Section outline

  • Lecture 6: Non-Inferiority Trials
    Faculty:  Vinay Prasad

    Non inferiority trials are studies that seek to show a new treatment, compared to an established treatment, is no worse than by some amount. That amount is called the margin or delta.  Equivalence trials are subset of the non-inferiority design

    • Live Large Group Session (Access restricted to registered students): Thursday, 8:45am - 10:15am PT.  Brief formal review of lecture followed by question and answer discussion. Recorded lecture should be viewed prior to this session.

      Workshop 4: In this zoom/live session, Dr. Prasad will lead a discussion about the pitfalls of non-inferiority. Who defines the delta?  What happens if the older treatment is delivered sub-optimally?  Can a trial be non-inferior, but actually worse?  And, finally, what percentage of NI trials are non-inferior?
