The MM has the responsibility to review and evaluate information relevant to the product safety throughout the development and implementation of the protocol. The MM will be responsible for providing safety oversight and reviewing the protocol (e.g., study halting rules) and information about the study product as it becomes available, such as the Investigational Brochure (IB), other DMID trials, and reported safety events. The DMID MM, in consultation with the protocol team and safety oversight committees, will provide safety review during the execution of the clinical trial. This oversight includes reviewing safety information and providing applicable recommendations. The DMID MM provides recommendations, as appropriate, to members of the study team, which may include, but is not limited to: DMID, the funder, manufacturer, and IND holder.
