Gnanasakthy A, Mordin M, Clark M, DeMuro C, Fehnel S, Copley-Merriman C. A review of patient-reported outcome labels in the United States: 2006 to 2010. Value Health. 2012 May;15(3):437-42.

OBJECTIVE: In 2004, Willke and colleagues reviewed the efficacy endpoints reported in the labels of new drugs approved in the United States from 1997 through 2002 to evaluate the use of patient-reported outcome (PRO) endpoints. Of the labels reviewed, 30% included PROs. Our study aimed to build on this work by describing the current state of PRO label claims granted for new molecular entities (and biologic license applications since February 2006 after the release of the US Food and Drug Administration (FDA) draft PRO guidance.

METHODS: All new molecular entities and biologic license applications approved by the FDA from January 2006 through December 2010 were identified by using the Web page of the FDA Drug Approval Reports. For all identified products, drug approval packages and approved product labels were reviewed to identify PRO endpoint status and to determine the number and type of PRO claims.

Of the 116 products identified, 28 (24%) were granted PRO claims; 24 (86%) were for symptoms, and, of these, 9 (38%) claims were pain related. Of the 28 products with PRO claims, a PRO was a primary endpoint for 20 (71%), all symptom related.

CONCLUSIONS: The FDA continues to approve PRO claims, with 24% of new molecular entities and biologic license applications being granted. Successful PRO label claims over the past 5 years have generally supported treatment benefit for symptoms specified as primary endpoints.
