recording, and reporting trials that involve the participation of
human subjects. It details the responsibilities of all parties,
including the IRB/IEC.
Question 2
What is the primary purpose of obtaining "informed consent" from a research
participant?
A) To get the participant's signature on a legal document.
B) To ensure the participant fully understands the study procedures, risks,
benefits, and alternatives, and voluntarily agrees to participate.
C) To transfer all liability for risks to the participant.
D) To guarantee the participant will complete the entire study.
E) To collect demographic data.
Correct Answer: B) To ensure the participant fully understands the
study procedures, risks, benefits, and alternatives, and voluntarily
agrees to participate.
Rationale: Informed consent is an ethical and regulatory requirement
that upholds participant autonomy by ensuring they make a
,knowledgeable and voluntary decision about participating in
research.
Question 3
Which federal regulation governs the use of investigational new drugs (INDs)
in clinical trials?
A) 21 CFR Part 11
B) 21 CFR Part 50
C) 21 CFR Part 56
D) 21 CFR Part 312
E) 21 CFR Part 812
Correct Answer: D) 21 CFR Part 312
Rationale: 21 CFR Part 312 outlines the regulations for
Investigational New Drug Applications (INDs), which are required for
clinical investigations of unapproved drugs.
Question 4
What is the primary role of the "Investigator's Brochure (IB)"?
A) To provide participant recruitment information.
B) To document adverse events during a study.
C) To compile the complete medical history of a participant.
D) To provide comprehensive information about the investigational product
to the investigators and IRB/IEC.
E) To serve as the study protocol.
Correct Answer: D) To provide comprehensive information about the
investigational product to the investigators and IRB/IEC.
Rationale: The IB is a compilation of the clinical and nonclinical data
on the investigational product(s) that is relevant to the study of the
product(s) in human subjects. It provides the information necessary
to understand the rationale for, and to comply with, many features
of the protocol.
,Question 5

A) Any expected side effect of the investigational product.
B) Any untoward medical occurrence in a patient or clinical investigation
subject administered a pharmaceutical product, regardless of causality.
C) Only events directly caused by the investigational product.
D) Events that lead to study withdrawal.
E) Events that only occur in the control group.
Correct Answer: B) Any untoward medical occurrence in a patient or
clinical investigation subject administered a pharmaceutical
product, regardless of causality.
Rationale: This is the broad definition of an AE. Causality is
assessed after the event, but the initial reporting includes all
untoward occurrences.
Question 6
What is the purpose of "source documents" in a clinical trial?

B) To serve as the original records of all study data and observations.
C) To provide information about the investigational product.
D) To document IRB/IEC approvals.
E) To provide a summary of the study protocol.
Correct Answer: B) To serve as the original records of all study data
