How does Quorum define a single site vs. a central study?
Quorum defines a study as single site or central based upon with whom we communicate.
Single site: Quorum communicates directly with the site only. In this case, Quorum is not the central IRB for the study but the site has chosen Quorum as their IRB.
Central: Quorum communicates with the sponsor/CRO, protocol level decisions are made by the sponsor/CRO on behalf of site(s). In this case, Quorum is the designated central IRB for the study.
