Progression Independent of Relapse Activity (PIRA) represents the gradual, sustained worsening of disability that occurs even without relapses. In this video, Dr. Barry Singer explains how PIRA is defined, why it affects many patients across the MS spectrum, and how clinicians can better detect subtle changes that reflect true long-term progression.
A simplified walkthrough of how 6‑month Confirmed Disability Progression (CDP) is measured in MS clinical trials. Dr. Barry Singer explains how EDSS changes are assessed, why sustained progression matters, and how this endpoint helps distinguish real, lasting disability worsening from temporary fluctuations.
Kaplan–Meier curves play a key role in visualizing how clinical events—such as confirmed disability progression—evolve over time in MS studies. In this video, Dr. Barry Singer provides a clear, simplified walkthrough of how these curves are constructed, how patient data contributes to each step, and what curve separation really tells us about treatment impact. This resource offers an accessible foundation for anyone looking to better understand KM interpretation in MS research.
