Questions and Answers
What is the primary role of an impartial witness in the informed consent process?
An impartial witness ensures that the informed consent process is fair by being independent and reading the consent form to those who cannot.
How do Independent Ethics Committees (IECs) contribute to the protection of human subjects in clinical trials?
IECs review and approve trial protocols and ensure the rights, safety, and well-being of human subjects are safeguarded.
What distinguishes the process of informed consent from mere consent in clinical trials?
Informed consent involves providing potential participants with all relevant information about the trial, ensuring they voluntarily confirm their willingness to participate.
Can the composition and operation of Independent Ethics Committees vary across different countries, and if so, why?

Study Notes
Adverse Drug Reaction
- Refers to noxious and unintended responses to a drug occurring at standard therapeutic doses.
Approved Drugs
- Must receive approval from the FDA in the U.S. before marketing.
- The approval process includes pre-clinical studies, clinical trials, and New Drug Application submission.
Approval (Institutional Review Boards)
- Affirmative decision from IRB to conduct a clinical trial at an institution, adhering to Good Clinical Practice (GCP).
Audit
- A systematic examination of trial-related activities and documents to ensure compliance with the protocol and regulations.
Audit Certificate
- A formal declaration by the auditor confirming that an audit has taken place.
Audit Report
- A written evaluation of audit results prepared by the sponsor's auditor.
Audit Trail
- Documentation that facilitates the reconstruction of the sequence of events in a clinical trial.
Blinding/Masking
- Keeping one or more parties unaware of the treatment assignments to reduce bias.
- Single-blinding involves subjects being unaware, while double-blinding includes subjects and investigators.
Impartial Witness
- An independent person who assists in the informed consent process for subjects who cannot read, ensuring unbiased involvement.
Independent Ethics Committee (IEC)
- An independent review board responsible for protecting the rights and safety of human subjects in trials.
Informed Consent
- A voluntary agreement by a subject to participate in a trial, documented by a signed consent form after thorough information disclosure.
Investigator's Brochure
- A compilation of clinical and nonclinical information relevant to the investigational product(s) being studied.
Legally Acceptable Representative
- An individual authorized by law to provide consent on behalf of a prospective trial subject.
Monitoring
- Oversight of a clinical trial's progress to ensure compliance with protocols and regulatory requirements.
Monitoring Report
- A report generated after site visits or communication, detailing observations and compliance issues.
Multicentre Trial
- Clinical trials conducted under a single protocol at multiple sites with various investigators.
Nonclinical Study
- Biomedical studies that do not involve human subjects.
Protocol
- A document detailing the objectives, design, methodology, and statistical considerations for a clinical trial.
Protocol Amendment
- Written changes or clarifications to an existing protocol.
Quality Assurance (QA)
- Planned actions to ensure data and trial conduct comply with GCP and regulatory standards.
Quality Control (QC)
- Techniques used within the QA system to verify compliance with quality requirements.
Randomization
- Assignment of trial subjects to treatment groups using chance methods to minimize bias.
Regulatory Authorities
- Governing bodies with the power to regulate clinical trials and review submitted data.
Serious Adverse Event (SAE) or Serious Adverse Drug Reaction (Serious ADR)

Source Data
- Original records necessary for evaluating a clinical trial's findings.
Source Documents
- Original documents, data, and records relevant to clinical trial activities including hospital records and lab notes.
Vulnerable Subjects
