Clinical trials need to better protect participants and research integrity as data accumulate

June 12, 2012

An Essay by Susan Ellenberg from the University of Pennsylvania describes alternative approaches to the evaluation of clinical trials, with the objectives both of preventing undue risks to participants and protecting the integrity of data.

Writing in this week's , the author outlines the importance of methods for ensuring independence of those involved in analysis of interim data, and for ensuring that early stopping guidelines are clearly laid out before a trial starts.

However, the author emphasises that issues around liability for individuals who provide these functions are currently unclear, and concludes: "DMCs [data monitoring committees] have become expected components of many , and provide an important oversight function".
