Clinical trial protocol development steps are vital for B. Pharm students to understand practical drug research. A well-constructed clinical trial protocol defines study objectives, study design, inclusion/exclusion criteria, endpoints, sample size calculation, randomization, blinding, safety monitoring, data management, and regulatory & ethics requirements. Familiarity with protocol components—such as Investigator’s Brochure, case report forms, informed consent, adverse event reporting, and statistical analysis plan—prepares students for roles in trial conduct, monitoring, and pharmacovigilance. Learning these steps improves trial quality, participant safety, and regulatory compliance. Now let’s test your knowledge with 30 MCQs on this topic.
