SUMMARY:Setting sample size for common designs when evaluating interventio
 ns and biomarkers - Professor Toby Prevost\,  Kings College London

DESCRIPTION:Setting the sample size for health intervention trials typical
 ly requires interaction between statisticians and health professionals. In
  this talk I will bring together some of the methods for sample size calcu
 lation to show how the core formulae can help the statistician to improve 
 the inputs and outputs. The second part of the talk consists of an introdu
 ction to biomarkers and appropriate late phase designs for their evaluatio
 n\, with a worked example to set the sample size of a two-stage early-phas
 e biomarker study with local health professionals.\n\n
