Notice of public workshop; request for comments.


The Food and Drug Administration (FDA, the Agency, or we) is announcing the following public workshop entitled “Cardiac Troponin Assays.” The purpose of the workshop is to discuss the development of innovative troponin assays designed to aid in the diagnosis of myocardial infarction (MI) and additional clinical uses of these assays. The workshop is intended to enhance engagement with stakeholders to facilitate device development and to discuss scientific and regulatory challenges associated with the analytical and clinical validation methods for troponin assay devices. Public input and feedback gained through this workshop may aid in the development of science-based approaches to aid in the efficient development of innovative, safe and effective, troponin diagnostic assays, which may lead to better patient care.


The public workshop will be held on November 28, 2017, from 8:30 a.m. to 5 p.m. Submit either electronic or written comments on this public workshop by November 27, 2017. See the SUPPLEMENTARY INFORMATION section for registration date and information.


The public workshop will be held at FDA's White Oak Campus, 10903 New Hampshire Ave., Bldg. 31, Rm. 1503 (The Great Room), Silver Spring, MD 20993. Entrance for the public workshop participants (non-FDA employees) is through Building 1 where routine security check procedures will be performed.

I. Background

Since first discovered, cardiac troponin has become increasingly valuable as a biomarker of MI. In 2007, the National Academy of Clinical Biochemistry Laboratory Medicine Practice Guidelines and the Joint European Society of Cardiology, American College of Cardiology Foundation, American Heart Association, and the World Heart Federation Task Force Guidelines recommended the use of cardiac troponin as a biomarker for the diagnosis of MI when used in conjunction with clinical evidence of myocardial ischemia (Refs. 1 and 2). Cardiac troponin has also been recommended in current clinical guidelines as a prognostic marker in patients with symptoms of acute coronary syndrome with respect to mortality, MI, or ischemic events. These recommendations solidified troponin's importance in MI diagnosis and triage; at the same time, they formalized an adjustment in the clinical cutoffs and changed the way troponin results were interpreted and used. There is a lot of interest in developing innovative troponin assays that aid in the diagnosis of MI and to support additional clinical uses of these assays. We are holding this public workshop to discuss several topics of interest that are important for the development of innovative cardiac troponin assays. The goal of the workshop is to enhance engagement with stakeholders concerning the development and validation of innovative troponin assay devices.

II. Topics for Discussion at the Public Workshop

This public workshop will consist of brief presentations providing information to frame the discussion, followed by interactive panel discussions. Following the presentations, a moderated discussion is planned to ask speakers and additional panelists to provide their individual perspectives. Topics for discussion include:

  • Clinical study design considerations and challenges
  • Subgroup differences for troponin's clinical use (e.g., the need for sex-specific cutoffs)
  • Reference range study design considerations and best practices for reference range study design and methods for calculating upper reference limits
  • The use of deltas in the diagnosis of MI
  • Point of care testing

In light of the changes to how troponin is used clinically, there is a need to explore and discuss troponin assay device development and evaluation. We are soliciting comments and feedback from stakeholders regarding additional topics for FDA to consider for discussion. These comments can be submitted to the docket prior to the meeting (see ADDRESSES). We anticipate that the comments and discussion at this public workshop will help facilitate the development of innovative troponin devices and lessen regulatory burden. The ultimate goal is to facilitate the availability of innovative, safe and effective troponin assay devices for patient care.
