You should submit two copies total. One copy will include the information you claim to be confidential with a heading or cover note that states “THIS DOCUMENT CONTAINS CONFIDENTIAL INFORMATION”. The Agency will review this copy, including the claimed confidential information, in its consideration of comments. The second copy, which will have the claimed confidential information redacted/blacked out, will be available for public viewing and posted on http://www.regulations.gov. Submit both copies to the Division of Dockets Management. If you do not wish your name and contact information to be made publicly available, you can provide this information on the cover sheet and not in the body of your comments and you must identify this information as “confidential.” Any information marked as “confidential” will not be disclosed except in accordance with 21 CFR 10.20 and other applicable disclosure law. For more information about FDA's posting of comments to public dockets, see 80 FR 56469, September 18, 2015, or access the information at: http://www.fda.gov/​regulatoryinformation/​dockets/​default.htm.

Docket: For access to the docket to read background documents or the electronic and written/paper comments received, go to http://www.regulations.gov and insert the docket number, found in brackets in the heading of this document, into the “Search” box and follow the prompts and/or go to the Division of Dockets Management, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

I. Background

Innovations in liquid chromatography-mass spectrometry (LC/MS) technology have dramatically improved assay throughput and precision.^[1] FDA has cleared and approved several LC/MS- and MS-based devices as diagnostic tests, including assays for screening newborns for metabolic diseases, for identifying microbes from human cultures, and for measuring the concentrations of therapeutic drugs in blood. Currently, however, no LC/MS-based IVDs have been cleared or approved by FDA for measuring proteins and peptides. FDA would like to enhance engagement with the clinical LC/MS community concerning the development and validation of LC/MS-based devices and to work with the community toward developing guidelines for review that will be useful and relevant to both FDA and manufacturers. Prior to the workshop, FDA will place a discussion paper on file in the public docket (docket number found in brackets in the heading of this document) and will post it at http://www.fda.gov/​MedicalDevices/​NewsEvents/​WorkshopsConferences/​default.htm.

II. Topics for Discussion

This public workshop will consist of brief presentations providing information to frame the goals of the workshop, followed by interactive panel discussions. The presentations will focus on current and anticipated uses for LC/MS and discussions of different validation approaches. Following the presentations, a moderated discussion will ask speakers and additional panelists to provide their individual perspectives. Examples of topics for discussion surrounding the challenges to validation that are specific to LC/MS-based protein and peptide IVDs include:

• Identifying pre-analytical and analytical variables that impact precision and reproducibility;
• Defining methods of normalization, harmonization, and the use of internal standards for quantitation and device calibration;
• Developing quality control materials; and
• Identifying appropriate reference materials and predicate devices.

We are soliciting comments and feedback from the clinical LC/MS community regarding additional topics for FDA to consider. We anticipate that the comments and suggestions generated through this workshop will help facilitate the development of appropriate analytical and clinical validation methods for IVDs. The agenda of the workshop will include time for public comments. These comments can be submitted to the docket prior to the meeting (see ADDRESSES).
