Re: DHHS Notice of Proposed Recommendation Regarding Support of Research
Protocol: "Precursors to Diabetes in Japanese American Youth" Grant
Number I R01 DK59234-01
The proposed experiment
would involve 450 children healthy children, aged 8-10 years old,
300 of Japanese ancestry and 150 Caucasians. The experiment is not
approvable under federal regulations, 45 CFR 46 Subpart D because
it involves greater than minimal risk and no potential direct benefit
to the children.
Ethical
research involving human beings is predicated on the principles enshrined
in the Nuremberg Code and every subsequent code of medical research
ethics. Foremost among these principles is the inalienable right of
every human being to freely exercise his /her right to informed consent
to participate in medical research - or to refuse. Children,
however, are precluded from exercising legally valid informed consent
because of immaturity. This puts children in the category of non-consensual
human subjects who must depend on others to decide what serves their
best interest. The historical record amply documents
that children have suffered unduly in experiments not intended for
their benefit, that caused them pain and discomfort while putting
their welfare at risks of harm[1]
In 1983, federal regulations
were adopted for the purpose of protecting children from experiments
that might put them in harm's way, and to ensure that children will
not be exploited in experiments that are not in their best interest.
(45 CFR 46 Subpart D, sections 404-409) For example, under 45 CFR
46.405, "Research involving greater than minimal risk but presenting
the prospect of direct benefit to the individual subjects" is
permissible only if:
"the
relation of the anticipated benefit to the risk is at least as favorable
to the subjects as that presented by available alternative approaches."
Thus,
federal regulations require a higher standard of justification for
approval of pediatric research by setting limits on the level of risks
that children may be exposed to, and by restricting the inclusion
of children in non-therapeutic research (i.e. of no therapeutic benefit
to the individual child-subject).
45 CFR 46 Section 406:
"Research involving greater than minimal risk and no prospect of direct
benefit to individual subjects, but likely to yield generalizable
knowledge about the subject's disorder or condition."
Under section 46.406 research
may be conducted only if:
(a)
"the risk represents a minor increase over minimal risk; "the
intervention or procedurepresents experiences to subjects that are
reasonably commensurate with those inherent in their actual or expected
medical, dental, psychological, social, or educational situations;
(b)
"the intervention or procedure is likely to yield generalizable
knowledge about the subjects' disorder or condition which is of vital
importance for the understanding or amelioration of the subjects"
disorder or condition."
Thus, federal regulations
require that sufficient evidence must exist to lead researchers to
expect that the research "is likely" to provide "generalizable knowledge"
which is of "vital importance" for "the subjects' disorder or condition."
Section 407: "Research not otherwise approvable" may be approved only
after a two tier process of public review - by a panel of experts
and lay citizens - under the direct auspices of the Secretary of Health
and Human Services, approves it.
"Research not otherwise approvable which presents an opportunity
to understand, prevent, or alleviate a serious problem affecting the
health or welfare of children."
"the
Secretary, after consultation with a panel of experts in pertinent
disciplines (for example: science, medicine, education, ethics, law)
and following opportunity for public review and comment." [emphasis added]
Although the language of section 407 does
not provide clear guidance about the standards of justification, it
is a reasonable assumption that section 407 was not intended as an
"escape hatch" from regulatory restrictions protecting children.
Therefore, research "not
otherwise approvable" - i.e., because the risks may be greater than "minor increase over minimal risk," and / or the children are healthy and will, therefore, derive
no potential benefit - must meet scientific justification standards
that go beyond those required under sections 404, 405 and 406. Thus,
for a research project to be eligible under section 407, the IRB
must have sufficient evidence to believe that the proposed research
presents an exceptional opportunity to obtain vitally important knowledge
that is likely to lead to important information that will "prevent
or alleviate a serious problem affection the health and welfare of
children." [2]
The validity of our position,
namely, that the standards for approval under section 407 require
the investigators to meet a higher standard of justification, is demonstrated
by the fact that section 407 has been invoked only twice (perhaps,
3 times ?) since 1983, when federal protections for children were
adopted.(45 CFR 46 sections 404-408)
In 1992, a human growth
hormone (hGH) experiment on short children came under fire when the
Physician's Committee for Responsible Medicine (PCRM) petitioned NIH
to suspend the experiment.[3]
NIH responded by convening a panel of experts - essentially as
outlined in section 407 of 45 CFR 46 - to review the hGH trials.[4]
The panel's analysis, disagreements, and conclusions proved highly
problematic, particularly as the panel acknowledged a "paucity
of good data about the probability of risks and by the absence of
common measures of their significance."[5]
PCRM cited the following
risks which the panel did not address: cancer from increased liver
production of insulin growth factor, which is thought to increase
breast cancer; aggravated kidney problems in some children; metabolic
changes resulting in weight loss. Additionally, the panel failed
to give serious consideration to the psychological risks of recruiting
healthy children who do not have an actual physiologic, psychological,
or behavioral condition who are being treated as though they are "abnormal."[3] Nor did
they consider the diminished self-perception and shame felt by those
children who "failed" to grow as expected with the injections.
Another issue not addressed by the panel was the continued suspicion
of a possible link between hGH treatment and Creutzfeldt-Jacob Disease.[6]
Dr. Loretta Kopelman, a
co-chair of that panel of experts, has acknowledged that the panelists
"strongly disagreed" about basic elements of the issues. They disagreed
about whether three placebo injections a week constituted "minimal
risk, a minor increase over minimal risk, or greater" the psychosocial
risks of the study, or the impact of bringing children from early
childhood to late teens to NIH for a battery of physical and psychological
testing, including nude photographs.[7]
Critics have noted that
the panel of experts did not provide a reasoned rationale for conducting
the hGH trial. Thus, the panel's recommendation to continue the experiment
despite the uncertainties exacerbated the controversy. That public
controversy may have served as a deterrent for those who would invoke
section 207 today, to conduct risky experiments on children for hypothetical
benefits that cannot be measured. But the intrusion of financial
incentives for those who conduct experiments on children - including
a 6 month patent extension[8]
- has led the medical research community to accelerate the pace
of pediatric trials and to seek child subjects for potentially risky
experiments.[9]
Indeed, according to Dr.
Greg Koski, Director of the Office of Human Research Protection (OHRP),
during the year 2001, the Secretary of HHS received 26 requests for
section 207 review.[10] "Precursors to
Diabetes" appears to be the first of these 26 proposed pediatric research
projects under section 207 review to be publicly announced.
Specific aspects of the
proposed "Precursors to Diabetes" experiment:
The
(undated) "Report on Expert Panel Review Under Subpart D of 45 CFR
46" by an expert panel that was convened Aug 13-14, 2001, indicates
that the investigators claim that Asian adults have "a predisposition
to accumulate central, abdominal fat and have an increased risk for
type 2 diabetes" and that the risk is greatest "around puberty."
The study is purported to seek to "increase understanding about the
metabolic changes that precede the development of type 2 diabetes
in children and the influence of Asian ethnicity on the diabetes risk."
Armed
with nothing more than vague speculation about the possible influence
of "pubertal hormonal effects on glucose metabolism and insulin
resistance" on increased risk for type 2 diabetes, the investigators
would plan to conduct a battery of medical procedures on 8 to 10 year
old children. Some of the procedures involve unknown levels of risk
- such as x-ray techniques (Dual Energy X-Ray Absorptiometry)
and MRIs; some are invasive and painful - including blood draws
and intravenous glucose tolerance tests involving the insertion of an intravenous catheter and
infusion of glucose. And although children
have no say about their genetic privacy - nor will they profit from
genetic studies - their DNA will be collected "for future
genetic studies." The researchers claim their study will help
determine the influence of "both ancestry and pubertal hormone
effects" on developing type 2 diabetes.
- What solid
evidence is there to confirm that Asian adults have an ethnic "predisposition"
to diabetes?
- Should not
a survey be conducted first to find out about the true incidence
of diabetes in this population instead of just assuming that it
would be higher and, therefore, worthy of an invasive study?
- If an increased
incidence of diabetes in Asian adults exists, is there any evidence
that such predisposition can be detected in childhood, using the
tests described?
- Do the investigators
plan any intervention in children who test positive ?
Certain
diets have been shown to push adult onset diabetes into remission
(as well as contribute a host of other health benefits for children
and adults). Therefore, nutritional counseling - which requires no invasive,
uncomfortable screening tests - is a preferable alternative for
lowering the risks for diabetes if there is no superior treatment
or intervention other than dieting.
Maryland Court of Appeals
standard: "Best interest of the child"
We note with misgivings
that both the expert panel and OHRP administrators who recommend approval
of the pre-diabetes experiment, set aside the "best interest
of the child" standard - ignoring entirely the landmark
decision (Grimes v Kennedy Krieger Institute, 2001) by the Maryland
Court of Appeals.[11]
That decision undercuts the assumptions under which the biomedical
research community has approved and conducted nontherapeutic experiments
on children and other persons under a legal disability who suffered
as a result. The Court criticized the research community:
"The
researchers and their Institutional Review Board apparently saw nothing
wrong with the [re]search protocols that anticipated the possible
accumulation of lead in the blood of otherwise healthy children as
a result of the experiment, or they believed that the consents of
the parents made the research appropriate."[12]
Maryland's highest Court
rejected the self-serving utilitarian arguments made by a consortium
of research stakeholders who claimed such experiments are "critically
important" for the interest of children's health in general.
That Maryland Court decision
is entirely compatible with the federal regulations which recognize
the need to restrict the use of children in research that puts them
at risk. But the Court framed the ethical issues from the perspective
of law - not leaving any doubt about the distinction between research
that is therapeutic - intended to benefit the subject -
and research that is nontherapeutic - not intended to benefit the individual
child. The Court left no room for linguistic calisthenics or semantic
deconstruction, ruling that children have a right to be protected
from experiments involving risks without a benefit for them. And
the Court held that parents, researchers and institutions could be
held accountable if they violate the legal standard of protecting
"the best interest of the individual child."
Since nontherapeutic research
presents the inherent possibility of harm, such research is not in
the best interest of a child. The Maryland Court concurred with a
1995 decision by the New York State Supreme Court[13]
which held that parents who might want to volunteer themselves for
research lacked legal authority to volunteer their children for nontherapeutic
research. To underscore the non-transferability of the right to informed
consent to research, the New York Court held that parents have no
right "to make martyrs of their children before they have reached
the age of full and legal discretion when they can make that choice
for themselves."
The Maryland Court put
it this way:
"It is not in the best
interest of a specific child, in a nontherapeutic research project,
to be placed in a research environment, which might possibly be, or
proves to be, hazardous to the health of the child. We have long
stressed that the best interest of the child is the overriding concern
of this Court in matters relating to childrenŠIt is, simply, and we
hope, succinctly put, not in the best interest of any healthy child
to be intentionally put in a nontherapeutic situation where his or
her health may be impaired, in order to test methods that may ultimately
benefit all children."[14]
In both cases, the Court
stepped in because it was obvious to the Court that children -
and other vulnerable persons who are legally disabled - were
being exploited and those charged with overseeing the conduct of research
and the approval process failed to protect them from experiments that
are against their best interest. The Court held that such disadvantaged
individuals may not be used in non-therapeutic experiments if there
is "any risk or injury or damage to the healthy of the subject."[15]
The Maryland Court admonished
the research community:
"[I]t is clear to
this court that the scientific and medical communities cannot be permitted
to assume sole authority to determine ultimately what is right and
appropriate in respect to research projects involving young children."[16]
Indeed, the 1994 Report
by the Advisory Commission on Human Radiation Experiments (ACHRE)
report noted that if judged by the standards used at the time the
radiation experiments were conducted, the 21 discredited radiation
experiments identified by ACHRE in which children were put at increased
risk of cancer, passed the researchers' standards. It is doubtful
they would have been approved had a sizable number of members of the
public served on the committees that approved them.
From the information provided
by OHRP it is evident that the "Precursors to Diabetes"
experiment does not even come close to meeting the ethical standards
required for approval under federal regulations. Without access to
the actual protocol, we can only infer from the expert panel's report,
and from letter of determination suspending a similar pre-diabetes
screening experiment at the National Institute for Child and Human
Development,[17] that the risks
for the 450 children are not justified by any claimed projected future
benefit.
First, there is no evidence
that that the children sought for recruitment are at real risk of
diabetes. Second, there is no evidence
to demonstrate that the research meets the "best interest of
the child" standard - nor is there convincing evidence that it
is "likely to yield generalizable knowledge" which is of
"vital importance" that will help to "prevent, or alleviate
a serious problem affecting the health and welfare of children."
Indeed, the panel's report indicates that one of the expert panel
members dissented from the panel's recommendation, and did not recommend
approval.
The dissenting expert indicated
that the "Precursor to Diabetes" experiment had "serious design flaws"
and "will yield little, if any, knowledge about the problem it intends
to address." This expert's opinion is that "the study would yield
little, if any, reliable information that would help to better understand,
prevent, or alleviate the serious problem of type 2 diabetes in children."
Furthermore, this expert concluded: "only one subject [out of 450]
would ultimately become diabetic."
From the information available
to us, it is apparent to The Alliance for Human Research Protection
that "Precursors to Diabetes in Japanese American Youth"
fails to comply with the fundamental ethical standards of justification
for conducting human experiments:
- "results for the
good of society that are unprocurable by other methods or means
of study." (Nuremberg Code, emphasis added);
- designed to yield generalizable knowledge that
meets the standard of "vital importance." (45 CFR 46.406)
- "best interest of the
child" (Maryland Court of Appeals)
We are concerned that the
federal agency whose mission is to enforce federal regulations and
protect human subjects - including children - is using its authority to
encourage an experiment that will expose healthy children to undue
risks of harm. The experiment appears to be a "fishing expedition"
whose value is in doubt even by experts.
We believe that children
should not be exposed to pain, discomfort and potential risks of harm
in experiments, particularly when there is a high degree of scientific
uncertainty about the knowledge to be gained from such experiments - unless
the research is intended to provide treatment for a serious condition
that the children actually have. This experiment appears to mirror
the ethical and scientific flaws that were apparent in the growth
hormone experiment: "paucity of good data about the probability
of risks and by the absence of common measures of their significance."[3]
By recommending approval of this experiment, the expert panel and
OHRP are defying the Maryland Court ruling.
It is of note that pediatricians
and primary care physicians consulted by AHRP concur with the Court's
protective stance toward children. They reject the claims made by
certain research stakeholders that assume that all children
are "at risk" of one or another "condition" or
"disorder." A hypothetical risk does not provide the justification
for exposing healthy children to greater than minimal risk, not to
mention pain and discomfort, in experiments that seek to identify
a miniscule percentage of children who may be "at risk"
of the condition being studied.
The process by which "Precursors
of Diabetes" has been reviewed most importantly, the abridged,
almost non-existent period provided for public review was neither
transparent, nor in compliance with the spirit of the existing federal
regulations. How else can DHHS explain the fact that the expert panel
convened Aug 13-14, 2001 and a year later, the public announcement
provided a mere two-week window for
review and comment in the month of August?
Any decision to conduct
medical experiments "not otherwise approvable" on children
challenges the moral principles of our society, and will have impact
on the health and well-being of children. It requires, therefore an
adequate period "for public review and comment" - which
has not been provided.
We ask the following:
1)
Online access to the research protocol and consent documents.
2)
Public disclosure of the names and affiliations of panel members
who should be required to make a declaration about possible conflicts
of interest.
3)
Each panel member's review should be publicly available online.
4)
Proposed 407 rulings should be advertised for greatest public
access: Reuters Health;
PubMed News; American Medical News; Associated Press; Chronicle of
Higher Education; WebMD; Health Freedom Watch; Public Health Reports;
American Family Physician; Informed Parent are some appropriate publications.
5)
A three-month period for public review and comments should
be provided.
6)
Online publication of all the comments received.
7)
Review by Office of Inspector General's legal staff with publication
of their opinion regarding how this research approval complies with
existing federal regulations.
