Historical Borrowing in Clinical Trials

Presented by Dr. Scott Berry, Berry Consultants

Clinical trials never occur in a vacuum. Historical data such as previous randomized trials, observational data, or real-world evidence is ubiquitous. Incorporating this information into a clinical trial has the potential to decrease sample size and/or improve decision accuracy, but only if the external evidence is similar to the current trial. When this similarity is absent, external borrowing can result in large biases, decreased power, or inflated type I error depending on the discrepancy. In this webinar we will discuss how to quantify the pros and cons of borrowing, how to quantify the “sweet spot” under which historical borrowing is beneficial and discuss the factors that might make historical data likely to fulfill those conditions. This information allows investigators to assess whether historical borrowing is promising for their own trials.
