What should be included in the Investigator’s Brochure (IB)?

The Investigator's Brochure (IB) plays a crucial role in providing essential information about an investigational drug to investigators and study staff involved in clinical trials. Option B is the correct choice because the IB should include a comprehensive summary of both clinical and non-clinical data. This data is vital as it informs investigators about the background, efficacy, safety, and mechanisms of the investigational product, thereby guiding them in the proper conduct of the clinical study.

Inclusion of both clinical and non-clinical data ensures that investigators are well-informed not only about the therapeutic effects observed in clinical trials but also about any preclinical data that can shed light on the drug's pharmacological properties, toxicology, and potential for adverse effects. This holistic view aids investigators in conducting informed discussions with participants and helps ensure the safety and ethical treatment of study subjects.

The other options, while they may seem relevant, do not cover the essential requirements of the IB. Including only clinical data would provide an incomplete picture and potentially overlook critical non-clinical findings that could impact study design or safety considerations. An overview of the research staff or financial agreements, although potentially useful in other contexts, are not standard requirements for the IB and do not contribute to the scientific understanding of the
