SUPPLEMENTARY INFORMATION: I. Background In accordance with sections 515(d)(4) and (e)(2) of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 360e(d)(4) and (e)(2)), notification of an order approving, denying, or withdrawing approval of a PMA will continue to include a notice of opportunity to request review of the order under section 515(g) of the FD&C Act. The 30-day period for requesting reconsideration of an FDA action under § 10.33(b) (21 CFR 10.33(b)) for notices announcing approval of a PMA begins on the day the notice is placed on the Internet. Section 10.33(b) provides that FDA may, for good cause, extend this 30-day period. Reconsideration of a denial or withdrawal of approval of a PMA may be sought only by the applicant; in these cases, the 30-day period will begin when the applicant is notified by FDA in writing of its decision. The regulations provide that FDA publish a quarterly list of available safety and effectiveness summaries of PMA approvals and denials that were announced during that quarter. The following is a list of approved PMAs for which summaries of safety and effectiveness were placed on the Internet from July 1, 2013, through September 30, 2013. There were no denial actions during this period. The list provides the manufacturer’s name, the product’s generic name or the trade name, and the approval date.

(Select this public workshop from the posted events list.) SUPPLEMENTARY INFORMATION: I. Background Thrombosis, or blood clot formation, is a major complication in the use of blood-contacting medical devices. Thrombosis often leads to device malfunction and severe adverse events such as stroke or myocardial infarction. To improve device quality and reduce the occurrence of thrombus formation, it is important to fully assess the thrombogenic potential of a medical device prior to clinical use and make material or geometrical modifications if necessary. The current thrombogenicity test paradigm relies heavily on animal studies. For implanted devices, where animal studies are often conducted to assess safety and possible effectiveness, thrombogenicity endpoints can also be included. However, for many interventional devices, where other animal studies are not commonly requested, FDA has traditionally recommended a 4-hour in vivo canine thrombogenicity test model for assessment of thrombogenic potential. Because there have been questions about the consistency, reliability, and clinical relevance of this 4-hour canine thrombogenicity model, FDA is interested in optimizing the conduct of this in vivo test and/or identifying alternative in vitro tests that provide equivalent or improved clinical insight into the potential for thrombogenicity of medical devices while minimizing expenses and animal use, if possible. This workshop will bring together academia, industry professionals, and FDA regulators to discuss the advantages, limitations, and optimization of both in vivo and in vitro thrombogenicity test methods, and identify alternative in vitro tests that show promising clinical relevance. We will discuss testing methods related to a broad range of blood contacting devices, especially for cardiovascular applications. Ideas generated during this workshop may facilitate development of new guidance and/or standards for thrombogenicity testing that optimize current in vivo methods and/or utilize in vitro methods. II. Topics for Discussion at the Public Workshop FDA seeks to address and receive comments on the following topics: 1. Strengths, weaknesses, and optimization of in vivo thrombogenicity test methods; 2. Current methodologies for conducting in vitro thrombogenicity PO 00000 Frm 00079 Fmt 4703 Sfmt 4703 14055 testing (e.g., blood conditions, static versus dynamic methods, and different test endpoints); 3.
