What type of clinical trial is typically conducted to test the efficacy of a new treatment compared to a placebo?

  1. Exploratory Trial

  2. Confirmatory Trial

  3. Pilot Trial

  4. Longitudinal Trial

The correct answer is: Confirmatory Trial

A confirmatory trial is designed specifically to test the effectiveness and safety of a new treatment compared to a placebo or existing treatments. These trials are typically larger in scale and follow rigorous methodologies to provide robust evidence that can confirm the findings of exploratory studies or pilot trials. The primary objective is to establish the treatment's efficacy in a statistically significant manner, ensuring that any observed effects are due to the treatment itself rather than chance. Confirmatory trials often adhere to predefined protocols and include randomization, blinding, and a control group to ensure that the results are reliable and valid. This type of trial is critical in the regulatory approval process, as it generates the necessary data to support claims regarding a treatment's effectiveness and safety in larger, more diverse populations. This is why understanding confirmatory trials is essential for professionals involved in clinical research, particularly when evaluating new interventions.
