Group sequential designs can help clinical trial teams make earlier decisions on efficacy or futility—but their success depends on having the right data available at the right time.

In this episode, IDDI and Marvin EDC experts take a closer look at the methodology and technology behind group sequential designs. From interim analysis timing and spending functions to continuous data checks and real-time reporting, they explore what it takes to support reliable decisions during an ongoing trial. Discover why aligning statistical planning, EDC configuration and data-cut workflows from the start is essential for a smooth and efficient interim analysis.
