SOCRA - Society of Clinical Research Associates Society of Clinical Research Associates Source Documentation and Data 1 — Questions and Answers
Question 1: Which additional attributes extend the basic ALCOA principles to 'ALCOA+' in clinical research source documentation?
- Certified, Controlled, Encrypted, and Archived
- Complete, Consistent, Enduring, and Available (Correct answer)
- Authenticated, Chronological, Comprehensive, and Electronic
- Corrected, Centralized, Evaluated, and Approved
Correct answer: Complete, Consistent, Enduring, and Available
ALCOA+ expands on the foundational ALCOA framework by adding Complete, Consistent, Enduring, and Available — attributes that ensure data is not only accurate at the moment of recording but remains intact, coherent across records, and accessible throughout the study lifecycle.
Question 2: According to GCP guidelines, what is the correct way to correct an error in a paper source document?
- Apply correction fluid over the error, write the correct information above it, and initial the change
- Erase the error completely and write the correct information in the same space
- Draw a single line through the error, write the correction nearby, and add initials, date, and reason for change (Correct answer)
- Cross out the entire entry with multiple lines and rewrite the full entry on the next available line
Correct answer: Draw a single line through the error, write the correction nearby, and add initials, date, and reason for change
GCP requires that the original entry remain legible after any correction. A single line through the error, followed by the corrected value, the corrector's initials, the date, and the reason for the change preserves the audit trail and demonstrates transparency.
Question 3: How is a 'certified copy' of a source document defined under ICH E6 GCP?
- A document notarized by a legal authority confirming the investigator's signature is authentic
- A verified copy confirmed to be an exact reproduction of the original, preserving all content and context (Correct answer)
- A digital scan uploaded to a validated electronic document management system
- A photocopy reviewed and stamped by the principal investigator as accurate
Correct answer: A verified copy confirmed to be an exact reproduction of the original, preserving all content and context
A certified copy is any copy — paper, microfilm, or electronic — that has been verified to contain all the same information as the original, including data describing its context, content, and structure. Verification confirms the copy is a true and complete reproduction.
Question 4: Under 21 CFR Part 11, which requirement is essential for electronic source records to be considered trustworthy in a clinical trial?
- Electronic records must be printed to paper and countersigned by the PI within 48 hours
- A secure, computer-generated, time-stamped audit trail must capture all entries and changes to electronic records (Correct answer)
- All electronic source data must be reviewed and locked by the sponsor within 30 days of entry
- Electronic records must be backed up to offline physical media on a weekly schedule
Correct answer: A secure, computer-generated, time-stamped audit trail must capture all entries and changes to electronic records
21 CFR Part 11 mandates a secure, computer-generated, time-stamped audit trail that independently records operator actions — creation, modification, or deletion — without the ability to be altered. This ensures data integrity and supports regulatory inspection of the full data history.
Question 5: During Source Data Verification (SDV), what specific comparison does the CRA perform?
- Protocol eligibility criteria against the subject's signed informed consent form
- Data recorded in the Case Report Form against the original source documents at the investigative site (Correct answer)
- Adverse event narratives against published drug safety databases
- The site's standard operating procedures against current sponsor guidelines
Correct answer: Data recorded in the Case Report Form against the original source documents at the investigative site
SDV requires the CRA to compare data entered in the CRF directly against the original source documents to confirm that transcription was accurate, complete, and unaltered. This process is the primary mechanism for detecting data entry errors and unauthorized changes.
Question 6: According to ICH E6 GCP, what determines the minimum retention period for clinical trial source documents?
- At least 2 years after the last approval of a marketing application or 2 years after formal discontinuation of clinical development, whichever is later (Correct answer)
- Exactly 5 years from the date the last subject completed the trial
- 15 years from the date of regulatory submission in the primary market
- Indefinitely, until the investigator receives written authorization from the sponsor to destroy them
Correct answer: At least 2 years after the last approval of a marketing application or 2 years after formal discontinuation of clinical development, whichever is later
ICH E6 GCP requires source documents to be retained for a minimum of 2 years after the last marketing approval in an ICH region, or 2 years after formal discontinuation of clinical development — whichever comes later. Sponsors may contractually require longer retention periods beyond this minimum.
