Enrichment Strategies for Clinical Trials To Support Demonstration of Effectiveness of Human Drugs and Biological Products; Guidance for Industry; Availability

摘要

The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry entitled "Enrichment Strategies for Clinical Trials to Support Demonstration of Effectiveness of Human Drugs and Biological Products." The purpose of this guidance is to assist industry in developing enrichment strategies that can be used in clinical investigations intended to demonstrate effectiveness (and in some cases safety) of human drugs and biological products. This guidance defines several types of enrichment strategies, provides examples of potential clinical trial designs, and discusses potential regulatory considerations when using enrichment strategies in clinical trials. This guidance finalizes the draft guidance entitled "Enrichment Strategies for Clinical Trials to Support Approval of Human Drugs and Biological Products" issued on December 17, 2012.
