Notice of public workshop; request for comments.
The Food and Drug Administration (FDA) is announcing the following public workshop entitled “ASTM International-FDA Workshop on Absorbable Medical Devices: Lessons Learned From Correlations of Bench Testing and Clinical Performance.” FDA is co-sponsoring the workshop together with ASTM International, an organization responsible for the development and delivery of international voluntary consensus standards for engineered products, including medical devices. The purpose of this public workshop is to provide a forum for highlighting and discussing the use of absorbable materials in medical devices across a broad range of indications with the aim of defining successful and unsuccessful methods to predict clinical performance. The main topics to be discussed include identification of test methods for establishing correlations between in vitro and in vivo degradation of absorbable implant devices, and the interaction of mechanical loading and mechanical performance with degradation. While there will be an emphasis on cardiovascular indications as part of a panel session, characterization techniques and experiences from both cardiovascular as well as non-cardiovascular devices will be discussed and are encouraged.
Date and Time: The public workshop will be held on November 28, 2012, from 8:30 a.m. to 5 p.m. EST.
Location: The public workshop will be held at the FDA's White Oak Campus, 10903 New Hampshire Ave., Bldg. 31 Conference Center, the Great Room (rm. 1503), Silver Spring, MD, 20993-0002. Entrance for the public workshop participants (non-FDA employees) is through Building 1 where routine security check procedures will be performed. For parking and security information, please refer to http://www.fda.gov/AboutFDA/WorkingatFDA/BuildingsandFacilities/WhiteOakCampusInformation/ucm241740.htm.

Registration: Registration is free and available on a first-come, first-served basis. Persons interested in attending this public workshop must register online by November 13, 2012. Early registration is recommended because facilities are limited and, therefore, FDA may limit the number of participants from each organization. If time and space permits, onsite registration on the day of the workshop will be provided beginning at 8 a.m.

To register for the public workshop, please visit FDA's Medical Devices News & Events—Workshops & Conferences calendar at http://www.fda.gov/MedicalDevices/NewsEvents/WorkshopsConferences/default.htm. (Select this public workshop from the posted events list.) Please provide complete contact information for each attendee, including name, title, affiliation, address, email, and telephone number. Those without Internet access should contact Maureen Dreher or Erica Takai to register (see Contact Person). Registrants will receive confirmation after they have been accepted. You will be notified if you are on a waiting list.
Streaming Webcast of the Public Workshop: This public workshop will also be Webcast. Persons interested in viewing the Webcast must register online by November 13, 2012, 5 p.m. EST. Early registration is recommended because Webcast connections are limited. Organizations are requested to register all participants, but to view using one connection per location. Webcast participants will be sent technical system requirements after registration and will be sent connection access information after November 23, 2012.

Requests for Oral Presentations: This public workshop includes presentations in topic-focused sessions. If you wish to present at the workshop, please submit an abstract at: http://www.astm.org/f04wkshp1112.htm.
FDA has included general topics in this document. Following the close of the call for abstracts, FDA and ASTM International members of the workshop organizing committee will determine the amount of time allotted to each presenter, the approximate time each oral presentation is to begin, and will select and notify participants by October 1, 2012. All requests to make oral presentations must be received by the close of the call for abstracts on September 1, 2012. If selected for presentation, any presentation materials must be emailed to Maureen Dreher (see Contact Person) no later than November 23, 2012. No commercial or promotional material will be permitted to be presented or distributed at the public workshop.
Comments: FDA is holding this public workshop through co-sponsorship with ASTM International to obtain information on test methods for establishing correlations between in vitro and in vivo degradation of absorbable devices. In order to permit the widest possible opportunity to obtain public comment, FDA is soliciting either electronic or written comments on all aspects of the public workshop topics. The deadline for submitting comments related to this public workshop is December 28, 2012.

Recent studies have identified promising results for the use of absorbable materials in implantable devices for endovascular therapies such as fully absorbable cardiovascular stents where the stent platform degrades, in addition to absorbable coatings. The use of these materials for cardiovascular indications, however, poses new risks due to the critical fatigue and mechanical loading demands that the implant must withstand and perform. Moreover, the optimal preclinical/bench testing paradigm to predict clinical performance of fully absorbable cardiovascular devices is not yet defined.
This public workshop will discuss the use of absorbable materials (including synthetic polymers as well as erodible metals) in medical devices across a broad range of indications with the aim of defining successful and unsuccessful methods to predict clinical performance, and will subsequently apply lessons learned to unique challenges for cardiovascular indications. Therefore, we invite presenters to share their experience with respect to cardiovascular and non-cardiovascular medical devices, both those that are fully absorbable and those with only a component or coating that is absorbable.
This public workshop will bring together the expertise of academia and industry professionals to define test methods as well as to educate and inform industry, academia, and device regulators on the performance and predictability of absorbable medical device degradation. Workshop participants will seek to define the critical factors for preclinical/bench testing and clinical predictability. They will then apply lessons learned from marketed devices for non-cardiovascular indications to the emerging uses of absorbable devices to treat cardiovascular disease.
II. Topics for Discussion at the Public Workshop
Topics to be discussed at the public workshop include, but are not limited to:
- Correlations of in vitro and in vivo absorption
- Quantitative characterization of absorption kinetics
- Test methods to identify interactions of absorption with mechanical loading
- Test methods to assess mechanical performance of the absorbable product
The lessons learned from both early cardiovascular and well-established non-cardiovascular device experiences will be presented. These lessons will be discussed in the context of emerging cardiovascular uses of absorbable materials as part of a panel session at the end of the workshop.
