Comment	Impartial witness requirement for subjects unable to read

Text

2.8.9 If a participant or the legally acceptable representative is unable to read, an impartial witness should be present (remotely or in-person) during the entire informed consent discussion. After the informed consent form and any other information is read and explained to the participant or the participant’s legally acceptable representative and they have orally consented to the participant’s trial participation and, if capable of doing so, have signed and dated the informed consent form, the witness should sign and date the consent form. By signing the consent form, the witness attests that the consent information was accurately explained to and apparently understood by the participant or the participant’s legally acceptable representative and that informed consent was freely given by the participant or the participant’s legally acceptable representative.
