Brief Overview
Revised federal regulations put into effect in October
1996 allow certain human research activities to be conducted in
emergency settings. Most research in emergency settings falls under FDA regulations because it involves FDA regulated drugs, biologics, or devices (see 21
CFR Part 50), but non-FDA regulated research may fall under requirements almost identical to the FDA regulation (see OHRP guidance on Emergency Research Informed Consent Requirements).
UCSF researchers must carefully review these regulations
and their interpretation by the Committee on Human Research in
planning such research
and preparing applications for review by the CHR. (See also guidelines
on Surrogate Consent, Those
with Cognitive Impairments,
and Emergency Use and
Compassionate Use of Experimental Drugs and Devices for additional
information as appropriate.)
Background
These regulations are a result of years of considerable
and protracted debate at the national level about how to facilitate
potentially life-saving and life-enhancing research while protecting
the rights and welfare of subjects. They were developed with input
from a number of national organizations and physicians, including
those involved in the treatment of cardiac arrest, stroke, head trauma,
spinal cord injury, gunshot wounds, and poisoning.
The result of this national interest was that both the FDA and the
OPRR agreed that in very carefully controlled situations, research
may be allowed that includes subjects unable to consent for themselves
when more than minimal risk is involved.
Guidelines for implementing these regulations at UCSF continue to
be refined as investigators and the CHR gain more experience with
this process. The discussion below reflects the current regulations
and their interpretation by the CHR.

CHR Application Requirements
Researchers who wish to conduct research in an emergency
setting when there may be more than minimal risk but participation in the
research holds out the prospect of direct benefit to the subject should review
the regulations below very carefully to make sure that the proposed research
qualifies for a waiver of consent.
As noted above, most research in emergency settings ( and all such research that UCSF has reviewed as of February 2008) falls under FDA regulations because it involves FDA regulated drugs, biologics, or devices (see 21 CFR Part 50.24). However, non-FDA regulated research may fall under requirements almost identical to the FDA regulation (see guidance on Emergency Research Informed Consent Requirements), based on a waiver of applicability of sections of the DHHS regulations at 45 CFR 46. The DHHS requirements are essentially identical to the FDA regulations, and so the FDA regulations are quoted below. The DHHS guidance does state, however, that the DHHS waiver does not apply to research involving prisoners, fetuses, women, or in vitro fertilization. These restrictions are not included in the FDA regulation.
In addition, researchers are encouraged to consult with the CHR Chair and/or
CHR senior staff in preparing their applications. The following is a short
summary of the major points that will need to be considered carefully and
discussed in depth in the protocol in order to conduct the research:
1) Detailed Discussion in Protocol:
The issues raised in the sections and subsections of sections
50.24
(a) (1) through (5) below will need to be discussed and documented in the appropriate
sections of the protocol. The five points are summarized as follows: (a)
the human subjects are in a life-threatening situation, available treatments
are unproven or unsatisfactory, and the collection of valid scientific evidence
is necessary to determine the safety and effectiveness of particular interventions;
(b) obtaining informed consent is not feasible, for three reasons (see below);
(c) participation in the research holds out the prospect of direct benefit
to the subjects, for three reasons (see below); (d) the study could not practicably
be carried out without the waiver of informed consent; and (e) the study
defines the length of the potential therapeutic window and the investigator
has committed to attempting to contact a legally authorized representative
to ask for consent for each subject within that window of time. (Please note
that this detailed discussion will most likely necessitate that the protocol
extend beyond the usual ten-page limit.)
2) Community Consultation:
Consultation with appropriate community representatives will need to occur
before the research begins (see paragraph
50.24 (a)
(7) (i) below).
3) Public Disclosure:
Appropriate public disclosure will need to occur prior to the initiation
of the study as well at the completion of the study (see paragraphs
50.24
(a) (7) (ii) and (iii) below).
4) Ongoing Attempts to Obtain Consent:
Researchers planning to conduct research that does not include the informed
consent of all subjects must be committed to providing information and attempting
to obtain the consent from the subjects and/or the appropriate relatives
or legally authorized representatives on an ongoing basis throughout the
conduct of the research and at the conclusion of the research. Therefore,
several types of consent forms will need to be prepared in order to assure
that information is provided and that appropriate consent is obtained during
the various phases of the research. Please refer to the information above
in section G.6.b of this Appendix labeled Providing Subjects with
Additional Information and Types of Consent Documents Needed. In addition to the types
of consent forms discussed in the information above, it is also required
that information be provided about the clinical investigation to the subject's
legally authorized representative or to a relative, if feasible, if the subject
dies before consent has been obtained (see section
50.24
(b) below).
5) Summaries of Attempts to Obtain Consent:
Investigators will need to document and summarize their attempts to contact
family members to obtain their consent if obtaining informed consent is not
feasible and a legally authorized representative is not reasonably available.
This information will need to be submitted to the IRB at the time of continuing
review (see paragraph
50.24 (a) (7) (v) below).
6) A separate IND or IDE:
A separate IND or IDE will be needed (see section
50.24
(d) below).
7) Independent Data Monitoring Committee:
An independent data monitoring committee will need to be established (see
paragraph
50.24 (a) (7) (iv) below).

The
Regulations (21 CFR Part 50)
(See OHRP guidance on Emergency Research Informed Consent Requirements for research that is not regulated by the FDA. Provisions are essentially identical to the FDA regulation, with the exception noted above for research involving prisoners, fetuses, women, or in vitro fertilization.)
21 CFR 50.24 (a) The IRB responsible for the review, approval,
and continuing review of the clinical investigation described in this section
may approve that investigation without requiring that informed consent of
all subjects be obtained if the IRB (with the concurrence of a licensed physician
who is a member of the IRB and who is not otherwise participating in the
clinical investigation) finds and documents each of the following:
- The human subjects are in a life-threatening situation, available
treatments are unproven or unsatisfactory, and the collection of valid
scientific evidence,
which may include evidence obtained through randomized placebo-controlled
investigations, is necessary to determine the safety and effectiveness
of particular interventions.
- Obtaining informed consent is not feasible
because:
- The subjects will not be able to give their informed
consent as a result of their medical condition.
- The intervention under investigation must be administered before
consent from the subject's legally authorized representatives
is feasible; and
- There is no reasonable way to identify prospectively the individuals
likely to become eligible for participation in the clinical investigation.
- Participation in the research holds out the prospect of direct benefit
to the subjects because:
- Subjects are facing a life-threatening situation
that necessitates intervention;
- Appropriate animal and other preclinical
studies have been conducted, and the information derived from those
studies and related
evidence support
the potential for the intervention to provide a direct benefit to the individual
subjects; and
- Risks associated with the investigation are reasonable in
relation to what is known about the medical condition of the potential
class of subjects,
the risks and benefits of standard therapy, if any, and what is known about
the risks and benefits of the proposed intervention or activity.
- The clinical
investigation could not practicably be carried out without the
waiver.
- The proposed investigation plan defines the length of the potential
therapeutic window based on scientific evidence, and the investigator
has committed to
attempting to contact a legally authorized representative for each subject
within that window of time and, if feasible, to asking the legally authorized
representative contacted for consent within that window rather than proceeding
without consent. The investigator will summarize efforts made to contact
a legally authorized representative and make this information available
to the IRB at the time of continuing review.
- The IRB has reviewed
and approved informed consent procedures and an informed consent document.
These procedures and the informed consent document are
to be used with subjects or their legally authorized representatives in
situations where use of such procedures and documents is feasible. The
IRB has reviewed
and approved procedures and information to be used when providing an opportunity
for a family member to object to a subject's participation in the clinical
investigation consistent with paragraph (7)(v) below.
- Additional protections
of the rights and welfare of the subjects will be provided, including,
at least:
- Consultation (including, where appropriate, consultation
carried out by the IRB) with representatives of the communities
in which the clinical
investigation will be conducted and from which the subjects will
be drawn;
- Public disclosure to the communities in which the clinical investigation
will be conducted and from which the subjects will be drawn, prior to initiation
of the clinical investigation, of plans for the investigation and its risks
and expected benefits;
- Public disclosure of sufficient information following completion of
the clinical investigation to apprise the community and researchers of the
study, including the demographic characteristics of the research population,
and its results;
- Establishment of an independent data monitoring committee to exercise
oversight of the clinical investigation; and
- If obtaining informed consent is not feasible and a legally authorized
representative is not reasonably available, the investigator has committed,
if feasible, to attempting to contact within the therapeutic window the subject's
family member who is not a legally authorized representative, and asking
whether he or she objects to the subject's participation in the clinical
investigation. The investigator will summarize efforts made to contact family
members and make this information available to the IRB at the time of continuing
review.
50.24 (b) The IRB is responsible for ensuring that procedures are in place
to inform, at the earliest feasible opportunity, each subject, or if the
subject remains incapacitated, a legally authorized representative of the
subject, or if such a representative is not reasonably available, a family
member, of the subject's inclusion in the clinical investigation, the details
of the investigation and other information contained in the informed consent
document. The IRB shall also ensure that there is a procedure to inform the
subject, or if the subject remains incapacitated, a legally authorized representative
of the subject, or if such a representative is not reasonably available,
a family member, that he or she may discontinue the subject's participation
at any time without penalty or loss of benefits to which the subject is otherwise
entitled. If a legally authorized representative or family member is told
about the clinical investigation and the subject's condition improves, the
subject is also to be informed as soon as feasible. If a subject is entered
into a clinical investigation with waived consent and the subject dies before
a legally authorized representative or family member can be contacted, information
about the clinical investigation is to be provided to the subject's legally
authorized representative or family member, if feasible.
50.24 (c) The IRB determinations are to be retained by the IRB for at least
3 years after completion of the clinical investigation and the records accessible
for inspection by the FDA.
50.24 (d) Protocols involving an exception to the informed consent requirement
under this section must be performed under a separate investigational new
drug application (IND) or investigational device exemption (IDE) that clearly
identifies such protocols as protocols that may include subjects who are
unable to consent. The submission of those protocols in a separate IND/IDE
is required even if an IND for the same drug product or an IDE for the same
device already exists. Applications for investigations under this section
may not be submitted as amendments under 312.30 or 812.35 of this chapter.
50.24 (e) If an IRB determines that it cannot approve a clinical investigation
because the investigation does not meet the criteria in the exception provided
under paragraph (a) of this section or because of other relevant ethical
concerns, the IRB must document its findings and provide these findings promptly
in writing to the clinical investigator and to the sponsor of the clinical
investigation. The sponsor of the clinical investigation must promptly disclose
this information to FDA and to the sponsor's clinical investigators who are
participating or are asked to participate in this or a substantially equivalent
clinical investigation of the sponsor, and to other IRB's that have been,
or are, asked to review this or a substantially equivalent investigation
by that sponsor.
