before deciding to participate.
12. What is an Informed Consent Form (ICF)?
ICF is a written document containing all relevant information about the study and signed by the participant before any study procedure.
13. Can a Participant Withdraw from a Trial?
Yes.
Participants can withdraw from a study at any time without any penalty or loss of medical benefits.
14. What is Vulnerable Population?
Groups requiring additional protection:
- Children
- Pregnant women
- Prisoners
- Economically disadvantaged individuals
15. What is an Ethics Committee?
An Ethics Committee (IEC/IRB) reviews, approves, and monitors clinical trials to ensure participant rights and safety.
Safety Reporting Questions
16. What is an Adverse Event (AE)?
Any unfavorable medical occurrence in a participant during a clinical trial.
It may or may not be related to the study drug.
17. What is a Serious Adverse Event (SAE)?
Events that:
- Cause death
- Are life-threatening
- Require hospitalization
- Cause disability
- Result in congenital anomaly
18. What is SUSAR?
Suspected Unexpected Serious Adverse Reaction.
A serious adverse reaction not consistent with existing safety information.
19. What is Pharmacovigilance?
Science related to:
- Detection
- Assessment
- Understanding
- Prevention
of adverse drug reactions.
20. Why is Safety Reporting Important?
Safety reporting helps identify risks and protects participants throughout the study.
Protocol Related Questions
21. What is a Protocol?
A protocol is a written document describing how a clinical trial will be conducted.
