Notice of public workshop; request for comments.


The Food and Drug Administration (FDA) is announcing the following public workshop entitled “Non-Microbial Biomarkers of Infection for In Vitro Diagnostic Device Use.” The purpose of this workshop is to receive input from stakeholders and discuss approaches to the study of non-microbial biomarkers for differentiating viral from bacterial infections and for diagnosis and assessment of sepsis. Comments and suggestions generated through this workshop will facilitate further development of regulatory science for establishing appropriate comparator methods and clinically relevant performance standards for non-microbial based in vitro diagnostics for infection.


The public workshop will be held on October 16, 2015, from 8 a.m. to 5 p.m. Registration to attend the meeting must be made by 4 p.m. on October 6, 2015. Registration from those individuals interested in presenting comments should be received by September 16, 2015. See the SUPPLEMENTARY INFORMATION section for instructions on how to register for the meeting. Submit either electronic or written comments by 4 p.m. on November 13, 2015.


The public workshop will be held at the FDA White Oak Campus, 10903 New Hampshire Ave., Building 31 Conference Center, the Great Room (Rm. 1503), Silver Spring, MD 20993. Entrance for the public meeting participants (non-FDA employees) is through Building 1 where routine security check procedures will be performed. For parking and security information, please refer to​AboutFDA/​WorkingatFDA/​BuildingsandFacilities/​WhiteOakCampusInformation/​ucm241740.htm.

Submit electronic comments to Submit written comments to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville MD 20852. All comments should be identified with the docket number found in brackets in the heading of this document.

I. Background

There has been increasing interest in the development of non-microbiological biomarkers to aid in determining whether patient signs and symptoms consistent with infection are attributable to an infectious or non-infectious cause, Start Printed Page 34911and if infectious, whether of viral or bacterial etiology. Interest has ranged from aiding in the diagnosis of relatively mild outpatient upper respiratory symptoms to the assessment of critically ill patients. Progress in this area has been hindered by a lack of consensus on important issues in clinical trial design for new analytes; these issues include appropriate clinical trial designs (including acceptable comparator methods, e.g., for ascertaining viral or bacterial infections), clinical definitions of different disease states, and acceptable device performance (i.e., benefit/risk in different disease states and target populations). Devices that can differentiate a bacterial etiology from other causes of illness (e.g., viral, fungal, or non-infectious etiologies) can significantly impact antibiotic stewardship and potentially antimicrobial resistance.

II. Purpose and Scope of the Public Workshop

The purpose of the public workshop is to discuss the use of non-microbial biomarkers as indicators of infection, potential clinical trial designs that can be used to establish effectiveness, and benefit/risk considerations for use. Specifically, FDA seeks input from health care practitioners, industry, government, academia, and other stakeholders on these topics. This discussion is viewed as essential for establishing the appropriate methods to study the safety and effectiveness of these analytes for different possible uses.

This public workshop will consist of brief presentations providing information to frame the goals of the workshop and interactive discussions via several panel sessions. The presentations will focus on current and anticipated uses for non-microbial biomarkers of infection and a review of different approaches that have been considered for clinical trials. Following the presentations there will be a moderated discussion where participants and additional panelists will be asked to provide their individual perspectives. Topics to be discussed include: (1) Clinical uses for non-microbial biomarkers of infection, (2) comparator methods for studies differentiating viral from bacterial infection, (3) performance standards, (4) statistical methods appropriate for sepsis biomarker trials, and (5) unique considerations when studying pediatric populations.

In advance of the meeting, FDA will place a summary of the issues it believes need consideration on file in the public docket (docket number found in brackets in the heading of this document) and will post it at​MedicalDevices/​NewsEvents/​WorkshopsConferences/​default.htm. The deadline for submitting comments on this document for presentation at the public workshop is September 11, 2015, although comments related to this document can be submitted until November 13, 2015.

III. Attendance and Registration

Registration is free and available on a first-come, first-served basis. Persons interested in attending this public workshop must register online by 4 p.m. on October 6, 2015. 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 public workshop will be provided beginning at 7 a.m.

If you need special accommodations due to a disability, please contact Susan Monahan, Center for Devices and Radiological Health, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 66, Rm. 4321, Silver Spring, MD 20993-0002, 301-796-5661, email:, no later than 4 p.m. on October 2, 2015.

To register for the public workshop, please visit FDA's Medical Devices News & Events—Workshops & Conferences calendar at​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 Susan Monahan to register. Registrants will receive confirmation after they have been accepted. You will be notified if you are on a waiting list.

A. Streaming Webcast of the Public Workshop

This public workshop will also be Webcast. Persons interested in viewing the Webcast must register online by 4 p.m. on October 6, 2015. 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 October 8, 2015. If you have never attended a Connect Pro event before, test your connection at​common/​help/​en/​support/​meeting_​test.htm.
