✍️ Sample CPI Questions & Answers

1. Which action by a CPI constitutes research fraud under federal regulations?
✓ Intentionally falsifying source documents to match case report forms

Falsifying source documents is research fraud, violating FDA regulations, GCP, and professional ethical standards.

2. An investigational drug shows non-linear (saturable) pharmacokinetics at therapeutic doses. What is the most important clinical implication for the trial?
✓ Small dose increases may cause disproportionately large increases in drug exposure

Saturable (Michaelis-Menten) kinetics cause non-proportional AUC increases with dose escalation, meaning small dose increments can lead to marked toxicity in dose-finding studies.

3. How long must drug accountability records typically be retained after study completion under FDA regulations?
✓ 2 years after the study is approved or discontinued, or 2 years after the investigational drug is marketed

Under 21 CFR 312.62, investigators must retain records for 2 years after a marketing application is approved or, if no application is filed, 2 years after the investigation is discontinued and FDA is notified.

4. In the context of CPI responsibilities, what does the term 'sponsor-investigator' mean?
✓ An individual who both initiates and conducts a clinical investigation

A sponsor-investigator is an individual who both initiates and conducts a clinical investigation and assumes all sponsor and investigator responsibilities.

5. When a protocol specifies 'washout period' requirements before study drug initiation, the primary purpose is to:
✓ Eliminate prior treatment effects that could confound study results or cause interactions

Washout periods eliminate residual effects of prior treatments to reduce confounding and prevent drug-drug interactions.

6. What is a data management plan in clinical research?
✓ A plan for data collection, storage, and analysis

A data management plan (DMP) is essential in clinical research for systematically organizing and handling all data generated during a study. It outlines procedures for data collection, entry, storage, quality control, security, and eventual analysis, ensuring data integrity, accessibility, and compliance with regulatory requirements.
