prioritization of safety maximization at risk. The absence of PE-backed trials and approved drugs to date makes it hard to run a comparative analysis between trials with and without PE support. During the pandemic, the New York-based private equity firm Headlands Research established in 2018, which provided outsourced COVID-19 vaccine decentralized trials to pharmaceutical firms (such as Pfizer, Moderna, AstraZeneca, and Johnson & Johnson), grew by buying established trial sites and opening new ones in the United States and Canada under the promise of boosting underrepresented racial and ethnic minority trial representation.Footnote 74 Many of their acquired locations promptly closed, and it remains unclear whether the enrollment targets set for COVID-19 vaccine trials were ever met. The drug company sponsor was the only entity that had access to the multisite aggregated clinical data.Footnote 75
Considering the growing risks of clinical data opacity, PE firms should voluntarily commit to not only advocate for-profit maximization but simultaneously pursue the social value of generating scientific data. Different mechanisms to pursue social value may include targeting socially conscious executive compensation and multiple stakeholder board representation.Footnote 76
19.5 Conclusion
PE investment in remote, digitized clinical trials promises to improve operational, technological, and financial trial inefficiencies. Securing trial participant safety can be ensured by demanding PE firms have higher standards of care, enforced by private law tools. Yet, leaving the production of substantial scientific evidence to PE-backed trials deserves greater scrutiny. It is access to evidence that allows safe and effective health technologies to reach the market. The publicity concerns present today in drug development already indicate a free rider problem and low incentives to generate and disclose all and necessary privately generated evidence. As PE firms with financial opportunistic interests encroach upon DCTs, the tension between profit maximization and evidence and drug safety and efficacy maximization will only become greater. Resolving this tension requires greater moral responsibility from the industry and closer monitoring and critical analysis of PE activity from regulators.
