MCM monitoring and assessment update

Monitoring and assessing medical countermeasures (MCMs) after they are dispensed or administered in response to a chemical, biological, radiological, or nuclear threat or an emerging infectious disease is vital to protecting public health, particularly in the case of MCMs that may have limited human efficacy data prior to use. FDA is a key partner—with other U.S. government agencies—in developing MCM monitoring and assessment capabilities, such as this new project.

New project: Examining the Ability to Conduct Influenza Antiviral Effectiveness Studies in Sentinel by Improving Confounding Control

This activity is the second project sponsored by the FDA Office of the Chief Scientist (OCS), Office of Counterterrorism and Emerging Threats (OCET) to explore how the Sentinel System may inform study protocols for medical countermeasure safety and effectiveness and to provide a valuable baseline for comparison during a public health emergency. The objective of this methods activity is to determine whether there is evidence of residual confounding in the association between influenza antiviral(s) and influenza complications in observational studies. (March 21, 2019)

Advancing development of new TBI treatments

On March 12, 2019, FDA qualified the OsiriX CDE Software Module, from the TBI Endpoints Development Initiative. This is the third qualification of a medical device development tool (MDDT) by the FDA, and the first of a biomarker test tool type.

A biomarker test is a lab test or instrument used to detect or measure an indicator of biologic processes or pharmacologic responses to a treatment (biomarker). This qualification provides a tool for more efficient development of devices in a critical area of medicine – traumatic brain injury (TBI) treatment.

FDA efforts to promote and foster blood pathogen reduction technologies

Ensuring the safety of blood products is one of our highest priorities. This owes not only to the important role that they play in medical care, but also to their unique risks. Blood products can be susceptible to contamination by both existing and emerging pathogens. In cases where the pathogens aren’t readily identified, there’s a risk that many people receiving blood products could be exposed to an emerging pathogen even before the danger is identified.

For these and other reasons, there’s a need for better safety measures to mitigate the potential risks to blood products. The good news is that the technology exists to potentially transform our assurance of safety of these blood products, while potentially reducing their cost.

The FDA Center for Biologics Evaluation and Research (CBER) is working with a variety of different partners to pursue multiple avenues of research to advance pathogen reduction technology. We believe perfecting these approaches is a critical priority.
