- 45 CFR 46: Title 45, Part 46 of the Code of Federal Regulations, Protection of Human Subjects. Most recently updated in June 1991 (Subpart B in 2002),
these regulations govern human subject research conducted by all federal agencies.
Together, this body of regulations governs the conduct of human subject research today.
- 510(K) Device: A medical device that is considered substantially equivalent to a device that was
or is being legally marketed. A sponsor planning to market such a device must submit
notification to the FDA 90 days in advance of placing the device on the market. If
the FDA concurs with the sponsor, the device may then be marketed. 510(k) is the section
of the Food, Drug and Cosmetic Act that describes premarket notification; hence the
designation "510(k) device."
- Adjuvant Therapy: Therapy provided to enhance the effect of a primary therapy; auxiliary therapy.
- Adverse Effect: An undesirable and unintended, although not necessarily unexpected, result of therapy
or other intervention (e.g., headache following spinal tap or intestinal bleeding
associated with aspirin therapy).
- Adverse Event (AE): Any experience or abnormal finding that has taken place during the course of a research
project and was harmful to the subject participating in the research, or increased
the risks of harm from the research, or had an unfavorable impact on the risk/benefit
ratio; Any untoward or unfavorable medical occurrence in a clinical research study
participant, including any abnormal sign (e.g. abnormal physical exam or laboratory
finding), symptom, or disease, temporally associated with the participants’ involvement
in the research, whether or not considered related to participation in the research.
- Arm: A group or subgroup of participants in a clinical trial that receives specific interventions,
or no intervention, according to the study protocol. This is decided before the trial
- Assent [DOC]: An agreement by an individual not competent to give legally-valid informed consent
(e.g., a child aged 7+ or cognitively-impaired person) to participate in research
- Assent of a Child: Assent means a child's affirmative agreement (verbal or written) to participate in
a clinical investigation. Mere failure to object may not, absent affirmative agreement,
be construed as assent.
- Baseline: The initial time point in a clinical trial that provides a basis for assessing changes
in subsequent assessments or observations. At this reference point, measurable values
such as physical exam, laboratory tests, and outcome assessments are recorded.
- Belmont Report: A statement of basic ethical principles governing research involving human subjects
issued by the National Commission for the Protection of Human Subjects in 1978
- Beneficence: An ethical principle discussed in the Belmont Report that entails an obligation to
protect persons from harm. The principle of beneficence can be expressed in two general
rules: (1) do not harm; and (2) protect from harm by maximizing possible benefits
and minimizing possible risks of harm.
- Bias: A point of view or preference which prevents impartial judgment in the way in which
a measurement, assessment, procedure, or analysis is carried out or reported.
- Biologic: Any therapeutic serum, toxin, anti-toxin, or analogous microbial product applicable
to the prevention, treatment, or cure of diseases or injuries.
- Case-Control Study: A study comparing persons with a given condition or disease (the cases) and persons
without the condition or disease (the controls) with respect to antecedent factors.
- Case Report Form (CRF): A printed, optical, or electronic (eCRF) document designed to capture all protocol-required
information for a study.
- Case Report or Case Study: A case report is one in which three or fewer records are accessed. Case reports do
not meet the definition for human subjects research and do not require submissions
to the IRB if the project meets the following criteria:
A worksheet is available on our website that can help an investigator determine if their project qualifies as a case report.
- Nothing was done to the patient(s) with prior research intent.
- The case report does not contain elements of a systematic investigation (e.g. statistical
- The case report describes an interesting treatment, presentation or outcome.
- The published article will not contain any identifiable information or authorization
has been obtained.
- CAT Scan: Abbreviation for Computerized Axial Tomography, an X-ray technique for producing images of internal bodily structures through the
assistance of a computer.
- CDC: Centers for Disease Control and Prevention; an agency within the Public Health Service,
Department of Health and Human Services.
- Cell Lines: A cell-line refers to a collection of a participant's white blood cells that are kept
alive, usually stored in a freezer. Researchers are able to study these cells repeatedly
for many years.
- Central Institutional Review Board (CIRB): The Central IRB (CIRB) Initiative is designed to help reduce the administrative burden
on local IRBs and investigators while continuing a high level of protection for human
research participants. A local IRB's use of the CIRB facilitated review mechanism
is intended to enable an investigator to enroll patients into adult and pediatric
Cooperative Group clinical trials significantly faster than when employing traditional
method of IRB review. The CIRB Initiative is sponsored by NCI in consultation with
the Department of Health and Human Services Office for Human Research Protections
- Cell Lines: A cell-line refers to a collection of a participant's white blood cells that are
kept alive, usually stored in a freezer. Researchers are able to study these cells
repeatedly for many years.
- Center for Clinical and Translational Science (CCTS): The goal of CCTS is to integrate existing biostatistical resources, including specialized
biostatistical expertise at University Departments, into a core that provides researchers
with access to both general study support and expertise specialized to specific research
areas. CCTS currently supports a wide range of adult and pediatric research studies
that address important problems in neurology, musculoskeletal disease, obesity, diabetes,
infectious disease, dermatology, cancer, inheritable conditions and others. Their
services are not limit to a particular patient population or categorical research
- Certificate of Confidentiality: A document that provides additional protection of data from legal subpoena. The Certificate
provides protection against compelled disclosure of identifying information or other
identifying characteristics of a research participant enrolled in biomedical, behavioral,
clinical, and other forms of sensitive research.
- Children: Persons who have not attained the legal age for consent to treatment or procedures
involved in the research, as determined under the applicable law of the jurisdiction
in which the research will be conducted.
- Class I, II, III Devices: Classification by the Food and Drug Administration of medical devices according to
potential risks or hazards.
- Clinical Investigation (FDA Definition): Any experiment that involves a test article and one or more human subjects and is
subject to requirements for submission to the Food and Drug Administration. Clinical investigations must not be initiated unless that investigation has been reviewed and approved by
- Clinical Research (NIH Definition): The NIH defines clinical research as:
- Patient-oriented research. Research conducted with human subjects (or on material
of human origin such as tissues, specimens and cognitive phenomena) for which an investigator
directly interacts with human subjects. Excluded from this definition are in vitro
studies that utilize human tissues that cannot be linked to a living individual. Patient-oriented
research includes: (a) mechanisms of human disease, (b) therapeutic interventions,
(c) clinical trials, or (d) development of new technologies.
- Epidemiologic and behavioral studies.
- Outcomes research and health.
- Clinical Research or Study Coordinator (CRC): An individual that handles the administrative and day-to-day responsibilities of
a clinical trial and acts as a liaison for the clinical site. This person may collect
the data or review it before it is entered into a study database.
- Clinical Trial: The definition of a clinical trial according to the revised Common rule and NIH is
a research study in which one or more human subjects are prospectively assigned to
one or more interventions (which may include placebo or other control) to evaluate
the effects of the interventions on biomedical or behavioral health-related outcomes.
The FDA definition of a clinical investigation does not encompass some studies, such
as behavioral interventions and surgical procedures. The FDA regulates safety/efficacy
for only some kinds of therapies and diagnostics that are related to pharmaceuticals,
devices and biologics. Therefore, there are some studies that will not meet the definition
of a clinical investigation according to the FDA but are still considered a clinical
trial according to the revised Common Rule and the NIH.
- Phase 1 Trial: Includes the initial introduction of an investigational new drug into humans. These
studies are typically conducted with healthy volunteers, typically in a very small
number of individuals (e.g. 20-80 people). Phase 1 trials are designed to determine
the metabolic and pharmacological actions of the drug in humans, the side effects
associated with increasing doses (to establish a safe dose range), and, if possible,
to gain early evidence of effectiveness. The ultimate goal of Phase 1 trials is to
obtain sufficient information about the drug's pharmacokinetics and pharmacological
effects to permit the design of well-controlled, sufficiently valid Phase 2 studies.
Other examples of Phase 1 studies include studies of drug metabolism, structure-activity
relationships, and mechanisms of actions in humans, as well as studies in which investigational
drugs are used as research tools to explore biological phenomena or disease processes.
- Phase 2 Trial: Includes controlled clinical studies conducted to evaluate the drug's effectiveness
for a particular indication in patients with the disease or condition under study,
and to determine the common short-term side effects and risks associated with the
drug. These studies are typically well controlled, closely monitored, and conducted
with a relatively small number of patients, usually involving no more than several
- Phase 3 Trial: Involves the administration of a new drug to a larger number of patients (e.g. several
hundred - several thousand) in different clinical settings to determine its safety,
efficacy, and appropriate dosage. They are performed after preliminary evidence of
effectiveness has been obtained, and are intended to gather necessary additional information
about effectiveness and safety for evaluating the overall benefit-risk relationship
of the drug, and to provide and adequate basis for physician labeling. An NIH-defined
Phase III clinical trial is a broadly based prospective Phase III clinical investigation,
usually involving several hundred or more human subjects, for the purpose of evaluating
an experimental intervention in comparison with a standard or controlled intervention
or comparing two or more existing treatments. Often the aim of such investigation
is to provide evidence leading to a scientific basis for consideration of a change
in health policy or standard of care. The definition includes pharmacologic, non-pharmacologic,
and behavioral interventions given for disease prevention, prophylaxis, diagnosis,
or therapy. Community trials and other population-based intervention trials are also
included. In Phase 3 studies, the drug is used the way it would be administered when
marketed. When these studies are completed and the sponsor believes that the drug
is safe and effective under specific conditions, the sponsor applies to the FDA for
approval to market the drug.
- Phase 4 Trial: Studies conducted after a drug has been approved by FDA, to delineate additional information
about the drug's risks, benefits, and optimal use. These studies could include, but
would not be limited to, studying different doses or schedules of administration than
were used in Phase 2 studies, use of the drug in other patient populations or other
stages of the disease, or use of the drug over a longer period of time. These studies
are designed to monitor effectiveness of the approved intervention in the general
population and to collect information about any adverse effects associated with widespread
- Code of Federal Regulations (CFR): The Code of Federal Regulations is an annual codification of the general and permanent
rules published in the Federal Register by the executive departments and agencies
of the Federal Government. The CFR is divided into 50 titles representing broad areas
subject to Federal regulation. Each Title is divided into chapters that are assigned
to agencies issuing regulations pertaining to that broad subject area. Each chapter
is divided into parts and each part is then divided into sections -- the basic unit
of the CFR. The purpose of the CFR is to present the official and complete text of
agency regulations in one organized publication and to provide a comprehensive and
convenient reference for all those who may need to know the text of general and permanent
Federal regulations (National Archives).
- Cognitively Impaired: Having either a psychiatric disorder (e.g., psychosis, neurosis, personality or behavior
disorders, or dementia) or a developmental disorder (e.g., mental retardation) that
affects cognitive or emotional functions to the extent that capacity for judgment
and reasoning is significantly diminished. Others, including persons under the influence
of or dependent on drugs or alcohol, those suffering from degenerative diseases affecting
the brain, terminally ill patients, and persons with severely disabling physical handicaps,
may also be compromised in their ability to make decisions in their best interests.
- Cohort: A group of subjects initially identified as having one or more characteristics in
common who are followed over time. In social science research, this term may refer
to any group of persons who are born at about the same time and share common historical
or cultural experiences.
- Collaborative IRB Training Initiative (CITI): An internet-based set of educational modules on the protection of human participants
in research. It is sponsored by a consortium of IRB professionals and researchers
from universities and medical schools across the country and is administered by the
University of Miami (see: www.citiprogram.org).
- Common Rule: The Common Rule, which governs research with human subjects conducted or supported
by 15 federal departments and agencies including EPA, establishes a comprehensive
framework for the review and conduct of proposed human research to ensure that it
will be performed ethically. EPA's codification of the Common Rule. The central requirements of the Common Rule are:
- That people who participate as subjects in covered research are selected equitably
and give their fully informed, fully voluntary written consent; and
- That proposed research be reviewed by an independent oversight group referred to as
an Institutional Review Board (IRB), and approved only if risks to subjects have been
minimized and are reasonable in relation to anticipated benefits, if any, to the subjects,
and the importance of the knowledge that may reasonably be expected to result.
- Compassionate Use of Investigational Devices: The FDA defines "compassionate use" as the use of a test article on a human subject
with a serious disease or condition for which there is no acceptable treatment available.
FDA and IRB approval for compassionate use is required. The IRB will not approve an
application for compassionate use until it has been approved by the FDA.
- Company Protocol: A document used to define and manage the trial usually sent by the Industry Sponsor
or the lead site if it is a multi-center study. Not all studies will include a protocol,
but studies that involve investigational drugs; investigational devices will always
have this document. The protocol describes the scientific rationale, objective(s),
design, methodology, statistical considerations and organization of the planned trial.
The protocol contains a precise study plan to assure safety and health of the trail
subjects and to provide an exact template for trial conduct by investigators. This
allows data to be combined across all investigators/sites. The format and content
of clinical trial protocols sponsored by pharmaceutical, biotechnology, or medical
device companies in the United States, European Union, or Japan have been standardized
to follow Good Clinical Practice guidance.
- Concomitant Medication: Prescription and over-the-counter drugs and supplements a study participant has taken
along with the study intervention. This information may be collected as a history
item as well as during the study. Some studies may collect only those medications
that may interact with the study or intervention or that may exclude an individual
from participating in a study.
- Conflict of Interest: The real or apparent interference of one person's interests with the interests of
another person, where potential bias may occur due to prior or existing personal or
professional relationships. A conflict of interest occurs when individuals involved
with the conduct, reporting, oversight, or review of research also have financial
or other interests, from which they can benefit, depending on the results of the research.
- Consent Document(s): Commonly referred to as the "ICF" or "Informed Consent Form." These are the documents
presented to a subject or parent guardian prior to beginning a study. Most studies
will have this document submitted with the proposal, unless requesting a Waiver (see
below). The IRB has provided a template on the web site for investigators to prepare
- Adult Informed Consent: This is required when subjects are 18 years and older. This should be written to the
subject using appropriate language ("you").
- Parental Permission Document:This is required when subjects are 17 years and younger. This should be written to
the parent/guardian using appropriate language ("your child").
- Assent Document: Assent is an agreement by an individual not competent to give legally valid informed
consent (e.g., a child aged 7+ or cognitively-impaired person) to participate in research.
This is required for children enrolled in studies that are 7-17 years of age. If the
board deems appropriate, this can be requested for younger children.
- Contraindicated: Disadvantageous, perhaps dangerous; a treatment that should not be used in certain
individuals or conditions due to risks (e.g., a drug may be contraindicated for pregnant
women and persons with high blood pressure).
- Control Group: The group of individuals in a clinical trial assigned to a comparison intervention.
- Controlled Trial: A type of clinical trial in which observations made during the trial are compared
to a standard (called the control). The control may be observations from a group of
participants in the same trial or observations from outside the trial (for example,
from an earlier trial, called a historical control).
- Controls, Historical: Control subjects (followed at some time in the past or for whom data are available
through records) who are used for comparison with subjects being treated concurrently.
The study is considered historically controlled when the present condition of subjects
is compared with their own condition on a prior regimen or treatment.
- Coordinating Center: A group organized to coordinate the planning and operational aspects of a multi-center
clinical trial. CCs may also be referred to as Data Coordinating Centers (DCCs) or
Data Management Centers (DMCs).
- Covered Entity: Health care providers who conduct certain financial and administrative transactions
electronically, such as billing and fund transfers; also, all health plans and health
care clearinghouses (45 CFR 160.103). Covered Entities must comply with HIPAA regulations.
The University of Utah's Covered Entity includes nearly all parts of the University
of Utah Health Sciences Center. Contact the HIPAA Regulatory Office (587 9241) or
go to Covered Entity for information on the University offices that are inside or outside the Covered
Entity. Primary Children's Hospital, Veteran's Affairs Salt Lake City Health Care
System, and Shriners Hospitals for Children Intermountain are separate covered entities.
- Crossover Design: Describes a clinical trial in which groups of participants receive two or more interventions
in a particular order. For example, a two-by-two crossover design involves two groups
of participants. One group receives drug A during the initial phase of the trial,
followed by drug B during a later phase. The other group receives drug B during the
initial phase, followed by drug A during a later phase. So during the study, participants
"cross over" to the other drug. All participants receive drug A and drug B at some
point during the study, but in a different order, depending on the group to which
they are assigned.
- CTSI:Clinical & Translational Science Institute (formerly known as the CCTS, GCRC): The goal of CTSI is to integrate existing biostatistical
resources, including specialized biostatistical expertise at University Departments,
into a core that provides researchers with access to both general study support and
expertise specialized to specific research areas. CTSI currently supports a wide range
of adult and pediatric research studies that address important problems in neurology,
musculoskeletal disease, obesity, diabetes, infectious disease, dermatology, cancer,
inheritable conditions and others. Their services are not limit to a particular patient
population or categorical research area. Investigators from all research disciplines
are encouraged to take full advantage of the resources the unit offers.
- Cytogenetic Testing: Cytogenetics is the study of the structure of chromosome material. When cytogenetic
testing is used, typically study doctors want to know about changes in the chromosomes
seen by microscope with either G-banding (conventional staining of the chromosomes)
and/or fluorescent in situ hybridization (FISH). This assists study doctors in identifying
chromosomal abnormalities that might affect the development of a particular condition
and its treatment. In some forms of cancer, especially hematological malignancies,
cytogenetics can determine which chromosomal translocations are present in the malignant
cells, facilitating diagnosis and susceptibility to treatment.
- Data and Safety Monitoring Board (DSMB)[PDF]: A committee of scientists, physicians, statisticians, and others that collects and
analyzes data during the course of a clinical trial to monitor for adverse effects
and other trends (such as an indication that one treatment is significantly better
than another, particularly when one arm of the trial involves a placebo control) that
would warrant modification or termination of the trial or notification of subjects
about new information that might affect their willingness to continue in the trial.
- Data Management: The processes of handling the data collected during a clinical trial from development
of the study forms/CRFs through the database locking process and transmission to statistician
for final analysis.
- Data Management Plan (DMP): A plan that documents the processes for handling the flow of data from collection
through analysis. Software and hardware systems along with quality control and validation
of these systems, as relevant are described.
- Data Safety Monitoring Plan: Data and Safety Monitoring means the process to ensure and maintain the scientific
integrity of human subject research and to protect the safety of human subjects, a
system for appropriate oversight and monitoring to ensure the safety of participants
and the validity of the data. The section of a protocol that describes the steps to
identify physical, social, or psychological occurrences that may result from participation
in the research study and explains in detail how such occurrences will be handled
and reported. A DSMP describes the timing, tools and/or method(s) for monitoring and
evaluation, procedures for treatment or resolution (including circumstances which
would result in halting or terminating research), procedures for and timing of reports
to oversight bodies, and description of oversight bodies involved with the study (e.g.
FDA, IRB, or Data and Safety Monitoring Board). A study does not need to have a Data
and Safety Monitoring Board to have a DSMP.
- Data Transfer Agreement/Data Use Agreement: A Data Use Agreement (DUA) is a contractual document used for the transfer of data
that has been developed , where the data is nonpublic or is otherwise subject to some
restrictions on its use. Often this data is a necessary component of a research project
and it may or may not be human subject data from a clinical trial, or limited data
set information as defined in HIPAA. Universities will want to ensure that DUA terms
protect confidentiality when necessary, but permit appropriate publication and sharing
of research results in accordance with institution policies, applicable laws and regulations,
and federal requirements. DUAs are similar to confidentiality agreements.
- Debriefing [PDF]: Giving subjects previously undisclosed information about the research project following
completion of their participation in research. (Note that this usage, which occurs
within the behavioral sciences, departs from standard English, in which debriefing
is obtaining rather than imparting information).
- Deception in Research [PDF]: Deception is the intentional misleading of subjects or the withholding of full information
about the nature of a research experiment or procedure. Misleading or omitted information
might include the purpose of the research, the role of the researcher, or what procedures
in the study are actually experimental.
- Declaration of Helsinki: A code of ethics for clinical research approved by the World Medical Association
in 1964 and widely adopted by medical associations in various countries. It has been

not know which participants have been assigned which interventions. Typically, this
includes the investigator and participant.
- Efficacy: Indication that the clinical trial intervention produces a desired therapeutic effect
on the disease or condition under investigation.
- Eligibility Criteria: List of criteria guiding enrollment of participants into a study. The criteria describe
both inclusionary and exclusionary factors, (e.g. inclusion criterion - participants
must be between 55 and 85 years old; exclusion criterion – must not take drug X three
month prior to the study).
- Emergency Use: The FDA defines “emergency use” as the use of a test article on a human subject in
a life-threatening situation in which no standard acceptable treatment is available,
and in which there is not sufficient time to obtain IRB approval [21CFR 56.102 (d)].
- Exculpatory: Pertaining to that which relieves of a responsibility, obligation, or hardship; clearing
from accusation or blame.
- Expanded Access: A process regulated by the Food and Drug Administration (FDA) that allows manufacturers
to provide investigational new drugs to patients with serious diseases or conditions
who cannot participate in a clinical trial.
- Expedited Review [PDF]: Review of proposed research by the IRB Chairperson or a designated voting member
or group of voting members rather than by the entire IRB. Federal rules permit expedited
review for certain kinds of research involving no more than minimal risk and for minor
changes in approved research.
- Expired Study: When a continuing review of the research does not occur prior to the end of the approval
period specified by the IRB, IRB approval expires automatically. The study expires
on the date specified on the approval letter and the informed consent document. No
activities can occur on the expiration date or after.
- Federal-Wide Assurance (FWA): A standing agreement on file with the Office for Human Research Protections that
describes in detail the procedures it will use to protect the rights and welfare of
the human subjects.
- FERPA: (Family Education Rights and Privacy Act) was enacted in 1974. It is a set of regulations
that applies to those institutions that receive funding from the Department of Education.
FERPA was written specifically for students and guarantees them the right to inspect
and review their education records, the right to seek to amend education records,
and the right to have some control over the disclosure of information from those education
records. Departments may not release non-directory or personally identifiable information
about a student to a third party (parents included) without the student's written
- Food and Drug Administration (FDA): An agency within the U.S. Department of Health and Human Services (DHHS) responsible

a child to participate in research.
- Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule: The first comprehensive Federal protection for the privacy of personal health information.
The Privacy Rule regulates the way certain health care groups, organizations, or businesses,
called covered entities under the Rule, handle the individually identifiable health
information known as protected health information (PHI).
- Authorization: Permission from individuals to use or disclose their Protected Health Information;
generally required for research involving PHI. Certain statements are required; similar
to but in addition to the Common Rule's informed consent; can be added to a consent
form. (45 CFR 164.508)
- Covered Entity: Defined as health care providers who conduct certain financial and administrative
transactions electronically, such as billing and fund transfers; also, all health
plans and health care clearinghouses. (45 CFR 160.103) Covered Entities must comply
with HIPAA. (45 CFR 160.103 [PDF]).
The University of Utah's Covered Entity includes nearly all parts of the University
of Utah Health Sciences Center. Contact the HIPAA Regulatory Office (587-9241) or
go to Covered Entity for information on the University offices that are inside or outside the Covered

that identifies or could be used to identify the individual and is created or received
by a Covered Entity. (45 CFR 160.301, 164.501; information about the provision of
health care and payment for health care is included; some educational and employment
records are excluded.)
- Humanitarian Device Exemption: An HDE is a pre-market approval application submitted to the FDA (see also Investigational Device Exemption, Medical Device, Humanitarian Use Device [PDF]).
- Humanitarian Use Device (HUD): A Humanitarian Use Device (HUD) is a device that is intended to benefit patients
by treating or diagnosing a disease that affects fewer than 4,000 individuals in the
United States per year. To be considered for HUD status, a device sponsor must complete
a humanitarian device exemption (HDE) application with the FDA. An approved HDE application
authorizes the applicant to market the HUD. The labeling for the HUD must state that
the device is an HUD and that the effectiveness of the device has not been demonstrated.
- Human Participants: Individuals whose physiologic or behavioral characteristics and responses are the
object of study in a research project. Under the federal regulations, human participants
are defined as: living individual(s) about whom an Investigator conducting research
obtains: (1) data through intervention or interaction with the individual; or (2)
identifiable private information. NOTE: FDA's regulations define human subject as
an individual and do not use the adjective "living."
- Human Participants Research: This term applies to federally regulated research in which human participants (see
definition above), their data, tissue, genetic material or other is investigated in
a systematic fashion. It includes clinical trials, retrospective studies (subject
to IRB oversight or exempt from continuing IRB oversight), outcome studies, surveys,
- Human Subjects Research:According to IRB policy, research involving human subjects (participants) is defined
as any one of the following:
Research that does not meet the definition of research involving human subjects must
be determined by the IRB staff, not an individual investigator. Investigators must
complete and submit an IRB new study application with any applicable documents.
- Human subjects research subject to FDA regulation: Activities are human research subject to FDA regulations when they meet the FDA definition
of "clinical investigations" and involve a "subject" as defined in FDA regulation.
Under FDA regulation activities are "clinical investigations" when they involve:
In the above criteria "approved" means "approved by the FDA for marketing."
- Use of a drug other than the use of an approved drug in the course of medical practice
- Use of a medical device other than the use of an approved medical device in the course
of medical practice
- Gather data that will be submitted to or held for inspection by FDA in support of
a FDA marketing permit for a food, including a dietary supplement that bears a nutrient
content claim or a health claim, an infant formula, a food or color additive, a drug
for human use, a medical device for human use, a biological product for human use,
or an electronic product.
Under FDA regulations, individuals are considered "subjects" when they become a participant
in research, either as a recipient of the test article or as a control. If the research
involves a medical device, individuals are considered "subjects" when they participate
in an investigation, either as an individual on whom or on whose specimen an investigational
device is used or as a control.
- Human subjects research subject to DHHS regulation: Activities are human subject research subject to DHHS regulations when they meet
the DHHS definition of "research and involve a "subject" as defined in DHHS regulations.
Under DHHS regulations activities are "research" when they are a systematic investigation,
including research development, testing and evaluation, designed to develop or contribute
to generalizable knowledge.
Under DHHS regulations "subjects" means a living individual about whom an investigator
(whether professional or student) conducting research obtains (1) data through intervention
or interaction with the individual, or (2) identifiable private information.
Intervention includes both physical procedures by which data are gathered (for example,
venipuncture) and manipulations of the subject or the subject's environment that are
performed for research purposes.
Interaction included communication or interpersonal contact between investigator and
Private information includes information about behavior that occurs in a context in
which an individual can reasonably expect that no observation or recording is taking
place, and information which has been provided for specific purposes by an individual
and which the individual can reasonably expect will not be made public (for example,
a medical record). Private information must be individually identifiable (i.e., the
identity of the subject is or may readily be ascertained by the investigator or associated
with the information) in order for obtaining the information to constitute research
involving human subjects.
- Healthy Volunteer: A healthy volunteer is a person with no known significant health problems who participates
in clinical research to test a new drug, device, or intervention.
- Human In Vitro Fertilization: Any fertilization involving human sperm and ova that occurs outside the human body.
- Human Subject: A patient or healthy individual who is or becomes a participant in research, either
as a recipient of the intervention or as a control.
- International Conference on Harmonization of Technical Requirements for Registration
of Pharmaceuticals for Human Use (ICH): ICH guidance was published in the Federal Register on May 9, 1997 (62 FR 25692).
- Informed Consent: A process by which a participant or legal guardian voluntarily confirms his or her
willingness to participate in a particular research project, after having been informed
of all aspects of the research that are relevant to the subject's decision to participate.
Informed consent is documented by means of a written, signed, and dated informed consent
form approved by an IRB, unless such documentation is waived by the IRB (45 CFR 46).
A person's voluntary agreement, based upon adequate knowledge and understanding of
relevant information, to participate in research or to undergo a diagnostic, therapeutic,
or preventive procedure. In giving informed consent, subjects may not waive or appear
to waive any of their legal rights, or release or appear to release the investigator,
the sponsor, the institution or agents thereof from liability for negligence [Federal
Policy §116; 21 CFR 50.20 and 50.25] (OHRP).
- Informed Consent Form: A document that describes the rights of a study participant and provides details about
the study, such as its purpose, duration, required procedures, and key contacts. Risks
and potential benefits are explained in the informed consent document.
- Institutional Review Board (IRB)/Independent Ethics Committee (IEC): An independent body constituted of medical, scientific, and nonscientific members
whose responsibility it is to ensure the protection of the rights, safety, and well-being
of human subjects involved in a trial by, among other things, reviewing, approving,
and providing continuing review of trials, protocols and amendments, and of the methods
and material to be used to obtaining and documenting informed consent of the trial
- Intervention: A procedure or treatment such as a drug, nutritional supplement, gene transfer, vaccine,
behavior or device modification that is performed for clinical research purposes (45
CFR 46.102(f)). Interventions can also include noninvasive approaches such as surveys,
education, and interviews.
- Investigational Brochure (IB): In drug development, the Investigator's Brochure is a comprehensive document summarizing
the body of information about an investigational product or "study drug" obtained
during a drug trial. The IB is a document of critical importance throughout the drug
development process and is updated with new information as it becomes available. The
purpose of the IB is to compile data relevant to studies of the study drug in human
subjects gathered during preclinical and other clinical trials.
An IB is intended to provide the investigator with insights necessary for management
of study conduct and study subjects throughout a clinical trial. An IB may introduce
key aspects and safety measures of a clinical trial protocol, such as: dose (of the
study drug), frequency of dosing interval, methods of administration, and safety monitoring
An IB contains a "Summary of Data and Guidance for the Investigator" section, of which
the overall aim is to "provide the investigator with a clear understanding of the
possible risks and adverse reactions, and of the specific tests, observations, and
precautions that may be needed for a clinical trial. This understanding should be
based on the available physical, chemical, pharmaceutical, pharmacological, toxicological,
and clinical information on the investigational product(s). Guidance should also be
provided to the clinical investigator on the recognition and treatment of possible
overdose and adverse drug reactions that is based on previous human experience and
on the pharmacology of the investigational product".
The sponsor is responsible for keeping the information in the IB up-to-date. The IB
should be reviewed annually and must be updated when any new and important information
becomes available, such as when a drug has received marketing approval and can be
prescribed for use commercially.
- Investigational Device: According to the Food and Drug Administration (FDA), an investigational device is
a device, including a transitional device, that is the object of a [clinical] investigation
involving one or more subjects to determine the safety or effectiveness of the device
(21 CFR 812.3). Investigational use also includes clinical evaluation of certain modifications or new intended uses of legally marketed devices.
Also, see IDE Definitions and Acronyms for more definitions related to this term.
The use of an investigational device in human subjects requires approval by the IRB
and may also require approval from the FDA.
- Investigational Device Exemption (IDE): Exemptions from certain regulations found in the Medical Device Amendments that allow
shipment of unapproved devices for use in clinical investigations [21 CFR 812.20].
- Investigational Drug: According to the Food and Drug Administration (FDA), investigational new drug means
a new drug or biological drug that is used in a clinical investigation. The term also
includes a biological product that is used in vitro for diagnostic purposes. The terms
"investigational drug" and "investigational new drug" are deemed to be synonymous.
(21 CFR 312.3)
The use of an investigational drug (IND) in human subjects requires approval by the
FDA and the IRB.
An IND number is generally required for a drug (including a drug with marketing authorization)
if it is intended to:
An IND number may also be required for investigations that attempt to gain further
information about an approved use. The study sponsor and/or investigator cannot represent
(in a promotional context) that the drug is safe and effective for the purposes in
which it is under investigation.
- Support a new indication for use, establish safety or efficacy of the drug, support
a change in the approved route of administration (including method of assembly) or
- Support a change in the approved patient population (e.g. pediatric vs. adults) or
a population at greater/increased risk (e.g. immunocompromised, elderly, etc.);
- Support a change in the promotion/ advertising/ labeling/ packaging of an approved
- Investigational New Drug Application (IND): An IND is a request for authorization from the Food and Drug Administration (FDA)
to administer an investigational drug or biological product to humans. Such authorization
must be secured prior to interstate shipment and administration of any new drug or
biological product that is not the subject of an approved New Drug Application or
Biologics/Product License Application (21 CFR 312).
- Investigational New Drug (IND) or Device (IDE): A drug or device permitted by FDA to be tested in humans but not yet determined to
be safe and effective for a particular use in the general population and not yet licensed
for marketing (Also, see Investigational Device Exemption (IDE)).
- Investigator's Brochure: A compilation of the clinical and non-clinical data on the investigational product(s)
that is relevant to the study of the investigational product(s) in human subjects.
- In Vitro: Literally, "in glass" or "test tube;" used to refer to processes that are carried
out outside the living body, usually in the laboratory, as distinguished from in vivo.
- In Vivo: Literally, "in the living body;" processes, such as the absorption of a drug by the
human body, carried out in the living body rather than in a laboratory (in vitro).
- Legally Authorized Representative (LAR): A person authorized either by statute or by court appointment to make decisions on
behalf of another person. In human subject research, an individual or judicial or
other body authorized under applicable law to consent on behalf of a prospective subject
to the subject's participation in the procedure(s) involved in the research. There are several considerations that must be addressed when the inclusion of an LAR
is proposed, such as, whether periodic re-consenting is warranted, and whether the
probability of benefit is greater than the probability of harm.
- Limited Data Set:A limited data set could include the following (potentially identifying) information:
Covered entities must condition the disclosure of the limited data set on execution
of a "data use agreement," which
- Admission, discharge, and service dates;
- Dates of birth and, if applicable, death;
- Age (including age 90 or over); and
- Five-digit zip code or any other geographic subdivision, such as state, county, city,
precinct and their equivalent geocodes (except street addresses).
In addition, the data use agreement must contain adequate assurances that the recipient
will use appropriate physical, technical and administrative safeguards to prevent
use or disclosure of the limited data set other than as permitted by HIPAA and the
data use agreement, or as required by law.
- establishes the permitted uses and disclosures of such information by the recipient,
consistent with the purposes of research, public health, or health care operations;
- limits who can use or receive the data; and
- requires the recipient to agree not to re-identify the data or contact the individuals.
- Longitudinal Study: A study designed to follow subjects forward through time.
- Manual of Procedures (MOP): A set of procedures describing study conduct. A MOP is developed to facilitate consistency
in protocol implementation and data collection across study participants and clinical
- Masking/Blinding: A procedure in which the investigator administering the assessments and intervention
as well as the participants in a clinical trial are kept unaware of the treatment
assignment(s). Single blinding usually refers to the study participant(s) being unaware,
and double blinding usually refers to the study participant(s) and any of the following
being unaware of the treatment assignment(s): investigator(s), monitor, and data analyst(s).
- Material Transfer Agreement: A Material Transfer Agreement (MTA) is a document that is used by scientists and
their institutions to transfer materials to other scientists and institutions. MTAs
provided by outside organizations may contain clauses that are not consistent with
the University of Utah policies and procedures and/or federal law. Signing one of
these agreements could severely impede a scientist's ability to carry out his or her
research or to publish in a timely fashion. It is important that all MTAs are evaluated
and signed by an authorized TVC representative. The Technology Venture Commercialization
Office handles and processes these agreements.
- Medical Device: According to the FDA, a device is: "An instrument, apparatus, implement, machine,
contrivance, implant, in vitro reagent, or other similar or related article, including
a component part, or accessory which is:
- recognized in the official National Formulary, or the United States Pharmacopoeia,
or any supplement to them,
- intended for use in the diagnosis of disease or other conditions, or in the cure,
mitigation, treatment, or prevention of disease, in man or other animals, or
- intended to affect the structure or any function of the body of man or other animals,
and which does not achieve any of it's primary intended purposes through chemical
action within or on the body of man or other animals and which is not dependent upon
being metabolized for the achievement of any of its primary intended purposes." (See:
Is The Product A Medical Device?).
- Metabolism (of a drug): The manner in which a drug is acted upon (taken up, converted to other substances,
and excreted) by various organs of the body.
- Minimal Risk: Minimal risk means that the probability and magnitude of harm or discomfort anticipated
in the research are not greater in and of themselves than those ordinarily encountered
in daily life or during the performance of routine physical or psychological examinations
or tests (45 CFR 46.102(i)). For example, the risk of drawing a small amount of blood
from a healthy individual for research purposes is no greater than the risk of doing
so as part of routine physical examination. This is not interpreted to include the
inherent risks certain categories of human subjects face in their everyday lives.
For example, the risks imposed in research focused on a special population should
not be evaluated against the inherent risks encountered in their work environment
(e.g., emergency responder, pilot, soldier in a combat zone).
In addition, the IRB generally subscribes to the recommendations related to 45 CFR 46.404 from SACHRP regarding research involving children.
- New Drug Application (NDA): An application submitted by the manufacturer of a drug to the FDA, after the clinical
trial has been completed, for a license to market the drug for a specified indication.
- NIH: National Institutes of Health: a federal agency within the Public Health Service,
DHHS, comprising 21 institutes and centers. It is responsible for carrying out and
supporting biomedical and behavioral research.
- Non-Affiliated Member: Member of an Institutional Review Board who has no ties to the parent institution,
its staff, or faculty. This individual is usually from the local community (e.g.,
minister, business person, attorney, teacher, homemaker).
- Non-Inferiority Design: A non-inferiority trial compares a test treatment to a control treatment of established
effectiveness and seeks to show that the test treatment is not materially worse than
or inferior to the control treatment. A non-inferiority trial seeks to show that any
difference between the two treatments is small enough to allow a conclusion that the
test treatment has at least some effect or, in many cases, an effect that is not significantly
less than the active control. A non-inferiority trial may proceed under 21 CFR 50.24
if it meets the requirements of the regulation.
For a non-inferiority trial to be informative, there would need to be clear data about
the effectiveness of the control treatment (to make the non-inferiority study interpretable)
and about known safety or other problems associated with the control treatment. Non-inferiority
trials are generally used in situations where a placebo-controlled trial would be
unethical and where there are no data to suggest the new treatment would be more effective
than the standard treatment.
- Non-Therapeutic Research: Research that has no likelihood or intent of producing a diagnostic, preventive,
or therapeutic benefit to the current subjects, although it may benefit subjects with
a similar condition in the future.
- Non-Viable Fetus: An expelled or delivered fetus which, although it is living, cannot possibly survive
to the point of sustaining life independently, even with the support of available
medical therapy [45 CFR 46.203 (d) and (e)]. Although it may be presumed that an expelled
or delivered fetus is nonviable at a gestational age less than 20 weeks and weight
less than 500 grams [Federal Register 40 (August 8, 1975): 33552], a specific determination
as to viability must be made by a physician in each instance. (See also: Viable Infant.)
- Null Hypothesis: The proposition, to be tested statistically, that the experimental intervention has
"no effect," meaning that the treatment and control groups will not differ as a result
of the intervention. Investigators usually hope that the data will demonstrate some
effect from the intervention, thereby allowing the investigator to reject the null
- Nuremberg Code: A code of research ethics developed during the trials of Nazi war criminals following
World War II and widely adopted as a standard during the 1950s and 1960s for protecting
- Observational Study: A clinical study in which participants identified as belonging to study groups are
assessed for biomedical or health outcomes. Participants may receive diagnostic, therapeutic,
or other types of interventions, but the investigator does not assign participants
to specific interventions (as in an interventional study).
- Office for Human Research Protections (OHRP): A federal government agency within the Department of Health and Human Services (DHHS)
charged with the protection of human subjects participating in government funded research.
It issues assurances and oversees compliance of regulatory guidelines by research
- Office of Sponsored Projects (OSP): The Office of Sponsored Projects is responsible for preparing, interpreting, negotiating,
and executing agreements on behalf of the University of Utah for projects funded by
federal and state agencies, foundations, and other public and private sources. They
also draft, negotiate, and execute awards and sub-awards for collaborative research.
- Open-Label (Open-Label Trial): Describes a clinical trial in which masking is not used. This means that all parties
involved with the trial know which participants have been assigned which interventions.
- Parallel Design: Describes a clinical trial in which two or more groups of participants receive different
interventions. For example, a two-arm parallel design involves two groups of participants.
One group receives drug A, and the other group receives drug B. So during the trial,
participants in one group receive drug A "in parallel" to participants in the other
group who receive drug B.
- Parental Permission: The agreement of parent(s) or guardian to the participation of their child or ward
in research [45 CFR 46.402(c)].
- Pharmacokinetics (PK): The process (in a living organism) of absorption, distribution, metabolism, and excretion
of a drug or vaccine.
- Pharmacology: The scientific discipline that studies the action of drugs on living systems (animals
or human beings).
- Phase 1, Phase 2, Phase 3, Phase 4 Clinical Trial: See "Clinical Trial".
- Phenotype: The physical manifestation of a gene function.
- Placebo: A placebo is an inactive pill, liquid, powder, or other intervention that has no
treatment value. In clinical trials, experimental treatments are often compared with
placebos to assess the treatment's effectiveness.
A method of investigation in which an inactive substance/treatment (the placebo) is
given to one group of participants, while the test article is given to another group.
The results obtained in the two groups are then compared to see if the investigational
treatment is more effective in treating the condition.
- Principal Investigator (PI): The person who is responsible for the scientific and technical direction of the entire
clinical study (for example, for all sites of a multisite study).
- Prisoners [PDF]: An individual involuntarily confined in a penal institution, including persons: (1)
sentenced under a criminal or civil statue; (2) detained pending arraignment, trial,
or sentencing; and (3) detained in other facilities (e.g., for drug detoxification
or treatment of alcoholism) under statutes or commitment procedures providing such
alternatives to criminal prosecution or incarceration in a penal institution. The
definition of "minimal risk" for research involving prisoners differs somewhat from
that given for non-institutionalized adults.
- Privacy: Control over the extent, timing, and circumstances of sharing oneself (physically,
behaviorally, or intellectually) with others.
- Proband: The person whose case serves as the stimulus for the study of other members of the
family to identify the possible genetic factors involved in a given disease, condition,
- Prophylactic: Preventive or protective; a drug, vaccine, regimen, or device designed to prevent,
or provide protection against, a given disease or disorder.
- Prospective Studies: Studies designed to observe outcomes or events that occur subsequent to the identification
of the group of subjects to be studied. Prospective studies need not involve manipulation
or intervention but may be purely observational or involve only the collection of
- Protocol: A document that describes the objective(s), design, methodology, statistical consideration,
and organization of a trial.
- Protocol Amendments: A written description of a change(s) to or formal clarification of a protocol.
- Protocol Deviations: Failure to conduct a study as described in the protocol. The failure may be accidental
or due to negligence and in either case, the protocol deviation should be documented.
This also includes failure to comply with federal laws and regulations, the institution's
commitments and policies, and standards of professional conduct and practice. Examples
of noncompliance include:
- failure to obtain/maintain approval for research,
- failure to obtain informed consent when required,
- failure to file adverse event reports,
- performance of an unapproved study procedure,
- performance of research at an unapproved site,
- failure to file protocol modifications and
- failure to adhere to an approved protocol.
- Protocol Deviation Report: Internal document created as part of the ongoing quality control process summarizing
compliance with the protocol and listing protocol deviations and/or violations.
- Protocol Review and Monitoring Committee (PRMC): The Protocol Review and Monitoring Committee (PRMC) was formed in 1993 to comply
with National Cancer Institute guidelines in establishing a scientific review and
monitoring system of cancer studies - it is a mechanism for quality assurance. The
PRMC membership includes faculty, statisticians, pharmacy, imaging, patient advocate,
research nurse and other ad hoc reviewers from various disciplines within the Health
Sciences. The PRMC reviews cancer-related protocols for scientific merit and progress,
including participant accrual. It also prioritizes cancer protocols that may compete
for the same patient population. Its function is complementary to that of the Institutional
Review Board, which focuses on the protection of human subjects in research. If a
study is designed to involve cancer patients, it must receive PRMC approval before
it can be IRB approved. If a study includes cancer patients by default (as part of
a broader patient population) and not by study design, it doesn't need PRMC review.
- Protected Health Information (PHI): Information about the past, present, or future physical or mental health of an individual
that identifies or could be used to identify the individual and is created or received
by a Covered Entity. (45 CFR 160.301, 164.501; information about the provision of
health care and payment for health care is included; some educational and employment
records are excluded.)
- Protocol Summary: This document is completed by the PI and includes a summary of the protocol or can
be the study plan for the entire study. Protocol summaries are required for all studies
submitted to the IRB.
- Quality Assurance/Quality Improvement (QA/QI): These are activities designed to improve the quality of a process or assess its overall
function. Such activities do not satisfy the definition of “research” under 45 CFR
46.102(d), which is “…a systematic investigation, including research development,
testing and evaluation, designed to develop or contribute to generalizable knowledge…”
Therefore the HHS regulations for the protection of human subjects do not apply to
such quality improvement activities, and there is no requirement under these regulations
for such activities to undergo review by an IRB, or for these activities to be conducted
with provider or patient informed consent.
The clinical, practical, or administrative uses for such performance measurements
and reporting could include, for example, helping the public make more informed choices
regarding health care providers by communicating data regarding physician-specific
surgical recovery data or infection rates. Other practical or administrative uses
of such data might be to enable insurance companies or health maintenance organizations
to make higher performing sites preferred providers, or to allow other third parties
to create incentives rewarding better performance.
- Radioactive Drug Research Committee (RDRC): An institutional committee responsible for the use of radioactive drugs in human
subjects for research purposes. Research involving human subjects that proposes to
use radioactive drugs must meet various FDA requirements, including limitations on
the pharmacological dose and the radiation dose. Furthermore, the exposure to radiation
must be justified by the quality of the study and the importance of the information
it seeks to obtain. The committee is also responsible for continuing review of the
drug use to ensure that the research continues to comply with FDA requirements, including
reporting obligations. The committee must include experts in nuclear medicine and
the use of radioactive drugs, as well as other medical and scientific members [21
The University of Utah's radiation safety program is designed to prevent unnecessary
radiation exposures, and to control those that are necessary. RDRC is an ancillary
committee to the University of Utah Institutional Review Board, which is responsible
for the review and approval of research protocols involving human participants and
radiation exposure, and the administration or use of radioactive drugs. Clinical investigations
that include exposing human participants to radiation (x-rays, etc.) require RDRC
approval before IRB approval may be granted.
- Radiopaque Contrast Agents: Materials that stop or attenuate radiation that is passed through the body, creating
an outline on film of the organ(s) being examined. Contrast agents, sometimes called
"dyes," do not contain radioisotopes. When such agents are used, exposure to radiation
results only from the X-ray equipment used in the examination. The chemical structure
of radiopaque contrast agents can produce a variety of adverse reactions, some of
which may be severe — and possibly life-threatening — in certain individuals.
- Randomization: The process of assigning clinical trial participants to treatment or control groups
using an element of chance (e.g. like flipping a coin) to determine the assignments
in order to reduce bias.
- Recombinant DNA Technology: "The ability to chop up DNA, the stuff of which genes are made, and move the pieces,
[which] permits the direct examination of the human genome," and the identification
of the genetic components of a wide variety of disorders [Holtzman (1989), p. 1].
Recombinant DNA technology is also used to develop diagnostic screens and tests, as
well as drugs and biologics for treating diseases with genetic components.
- Recruitment Plan: The plan that outlines how individuals will be recruited for the study and how the
study will reach the recruitment goal.
- REM: Acronym for Roentgen Equivalent in Man; the unit of measurement for a dose of an
ionizing radiation that produces the same biological effect as a unit of absorbed
does (1 rad) of ordinary X-rays. One millirem is equal to 1/1000 of a rem.
- Remission: A period in which the signs and symptoms of a disease are diminished or in abeyance.
The term "remission" is used when one cannot say with confidence that the disease
has been cured.
- Remuneration: Payment for participation in research. (NOTE: It is wise to confine use of the term
"compensation" to payment or provision of care for research-related injuries.)
- Research Involving a Human Being as an Experimental Subject: According to the Department of Defense Directive 3216.02 section E2.1.3., this means
an activity, for research purposes, where there is an intervention or interaction
with a human being for the primary purpose of obtaining data regarding the effect
of the intervention or interaction. Examples of interventions or interactions include,
but are not limited to, a physical procedure, a drug, a manipulation of the subject
or subject's environment, the withholding of an intervention that would have been
undertaken if not for the research purpose. This does not include: (1) Activities
carried out for purposes of diagnosis, treatment, or prevention of injury and disease
in members of the armed Forces and other mission essential personnel under Force Health
Protection programs of the Department of Defense. (2) Authorized health and medical
activities as part of the reasonable practice of medicine or other health professions.
(3) Monitoring for compliance of individuals and organizations with requirements applicable
to military, civilian, or contractor personnel or to organizational units. This includes
such activities as drug testing, occupational health and safety monitoring, and security
- Respect for Persons: An ethical principle discussed in the Belmont Report requiring that individual autonomy
be respected and persons with diminished autonomy be protected.
- Retention Plan: The plan that details the methods in which the study will use in order to retain
study participation in the clinical trial.
- Retrospective Study: Research conducted by reviewing records from the past (e.g., birth and death certificates,
medical records, school records, or employment records) or by obtaining information
about past events elicited through interviews or surveys. Case control studies are
an example of this type of research.
- Risk Determinations: The probability of harm or injury (physical, psychological, social, or economic) occurring
as a result of participation in a research study. Both the probability and magnitude
of possible harm may vary from minimal to significant. Federal regulations define
only "minimal risk." (See also: Minimal Risk.) These can include:
- Moderate Risk: The subject will undergo procedures that will increase their risks above those normally
encountered in daily life. Equivalent term is "more than minimal risk." These can
include, but are not limited to: clinical drug trials, device trials, genetic studies,
and risks that include insurability and employability.
- Minimal Risk: The subject will undergo procedures that do not appear to increase the risks above
those normally encountered in daily life. These can include but are not limited to
studies that involve survey, questionnaire, interview, medical records review, observation
of behaviors, drawing a small amount of blood from a healthy individual, etc.
- Exempt: These studies are not usually reviewed by board members, but are reviewed by the
chairman. These have been determined to fit certain federal regulations as exempt
from IRB review.
- Safe Harbor De-Identification [PDF]: Potential identifiers include obvious ones like name and social security number, and
Under HIPAA's "safe harbor" standard, information is considered de-identified if all
of the above have been removed, and there is no reasonable basis to believe that the
remaining information could be used to identify a person.
- All geographic subdivisions smaller than a state, including street address, city,
county, precinct, zip code, and their equivalent geocodes, except for the initial
three digits of a zip code if, according to the current publicly available data from
the Bureau of the Census: the geographic unit formed by combining all zip codes with
the same three initial digits contains more than 20,000 people; and [t]he initial
three digits of a zip code for all such geographic units containing 20,000 or fewer
people is changed to 000.
- All elements of dates (except year) for dates directly related to an individual, including
birth date, admission date, discharge date, date of death; and all ages over 89 and
all elements of dates (including year) indicative of such age, except that such ages
and elements may be aggregated into a single category of age 90 or older;
- Voice and fax telephone numbers;
- Electronic mail addresses;
- Medical record numbers, health plan beneficiary numbers, or other health plan account
- Certificate/license numbers;
- Vehicle identifiers and serial numbers, including license plate numbers;
- Device identifiers and serial numbers
- Internet Protocol (IP) address numbers and Universal Resource Locators (URLs);
- Biometric identifiers, including finger and voice prints;
- Full face photographic images and any comparable images; and
- Any other unique identifying number, characteristic, or code.
- Screening Log: An essential document that records all individuals who entered the screening process.
The screening log demonstrates the investigator’s attempt to enroll a representative
sample of participants.
- Screening Process: A process designed to determine individual’s eligibility for participation in a
clinical research study.
- Secondary Data: Secondary data is data collected by someone other than the user. Common sources of
secondary data for social science include censuses, surveys, organizational records
and data collected through qualitative methodologies or qualitative research. Primary
data, by contrast, are collected by the investigator conducting the research.
- Serious Adverse Event (SAE): Any adverse event that:
Is another condition which investigators judge to represent significant hazards
- Results in death
- Is life threatening, or places the participant at immediate risk of death from the
event as it occurred
- Requires or prolongs hospitalization
- Causes persistent or significant disability or incapacity
- Results in congenital anomalies or birth defects
- Sham Comparator Arm: A group of participants that receives a procedure or device that is made to be indistinguishable
from the actual procedure or device being studied but does not contain active processes
- Short Form Consent Document: The Short Form was created in an effort to increase the University's compliance with
regard to non-English speaking participants. The regulations state that informed consent
information should be presented "in a language understandable to the subject", and
in most situations, that informed consent be documented in writing. This means that
participants who do not speak English should be presented with a consent document
written in a language understandable to them. Any time a study proposes to use the
Short Form as an alternative consent process, the form and the process must be approved
by the convened board. The Board should determine whether or not the process is adequate
and appropriate for the study, or if a fully-translated consent document should be
- Source Document: Original documents, data, and records (e.g., hospital records, clinical and office
charts, laboratory notes, memoranda, participant diaries, recorded data from automated
instruments, x-rays, etc.) that are used in a clinical trial.
- Sponsor-Investigator: An individual who both initiates and actually conducts - alone or with others - a
clinical investigation. Corporations, agencies, or other institutions do not qualify
- Standard Operating Procedures (SOPs): Detailed written instructions to achieve uniformity of the performance of a specific
function across studies and patients at an individual site.
- Stopping Rules: Established safety criteria that would either pause or halt a study due to reasons
including but not limited to futility or risk(s) to the participants.
- Stratification: Separation of a study cohort into subgroups or strata according to specific characteristics
such as age, gender, etc., so that factors which might affect the outcome of the study,
can be taken into account.
- Technology & Venture Commercialization Office (TVC): The Technology & Venture Commercialization Office (TVC) at the University of Utah
has managed the University's intellectual property developed by faculty, staff and
students since 1967. Through the establishment of commercial partnerships with industry
and the development of products from these technologies, the TVC benefits the public
and promotes economic growth.
- Tissue/Specimen Banking: Specimen collection banks, whether they are described as "banks" or not, are many
and varied. They cover the spectrum from individual clinicians' research specimen
collections, (often gathered with no specific project in mind) to institutional "Tissue
Banks" (such as cancer center shared resource banks) to multi-center, industry-sponsored
drug trials which usually collect at least some blood or tissue for unspecified future
- Tracked Changes: In word processing, track changes is an editing command that is commonly used when
you create an original document and make changes and want to keep track of the changes
that are made to that original document. It is also a useful tool for collaborating
on a document, as it allows multiple users to make revisions without losing the context
of the original document.Changes to text and formatting are noted in a number of different
ways, depending on the word processing software you use. Tracking changes allows the
IRB staff and board members to clearly see what changes, modifications, updates, and
additions have been made to study documents. For a tutorial on how to track changes
in a document, please go to the A-Z Index page
- Translation Certification Letter [DOC]: Certifies the authenticity of the translation of a translated Consent Document. A
reference template for the Translation letter can be found on the IRB website.
- Unanticipated Problem (UP):Unanticipated problems are defined as any incident, experience or outcome that occurs
during the course of a study that meets all of the following criteria:
- Unforeseen (not expected by the researcher or the research participant) given the
research procedures and the subject population being studied.
- Related or probably related to participation in the research or if the event or problem
probably or definitely affects the safety, rights and welfare of current participants;
- Suggests that the research places subjects or others at a greater risk of harm (including
physical, psychological, economic or social harm) than was previously known or recognized.
- Unmasking/Unblinding: A procedure in which one or more parties to the trial are made aware of the treatment
- Utah Population Database (UPDB): The Utah Population Database (UPDB) at the University of Utah is one of the world’s
richest sources of in-depth information that supports research on genetics, epidemiology,
demography, and public health. For more than 30 years, researchers at the University
of Utah and other institutions have used UPDB to identify and study individuals and
families that have higher than normal incidence of cancer or other diseases, to analyze
patterns of genetic inheritance, and to identify specific genetic mutations. In addition,
demographic studies have shown trends in fertility transition and changes in mortality
patterns for both infants and adults.
The central component of the UPDB is an extensive set of Utah family histories, in
which family members are linked to demographic and medical information. The UPDB includes
diagnostic records about cancer, cause of death, and medical details associated with
births. It also includes claims data from statewide inpatient hospital discharge records
as well as ambulatory surgery records from hospital outpatient departments and ambulatory
surgery centers. The UPDB provides access to information on more than 7.3 million
individuals and supports over 100 research projects. This information can only be
used for biomedical and health-related research.
Support for the UPDB is provided by the Pedigree and Population Resource (PPR), which
is directed by Ken R. Smith, PhD. The Utah Resource for Genetic and Epidemiologic
Research (RGE) and an Institutional Review Board (IRB) administer access to files
through a review process. PPR is supported by Huntsman Cancer Institute as well as
the University of Utah. RGE and the IRB are administered through the Office of the
Vice President for Research at the University of Utah.
- Viable Infant: When referring to a delivered or expelled fetus, the term "viable infant" means likely
to survive to the point of sustaining life independently, given the benefit of available
medical therapy [45 CFR 46.203(d)]. This judgment is made by a physician. In accordance
with DHHS regulations, the Secretary, HHS, may publish guidelines to assist in the
determination of viability. Such guidelines were published in 1975, and specify an
estimated gestational age of 20 weeks or more and a body weight of 500 grams or more
as indices of fetal viability [Federal Register 40 (August 8, 1975): 33552]. These
indices depend on the state of present technology and may be revised periodically.
(See also: Nonviable Fetus.)
- Vulnerable Populations: Individuals whose willingness to volunteer in a clinical trial may be unduly influenced
by the expectation, whether justified or not, of benefits associated with participation,
or of a retaliatory response from senior members of a hierarchy in case of refusal
to participate. Examples are members of a group with a hierarchical structure, such
as medical, pharmacy, dental and nursing students, subordinate hospital and laboratory
personnel, employees of the pharmaceutical industry, members of the armed forces,
and persons kept in detention. Other vulnerable subjects include patients with incurable
diseases, persons in nursing homes, unemployed or impoverished persons, and patients
in emergency situations, ethnic minority groups, homeless persons, nomads, refugees,
minors, and those incapable of giving consent.
