Sub-investigator (Sub-I)

In Roles & organizations

A sub-investigator is a qualified member of the site team, usually a physician or other clinician, who performs trial-related medical duties under the principal investigator's supervision. Typical duties include assessing eligibility, examining participants, and judging whether an adverse event is related to the study treatment. Sub-investigators must be listed on the delegation log and, in some regions, on the regulatory investigator statement.
