Is a participant obliged to provide reasons for withdrawing prematurely?

The central idea here is participant autonomy and voluntary involvement. In good clinical practice, a participant may withdraw from a trial at any time for any reason, or for no reason at all, and investigators should not pressure them to provide an explanation. This protects the participant’s right to discontinue participation without penalty. When withdrawal occurs, the study team should acknowledge it, explain any practical implications for ongoing treatment or follow-up, and ensure that data already collected are handled according to the consent and protocol. The other options would undermine this autonomy by suggesting that a reason is required, that withdrawal depends on a signed consent form, or that withdrawal is only possible if the investigator asks.
