Ensures Scientific Validity
The Core Principle
A feasibility study is the first line of defense for a trial's scientific integrity. It rigorously vets whether the research question is answerable with the proposed protocol, patient population, and methodology.
Why It's Critical
This process confirms that the trial's scientific goals are not just theoretical but practically achievable, preventing the launch of studies that are doomed from the start. It's about ensuring the science can be executed in the real world.
Real-World Impact
A trial for a new oncology drug is designed with a primary endpoint that requires a specific, rare biomarker. Feasibility analysis reveals that only 1 in 10,000 people have this marker, making recruitment impossible. The study is redesigned to use a more common secondary biomarker, saving it from immediate failure.
