Research Study Closure 10% ~10 questions
SECTION 1: Research Study Start-Up (40% of Exam)
Topic: Regulatory Requirements & IRB/IEC
Question 1
Which historical document established the principle that voluntary consent of the
human subject is absolutely essential for ethical research?
A) The Declaration of Helsinki
B) The Nuremberg Code
C) The Belmont Report
D) The Common Rule
Rationale: The Nuremberg Code (1947) was the first international document to
establish ethical principles for human experimentation. Its first principle states that
the voluntary consent of the human subject is absolutely essential, arising directly
from the Nuremberg Trials of Nazi doctors who conducted experiments on
concentration camp prisoners. While the Declaration of Helsinki (1964) and
Belmont Report (1979) are also foundational ethical documents, the Nuremberg
Code was first to establish this principle.
,Question 2
Under 21 CFR Part 56, what is the minimum number of members required for an
Institutional Review Board (IRB)?
A) Three members
B) Five members
C) Seven members
D) Nine members
Rationale: According to 21 CFR 56.107, an IRB must have at least five
members with varying backgrounds to promote complete and adequate review of
research activities. The membership must include at least one member whose
primary concerns are scientific and one whose primary concerns are nonscientific,
as well as at least one member who is not affiliated with the institution.
Question 3
Which federal regulation governs the protection of human subjects in clinical
research conducted or supported by U.S. Department of Health and Human
Services?
A) 21 CFR Part 11
B) 45 CFR Part 46
C) 21 CFR Part 312
D) 42 CFR Part 493
Rationale: 45 CFR Part 46 is the federal regulation that governs the protection of
human subjects in research conducted or supported by the U.S. Department of
Health and Human Services (HHS). It is often referred to as the "Common Rule."
21 CFR Part 11 governs electronic records and signatures; 21 CFR Part 312
governs investigational new drug applications; and 42 CFR Part 493 governs
laboratory requirements.
Question 4
What is the primary purpose of an Investigational New Drug (IND) application
submitted to the FDA?
A) To market a new drug
B) To obtain permission to administer an investigational drug to humans in a
,clinical trial
C) To report adverse events
D) To obtain IRB approval
Rationale: An IND application is submitted to the FDA to obtain permission to
administer an investigational drug to humans in a clinical trial. It must contain pre-
clinical data, manufacturing information, and the clinical trial protocol. The IND
must be in effect before a clinical trial can begin.
Question 5
A clinical research coordinator is obtaining informed consent from a potential
study participant. Which of the following is NOT a required element of informed
consent under 21 CFR 50.25?
A) A statement that participation is voluntary and the participant may withdraw at
any time
B) A description of any foreseeable risks or discomforts
C) A guarantee that the participant will receive the experimental treatment
D) An explanation of whom to contact for answers to pertinent questions
Rationale: A guarantee that the participant will receive the experimental
treatment is NOT a required element of informed consent. Informed consent must
include a statement that participation is voluntary, a description of foreseeable
risks, and contact information for questions. However, participants cannot be
guaranteed to receive experimental treatment as they may be randomized to a
control group or placebo.
Question 6
What is the primary responsibility of the Principal Investigator (PI) in a clinical
trial?
A) To manage the study budget
B) To ensure the trial is conducted in accordance with the protocol, GCP, and
applicable regulations
C) To obtain informed consent from all participants
D) To monitor the data for quality
, Rationale: The Principal Investigator (PI) is ultimately responsible for the
conduct of a clinical trial at a site. This includes ensuring the trial is conducted in
accordance with the protocol, Good Clinical Practice (GCP), and all applicable
regulations. While the PI may delegate tasks, ultimate responsibility cannot be
delegated.
Question 7
Which of the following documents must be submitted to an IRB for initial review
of a new clinical trial?
A) Only the protocol
B) Protocol, informed consent form, investigator's brochure, and any other
relevant documents
C) Only the informed consent form
D) Only the FDA Form 1572
Rationale: For initial IRB review, the submission must include the protocol,
informed consent form, investigator's brochure, and any other relevant
documents such as advertisements, questionnaires, and investigator agreements.
The IRB needs comprehensive information to conduct a full review of the risks and
benefits of the research.
Question 8
What is the difference between an IRB and an IEC?
A) There is no difference; they are the same
B) IRB is the term used in the U.S.; IEC (Independent Ethics Committee) is
the term used internationally
C) IRB reviews only drugs; IEC reviews only devices
D) IRB is for academic research; IEC is for industry research
Rationale: IRB (Institutional Review Board) is the term used in the United
States under FDA and HHS regulations, while IEC (Independent Ethics
Committee) is the term used internationally, particularly in the context of ICH
GCP guidelines. Both serve the same fundamental purpose: reviewing and
approving research involving human subjects to protect their rights and welfare.
