Informed Consent is defined as

• A. The process by which a subject voluntarily confirms his or her willingness to participate in a particular trial, after having been informed of all aspects relevant to the subject's decision to participate--documented by means of a written, signed and dated informed consent form
• B. A form that is used to collect patient's blood samples
• C. The act of reviewing trial data by the sponsor
• D. The official review by the regulatory authority

Answer: (A)

Informed consent is a process that ensures a participant’s voluntary willingness to join a trial after being informed of all aspects relevant to their decision. This means the subject understands the purpose, risks, benefits, procedures, and alternatives, and has the opportunity to ask questions before agreeing. The agreement is then documented with a written, signed, and dated informed consent form, establishing that the participant consented freely and understands their participation. This concept emphasizes autonomy and protects the participant’s rights and welfare, and it is distinct from using a form merely to collect data, from sponsor data review, or from regulatory authority approvals.
