Which statement best describes the broad aim of the development plan for a new drug?

• A. To maximize market potential.
• B. To minimize development time.
• C. To find a dose range and schedule where the drug can be shown to be safe and effective with an acceptable risk-benefit.
• D. To demonstrate superiority to all existing therapies.

Answer: (C)

The main idea is to establish a dosing plan that shows the drug can be safe and effective at an acceptable risk-benefit level. This means testing a range of doses and schedules to map how efficacy relates to safety, so a recommended dose can be identified for pivotal trials and regulatory submission. It’s about finding the right balance between benefit and risk, not just chasing market potential or rushing development.

Why the other ideas aren’t the broad aim: commercial goals like maximizing market potential aren’t about how the drug is developed scientifically; speeding up development can risk insufficient safety or efficacy data; and proving superiority to all existing therapies isn’t required or always feasible for every new drug. The development plan focuses on dose-ranging and safety-efficacy balance to support a favorable risk-benefit profile.
