“Would it be all right if we used the
native population as patients in order to test a drug which we hope will better
treat a particular tropical disease?” he asked. It seemed an innocent enough
inquiry, and the usual interrogation followed. We asked whether adequate animal
testing of the drug would take place before it was given to humans, whether the
subjects would be fully informed about what was going to happen to them and
about any possible danger of side effects from the drug prior to giving their
consent, whether they were going to be paid for participating in the experiment
and, if so, how much. We also wondered whether some patients would be in a
“control” group given only the current standard treatment so that a comparison
could be made between their progress and the response of the patients who were
given the new drug. All the answers regarding the scientific merit and the
ethical nature of the proposed research seemed satisfactory. We were about to
applaud the enterprise and encourage its spokesman to see that it was carried
out when a final question occurred to me. “What will happen if the drug is
found to be helpful?” I asked. “The experiment will be a success, of
course, and we will use it,” he answered. “That’s good. Will the patients
themselves continue to be given the drug as long as they need it?” “I suppose so.” “Will supplies of the drug be made
available on the market for the citizens of the country where we have done this
research?” After a long pause, he answered, “We
haven’t thought about that.” I then objected to the research on the
grounds that we would be using people as guinea pigs solely for our own
benefit. In conducting such research, we would have a moral obligation not only
to complete treatment of the patients involved but also to see to it that
supplies of the drug, if it were efficacious, would be made available on the
local market. We never did learn whether the research was carried out or not.
Upon reflection I presume that its mysterious proponent was employed by the
Department of Defense, which was interested in finding a treatment for members
of our armed forces should they be exposed to the disease.
The Geneva-based Council for
International Organizations of Medical Sciences (CIOMS), an institution which
works with the World Health Organization (WHO), has been working for some years
to develop comprehensive, international guidelines for medical research. In the
process Dr. Zbigniew Bankowski, executive secretary of CIOMS, sent out over 100
questionnaires to Third World countries. He discovered that whatever restraints
were placed upon research, whether domestically or internationally funded,
arose from indigenous ministries of health, university policies and hospital
codes and varied greatly in quality. In addition, he learned that the
responsibility for both the scientific and ethical approval of approximately 23
per cent of the research was vested in individual medical investigators. An extreme example of this haphazard
dispersion of control was an experiment to test the effects of tetracycline on
a rickettsial disease. The subjects of this experiment were to be healthy
members of the subordinate staff of a medical institution in a Third World
country; they were to be exposed to the disease by the bites of infected
insects. Despite being informed that even with the proposed antibiotic
treatment, rickettsial infection might be persistent in their bodies -- and
that there was “a small risk of death” -- people “volunteered.” It sounded like
a form of medical banditry: not “your money or your life” but “your health or
your job.” However, it should be noted that abuses
are not restricted to developing countries. They take place even in the United
States, our guidelines notwithstanding. The experiment that permitted retarded
children to contract hepatitis at the Willowbrook State School in New York
state and the injection of live cancer cells into elderly patients at the
Jewish Chronic Disease Hospital in New York City are two illustrations. An example of unethical behavior
involving two developed countries occurred in July 1980 when Dr. Martin J.
Cline, a member of the staff of the School of Medicine at the University of
California in Los Angeles, conducted the first gene therapy in humans on two
terminally ill thalassemia patients in Israel. Criticism of Dr. Cline by
American scientists came quickly after the procedure was announced, and it
focused on two issues. First, the insertion of combined genes into a patient
was not authorized by Dr. Cline’s protocol, nor was it envisaged under the
conditions of his grant. Second, the experiment itself was scientifically
premature and should have been preceded by more animal studies. In his defense,
Dr. Cline at first claimed that his experiment was not really novel, but later
(in a letter to the National Institutes of Health) he wrote: “I greatly regret
my decision to proceed with the DNA experiment. . . . I exercised poor judgment
in failing to halt the study.” Subsequently, most of the government funds for
research over which Dr. Cline had responsibility were withdrawn. One could argue on behalf of Dr. Cline
that because national cultures differ, their medical and ethical standards
should also. Why should medical research and treatment as practiced in the
industrial nations be mirrored in emerging, Third World, agricultural nations?
Should Western, Judeo-Christian values be promulgated in non-Western nations?
Is this not an example of cultural imperialism? Can one realistically require
individual free consent to participation in research when decisions in the
tribal community are basically communal and expressed through a single
spokesperson? Should a scientist be subject to penalty if he or she conducts
research forbidden in his or her own nation in another country? If the benefits
from a successful new treatment would be much greater in a country where the
disease is prevalent than in another where it is rare, cannot one rightly take
more risks in researching that treatment where the disease is prevalent? While the need for some form of
international guidelines has long been recognized, CIOMS first proposed a draft
in October 1980. After amendment by international participants at the numerous
CIOMS Roundtable Conferences, the guidelines were finally endorsed in October
1981 by the WHO Advisory Committee on Medical Research. They are consonant with
previous international codes and draw quite heavily upon recent American
Health, Education and Welfare and Health and Human Services regulations. The
new CIOMS international guidelines incorporate the two central aspects of all
contemporary national guidelines: the free and informed consent of the
participants and the prior scientific and ethical review of the research
protocols by an independent body of scientific experts and community
representatives. The central philosophic question of
whether differing national cultures should have different medical ethics is not
addressed by the CIOMS guidelines, but the answer is implied. The new
guidelines -- as did the Nüremberg Code and other declarations before them --
simply assume the basic Western humanist standards, particularly as they place
a high value on the welfare of the individual. If the authors of the guidelines
were asked to be self-conscious about their assumption, they might offer the
following justification: Western medicine has evolved with, and been motivated
by, Judeo-Christian and Greek values. Since it is the procedures of Western
medical research that are now being adopted throughout the world, the values
must go with them. It is doubtful that Western medicine would be effective
without the trust these values have elicited in patients. Only a few maverick
physicians, or a nation possessed by something as evil as Nazism, would
deliberately try to separate the procedures from the values. To this
justification, I would add my personal opinion that medical investigators
should be expected, wherever they work, to live up to their own personal beliefs
and to the spirit of at least their own national standards. Such behavior is
not imperialistic; it is just conscientious. Specifically the guidelines call for
research to be conducted by “appropriately qualified and experienced
investigators” who will describe their project in protocols outlining its
purpose, risks, proposed means of gaining consent, and position on
confidentiality. Children are to be included in research only if there can be
no substitutes for them. Pregnant women and mentally ill people must be
excluded unless the research relates to their particular status. Employees of
drug companies or dependent personnel such as medical students should not be
recruited if undue influence is involved. In a departure from the recent regulations
of most European nations, prisoners are permitted to be subjects. The guidelines do provide for some
flexibility in interpreting their standards according to available domestic
resources and social customs. This flexibility constitutes a recognition of the
differing cultural and ethical values obtaining between nations, but not an
abandonment of central Western standards. Thus, the consent of the subject may
in some developing countries be exercised by one or more representatives of the
community rather than by the individuals themselves. But such an exception to
the rule must be made only by those whose traditional role is to speak for and
to protect the welfare of the whole community. The process of review is to be conducted
by one or two independent review boards, depending upon availability of
resources. One “multidisciplinary advisory committee operative at the national
level” should have responsibility for assessing the safety and quality of all
new medicines and devices intended for use in their country. Another
recommendation is for an “Ethical Review Committee,” also interdisciplinary and
including community representatives, which would be responsible for evaluating
all foreign and domestic research protocols. The countries that don’t have many
trained medical-research personnel may have only a single board to perform both
of the above functions. The section on the task of ethical review
states that “an experiment on human subjects that is scientifically unsound is ipso
facto unethical.” In other words, bad science is bad ethics -- something we
Americans are still arguing about. Another element which is not yet included in
U.S. regulations is the requirement that compensation for injury received as a
result of participation in medical research is to be on a no-fault basis. In
America one still must go through the difficult process of suing for
malpractice before compensation can be gained. The promulgation of these international
guidelines is a major achievement, and Dr. Bankowski, and many others who
worked with him, deserve commendation. Although the guidelines obviously have
no mandatory power in themselves, they do provide reference points and goals
for individual governments to adopt, and they are also standards by which a
nation’s performance may be judged. One hopes that the new guidelines will
encourage the development of domestic medical review procedures where they are
presently inadequate, and that’ their publication will reveal and censure some
of the abuses caused by foreign exploitation. However, there are some technical
problems which these guidelines, and indeed current American ones, have not yet
resolved. If there is no consensus in an International Review Hoard or Ethical
Review Committee, does the minority have any right to appeal, and, if so, to
whom? A second problem is the monitoring of the conduct of research after the
protocol has been approved. Nobody in the United States does such monitoring on
a systematic basis, partly because it is a very time-consuming process and
partly because it is unpopular with the investigators, whose pride is hurt,
because it implies a lack of confidence in their continuing competence and
integrity. Another unresolved problem is how
research whose goal is the relief of diseases which occur primarily in Third
World countries is to be encouraged and funded. The poverty of many of these
nations precludes the funding of their own research, and drug companies have
understandably been reluctant to embark on such ventures because the potential
profits are not sufficient to cover the costs of development and marketing.
Perhaps all drug companies involved in international research should be
assessed dues which, along with donations from WHO, would help in subsidizing
such programs. Meanwhile, as an incentive to provide treatment as well, as
research, use of people as guinea pigs only should be prohibited. A related problem is that the CIOMS
guidelines do not clarify the issue of whether or not the same standards of
risks should obtain in a poorer country where a disease is prevalent as in the
funding country where the disease seldom occurs. On page six of the guidelines
appears a statement regarding the risks of research on new drugs in developing
countries: “Decisions relating to their investigation and subsequent use should
be made in the light of local judgment and experience, and directed to
practicable options rather than unobtainable ideals.” This recommendation
suggests that ethical leeway is intended in the degree of risk which is
acceptable in one community or nation as compared to another. However, on page
32, in a section of the guidelines titled “Externally Sponsored Research,” the
following statement is also made: “The ethical standards applied should be no
less exacting than they would be for research carried out within the initiating
country.” In my opinion a risk/benefit analysis should always be made, but
where a greater benefit is potentially available, a greater risk can be
ethically taken. Finally, the publication of international
guidelines for medical research illuminates the need for similar guidelines in
related fields. For instance, there is no internationally accepted minimum
standard for the labeling of pharmaceutical drugs. False claims and inadequate
warnings of dangers are common for drugs marketed in South America; the result
is often tragic. The export of toxic chemicals, particularly pesticides, to
developing countries without information regarding their dangers has, long been
a problem for them. If domestic, environmental and safety regulations require
the closing of an asbestos manufacturing plant in one country, on what moral
grounds can the moving of such a plant to another country be justified? Much has now been achieved in developing
standards for medical research around the world; now these standards need to be
applied. Much is still left to be done in the matter of international
regulation; those remaining tasks must now be addressed. |
