Which regulatory document must be reviewed and signed by each participant before enrolling in a clinical trial?
Answer: Informed consent form
The informed consent form must be reviewed, understood, and signed by each participant before enrollment to protect patient autonomy.
What is the primary purpose of a placebo control group in a clinical trial?
Answer: To provide a baseline for comparing the investigational drug's effects
A placebo control group provides a baseline comparator so researchers can isolate the true pharmacological effect of the investigational drug.
What does the term 'double-blind' mean in the context of a clinical trial?
Answer: Neither the participant nor the investigator knows who receives active drug or placebo
Double-blind means both the participant and the investigator are unaware of treatment assignments, reducing bias in assessment and reporting.
In clinical trial terminology, what is an 'endpoint'?
Answer: A measurable outcome used to evaluate the drug's effect
An endpoint is a predefined, measurable outcome such as tumor reduction or blood pressure change used to evaluate whether the drug achieves its intended effect.
Which type of clinical trial design randomly assigns participants to treatment groups?
Answer: Randomized controlled trial
A randomized controlled trial (RCT) uses random assignment to treatment groups, minimizing selection bias and allowing causal conclusions.
What is the role of a Data Safety Monitoring Board (DSMB) in a clinical trial?
Answer: To independently review accumulating data and recommend trial continuation or stoppage
A DSMB independently reviews unblinded accumulating safety and efficacy data and recommends whether a trial should continue, be modified, or be stopped.
Which document provides investigators with comprehensive information about an investigational drug's preclinical and clinical data?
Answer: Investigator brochure
The investigator brochure compiles all preclinical and clinical data about the investigational drug to help investigators understand its risks and rational use.
