More About Close Down

According to Good Clinical Practice, the close down of a clinical trial can only be done when both investigator/institution and sponsor files have been reviewed, and it has been confirmed that all necessary trial-related documentation have been completed. The proposed end date of a trial is determined by the study protocol; the protocol should also detail specific circumstances or events which may warrant an early termination date. At this stage all data queries should have been resolved, statistical analysis and interpretation of results completed, and reports written for funders, sponsors, relevant ethics committees and regulatory authorities. Documentation should be archived according to protocol and sponsor policy.
