Consented But Not Treated (CNT) refers to participants who sign informed consent but do not receive the investigational intervention.
CNT status may occur due to screening failures, eligibility changes, withdrawal, or protocol-defined discontinuation before dosing. Tracking CNT participants is important for recruitment metrics and transparent trial reporting. Proper documentation ensures participant data are handled appropriately and consent decisions are respected. CNT reporting also supports oversight of enrollment processes and protocol feasibility.
