Abstract:
|
In this presentation, we focus on typical tools and techniques used for performing blinded data reviews from multiple perspectives in ongoing clinical trials. We cover application areas ranging from blinded statistical analysis to event milestones and timeline predictions. The iterative techniques include estimation of parameters for various distributional assumptions, simulation techniques for event prediction, and re-calibration of parameters to incorporate external inputs. We also briefly discuss the extensive validation techniques to detect model specification and data quality issues in time-to-event predictions. We illustrate the application of techniques using a standard commercial software product and relevant R packages. The illustrative examples are based on our practical experience in performing similar blinded data reviews in ongoing clinical trials.
