Speaker: Ram Tiwari, CDRH, FDA
Bill Wang


In this keynote, I will present some innovative Frequentist/Bayesian statistical methods that supports the CDRH mission for development of first of its kind in the world, safe, and effective medical devices. These methods include: i) leveraging information from a real-world data (RWD) source to construct or augment the control arm or a single-arm in an investigational clinical study, ii) benefit-risk assessment for a therapeutic or a diagnostics device, iii) likelihood-ratio-test (LRT) based signal detection methods for large safety databases, and iv) a site-selection tool for inspection.
