This chapter presents a 1995 commentary on the development of sequential designs for ‘continuous peeking’ in clinical trials, and the use of independent monitoring committees to conduct interim analysis of results. In recent years, such close oversight spawned its own set of problems — increasing pressure on trialists to stop enrolling patients when preliminary trends become apparent, before the study design call for termination of the trials.

Keywords: medical trials; clinical trials; monitoring; study design
