Financial Remuneration of Clinical Study Investigators

In November 2009, the Center for Health & Pharmaceutical Law & Policy, in its White Paper, Conflicts of Interest in Clinical Trial Recruitment & Enrollment: A Call for Increased Oversight, explored payments to investigators — and other potential motivators — to conduct research.  A study in this month’s IRB: Ethics & Human Research explores the impact payments may have on researchers to conduct and complete studies.  In Motivated by Money? The Impact of Financial Incentive for the Research Team on Study Recruitment, Sharon Unger and her colleagues examine the effect financial remuneration has on researchers in a neonatal intensive care unit (NICU).

Taking advantage of a “fortuitous set of circumstances” in which two separate clinical trials with nearly identical inclusion criteria were conducted simultaneously in an NICU in Canada, the authors looked at two issues: 1) whether financial remuneration impacted the rate at which the research team approached parents about research participation, and 2) whether financial remuneration impacted the rate at which parents provided consent to participate.

In the first study (Study A), a placebo-controlled trial involving a medication that was the standard of care for treatment of newborns nearing extubation to prevent apnea of prematurity, members of the research team were financially compensated for their time if they were successful in obtaining parental consent (parents were unaware of this arrangement).  In the second study (Study B), which involved two different forms of noninvasive respiratory support following extubation, there was no financial compensation of the research team.  Both studies had the same recruiting team.  Study A was federally funded, multicentered and high-profile, while Study B was a single-center, unfunded trial.

The payments in Study A were per capita, which, while creating a direct incentive to recruit individual enrollees, is usually not problematic as long as the payment is not excessive.  The Center recommends “that the benchmark for compensation for physician services for research should be comparable payment for time and services for treatment. This will compensate physicians fairly for their time and services, and will assure that there are no hidden bonuses or incentives for physicians to recruit patients into research or to refer them to research rather than treatment.”  As noted in the study, finder’s fees are increasingly considered “ethically problematic;” the Center recommends a wholesale bar on finder’s fees because they can create conflicts of interest that can incentivize investigators to recruit and retain individuals who do not meet the study’s inclusion and exclusion criteria.

As the authors noted, and as acknowledged in the Center’s White Paper, potential enrollees are increasingly vulnerable as increasing numbers of individuals seek to participate in research either as a primary means of access to treatment or as a form of income.  The results of this study indicate a much higher likelihood of approach when there was a prospect of financial remuneration.  These results are concerning, and were anticipated by the Center’s White Paper, which noted the potential for poor compliance with inclusion and exclusion criteria and pressure to enter or remain in a clinical trial.

However, surprisingly, the authors found that, despite the much higher likelihood of approach for Study A than Study B, parents were much more likely to actually agree to enroll their newborn in Study B — for which there was no financial remuneration of the research team.  The authors explored various explanations for this result, including that the research team was overly cautious about giving the appearance that their approach for consent was motivated by financial compensation, or that parents chose to withhold consent  due to the research team’s  increased pressure.

The authors do acknowledge other potential factors — beyond financial remuneration –  that could have affected the study’s results.  For example, parents’ hesitancy to enroll their newborn in a placebo-controlled drug trial could explain the discrepancy between enrollment in the studies.  Likewise, the authors consider that parents may not have been able to differentiate between the two modes of support being investigated in Study B.  In addition, the recruiting team, when presented with the results of the study, did not recall feeling influenced by the financial arrangement of Study A, but did “recall being highly motivated to ensure the success of Study A as it was part of a high-profile, multicentered trial.”

The authors concluded by noting concerns that “there may be a point at which the amount of the financial remuneration or the manner in which it is assigned could negatively impact the ethical conduct of the researcher,” but cautions that these concerns should be balanced with the value of conducting research in patients’ best interests.  This balancing act is considerably important.  As the Center notes,

Research is critical to the advancement of medical treatment and health. It must be structured to produce high quality data that facilitates the assessment of safety and efficacy in the population for whom the treatment will be used. The good of the enterprise requires that the clinical trial system sufficiently balance the costs and benefits to physicians and prospec­tive trial participants to ensure the continued sufficient supply of researchers and subjects. The system must also be imbued with actual and perceived integrity — so that it produces scientifi­cally reliable results, participants are safe, and people trust the system sufficiently to be willing to participate.

Further Calls for Increased Oversight on Medical Research & Physician Conflitcs of Interest

The Center for Health & Pharmaceutical Law & Policy has continued to focus on the implications of research funding in patients’ decisions to participate in clinical research, as well as the effects such funding can have on researcher behavior and research results.  In January 2009, the Center recommended that all financial relationships between industry and physicians be publicly disclosed by industry.  And just this month, the Center released its most recent White Paper, “Conflicts of Interest in Clinical Trial Recruitment & Enrollment: A Call for Increased Oversight.”

Similarly, in a November 17 letter to Francis Collins, 100 researchers, academics, and public policy analysts asked the NIH to “fund studies on medical ethics, conflicts of interest in medicine and research, and prescribing behavior” in order to determine the effects of industry-academic relationships on human health.  The letter implores the director of NIH to focus on “the research gap on the effect of conflicts of interest and commercial influence on medical decisionmaking” and to establish a mechanism for funding relevant research.

One of the primary concerns in the researchers’ letter is an issue also identified in a November OIG report, “How Grantees Manage Financial Conflicts of Interest in Research Funded by the National Institutes of Health,” which found that a majority of academic researchers’ conflicts of interest are unreported.   The report flags the potential for extensive conflicts between faculty members and their government-financed research.  In response, the US Senate Finance Committee recently sent letters to several universities requesting such information.  Just yesterday, Northwestern University’s Feinberg School of Medicine, reacting to national concern about physicians’ and researchers’ financial conflicts of interest, began posting external professional and industry relationships for approximately 2000 faculty members — including service on boards of directors, consulting and related activities, ownership or investment interests, royalties and inventor shares, and additional activities such as lectures and participation in scientific advisory boards and professional societies.

Further research is obviously necessary to determine how financial relationships influence — as the authors of the letter to NIH call it — “the beliefs and behaviors of researchers and clinicians, and the effects of industry-academic relationships on the generation and dissemination of medical knowledge.”  In the meantime, increased oversight of physician-industry relationships by the federal government to evaluate and oversee investigator or institutional conflicts of interest, both for research within and without academic medical centers, is necessary.

Seton Hall Law School’s Center for Health & Pharmaceutical Law & Policy Issues White Paper Calling for Major Reforms in the Financing and Oversight of Clinical Research

Seton Hall University School of Law’s Center for Health & Pharmaceutical Law & Policy has called for major substantive reforms in the financing and oversight of clinical research. In a White Paper entitled “Conflicts of Interest in Clinical Trial Recruitment & Enrollment: A Call for Increased Oversight,” the Center proposes legal and policy changes to address conflicts of interest in the relationships between industry and doctors that can create unwarranted risks to trial participants and to the scientific integrity of research.

Kathleen Boozang, a dean who oversees the Law School’s Center, explains that “Some of the ways that drug and device trial sponsors pay the physicians who lead clinical trials can tempt them to recruit individuals for clinical trials who would be better off receiving conventional therapy. This is of particular concern if physicians encourage their own patients to enroll in trials that these same physicians are overseeing.”

Over 60% of testing of experimental drugs and medical devices now occurs in physicians’ private offices; unlike years past, industry funds a much higher percent of clinical trials than government, frequently paying researchers significantly more than government does.  For some physician practices, conducting clinical trials represents a significant portion of their income.

According to Carl Coleman, a Seton Hall Law professor who collaborated on the White Paper, “A different kind of problem arises if people are enrolled in trials who don’t meet the criteria for who should participate - these individuals’ health can be put at risk, and their participation can skew the results of the trial, which is bad for everyone.”

Federal regulations in this area have not kept up with the rapid changes in how research occurs, and even those regulations that exist are poorly enforced, according to recent government studies.  Understanding that the collaboration among industry, government, and medicine in the pursuit of clinical research is critical to driving scientific progress, particularly as industry increasingly replaces the government as the primary source of research funding, the Center’s recommendations include:

1) Establishing a norm of financial neutrality between treatment and research. Ensuring that physicians receive comparable compensation for treatment and research will help ensure that their decisions to conduct research, as well as to recommend that a particular individual participate in a clinical trial, are grounded in reasons unrelated to their personal financial interests. This will be best accomplished, in the first instance through regulations that ban certain kinds of research compensation, and provide examples of acceptable payment methodologies that industry can follow. Reform by prosecution signals what practices government dislikes, but does not provide a clear vision of ideal approaches to managing conflicts of interest related to the conduct of research.

2) Establishing federal guidelines as to the principles or methodology by which to determine fair market value of physician time spent in clinical work. Federal regulations should be promulgated that establish a benchmark formula for determining fair market value of physicians’ time, effort and expenses for clinical research. Such regulations would promote the goal of financial neutrality between treatment and research. Physicians cannot be underpaid for research either - compensation for clinical trial work should therefore include reimbursement for any additional expenses that are unique to the research environment.

3) Banning payments with equity interests; disqualification of investigators who hold direct interests in the outcome of the research. Federal regulations should prohibit compensation for research in the form of an equity interest in the sponsor of a clinical trial. The law should preclude researchers who have investments that give them a direct interest in the outcome of the research from leading clinical trials.  Where absolutely necessary, such individuals might appropriately serve as consultants.

4) Banning payments of finder’s fees and bonuses for recruitment and retention of trial subjects. Certain forms of compensation create conflicts of interest that can incentivize investigators to enroll individuals in a clinical trial who are too healthy or too sick to participate, or to deemphasize information that might discourage individuals from consenting to trial enrollment. Federal law should ban such compensation methods, including finder’s fees and bonuses for meeting recruitment and retention goals.

5) Reforming federal regulations to compel and better guide the evaluation of relationships between industry and would-be physician investigators prior to the commencement of research.   The White Paper includes overlapping but sometimes distinctive recommendations for federal regulation to evaluate and oversee investigator or institutional conflicts of interest, both for research within and without academic medical centers.  Specific to research outside of academic medical centers, federal regulations should spell out clearly the obligation of community-based physicians acting as investigators or institutions acting on their behalf to report information about compensation for research and other financial interests to Institutional Review Boards.

Summarizing the importance of this White Paper, Boozang states, “The pharmaceutical and medical device industries save millions of lives each year with their innovations.  It is imperative that we maintain the integrity of research, and the public’s trust in the process.”

Alternative Revenue Stream for Private Practice Physicians – Research Investigator

Clinical research is the only way [for a physician in the managed care era] to make a boat payment, quips David Stark, M.D.

With increasing frequency, pharmaceutical and medical device companies are turning to physicians in private practice, rather than academic medical centers, to serve as investigators overseeing the 60,000-odd clinical trials each year, between 80 and 90% of which are funded by industry as opposed to, say, NIH. Academic medical centers are losing the “business,” having fallen from 63% to 26% as the site for clinical research between 1994 and 2004. While it might be argued that trials in the private practice setting produce superior results because they occur under circumstances that more closely resemble how the drug or device will actually be used if approved by the FDA, there are significant risks attendant to this phenomenon that have received too little attention.

The ultimate question is whether physicians can compartmentalize the competing incentives that exist in advising patients about whether to pursue conventional therapy or participate in a clinical trial. This is especially true if the physician is being handsomely compensated for each patient she recruits into a trial, and is exacerbated when the physician also has other financial relationships with the trial sponsor (the drug or device company) for, say, speaking and consulting gigs. Clinical Research in the Private Office Setting — Ethical Issues The recruitment process for clinical trials is the longest and most costly part of the process - prospective participants have to undergo testing to see if they qualify for the study, and federal law requires that they receive significant amounts of information and have ample opportunity to have their questions answered pre-enrollment. A per capita payment contingent upon successful enrollment of the patient will tempt a physician to fudge on this process and enroll unqualified subjects. This not only may put them at risk because they are too sick, but also skew the research results because they’re not sick enough. Bonuses for meeting enrollment goals only make it worse.

Without impugning physician integrity, how realistic it is for physicians to serve in the dual capacity of treating physician and researcher? Studies have repeatedly confirmed “therapeutic misconception” whereby study participants believe, no matter how clearly told to the contrary, that they are “patients” receiving treatment, rather than “subjects” of research who may be receiving a placebo or an experimental drug. This phenomenon is certainly exacerbated when the patient’s treating physician is doubling as the investigator of the clinical trial. Most patients continue to believe that their own personal physician would be driven solely by their best interests. Ironically, some people have more faith in an experimental intervention when they learn that the investigator has a “piece of the action.”

Obviously, significant policy and legal questions arise from this practice, and a more holistic approach to the question of the best way to encourage clinical trials while safeguarding the interests of trial subjects is beyond what I can attempt here. But one possible approach could be drawn from informed consent law — whether statutory or common law, which should require physician disclosure of conflicts of interest to patients. Imagine the beginning of a conversation between doctor and patient/potential research subject:

Doctor: “Just so you know, if you agree to participate in this clinical trial, I get paid $1000 by the manufacturer of the product being tested, but if you don’t, and you just want regular treatment, I’ll only get paid $60 by your insurance company. But, in fairness, that’s because a clinical trial is a lot more work for me….”

But to be honest, I don’t really believe in this solution either. Most recipients of this information either don’t understand it, or have no idea what to do with it, or both. Some fear that too much confusing information might kill trials altogether, which would be a terrible outcome. And there are certainly reasons to fear that such trials are becoming harder to run, to the point where they’re not worth the money. Ultimately, I guess, I want to control how physicians get paid to serve as investigators — the Goldilocks Solution — not too much, and not too little. I want them to be paid just right, so that they are willing to conduct clinical trials, but aren’t tempted to act other than in the patient’s best interest. Of course, what is just right and how to enforce it poses its own problems.

Drug Study Fails to Mention Risk of Death to Test Subjects

[Ed. Note: Today's Post is by Maansi K. Raswant, a Seton Hall Law student pursuing the Health Law concentration. She is a research assistant to the Center for Health & Pharmaceutical Law & Policy and an intern at the NYC Health and Hospitals Corporation.]

As reported recently in the Boston Globe, a federal probe found that heart attack survivors enrolled in a clinical trial conducted in over 120 sites nationally had not been adequately informed of the safety risks of the study, including the risk of death.

The process under study, chelation, involves “periodic infusions of a drug– in this case, disodium EDTA.” The infusions are being tested in conjunction with the ingestion of high doses of  vitamins and minerals. However, according to the federal probe, “in 2008 FDA removed disodium EDTA from the FDA’s approved list and withdrew of approval of new drug applications for disodium EDTA.” Test subjects were not informed that disdodium EDTA “is no longer FDA approved for any use and has been removed from the market because of safety concerns.”

Funded by the National Heart, Lung and Blood Institute and the National Center for Complementary and Alternative Medicine, the study has over 1,500 subjects. Though researchers suspended enrollment last August due to the investigation, federal officials allowed the study to continue pending further findings of the probe, a decision that has been highly criticized.

In addition to the deficiencies regarding the  informed consent of study participants, the Boston Globe reported that the investigation found that several co-investigators involved in the study had been disciplined for “substandard practices” or had been involved in insurance fraud. Three were convicted felons. Federal officials explained that they found the substandard practices and convictions of the principal investigators “concerning” but not a reason to “automatically preclude an investigator from participating in research.”

The U.S. Office of Human Research Protections detailed the findings of the investigation and required corrective actions in a letter to the three medical institutions heading the study. In response to the investigation’s findings, the study modified the consent form to recognize death as a “rare complication of the EDTA [chelation] infusions.” The Office of Human Research Protections has also requested further modification of the form to disclose that disodium EDTA had been removed from the market.

Despite the change in consent form, questions remain about the acceptability of the risks posed by the study. As the Globe reports, critics of the study, including the head of bioethics at the University of Pennsylvania, Arthur Caplan, have charged that the risks posed by the study are unethical. The complaint against the study filed with the Office of Human Research Protections noted that since “the mid-1970’s court documents and newspapers have reported at least 30 deaths associated with intravenous EDTA.”

The probe is the lastest in a string of major investigations of clinical trials, including the continuing investigation into payments by device maker Medtronic to Dr. Timothy Kulko (who is accused of falsifying author names and  study results), and the Synthes indictment for allegations that its subsidiary, Norian, conspired to conduct unauthorized clinical trials that placed subjects at risk of death without properly informing them of the risks. In the Synthes/Norian matter, three patients are believed to have died as a result of the use of the companies’ bone cement products.
