Somewhere to run, somewhere to hide? International regulation of human subject experimentation.
The pharmaceutical industry is one of the most important players in the field of clinical research on human beings. Increasingly in recent years, "Big Pharma" in the United States and elsewhere has turned to foreign populations to test its new products. The purpose of this note is to examine how existing sources of quasi-legal and ethical regulation address the troublesome issues raised by this increase in international human experimentation. First, the note gives a brief history of human experimentation and its regulation, giving special focus to the events of the twentieth century that have most affected the development of the bioethics movement. Next, it describes and compares several instruments of international regulation of human subject experimentation. Finally, it examines some of the difficult ethical issues associated with international research on human subjects. In this discussion, the greatest amount of attention will be given to clinical trials performed by the pharmaceutical industry. Other types of international research on human subjects exist, but research by the pharmaceutical companies poses its own special regulatory and ethical problems.
I. HISTORY AND BACKGROUND
Though the Holocaust and the concurrent Nazi experimentation on prisoners and Jews (1) brought unprecedented attention to experiments on human subjects, such experimentation and ethical reflection thereon began much earlier. One of the earliest codes of medical ethics was the Hippocratic Oath. (2) The Hippocratic Oath's focus is on care that directly benefits the patient; however, as in many early documents regarding ethics and human experimentation, that benefit is determined by the doctor and not the patient. (3) While the oath does not directly address human research, (4) the issue of delegating decision-making to physicians arises in later international codes and agreements on human experimentation.
Perhaps as a result of the lack of attention to human subject research, experimentation continued unabated and largely unregulated until the 19th century. (5) In 1803, Thomas Percival, an English physician, promulgated a code of medical ethics that dealt directly with human experimentation. (6) Like the Hippocratic Oath, Percival's code is decidedly skewed towards the interests of physicians and experts. There is no mention of consent or other protections of human subjects] The first American code of ethics dealing with human experimentation was created by William Beaumont in 1833. (8) The most important aspect of Beaumont's code, in comparison with that of Percival, is that it recognizes the necessity of the subject's voluntary consent and requires that experimentation cease if, at any time, the subject is "distress[ed]" or "dissatisfied." (9) In 1865, the French physiologist Claude Bernard published his own guidelines governing human experimentation, which precluded any human experimentation that would not be of direct benefit to the patient, no matter its value to science. (10) However, the valuation of that benefit remained in the discretion of the physician.
Ironically, one of the first official regulations of human experimentation came out of the Prussian government in 1900, (11) which was then part of the German Empire. (12) The Prussian directive expressly prohibited non-therapeutic research either on incompetent individuals (including children) or where the subject had not given "unequivocal" consent to the procedure after having it explained to him. (13) Historical records and contemporary press reports show that these guidelines were largely ignored by German medical researchers throughout the decades between their promulgation and 1931--when new guidelines were introduced. (14) These new guidelines were generated by the Reich Health Council and published by the Reich Minister of the Interior in response to reports of lax ethical standards among German medical researchers. (15) The new standards were among the most comprehensive and protective of the patients' interests, as compared with other codes of ethics then extant. (16) Experimentation on dying persons was strictly prohibited and research on minors was circumscribed. (17) The Reich Circular required that human research be carried out only after laboratory testing and animal studies were completed. (18) Furthermore, it required informed consent of patients and introduced more extensive protections for "scientific experimentation" (non-therapeutic research) than for "innovative therapy" (therapeutic research). (19) These German regulations are particularly relevant because they were the standards that existed at the time of the Nazi experiments, and against which the Nazi doctors at Nuremberg themselves wished to be judged. (20)
B. The Nuremberg Doctors Trial
The precipitating crisis of the modern bioethics movement was the extensive and cruel human experimentation performed on prisoners of the Nazi regime and the subsequent trial of twenty-three Nazi doctors at Nuremberg, Germany beginning in December 1945. During the Nazi regime, the practice of medicine was perverted from its typical purposes of healing and aiding the sick and suffering and was used instead to promote "ideas and solutions to the racial problems" that the Nazis perceived were a plague on their country. (21) This shift could represent a compelling explanation of why German medical science moved away from the high ethical and professional standards that it had previously set (22) and toward the realm of pseudo-science and torture. The Nazi doctors performed a wide variety of human experiments on prisoners (particularly Jews and gypsies) during the course of the regime, including extended immersion in cold water, extreme exposure to high-altitude conditions, exposure to military biochemical agents, and sterilization. (23) Often, these experiments resulted in death (as they were designed to do). (24)
At the conclusion of the Nuremberg trial, fifteen of the twenty-three doctor defendants were found guilty, including Karl Brandt, who had been Hitler's personal physician and Reich Commissioner for Health and Sanitation, one of the highest-ranking positions in the Nazi medical system. (25) Seven of these fifteen were sentenced to death by hanging and the rest were sentenced to prison terms of various lengths. (26) Alongside the final criminal judgment of the defendants, the Nuremberg judges enumerated ten principles regarding acceptable human experimentation. (27) The proximate origin of these principles was the contributions of two key experts for the prosecution, Dr. Leo Alexander and Dr. Andrew Ivy, who drew on historical sources such as the Hippocratic Oath. (28) Dr. Ivy testified at trial and Dr. Alexander had drawn up a memorandum for the judges, each focusing on ethical principles related to human experimentation. (29) Today, the Nuremberg Code is probably "the most accepted" and "the most cited" medical code of ethics. (30) More will be said about the content of the Nuremberg Code in Part II.A of this Note.
C. Other Human Experiments Outside of Germany in the Twentieth Century
It is important to remember that during World War II, and even after, unethical human experiments were not being carried out solely by the Nazis. Other countries, including Japan and the United States, carried out similarly brutal and unethical experimentation. The Japanese used U.S. prisoners of war (POWs) in their biological warfare experiments in China. (31) Other weapons, such as flamethrowers and grenades, were tested on human subjects, including Allied POWs and Chinese living in the areas surrounding concentration camps. (32) Finally, a horrifying array of live human vivisections, amputations, and experiments involving exposure to various extreme conditions (pressure, centrifugal force, deprivation, hunger and thirst) were performed by the Japanese on human subjects. (33) Despite the gruesome nature of their crimes, often similar to those for which the Nazi doctors were punished, many Japanese doctors were offered immunity from prosecution by the United States in exchange for disclosing the results of their experiments. (34)
Perhaps most troubling from the American point of view is the behavior of American scientists after the war with regard to human experimentation. One example was a series of human radiation experiments carried out with the support of various bodies of the federal government throughout the first thirty years of the Cold War (roughly 1940s-1970s). (35) Over seven hundred American patients, including terminally ill hospital patients, were used as part of thirty one experiments. (36) Later reports indicated that the patients were given no information about the purpose of the experiments, and consent was not part of the research protocol. (37) In one dramatic example, a man had plutonium injected into his leg, which was then amputated for study. The man was subsequently unable to work or support himself. (38) A federal judge, in a lawsuit by the families of the subjects (most now dead), stated that the patients had allegedly been treated "as though they were laboratory animals." (39)
Another infamous example of American human experimentation during the Cold War concerns the Central Intelligence Agency's MKULTRA experiments. (40) In its MKULTRA research and related experiments, the CIA was interested in the effects of drugs, hypnosis, and radiation for purposes of mind control and interrogation. (41) One of the arms of the MKULTRA experiments involved administering LSD to "volunteers" who were unaware of the nature of the experiment to which they would be subjected; other truly nonvolunteer subjects were randomly slipped LSD in bars in New York City and San Francisco. (42) These experiments resulted in the accidental death of at least one subject. (43)
Easily the most well-known of any human experiment carried on by the United States is the Tuskegee Syphilis Study. Beginning in 1932, the United States Public Health Service initiated an experiment with 600 black males in Tuskegee, Alabama, the purpose of which was to study the natural history and progression of syphilis. (44) When the study began, over half the men were already infected with the disease. (45) In exchange for their participation in the study, the subjects received free food and medical care. (46) However, the true nature of the experiment was never explained to any of the subjects, and even when an effective treatment to cure syphilis was discovered, it was not offered to any of the study subjects. (47)
The Tuskegee study went on for an amazing forty years before it was discovered and revealed by the press. (48) The increased scrutiny and criticism of the study by the press and government advisory termination. (49) Some compensation was panels led to its immediate provided to the victims of the study in 1973, but it was not until 1997 that President Bill Clinton apologized for the injustice that had been done to the experiment's subjects. (50) The revelation of the Tuskegee experiments resulted in the passage of the National Research Act in 1974, (51) which created the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. (52) In 1979, the Commission published the Belmont Report which identified "basic ethical principles" and applications of those principles that were relevant to human subject research. (53) The recommendations of the Belmont Report were adopted by the Department of Health and Human Services and many other federal agencies and incorporated into their regulations. (54) These recommendations evolved into what is currently known as the "Common Rule" for human research protection. (55)
D. The AZT 076 Clinical Trials in Africa
The next crisis in the history of international human subject research revolved around the most significant global health crisis of the late 20th century--HIV/AIDS. In 1997, several of the specific ethical issues surrounding international drug trials became part of a passionate dispute about AIDS-related research. The National Institutes of Health had funded a trial of a new protocol of AZT, an important retroviral drug used in AIDS therapy, in several African, Asian, and Caribbean countries. (56) An earlier test of AZT Protocol 076 had demonstrated a two-thirds reduction in mother-to-child HIV transmission. (57) Because of the high cost of AZT and that fact that Protocol 076 was an intensive treatment regimen, the prospects for providing the drug to HIV patients in impoverished countries were bleak. (58) Therefore, the new protocol involved a shortened regimen of AZT which was tested against a placebo. (59) The trial researchers claimed that they were looking for a more cost-effective, and therefore more accessible, manner of providing treatment. (60)
Several researchers argued that use of a placebo in these trials, given that a proven therapy was known, was unethical. (61) The placebo arm of the trial, under the circumstances, would have been legally barred in the United States. (62) The trial's supporters were charged with applying a double standard and exploiting trial participants because of lower standards abroad. (63) Opponents also claimed that even the shortened AZT regimen would have been too expensive in certain trial sites where the average annual health expenditure was only about ten dollars. (64) Trial supporters fired back, claiming that the use of a placebo-controlled trial was essential in rendering a faster, more useful and scientifically reliable answer about the efficacy of the shortened regimen, and would, in the end, benefit the countries in which the trials were being performed. (65) Trial researchers responded to charges of exploitation with claims that their opponents were "ethical imperialists," seeking to impose Western standards that would prevent the needs of developing world populations from being met. (66)
In the end, the short regimen of AZT had rates of success similar to Protocol 076. (67) Future clinical trials would compare the results of this short-course AZT regimen against those of even less intensive and costly regimens of competing retrovirals, such as nevirapine, which proved to be even more effective in preventing mother-to-child HIV transmission. (68) This episode illustrates several of the enduring and relevant debates surrounding pharmaceutical trials overseas.
E. The Contemporary Background of International Clinical Trials
The pharmaceutical industry has legitimately earned its common moniker "Big Pharma." It has been the most consistently profitable industry since World War II. (69) In 2005, global pharmaceutical spending exceeded $600 billion. (70) This represents a growth rate of seven percent worldwide, but emerging markets in Asia, Europe and Latin America grew even faster. (71) However, the development pipeline for new pharmaceutical products is a lengthy and costly one. The typical drug costs about $802 million over the course of its research and development, which lasts ten to fifteen years. (72)
The most difficult hurdle for new drugs to overcome is Food and Drug Administration (FDA) approval, the sine qua non of drug marketability in the United States. The FDA approval process, which is overseen by the FDA's Center for Drug Evaluation and Research (CDER), (73) consists of a series of four phases of clinical trials. (74) These trials test a new drug's safety and efficacy. (75) The approval process also involves institutional review by the FDA, and meetings between the new drug's sponsor and the CDER. (76) Each of the first three phases of a clinical trial require progressively more test subjects, peaking at around 3,000 for a Phase III trial. (77) Because not all patients who apply for a place in a clinical trial will be eligible, and many eligible subjects may not show up for their scheduled check-ups or follow the prescribed protocol, new drug sponsors may have to find many more willing subjects than the number required for the trial to get off the ground. (78)
A problem facing pharmaceutical companies who need a trial with several thousand willing participants is that Americans are increasingly hesitant to participate in these experiments. (79) The lack of clinical trial volunteers has caused a back-up in the "pipeline" of developing drugs. (80) Though both the cost and the number of new drug trials have increased in the past few years, the annual output of new FDA-approved drugs has remained steady. (81) The immediate effect of this trend has been to transfer the task of finding and carrying out new trials from academic medical centers, which the pharmaceutical industry saw as too slow to review and carry out the trials, to contract research organizations (CROs). (82) CROs are independent contractors who perform the tests and compile and submit the results to the FDA on behalf of the drug companies. (83)
CROs are more aggressive and faster in finding patients and carrying out the trials and were the main proponents of moving more clinical trials overseas. (84) The role of CROs has plausibly led many pharmaceutical companies, including some industry giants like GlaxoSmithKline and Merck, to conduct between thirty and fifty percent of their clinical trials overseas. (85) The number of clinical investigators overseas is growing too-up eight percent between 2001 and 2003, with a corresponding eleven percent decrease in the number of U.S. researchers. 86) New trials are generally moving toward more impoverished countries with larger "sick" populations-including Russia, India, and countries in Eastern Europe and Latin America. (87)
The shift of clinical trials to sites abroad has important implications for both countries hosting trials and those whose companies are sponsoring the research. Overseas clinical trials may be cheaper than domestic trials and may also enable new drugs to reach the market faster, resulting in greater profits for the pharmaceutical companies. The rapid approval and introduction of new drugs will likely result in increased health (or increased sickness if the testing is carried out poorly) for the populations to whom the drugs are marketed, which is not always the population on which the drug was originally tested. For the countries that host the clinical trials, their health systems may receive valuable infusions of capital by pharmaceutical companies who are anxious to carry out trials using local populations and researchers. The new drug and its post-trial availability (or lack thereof) will affect health outcomes for the test subjects in the host country as well. For these reasons and others, it is important now to ask what legal or ethical guidelines govern the conduct of clinical trials abroad and whether they are effective in regulating unethical or exploitative behavior by researchers.
II. DESCRIPTION AND COMPARISON OF MAJOR INTERNATIONAL AGREEMENTS OR CODES OF ETHICS REGARDING HUMAN EXPERIMENTATION
There are numerous important international documents that touch on human subject experimentation, and new instruments seem to appear each year. Not all of them can be mentioned here, nor can any one of them be examined in full detail. (88) Instead, this Note looks at two of the most influential international codes of ethics and two others which represent new approaches by those who seek to protect human subjects from unethical research practices.
A. The Nuremberg Code
The importance of the Nuremberg Code (Code) as a point of departure for the bioethics and broader human rights movements can hardly be overstated. The Code is recognized as "an authoritative statement of the fundamental rights of research subjects in all nations." (89) Further, the Code has influenced the development of subsequent human rights documents that go beyond the scope of human subject experimentation. (90)
Aside from the Code's significance and continued influence as a symbolic beginning to the regulation of human subject research, its content offers several points of comparison that are relevant to an analysis of subsequent bioethics documents. The Code itself consists of ten principles, stated in simple and direct terms. The first in order and importance says simply, "[t]he voluntary consent of the human subject is absolutely essential." (91) The paragraph which follows explains that the consent must be given by a person "so situated as to be able to exercise free power of choice," free from "any element" of coercion and based on prior information given to the subject about the nature of the experiment, its purposes, and the risks involved. (92) The principle of informed consent is the Code's "most important contribution" and has enjoyed wide acceptance in the research community. (93) None of the other nine provisions of the Code derogates from the researcher's "personal duty" to procure and protect the subject's informed consent. The rigidity of the Code's requirements, and therefore the limits which it placed on research, is one reason why the medical research community has tried to "improve" upon it in other instruments. (94)
In addition, the Code demands that research be performed "as to yield fruitful results for the good of society, unprocurable by other methods or means of study...." (95) In spite of the recognition that research ought to produce some benefit, the Code mentions nothing about the distribution of that benefit. Moreover, the Code is entirely devoted to experiments performed on healthy patients. No alternatives are mentioned for research combined with treatment, or therapeutic research.
Though the Code is a legal document, produced as part of an international criminal trial, it has no legal force. (96) A related criticisms of the Code is that the duty to follow its precepts is placed entirely on the researcher, who presumably is interested in the success of the experiment. (97) Even as a document written by judges, it is to be entirely self-enforced. The Code establishes no outside compliance review or method of sanctioning non-compliance. Of this particular limitation, perhaps we should be more forgiving. Though the Nuremberg judges intended to set forth ethical guidelines of enduring significance, it is important to remember that the Code was written in response to a discrete set of historical events, namely the Holocaust and the crimes of the Nazi doctors. The judges were responding to the specific crimes and evidence before them. The Nuremberg Code as a whole is a limited and simple document. Future instruments have added detail and complexity to the principles announced first at Nuremberg.
The Code's lack of legal force can be observed in the way it has interacted with the U.S. legal system. On the legislative and administrative side, federal regulations depart from the spirit of the Code by introducing the responsibility of the research institution and the authority of institutional review boards (IRBs) in lieu of the Code's emphasis on the researcher's authority. (98) In U.S. courts, no injured subject has ever been awarded damages, and no researcher has ever been punished based purely on violations of the Nuremberg Code. (99) The Code has been mentioned far more often as an authoritative source in dissent. (100) Perhaps the apex of the Code's use in U.S. courts was its extensive citation in the dissenting opinions in United States v. Stanley, which involved the CIA's MKULTRA experiments. (101) The 5-4 majority denied Mr. Stanley, a soldier in the U.S. Army, any compensation for his injuries, but Justice Brennan (joined by Justices Marshall and Stevens) and Justice O'Connor would have used the standards of the Nuremberg Code to provide him with a right to damages. (102)
B. The Declaration of Helsinki
Because of the Nuremberg Code's limitations and perceived flaws, medical researchers soon acted to create their own set of ethical standards. In 1964, the World Medical Association (WMA) issued the Declaration of Helsinki (Declaration), which soon became the definitive statement of medical ethics regarding research. (103) The
Declaration has been revised five times since 1964 and has had two notes of clarification added. (104)
As originally formulated, the Declaration placed less emphasis on informed consent than the Nuremberg Code. From Nuremberg's characterization of voluntary consent as "absolutely essential," (105) the original Declaration reads, "If at all possible, consistent with patient psychology, the doctor should obtain the patient's freely given consent after the patient has been given a full explanation." (106) The Declaration also allows consent to be given by a proxy of the subject, in the case of legal or physical incapacity, something which the Nuremberg Code would not allow. (107) In later versions of the Declaration, the sections on informed consent were strengthened, calling for "freely-given informed consent" either written or "formally documented and witnessed." (108)
One of the Declaration's most significant contributions to the field of medical research ethics is the introduction of independent committee review of research protocols. (109) According to the Declaration, the independent committee, known in U.S. regulations as an institutional review board (IRB), "should be in conformity with the laws and regulations of the country in which the research experiment is performed." (110) The use of foreign IRBs and the problems associated with them will be addressed in Part IV.
As has been noted by ethicists, the Declaration of Helsinki is more permissive and paternalistic than the Nuremberg Code. (111) In part, this reflects the instruments' different backgrounds. The Nuremberg Code is primarily concerned with human rights, having been drafted by judges in one of the first human rights tribunals. (112) The Declaration, on the other hand, was created by doctors for doctors. (113) The increased flexibility was intentional on the part of its drafters who represented the physicians' interests and who felt that the Nuremberg Code was too rigid and legalistic. (114)
The Declaration was signed by the United States in 19751 (115) and was incorporated by the FDA into their regulations for overseas clinical research that same year. (116) In spite of having been adopted into FDA regulations, the Declaration is a general statement of ethics, not a collection of legally binding principles. (117) Neither the WMA, nor the Declaration itself, have established procedures for enforcement or penalties for violators. (118) Moreover, the United States has refused to sign on to the latest revision of the Declaration, because of the WMA's insistence that research subjects should have access to the best current treatment rather than the best treatment which would otherwise be available to them." (119) This change would have made it more difficult or impossible to perform placebo trials with new drugs if an existing remedy for the same problem already existed. (120)
Where plaintiffs have brought claims against pharmaceutical companies for violations of the Declaration, the results have not been encouraging. For example in Abdullahi v. Pfizer Nigerian nationals sued Pfizer, an American pharmaceutical company, under the Alien Tort Claims Act (ATCA), 28 U.S.C. [section] 1350 (2006). (121) Their claim was based on a drug trial of a new antibiotic, Trovan, which resulted in the death or serious injury of at least eleven children. (122) Under the ATCA, plaintiffs must allege violations of the "law of nations" which is comprised of norms which are "specific, universal, and obligatory." (123) The court allowed the Declaration, as well as the Nuremberg Code and other instruments, to be introduced as evidence of principles of customary international law, but eventually found that they were not sufficiently universal to establish a claim under the ATCA. (124)
In addition to the basic principles announced in the Declaration, another international group, the Council for International Organizations of Medical Sciences (CIOMS), in collaboration with the World Health Organization (WHO), has published its International Ethical Guidelines for Biomedical Research involving Human Subjects. (125) The CIOMS Guidelines give more detailed and specific practical guidance concerning the principles found in the Declaration. For example, Guideline 5 sets forth a list of twenty-six items of information that a research subject must be provided before their subsequent consent can be considered informed. (126) The frequent approving references to the Declaration throughout the Guidelines is evidence that CIOMS believes that the Declaration's principles are the proper ones. (127)
C. Council of Europe's Convention on Human Rights and Biomedicine
Next, we turn to a recent European approach to the regulation of clinical trials--the Council of Europe's Convention on Human Rights and Biomedicine (CHRB). (128) The most obvious distinction between the CHRB and the other instruments above is that the CHRB is applicable only in Europe and only to those nations that are members of the Council of Europe. (129) Currently, the CHRB has been signed by thirty-four of the Counsel of Europe member nations, but only twenty-one of the signing members, excluding important European powers such as France and Italy, have ratified it. (130) In addition, Germany, Russian and the United Kingdom are among the nations that have not signed the CHRB. (131)
The CHRB is a general human rights instrument concerning not only biomedical research, but also privacy, human genome rights, and the transplantation and trafficking of organs. (132) The most relevant sections for the purposes of this note are Chapter V on scientific research (133) and the Additional Protocol on biomedical research, added in January 2005. (134) The Chapter V provisions are short and are primarily directed to problems of obtaining consent in the context of research. (135)
The most useful details of the CHRB are added by the Additional Protocol. The Additional Protocol provides for scientific and ethical review by independent committees. (136) Committee examination is required in "each State in which any research activity is to take place." (137) Depending on the scope of the term "research activity," which remains undefined in both the CHRB and the Additional Protocol (as well as their respective Explanatory Reports), this may include review in the country of origin. (138) Another important provision added by the Additional Protocol says that research carried out by "[s]ponsors or researchers within the jurisdiction of a Party to this Protocol" that takes place "in a State not party to this Protocol" must comply with the standards of the Protocol if they differ from those in that non-party State. (139) The drafters of the Additional Protocol were aware of the growing number of research projects being carried out abroad and the possibility of having different standards in different nations. (140) Thus, these more stringent protections are of little value if ethics committee approval in the home country is not required or is weak and ineffective.
A separate section, Chapter II, of the CHRB is devoted entirely to consent, but not solely in the research context. (141) Because of its placement separate from the chapter devoted to research ethics, one can deduce that consent is an important and overarching concern for the drafters. An Explanatory Report promulgated with the CHRB makes clear that this formulation of informed consent is meant to restrain physician paternalism (142) and that the information given to the patient must be transmitted in a way that is tailored to the specific person to whom it is communicated such that they can understand the information and weigh the costs and benefits of the procedure. (143) In the research context, consent must be "express, specific, and ... documented." (144) Research on persons unable to give consent for themselves is severely restricted. (145) For example, it may not be done if "research of comparative effectiveness" could be "carried out on individuals capable of giving consent" instead. (146) Research is further restricted to instances in which the protocol will produce a direct benefit to the patient, and if not, the research must have the purpose of furthering research that will ultimately produce a benefit to that patient or similarly afflicted individuals and present "minimal risk and minimal burden." 147)
The usefulness of the CHRB as a device to regulate unethical research is substantially weakened by the lack of an individual's right to petition the European Court of Human Rights under the CHRB provisions. (148) The court is authorized to give only an advisory opinion on interpreting the CHRB. (149) Any enforcement of CHRB rights is left to the individual states' courts. (150) However, the rights contained in the CHRB can be asserted in the European Court of Human Rights if, instead of bringing an action directly under the CHRB, plaintiffs find a CHRB right that fits under one of the protections of the European Convention on Human Rights (ECHR), over which that court does have jurisdiction. (151) The Explanatory Report to the Convention expressly recognizes the possibility that principles of the CHRB can be introduced as evidence of the scope of protection offered by the ECHR. (152)
D. Universal Declaration on Bioethics and Human Rights
Of the instruments concerned with international regulation of biomedical research the Universal Declaration on Bioethics and Human Rights (Universal Declaration) is undoubtedly the "new kid on the block." The Universal Declaration can be looked at as a culmination of some lessons learned from the past failures of other international bioethics instruments. However, how much of an improvement it makes over other instruments remains to be seen. In June 2003, the International Bioethics Committee (IBC) of the United Nations Educational, Scientific, and Cultural Organization (UNESCO) submitted their Report of the IBC on the Possibility of Elaborating a Universal Instrument on Bioethics. (153 With the blessing of the Director-General of UNESCO and its General Conference, the IBC then undertook a series of consultations with member states, drafts, and intergovernmental meetings to discuss the form and content of what would become the Universal Declaration. (154) Two years later, on October 19, 2005, the 33rd session of the UNESCO General Conference adopted the Universal Declaration. (155)
As to the content of the Universal Declaration, one of the most striking differences between it and other bioethics instruments is that the Universal Declaration is "addressed to States." (156) In contrast with the Nuremberg Code or the Declaration of Helsinki, which are aimed at researchers or research institutions, the Universal Declaration aims to push change on a governmental level. (157) The provisions for informed consent are similar to those found in the documents discussed above, including a requirement for "prior, free, express, and informed consent of the person concerned" for research-oriented treatments. (158) For therapeutic, preventative, or diagnostic treatments, express consent is only recommended "where appropriate." (159) This kind of looser consent requirement could be exploited as research and therapeutic interventions converge. In language similar to that of the CHRB, Article 7 provides "special protection" for persons who lack capacity to consent. (160) Further, recognizing the special problems of vulnerable groups, perhaps especially the populations of developing countries, the Universal Declaration refuses to allow the consent of a community leader or authority or community consent to supplant the necessity for individual informed consent. (161)
The provision for ethics committees (Article 19) initially says that the committees "should be established, promoted and supported at the appropriate level." (162) Within that provision, it is not made clear what the "appropriate level" is. Rather, in Article 21 on "Transnational Practices", the Universal Declaration provides that research being performed in a country other than the one where the funding source is located should be subject to dual ethical review. (163) Furthermore, the Universal Declaration insists that the terms of research agreements be established by negotiation characterized by "equal participation" by the parties. (164) Both of these sections seem to be aimed directly at two of the most serious problems with international clinical trials--the lack of ethical review in the host country and heavy-handedness and exploitation by the large pharmaceutical companies, many of which may have greater resources than the governments of the countries where their human subject research is performed.
As noted earlier, the Universal Declaration is addressed to states, and its drafters have seemingly left the enforcement and administration of its provisions to the state-parties. Article 22 says that "[s]tates should take all appropriate measures, whether of a legislative, administrative or other character, to give effect to the principles ..." of the Universal Declaration. (165) There is no reference to any international judicial or regulatory body in any part of the Universal Declaration. Instead, the drafters seem hopeful that the benefits of "education, training and public information," as well as international cooperation, will be sufficient protection against inappropriate and unethical research. (166)
III. ETHICAL PROBLEMS SURROUNDING HUMAN RESEARCH IN FOREIGN COUNTRIES
This note now turns to specific ethical problems that characterize overseas clinical trials. As in Part II above, every ethical dilemma associated with such research cannot be fully addressed here. Instead, this Note looks at four issues that are, arguably, the most important and in most need to be addressed by regulation and policy.
A. Distribution of the Costs and Benefits of International Clinical Research
The question of who benefits and who carries the burden of international clinical trials is crucial. Clearly, the pharmaceutical companies and CROs that carry out the research at lower cost, under less scrutiny and with a more abundant population of subjects are beneficiaries. (167) The populations of developed countries also benefit from new drugs that are developed primarily for their consumption without the need to subject themselves to the risks of clinical testing. The burdens of such research, however, fall disproportionately on the populations of the developing countries where more and more clinical trials are carried out.
There are concerns that pharmaceutical companies test drugs that are unresponsive to the needs of the local populations in the developing countries where the tests are conducted. (168) Bioethics documents have consistently recognized the need for the benefits of research to outweigh costs or burdens as to individual subjects. (169) A more recent concern has been whether subject populations are receiving adequate consideration before, during, and after the trials. The most recent revision of the Declaration of Helsinki says that research is "only justified if there is a reasonable likelihood that the populations in which the research is carried out stand to benefit from the results." (170) One method of providing some benefit to subject populations is through post-trial access to the tested products or other proven treatments. One of two new paragraphs in the Declaration of Helsinki concerns post-trial access to the best proven methods of treatment. (171) Because of the burdens it allegedly places on the researchers and their sponsors, this addition has been one of the most contentious revisions of the Declaration in recent times. (172)
The Universal Declaration also shows concern throughout for the needs of developing countries, stating that "[t]ransnational health research should be responsive to the needs of host countries." (173) Article 15 is explicit in declaring that the benefits of research "should be shared with ... the international community, in particular with developing countries. "m Article 15 goes on to enumerate various forms that such benefits might take, such as provision of new products, "capacity-building facilities," and increased access to health care. (175)
Debate on these issues centers on whether the benefits of the trial alone provide sufficient benefit to the local population if no access to treatment was available to that population prior to the tests, and whether any harm is caused if, once the trial is over, the situation is returned to the status quo ante. (176) Research institutions and health care systems in developing countries can indeed receive some much-needed investment and improvements through hosting clinical trials. Those benefits can then be passed down to the local patients that they serve. Nevertheless, as it relates to post-trial access to the treatment itself, it seems cruel to introduce a higher standard of care to a sick population, which hopefully produces a higher standard of living, and to then abandon treatment once enough positive results begin to manifest themselves.
It should be emphasized that the question of post-trial access is separate from the related and equally important question of whether the distribution of costs and benefits between the developing world, serving largely as "guinea pigs," and the developed world, which is the primary consumer of new drugs, is a just one. In the author's opinion, there is something pernicious about this divorcing of costs and benefits. From a historical perspective, it is reminiscent of a relationship between the developed and the developing world that was characteristic of colonialism in previous years and in the current era by the problems of inferior labor and environmental standards and human exploitation. Post-trial access is an important goal that ought to be pursued, despite predictable opposition by the pharmaceutical companies. As recommended by the Declaration of Helsinki, any provision for post-trial access should be made part of the ethical review process that precedes the execution of any trial. (177) Nevertheless, the provision of additional benefits derived from participation in clinical trials, such as investments in infrastructure and capacity-building, should continue to be mandated by international guidelines, and such requirements should be introduced into domestic law. (178)
B. Ethical Imperialism or Cultural Relativism?
One of the most enduring and overarching debates regarding international clinical trials is the struggle between the search for universal principles and the need to respect diversity and pluralism. In this debate, it is important to remember that both sides are concerned about the exploitation of persons in developing countries. (179) The universalists are concerned that researchers will take advantage of lower standards in developing countries to perform studies that would be unethical and impermissible in developed nations. (180) The pluralists or relativists are worried that imposing the developed world's norms and practices on the developing world is similarly exploitative. (181) There are two principal questions in this debate. The first question is whether the same definitions and values apply to concepts such as informed consent in different cultures and different populations. This area will be discussed specifically in the context of informed consent in Part III. C below.
The second question is whether the same standard of care should apply across cultures, especially in light of the different levels of prosperity and health care access enjoyed by those in the developed and developing worlds. The argument revolves around whether developing country research subjects are entitled to the "best current treatment," the standard which emerges from the Declaration of Helsinki, even if the best current treatment would not normally be available to that population. (182) This standard would, with few exceptions, effectively eliminate the use of a placebo control group where an existing treatment already exists, (183) The question then essentially becomes whether the prescribed minimum is the best current treatment available anywhere, or the best current treatment available in the area where the research is taking place. (184)
Both viewpoints in this debate have their costs and benefits. If one insists that a universal standard of care should be imposed, this substantially raises the cost of the research and eliminates the cost-saving incentive to perform research abroad. If that position is combined with a commitment to post-trial access to treatment, the cost may become prohibitive. We should not forget that the benefits of clinical trials to developing countries, such as those enumerated in Part III.A, would be withdrawn if such research became impossible. Using a current treatment, rather than a placebo, in a control group also makes discerning the scientific results more difficult; this explains one of the exceptions in the Declaration of Helsinki. (185)
Observing a universal standard of care would certainly contribute to equality and nondiscrimination, two laudable ethical goals. However, it may not be best for the long-term health of developing countries. A contextualized standard of care, probably lower in developing countries, makes it more likely that research will be carried out in developing countries, with its attendant benefits in training and investment. These material and educational benefits could be a more efficient contribution to future health outcomes than a universal standard of care during research, especially if post-trial access is not a viable option.
While the Universal Declaration does not directly address the placebo-"best current treatment" debate, philosophically it is unabashed in its commitment to the search for "universal principles." (186) Article 12 of the Universal Declaration makes clear that "cultural diversity and pluralism" should not be used to "infringe upon human dignity, human rights and fundamental freedoms, nor upon the principles [of] this Declaration, nor to limit their scope." (187) However, there is no infringement of human rights where people continue to be provided with a standard of care no less than what they had been receiving, while working to provide greater long-term benefits in the form of improved local health care systems or development of new treatments that will be made available to subjects in the future. That being said, there is never an ethical or legal excuse to go below the local or national standard of care for treating a certain disease or condition in order to prove the effectiveness of a treatment that may not immediately be made available to the subject population. (188)
C. Informed Consent
Informed consent has justifiably been described as the "hard inner core" of medical research ethics. (189) As mentioned above, in the Nuremberg Code, informed consent is the first of the essential principles of bioethics. (190) Among the international ethical guidelines examined here, and in other ethical guidelines, there is no dispute about the necessity of informed consent in clinical trials. (191) These instruments are also largely in agreement about the form and requirements of informed consent, even if there are differences as to some details. For example, most recognize that additional protections are necessary for those who cannot give informed consent for themselves, (192) and most recognize the right to withdraw consent at any time during the research. (193)
Because of the acknowledged and agreed-upon centrality of informed consent as a protection for research subjects, it is vital that informed consent is carried into practice in an effective manner wherever research occurs. Unfortunately, some data indicates that informed consent is not fully implemented in trials in the developing world. One question is whether the consent is truly informed, or whether it ever can be in developing countries. In one survey, only sixteen percent of researchers claimed that they verified that a subject understood the procedure. (194) Some researchers have expressed concerns that informing subjects in the developing world is futile due to linguistic or cultural barriers and low levels of education. (195)
Another question is whether consent can be free in developing countries. There is anecdotal evidence that in many instances, subjects feel coerced into participating or are not told that they may withdraw at any time. (196) Part of this coercion can be due to financial or other incentives to stay in the trial (197) or because subjects simply do not feel free to say no. (198) Such unwillingness to refuse can originate in notions of the authority of Western doctors, the fallacy that a treatment will improve their health, lack of education, or structural issues in the culture or society. (199) In fact, a survey in 2001 found that among researchers working in developing countries, "[forty-five] percent reported that their low-literacy subjects never refused to participate." (200)
The necessity of individual informed consent is another locus where the debate between universalism and relativism is played out. On one side are the drafters of the numerous ethical guidance instruments, who have acknowledged the necessity of informed consent. On the other side, some researchers and CROs promote the idea that certain populations in the developing world are, because of culture, more docile and malleable than Americans and therefore better candidates for research. (201) Others, including foreign physicians, believe that informed consent is a Western principle and is "unnecessary" in the context of other cultures. (202) It is true that in some cultures personhood is defined differently than in Western cultures, and therefore the consent of the individual will not be as important as that of the family or the community. (203) Such dilemmas have also raised concerns that the overzealous pursuit of individual consent in a collectivist society could lead to the "weaken[ing of] the social fabric." (204) Nevertheless, the Universal Declaration rejected any attempt to circumvent individual consent or to use diversity as a pretext to "infringe upon human rights and fundamental freedoms." (205) This leads to a larger discussion about the universality of "human rights" that is beyond the scope of this essay.
For those who are strongly committed to the necessity of individual informed and free consent, the most obvious course of action would be to shut down trials in the developing world where such ideals could not be put into practice. This seems too extreme a remedy, especially in light of the benefits that individuals and societies in the developing world can derive from participation in clinical trials and the practical necessity of their involvement for the development of new drugs. However, any deviation from the standard of individual informed and free consent should be closely scrutinized by ethical review committees. Those committees should be well-trained and should receive the relevant evidence from researchers, anthropologists, and others to decide whether such a departure is truly necessary.
D. Deficiencies in Ethical Review
As seen in Part II, one of the ways in which international codes of ethics and current FDA regulations differ is in the requirements for ethical review. Both the Declaration of Helsinki (which the FDA has incorporated into its regulations) and the Convention on Human Rights and Biomedicine provide for ethical review only by the country where the research takes place (the host country)9 The Universal Declaration, on the other hand, establishes a requirement of approval by at least two review committees, (207) one in the host country and the other in the country where the source of research funding is located. (208)
The idea that host countries should be the primary locus of ethical review has much to recommend it. It is not unreasonable to assume that local IRBs will be more protective of their countrymen than will a group of foreigners. Researchers as well as IRB members are often anxious to avoid allegations of "ethical imperialism" and ethnocentricity, terms that are often tossed around in the debates surrounding overseas clinical trials. (209) Allowing the host country IRBs to handle ethical review by setting and applying their own standards is a convenient way to avoid such charges. However, the implicit assumption of such a stance is that IRBs in host countries are as capable as those in the developed sponsor countries at protecting the interests and health of research subjects, or at least at protecting them to the degree that their culture requires. There is significant evidence to the contrary.
As mentioned above, a recent survey conducted by the National Bioethics Advisory Committee found that one-fourth of all overseas clinical trials went through no ethical review at all. (210) That same inquiry found that several nations did not have ethical review committees and had no plans to create them. (211) Even in those nations with committees, the review was largely ineffective, and there are several barriers that prevent ethical review from taking place in many countries. One significant problem is a lack of capacity. For example, doctors may lack training in medical ethics and good research practices. (212) In some countries, like India, one of the current hot spots for medical research, the domestic medical association resists the imposition of minimum standards of ethics and practices. (213) Another difficult issue is the possibility that foreign IRBs will be unduly influenced by the resources of the pharmaceutical companies and the financial incentives being offered to their institution for participating in the study. (214) The danger is that ethics committees will "rubber stamp" unethical protocols, simply because they want the financial rewards of hosting clinical trials. (215)
How could ethical review be carried out more effectively? One proposal would be to follow the principles set out in the Universal Declaration. This would require that the sponsoring country (most likely an industrialized Western nation with greater review capacity, resources, and higher standards) carry out its own ethical review and protect foreign patients to the same degree that they would protect domestic patients. While this would aid in harmonizing and, in general, raising standards across countries, forcing equivalent ethical review by the sponsoring country would eliminate some of the advantages that have created so much interest and activity in the area of foreign clinical trials. An alternative or additional proposal would be to have those governments, institutions, and businesses that carry out or sponsor foreign trials contribute to the development and capacity-building for ethical review in the countries where such studies are carried out. Their assistance should be both financial and technical. The objective would be to create IRBs where none currently exist and to train and monitor the committees where IRBs are already in place but are ineffective in screening out unethical and exploitative research protocols.
This note has focused on how the standards and principles set forth in international bioethics documents can be applied to the particular problems affecting international pharmaceutical clinical trials. The recommendations above are primarily ways in which governmental bodies, such as the FDA, international groups, such as the WMA and UNESCO, and private researchers can work towards the protection of human research subjects. These measures should not be employed alone, ignoring a wide range of private responses that could be employed to encourage compliance and higher standards by violating companies. (216) It is not a realistic solution to absolutely prohibit by law all overseas clinical trials, nor is that necessarily the most desirable outcome for the populations who will be the patients in the trial. However, much can be done to offer greater protection to international human research subjects and to make the distribution of benefits from global pharmaceutical research more equitable.
