Investigator-initiated trial (IIT)

    In Roles & organizations

    Also known as: investigator-sponsored study, ISS

    An investigator-initiated trial is a study designed and run by a clinician or academic group rather than by a company. A company may still provide funding or the study drug, but it does not act as sponsor. These trials often answer practical questions that commercial trials do not, such as how two existing treatments compare.
