IB: The Definition
- An Investigational Brochure (IB) is a document that provides essential information about an investigational drug to clinical trial investigators, regulatory authorities, and ethics committees.
- The Investigator’s Brochure (IB) is a compilation of the clinical and nonclinical data on the investigational product(s) that are relevant to the study of the product(s) in human subjects.
Purpose of IB
The purpose of IB is to:
- serves as a central repository of information about the investigational product, ensuring that clinical investigators have all the necessary data to conduct the trial safely and effectively.
- communicate the benefits and risks associated with the drug and to ensure that everyone involved in the clinical trial has the same understanding of the drug’s properties.
- provide the investigators and others involved in the trial with the information to facilitate their understanding of the rationale for, and their compliance with, many key features of the protocol, such as the dose, dose frequency/interval, methods of administration: and safety monitoring procedures.
Significance of IB
The significance of IB includes:
- Ensures Safety: Provides essential safety information to protect trial participants.
- Guides Investigators: Helps investigators understand the scientific rationale, potential risks, and therapeutic potential of the investigational product.
- Regulatory Compliance: Facilitates regulatory submissions and approvals by consolidating all relevant data in a single document.
- Training Tool: Acts as a reference for training clinical staff and ensuring consistency in trial conduct across multiple sites.
- Regulating the clinical trials
- To support Investigational Medicinal Product Dossier and Paediatric Investigation Plan submissions in Europe
Note: The ICH E6 guideline specifies that it should include information on the drug product to be investigated and its performance in non-clinical studies along with specific guidance to investigators on the drugs use.

Important Components of IB
The IB contains several important components, including:
Chemical and Physical Properties:
Information on the drug’s chemical and physical properties.
Mechanism of Action:
Description of the drug’s mechanism of action.
Pharmacokinetics and Pharmacodynamics:
Information on the drug’s pharmacokinetics and pharmacodynamics.
Safety Data:
Safety data from preclinical studies.
Proposed Clinical Trial:
Information on the proposed clinical trial, including the patient population to enroll and dosing regimens.
Potential Risks and Adverse Events:
Information on any potential risks or adverse events that may associated with the drug.
Key Takeaways
It is a critical document in clinical trials
Document should be more precise in defining the process
Investigator brochure acts as SOP in conducting trials and conducted trials for the investigators
In practice it should not exceed about 100 pages
It must sufficiently complete to communicate what an investigator needs to know about using the IMP
Conclusion
Considered a multidisciplinary document, the Investigator’s Brochure provides a summary of research work completed on an investigational medicinal product.
It serves several purposes and evolves as the development program progresses.
