Transcript and Presenter's Notes

Title: Protecting Human Research Participants


1
Protecting Human Research Participants
  • Dr. Rasha Salama
  • PhD Community Medicine and Public Health
  • Suez Canal University
  • Egypt

2
Research
  • Research is the systematic collection, analysis
    and interpretation of data to answer a certain
    question or solve a problem

3
What is Research About?
  • Discover knowledge
  • (research)
  • Transfer knowledge
  • (education, publication)
  • Apply knowledge
  • (translation, outreach extension to the
    community welfare)

4
Contribution of Research
  • Research can contribute to the
  • Researcher
  • Individual level (patient)
  • Community at large

5
Protection of Research ParticipantsWho and What?
  • Who should be involved?
  • Individuals involved in the design and/or conduct
    of human subjects research.
  • What is the purpose?
  • Preparation of investigators involved in the
    design and/or conduct of research involving human
    subjects to understand their obligations to
    protect the rights and welfare of subjects in
    research.

6
Goals and Principles of Human Subjects Protection
  • Human subjects are essential to the conduct of
    research intended to improve human health. As
    such, the relationship between investigators and
    human subjects is critical and should be based on
    honesty, trust, and respect.

7
Historical Events Nazi Medical War Crimes
(19391945)
  • The experiments conducted by Nazi physicians
    during World War II were unprecedented in their
    scope and the degree of harm and suffering
  • Medical experiments were performed on thousands
    of camp prisoners and included deadly studies and
    tortures such as injecting people with gasoline
    and live viruses, and forcing people to ingest
    poisons.
  • In December 1946, the War Crimes Tribunal at
    Nuremberg indicted 20 physicians and 3
    administrators because they hadcorrupted the
    ethics of the medical and scientific professions
    and repeatedly and deliberately
  • violated the rights of the subjects

8
Historical Events The Nuremburg Code
  • In the August 1947 the judges included a section
    called Permissible Medical Experiments.
  • This section became known as the Nuremberg Code
    and was the first international code of research
    ethics.
  • This set of directives established the basic
    principles that must be observed in order to
    satisfy moral, ethical, and legal concepts in the
    conduct of human subject research.

9
The Nuremburg CodeTEN directives for human
experimentation
  • 1. Voluntary consent of the human subject is
    absolutely essential
  • 2. The experiment must yield generalizable
    knowledge that could not be obtained in any other
    way and is not random and unnecessary in nature
  • 3. Animal experimentation should precede human
    experimentation
  • 4. All unnecessary physical and mental suffering
    and injury should be avoided
  • 5. No experiment should be conducted if there is
    reason to believe that death or disabling injury
    will occur

10
The Nuremburg Code (cont.)TEN directives for
human experimentation
  • 6. The degree of risk to subjects should never
    exceed the humanitarian importance of the problem
  • 7. Risks to the subjects should be minimized
    through proper preparations
  • 8. Experiments should only be conducted by
    scientifically qualified investigators
  • 9. Subjects should always be at liberty to
    withdraw from experiments
  • 10. Investigators must be ready to end the
    experiment at any stage if there is cause to
    believe that continuing the experiment is likely
    to result in injury, disability or death to the
    subject

11
The Syphilis Study at Tuskegee
  • .
  • Study of the natural history of untreated
    syphilis (1930-1972)
  • involved approximately 600 African-American men
    about 400 with syphilis (cases) and about 200
    without syphilis (controls). These men were
    recruited without informed consent and were led
    to believe that some of the procedures done in
    the interest of research (e.g., spinal taps) were
    actually special free treatment.
  • In the 1940s, penicillin was found to be
    effective in the treatment of syphilis. The
    Syphilis Study at Tuskegee continued, however,
    and the men were neither informed about nor
    treated with the antibiotic.
  • By 1946, reports indicated that the death rate
    among those with syphilis was about twice as high
    as it was among the controls.

12
Outcomes of the Syphilis Study at Tuskegee
  • Outcomes included
  • National Research Act of 1974
  • Department of Health and Human Services (HHS)
    Policy for Protection of Human Subjects
  • National Commission for the Protection of Human
    Subjects of Biomedical and Behavioral Research

13
The Belmont Report
  • The Belmont Report
  • identified three principles
  • essential to the
  • ethical conduct of
  • research with humans
  • Respect for persons
  • Beneficence
  • Justice
  • These three basic principles serve as the
    foundation of the current HHS regulations and
    guidelines for the ethical conduct of human
    subjects research supported by HHS.

14

1. Respect for Persons
15
1. Respect for Persons
  • The principle of respect for persons can be
    broken down into two basic ideas
  • 1. Individuals should be treated as autonomous
    agents
  • An autonomous person is able to
  • Consider the potential harms and benefits of a
    situation
  • Analyze how those risks and potential benefits
    relate to his or her personal goals and values
  • Take action based on that analysis

16
1. Respect for Persons (cont.)
  • 2. Persons with diminished autonomy are
    entitled to additional protections
  • Special provisions may need to be made when an
    individuals comprehension is severely limited or
    when a class of research participants is
    considered incapable of informed decision making
    (e.g. children, people with severe developmental
    disorders, or individuals suffering from
    dementias).
  • In some cases, respect for persons may require
    seeking the permission of other parties, such as
    a parent or legal guardian.

17
Challenges
  • The challenges in applying the Belmont
    principle of respect for persons are in
  • Making sure that potential participants
    comprehend the risks and potential benefits of
    participating in research
  • Avoiding influencing potential participants
    decisions either through (coercion) or through
    (undue influence)

18
Coercion
  • Influencing an individual decision about
    whether or not to do something by using explicit
    or implied threats (loss of good standing in job,
    poor grades, etc.)

19
Undue Influence
  • An offer of an excessive, unwarranted,
    inappropriate, or improper reward or other
    overture in order to obtain compliance
    excessive compensation
  • Undue inducements are troublesome because
  • offers that are too attractive may blind
    prospective subjects to the risks or impair their
    ability to exercise proper judgment and
  • they may prompt subjects to lie or conceal
    information that, if known, would disqualify them
    from enrolling or continuing as participants
    in a research project.

20
Undue Influence versus Compensation
  • Some types of research involve a significant
    commitment from research participants in terms of
    time or effort, and investigators may wish to
    provide compensation.
  • Institutions should consider establishing
    standards for fair and appropriate compensation.
  • Compensation is meant to reimburse research
    participants for their time, research-related
    inconveniences and/or research-related
    discomforts
  • Compensation is not a benefit of the research.

21
Case Study Sleeping Sickness Study on Campus
  • An investigator, who is a professor at a large
    university, is developing a grant application for
    submission to the NIH to study sleeping sickness
    (trypanosomiasis)
  • The study will require fresh human blood daily
    for several months, and thus will require
    research participants.
  • It is now time to make a decision about
    recruitment of the research participants.

22
  • Based on the number of students and employees in
    her classes and lab, the researcher feels
    confident that she will have enough participants
    needed for the proposed research if she simply
    recruits among them. But she knows that some
    colleagues advertise their studies through
    postings on campus.
  • The investigator is faced with two possible
    options for recruiting normal, healthy research
    participants
  • Recruit the students in her upper level classes
    and the technicians from her lab, and give 5
    compensation to participants per blood draw, or
  • Recruit from the general university population
    (students, faculty and staff) by posting fliers
    around campus, and give 5 compensation to
    participants per blood draw

23
  • From which population would you advise the
    researcher to recruit?
  • Recruit the students in her upper level classes
    and the technicians from her lab to participate
    in the study
  • Post fliers around campus to recruit participants
    from the campus population (students, faculty and
    staff)

24
Correct answer is
  • Asking for study participants from a population
    over which a researcher has authority is not the
    best idea.
  • It is generally agreed that students and
    employees are groups that can be vulnerable to
    coercion.
  • Even though the researcher may feel confident
    that she would never let her students and
    employees decisions about participation affect
    her opinions about them, her students and
    employees might feel pressured to participate
    simply because she is in a position of authority.
  • Recruiting for the study participants from the
    students, faculty and staff of the university is
    the best choice.

25
Informed Consent
  • Definition A legally-effective, voluntary
    agreement that is given by a prospective research
    participant following comprehension and
    consideration of all relevant information
    pertinent to the decision to participate in a
    study
  • The HHS regulations require that investigators
    obtain legally effective informed consent from
    prospective participants in a way that allows
    them to consider whether or not to participate
    and that minimizes the possibility for coercion
    or undue influence .

26
Informed Consent (cont.)
  • The Belmont principle of respect for persons is
    primarily applied by requiring that all human
    subjects research participants provide voluntary
    informed consent to participate in research.
  • The three fundamental aspects of informed consent
    are
  • Voluntariness
  • Comprehension
  • Disclosure

27
Voluntariness
  • Individuals decisions about participation in
    research should not be influenced by anyone
    involved in conducting the research ...consent
    must be freely given or truly voluntary.

28
Comprehension
  • Individuals must have the mental or decisional
    capacity to understand the information presented
    to them in order to make an informed decision
    about participation in research.
  • Avoid Therapeutic Misconception

29
Disclosure
  • HHS regulations require that researchers
    disclose
  • The purpose of the study
  • Any reasonably foreseeable risks to the
    individual
  • Potential benefits to the individual or others
  • Alternatives to the research protocol
  • The extent of confidentiality protections for the
    individual
  • Compensation in case of injury due to the
    protocol
  • Contact information for questions regarding the
    study, participants rights, and in case of
    injury
  • The conditions of participation, including right
    to refuse or withdraw without penalty
  • This disclosure must be made in such a way that
    it provides a reasonable person the information
    she or he would need in order to make an informed
    decision.

30
Informed Consent (cont.)
  • Investigators are responsible for providing
    information during the informed consent process
    in a manner that is understandable to the
    potential participants.
  • Methods used in addition to a consent form to
    enhance individuals comprehension
  • Oral presentations (opportunity to
  • discuss the information and ask questions)
  • Providing additional educational materials,
  • such as brochures,
  • Video presentations
  • The informed consent process must be delivered in
    language that is understandable to the subject
    (reading levels of documents and translating
    documents into the language with which
    participants are most comfortable).

31
Requirements for Documentation of Informed
Consent
  • Informed consent must be documented using a
    written form that either contains all of the
    required elements or a short form that states
    that all of the required elements have been
    presented orally.
  • This form must be signed
  • by either the participant or
  • the participants legally
  • authorized representative

32
Case Study Sleeping Sickness Study on Campus
  • Now that your colleague studying sleeping
    sickness has decided on the method of recruitment
    for the study participants, she must write an
    informed consent document for the participants to
    sign.
  • The researcher has prepared two different draft
    consent documents and must select one to submit
    to her IRB for review.
  • Read the two consent documents and then choose
    the document that best informs the potential
    participants about the study in which they will
    enroll
  • Consent Document 1
  • Consent Document 2

33
Consent Document 1
  • Surface Antigen Expression in Trypanosomes
  • Dr. X
  • You are invited to participate in this
    study by giving blood on a voluntary basis, but
    no more than five times in an eight week period.
    The research project is anticipated to continue
    for four years.
  • All blood draws will be performed by
    qualified technicians at the Medical Center Blood
    Bank. 100 ml of blood will be withdrawn from a
    vein in your arm.
  • Although you will not benefit directly from
    participating in this study, you will make a
    major contribution to the information known about
    trypanosomiasis, also known as sleeping sickness.
    In the future, others may benefit because
    scientists and doctors will learn about how
    parasites cause sleeping sickness, and will
    develop vaccines to prevent it.
  • You will be paid 5 for the time and travel
    required to give blood.
  • Your signature on this form means that you
    understand that participation is voluntary, and
    you may withdraw from the study at any time.

34
Consent Document 2
  • Surface Antigen Expression in Trypanosomes
  • Dr. X
  • Dr. Xs
  • laboratory studies the parasite which causes
    trypanosomiasis, also known as sleeping sickness.
    This study will look at the effects of different
    surface antigens (proteins) produced by the
    parasites in human blood. The goal is to identify
    how different surface antigens are expressed by
    the parasites.
  • You are invited to participate in this study by
    giving blood on a voluntary basis, but no more
    than five times in an eight week period. The
    research project is anticipated to continue for
    four years.
  • All blood draws will be performed by qualified
    technicians at the Medical Center Blood Bank. 100
    ml of blood will be withdrawn from a vein in your
    arm. None of the procedures are experimental.
  • During the collection of blood, you may
    experience discomfort and bruising at the site of
    collection. To minimize these risks, you will be
    asked to lie down while an experienced technician
    collects the blood sample. You may feel light
    headed after having blood drawn. If you feel
    faint, you should not get up and should notify a
    nurse.
  • Although you will not benefit directly from
    participating in this study, you will make a
    major contribution to the information known about
    sleeping sickness. In the future, others may
    benefit because scientists and doctors will learn
    about how parasites cause sleeping sickness and
    will develop vaccines to prevent it.
  • A research assistant will keep a record of all
    blood draws in a secure database. Only the
    professional staff at the Medical Center will
    know the identity of study participants.
  • You will be paid 5 for the time and travel
    required to give blood. If you feel that you have
    been injured as a direct result of participating
    in the study, please contact Dr. X at
    123-456-7890.
  • Your signature on this form means that you
    understand the information presented, and that
    you want to participate in the study. You
    understand that participation is voluntary, and
    you may withdraw from the study at any time.

35
  • Which of these two consent documents would you
    choose to use?
  • Choose Consent Document 1
  • Choose Consent Document 2

36
Consent Document 2 is the best choice
  • Consent Document 2 contains all of the required
    elements of informed consent and protects against
    the perception of coercion by emphasizing the
    fact that participation is voluntary and
    explaining how someone can withdraw from the
    study if they wish.
  • Consent Document 2 includes the following
    required elements of informed consent
  • The purpose of the study
  • Foreseeable risks/discomforts to the individual
  • Potential benefits to the individual or others
  • Confidentiality protections for the individual
  • Compensation plan
  • Contact information for questions regarding the
    study, participants rights, and in case of
    injury
  • The conditions of participation, including right
    to refuse or withdraw without penalty

37
Diminished Autonomy
  • An individuals autonomy can be affected by
    several factors including age, cognitive
    impairment, illness, and treatments.
  • An individuals capacity to consent to a
    particular study should be assessed based on
  • The individuals level of capacity, and
  • The complexity and risks of the study, i.e., the
    capacity needed for an individual to be able to
    understand the study well enough to consent to
    participate

38
Decisional Capacity and Legally Authorized
Representatives
  • It is required that legally authorized
    representatives provide voluntary informed
    consent for individuals with diminished capacity
    to participate in research

39
The HHS Regulations
  • Subpart A Basic HHS Policy for Protection of
    Human Research Subjects
  • Subpart B Additional Protections for Pregnant
    Women, Human Fetuses and Neonates Involved in
    Research
  • Subpart C Additional Protections Pertaining to
    Biomedical and Behavioral Research Involving
    Prisoners as Subjects
  • Subpart D Additional Protections for Children
    Involved as Subjects in Research
  • Other vulnerable populations include mentally
    disabled persons and economically and/or
    educationally disadvantaged persons.

40
Participation of Pregnant Women in Research
  • The HHS regulations prohibit
  • Inducements of any kind to terminate a pregnancy
  • Investigators from taking part in decisions about
    terminating a pregnancy
  • Investigators from determining the viability of a
    neonate

41
Childrens Participation in Research
  • Children may not have full capacity to make
    decisions in their own best interests and
    therefore
  • Children are considered a vulnerable population,
    and
  • Children are unable to provide legally effective
    informed consent
  • Because children cannot provide informed consent,
    children provide assent to participate in
    research, to the extent that they are able, and
    parents/guardians give permission for a child to
    participate in research.
  • Assent affirmative agreement to
    participate in research. Mere failure to object
    should not, absent affirmative agreement, be
    construed as assent.

42
Excluding Children from Research
  • The NIH Policy and Guidelines on the Inclusion of
    Children in Research states that children must be
    included in all NIH-supported human subjects
    research unless there are scientific and
    ethical reasons not to include them.

43
Obtaining Informed Consent from Prisoners
  • Requirements specific to informed consent for
    prisoners are
  • Not to be under constraints as a result of their
    incarceration that could affect their ability to
    make a truly voluntary decision about whether or
    not to participate in research.
  • Adequate assurance exists that parole boards will
    not take into account a prisoners participation
    in the research in making decisions regarding
    parole, and each prisoner is clearly informed in
    advance that participation in the research will
    have no effect on his or her parole

44
Case Study Fetal ImagingWHAT DO YOU THINK?
  • Indicate whether the HHS regulations require the
    investigator to provide additional protections
    for participants in the study under Subparts B, C
    or D
  • A study proposes to test a novel fetal imaging
    technology designed to enhance image quality and
    allow physicians to assess more accurately
    prenatal health. This technology has been tested
    both on pregnant mammals and non-pregnant women
    with no adverse effects. Women will be recruited
    at their regularly scheduled prenatal check-ups
    and those who consent to participate will receive
    the experimental scan
  • Does this study require the investigator to
    provide additional protections for participants?
  • Yes, the study involves a vulnerable population
  • No, the study does not involve a vulnerable
    population

45
Yes, the study involves a vulnerable population
  • Correct!
  • This study involves a vulnerable population.
    Because the research will be conducted with
    pregnant women and fetuses, the requirements of
    Subpart B apply.

46
Case Study Treatment and Prevention Research in
Adolescents
  • Indicate whether the HHS regulations require the
    following studies to provide additional
    protections for the studys subject populations
    under Subparts B, C or D
  • A study proposes to examine the effectiveness of
    a medical treatment and prevention program for
    adolescents in a location where the legal age for
    consent to such treatment is 12. The adolescents
    involved range from ages 12 to 17.

Does this study require additional protections
be provided for the subject population?
                           
47
Case Study Lack of Assent from a Child
  • A 7-year-old child has a rare genetic disorder.
    No treatment is currently available. You have
    designed a longitudinal study that will examine
    the progression of the disorder. The study will
    involve standard physical and psychological
    examinations, including drawing 10ml of blood 4
    times per year.
  • After enrollment, at which time the parents
    provided permission for the child to participate
    in the study and the child provided assent, he
    panics and screams that he doesnt want to
    participate and wants to go home when he sees the
    nurse holding a needle for the blood draw. The
    parents are present and want the child to
    participate.
  • Do you need to withdraw this child from your
    study because he has withdrawn his assent?

48
  • This is not an easy question because it does not
    have a clear yes or no answer. Various issues
    to consider are explored
  • Is the child old enough to provide assent?
  • Does the study offer the prospect of direct
    benefit to the children enrolled?
  • How severe is the childs fear, and how insistent
    is he not to participate?
  • Is there a way that could elevate the childs
    fear so he can participate?

49
No, the study does not involve a vulnerable
population
  • The correct answer is No.
  • Because the location in which the research will
    be conducted allows 12-year-olds to consent to
    the treatment, the participants in this research
    are not considered children under the HHS
    regulations and can provide informed consent to
    participate in the study. While the regulations
    do not require the additional protections of
    Subpart D for children in this study, the IRB may
    require some additional protections if they feel
    that the adolescents who will be involved in the
    study are vulnerable.

50
Case Study 3 Observational Study of Challenges
Returning to Work WHAT DO YOU THINK?
  • Indicate whether the HHS regulations require the
    following studies to provide additional
    protections for the studys subject populations
    under Subparts B, C or D
  • A study proposes to observe the challenges for
    former prisoners returning to office jobs.
    Researchers will recruit individuals who have
    spent over ten years in prison, have completed
    their sentences, and are now interviewing for
    office jobs.
  • Does this study requires additional protection
    for the subject population?
  • Yes, the study involves a vulnerable population
  • No, the study does not involve a vulnerable
    population

51
No, the study does not involve a vulnerable
population
  • Correct!
  • This study does not involve a vulnerable
    population. The participants in this research are
    not considered prisoners, per Subpart C, because
    they have completed their period of involuntary
    confinement and are no longer confined or
    detained in a penal institution nor are they
    detained pending arraignment, trial, or
    sentencing.

52
  • In some cultures it is not appropriate to obtain
    informed consent solely from the individual
    participants, because the individuals interests
    may be considered to be intimately entwined with
    their communitys interests.
  • It is often achieved through meetings with large
    groups of community representatives or community
    leaders.
  • It is appropriate to consult a community before
    conducting research when the research involves
    risk to discrete, identifiable populations. For
    example, members of a community may feel
    stigmatized if a number of members of that
    community participate in research that may reveal
    unpopular or dangerous traits.

53
2. Beneficence
54
2. Beneficence
  • Two general rules have been articulated as
    complementary expressions of beneficent actions
  • Do no harm
  • Maximize possible benefits and minimize possible
    harms
  • The challenge inherent in applying the
    Belmont principle of beneficence is how to
    determine when potential benefits outweigh
    considerations of risks and vice versa.

55
Minimal harm
  • Minimal harm is defined as
  • that the probability and magnitude of harm or
    discomfort anticipated in the research are not
    greater than those ordinarily encountered in
    daily life or during the performance of routine
    physical or psychological examinations or tests.

56
Risk of Research
  • A. Physical
  • Physical risks may include pain, injury, and
    impairment of a sense such as touch or sight.
    These risks may be brief or extended, temporary
    or permanent, occur during participation in the
    research or arise after.
  • Physical risks in research can be minimized by
    carefully following protocols, by having trained
    individuals conduct research procedures, through
    careful monitoring of research participants
    health status, by recruiting appropriate
    populations, and by providing clinical care when
    needed.

57
Risk of Research (cont.)
  • B. Psychological
  • Psychological risks can include anxiety, sadness,
    regret and emotional distress, among others.
    Specially in behavioral studies.
  • Possible ways to protect against psychological
    risks include reminding participants of their
    right to withdraw from research or limit their
    participation if they become uncomfortable, and
    providing counseling or psychological support for
    participants who experience distress

58
Risk of Research (cont.)
  • C. Psychological
  • Social risks can range from jeopardizing the
    individuals reputation and social standing, to
    placing the individual at-risk of political or
    social reprisals.
  • Minimizing social risks to participants involves
    protecting confidential data, including not only
    the data collected, but the fact of participation
    in the research project itself.

59
Risk of Research (cont.)
  • D. Legal
  • Legal risks include the exposure of activities of
    a research subject that could reasonably place
    the subjects at risk of criminal or civil
    liability
  • Protections against legal risks often involve
    protecting the confidentiality of research data.
    For studies conducted in the United States,
    investigators can apply for Certificates of
    Confidentiality, which are intended to prevent
    investigators from being forced to disclose data
    that can be linked to identifiable research
    participants in legal proceedings.

60
Risk of Research (cont.)
  • E. Economic
  • Economic risks may exist if knowledge of ones
    participation in research, for example, could
    make it difficult for a research participant to
    retain a job or to find a job, or if insurance
    premiums increase or loss of insurance is a
    result of the disclosure of research data.
  • Protecting confidentiality of data is one method
    for protecting against economic risks, such as
    those to employability and insurability.
    Investigators may elect to keep research data
    separate from medical records in order to prevent
    employers and insurance companies from obtaining
    information that could put the participants at
    risk.

61
Privacy and Confidentiality
  • Investigators are responsible for
  • Protecting privacy of individuals
  • Confidentiality of data
  • Privacy means being free from unsanctioned
    intrusion
  • Confidentiality means holding secret all
    information relating to an individual, unless the
    individual gives consent permitting disclosure

62
Coded Private Information and Human Subjects
Research
  • Research with coded private information or
    specimens does not involve human subjects if
  • The private information or specimens were not
    collected specifically for the currently proposed
    research project through an interaction or
    intervention with living individuals and
  • The investigator(s) cannot readily ascertain the
    identity of the individual(s) to whom the coded
    private information or specimens pertain

63
Case Study Confidentiality in Clinical Research
  • After the conclusion of a clinical trial in a
    small rural community, an investigator is anxious
    to publish findings. Understanding the NIH
    policies encouraging the reporting of demographic
    differences in intervention effect, and concerned
    about protecting the confidentiality of research
    participants, the investigator publishes only
    general demographic data such as sex, age, state,
    and county.
  • Is this an appropriate and acceptable way to
    protect the confidentiality of research
    participants?
  • Yes, this is an appropriate and acceptable way to
    protect the confidentiality of research
    participants.
  • No, this is NOT an appropriate and acceptable way
    to protect the confidentiality of research
    participants.

64
Case Study Research with Anonymized Data
  • You are an investigator proposing to use data
    from a colleagues database to conduct secondary
    analyses. Your colleague will provide coded data
    for your proposed studies, and you and he enter
    into an agreement by which he will keep the key
    to the code and will have no other involvement in
    the research.
  • Does this study involve human subjects?
  • Yes, this study involves human subjects.
  • No, this study does not involve human subjects.

65
Case Study Esophageal Cancer
  • A group of investigators proposes to investigate
    genetic factors that may increase risks for
    esophageal cancer. Genetic factors in esophageal
    cancer are not well understood and esophageal
    cancer occurs in many racial and ethnic
    populations. The investigators propose to collect
    DNA from cheek swabs and administer a risk factor
    questionnaire. Both cancer patients and
    age-matched controls will be included.
  • The investigators have access to a predominantly
    Caucasian sample, and have no plans to recruit
    participants outside of their available pool.
  • Is this an acceptable strategy?
  • Yes, this is an acceptable strategy
  • No, this is not an acceptable strategy

66
Anticipated Benefits Greater than Potential Harms
  • Research requires that
  • Risks are minimized
  • Unavoidable risks are justified as necessary for
    sound scientific design
  • Research studies are anticipated to make progress
    toward important, generalizable knowledge

67
Debriefing
  • To Debrief or Not to Debrief
  • Debriefing of research participants after the
    study involves an explanation of the incomplete
    disclosure of research steps to participants
  • Debriefing is generally considered to be
    appropriate, but must depend on whether the
    disclosure will result in harm.

68
Institutional Review Boards (IRB)
  • IRBs determine
  • the acceptability of proposed research in terms
    of institutional commitments and regulations,
    applicable law, and standards of professional
    conduct and practice

69
IRB Role
  • The major roles of IRBs in the oversight of
    research are
  • Initial review and approval or disapproval of the
    proposed research activity
  • Ensuring that the proposed informed consent
    process meets all of the requirements
  • Providing continuing oversight for progress
    reports and protocols for ongoing research
    studies Data and safety monitoring

3. Justice
71
3. Justice
  • Justice requires that individuals and groups be
    treated fairly and equitably in terms of bearing
    the burdens and receiving the benefits of
    research.
  • The principle of justice may arise in decisions
    about inclusion and exclusion criteria for
    participation in research and requires
    investigators to question whether groups are
    considered for inclusion simply because of their
    availability, their compromised position, or
    their vulnerability rather than for reasons
    directly related to the problem being studied.

72
Types of Justice
73
Individual Justice and Social Justice
  • Individual justice requires that investigators
    should not offer potentially beneficial research
    only to some patients who are in their favor or
    select only undesirable persons for risky
    research.
  • Social justice requires that distinction be
    drawn between classes of subjects that ought, and
    ought not, to participate in any particular kind
    of research, based on the ability of members of
    that class to bear burdens and on the
    appropriateness of placing further burdens on
    already burdened persons.

74
Equity vs. Equality in Human Subjects Research
  • The meanings of equity and equality are
    similar, but not the same.
  • To treat equitably means to treat fairly
  • To treat equally means to treat in exactly the
    same way.

75
Equitable Distribution
  • In order to achieve an equitable distribution of
    the risks and potential benefits of the research,
    investigators must determine the distribution of
    different groups (men and women, racial or ethnic
    groups, adults and children, age, etc.) in the
    populations that
  • May be affected by the disease or condition under
    study, and
  • That are anticipated to benefit from the
    knowledge gained through the research

Case Study Migraine Intervention Trial
  • A researcher seeks to improve treatment for
    severe migraines that are partially responsive to
    oral medication. He proposes to test whether
    acupuncture, in addition to a sufferers oral
    medication, is more effective treatment than oral
    medication alone. Because women are three times
    more likely to experience migraines than men, he
    proposes to enroll three times as many women as
    men. They will be recruited from racially and
    ethnically diverse communities.
  • Does this study design fulfill the principle of
    justice?
  • Yes, this study design does fulfill the principle
    of justice
  • No, this study design does not fulfill the
    principle of justice

78
Yes, this study design does fulfill the principle
of justice
  • Correct!
  • The research includes women and men in proportion
    to the rates of severe migraines experienced by
    each sex, and is designed to have racial and
    ethnic diversity.
  • The study provides both sexes and racial/ethnic
    communities with the opportunity for benefits
    from the clinical trials, and does not unfairly
    burden any single group with the risks of
    research. Its design is fair.

79
Justice and the Use of Placebos
  • A researchers duty is not to exploit or
  • deceive research participants and to treat
    them fairly.
  • The informed consent process must disclose
    sufficient information to ensure that potential
    research participants
  • Understand what placebos are
  • Understand the likelihood that they will receive
    a placebo
  • Are able to provide their fully informed consent
    that they are willing to receive a placebo
  • Misleading research participants about the
    research purpose or procedures

80
Review
Investigators should allow Individuals to make
their own decisions
Justice
Investigators should design research studies as
to maximize benefit and minimize risk to
individuals
Respect
Individuals who are less able to take decisions
for themselves require additional protection
Beneficence
The burdens and benefits of research should be
fairly distributed among individuals and society
81
Fairness in International Research
  • A few of the many issues that demand careful
    consideration with respect to justice, as well as
    beneficence and respect for persons, include
  • How can research conducted in resource-poor
    setting avoid exploiting participants?
  • What is owed to participants in clinical research
    and to the population of the host country after
    studies are complete?
  • In addition to following the HHS regulations,
    what standards and assurances to protect research
    participants should investigators and non-US
    institutions use when conducting research abroad?
  • How can regional or cultural differences be
    negotiated?
  • For settings where cultural values impact
    informed consent, how should processes be
    altered?

82
Sustaining Benefits Locally
  • Investigators should
  • Think about how benefits to individual research
    participants and the local population may be
    sustained after the study is complete
  • Consider how any effective treatment emerging
    from the research could be provided to the rest
    of the population

83
Standards and Assurances for International
Research
  • The HHS Office for Human Research Protections
    (OHRP) has set the expectation that the HHS
    regulations, as well as any additional
    institutional and local standards, will be
    followed in all research conducted or supported
    by HHS.

84
IRB Review for Research in International
Settings
  • Knowledge of the local context may be provided
    by
  • Specialists with personal, direct knowledge of
    the local research context who participate in IRB
    discussions and provide insight on achieving
    protections for research participants
  • An IRB representative situated within the local
    research context

85
Research Ethical Committee (REC) in HMC
  • Hamad Medical Corporation in Qatar, parallels a
    similar approved protocols of IRB
  • Research Ethical Committee (REC) in HMC is based
    upon IRB regulations and terms
