CTA Protocol Development & Review 2 — Questions and Answers
Question 1: Which section of a clinical trial protocol defines the statistical methods for analyzing primary and secondary endpoints?
- Inclusion/Exclusion Criteria
- Statistical Analysis Plan (Correct answer)
- Study Objectives
- Risk Management Plan
Correct answer: Statistical Analysis Plan
The Statistical Analysis Plan (SAP) section of the protocol defines the methods for analyzing primary and secondary endpoints.
Question 2: When a protocol amendment significantly changes the risk-benefit profile of a study, what is the FIRST required action?
- Notify the sponsor's legal department
- Submit the amendment to the IRB/IEC for review and approval (Correct answer)
- Update the informed consent form after patients are enrolled
- Implement the change and notify the IRB within 30 days
Correct answer: Submit the amendment to the IRB/IEC for review and approval
Significant protocol amendments that affect risk-benefit must be submitted to the IRB/IEC for review and approval before implementation.
Question 3: What is the purpose of a protocol deviation log in clinical trial management?
- To document sponsor communications
- To track and report all instances where the protocol was not followed (Correct answer)
- To record adverse events only
- To store investigator credentials
Correct answer: To track and report all instances where the protocol was not followed
A protocol deviation log systematically tracks all instances where the study was not conducted per the approved protocol.
Question 4: Under ICH E6(R2), which element is NOT typically required in the protocol background and rationale section?
- Summary of preclinical and clinical findings
- Description of the disease or condition being studied
- Detailed manufacturing process for the investigational product (Correct answer)
- Justification for the proposed study design
Correct answer: Detailed manufacturing process for the investigational product
The detailed manufacturing process belongs in the Investigator's Brochure, not in the protocol's background and rationale section.
Question 5: A protocol specifies a 7-day visit window for a study assessment. A subject's scheduled Day 30 visit occurs on Day 38. How should this be classified?
- Protocol deviation (Correct answer)
- Protocol violation
- Adverse event
- Acceptable per protocol
Correct answer: Protocol deviation
Missing the allowed visit window constitutes a protocol deviation that must be documented.
Question 6: Which ICH guideline specifically addresses the structure and content of clinical study protocols?
- ICH E3
- ICH E8 (Correct answer)
- ICH E6(R2)
- ICH E9
Correct answer: ICH E8
ICH E8 provides guidance on the general considerations for clinical trials including the structure and content of protocols.
Question 7: What does a 'protocol synopsis' typically contain?
- Full statistical analysis details
- A brief summary of key protocol elements including objectives, design, and endpoints (Correct answer)
- Complete adverse event reporting procedures
- All protocol appendices and attachments
Correct answer: A brief summary of key protocol elements including objectives, design, and endpoints
A protocol synopsis is a condensed summary of the key elements of the full protocol including objectives, design, population, and endpoints.
