Potential Signals of Serious Risks/New Safety Information Identified from the Adverse Event Reporting System (AERS)

What is FDA posting?

The following reports list any potential signals of serious risks/new safety information that were identified using the AERS database during the indicated quarter. The appearance of a drug on this list does not mean that FDA has concluded that the drug has this listed risk. It means that FDA has identified a potential safety issue, but does not mean that FDA has identified a causal relationship between the drug and the listed risk. If after further evaluation the FDA determines that the drug is associated with the risk, it may take a variety of actions including requiring changes to the labeling of the drug, requiring development of a Risk Evaluation and Mitigation Strategy (REMS), or gathering additional data to better characterize the risk.
FDA wants to emphasize that the listing of a drug and a potential signal of a serious risk/new safety information on this Web site does not mean that FDA is suggesting that healthcare providers should not prescribe the drug or that patients taking the drug should stop taking the medication. Patients who have questions about their use of the identified drug should contact their health care provider.
FDA will complete its evaluation of each potential safety issue and may issue additional public communications as appropriate.

Why is FDA posting this information?

FDA is posting these reports in accordance with Title IX, Section 921 of the Food and Drug Administration Amendments Act of 2007 (FDAAA; see insert). FDA will publish a new list of potential signals of serious risks/new safety information identified each quarter.

Title IX, Section 921 of the Food and Drug Administration Amendments Act 2007 (FDAAA) (121 Stat. 962) amends the Federal Food, Drug and Cosmetic Act (FDCA) to add a new subsection (k)(5) to section 505 (21 U.S.C. 355).

This section in FDAAA, among other things, directs FDA to "conduct regular, bi-weekly screening of the Adverse Event Reporting System [AERS] database and post a quarterly report on the Adverse Event Reporting System Web site of any new safety information or potential signal of a serious risk identified by Adverse Event Reporting System within the last quarter." When a potential signal of a serious risk is identified from AERS data, it will be posted in the required report in the quarter in which it is first identified. A potential signal of a serious risk may in some cases constitute new safety information as defined in FDAAA (newly created section 505-1(b)(3) of the FDCA) which includes, among other things, information derived from adverse event reports about a serious risk associated with use of a drug that FDA has become aware of since the drug was approved or, for drugs that have REMS, since the REMS was required or last assessed. FDA will post each potential signal of a serious risk in the quarter in which it is first identified. If additional new safety information is developed concerning a potential signal that has already been posted, it will be addressed by FDA in new safety communications, but will not appear again as a new quarterly posting.

How was the list generated?

FDA staff in the Center for Drug Evaluation and Research (CDER) and Center for Biologics Evaluation and Research (CBER) regularly examine the AERS database as part of routine safety monitoring. When a potential signal of a serious risk is identified from AERS data, it is entered as a safety issue into CDER's Document Archiving, Reporting, and Regulatory Tracking System (DARRTS) or into CBER's Therapeutics and Blood Safety Branch Safety Signal Tracking (SST) system. Potential signals of serious risks are normally based upon groups of AERS reports, although a single AERS report could lead to further evaluation of a potential safety issue.

What information is provided?

The table in each report lists the names of products and potential safety issues that were entered into the above CDER or CBER tracking systems where the AERS database identified (or contributed to identification of) the potential safety issues. Additional information on each issue is also provided.

A new report will be made available each quarter showing newly identified potential signals of serious risks/new safety information identified from the AERS database during the previous quarter. Information from previous quarters will remain available with updates on the Web site.
