DEPARTMENT OF HEALTH AND HUMAN SERVICES
Draft Guidance on Disclosing Reasonably Foreseeable Risks in
Research Evaluating Standards of Care
AGENCY: Office of the Secretary, Office of the Assistant Secretary for
Health, Office for Human Research Protections, Department of Health and
Human Services (HHS).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Department of Health and Human Services (HHS), through the
Office for Human Research Protections (OHRP) is announcing the
availability of a draft guidance for the research community entitled
``Guidance on Disclosing Reasonably Foreseeable Risks in Research
Evaluating Standards of Care.'' OHRP is specifically addressing what
risks to subjects are presented by research evaluating or comparing
risks
[[Page 63630]]
associated with standards of care, and which of these risks are
reasonably foreseeable and should be disclosed to prospective research
subjects as part of their informed consent. OHRP is soliciting written
comments from all interested parties, including, but not limited to IRB
members, IRB staff, institutional officials, research institutions,
investigators, research subject advocacy groups, ethicists, the
regulated community, and the public at large. This draft guidance
represents OHRP's current thinking on this topic.
Certain treatments and procedures that are commonly used in health
care for a given type of disease or condition have come to be known as
``standards of care.'' Multiple ``standards of care'' involving widely
differing treatments and risks may be available for the same disease or
medical condition. Where multiple ``standard of care'' options are
available for a given disease or condition, the use of the term does
not imply that the options will produce similar benefits or incur
similar risks. Furthermore, patients may not find those options equally
acceptable, nor do physicians always use them interchangeably.
Importantly there is not necessarily a limit on how different the risks
from two versions of a standard of care might be. For example, it may
already be known that one of those versions imposes a significantly
higher risk of death than the other.
Adequate knowledge about the effectiveness and risks of standards
of care and how these standards compare to each other is sometimes
lacking. In recent years research studies designed to evaluate such
treatments and procedures have become commonplace. These studies are
often called ``comparative effectiveness research'' or ``standard of
care research.''
As this type of research has become more common, so too have
questions about how the HHS human subject protection regulations (45
CFR part 46) apply to such research. There is uncertainty in the
research community about which risks of the research should be
determined to be reasonably foreseeable risks of research and how they
should be described to prospective subjects in the process of informed
consent. OHRP's interpretation of the HHS research regulations has been
that if people are being asked to undergo procedures in a research
study that involve risks that they would not otherwise be exposed to,
these are `research risks' that people must be informed about. Only in
that way are they able to make a truly informed decision about whether
they are willing to participate. For comparative effectiveness or
standard of care research, OHRP's general position is that the
reasonably foreseeable risks of research include already-identified
risks of the standards of care being evaluated as a purpose of the
research when the risks being evaluated are different from the risks
subjects would be exposed to outside of the study. This guidance
addresses these issues in the form of frequently asked questions. OHRP
will consider comments received before issuing the final guidance
document.

SUPPLEMENTARY INFORMATION:
I. Background
A. HHS Protection of Human Subjects Regulations
HHS, through OHRP, regulates research involving human subjects
conducted or supported by HHS. The HHS human subjects protection
regulations pertain to several different entities, including the
institutional review board (IRB) charged with reviewing non-exempt
human subjects research.
The IRB is an administrative body that takes the form of a board,
committee, or group, and is responsible for conducting the initial and
continuing review of research involving human subjects. The IRB must
have authority to approve, require modification of (in order to secure
approval), or disapprove all research activities regulated by HHS as
required by 45 CFR 46.109(a). An IRB's primary purpose in reviewing
research is to ensure the protection of the rights and welfare of human
research subjects. In order to approve research, an IRB is required to
make certain determinations, including that the following 46.111(a)(2)
criterion is met:
Risks to subjects are reasonable in relation to anticipated
benefits, if any, to subjects, and the importance of the knowledge
that may reasonably be expected to result. In evaluating risks and
benefits, the IRB should consider only those risks and benefits that
may result from the research (as distinguished from risks and
benefits of therapies subjects would receive even if not
participating in the research).
The HHS human subjects protections regulations further require that
an investigator must obtain informed consent from research subjects
prior to the subjects' participation in the research, unless this
requirement is waived by the IRB. In this informed consent process, the
subjects must be provided with ``a description of any reasonably
foreseeable risks or discomforts to the subject'' as required by
46.111(a)(4) and 46.116(a)(2).
B. OHRP's Compliance Oversight Investigation of SUPPORT
On March 7, 2013, OHRP issued a compliance oversight determination
letter regarding its investigation into ``The Surfactant, Positive
Pressure, and Oxygenation Randomized Trial'' (SUPPORT) (http://www.hhs.gov/ohrp/detrm_letrs/YR13/mar13a.pdf). OHRP determined that
certain risks related to the interventions being studied in the SUPPORT
trial were required by 45 CFR part 46 to be disclosed to the research
subjects, and that the subjects were not informed of these risks.
OHRP's view of the SUPPORT trial, as described in this determination
letter, triggered extensive public discussion regarding (1) what risks
to subjects are presented by clinical trials studying interventions
that are standards of care in the clinical
[[Page 63631]]
treatment context, such that an IRB must evaluate those risks in
relation to the anticipated benefits of the research; and (2) how an
IRB should assess whether those risks are reasonably foreseeable such
that the risks must be described to prospective subjects as part of
obtaining a person's informed consent.
The critical disagreement in the research community relates to the
issue of what risks must be disclosed to prospective subjects in a
research study where participants will be receiving a treatment that is
different from the treatment they would have received outside the
study, but still within the range of ``standard of care'' that some
doctors use for clinical purposes. Multiple ``standards of care''
involving widely differing treatments and risks may be available for
the same disease or medical condition. Where multiple ``standard of
care'' options are available for a given disease or condition, the use
of the term does not imply that the options will produce similar
benefits or incur similar risks. Furthermore, patients may not find
those options equally acceptable, nor do physicians always use them
interchangeably. Importantly there is not necessarily a limit on how
different the risks from two versions of a standard of care might be.
For example, it may already be known that one of those versions imposes
a significantly higher risk of death than the other.
In the SUPPORT trial, an infant had a 50% chance of being assigned
to the ``lower oxygen'' arm (where the oxygen saturation percentage
would be maintained between 85% and 89%) or the ``higher oxygen'' range
(between 91% and 95%). The level of oxygen the infants received was
chosen by randomization. This design was intended to move these infants
far enough away from the center value (90%), so that the differences in
the amount of oxygen the two groups received would allow detection of
different health outcomes in the groups. Therefore, for the great
majority of infants in the trial, it is likely that their participation
altered the level of oxygen they received compared to what they would
have received had they not participated. Some in the research community
maintain that because the lower (85% to 89%) and higher (91% to 95%)
ranges of oxygen saturation provided to the infants were within the
standard of care range, there were no known risks to participants in
the study from being randomized to these two oxygen saturation levels.
OHRP disagrees with this perspective, and maintains that the key issue
is that the treatment and possible risks infants were exposed to in the
research were different from the treatment and possible risks they
would have been exposed to if they had not been in the trial, not that
the treatment provided in the trial was within the standard of care.
OHRP's interpretation of the research regulations has been that, if a
person in a research study is being asked to undergo procedures that
involve reasonably foreseeable risks that they would not have otherwise
been exposed to, then that person needs to be told about those risks.
Only in this way can people make a truly informed decision about
whether they are willing to participate.
OHRP has become aware, through the public reaction to OHRP's
determination letter, of differing perspectives in the scientific,
research, and ethics communities about these issues and how the
relevant requirements of the HHS protection of human subjects
regulations should apply to research studying standard of care
interventions. This draft guidance is intended to clarify how to apply
the HHS regulations at 45 CFR part 46 to studies that are designed to
evaluate one or more standards of care.
C. Public Meeting
On August 28, 2013, a public meeting was held at the HHS Hubert H.
Humphrey Building to provide an opportunity for broad public
participation and public comments concerning how the HHS human subjects
protections requirements should be applied to research studying one or
more interventions which are used as standard of care treatment in the
non-research context. HHS specifically requested input regarding how an
IRB should assess the risks of research involving randomization to one
of more standard of care interventions, and what reasonably foreseeable
risks of the research should be disclosed to research subjects in the
informed consent process. The public meeting and comments were intended
to assist OHRP in developing guidance regarding what constitutes
reasonably foreseeable risk in research involving standard of care
interventions such that the risk is required to be disclosed to
research subjects. There were 27 oral presentations at the public
meeting and 72 written comments submitted during the open comment
period of June 26, 2013 through September 9, 2013.
The meeting was conducted by HHS officials, including the Director
of OHRP. The meeting was reserved for presentations of comments,
recommendations, and data from presenters. The time for each
presentation was 7 minutes. The allocation of time was based on the
number of registered presenters. Presenters were scheduled to speak in
the order in which they registered. Only HHS panel members questioned
presenters during or at the conclusion of their presentation. The
meeting was recorded and transcribed. The recording and transcription
are accessible through the OHRP Web site, http://www.hhs.gov/ohrp/newsroom/rfc/Public%20Meeting%20August%2028,%202013/aug28public.html.
In addition to materials submitted for discussion at the public
meeting, individuals were offered the opportunity to submit other
written comments after the public meeting. All submitted comments were
considered by HHS during the guidance development phase. A discussion
of the public comments is below.
II. Discussion of Public Comments
HHS invited comments at the public meeting regarding how an IRB
should assess the risks of research involving randomization to one or
more standard of care interventions, and which research risks should be
disclosed to subjects in the informed consent process. HHS was
specifically interested in public input on the following questions:
1. How should an IRB assess the risks of standard of care
interventions provided to subjects in the research context?
a. Under what circumstances should an IRB consider those to be
risks that may result from the research?
b. Under what circumstances should an IRB refrain from considering
those risks as unrelated to the research?
c. What type of evidence should an IRB evaluate in identifying
these risks?
Several commenters presented arguments for always disclosing
standard of care risks to potential subjects of a clinical trial. Many
felt that all risks, including those of the standard of care, must be
disclosed in order to allow subjects and parents of subjects to make a
fully informed choice to participate in research. Some expressed the
view that the risks of standard of care interventions are magnified
when incorporated into a clinical trial, and to mitigate the potential
harms these commenters recommended mandating data safety monitoring
plans to detect and identify perceived reasonable foreseeable risk. The
outcome measures produced from data safety monitoring plans would
identify the reasonably foreseeable risks of the research.
Opposing arguments were expressed against incorporating standard of
care
[[Page 63632]]
risks for clinical intervention as risks of standard of care or
comparative effectiveness research. Many commenters stated that it is
inaccurate to describe standard of care intervention risks as research
risks, and that good evidence of such risks is often lacking; they
pointed out that many widely used medical practices are based on
clinician judgments alone. Proponents of this view expressed the
opinion that IRBs should not require standard of care risks to be
disclosed as research risks, but rather, indicated that standard of
care inventions should be addressed in the clinical treatment consent
prior to enrolling potential subjects in the clinical trial.
Response: OHRP agrees that to the extent participation in a
clinical trial does not impose risks that are different from those to
which a subject would have been exposed had they not been in the trial,
those risks should not be considered risks attributable to the
research. The key issue is not whether an intervention provided to
subjects is within a standard of care, but whether the treatment a
subject receives (and thus the risks they are exposed to) is different
from that which these subjects would have been exposed to outside of
the research study. The risks that result from such a difference in
treatment are risks derived from participation in the research study.
Patients randomized to different standards of care in a comparative
effectiveness trial should accordingly be made aware of the risks of
the standards of care that are being compared. OHRP agrees that the
distinction between receiving clinical care and participating in
research must be made clear to subjects.
2. What factors should an IRB consider in determining that the
research-related risks of standard of care interventions, provided to
research subjects in the research context, are reasonably foreseeable
and therefore required to be disclosed to subjects?
Many commenters recommended first defining the term ``standard of
care'' prior to defining the term ``reasonably foreseeable risk.''
Various commenters stated that the term ``standard of care'' is used to
refer to a medically recognized standard of care that has been accepted
by medical experts as a proper treatment or procedure for a given
disease or condition, and been widely used by healthcare professionals.
These commenters pointed to the need for an evidentiary basis for a
given standard of care, and felt that whether it was acquired through
publication, through conduct of randomized clinical trials, or through
expert opinion, the basis for assessing standard of care may vary
throughout the medical community, and therefore the research and other
evidence regarding the associated risks of a standard of care being
evaluated may vary as well.
The varying definitions for ``reasonably foreseeable risk''
presented in the comments were representative of the lack of consensus
of the interpretation of the term among the experts in the medical and
clinical research community.
Several commenters identified a number of kinds of standards and
quantitative measures to help define reasonably foreseeable risks. The
proposed levels of evidence offered by the commenters included clinical
trial evidence, peer and literature review analysis, professional prior
experience, risk and benefit ratio analyses and baseline risks of the
identified population. A few commenters expressed the view that
reasonably foreseeable risks are those risks supported in peer reviewed
medical literature that occur in 5% of the patients or that hold p-
values of less than 0.10 in one or more trials.
One comment stated, ``events for which one can hypothesize a
plausible risk but which have not been shown to be caused by the
intervention should not be classified as reasonably foreseeable.''
Other commenters were opposed to attempting a suggested definition.
There was an overall agreement among the commenters about
disclosing research risks of standard of care treatment to the
prospective participants, but disagreement on where in the informed
consent document this information should be disclosed.
Response: OHRP believes that all research and other evidence
underlying medically recognized standards of care should be given
appropriate consideration in determining whether risks are reasonably
foreseeable. The draft guidance does not address specific quantitative
approaches to evaluating or identifying reasonably foreseeable risk.
With regard to which risks should be considered ``reasonably
foreseeable,'' OHRP concluded that at a minimum, identified risks
associated with a standard of care that are being evaluated as a
purpose of the research, should certainly be considered ``reasonably
foreseeable.'' A core purpose of the Common Rule is to allow
prospective subjects to make informed decisions about whether to
participate in research. If a specific risk has been identified as
significant enough that it is important for the Federal government to
spend taxpayer money to better understand the extent or nature of that
risk, then that risk is one that prospective subjects should be made
aware of so that they can decide if they want to be exposed to it. It
would be seem inappropriate to have both the federal agency funding a
study and the researchers conducting it aware of an identified risk,
and yet not disclose that risk to the very subjects who would be
exposed to it, while at the same time claiming that their ``informed''
consent to participation has been obtained in a very meaningful way.
3. How should randomization be considered in research studying one
or more interventions within the standards of care? Should the
randomization procedure itself be considered to present a risk to the
subjects? Why or why not? If so, is the risk presented by randomization
more than minimal risk? Should an IRB be allowed to waive informed
consent for research involving randomization of subjects to one or more
standard of care interventions? Why or why not?
Many commenters felt that randomization alone does not pose a
research risk, while others disagreed. In certain instances, some
commenters said that randomization can impose harms to research
subjects. One commenter stated that ``if a research study involves
random assignment of two different interventions that are sometimes
used for treating an acute stroke, and death and neurological
impairment are the primary endpoints being measured in the study, such
research should be considered to present much greater than minimal risk
to subjects.'' A subset of commenters expressed that such outcomes
should be made clear in the informed consent process and document. One
commenter stated ``research involving randomization to one or more
standard of care interventions should follow the same requirements for
informed consent as other research studies and should not be assumed to
involve no more than minimal risk.''
Some commenters recommended that clinical trials involving
randomization should not be permitted to waive informed consent for
subjects involving standard of care interventions. One commenter
suggested that the use of randomization with waiver of consent deprives
subjects of the trust inherent in the doctor-patient relationship.
A small subset of commenters cited the loss of autonomy of the
research participant by incorporating randomization in a protocol. When
people are randomly assigned to one of a number of different standards
of care, they forego the ability to choose which standard of care they
prefer.
[[Page 63633]]
However, other comments indicated that consent could be waived for
standard of care trials. One commenter stated, ``waivers of consent for
randomization are appropriate, ethically defensible and necessary in
the case of comparing two standards of care interventions in some
cases'' and that ``waiving consent requires active and innovative ways
to engage the community and reach patients.''
In addition to the ethical defensibility for waiver of consent, one
commenter expressed that there is nothing inherent in randomization
that should preclude consideration of a waiver. ``Most research
involving prospective randomization seems likely to require informed
consent; because it seems unlikely that the research would meet the
46.116 requirement that the IRB finds that the research couldn't
feasibly be carried out without a waiver of consent. However, the IRB
should be allowed to waive informed consent for any research that does
meet all the waiver criteria.''
Others comments stressed that waiver of consent does not eliminate
the duty to communicate with the research participant about the risks
and benefits of a study. A few commenters expressed that potential
research participants should be informed of randomization but that
there is no reasonable evidence that randomization increases risk.
However, the lack of evidence regarding the risk of randomization does
not justify the use or prohibition of waiver of informed consent.
Response: The draft guidance treats randomization no differently
than any other mechanism by which a research subject may be assigned to
a particular treatment. The underlying question, as discussed above, is
whether, in the study, a subject will be assigned to a treatment whose
risks may be different from the risks they would have been exposed to
outside of the trial. If that happens--whether it is by randomization
or some other study design (e.g., all of the subjects could be assigned
to the same treatment, with no randomization at all)--then those
differences in risks are risks relating to participating in the
research. Thus, in this sense, there are no ``special'' or unique risks
to randomization. The thing that matters is whether participating in
the study may expose a subject to risks that are different from those
they would otherwise have been exposed to.
4. How, and to what extent, does uncertainty about risk within the
standard of care affect the answers to these questions? What if the
risk significantly varies within the standard of care?
One commenter stated that the fact that there is uncertainty about
differences in the proposed primary and secondary outcomes between two
or more groups receiving different interventions being tested in a
clinical trial is one reason that such research involves foreseeable
risks to the subjects. If there were no such uncertainty, there would
be no reasonable basis for conducting the research in the first place,
and it would be unethical to do so. Others felt that uncertainty alone
does not affect the risks of standard of care research to a research
subject because risks of the standard of care do not affect research
risk, regardless of the magnitude or certainty of the risks of the
standard of care.
Other comments in this area addressed models for research risk
disclosure, such as a transparency model in which investigators would
``explain to potential research participants what scientists and
physicians think they know, commonly believe and the basis for such
knowledge and beliefs.''
Response: The draft guidance does not address the issue of
uncertainty of risk associated with standard of care or comparative
effectiveness research overall. However, the guidance does indicate
that when one of the purposes of the research is the evaluation or
comparison of risks associated with standards of care, and the risks of
the standard of care received by the subjects are different from those
risks the subjects would be exposed to outside of the research, then
these risks should be considered to be reasonably foreseeable.
5. Under what circumstances do potential risks qualify as
reasonably foreseeable risks? For example, is it sufficient that there
be a documented belief in the medical community that a particular
intervention within the standard of care increases the risk of harm, or
is it necessary that there be published studies identifying the risk?
Comments focused on methods to evaluate and identify reasonably
foreseeable risks, and recommended that the phrases ``reasonably
foreseeable'' and ``all imaginable'' risks need to be clarified among
the research community. To assist, one commenter recommended that a
body of annotated examples, analogous to case law, needed to be created
for IRBs to use as precedent to evaluate clinical trials. Another
commenter recommended that IRBs need experts who can evaluate the
actual risks to subjects.
Several comments recommended various criteria for identifying
reasonably foreseeable risks, such as credible evidence, reported
safety concerns, and ``significant documented belief'' in the medical
community that a particular intervention would increases the risk of
harm. Other comments added biological plausibility and clinical
experience as qualifiers. All submitted comments concurred with the
need to further evaluate the determination of reasonably foreseeable
risk.
Response: As discussed above, the guidance concludes that if
evaluating a particular risk associated with a standard of care is a
purpose of the research, then in general that particular risk should be
considered to be ``reasonably foreseeable.'' Reasonably foreseeable
risks must be disclosed as risks in the informed consent process in
accordance with the regulatory requirements of 45 CFR 46.116(a)(2).
OHRP recognizes that the available evidence regarding the risks of
specific standards of care will vary, and may include evidence from one
or more clinical trials, other research studies, the opinion of
clinical experts, and the history of clinical practice, all of which
are taken into account in the formulation of standard of practice
guidelines. In any case, if a particular identified risk is considered
significant enough to constitute a rationale for conducting the study,
then this should in almost all cases imply the conclusion that the risk
is ``reasonably foreseeable'' for the purposes of these regulations,
and that it would be mistaken to claim that informed consent was
obtained if prospective subjects were not made aware of that risk.
General Comments
Some commenters expressed views not directly related to the
questions asked by OHRP. Specifically, several commenters made remarks
directly related to the SUPPORT trial. In addition, other issues of
concern focused on cluster randomization, consent waivers based on the
research's potential for public health benefit, and rigorous research
evaluations. Although the commenters disagreed with specific aspects of
these topics, they agreed that these issues are growing concerns among
the research community and should be discussed further.
