Data Monitoring Committee Section

SPIRIT 2025 explanation guidance calls for protocols to state whether a data monitoring committee is planned and, if so, describe its composition, role, reporting structure, independence, conflicts, and where charter details can be found. Many trials do not require a formal DMC. Explain the applicable arrangement rather than implying that every trial must have one.

Quick answer

A Data Monitoring Committee section explains whether a DMC is used and, when it is, who it comprises, what it reviews, how independent it is, and how it reports recommendations.
