Collaborative Working Group on Clinical Trial Evaluations

Published: February 1, 1998

Article Abstract

Clinical trials support the efficacy and safety of new drugs on the market. They provide the UnitedStates Food and Drug Administration with the information needed to approve an Investigational NewDrug application and are the basis for package inserts provided by the manufacturers that guide cliniciansin the use of a new drug. Because clinical trials are vital to the effective and safe use of newdrugs, it is important to understand who participates in them, what questions are answered by clinicaltrials, and what questions are raised. The reader who asks the proper questions about issues such asmethodology, affiliations of the investigators, statistical analyses performed, location of study centers,and study populations will derive the most information from the report of a clinical trial.
