Example text

In confirmatory trials, the patients chosen are a homogeneous group, which helps increase the statistical power. The inclusion and exclusion criteria clearly define the target population to be enrolled, and it is not advisable to change the criteria during the study. This is because the more homogeneous the population is, the less variability, and the greater the power of the study to detect a difference in response, at least using traditional statistical methods. Also, in a confirmatory study, observation is focused on the primary endpoint.

First, the information from the learning period is very important because it allows proper design of the confirmatory study. Collecting and characterizing as much information as possible about the dose response, toxicity curve, subgroups’ difference in response and adverse events, PK/PD characteristics, and other factors all improve the likelihood of success in the confirmatory studies if the information is utilized effectively. And, as he rightly points out, clinicians who will be using the drug also often need that information.

They are cautiously optimistic about the use of adaptive designs in pivotal clinical studies designed to result in approval of a drug. 13 Regulatory Guidance from the FDA The FDA has issued some specific guidance on how the sponsor should interact with the FDA with regard to adaptive clinical trials during the planning, conduct, and reporting of the study, as outlined in the excerpt below from (FDA 2010). The purpose and nature of the interactions between a study sponsor and FDA varies with the study’s location (stage) within the drug development program.
