IB (Investigator’s Brochure) update

IB (Investigator’s Brochure) update contains

• Dose (of the study drug)
• Frequency of dosing interval
• Methods of administration
• Safety monitoring procedures

An IB contains a “Summary of Data and Guidance for the Investigator” section, of which the overall aim is to “provide the investigator with a clear understanding of the possible risks and adverse reactions, and of the specific tests, observations, and precautions that may be needed for a clinical trial. This understanding should be based on the available physical, chemical, pharmaceutical, pharmacological, toxicological, and clinical information on the investigational product(s). Guidance should also be provided to the clinical investigator on the recognition and treatment of possible overdose and adverse drug reactions that is based on previous human experience and on the pharmacology of the investigational product”.

The sponsor is responsible for keeping the information in the IB up-to-date. The IB should be reviewed annually and must be updated when any new and important information becomes available, such as when a drug has received marketing approval and can be prescribed for use commercially.
