Its purpose is to provide clear information like dose, dose regime, route of administration, known adverse events, and possible drug side effects. This information facilitates safety monitoring in the current study. It provides insight to support the clinical management of the study subjects during the course of the clinical trial. It informs the investigator about the risks and benefits of investigator product know till the day, so that during the study, if any challenge comes up, they can take guidance from IB.
