The Investigator’s Brochure (IB) and New Drug Application (NDA) MCQs With Answer
The Investigator’s Brochure (IB) and New Drug Application (NDA) are core documents in clinical development and regulatory approval that every B.Pharm student should master. The IB summarizes preclinical and clinical safety, pharmacology, toxicology, dosing rationale, and recommended monitoring for investigators. The NDA compiles clinical trial data, efficacy and safety analyses, chemistry, manufacturing and controls (CMC), and proposed labeling for regulatory submission. Understanding IB structure, data interpretation, CTD modules, risk–benefit assessment, investigator responsibilities, and regulatory expectations strengthens competency in clinical research and regulatory affairs. Now let’s test your knowledge with 30 MCQs on this topic.
