A Therapeutic Confirmatory study primarily aims to do which?

• A. Demonstrate/confirm efficacy; establish safety; provide basis for benefit/risk; establish dose‑response
• B. Explore initial market launch
• C. Refine dosing in special populations
• D. Post-market safety evaluation

Answer: (A)

Therapeutic confirmatory studies are designed to provide robust evidence of a drug’s efficacy and safety in a large patient population to support regulatory approval and labeling. The goal is to demonstrate and confirm the therapeutic effect, establish a clear safety profile, and define the dose‑response relationship that guides real‑world dosing. This combination provides the basis for the benefit/risk assessment used in labeling and decision making for clinical use.

Other activities like preparing for a market launch or post‑marketing safety evaluation occur outside the primary aim of these confirmatory trials; refining dosing in special populations is typically addressed in other study types or later phases rather than the core purpose of a therapeutic confirmatory study.
