GCP Sample Questions and Answers

Question 1.

A pharmaceutical company is preparing to launch a multinational Phase III clinical trial. During a monitoring visit, a Clinical Research Associate discovers that one investigator has delegated informed consent discussions to a study coordinator who is not listed on the site’s delegation log and has not completed protocol-specific training. Several participants have already been enrolled.

What should be the CRA’s most appropriate immediate action?

A. Ignore the issue because the principal investigator remains responsible for the study.

B. Document the finding, notify the investigator, and escalate according to the sponsor’s procedures for assessment and corrective actions.

C. Remove all enrolled participants from the study immediately.

D. Continue monitoring and report the issue only if another violation occurs.

Correct Answer: B

Answer Explanation:
ICH Good Clinical Practice (GCP) requires investigators to maintain an accurate delegation log showing who performs trial-related duties. Individuals performing study responsibilities must be qualified through education, training, and experience. The CRA should document the deviation, discuss it with the investigator, and follow the sponsor’s escalation process to determine participant impact and whether corrective and preventive actions (CAPA) are necessary. Immediate participant removal is rarely appropriate without a formal assessment. Ignoring the issue or delaying reporting could place participant rights and data integrity at risk. The principal investigator remains ultimately responsible, but responsibilities must only be delegated to qualified and documented personnel.

Question 2.

A participant signs the informed consent form before any study procedures. During a routine audit, it is discovered that the participant signed an outdated version of the consent document that had already been replaced following an ethics committee approval of new safety information.

What is the best course of action?

A. Continue participation because consent was already obtained.

B. Exclude all participant data from the trial.

C. Inform the participant of the updated information and obtain consent using the currently approved version as soon as possible.

D. Ask the participant to sign the old form again with the current date.

Correct Answer: C

Answer Explanation:
Participants must receive the most current approved information before deciding whether to continue participation in a clinical trial. When new safety information or protocol changes require an updated informed consent document, participants enrolled using an outdated version should be re-consented promptly using the latest ethics committee-approved form. This ensures that participants can make an informed decision with complete and current information. Simply allowing participation to continue without updated consent violates GCP principles. Re-signing an obsolete form does not correct the issue, and excluding data is generally unnecessary unless required after evaluating the protocol deviation and regulatory requirements.

Question 3.

During source data verification, a monitor notices that blood pressure values recorded in the electronic case report form differ from those documented in the participant’s medical record.

Which source should generally be considered the primary reference for verification?

A. Electronic Case Report Form (eCRF)

B. Sponsor database

C. Source medical records

D. Statistical analysis dataset

Correct Answer: C

Answer Explanation:
Source documents are the original records containing clinical findings, observations, and participant information. These may include medical charts, laboratory reports, imaging records, or electronic health records. The eCRF is intended to accurately reflect data transcribed from source documents unless direct data capture is permitted by the protocol. During monitoring, discrepancies between source documents and the eCRF must be investigated and corrected following sponsor procedures. Source documentation supports participant safety, protocol compliance, and data credibility. Statistical datasets and sponsor databases are derived from collected study data and cannot replace original source records during verification.

Question 4.

A Phase II oncology study allows enrollment only after confirmation that all inclusion and no exclusion criteria have been satisfied. A participant begins treatment before laboratory confirmation because the investigator believes delaying therapy could affect recruitment goals.

According to GCP, what is the greatest concern?

A. Recruitment targets were prioritized over participant eligibility and protocol compliance.

B. Laboratory confirmation is optional if the investigator is experienced.

C. Participant reimbursement becomes invalid.

D. The sponsor automatically assumes responsibility for the deviation.

Correct Answer: A

Answer Explanation:
Participant eligibility criteria exist to protect safety and ensure scientifically valid study results. Initiating treatment before confirming eligibility represents a protocol deviation that may expose participants to unnecessary risk and compromise study integrity. GCP requires investigators to follow the approved protocol unless an immediate hazard requires emergency action, which is not the case here. Recruitment objectives should never influence eligibility decisions. The investigator remains responsible for protocol compliance, documenting deviations, assessing participant impact, and notifying the sponsor according to applicable procedures. Proper eligibility verification is fundamental to reliable clinical research.

Question 5.

Which document provides evidence that an Institutional Review Board (IRB) or Independent Ethics Committee (IEC) has approved a clinical study before enrollment begins?

A. Monitoring visit report

B. Ethics committee approval letter

C. Drug accountability log

D. Delegation of authority log

Correct Answer: B

Answer Explanation:
Before participant enrollment begins, GCP requires review and approval of the protocol, informed consent documents, recruitment materials, and other applicable study documents by an IRB or IEC. The approval letter serves as official evidence that ethical review has occurred and that participant rights, safety, and well-being have been considered. Sponsors and investigators must maintain this documentation within the Trial Master File and Investigator Site File. Monitoring reports, accountability records, and delegation logs are essential study documents but do not demonstrate ethical approval for study initiation.

Question 6.

A study participant reports mild dizziness during a scheduled visit. The investigator determines that the symptom is possibly related to the investigational product and resolves within one day without treatment.

How should this event generally be classified?

A. Serious adverse event

B. Adverse event

C. Protocol deviation

D. Monitoring finding

Correct Answer: B

Answer Explanation:
An adverse event (AE) is any untoward medical occurrence in a participant receiving a pharmaceutical product, regardless of whether a causal relationship exists. In this case, the dizziness is an adverse event because it occurred during trial participation and may be related to the investigational product. Since it did not result in hospitalization, death, disability, or another criterion defining seriousness, it would not generally qualify as a serious adverse event (SAE). Accurate documentation, assessment of severity and causality, and timely reporting according to the protocol are essential responsibilities under GCP.

Question 7.

A sponsor introduces a centralized electronic Trial Master File (eTMF). During an inspection, inspectors request documentation demonstrating who created, modified, and approved essential documents.

Which system feature is most important?

A. Automatic spell checking

B. Audit trail functionality

C. Color-coded document folders

D. Password expiration reminders

Correct Answer: B

Answer Explanation:
An audit trail is a critical component of validated electronic systems used in clinical research. It records who performed an action, what was changed, when the change occurred, and, when applicable, why it occurred. This supports transparency, accountability, and regulatory compliance. During inspections, auditors frequently review audit trails to verify document integrity and ensure records have not been improperly altered. Although other security features contribute to system management, only a robust audit trail provides the historical evidence necessary to demonstrate data reliability and compliance with Good Clinical Practice expectations.

Question 8.

During a multicenter study, one site repeatedly submits data well after protocol-defined timelines. Although the delayed entries are eventually accurate, database lock continues to be postponed.

What is the primary risk created by this situation?

A. Increased participant compensation

B. Reduced data quality oversight and delayed study completion

C. Automatic protocol termination

D. Ethics committee approval becomes invalid

Correct Answer: B

Answer Explanation:
Timely data entry allows sponsors and monitors to identify missing information, resolve discrepancies, detect safety signals, and maintain overall study quality. Consistent delays may postpone database cleaning, statistical analysis, regulatory submissions, and study completion. Although data accuracy remains important, delayed reporting reduces opportunities for timely monitoring and risk management. GCP emphasizes maintaining accurate, complete, and timely trial records throughout the study lifecycle. Delayed data entry alone does not invalidate ethics approval or automatically terminate a study, but it may require corrective actions to improve site performance.

Question 9.

A monitor discovers that investigational product inventory records show two missing medication kits. The site cannot immediately explain the discrepancy.

What should occur first?

A. Destroy all remaining investigational product.

B. Document the discrepancy and begin an investigation following sponsor procedures.

C. Replace the missing kits with unused medication from another site.

D. Ignore the discrepancy if participant safety has not been affected.

Correct Answer: B

Answer Explanation:
Investigational product accountability is a core GCP requirement. Every unit of study medication must be traceable from shipment through dispensing, return, or destruction. Missing medication requires immediate documentation and investigation to determine whether the discrepancy resulted from recording errors, dispensing mistakes, storage issues, or potential product loss. The sponsor and investigator should follow established procedures, reconcile inventory, and implement corrective actions if necessary. Borrowing medication from another site without authorization or ignoring accountability discrepancies undermines trial integrity and regulatory compliance.

Question 10.

A participant decides to withdraw consent for further study participation after six months but agrees to continue routine safety follow-up through medical record review.

According to GCP principles, what should the investigator do?

A. Continue collecting all study procedures without discussion.

B. Respect the participant’s decision and document the extent of consent withdrawal.

C. Delete all previously collected study data.

D. Replace the participant immediately with another subject.

Correct Answer: B

Answer Explanation:
Participants have the right to withdraw consent at any time without penalty or loss of entitled medical care. Withdrawal does not always mean that all study-related activities must stop if the participant voluntarily agrees to limited follow-up, such as safety monitoring or medical record review. Investigators should clearly document the participant’s wishes, explain any implications, and continue only those activities for which permission remains. Previously collected data generally remain part of the research dataset unless applicable regulations or consent terms require otherwise. Respect for participant autonomy is a fundamental ethical principle of GCP.

Question 11.

A clinical trial protocol requires laboratory specimens to be processed within 30 minutes of collection. At one study visit, a sample is processed after 75 minutes because of equipment failure.

How should this event generally be managed?

A. Record it as a protocol deviation, evaluate potential impact, and document corrective actions.

B. Discard the sample without documentation.

C. Repeat the laboratory value using estimated results.

D. Change the protocol after the visit to match actual practice.

Correct Answer: A

Answer Explanation:
Failure to follow protocol-defined laboratory handling requirements represents a protocol deviation. The investigator should document the incident, determine whether sample integrity or participant safety was affected, notify the sponsor as required, and implement corrective and preventive measures to reduce recurrence. Transparent documentation allows evaluation of the deviation’s effect on study endpoints and participant protection. Fabricating results, failing to document the event, or changing the protocol retrospectively would violate Good Clinical Practice and compromise scientific validity. Accurate reporting supports regulatory confidence in the study’s conduct.

Question 12.

A sponsor adopts a risk-based monitoring strategy instead of performing 100% on-site source data verification at every visit.

What is the primary objective of risk-based monitoring?

A. Eliminate all monitoring visits.

B. Focus monitoring resources on processes and data that are most critical to participant safety and trial quality.

C. Reduce regulatory requirements for investigators.

D. Replace all quality management activities.

Correct Answer: B

Answer Explanation:
Modern GCP encourages risk-based quality management by concentrating monitoring efforts on the aspects of a clinical trial that have the greatest potential impact on participant safety, rights, and data reliability. This approach may combine centralized monitoring, targeted on-site visits, statistical review, and risk assessments to identify emerging issues more efficiently than routine 100% verification. Risk-based monitoring does not eliminate oversight or reduce regulatory obligations. Instead, it enables sponsors to allocate resources effectively while maintaining compliance, improving quality management, and supporting reliable clinical trial outcomes.

Question 13.

A regulatory inspector asks an investigator how confidentiality of participant information is protected throughout the study.

Which response best reflects GCP expectations?

A. Participant names should appear in all sponsor reports.

B. Participants should be identified by coded identifiers whenever possible, with access to identifiable information limited to authorized individuals.

C. All participant records should be publicly available after study completion.

D. Confidentiality requirements end once the participant completes the trial.

Correct Answer: B

Answer Explanation:
Protecting participant confidentiality is a fundamental ethical and regulatory obligation. GCP requires investigators and sponsors to safeguard identifiable participant information by using coded subject identification numbers whenever practical and restricting access to authorized personnel such as monitors, auditors, inspectors, and regulatory authorities when appropriate. Confidentiality protections continue after study completion according to applicable regulations and record retention requirements. Public disclosure of identifiable participant information without authorization violates privacy principles and may breach legal requirements. Secure handling of research records maintains participant trust and regulatory compliance.

Question 14.

During a sponsor audit, an auditor finds several corrective actions from a previous audit that were never implemented by the site despite being formally accepted.

Which quality management principle has been most seriously compromised?

A. Continuous quality improvement

B. Participant recruitment

C. Randomization procedures

D. Product labeling

Correct Answer: A

Answer Explanation:
Corrective and preventive actions (CAPA) are essential components of an effective clinical quality management system. Identifying deficiencies is only the first step; organizations must implement, document, and verify corrective measures to prevent recurrence. Failure to complete agreed corrective actions indicates weaknesses in continuous quality improvement and may increase the likelihood of repeated protocol deviations, inspection findings, or participant safety concerns. Sponsors and investigators are expected to monitor CAPA effectiveness and maintain documentation demonstrating resolution. Continuous improvement is a central principle supporting high-quality, compliant clinical research.

Question 15.

A biotechnology company plans to submit trial results to multiple regulatory authorities. Before database lock, statisticians identify several unexplained data inconsistencies involving primary endpoint measurements across multiple study sites.

What is the most appropriate action before final analysis?

A. Lock the database to meet submission timelines.

B. Resolve data queries, investigate inconsistencies, and ensure the dataset accurately reflects verified source information before database lock.

C. Delete inconsistent participant records.

D. Average conflicting values across all sites.

Correct Answer: B

Answer Explanation:
Database lock should occur only after data management activities confirm that collected information is complete, accurate, and suitable for statistical analysis. Significant inconsistencies affecting primary endpoints require investigation through formal data queries, source verification when necessary, and documented resolution before analysis begins. Locking the database prematurely may compromise study conclusions and regulatory credibility. Deleting records or averaging conflicting values without investigation is scientifically unacceptable and inconsistent with GCP. Careful data cleaning ensures that trial results accurately represent participant outcomes and support reliable regulatory decision-making.
