Which statement about post-marketing trials is correct?

• A. They are required before approval
• B. They collect post-approval safety and effectiveness data
• C. They only study marketing strategies
• D. They replace Phase III trials

Answer: (B)

Post-marketing trials are conducted after a product is approved to collect safety and effectiveness data in real-world use over longer periods. This makes the statement that they gather post-approval safety and effectiveness data the correct one. They are not required before approval, they do not focus on marketing strategies, and they do not replace Phase III trials; they occur after approval to expand safety and effectiveness understanding in broader patient populations.
